List of serial killers by number of victims

From Wikipedia, the free encyclopedia
Jump to navigation Jump to search

A serial killer is typically a person who murders three or more people, in two or more separate events over a period of time, for primarily psychological reasons.[1][2] There are gaps of time between the killings, which may range from a few days to months, or many years.[2] This list shows serial killers from the 20th century to present day by number of victims. In many cases, the exact number of victims assigned to a serial killer is not known, and even if that person is convicted of a few, there can be the possibility that they killed many more.

Organization and ranking of serial killings is made difficult by the complex nature of serial killers, and incomplete knowledge of the full extent of many killers' crimes. To address this, multiple categories have been provided in order to more accurately describe the nature of certain serial murders. This is not a reflection of an individual's overall rank, which may or may not vary depending on personal opinion concerning the nature and circumstances of their crimes. The fourth column in the table states the number of victims definitely assigned to that particular serial killer, and thus the table is in order of that figure. The fifth column states the number of possible victims the killer could have murdered. Some of these crimes are unsolved, but were included because they are the work of a serial killer, despite nobody being caught.

This list does not necessarily include war criminals or members of democidal governments, such as Adolf Hitler, Hideki Tojo, Mao Zedong, Vladimir Lenin, Joseph Stalin, or Pol Pot.

Serial killers with the highest known victim count

The most prolific modern serial killer is Harold Shipman, with 218 proven kills and possibly as many as 250 (see "Medical professionals", below). Excluding these "Medical professionals and pseudo-medical professionals", with their ability to kill simply and in plain sight, and Serial killer groups and couples (below), this list is a compilation of modern serial killers currently with the highest verifiable murder count.

Thugs used to rob people in travelling caravans by deceitfully joining them as fellow travelers. During the night, the thugs would kill them by strangling them with a rumal (hankerchief). Behram wore his sturdy rumal as a kamarbandh(belt). A large medallion was sewn inside. Exerting pressure on the adam's apple it would give a slow, painful but effective death.

Javed Iqbal  Pakistan 1996 to 1999 74+ 100+ He raped, strangled and put acid in several children. Arrested, he claimed 100 victims. He was found guilty of 100 killings but 26 children were found alive after he hanged himself in prison.[776]

 Nazi Germany
1928 to 1943 51 86 Mentally disabled, Lüdke was arrested after being discovered with a corpse.

Fernando Hernández Leyva  Mexico 1982? to 1999 33 100–137 Confessed to 100 murders and six kidnappings at the time of his arrest in 1999 (he had been arrested previously in 1982 and 1986, the second time for murder, but escaped from prison), but later retracted and claimed that he had been beaten by the police and his family threatened in order to force him to confess.

"Highway of Tears" Killer  Canada 1969 to 2011 18 43 All the victims were young women and were last seen on Highway 16 in British Columbia between Prince George and Prince Rupert. If they were all victims of the same person, it would be one of the most proficient serial killers in Canada and one with the longest careers in the world. Some of the murders have been linked to American criminal Bobby Jack Fowler, although he was in prison at the time others were committed.[781]
The Stoneman  India 1985 to 1989 12–25 12 homeless people were murdered in their sleep in Bombay between 1985 and 1987, and 13 in Calcutta in 1989; in all cases, by dropping a large rock over their head (an additional victim escaped, but could not identify the attacker).

Some included dismemberment, necrophilia, even cannibalism. Lawmen linked the Lucas and Otis Toole to 81 murders alone. Convicted of 11 murders.[784] The true number of murders committed by Lucas is unknown, but it is likely Lucas was not nearly as prolific a serial killer as he initially claimed to be, as most of his murder confessions were thoroughly discredited, and he himself claimed only one murder—that of his mother.[785][786][787] Probably responsible for the deaths of 40 people.[788]
Charles Quansah  Ghana 1993 to 2001 8 34 Quansah, who had been in prison for rape twice, was held as a suspect in the deaths of 34 women across the country, including his girlfriend who was strangled in 2000, and eventually confessed to eight murders. He later denied the killings, claiming that the confessions had been extracted under torture, and that the police had also tried unsuccessfully to force him to implicate a number of politicians including former president Jerry Rawlings, his wife Nana Konadu Agyeman and an unidentified member of president John Kufuor's administration.[789][790]

Ottis Toole  United States 1980 to 1983 7 8–125 Initially convicted of three counts of murder, later pleading guilty to four more murders before dying in prison. A sometime accomplice of convicted serial killer Henry Lee Lucas, Toole admitted to—and retracted multiple times—over a hundred counts of murder, rape, arson and cannibalism, and was the suspect in several other unsolved murders. On December 16, 2008, police announced that they had identified Toole as the likely murderer of Adam Walsh, and would be closing the case as a result.[793]
The Beer Man  India 2006 to 2007 7 Purported unidentified serial killer that operated in Mumbai and left a beer bottle next to each body as his signature, hence the nickname. A suspect was charged with three of the murders and convicted of one in 2008, but the sentence was overturned by the High Court in 2009 because the evidence presented was deemed inadmissible.[794]

Wayne Williams  United States 1979 to 1981 2 24-31 Believed to have perpetrated the Atlanta murders of 1979–1981.

Joe Ball  United States 1937 to 1938 2 20 Bootlegger and barman known as the "Butcher of Elmendorf", the "Bluebeard of South Texas", and "the Alligator Man" because of the alligator pit he had in the back of his bar and where he entertained clients by throwing live animals to the reptiles. Ball killed for sure two barmaids whose bodies were dug and later discovered at the beach, but he shot himself fatally in the chest when police came to question him and was never arrested or interrogated. Yellow press and pulp magazines later exaggerated his exploits, claiming that he had killed up to 20 women and fed them to the alligators, but this was never proven and caused some of Ball's relatives to sue such publications. Police investigated about a dozen women that had worked at Ball's place and were missing at the time of his suicide; some were found alive in San Antonio, but others could not be accounted for.[799]
Abdul Latif Sharif  Mexico 1995 1 18–20 Egyptian chemist known as "The Jackal of Ciudad Juárez".

There, he was accused of up to 20 of the female homicides in Ciudad Juárez but was convicted of only one, to 30 years in prison, where he died of natural causes in 2006. As the high rate of female murders has continued to this day in Ciudad Juárez, it has been claimed that Sharif was used as a scapegoat by the Mexican police.[800]

Bevan Spencer von Einem  Australia 1979? to 1983 1 3–10 Arrested for three and convicted of one of "The Family Murders", where four teenagers and one young adult, all male, were drugged, kidnapped, raped and mutilated for weeks before their bodies were abandoned in the country near Adelaide. Police believed that von Einem had several accomplices, none of whom were publicly identified or detained, and at the time of his trial it was widely reported that the murders had been committed by a group of 4 to 12 high-profile Australian men; von Einem himself claimed to be the victim of a conspiracy. He has also been considered a suspect in the disappearance of two girls near the Adelaide Oval in 1973 and the high-profile Beaumont children disappearance in 1966.[803]
John Bodkin Adams  United Kingdom 1946 to 1956 0 163 Acquitted in a highly unusual trial in 1957 of murder but later found guilty of fraud. Archive evidence shows that he was almost certainly a killer but that his prosecution was botched for political reasons.[804]

However, all of his proven victims there were rescued before he could kill them, and he was recluded in a mental hospital from 1977 to 1991. Released to his mother in Montana, he was later suspected of killing a child and serving his flesh to his unwitting family and neighbors. Although human remains belonging to two different people were found in a meat grinder in his kitchen and buried under one of his former residences, no murders could be conclusively proven and these charges were dropped. Instead, Bar-Jonah was tried for unrelated molestation and torture of three children and convicted to 130 years in prison without parole. He died in prison in 2008.[815]
