Deceased Killers

Herbert William Mullin became one of California's most infamous serial killers after murdering 13 people in and around Santa Cruz between October 1972 and February 1973. Mullin later claimed he believed the killings were necessary to prevent catastrophic earthquakes, a delusion linked to severe mental illness. His short but deadly murder spree ended with his arrest in February 1973, and his case remains one of the most widely studied examples of psychosis and serial homicide in the United States.

Ian Duncan Stewart Brady became one of the United Kingdom's most infamous serial killers after carrying out the Moors Murders with Myra Hindley between 1963 and 1965. The pair murdered five children and concealed several victims on Saddleworth Moor, creating one of the most notorious criminal cases in British history. Regarded as the dominant figure in the partnership, Brady spent the remainder of his life imprisoned and became a symbol of extreme criminality in the United Kingdom.

Israel Keyes became one of America's most infamous serial killers after carrying out a series of meticulously planned murders across multiple states between 2001 and 2012. Unlike many serial offenders, Keyes travelled extensively, buried "kill kits" years in advance, and deliberately selected victims with no personal connection to him. Although he confessed to eight murders, investigators believe the true number of victims may never be known due to his suicide before revealing the full extent of his crimes.

Ivan Milat was an Australian serial killer responsible for the murders of multiple backpackers in New South Wales between 1989 and 1992. His crimes became one of the most notorious cases in Australian criminal history. Milat targeted travellers and used deception to gain their trust before carrying out violent attacks. He was later convicted and sentenced to life imprisonment without parole, remaining incarcerated until his death in 2019.

Justin Jason Keeding, widely known as the “Little Merchant Killer,” became one of the more notorious robbery-murder offenders of the early twentieth century after being linked to violent attacks against rural merchants and storekeepers. Operating during the 1920s, Keeding allegedly targeted isolated business owners in smaller communities, earning his nickname through repeated attacks connected to robbery and financial gain. The case generated significant regional media attention during the era because of the fear surrounding traveling offenders targeting small-town businesses. Authorities portrayed Keeding as a violent drifter willing to kill during robberies, while newspapers sensationalized the crimes through dramatic reporting common during the period. His eventual death in 1926 closed a violent criminal chapter that remained part of regional crime history for years afterward.

James Dupree Henry was convicted of murdering 81-year-old Orlando civil rights leader Zellie Riley during a robbery at Riley's home in March 1974. Henry bound and gagged Riley before suffocating him and stealing property from the residence. Five days later, Henry shot and seriously wounded Orlando police detective Ronald Ferguson while attempting to avoid arrest. Convicted of first-degree murder and sentenced to death, Henry maintained his innocence throughout his decade on death row. His case became the focus of civil rights and capital-punishment campaigns, with Jesse Jackson, Coretta Scott King and Riley's son asking Florida officials for clemency. Henry was executed by electrocution at Florida State Prison on September 20, 1984.

Jared James Dicus murdered his 21-year-old wife, Anggy Diaz, at their home in Waller County, Texas, on January 11, 2023, less than three months after they were married. After killing Diaz with a kitchen knife, Dicus decapitated and partially dismembered her body before confessing to investigators. He later pleaded guilty to murder, was sentenced to 40 years in prison in July 2024, waived his right to appeal and any insanity defense, and remained incarcerated until his death in prison in January 2026 from a self-inflicted injury.

Jeffrey Dahmer is one of the most disturbing figures in American criminal history, often dubbed the “Milwaukee Cannibal.” Between 1978 and 1991, he carried out a series of brutal murders involving necrophilia, cannibalism, and body preservation. His crimes shocked the world not only for their severity, but for how long he evaded capture.
