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 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.

Allen Lee Davis was an American man convicted of the 1982 murders of a pregnant woman and her two young daughters in Florida. The crime was noted for its extreme brutality and shocked the local community. Davis was sentenced to death and executed in 1999. His execution became controversial due to visible injuries sustained during the process, sparking debate over the use of the electric chair in capital punishment.

Andrei Chikatilo became one of the Soviet Union’s most infamous serial killers after murdering and mutilating dozens of women and children across Russia and Ukraine between 1978 and 1990. Nicknamed “The Butcher of Rostov” and “The Red Ripper,” Chikatilo terrorized the Soviet Union for over a decade while authorities struggled to identify the perpetrator amid political pressure, investigative failures and widespread public fear. His crimes shocked investigators because of their extreme brutality, sexual sadism and mutilation of victims. Chikatilo appeared outwardly quiet and socially awkward, allowing him to blend into ordinary Soviet society while secretly carrying out one of the deadliest serial murder sprees in modern history. His eventual arrest and confession exposed major flaws within the Soviet criminal justice system and transformed the case into one of the most notorious serial killer investigations ever conducted behind the Iron Curtain.

Andrew Cunanan was an American spree killer responsible for a series of murders across multiple U.S. states in 1997. His crimes unfolded over several months and involved both known associates and opportunistic victims, culminating in the high-profile murder of fashion designer Gianni Versace. Cunanan became one of the most wanted fugitives in the United States during the manhunt that followed. His killing spree ended when he died by suicide in July 1997 before he could be captured and tried.
