The President's Commission on the Assassination of President Kennedy, known unofficially as the Warren Commission, was established to investigate the assassination of President John F. Kennedy. Its 889-page final report was presented to President Johnson on September 24, 1964 and made public three days later. It concluded that Lee Harvey Oswald acted alone in killing Kennedy and wounding Texas Governor John Connally and that Jack Ruby also acted alone when he killed Oswald a few days later.
Closest witness to the assassination, Jean Hill. She thought she heard more than 3 shots, then ran up the grassy knoll to give chase but she was arrested by a patrolman. She claimed she was questioned to the point of intimidation and was amazed at the Warren Commission's falsified report of her testimony.
