In 1926 Giancana was arrested for murder. However, charges were dropped after the key witness was murdered. He was later sent to prison for theft and burglary. On his release he went to work for leading gangster Paul Ricca. By the 1950s Giancana was one of the leading crime bosses in Chicago.
In 1960 Giancana was involved in talks with Allen W. Dulles, the director of the Central Intelligence Agency (CIA), about the possibility of murdering Fidel Castro.
