On October 17, 1931, notorious Chicago gangster Al Capone was found guilty of federal income tax evasion, bringing an extraordinary criminal career to an unexpectedly ordinary conclusion. Born in Brooklyn, New York, in 1899 to Italian immigrant parents, Alphonse Gabriel Capone became involved in street gangs during his youth and acquired the nickname “Scarface” after a knife attack left permanent scars on his face. He eventually moved to Chicago, where he joined the criminal organization operated by Johnny Torrio. When Torrio retired in 1925, Capone assumed control of an expanding empire built on illegal liquor distribution, gambling, prostitution, and organized violence. Prohibition had created a thriving underground alcohol market, and Capone was more than willing to supply the merchandise, provided nobody objected to his rather unconventional business practices.

Throughout the 1920s, Capone accumulated enormous wealth and influence while Chicago endured bloody confrontations between rival criminal organizations. His operation relied on intimidation, political corruption, and violence to protect its lucrative activities. The infamous St. Valentine's Day Massacre of February 14, 1929, in which seven men associated with a rival gang were murdered, intensified public outrage and brought greater federal attention to organized crime. Although Capone was widely suspected of involvement, he was never convicted in connection with the killings. Federal prohibition agent Eliot Ness and his celebrated team, the Untouchables, targeted Capone's illegal alcohol operations, but investigators working on his finances ultimately secured the conviction that his more violent activities had failed to produce. On October 24, 1931, Capone received an 11-year federal prison sentence, a $50,000 fine, and additional financial penalties. For a man who had spent years outmaneuvering rival gangsters and law enforcement officers, being defeated by the Internal Revenue Service was a particularly expensive lesson in bookkeeping.

Capone initially served his sentence at the federal penitentiary in Atlanta before being transferred to Alcatraz Island in 1934, where his influence and privileges were considerably reduced. His health deteriorated during imprisonment, particularly because of complications from syphilis, and he was released in November 1939 after serving approximately seven and a half years. He spent his remaining years largely withdrawn from public life at his Florida residence on Palm Island, where he died on January 25, 1947. Capone's conviction became a landmark in the federal government's campaign against organized crime, demonstrating that financial investigations could succeed where traditional criminal prosecutions had struggled. The gangster who had survived Chicago's violent underworld was ultimately brought down by something far less glamorous than a rival mob boss: unpaid taxes.
