Who can hear the words grassy knoll or Texas School Book Depository without a shudder of horror? Who can forget that one minute the handsome, smiling president was waving to the crowds, and the next minute his wife was bravely trying to hold his shattered head together? The story of what happened on that day is very poignant for Antoinette Giancana. Her father, Sam Giancana, ordered the assassination of President John Fitzgerald Kennedy. JFK and Sam is a tale of two murders. The first occurred in Dallas on November 22, 1963, the second in Oak Park, Illinois, on the evening of June 19, 1975. The first was ordered by Sam Giancana to avenge his betrayal by the Kennedys. The second assassination was carried out to prevent Giancana from testifying before the Church Committee about his role in the many plots of the CIA to assassinate Fidel Castro. Ironically, both men--John Kennedy and Sam Giancana--were killed because of their relation ship to each other and the events that grew out of that association. In short, if the two families had never worked together, JFK would not have been assassinated in 1963--but he also would likely never have been president. JFK and Sam is unique among the many books about the Kennedy assassination. Written by someone with access to the key figures in the tragedy, it names the murderers and traces their movements on November, 22, 1963. It also discloses the identity of the shooter from the grassy knoll near the Texas School Book Depository, his taped confession, and his face-to-face meeting with Antoinette in the Joliet state prison where he is serving a life sentence for killing a policeman. Coauthors John R. Hughes and Thomas H. Jobe--experts in neurophysiology, neurology, and neuropsychiatry--also provide expert analysis that shows what could not have happened and what did happen in Dallas on November 22, 1963. Basing their analysis on the nature of President Kennedy's injuries and his body's reaction to the bullets, Hughes and Jobe provide. medical basis that supports the story told by the man who assassinated the president of the United States.
