Sam Giancana's home is on South Wenonah Avenue in Oak Park, Illinois. The Chicago crime boss had alienated himself from the Chicago Outfit by attracting too much attention from the public and the federal authorities. He was called before a grand jury in 1966 then wound up spending a year in prison. In order to avoid any more grand jury probes he moved to Cuernavaca, Mexico after his release. In July, 1974, he was arrested by Mexican authorities and deported to the United States. He was living in this home, in Oak Park, when, on June 19, 1975, an unknown gunman entered Giancana's basement kitchen, whether by invitation or force, and shot him in the back of the head while he was cooking a meal. The gunman then turned his body over, fired six more times, and disappeared.
