List of serial killers by number of victims

From Wikipedia, the free encyclopedia

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 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 some, 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.

Serial killers with the highest known victim count

The list below is a compilation of modern serial killers who currently have the highest verifiable murder count. It excludes medical professionals and pseudo-medical professionals with their ability to kill simply and in plain sight, and serial killer groups and couples. Murderers falling into these two categories are listed separately further down.

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.

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.

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.

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.^[587]

Alfred Leonard Cline	United States	1930–1945	0	9	Suspected of poisoning his eight wives and one man with sedative-laced buttermilk. Not enough evidence could be found to prosecute him for murder, but he was convicted of forging his victims' wills and died in prison in 1948.
