The Mob Boss Killed 9 Days Before Exposing the CIA

Sam Giancana was one of the most powerful Mafia bosses in America. On June 19, 1975, he was found murdered in the basement of his Oak Park home. Seven shots from a .22 caliber pistol ended the life of the man who once controlled the Chicago Outfit. But this wasn't just another mob hit. Only nine days earlier, Giancana had been subpoenaed to testify before the U.S. Senate's Church Committee about secret CIA assassination plots targeting Fidel Castro. He knew the names. He knew the operations. He knew the relationship between organized crime and American intelligence agencies. Then he was killed. In this documentary, we examine the evidence, declassified records, FBI files, Senate testimony, and decades of investigative reporting surrounding one of the most mysterious murders in American criminal history. Was it the Chicago Outfit? Was it the CIA? Did the FBI look the other way?
