List of serial killers by number of victims
Updated: 11/5/2025, 10:01:33 AM Wikipedia source
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. There are gaps of time between the killings, which may range from a few days to months, or many years. This list shows all known serial killers from the 20th century to present day by number of victims, then possible victims, then date. For those from previous centuries, see List of serial killers before 1900. 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 are included because they are the work of a serial killer, despite nobody being caught. This list does not include mass murderers, spree killers, war criminals, members of democidal governments, or major political figures, such as Adolf Hitler, Francisco Franco, Hideki Tojo, Suharto, Mao Zedong, Joseph Stalin, or Pol Pot.

Unidentified killer who shot couples in lovers lanes and mutilated the women, taking their sexual organs and in the last two cases, also their left breast. 69-year-old farmer Pietro Pacciani was controversially convicted of 14 crimes in 1994 and sentenced to life in prison, but he was released following allegations that the scant evidence had been planted in an attempt to close the case, which was by then the largest and most mediatic in Italy's criminal history. Pacciani was scheduled for retrial in 1998 when he died after taking medication contraindicated to his heart problems. Pacciani's two alleged accomplices, Mario Vanni and Giancarlo Lotti, were sentenced to life and 30 years in prison, respectively. Some believe that none of the accused were guilty, and that Lotti incriminated himself and the other two because he was homeless and wanted to live in prison.

Notes
Killed at least 13 women between 30 October 1975 and 17 November 1980. Most victims were killed by a combination of bludgeoning and stabbing, and all but two were killed in the county of Yorkshire. Owing to the modus operandi and location of the murders, Sutcliffe became known as the "Yorkshire Ripper". Sentenced to 20 concurrent life sentences. After three years he was sent to a secure psychiatric facility, where he served 25 years before being found "fit to leave" in 2009. Government officials and courts ruled in 2010 that he would never be released. In 2015, he was declared "no longer mentally ill", and transferred to a maximum security prison. After his 1981 conviction police investigated 60 unsolved murders and attempted murders across Britain they thought Sutcliffe could be responsible for, but were able to eliminate him from 40. He has since also been linked by several investigators to the murder of Carol Wilkinson, for which an innocent man spent many years in prison. Sutcliffe died in hospital on 13 November 2020 at age 74, after being diagnosed with COVID-19.

| Name | Country | Years active | Proven victims | Possible victims | Notes |
| Carl Eugene Watts | United States | 1974–1982 | 14 | 100+ | Believed to have killed over 80 women in multiple states, in 1982 Watts accepted a plea bargain in Texas in which he would plead guilty to a lesser charge and be granted immunity from murder charges in exchange for providing information on his victims; as a result he confessed to 12 murders and was sentenced to 60 years in prison on the lesser charge. He was sentenced to life imprisonment in separate trials in Michigan in 2004 and 2007, and died of cancer a week after the 2007 sentence was handed down. Watts is now suspected to have killed more than 100 women, which would make him the most prolific serial killer in American history. |
| Belle Gunness | United States | 1884–1908 | 14 | 40 | Norwegian-born murder-for-profit killer who murdered her suitors and relatives in Indiana. High possibility of committing over 40 murders. May have faked her own death in the fire that destroyed her home in 1908; her children had died of strychnine poisoning before the fire, and the woman's body found next to them was decapitated and, reportedly, smaller than Gunness' own. Ultimate fate unknown. |

Pacciani was scheduled for retrial in 1998 when he died after taking medication contraindicated to his heart problems. Pacciani's two alleged accomplices, Mario Vanni and Giancarlo Lotti, were sentenced to life and 30 years in prison, respectively. Some believe that none of the accused were guilty, and that Lotti incriminated himself and the other two because he was homeless and wanted to live in prison. |

| Peter Sutcliffe | United Kingdom | 1975–1980 | 13 | 33 | Killed at least 13 women between 30 October 1975 and 17 November 1980. Most victims were killed by a combination of bludgeoning and stabbing, and all but two were killed in the county of Yorkshire. Owing to the modus operandi and location of the murders, Sutcliffe became known as the "Yorkshire Ripper". Sentenced to 20 concurrent life sentences. After three years he was sent to a secure psychiatric facility, where he served 25 years before being found "fit to leave" in 2009.

Killed himself by hanging after murdering his wife and niece. The latter was also decapitated and eviscerated in a manner strongly similar to 26 unsolved murders of women in Florida, starting in 1973, the year Brandt moved to the state. Brandt was later considered the culprit in one of these murders, due to his strong resemblance to a suspect who was filmed by a traffic camera near the place where one body was found. He could not be officially tied to the other crimes due to lack of evidence. Previously, when he was 13 years old in 1971, he attempted to murder his whole family with a gun, for no apparent reason. His mother (who was pregnant) died in this attack, but his father survived, and his sister escaped.

Notes
A skilled forger who, while he ran a legitimate business buying and selling organic beef, primarily enriched himself by passing bad checks on the accounts of others and using forged documents; by 2003 he had faced criminal charges in four Western states. These white-collar crimes also enabled his murders, by allowing him to create evidence that his victims were still alive after he had killed them; he also used their checking accounts and credit cards to further his schemes once they were dead. For the first year of his murder activity, he worked as an informant for the FBI, which both paid him and protected him from facing justice over some of his fraud schemes.

The earliest homicide Rogers is suspected of is that of an elderly Ohio man, Mark Peters, with whom Rogers had lived for a short time.

| Alexander Spesivtsev | Russia | 1991–1996 | 4 | 82+ | Cannibal known as "The Novokuznetsk Monster"; admitted to 19 murders, but 82 bloody sets of clothes were found in his home, along with jewels and photographs of possibly unidentified victims. Found insane and interned in a mental hospital. His mother was sentenced to 16 years in prison for luring Spesivtsev's victims to their home. |
| Charlie Brandt | United States | 1971–2004 | 4 | 29 | Killed himself by hanging after murdering his wife and niece. The latter was also decapitated and eviscerated in a manner strongly similar to 26 unsolved murders of women in Florida, starting in 1973, the year Brandt moved to the state. Brandt was later considered the culprit in one of these murders, due to his strong resemblance to a suspect who was filmed by a traffic camera near the place where one body was found. He could not be officially tied to the other crimes due to lack of evidence. Previously, when he was 13 years old in 1971, he attempted to murder his whole family with a gun, for no apparent reason. His mother (who was pregnant) died in this attack, but his father survived, and his sister escaped. |
| Scott Lee Kimball | United States | 2003–2004 | 4 | 21 | A skilled forger who, while he ran a legitimate business buying and selling organic beef, primarily enriched himself by passing bad checks on the accounts of others and using forged documents; by 2003 he had faced criminal charges in four Western states. These white-collar crimes also enabled his murders, by allowing him to create evidence that his victims were still alive after he had killed them; he also used their checking accounts and credit cards to further his schemes once they were dead. For the first year of his murder activity, he worked as an informant for the FBI, which both paid him and protected him from facing justice over some of his fraud schemes. |

Some included dismemberment, necrophilia, even cannibalism. Lawmen linked Lucas and Ottis Toole to 81 murders only. Convicted of 11 murders. 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.

British nurse who was convicted in 1974 of the murder of a patient with insulin after being inspired by the plot of A Man Called Ironside. She was released on appeal in 1975, despite three appeal court judges saying there was ample evidence to support the conviction, as the trial judge had inadvertently misled the jury in his final summary. The appeal court judges said that it was an omission that "a few words could have cured". Apart from the case prosecuted, another 23 cases were deemed suspicious by investigators. Although acquitted, McTavish's case often is mentioned in lectures at medical colleges in Britain, and is cited in textbooks and academic papers about forensic science and medical malpractice. McTavish, now known as Jessie Gordon, is believed to have been the inspiration for serial killer nurse Colin Norris.

| Name | Country | Years active | Proven victims | Possible victims | Notes |
| Bruno Lüdke | Germany | 1928–1943 | 51 | 86 | Mentally disabled, Lüdke was arrested after being discovered with a corpse. Police declared him insane and imprisoned him in a psychiatric hospital, where he died when he was experimented on. The only evidence tying him to the crimes was a confession that may have been physically coerced. He was never given a trial and he is generally considered innocent. |
| "Highway of Tears" Killer | Canada | 1980–present | 18 | 83 | 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 prolific serial killers in Canada and one with the longest career 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. |
| Orlando Sabino | Brazil | 1966?–1971? | 12 | Suspected of murdering 12 people in Minas Gerais and Goiás, as well as mutilating several animals; sentenced to 38 years' imprisonment and died from a heart attack in 2013. Conspiracy theorists allege that the victims were killed by the military government, which framed Sabino. | |
| Charles Quansah | Ghana | 1993–2001 | 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. |
| Redhead murders | United States | 1978–1992 | 8+ | Series of unsolved homicides believed to have been committed by an unidentified serial killer in Tennessee, Arkansas, Kentucky, Mississippi and Pennsylvania. | |
| Jeff Davis 8 | United States | 2005–2009 | 8 | The bodies of eight women, all of whom had an involvement with drugs or prostitution, were found in swamps and canals surrounding Jennings, Louisiana. Originally thought to be a serial killer, but multiple suspects may be involved. | |
| The Beer Man | India | 2006–2007 | 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. | |
| Pedro Rosa da Conceição | Brazil | 1904–1911 | 5 | 17 | Brazilian mass murderer who killed three people and wounded thirteen others on 22 April 1904. Killed his cellmate and a guard in 1911, and is said to have murdered a family of twelve people in an unspecified date and year. Died in 1919. The family murders are not verified. |
| Earl Bramblett | United States | 1977–1994 | 4 | 6 | Mass murderer who murdered four members of the Hodges family in their home in Vinton, Virginia in August 1994. He was a suspect in the 1977 disappearances of Tammy Akers and Angela Rader, who were both 14 years old and worked for him at the time, but not enough evidence to charge him was found before his execution for the Hodges murders in 2003. |
| Henry Lee Lucas | United States | 1960–1983 | 3 | 600+ | Confessed to killing 3,000 and later 600 people but later recanted and is suspected of lying about a majority of the murders. He originally offered a list of 77 women from 19 different states, but as he confessed to more and more murders, the details became increasingly more bizarre. Some included dismemberment, necrophilia, even cannibalism. Lawmen linked Lucas and Ottis Toole to 81 murders only. Convicted of 11 murders. 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. |
| José Pedro Guedes | Portugal | 1992–1993 | 3 | 3–21+ | Confessed and was arrested for the "Lisbon Ripper" murders in 2011, but could not be prosecuted because the Portuguese statute of limitations had already run out. Also suspected of similar murders in Lisbon and Aveiro, Portugal, as well as Germany, the Netherlands, Belgium, Denmark, Czech Republic and the 1988 New Bedford Highway Killings in Massachusetts, USA. |
| "Bowraville Murders" Killer | Australia | 1990–1991 | 3 | Proposed serial killer responsible of the murders of three Aboriginal children in the same area, all bludgeoned to death. Thomas Jay Hart was tried for one of the murders and acquitted, and held as a suspect in another for which he did not face prosecution. | |
| Wayne Williams | United States | 1979–1981 | 2 | 24–31 | Believed to have perpetrated the Atlanta murders of 1979–1981. After being convicted of two murders and sentenced to life imprisonment, authorities closed 22 other unsolved murders, declaring Williams to have been the perpetrator. Williams has maintained his innocence and the case was reopened in 2005. |
| Kieran Patrick Kelly | United Kingdom | c. 1953–1983 | 2 | 31 | Irish vagrant who operated in London, England. He was convicted of two murders but confessed to many more, claiming he used a variety of methods from pushing people in front of trains to setting them on fire to poisoning them, and said he had been murdering for a period of some thirty years. In 2015 former detective George Platt published a book about Kelly claiming he could be responsible for 31 murders, prompting the chief of the Metropolitan Police Bernard Hogan Howe to promise a re-investigation into his crimes. However, in 2019 Irish journalist Robert Mullhern published a book raising serious questions about Platt's claims, concluding that Kelly was only responsible for 5 or 6 murders. |
| Christopher Halliwell | United Kingdom | 1985–2011 | 2 | 28–60 | Halliwell pleaded guilty in 2012 to abducting and murdering Sian O'Callaghan the previous year. He also confessed to the 2003 murder of Becky Godden-Edwards, but his confession was ruled inadmissible and he could not be convicted until 2016, when new evidence was found. Halliwell is a person of interest in 26 other murders, and a collection of articles of women's clothing which included some taken from his victims may link him to up to 60 murders. |
| Allan Grimson | United Kingdom | 1986–1998 | 2 | 22 | Homosexual Royal Navy sailor Grimson was convicted of the partially sexually motivated murders of two other (non-homosexual) Royal Navy sailors while docked in Portsmouth on 12 December 1997 and 12 December 1998. Strongly suspected of being responsible for up to 20 other murders across different navy bases of the world, including in Gibraltar and New Zealand. Also the prime suspect in the disappearance of fellow Royal Navy sailor Simon Parkes from Gibraltar in 1986, in part because he disappeared on 12 December, the date on which Grimson was known to have always killed his victims, and because Grimson was docked in Gibraltar with the navy at this time. Grimson's 2001 trial judge told him that he was "a serial killer in nature if not in number". |
| Billy Edwin Reid | United States | 1989 | 2 | 21 | Reid was arrested in 2006 after a successful DNA profiling test proved his responsibility in the murders of two sex workers in 1989 in Denver, Colorado. It is thought he might have been responsible for many murders, including some from the Denver Prostitute Killer – an unidentified single, or multiple serial killers responsible 17–27 murders between 1975 and 1995. |
| Joe Ball | United States | 1937–1938 | 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 two barmaids 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 missing women who had worked at Ball's place; some were found alive in San Antonio, but others could not be accounted for. |
| Alun Kyte | United Kingdom | 1984–1997 | 2 | 12 | Kyte was found guilty of raping and murdering two sex workers in 1993 and 1994. He reportedly boasted to fellow inmates while serving time on a rape charge that he had killed a total of 12 women and police have linked him to a number of unsolved murders of women although he has been ruled out in many cases in which he was initially suspected. |
| Larry Gene Bell | United States | 1975–1985 | 2 | 5 | Bell abducted and killed two women, Shari Smith and Debra Helmick, in May and June 1985. He was also a suspect in the disappearances of Denise Porch, Sandee Cornett and Beth Hagen. Bell was executed for murdering Smith and Helmick in 1996. |
| Michael Stone | United Kingdom | 1976–1996 | 2 | 4 | Stone, who was convicted of the 1996 double murder of Lin and Megan Russell, is suspected of two other murders. His conviction is controversial and his legal team blame confirmed serial killer Levi Bellfield for the 1996 murders, although members of Stone's family believe he committed one additional murder. |
| David Smith | United Kingdom | 1988–1999 | 2 | 4 | Smith was jailed for life in 1999 for murdering prostitute Amanda Walker. It was widely reported that he had previously been acquitted of the "almost identical" murder of another prostitute, Sarah Crump. Smith's acquittal was overturned in 2023 and he was found guilty of murdering Crump after he bragged to fellow inmates about how he had "got away with it". Smith is also suspected of murdering two other women prior to his initial conviction. |
| James Otto Earhart | United States | 1981–1987 | 2 | 3 | Earhart murdered Virginia Freeman in Brazos County, Texas on 1 December 1981. He also murdered nine-year-old Kandy Kirtland in 1987, and was executed for the murder in 1999. Posthumous DNA testing later proved that he was responsible for Freeman's murder, and he is also suspected of killing another woman in 1986. |
| Jeffrey Willis | United States | 1996–2014 | 2 | 3 | Willis was convicted of the 2013 murder of Jessica Heeringa, whose body was never found, and of the 2014 murder of Rebekah Bletsch. Both women had had their photos included in a file on Willis' computer labelled "vics" (short for victims). Willis is also a person of interest in the unsolved murder of Angela Thornburg in 1996. |
| Ángel Nieves Díaz | United States Puerto Rico | 1978–1979 | 2 | 3 | Díaz was convicted of killing a store clerk in a robbery in Miami in 1979, having escaped from prison in Puerto Rico the previous year after being convicted of murdering another man. Police also suspected him of involvement in a third murder committed while he was on the run. |
| Pam Hupp | United States | 2011–2016 | 1–2 | 3 | Hupp is the prime suspect in the 2011 murder of cancer patient Betsy Faria, who was stabbed to death shortly after making Hupp the sole beneficiary of a sizable life insurance policy. Faria's husband Russ was wrongfully convicted of her murder but was exonerated in 2015 and mobile data placed Hupp at the scene of the crime. After Russ was released, Hupp murdered a man named Louis Gumpenberger in 2016 and attempted to frame Russ for hiring him to kill her, but was caught and sentenced to life imprisonment for the murder. Hupp is currently awaiting trial for the murder of Betsy Faria, and is also suspected of having murdered her mother Shirley Neumann for inheritance in 2013. |
| Clementine Barnabet | United States | 1911 | 1 | 35 | Barnabet was convicted of one murder but confessed as a total of 35. She was believed to have murdered entire families in their sleep, but doubt has been cast on the extent of her involvement. Sentenced to life imprisonment but released in 1923. |
| Jessie McTavish | United Kingdom | 1974 | 1 | 24 | British nurse who was convicted in 1974 of the murder of a patient with insulin after being inspired by the plot of A Man Called Ironside. She was released on appeal in 1975, despite three appeal court judges saying there was ample evidence to support the conviction, as the trial judge had inadvertently misled the jury in his final summary. The appeal court judges said that it was an omission that "a few words could have cured". Apart from the case prosecuted, another 23 cases were deemed suspicious by investigators. Although acquitted, McTavish's case often is mentioned in lectures at medical colleges in Britain, and is cited in textbooks and academic papers about forensic science and medical malpractice. McTavish, now known as Jessie Gordon, is believed to have been the inspiration for serial killer nurse Colin Norris. |
| Abdul Latif Sharif | Mexico | 1995 | 1 | 18–20 | Egyptian chemist known as "The Jackal of Ciudad Juárez". After migrating to the United States in the 1970s, Sharif served 14 years in prison for several rapes but fled to Mexico when he was about to be deported to his home country. 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. |
| Daisuke Mori | Japan | 2000 and earlier | 1 | 11+ | Nurse that was sentenced to life imprisonment for one murder but suspected of killing at least 10 others. He might have confessed to some of the murders in order to protect others. |
| Thomas Henry McMonigle | United States | 1945 and before | 1 | 11 | McMonigle was executed in 1948 for the murder of Thora Afton Chamberlain three years before, having admitted to shooting her and throwing her off a cliff after trying to rape her. While awaiting execution he claimed to have committed eleven murders, but these claims could not be verified. |
| Bevan Spencer von Einem | Australia | 1979–1983 | 1 | 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 several weeks before their bodies were abandoned in the countryside near Adelaide. Police believed that von Einem had several accomplices, none of whom was 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 four 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. |
| Paul Bateson | United States | 1975–1977 | 1 | 10 | Bateson, known for his involvement in The Exorcist, stabbed film journalist Addison Verrill to death after having sex with him in 1977. While imprisoned for the murder he allegedly bragged about committing the "bag murders", a series of murders of six gay men in New York City who were dismembered and dumped in the Hudson River, and supposedly admitted three other murders to an acquaintance prior to Verrill's murder. However he was never charged with any crimes apart from Verrill's murder due to lack of evidence. |
| Derek Percy | Australia | 1965–1969 | 1 | 9 | Percy abducted and murdered 12-year-old Yvonne Tuohy in 1969 and was remanded indefinitely after being found mentally unfit for trial. A wider investigation found that his movements around the country and physical description linked him to multiple unsolved murders and disappearances of children, including the Wanda Beach Murders in 1965, the Beaumont children disappearance and the murder of Allen Redston in 1966 and two other unsolved cases in 1968; Percy himself claimed to be unable to remember if he had killed anybody else. |
| Brian Field | United Kingdom | 1968–1996 | 1 | 5 | Field raped and murdered 13-year-old Roy Tutill in 1968, but was not convicted until 2001, in the interim serving time in prison for sex offences against children. He is the prime suspect in the disappearance of Patrick Warren and David Spencer in 1996, and a person of interest in the 1985 disappearance of Lee Boxell and the murder of another child, Mark Billington, in 1984. |
| Lowell Amos | United States | 1979?–1994 | 1 | 4 | Detroit businessman sentenced to life imprisonment in 1996 for the murder of his third wife. Suspected of, but never charged with the deaths of two previous wives and his mother, all of whom died under suspicious circumstances and left life insurance policies to Amos that, at least in one case, Amos himself had bought against the will of the insured. |
| Robert Durst | United States | 1971–2001 | 1 | 3–6 | Durst was a suspect in the 1982 disappearance of his wife Kathleen McCormack, who vanished after arguing with Durst. He murdered his longtime friend Susan Berman, who had provided him with an alibi for the disappearance, in 2000, and in 2001 killed and dismembered a neighbour named Morris Black but was acquitted on grounds of self-defense. He was convicted of murdering Susan Berman in 2021 and was also charged with the murder of Kathleen McCormack, but died before he could stand trial for that crime. Durst was also investigated as a suspect in the 1971 disappearance of Lynne Schulze and the disappearances of Karen Mitchell and Kristen Modafferi in 1997. |
| Charles Albright | United States | 1990–1991 | 1 | 3 | Albright was convicted of the 1991 murder of prostitute Shirley Williams, who was shot twice in the head and had her eyeballs removed by the killer. He was accused of two similar murders of sex workers but was not convicted. |
| John Cannan | United Kingdom | 1986–1987 | 1 | 3 | Cannan, a serial rapist, is serving a life sentence for the 1987 kidnap, rape and murder of Shirley Banks. Police have also named Cannan as the prime suspect in the disappearance of Suzy Lamplugh and the murder of Sandra Court, both of which took place in 1986. |
| Bennett Clark Hyde | United States | 1909 | 1 | 3 | Hyde was accused of murdering Thomas H. Swope and two members of his family under the guise of treating them for a typhoid epidemic in order that his wife would inherit a sizable amount of money. He was convicted of the murder of Thomas Swope, but his conviction was overturned on a technicality, two further trials ended in a mistrial and a fourth trial was not proceeded with. |
| David Moor | United Kingdom | 1970s–1999 | 0 | 300 | British doctor who was prosecuted for the "euthanasia" of a patient. He was found not guilty, but then admitted in a press interview to having "helped" 300 people to die. Some press reports referred to him as "Britain's greatest serial killer" and "Doctor Death". If the 300 victims are accepted as murder victims, he would have killed more than the most prolific serial killer known to the world, fellow British doctor Harold Shipman. |
| Edgar Matobato | Philippines | 1988–2013 | 0 | Hundreds | Self-confessed hitman and serial killer claiming to have killed people as part of the Davao Death Squad; his claims' authenticity has been challenged. |
| John Bodkin Adams | United Kingdom | 1946–1956 | 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 sabotaged for political reasons.[failed verification] |
| The Man from the Train | United States | 1898–1912 | 0 | 40–100+ | Murdered entire families in their sleep, arriving and departing by train. Existence (and probable but not proven identity) discovered more than 100 years after the murders, by analysis of contemporary records, showing a markedly common modus operandi for many previously unconnected murders. |
| Ivomoku Bakusuba | Ruanda-Urundi | 1940s | 0 | 67 | Confessed to killing 67 children by strangling them with a bedsheet. Killed himself, "probably in late 1940s or in early 1950s". As information on this serial killer was only revealed by a police officer in 2018 during a conversation with a Brazilian writer, and there is no information on his conviction, the confirmation that he was a serial killer is debatable. |
| Manchester Pusher | United Kingdom | Since 2007 | 0 | 61+ | Alleged serial killer supposedly responsible for the deaths of dozens of people drowned in canals in Manchester. Proponents of the theory point to the "alarming" number of deaths occurring in the Rochdale, Ashton and Bridgewater Canals since the early 2000s, with many of the victims being young gay men (as Manchester's canals have historically been used as gay cruising areas), but police have dismissed the serial killer theory and maintain that the deaths are unrelated. |
| David Parker Ray | United States | 1950–1999 | 0 | 60 | Torture-murderer possibly aided by numerous accomplices, including his girlfriend. Targeted victims around Truth or Consequences, New Mexico. Convicted of attempted killing of three victims and is suspected of 60 murders, even though no bodies were ever found. Known as the "Toybox Killer" for the self-built mobile home he used in the rape, torture, and killing of women. |
| Smiley Face Killer | United States | 1990s–2000s | 0 | 40+ | Theoretical serial killer(s) thought by some sources to have drowned college-aged young men across the northern part of the country since 1997; most experts suggest that the deaths were accidental. |
| Howard Martin | United Kingdom | 1977–2010 | 0 | 18+ | British doctor who was prosecuted in 2005 for the deaths of three patients but was acquitted. However, the General Medical Council then struck him off as a doctor in 2010 for "hastening" the death of 18 people. He admitted to a newspaper to have killed two of these individuals. |
