The presumed assassin of President John F. Kennedy. Oswald allegedly shot Kennedy from a high window of a building in Dallas on November 22, 1963, as Kennedy rode down the street in an open car. Oswald was captured the day of the assassination but was never tried; two days after Kennedy's death, as Oswald was being moved by police, a nightclub owner from Dallas, Jack Ruby, shot and killed him. A government commission led by Chief Justice Earl Warren concluded later that Oswald, though active in communist causes, was not part of a conspiracy to kill Kennedy. Many have questioned the findings of the commission.
