Deceased Killers

Adolf Eichmann became one of the most infamous figures of the Holocaust as a senior SS officer responsible for coordinating the deportation of millions of Jews and other persecuted groups to Nazi ghettos and extermination camps during the Second World War. Following Germany's defeat, Eichmann fled Europe and lived under a false identity in Argentina before being captured by Israeli intelligence in 1960. He was convicted of crimes against humanity, war crimes, and crimes against the Jewish people before being executed in 1962.

Adolfo de Jesús Constanzo became one of Mexico's most notorious serial killers after leading a violent criminal cult that combined ritualistic beliefs with narcotics trafficking during the 1980s. Operating primarily in Mexico City and Matamoros, Constanzo and his followers carried out numerous murders as part of ceremonies they believed would provide supernatural protection and success. The discovery of multiple victims at his ranch in 1989 exposed one of the most disturbing criminal conspiracies in Mexican history.

Aileen Wuornos was an American serial killer who murdered multiple men in Florida between 1989 and 1990. Operating primarily along highways, she targeted men she encountered while working as a sex worker. Her case gained widespread attention due to her background, her claims of self-defense, and the rarity of a female serial killer receiving the death penalty. Wuornos was convicted of multiple murders and executed in 2002.

Alphonse Gabriel "Al" Capone became one of the most notorious organized crime figures in American history after dominating Chicago's underworld during the Prohibition era. As the leader of the Chicago Outfit, Capone oversaw bootlegging, gambling, prostitution, extortion, and numerous violent crimes throughout the 1920s. Although strongly linked to many murders, including the infamous Saint Valentine's Day Massacre, Capone was ultimately convicted of tax evasion rather than homicide. His criminal empire and public notoriety made him one of the most recognizable gangsters of the twentieth century.

Albert Henry DeSalvo is best known for confessing to the infamous Boston Strangler murders, in which 13 women were killed in the Boston, Massachusetts, area between 1962 and 1964. Although he was never tried for those murders, modern DNA testing later linked him to the final victim, strengthening the case against him. DeSalvo was imprisoned for unrelated crimes and was murdered in prison in 1973.

Albert Fish became one of the most horrifying killers in American history after murdering children during the early 1900s and later sending grotesque letters to victims’ families. Known for extreme sadism, self-harm and cannibalistic behavior, Fish terrorized New York and surrounding states while hiding behind the appearance of a quiet elderly man. Often referred to as “The Gray Man,” “The Boogeyman” and “The Werewolf of Wysteria,” Fish shocked investigators and the public because of the disturbing nature of his crimes and psychological abnormalities. His case became one of the earliest high-profile examples of criminal profiling and remains one of the darkest child murder cases in American true crime history.

Allan Joseph Legere, known as the "Monster of the Miramichi," was a Canadian serial killer, rapist and arsonist who murdered five people in New Brunswick between 1986 and 1989. Already serving a life sentence for the 1986 murder of shopkeeper John Glendenning, Legere escaped from a hospital in May 1989 and spent seven months terrorising the Miramichi region, murdering Annie Flam, sisters Donna and Linda Daughney, and Catholic priest James Smith. He was captured in November 1989 following a massive manhunt and convicted of the four murders in 1991, with DNA evidence playing a major role in the prosecution. Legere remained imprisoned for the rest of his life and died at Edmonton Institution in March 2026.

Allen Lee "Tiny" Davis was convicted of murdering Nancy Weiler and her two young daughters, Kristina and Katherine, during a violent attack at their Jacksonville, Florida, home on May 11, 1982. Davis entered the house armed with a handgun and a length of rope, brutally beat Nancy and shot both children before fleeing with property taken from the home. He was already on parole for previous robbery convictions when the murders occurred. Convicted of three counts of first-degree murder in 1983 and sentenced to death, Davis exhausted numerous appeals before being executed by electrocution at Florida State Prison on July 8, 1999.
