was the last survivor of the North Side gunmen; his succession had come about because his similarly aggressive predecessors Vincent Drucci and Hymie Weiss had been killed in the violence that followed the murder of original leader Dean O'Banion. Capone was convicted on three counts of income tax evasion on October 17, 1931 and was sentenced a week later to 11 years in federal prison, fined $50,000 plus $7,692 for court costs, and was held liable for $215,000 plus interest due on his back taxes. Capone later died of heart failure as a result of apoplexy on January 25, 1947. From Nitti to Accardo 1930s–1950s In 1931, Nitti was also convicted of tax evasion and sent to prison; however, Nitti received an 18-month sentence. When Nitti was released on March 25, 1932, he took his place as the new boss of the Capone Gang. Some revisionist historians claim that Nitti was a mere "front boss" while Paul "The Waiter" Ricca was the actual boss of the Chicago Outfit. Over the next decade, The Outfit moved into labor racketeering, gambling, and loan sharking. Geographically, this was the period when Outfit muscle extended to Milwaukee and Madison, Wisconsin, Kansas City, and especially to Hollywood and other California cities, where The Outfit's extortion of labor unions gave it leverage over the motion picture industry. In the early 1940s, a handful of top Outfit leaders went to prison because they were found to be extorting Hollywood by controlling the unions that compose Hollywood's movie industry, and manipulating and misusing the Teamsters Central States Pension fund. In 1943, the Outfit was caught red-handed shaking down the Hollywood movie industry. Ricca wanted Nitti to take the fall. However, Nitti had found that he was claustrophobic, years earlier while in jail for 18 months (for tax evasion), and he decided to end his life rather than face more imprisonment for extorting Hollywood. Ricca then became the boss in name as well as in fact, with enforcement chief Tony Accardo as underboss—the start of a partnership that lasted for almost 30 years. Around this time, the Outfit began bringing in members of the Forty-Two Gang, a notoriously violent youth gang. Among them were Sam "Momo" Giancana, Sam "Mad Sam" DeStefano, Felix "Milwaukee Phil" Alderisio, and Fiore "Fifi" Buccieri. Ricca was sent to prison later in 1943 for his part in The Outfit plot to control Hollywood. He was
