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.)
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 tried and acquitted in the ensuing years.
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 July 25, 1879.
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.
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.
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 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 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 but doubted.
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.
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.
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.
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 about 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 Bonnano family, seen fleeing the scene, who had likely acted on the orders of a Bonnano 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.

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.
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.
Liaquat Ali Khan: On 16 October 1951, Khan was shot twice in the chest during a public meeting of the Muslim City League at Company Bagh (Company Gardens), Rawalpindi. The police immediately shot the assassin who was later identified as Saad Akbar Babrak. Khan was rushed to a hospital and given a blood transfusion, but he succumbed to his injuries. The exact motive behind the assassination has never been fully revealed. Saad Akbar Babrak was an Afghan national and a professional assassin from Hazara. He was known to the police prior to the assassination of Liaquat Ali Khan. The assassination is still a questionable because it was never investigated properly.
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.
Evelyn Hartley,15, from La Crosse, Wisconsin, was babysitting for Professor Viggo Rasmusen on the evening of October 24, 1953 when she was kidnapped. That was the night of the La Crosse football game and attendance was high. There were signs of a struggle in the living room where her broken glasses were left. In the basement there was blood and an open window where the kidnapper came in and took Evelyn out. Though her body was never found, weeks later bloody undergarments resembling hers were discovered on Highway 14, two miles south of La Crosse. There was a fifteen-minute window between the Rasmusens's leaving and her disappearance.

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.
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.
Geneva "Jean" Hilliker Ellroy, a 43-year-old divorced nurse, was found strangled to death near Arroyo High School in El Monte, California on 22 June 1958. No promising suspects were ever produced, though she was seen with an unknown man and woman in the hours before her death. The case received only superficial notice from the media, possibly due to the recent homicide of Johnny Stompanato. The victim's ten-year-old son James Ellroy, (then Lee Earle Ellroy), would become a bestselling crime novelist later in life and would revisit his mother's murder in his 1996 memoir, My Dark Places.
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.

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.
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.

Shot to death on 12 October 1964 by an unknown assailant after finishing a painting and going for a walk.

Dorothy Kilgallen, 1965, New York City, death certificate reads "acute ethanol and barbiturate intoxication / circumstances undetermined." People who have said publicly that she could have been murdered (perhaps by needle injection after drinking an unknown amount of alcohol) include Larry King, Dominick Dunne, Bob Bach, who booked the mystery guests on Kilgallen's TV show What's My Line?, and Manhattan-based magazine writer and novelist Mary Brannum Bringle. Bringle was a colleague of Patricia Bosworth at Screen Stars magazine in 1965 when a strange anonymous phone call reached the magazine's office and the male phone caller informed Bringle that Dorothy Kilgallen had been murdered.
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.
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 exited 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 immediately realized that she had been stabbed.
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.

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. Later that same year, on November 3, Frances Bemis, a socialite friend of Lindsley's who had reportedly been conducting her own investigation of the murder, was found with her skull crushed in the neighborhood. That case also remains unsolved.

She had been beaten and sexually assaulted before her death but not raped; an ice pick found lodged into the base of her skull during the autopsy turned out to be the murder weapon. David Berkowitz, the "Son of Sam" serial killer, told investigators he had heard details about the killing from another inmate purportedly linked to the Manson family, but they ultimately discounted his information. No other suspects have ever been identified.
Betty van Patter, 52, bookkeeper for the Black Panther Party, was last seen leaving a San Francisco tavern on December 13, 1974.

However, no charges have ever been brought in the case.
Barbara Colby, an American actress from Venice, California, United States, was shot to death while walking with a colleague to his car on 24 July 1975. She died instantly from her wounds but her colleague was able to describe the shooting to the police before he also died from his wounds. He said the shooting occurred without reason or provocation and said that there were two gunmen whom he did not recognize. There was no attempt at robbery, and the killers and their motivation are still unknown.
A bomb went off on the evening of December 29, 1975, at the TWA baggage claim at New York's LaGuardia Airport, killing 11.

Officially it remains unsolved.
Jim Leslie, 38, a publicist and lobbyist for the government of Shreveport, Louisiana, was shot fatally in the parking lot of a Baton Rouge hotel July 9, 1976, on his way to celebrate a legislative victory.

Crane had allegedly called his friend John Henry Carpenter the night before to tell him their friendship was over. Crane was involved in the underground sexual scene and filmed his numerous escapades with the help of Carpenter, who was an audio-visual expert. Police reportedly found blood smears in Carpenter's car that matched Crane's blood type, but no charges were filed against Carpenter for more than a decade. When he was charged in 1994, he was acquitted. Carpenter maintained his innocence until his death in 1998, and the case is now officially cold.
Raymond Washington, original founder of the notorious South Central Los Angeles street gang that came to be known as the Crips was murdered on August 9, 1979. Washington was shot dead at the age of 25 when he walked up to a car on the corner of 64th and San Pedro Streets in Los Angeles.

Grégory Villemin, a 4-year-old boy in Lépanges-sur-Vologne, France, disappeared from the sandbox in front of his house on October 16, 1984, and was found in the Vologne river nearby several hours later, although the evidence later suggested he had been drowned somewhere else and placed in the river. His father later fatally shot a relative initially suspected of the killing due to a series of anonymous notes sent to various people in town, and his mother was tried for the offense in a pair of trials that became an international media sensation. She was acquitted, and the case remains open and unsolved.
Christine Jessop, an eight-year-old girl of Queensville, Ontario, was raped and murdered in October 1984. Her next-door neighbour, Guy Paul Morin, was wrongly convicted of the crime in 1992 but DNA testing led to a subsequent overturning of this verdict in 1995.

Two, Robert and Rochelle Manning, who were suspects in other bombings believed to have been carried out by the group, have been tried in American courts. After a mistrial in her case, Rochelle Manning went to Israel to join her husband, who was extradited in 1993 and convicted of one of the other bombings; he is currently serving a life sentence. Another suspect, already in prison, agreed to cooperate but was killed by a fellow inmate shortly thereafter. The FBI continues to pursue the extradition of the other JDL members who are believed to be living in the West Bank settlement of Kiryat Arba.

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.

Her body was later discovered in a ravine near Crofton, Nebraska not far from the party she attended the night of September 17, 1992. The case eventually went to trial years later and the primary suspect Eric Stukel was acquitted of class III felony manslaughter. It is believed the acquittal was partially due to a Nebraska law requiring the prosecution to prove the victim actually died within Cedar County. Eric Stukel maintains his innocence, and no others have come forward with information that could lead to an arrest.

On Nov. 10, 1993, Seann Campbell and Bryan Benson, both 20, were stabbed to death at a West Coast Video store in the Philadelphia suburb of Warminster. The boys were attacked as they were closing the shop for the night. They had been stabbed repeatedly in the chest and neck, their bodies discovered the next morning. One major clue, a bloody earring apparently ripped from the ear of an assailant, has never helped police find the killer. $300 was taken from the store, but money was left in the register and the boys' wallets were not taken. Police believed the boys were killed by one or more persons using a long-bladed knife. Many suspects have been developed by police over the years, including a serial killer who was known to be in the area at the time. There was no evidence of forced entry and no motive has ever been established. This is considered the most notorious unsolved murder in Bucks County, Pennsylvania.

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.

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.
On 20 September 1987, the Dana Point Jane Doe was found at the bottom of a cliff in Dana Point, California. Her death was ruled a suicide but some speculate she may have been pushed. She has never been identified.
Uwe Barschel, 43, minister-president of Schleswig-Holstein, was found dead in his hotel bathroom, fully dressed in a full tub of water, on 11 October 1987. The cause of death has never been conclusively established.
Zviad Gamsakhurdia, 1993, former president of Georgia, died in circumstances that were (and still are) very unclear. It is known that he died in the village of Khibula in the Samegrelo region of western Georgia.
Gary Kildall, 1994, computing pioneer and developer of the CP/M operating system. While blunt force trauma indisputably led to his death, it has never been established whether that injury resulted from an accidental fall or an assault.
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.
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 against her (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.
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. Death is dated by Soviet authorities as 16 July 1947, but this is disputed; remains an unsolved case.
