The Warren Commission report on the assassination of President John F. Kennedy is released after a 10-month investigation, concluding that there was no conspiracy in the assassination, either domestic or international, and that Lee Harvey Oswald, the alleged assassin, acted alone. The presidential commission, headed by Supreme Court Chief Justice Earl Warren, also found that Jack Ruby, the nightclub owner who murdered Oswald on live national television, had no prior contact with Oswald. According to the report, the bullets that killed President Kennedy and injured Texas Governor John Connally were fired by Oswald in three shots from a rifle pointed out of a sixth floor window in the Texas School Book Depository. Oswald's life, including his visit to the Soviet Union, was described in detail, but the report made no attempt to analyze his motives.
