Sam Giancana – 1908-1975

Giancana was Chicago’s top syndicate boss from 1957 to 1966, and was reputedly tapped by John F. Kennedy’s father, Joseph P. Kennedy, to exert his influence among labor unions to swing the 1960 election in favor of JFK. In 1975, Giancana was gunned down in his Oak Park (Illinois) home by unknown assailants shortly before he was scheduled to appear before the U.S. Senate Intelligence Committee to testify concerning his alleged involvement in a CIA plot to assassinate Cuba’s Fidel Castro in the early 1960s.
