The Young Indiana Jones Chronicles Season 2 Episode 6

Jim Colosimo was murdered on May 11, 1920. He immigrated to Chicago from Italy in 1895 and married Victoria Moresco, an established madame in 1905. Within years, Diamond Jim's businesses had expanded to nearly 200 brothels and had gotten into gambling and racketeering. In 1909, he brought his nephew, John Torrio, in from New York to help with threats from a rival gang (it was at this time that Torrio brought Al Capone to help him as Capone had been his lieutenant in Brooklyn). When Prohibition took hold in Chicago, Torrio pushed for their operation to get into bootlegging, but Colosimo didn't want to. After his murder, Colosimo's gang was controlled first by Torrio then by Capone, eventually becoming the Chicago Outfit.
