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.

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.

She surrendered to police later that day. After her first trial ended in a hung jury, Broderick was convicted of two counts of second-degree murder at a second trial in 1991 and sentenced to 32 years to life imprisonment.

Bradley Murdoch became one of Australia’s most infamous killers after murdering British backpacker Peter Falconio in the Northern Territory Outback in 2001.

Murdoch was portrayed as a violent drug-running truck driver with links to criminal networks across remote Australia. His conviction became one of the country’s most high-profile murder cases, inspiring documentaries, books and films while generating decades of speculation about what truly happened in the Outback. Murdoch maintained his innocence until his death from throat cancer in 2025, never revealing the location of Falconio’s remains.
