SAM GIANCANA FBI FILES
4,235 pages of FBI, CIA and Congressional files covering Sam Giancana. Much of the material was not declassified until November 2017.
Reputed syndicate boss in Chicago from 1957 to 1966, Giancana is believed to have worked for Al Capone in the 1920's. He was arrested approximately 70 times and twice sentenced to prison, for burglary, five years, and operating an illegal still, four years. Sam Giancana rose within the Chicago organized crime syndicate until he became syndicate leader in 1957. In 1965 he was sent to jail for contempt of a federal grand jury. After release he left the country. In 1974, after an eight-year stint in Mexico, Giancana was deported back to Chicago
The U.S. Senate Intelligence Committee scheduled Giancana to testify about his alleged involvement in a CIA plot to assassinate Fidel Castro. Giancana was murdered shortly before he was scheduled to testify before the Church Committee. Giancana died from gunshot wounds, one bullet in the back of his head, five into his mouth, received at his Oak Park, Illinois home.
The files cover his various criminal activities and criminal associates. Special attention is given to Giancana's involvement in the CIA plots to assassinate Fidel Castro. THE JFK Assassination Records Review Board was interested in reviewing his files because Giancana expressed hostility toward the Kennedys because of the Kennedys’ war against organized crime. Giancana came under the radar of the Agencies because he had associates in common with President Kennedy, notably Frank Sinatra and Judith Campbell Exner; Giancana allegedly contributed to Kennedy’s 1960 presidential campaign; and was rumored to be linked to an alleged Joseph P. Kennedy illicit liquor trade.
