This list of unsolved deaths includes notable cases where victims have been murdered or have died under unsolved circumstances, including murders committed by unknown serial killers. The mysteriously-deceased are listed chronologically by year. (For 'serial killer cases' which span multiple years, entries are listed under the year the first murder took place.)
Fanny de Choiseul-Praslin, wife of French duke Charles de Choiseul-Praslin, died shortly after a beating and stabbing in the family's Paris apartment on 17 August 1847. Her husband was arrested, but committed suicide during trial, protesting his innocence all along. No other suspect has ever been identified. The scandal caused by the case helped to provoke the French Revolution of 1848.
Thomas C. Hindman, an American politician assassinated by one or more unknown assailants on 27 September 1868. The assassins fired through his parlor window while he was reading his newspaper with his children in Helena, Arkansas, United States.
Benjamin Nathan, 56, a financier turned philanthropist, was found beaten to death in his New York City home on July 28, 1870. Several suspects were identified, including Nathan's profligate son Washington, who discovered the body along with his brother. None were ever indicted and the case remains unsolved.
Henry Weston Smith, 49, a minister, was found dead on the road between his home in Crook City, South Dakota, and Deadwood, where he was going to give a sermon, on August 20, 1876. While he was not robbed, it has never been established who was responsible for his death, and what their motives were.
Martin DeFoor, 73, an early settler of Atlanta, Georgia, was along with his wife the victim of an unsolved axe murder on their farm on July 25, 1879.
John Henry Blake, 74, agent for one of Ireland's more despised British landlords, was shot and killed along with his driver on their way to Mass outside Loughrea on 29 June 1882. The case received considerable attention at the time because Blake's boss, Hubert de Burgh-Canning, 2nd Marquess of Clanricarde, was a nobleman. Although his wife survived the attack, she was unable to help identify any suspects, and the case remains unsolved.
John M. Clayton, American politician, shot and killed instantly by an unknown assailant on the evening of 29 January 1889 in Plumerville, Arkansas, after starting an investigation into the possible fraud of an election he took part in. After his death he was declared the winner of the election but his assassin was never found.
Andrew Jackson Borden and Abby Durfee Borden, father and stepmother of Lizzie Borden, both killed in their family house in Fall River, Massachusetts on the morning of 4 August 1892, by blows from a hatchet. In the case of Andrew Borden, the hatchet blows not only crushed his skull but cleanly split his left eyeball. Lizzie was later arrested and charged for the murders. She was the only one in the house at the time of the killing of Mrs. Borden. Lizzie and the maid, Bridget Sullivan, were the only ones in the home when Mr. Borden was killed. She was acquitted by a jury in the following year of 1893 and the case remains unsolved.
On August 9, 1894, a train was purposely derailed in Lincoln, Nebraska, killing 11 passengers and crew. Evidence at the scene showed signs of sabotage. The following year, a local man was convicted of second-degree murder. Doubts about his guilt led to his parole in 1910 due to lack of evidence; no other suspects have ever been identified.
The Gatton murders occurred 1.5 miles (2.4 km) from the rural Australian town of Gatton, Queensland, on December 26, 1898. Siblings Michael, Norah and Ellen Murphy were found deceased the morning after they left home to attend a dance in the town hall which had been cancelled. The bodies were arranged with the feet pointing west and both women had their hands tied with handkerchiefs. This signature aspect has never been repeated in Australian crime and to date remains a mystery.
William Goebel, an American politician who was shot and mortally wounded on the morning of 30 January 1900 by an unknown assailant in Frankfort, Kentucky, one day before being sworn in as Governor of Kentucky. The next day the dying Goebel was sworn in and, despite the best efforts of eighteen physicians attending him, died on the afternoon of 3 February 1900. Goebel remains the only state Governor in the United States to die by assassination while in office.
Rose Harsent, a six-months-pregnant maid who was stabbed to death on 1 June 1902 in Suffolk, England by an unknown assailant. At the time it was alleged that the murderer was a preacher of the Primitive Methodist Chapel named William Gardiner, who was having an affair with the victim. Gardiner was tried twice for the murder but each time the jury failed to reach a verdict. The case has been investigated in BBC One's Julian Fellowes Investigates.
Elsie Sigel, 20, found strangled inside a trunk in an apartment in New York City's Chinatown on June 18, 1909, nine days after she had last been seen. The resident of the apartment, who had been having a love affair with her, was considered the prime suspect but was never arrested.
Elsie Paroubek, the five-year-old daughter of Czech immigrants. Is thought to have either wandered away from her home or was kidnapped in Chicago on April 8, 1911. Her disappearance was the subject of intense police investigation over three states, with massive newspaper coverage. Her body was found a month later. Elsie, under the name "Annie Aronburg" became one of the principal characters in Henry Darger's immense novel The Story of the Vivian Girls in the Realms of the Unreal.
Joseph Wilson, the sixty-year-old stationmaster was shot dead at Lintz Green railway station in the Northeast of England on 7 October 1911. His murder sparked one of the largest murder investigations in Northeast England.
One suspect in the Villisca Axe Murders, which claimed eight lives in that Iowa town on the night of June 9–10, 1912, was tried twice and ultimately acquitted. Other suspects have been considered, but history has largely exonerated them as well.
Chinese journalist Huang Yuanyong, 30, was shot and killed in San Francisco on December 25, 1915. No arrests were ever made. Most theories about the responsible parties suggest that it was a political assassination, since Huang had increasingly been in conflict with the government of the newly established Republic of China after initially supporting it.
John Bamford was considered the prime suspect in the 1917 Wonnangatta murders; however, his body was found early the following year. The cause of death was a gunshot wound to the head. Several theories have been advanced, but no suspects have ever been identified. In the late 1970s, Barclay's son, who later worked for a mutual friend of the two who had been an early suspect, made a statement suggesting he knew who the murderers were as well but declining to identify them.
De La Haye, principal of the Newington House school in Madras, India, was shot dead in his bed at the school on 15 March 1919. One defendant was acquitted after a highly publicized trial; no others have ever been identified.
James Colosimo, 42, gangster who led a precursor to the Chicago Outfit. He was shot and killed at his café on May 11, 1920. No one was ever charged with the killing; it is believed that Al Capone, then one of Colosimo's henchmen, was involved.
Joseph Bowne Elwell, 46, a bridge player, was shot and killed inside his locked house on June 11, 1920. One clearly false confession the next year was discarded, and no other suspects ever were identified. The intense media interest in the case inspired the development of the locked-room murder subgenre of detective fiction.
Italian anarchists were suspected in the Wall Street bombing of September 16, 1920, which killed 38, making it the deadliest terrorist act in U.S. history at that point. Despite a number of arrests, no one was ever charged. One likely suspect, who was never arrested, fled to Italy shortly afterwards and never returned to the U.S.
"Little Lord Fauntleroy", an unidentified boy who was murdered in late 1920 or early 1921 and was found on 8 March 1921. He was killed by a blow to the head and drowning after being dropped into a quarry in Waukesha, Wisconsin, United States.
Anthony D'Andrea, 48, an early Chicago Mafia boss, was shot and killed while entering his apartment on May 11, 1921, near the end of the city's aldermen's wars. No one was ever charged or named as a suspect.
Professional golfer James Douglas Edgar, 36, whose book The Gate to Golf changed the sport considerably, died shortly after he was found on an Atlanta street late at night on August 8, 1921, with a leg wound. Reports that this was the consequence of his involvement in a love triangle have never led to any suspects being identified.
William Desmond Taylor, a popular Irish-born American actor and director of silent movies. Killed by a shot in the back on 1 February 1922 inside his bungalow. His murder, along with other Hollywood scandals, such as the Roscoe Arbuckle trial, led to a frenzy of sensational and often fabricated newspaper reports, and a deathbed confession of dubious veracity.
The Hinterkaifeck murders. Hinterkaifeck, a small farmstead between the Bavarian towns of Ingolstadt and Schrobenhausen (approximately 70 km north of Munich), was the scene of one of the most puzzling crimes in German history. On the evening of 31 March 1922, the six inhabitants of the farm were killed with a pickaxe, and the murder is still unsolved.
Edward Hall and Eleanor Mills, both of New Brunswick, New Jersey, were found dead of gunshot wounds in a field in nearby Franklin Township on September 16, 1922. Hall, an Episcopalian priest, had apparently been having an extramarital affair with Mills, who sang in the church choir. His wife and her brothers were charged with the crime. After one of the first trials to attract heavy media interest, they were acquitted of all charges. No other suspects were ever identified.
The plane crash that killed early aviator B. H. DeLay, 31 a pioneering stunt pilot, on July 4, 1923 in Venice, California, was found to have been the result of sabotage to the aircraft. No one was ever formally charged or identified as a suspect.
Father Hubert Dahme, a popular local Catholic priest, was shot dead at an intersection in Bridgeport, Connecticut, on February 4, 1924. A local vagrant, Harold Israel, was arrested and charged with the crime; but at trial prosecutor Homer Stille Cummings, later U.S. Attorney General, not only dropped the case but discredited the evidence the city's police department had collected against Israel. No other suspects have ever been named; thirty years later a witness to the killing said it was not Israel but refused to identify the real killer out of fear for their life.
The Janet Smith case. On July 26, 1924, the 22-year-old Scottish nursemaid was found dead of a gunshot wound to the temple in a home in an exclusive neighborhood of Vancouver, Canada. Although she was initially labeled a suicide (despite much evidence to the contrary), her friends were able to get the case reopened and deemed a murder. The initial suspect, Chinese houseboy Wong Foon Sing, was kidnapped and tortured for weeks in an unsuccessful attempt to extract a confession, causing a major scandal when it was discovered that various police officials and respected members of society were directly involved. Wong was eventually tried and acquitted for lack of evidence. A law was proposed, banning the employment of Orientals and white women in the same household, but failed to pass.
The Milaflores Massacre: Three Detroit gangsters were shot down in the Milaflores Apartments on March 28, 1927. The killings are widely believed to have been a revenge attack by members of The Purple Gang; two members were arrested the next day but never charged.
The Killing of Lizzie O'Neill in Dublin was the shooting of a prostitute who was also known as Honour Bright. Two suspects were brought to trial, but were acquitted.
Jewish gangsterArnold Rothstein, 46, an avid gambler best remembered for his alleged role fixing the 1919 World Series, died on November 6, 1928, of gunshot wounds inflicted the day before during a New York City business meeting. He refused to identify his killer to police. A fellow gambler who was believed to have ordered the hit as retaliation for Rothstein's failure to pay a large debt from a recent poker game (Rothstein in turn claimed it had been fixed) was tried and acquitted. No other suspects have ever emerged.
It is historically accepted that Al Capone ordered the St. Valentine's Day massacre of seven other gangsters in Chicago on February 14, 1929. But neither he nor any of the suspected gunmen (many of whom were dead themselves within a few years) were ever formally prosecuted for the crime.
The Wallace Case was the unsolved murder of Liverpool housewife Julia Wallace on 20 January 1931. Her husband, William Herbert Wallace, was convicted and sentenced to hang, but the verdict was overturned on appeal - the first such instance in British legal history. The chess-like quality of the puzzle has attracted a host of crime writers. Raymond Chandler said, 'The Wallace case is the nonpareil of all murder mysteries ... I call it the impossible murder because Wallace couldn’t have done it, and neither could anyone else. ... The Wallace case is unbeatable; it will always be unbeatable.'
Jack "Legs" Diamond, American gangster, was found shot to death in the Albany, New York, apartment of his mistress on the morning of December 18, 1931. While he had many enemies among the underworld who wanted him dead, Daniel P. O'Connell, boss of the city's political machine, claimed in an interview with author William Kennedy four decades later that he had ordered the killing after Diamond ignored police warnings to stay out of the city's rackets. The case remains officially unsolved.
The murder of Vera Page occurred on 14 December 1931. Page was a 10-year-old schoolgirl from Notting Hill, London, who was last seen walking towards her own house, having visited her aunt to show her new swimming certificates she had been awarded. Her raped and strangled body was found two days later. Despite strong circumstantial evidence linking a local man named Percy Rush to the crime, a jury recorded an open verdict of "Murder by person or persons unknown."
Vampire Murder Case is the nickname given to the case of an unknown assailant who committed the unsolved murder of a prostitute who was found dead with a crushed skull in her apartment on 4 May 1932 in Stockholm, Sweden. Police noted that someone had drunk her blood.
American journalist Walter Liggett, 49, was shot in Minneapolis, Minnesota, on December 9, 1935, while investigating connections between that state's governor and organized crime. No suspects were ever identified.
Pete Panto, 28, a labor leader who had fought Mafia control of the International Longshoremen's Association local on the Brooklyn docks, was found in a Lyndhurst, New Jersey lime pit in January 1941. He had not been seen since leaving his house on July 14, 1939. No one was ever arrested in the case; one suspect who was questioned was found dead a month later.
Carlo Tresca, 63, an Italian American labor leader who led opposition to Fascism, Stalinism and Mafia control of unions, was shot dead at a Manhattan intersection on the night of January 11, 1943. Given the enemies he had made and their propensity for violence, the list of potential suspects was long; however the investigation was incomplete and no one was ever officially named. Historians believe the mostly likely suspect was mobster Carmine Galante, later acting boss of the Bonanno family, seen fleeing the scene, who had likely acted on the orders of a Bonanno underboss and Fascist sympathizer Tresca had threatened to expose.
Sir Harry Oakes, an American-born British gold-mine owner and philanthropist who was found murdered in his mansion in Nassau, Bahamas on 8 July 1943. His murder became the subject of worldwide press coverage at the time as well as several books, films, and documentaries.
Actor David Bacon, best known for playing Bob Barton in the Masked Marvel serials of the 1930s, died shortly after crashing his car in Santa Monica, California on September 12, 1943. Afterwards he was found to have been suffering from a stab wound to the chest; no suspect has ever been identified.
Georgette Bauerdorf, a 20-year-old oil heiress who was found face down in a bathtub in her home at West Hollywood, California, on 12 October 1944. She had been strangled with a piece of towel stuffed down her throat, and although there was a large roll of $2 bills and thousands of dollars worth of sterling silver lying in an open trunk, Bauerdorf's jewelry and other valuables were not stolen. The police believe her murderer had unscrewed an automatic night light over the outside entrance of the apartment so it would not come on and lain in wait for her.
Tamil film critic C.N. Lakshmikanthan was stabbed while riding back to his Madras, India, home on 8 November 1944; he died in hospital the next day having been able to describe the attack to police but not identify the assailants. Six men, all film actors whom he had feuded with, were arrested; three were tried and two convicted. Their convictions were overturned on appeal three years later but their film careers were ruined. No other suspects have ever been identified.
Ernst Dehmel, 30, a decorated officer in the German Waffen-SS, was allegedly beaten to death by French soldiers who had him in their custody at Remscheid-Lüttringhausen on 7 August 1945. No charges have ever been brought.
The Black Dahlia (Elizabeth Short), a 22-year-old woman who was found severely mutilated and her body cut in half in Leimert Park, Los Angeles, California on 15 January 1947. Her unsolved murder has been the source of several books, films, and widespread speculation.
Later that year in nearby Beverly Hills, on June 20, gangster Bugsy Siegel, known for making Las Vegas into a gambling destination, was shot several times with a high-powered carbine from outside as he read the newspaper at a friend's house. There are many suspects. Police believe he was killed by his own associates, but have never put together enough evidence against any one of them to declare the case solved.
Taman Shud Case, an unidentified man was found dead on Somerton beach in Adelaide, South Australia on the morning of December 1, 1948 at 6:30 a.m. Also known as the Mystery of the Somerton Man, this case is considered "one of Australia's most profound mysteries", and no suspects have been named nor has the man ever been identified despite the best efforts of many world agencies. He was killed by an unknown poison with a piece of paper in his pocket that reads "Taman Shud", meaning "The End".
Emily Armstrong, found in a dry cleaner's shop in London, England on 14 April 1949, about an hour after she had been murdered. An autopsy showed she was beaten to death and her skull shattered by at least 22 blows from a blunt object, believed to be a claw hammer.
Three people died when a train derailed near Matsukawa, Japan on August 17, 1949. Investigators found that the track had been sabotaged going into a curve and arrested 20 people; all of whom were initially convicted and, in several cases, sentenced to death. However, during the appeals process, it eventually emerged that prosecutors had suppressed exculpatory evidence, and after all the defendants were released in 1970 the case was closed. No other suspects have ever been identified.
Arnold Schuster, 24, a clothing salesman who had provided the tip that led to the capture of legendary bank robber Willie Sutton, was shot dead outside his Brooklyn home a month afterwards, on March 8, 1952. Police interviewed 300 people but never identified any as a suspect, although they came to believe the killing was carried out by either the Mafia or Sutton's associates. A lawsuit against the city by his family led to a landmark state-court ruling that the state has a duty to protect anyone who cooperates with the police to the extent that they seek.
John Acropolis, 43, a New York labor leader with organized crime connections, was shot by an unknown assailant in Yonkers on August 26, 1952.
Jack Burris, 35, Mayes County, Oklahoma, county attorney, was killed by a shotgun blast just outside his house in June 1952. Investigators were unable to obtain a tape that purported to be the killer's confession later in the decade; there have been no suspects since then.
Kyllikki Saari (back right), murdered in Isojoki, 1953. Her case remains one of Finland's most infamous unsolved murder cases
The body of Kyllikki Saari, 17, of Isojoki, Finland, was found on October 11, 1953, almost five months after she was last seen. Several suspects have been considered but no one has ever been prosecuted. The case remains one of the country's best-known mysteries.
On April 9, 1953, the body of 21-year-old Wilma Montesi washed up on a beach at Torvaianica, Italy, near Rome. The investigation delved into accounts of orgies and drug use in Roman society, but no one was ever charged.
Alma Preinkert, 58, registrar of the University of Maryland, was stabbed by an intruder in her Washington home on February 28, 1954, and died shortly afterwards. No suspect has ever been named.
Marilyn Reese Sheppard, wife of Sam Sheppard, attacked and killed in her home in Bay Village, Ohio, United States, on 4 July 1954. Sam Sheppard was later convicted of killing his pregnant wife, but this was overturned in 1966, and he was acquitted in a new trial. He claimed his wife was killed by a bushy-haired man who also attacked him and knocked him unconscious twice. Their son slept through the night, just down the hall from the bedroom in which his mother was murdered. The trial of Sam Sheppard received extensive publicity and was called "carnival atmosphere" by the U.S. Supreme Court. The Sheppard case was a large part of the inspiration for the television series and later movie The Fugitive.
Carolyn Wasilewski, 14, was found dead in a rail yard near her Baltimore home on November 9, 1954. The case generated nationwide media attention, and police still get calls about the case. However, no suspects have ever been named. Filmmaker John Waters says the case and the media frenzy over some aspects of Baltimore's youth culture of the time inspired his film Cry-Baby, later adapted into a Broadway musical.
William Morris Bioff, 55, a labor leader with organized-crime ties, was killed by a bomb that detonated when he started his car on the morning of November 4, 1955, outside his Illinois home. No suspects have ever been named.
Mafia boss Albert Anastasia, 55, was shot to death while being shaved at a Manhattan barbershop on October 25, 1957. The list of suspects includes many other organized-crime figures of the era; no one has ever been officially named although authorities think the actual assassins were members of the Boston-based Patriarca crime family, in keeping with the mob's practice of hiring for such major hits from out of town.
Rosemarie Nitribitt, 24, a prostitute, was found dead in her luxury apartment in Frankfurt, Germany, on 1 November 1957. She had been strangled and beaten; the investigation established that this had happened three days beforehand. Police arrested Heinz Pohlmann, a businessman and friend of Nitribitt's who had visited her that day. He was tried and eventually acquitted due to questions about whether the time of death had been accurately established. No other suspects have ever been identified; the case has inspired novels, films and plays.
Barbara and Patricia Grimes disappeared on 28 December, 1956, in Chicago, Illinois after going to a cinema to watch an Elvis Presley movie. Their disappearance launched one of the biggest missing-persons hunts in Chicago history. However, police were not able to determine what happened to the Grimes sisters. On January 22, 1957 their naked bodies were found off a road near Willow Springs, Illinois. The corpses contained various bruises and marks (for example puncture wounds in the chest that may have come from an ice pick) that were never fully explained.
Gus Greenbaum, 62, another Chicago Outfit figure, was stabbed and beaten to death along with his wife in their Phoenix, Arizona, house on December 3, 1958, supposedly as punishment for his continued skimming of casino profits. No suspects were ever identified.
Lynne Harper, 12 years old, was last seen alive on 9 June 1959 riding on the handlebars of her friend Steven Truscott's bike near an air force base which is now Vanastra, Ontario, Canada. Two days later her body was discovered in a nearby farm woodlot. She had been raped and strangled with her own blouse. Fourteen-year-old Steven Murray Truscott was convicted and sentenced to death for the murder, becoming Canada's youngest person to be sentenced to death. The sentence was later commuted to life in prison. Truscott was held in custody for 10 years: in 2007 his conviction was ruled a miscarriage of justice, although he was not declared innocent.
Almost 600 possible suspects have been considered in the Walker family murders of December 12, 1959, in which two children and their parents were shot by intruders at their Osprey, Florida, farmhouse. Among them are the two men executed by Kansas for the Clutter family murders, which formed the basis for Truman Capote's In Cold Blood.
All 34 passengers and crew aboard National Airlines Flight 2511 from New York to Miami were killed on January 6, 1960, when a bomb exploded aboard the plane in mid-flight. The FBI is still investigating the case and no suspects have been named.
The Lake Bodom murders were an infamous multiple homicide that took place in Finland on 5 June 1960. That night four teenagers were camping on the shores of the Finnish lake when between 4 am and 6 am, they were attacked by an unknown individual or individuals with a knife and a blunt object. Three of them died, and the fourth one was wounded but survived. Although the sole survivor became a suspect for some time in 2004, the case remains unsolved and the killer(s) unidentified.
Louis Allen, 44, was shot dead on January 31, 1964, on his Liberty, Mississippi, farm. An African American who had attempted to register to vote and reportedly was willing to talk to federal investigators about a 1961 murder of another black Liberty resident by a white state legislator, Allen had faced increasing harassment and was to move to Wisconsin the next day. The sheriff at the time, Daniel Jones, has long been suspected of involvement; in a 2011 television interview he denied it. No one has ever been prosecuted.
Mary S. Sherman, 51, an orthopedic surgeon, was found dead of stab wounds and burns in her New Orleans apartment on July 21, 1964. No suspects have ever been named.
The bodies of Marianne Schmidt and Christine Sharrock, both 15, were found beaten and stabbed on Wanda Beach near Sydney on the morning of 11 January 1965, having last been seen on the beach the previous evening; the killer had apparently also attempted to rape them. Several suspects have been identified over the years, but none ever formally charged; a DNA sample was taken from the preserved blood and semen at the scene but it is not known if a match has been made.
Similarly, the bombing that killed all 66 passengers and crew of Cyprus Airways Flight 284 over the Mediterranean between Greece and Cyprus on 12 October 1965 remains unsolved.
Early in the morning of June 17, 1966, two men, later described by witnesses as African American, walked into a Paterson, New Jersey, bar and began shooting. The bartender and one patron died at the scene; a female customer died of her wounds a month later. Former professional boxer Rubin Carter and a friend, John Artis, were charged with the crime and convicted the following year, despite their own alibi, weak evidence and alleged racial bias by police and prosecutors. They always protested their innocence, and their case became a cause celebre, inspiring Bob Dylan's "Hurricane". In 1978 they won a second trial but were convicted again; after another habeas corpus petition was granted in 1985, the state declined to retry them. No other suspects have ever been identified.
For almost 30 years after Barbara Ann Hackmann Taylor's body was found alongside a road near Georgetown, Kentucky, on December 17, 1968, it was known only as "Tent Girl". Since her identification in 1998, what investigation that has been possible has identified her husband at that time, now dead.
Clarence 13X, 41, founder of Five-Percent Nation, a splinter group of the Nation of Islam, was fatally shot by a group of attackers in the lobby of his wife's Harlem apartment building on the morning of June 13, 1969. One suspect was arrested two months later; charges were dropped. New York police believe the murder was related to an extortion attempt; no other suspects have ever been named.
Betsy Aardsma was a 22-year-old woman from Holland, Michigan, United States and a graduate student at Penn State University, who was stabbed to death in broad daylight in the stacks of Pattee Library on Penn State's campus on 28 November 1969. She was stabbed a single time through the heart with a single-edged small knife. Approximately one minute later two men came from Betsy's location and told a desk clerk, "Somebody better help that girl," and then left the library. The men were never identified. 25–35 minutes later Betsy arrived at a hospital where she was pronounced dead. She had been wearing a red dress, and since there was only a small amount of blood visible, no one realized immediately that she had been stabbed.
The bodies of Harvey and Jeannette Crewe, both 29, were found in New Zealand's Waikato River near their Pukekawa farm, a month apart in August and September 1970. They had been reported missing on 22 June of that year, five days after last being seen; both had been killed with a rifle. After a short investigation, police arrested Arthur Thomas, another farmer, later that year. He was tried and convicted twice, but evidence that police had fabricated key evidence against him led to an inquiring commission that severely criticized two of the lead investigators without holding them accountable otherwise, and Prime Minister Rob Muldoon pardoned Thomas in 1979. Authorities have never identified any other suspects, although two journalists have written books proposing alternative theories of the case.
Investigations have strongly suggested that Italian journalist Mauro de Mauro, 49, was killed by the Mafia to prevent him from completing his own inquiry into the death of Enrico Mattei after he was kidnapped while returning from work in Palermo. However, it has never been clear which of several possible motives led to his death, and his body has never been found. In 2011, the only living suspect was tried and acquitted; the prosecution continues to appeal.
Joe Gallo, 43, was shot to death in a Manhattan clamhouse on April 7, 1972, as part of a war between New York City Mafia families. The investigation identified no suspects, although Frank Sheeran claimed shortly before his death 31 years later that he was the lone gunman.
On April 20, 1972, New York City police officer Philip Cardillo, 32, died in the hospital of a gunshot wound inflicted six days earlier during an incident at a Harlem mosque. Another officer involved said he had seen one of the mosque's congregants, Louis 17X Dupree, standing over Cardillo with a gun pointed at his chest. Due to political complications resulting from the incident, suspects who had been in custody were not identified before being released and evidence was not collected at the scene; the detective in charge of investigating the shooting later claimed interference from senior officers impeded his efforts and procedures were ignored. Two years later, Dupree's first trial, based largely on the testimony of an informant, resulted in a hung jury and his second in an acquittal; he later served a prison sentence in North Carolina on drug charges and is currently in a Georgia prison on another charge. A later police informant in another case identified another suspect; he was never tried. Detectives who continue to investigate the case have complained that the FBI, which also had informants within the mosque, lied about what it knew in the past and is still withholding relevant information.
Parts of Dolores Della Penna's body were found in two separate South Jersey locations in July 1972. The Philadelphia 17-year-old had last been seen leaving her house in the city's Tacony neighborhood on July 11. Her fingertips had been removed from her arms to prevent fingerprint identification and her head has never been found. In the mid-1990s police identified several suspects and claimed the motive had been revenge against her boyfriend for stealing drugs from some local dealers; however most of them were dead by that time and the living ones were not charged. No other suspects have ever been identified.
Thomas Eboli, 61, acting boss of the Genovese crime family, was shot and killed as he walked from his girlfriend's house in the Crown Heights section of Brooklyn to his car in the early hours of July 16, 1972. It has been speculated that he was killed over unpaid debts, but no one has ever been charged.
Yosef Alon, 43, a military attaché at the Israeli embassy in Washington, was shot fatally in his Chevy Chase driveway as he and his wife returned from a party shortly after midnight on July 1, 1973. The Palestinian Black September terrorist group claimed responsibility, in retaliation for the slaying of one its members by Israeli operatives, but officially the case remains unsolved.
Athalia Ponsell Lindsley, 56, a former model and Broadway dancer, was fatally assaulted with a machete on the porch of her St. Augustine, Florida, home on January 23, 1974. The investigation centered on a neighbor she was having a dispute with at the time; he was tried and acquitted due to mishandling of the evidence. No other suspects have been named.

Karmein Chan, 13, was abducted from her family's home in Templestowe, Victoria by an unidentified man who was later dubbed "Mr. Cruel" by Melbourne newspapers on April 13, 1991. Her body was discovered on April 9, 1992 in Thomastown, she had been shot in the head. Though Victoria Police knew a great deal about the perpetrator from previous, non-fatal child abductions and rapes dating back to 1985, there has never been enough evidence to charge any of the 27,000 men interviewed at the time. The case is still open with a second police operation, Taskforce Apollo, formed in 2010 to examine new evidence and material from the original Operation Spectrum. If the perpetrator is still alive he would be between approximately 60 and 75 years old in 2014. The murder of Karmein Chan is still one of the extensive and expensive investigations in Victorian history, with a combination of investigative errors and the perpetrator's precautions preventing his identification and arrest.

He had been strangled with a belt, which was still around his neck, after being beaten (and bandaged); she had been shot several times with one of the couple's hunting rifles after her hands were tied behind her back. She may have injured one of their attackers, who apparently also tried to kill the couple's dog with poison gas, while fighting back. A safe was left open and documents were taken from it while valuables were left behind. The killings were found to have occurred two days before; friends and family say that Jaroszewicz, who was obsessed with security to begin with, had been acting extremely paranoid in the days before the murders. No suspects have been named.

Her ex-husband, former professional football star O.J. Simpson, was arrested and charged with the crime two days later; after an eight-month trial covered heavily by the media, in which the defense argued that there had been extensive mishandling of the evidence and that some investigators were racially biased, he was acquitted. However, strong public sentiment remained that he was guilty, and he was held liable in a suit by the victims' families later. No other suspects have ever been identified.
The 18 July 1994 suicide bombing of a Jewish organization's building in Buenos Aires killed 85, surpassing the similar attack on the Israeli embassy two years earlier as Argentina's deadliest terror attack. Five suspects, four of whom were local police officers, were acquitted in a 2004 trial; the investigating judge was removed from the case and later impeached after it was disclosed that he had paid for evidence. British authorities arrested an Iranian suspect named by Argentina in 2003 but declined to extradite him due to weak evidence. No other suspects have been named although investigations continue, one of which has since led to the unsolved death of Alberto Nisman, the investigating prosecutor.
The day after that bombing, another suicide bomber brought down a plane in Panama, killing 21, 12 of whom were Jews. While an apparently fictitious Arab terrorist organization claimed responsibility, no suspects have ever been identified.
Irish crime boss Martin "The General" Cahill, 45, was shot and killed at a Dublin intersection on 18 August 1994.

No arrests have ever been made.
Johan Heyns, 66, an Afrikaner Calvinisttheologian, was shot and killed from outside his house in Pretoria, South Africa's capital, while playing cards with his wife and grandchildren on 5 November 1994.

Deanna Cremin, a 17-year-old girl from Somerville, Massachusetts, United States, was murdered on March 30, 1995. Her body was found behind a senior housing complex.

Her murder remains unsolved.
Michael Nigg, 26, an aspiring actor and waiter at a Los Angeles restaurant, was shot and killed during an attempted robbery on September 8, 1995 while withdrawing money from an ATM. Three suspects were arrested a month later but released for lack of evidence and the case remains unsolved. Since Nigg was a friend of Ronald Goldman, with whom he had worked, and seemed to live quite well for someone in his position, leading to some reports that he was involved in drug trafficking, his death has been used to support theories that the murders of Goldman and O.J. Simpson's ex-wife Nicole the year before was in fact drug-related as well.
Mitchell Bates, a sleeping-car attendant for Amtrak, was killed when the Sunset Limitedderailed on October 9, 1995, near Palo Verde, Arizona. Investigators later found notes from a group identified as the "Sons of the Gestapo", supposedly angry over the Waco Siege earlier that year. The tracks were found to have been tampered with in a way that circumvented safety warning systems, suggesting a perpetrator with knowledge of rail operations. No suspects have ever been identified, however, although the FBI believes the real plan was to rob a passing freight and there were no terrorist motivations.
Rapper Randy Walker, 27, better known as Stretch, was shot and killed by the occupants of a vehicle passing his minivan in Queens Village, New York, shortly after midnight on November 30, 1995.

Amber Hagerman, victim of an abduction and murder. On 13 January 1996, the 10-year-old girl was kidnapped while riding her bike near her grandparents' home in Arlington, Texas. Four days later, a man walking his dog found her body in a creek bed. An autopsy revealed that her throat had been cut. Although a $75,000 reward was offered for information leading to Hagerman's killer, the perpetrator was never found. Her murder would later inspire the creation of the AMBER Alert system.
Sophie Toscan du Plantier. Wife of French filmmaker Daniel Toscan du Plantier, found beaten to death outside her home in Toormore near Schull in County Cork, Ireland, on the morning of the 23 December 1996. Former French President Jacques Chirac was a friend of the couple and gave the case national attention.

In early April, 2010 the French authorities issued an arrest warrant for Mr. Bailey. On 24th, April, 2010 the Gardaí in Ireland arrested Ian Bailey and brought him in front of the High Court in Dublin to appeal his extradition. This case is ongoing and is expected to take many months.
JonBenét Ramsey, a six-year-old American girl who had competed in child beauty pageants, was made famous by her Christmastime murder and the subsequent media coverage. She was found dead in the basement of her parents' home in Boulder, Colorado, on December 26, 1996, nearly eight hours after she was reported missing. The official cause of death was asphyxia due to strangulation associated with craniocerebral trauma. After several grand jury hearings, the case is still unsolved. Her parents were suspects, but authorities eventually confirmed that the couple had been cleared of any involvement.
On February 5, 1997, Richard Aderson, 47, a school administrator from LaGrange, New York, had a minor collision with another driver just before crossing the Newburgh-Beacon Bridge along Interstate 84.

Jane Thurgood-Dove, 35, was shot outside her car, in full view of her young children, as she pulled into the driveway of her home in the Melbourne suburb of Niddrie on 6 November 1997; the killer escaped into a waiting getaway car which was found, burnt, shortly afterwards not too far away. Her husband and a police official believed to have been infatuated with her have been eliminated as suspects. More recently a theory has been floated that the killers were members of a local biker gang who had mistaken her for their real target, another local woman of similar appearance married to a fellow criminal. Police believe that the shooter and getaway car driver have since died of a heart attack and boating accident respectively; they have offered the remaining participant immunity if he testifies against the man whom they believe ordered the killing.
On 1 January 1998, the body of Australian 14-month-old Jaidyn Leskie was found in a lake far from his home. He had been kidnapped the previous June. Greg Domaszczewicz, acquitted of the murder charge after a 1998 trial, was nevertheless found by a 2006 inquest to have had at least a contributing role in the crime, including the disposal of the body. However, current double jeopardy laws in Victoria do not allow the state to try him again, and the case is still officially unsolved.
Stephanie Crowe, 12, was found stabbed to death in her Escondido, California, bedroom on the morning of January 21, 1998. Since there were no signs of forced entry, police focused on and eventually arrested her older brother Michael and two friends; however, charges against them were abruptly dimissed when later lab tests found several drops of Crowe's blood on a local transient. He was tried and convicted, but that was overturned on appeal and a 2013 retrial acquitted him.

On March 25, 1998, NASCAR driver Chris Trickle, 24, died of injuries sustained in a Las Vegasdrive-by shooting on February 9, 1997. A quirk in Nevada law at the time meant that the gunmen could not be prosecuted for his murder, since his death had occurred more than a year and a day after the attack; it was subsequently changed. No suspects have ever been identified, and the case is considered cold.
Marek Papała, 38, former Chief of Polish State Police, was shot in the head on 25 June 1998 while parking his car. In 2012 a former car thief turned state witness given immunity of prosecution came forward with the revelation that he had killed Papała. He also testified some Polish mafia bosses had encouraged the crime. However, in 2013 the indictment against the mafia bosses was dropped due to numerous factual and logical inconsistencies. The murder of Papała remains unsolved.
Ita Martadinata Haryono, an Indonesian human rights activist, found dead on 9 October 1998 in her bedroom in Central Jakarta, Indonesia. She was stabbed ten times and her neck had been slashed.

They have suspects, who are currently in prison, but have not publicly identified them.
Jill Dando, an English journalist and television presenter who worked for the BBC for 14 years. She was killed by a single gunshot wound to the head on 26 April 1999, after leaving the home of her fiancé. Her death sparked "Operation Oxborough", the biggest murder inquiry and largest criminal investigation since the hunt for the Yorkshire Ripper.
On June 12, 1999, exactly seven months after her disappearance, the body of 13-year-old Christina Marie Williams was found on the former Fort Ord Army base next to California's Monterey Bay. Police suspect a man in prison for other abductions; in 2011 a woman recanted her corroboration of his 1998 alibi in the case, saying she had been threatened into making it. However no charges have been filed.
Ricky McCormick whose body was found in a field by sheriff's officers in St. Charles County, Missouri, on June 30, 1999. The only clues to the mystery are two notes in his pockets, apparently written in a complex cipher.

Later that month, a 55-gallon drum in the basement of a house in Nassau County, New York, turned out to contain the pregnant body of Reyna Marroquin, an El Salvadorean immigrant murdered 30 years earlier. Police suspected a former owner of the house who had also run a dye company that used the drum. He had reportedly been having an affair with Marroquin. The day after police interviewed him in Florida and told him they would get a court order to produce a DNA sample, he killed himself. DNA tests later showed he had fathered the fetus. Police consider him their main suspect, but as he is dead himself he cannot be charged and the case remains officially open.

John Gilbride, 34, a baggage handler for US Airways at Philadelphia airport, was shot dead in his car outside his home in Maple Shade, New Jersey on September 10, 2002. He was involved in a custody dispute with his former wife, the widow of the founder of the radical group MOVE, and was worried that members of the group might carry out threats they had made to kill him. While other former members of MOVE believe the group is responsible, and current members assert in turn that the murder was either faked or that the government did it in an attempt to frame them, it has also been suggested that gambling debts were involved. No suspects have been identified.
Jennifer Servo, 22, a TV news reporter, was found beaten and strangled in her Abilene, Texas, apartment on September 16, 2002. Police have suspected either her former boyfriend or a coworker she had begun a new relationship with, but so far lack the evidence to arrest either.

The body of a 2-year-old boy found wrapped in a blanket off an interstate highway near Naperville in DuPage County, Illinois, on October 8, 2005, was identified six years later as Atcel Olmedo. The exact cause of death was impossible to determine due to the condition of his remains, but it appeared he had been severely beaten. His mother and stepfather are considered possible suspects; they are believed to have returned to Mexico.
The Jeff Davis 8: Eight women, all involved in prostitution and/or drugs, were found dead in Jefferson Davis Parish, Louisiana, between 2005 and 2009.

Rashawn Brazell, disappeared after leaving his home in Bushwick, Brooklyn, New York, United States, on the morning of 14 February 2005. His dismembered body parts were later found in garbage bags. America's Most Wanted profiled the case five times, most recently in 2008.
South African businessman Brett Kebble, 41, was fatally shot in his car on 27 September 2005 while driving along Johannesburg's M1 motorway to a dinner engagement. The bullets used were a special low-powered type normally used by bodyguards and security personnel to reduce the likelihood of injuries to people other than those targeted. Another South African businessman, Glenn Agliotti, was charged with the crime a year later but acquitted in 2010 when the court hearing the case ruled that the state had not presented a case against him strong enough to require trial. No other suspects have ever been named.
Mario Condello, 53, a member of the Australian Mafia, was fatally shot in the driveway of his Brighton home on 6 February 2006, the day before he was to stand trial for plotting to murder another mob boss, Carl Williams. While Williams would later be convicted of in turn conspiring to have Condello murdered, and police believe the killer was a hit man currently in prison for another killing, the murder officially remains unsolved.
Frauke Liebs, 21, a student nurse, was last seen alive leaving a pub in Paderborn, Germany, late on 20 June 2006; she never returned nor did she show up for work the next day. Over the next week her family and friends received telephone calls and texts from her in which she seemed vague and evasive about what was happening; after she intimated that she was under duress in the last one the call was cut short. Her body, in an advanced state of decomposition, was found in a forest two months later with the same clothes she had worn when last seen. Police believe she was abducted and murdered but have not named any suspects.
The strangled body of Chanel Petro-Nixon, 17, was found in a garbage bag on a Brooklyn street June 22, 2006, four days after she had been reported missing. No suspects have ever been identified.
Robert Wone, age 32, was murdered on August 2, 2006, in his friend's Washington, D.C., apartment. He was "restrained, incapacitated, and sexually assaulted" prior to his death. The only individuals present in the apartment at the time were its three residents, all friends of Wone. They have denied involvement and insisted that an intruder committed the crime. Authorities claim that there was no evidence of a break-in: the apartment appeared to be washed and cleaned, the three residents appeared freshly showered, and the evidence was not consistent with the residents' accounts. In addition, the residents tampered with the crime scene, waited an inordinate amount of time to call 911, and exhibited strange behavior when paramedics and police arrived. Authorities believe that either some or all of the three house-mates murdered Wone and engaged in a cover-up.
The unidentified body of Lavender Doe was found on 6 October 2006 in Kilgore, Texas. She died shortly before she was found, but was not recognizable because her body had been badly burned.

Paul Quinn, 21, died on 20 October 2007 in Drogheda, Ireland, after being beaten with farm implements by a group of people with such length and severity as to break literally every major bone in his body. It is believed his death was the result of a feud with local IRA members. No suspects have been named.
John Pezzenti, 55, a wildlife photographer, was found shot dead in his Anchorage, Alaska, apartment December 3, 2007. Neither a motive nor a suspect has emerged from the investigation.

She and several other people in the house at the time have been publicly identified as suspects, but not charged.
A worker at a landfill outside Wilmington, Delaware, spotted the body of John P. Wheeler III, 66, founder of the Vietnam Veterans Memorial Fund, contract employee of Mitre Corp., and an official who had served in the Department of Defense under Republican administrations, in some waste being unloaded on December 31, 2010. He had been beaten to death sometime after being seen at an intersection downtown the preceding afternoon; witnesses who had seen him in various locations around Wilmington over the previous two days said he had appeared somewhat confused and disoriented but sober, claiming at one point to have been robbed, but refused offers of help. He was reportedly involved in a feud with a neighbor and may have been involved in an attempted arson; no suspects have emerged.
On the afternoon of September 12, 2011, Brendan Mess, Erik Weissman, and Raphael Teken were found with their throats cut almost to the point of decapitation in different rooms of Mess's Waltham, Massachusetts, apartment, their bodies sprinkled with $5,000 in cash and seven pounds of marijuana, an amount having an even higher street value at the time, suggesting robbery had not been the motive. It was determined that the three had been killed the previous evening. After Tamerlan Tsarnaev was killed by police following the Boston Marathon bombings a year and a half later that his brother Dzhokhar was later convicted of perpetrating, it was disclosed that he had been suspected of involvement in the Waltham murders, due in part to his acquaintanceship with one of the victims. Ibragim Todashev, another friend of Tsarnaev's who had been suspected of involvement, was killed when he reacted violently during an FBI interrogation shortly after the bombings. Police still suspect Dzhokhar, sentenced to death in 2015 for his role in the bombings, of being involved as well, but have not formally charged him.
The person or persons behind the Annecy shootings, in which an Iraqi-born British engineer, several of his family members and a French cyclist were murdered at a campsite in the French Alps on 5 September 2012, have never been identified officially, and the case remains under investigation.
Keith Ratliff, 32, producer of the popular YouTube gun-enthusiast channel FPSRussia, was found dead from a gunshot wound to the head in his custom gun shop in Carnesville, Georgia, on the evening of January 3, 2013, about 24 hours after he had last been seen alive. Police believe he knew his killer, as none of his guns were taken nor used to kill him, and he would have only allowed an acquaintance to get close enough to him to do it. The investigation is continuing.
In the early morning hours of 11 January 2013, Paris police forced their way into a local Kurdish information center, where they found the bodies of Kurdistan Workers' Party (PKK) members Sakine Cansız, 55, Fidan Doğan, 33 and Leyla Söylemez, a younger woman. They had last been seen in the office where they were found the previous afternoon. Nothing had been taken, all were shot execution-style and the killer or killers locked the door after leaving, suggesting that someone acquainted with at least one of the victims committed the crime with the intention of killing all three.
Dan Markel, 41, a law professor at Florida State University, was shot as he pulled into the driveway of his Tallahassee home on July 19, 2014; he died the next day. No suspects have been identified; police are investigating the possibility his death was linked to hostile commentary he had received online.
John Bodkin Adams, a physician suspected of being a serial killer, England. One alleged victim, Gertrude Hullett, was found to have committed suicide at the inquest in 1956, but Dr. Adams was indicted for her murder the following year. The case was then dropped by the prosecution via a nolle prosequi, an action described by the judge as an "abuse of process".
Ottavio Bottecchia, 1927, Italian cyclist, was found by the side of a road, covered with bruises and with a serious skull fracture. His bicycle was undamaged, propped against a nearby tree. He was brought to a hospital but died soon afterwards. An official inquiry concluded accidental death but many suspected that he had run afoul of the powerful and growing fascist movement in Italy at the time.
King Ananda Mahidol of Thailand, 1946. Died of gunshot wounds; suicide, accident or assassination.
Jan Masaryk, 1948, son of Tomáš Garrigue Masaryk; Czech diplomat, politician and Foreign Minister of Czechoslovakia, was found dead in the courtyard of the Foreign Ministry below his bathroom window. The initial investigation concluded that he committed suicide by jumping out of the window, although many are convinced that he was pushed.
Sadanori Shimoyama, 1948, first director of Japanese National Railways, was last definitely seen leaving his official car to go into a department store on his way to work the morning of July 5 of that year. Others reported seeing him at various train stations, and walking along one line, that afternoon. His dismembered body was found at noon the next day on the Jōban Line. It had indisputably gotten that way as a result of being struck by a train, but the autopsy suggested he had died before being struck. That conclusion has been disputed, and whether his death was a suicide or murder remains undetermined.
The Dyatlov Pass incident was the death of nine hikers on the Kholat Syakhl mountain in the northern Ural Mountains range on 2 February 1959; all the bodies were not recovered until that May. While most of the victims were found to have died of hypothermia after apparently abandoning their tent high on an exposed mountainside, two had fractured skulls, two had broken ribs, and one was missing her tongue. After testing, the clothing of some of the victims was found to be highly radioactive. There were no witnesses or survivors to provide any testimony, and the cause of death was listed as a "compelling natural force", most likely an avalanche, by Soviet investigators.
Dr Gilbert Stanley Bogle, 39, and Margaret Olive Chandler, 29, were found dead, both partially undressed, near the banks of the Lane Cove River in Sydney, Australia, on 1 January 1963. Their bluish pallor and the presence of vomit and excrement led to a finding that they had been poisoned, but the coroner was unable to determine at the time what the toxin was, and it was suspected they had been murdered (possibly by Chandler's husband) although no suspects have ever been identified. A 2006 TV documentary, however, has suggested their deaths were not due to foul play but natural, the result of hydrogen sulfide leaking from the river bed and reaching dangerously high concentrations in the air of the low-lying depressions near the river where their bodies were found.
Joan Robinson Hill, 1969, Texas socialite. At first ruled to have died of influenza following a brief hospitalization on March 19, suspicions were aroused when her body was released to the funeral home and embalmed before a legally required autopsy could be carried out. Despite the compromised evidence, three autopsies, all with their own irregularities, were performed and her husband John eventually became the only person indicted by a Texas grand jury for murder by omission, or failing to take proper action in the face of a life-threatening situation. The first attempt to prosecute him ended in a mistrial in 1972; he was murdered before he could be retried and the gunman who was suspected of his murder died in a police shootout. Two other alleged accomplices were later convicted.
Ronald Hughes an American attorney who disappeared while on a camping trip in November 1970. His body was found in March 1971, but his cause of death could not be determined.
Isdal Woman, a partially charred corpse found on November 29, 1970, hidden off a hiking trail near Bergen, Norway. She has never been identified, despite extensive investigation. The official conclusion that her death was a suicide has not been widely accepted.
Nuclear-power whistleblower Karen Silkwood died in a car accident on November 13, 1974, while driving to a meeting with a New York Times reporter in Oklahoma City. Whether that accident involved another vehicle, which may even have deliberately run her off the road, or resulted from her own fatigue has always been a matter of debate.
On November 29, 1981, actress Natalie Wood, who had been boating with her husband Robert Wagner and fellow actor Christopher Walken, was found drowned near Santa Catalina Island, California. While that has always been accepted as the direct cause of her death, the circumstances under which she went into the water have never been clear, and after reopening the investigation in 2012 the coroner changed the cause of death from "accident" to "undetermined", based on cuts and bruises on her body that may or may not have been suffered before her death.
Eduardo Frei Montalva, 1982, president of Chile from 1964 to 1970. As of 2005, his death is being investigated because of allegations that he was poisoned.

Yves Godard and family, 1999. A French doctor who disappeared on board a sailing boat with his two children. Several years later, bones belonging to Dr Godard and his young daughter were discovered in the English Channel. No trace of his son or his wife (the latter did not go on the sailing trip) has ever been found, nor has any trace of the boat. Prosecutors believe Dr Godard probably murdered his family before committing suicide at sea, but they also acknowledge that they cannot be certain of this.
Jonathan Luna, 38, an assistant U.S. attorney from Baltimore, was found dead of multiple stab wounds inflicted with his own penknife in Denver, Pennsylvania, on the morning of December 4, 2003, in a stream underneath his car, which had been driven there overnight from Baltimore. The FBI, which has jurisdiction over the possible murder of any U.S. federal employee, found that Luna had mounting financial problems and was facing an investigation over missing money at his office, considered it a suicide or botched attempt at staging a kidnapping. However, the Lancaster County coroner's office, pointing to evidence suggesting he had been abducted and someone else was driving for at least the final stage of his drive, ruled it a homicide and considers the case open.
On October 4, 2006, the skeletonized remains of Frauke Liebs, 21, a student nurse, were found off a road near Lichtenau, Germany. She had last been seen leaving a bar on June 20, and called her roommate several times in the days afterwards indicating she would come home but being vague about when or how. Police now believe she was being held against her will and might have been murdered, although the body was too decomposed to establish a cause of death.
Barbara Precht's body was found on 29 November 2006 in Cincinnati, Ohio. She remained unidentified until November 2014. Her husband was located later on and is considered a person of interest in her death, which has unknown circumstances.
Joyce Carol Vincent, 38, was found dead in her London flat in December 2006, three years after she had died, by which time the body had decomposed so much as to make identifying a cause of death impossible; her story was profiled in the 2011 documentary Dreams of a Life.
Two-year-old Caylee Anthony, of Orlando, Florida, was reported missing by her grandmother in the summer of 2008, when she learned that her daughter Casey hadn't seen her in over a month. Casey claimed the girl had been kidnapped by someone no one else but she had ever met, and circumstantial evidence led to her arrest on murder charges that fall. A tip that could have led to the body's discovery in August was not fully acted upon until December; by then the body was so decomposed that it was impossible to establish how Caylee had died, although the coroner ruled it homicide. Casey Anthony, despite public sentiment strongly against her, was acquitted of the murder and child-abuse charges (but convicted of the lesser charges of lying to the police) after a heavily covered trial in 2011, where her lawyer claimed that Caylee had accidentally drowned in the family pool and Casey's domineering father had led a coverup.
Bob Woolmer, Pakistan's coach found dead in his hotel room after losing in the Cricket World Cup 2007 in the West Indies. Investigators at first ruled the death a suicide, but the jury that heard the inquest was not so sure and returned an open verdict.
Skeletal remains found in a dry creek bed in California's Malibu Canyon on August 9, 2010, turned out to be those of Mitrice Richardson, 25, who had last been seen on the night of the previous September 16 in the backyard of a former local television news anchor, after being arrested for marijuana possession and failure to pay the bill at a local restaurant where she had been acting strangely, behavior that investigating officers did not believe was caused by alcohol or drugs. While the coroner has said her death did not appear to be a homicide, the body was too decayed to determine the exact cause of death.
On 23 August 2010, the partially decomposed body of Gareth Williams, 32, a Welsh mathematician who worked for British intelligence GCHQ, but who was seconded to MI6 at the time of his death, was found in a padlocked bag in the bathroom of a safe house in the London neighborhood of Pimlico. It was determined he had been dead for about a week. Due to the nature of his work, the investigation had to withhold details of it and some other aspects from any material made public; his family and friends allege that the Metropolitan Police compromised and mishandled key forensic evidence in the early stages of their response. An initial investigation by the coroner's office concluded that the death was a homicide; a later re-investigation by the police claimed that it was instead an accident.
On November 15–16, 2013, skeletal remains of two adults and child were found in a field outside Red Oak, Oklahoma. A year later they were identified as the Jamison family, who had gone missing in 2009 while looking into some land they wanted to purchase. Their abandoned pickup truck was three miles (4.8 km) from where their bodies were found. No cause of death has been determined.
On June 27, 2014, the body of 20-year-old Andrew Sadek was recovered from the Red River near Breckenridge, Minnesota, with a small-caliber gunshot wound and a backpack full of rocks. He had last been seen by a security camera leaving his dorm at North Dakota State College of Science in Wahpeton around 2 a.m. on May 1. At the time of his disappearance he had been working as a confidential informant for local police as a result of his own arrest for selling marijuana on campus, which could otherwise have resulted in a long prison sentence. It has not been determined yet whether his death was suicide or murder. Like Rachel Hoffman's death, the case has been used as an example of the mishandling of youthful CIs by police.
Alberto Nisman, 51, an Argentine federal prosecutor, was found dead in his apartment of a single gunshot wound to the head on January 18, 2015. He had been investigating the 1994 AMIA bombing, Argentina's deadliest terror attack, and had publicly accused President Cristina Kirchner and other high officials close to her of covering up for suspects in the case for foreign-policy reasons; he was scheduled to present these allegations to Congress the next day. While some of the circumstances of his death are consistent with an early statement that he committed suicide, friends and relatives say that he was eagerly looking ahead to his appearance before Congress and did not seem depressed or despondent at all. Kirchner has suggested the country's intelligence services were behind the killing, since he was about to expose their attempts to bring her down, and called for them to be dismantled. The case remains under investigation.
Raoul Wallenberg, a Swedish humanitarian who worked in Budapest, Hungary, was most likely executed in Russia in or around 1947 after being captured by the Red Army in 1945. His death is dated by Soviet authorities as 16 July 1947, but this is disputed, and the case remains unsolved.
