John Fitzgerald Kennedy, the 35th President of the United States, was assassinated at 12:30 p.m. Central Standard Time (18:30 UTC) on Friday, November 22, 1963, in Dealey Plaza, Dallas, Texas. Kennedy was fatally shot by Lee Harvey Oswald while traveling with his wife Jacqueline, Texas Governor John Connally, and Connally's wife Nellie, in a presidential motorcade. A ten-month investigation from November 1963 to September 1964 by the Warren Commission concluded that Oswald acted alone in shooting Kennedy, and that Jack Ruby also acted alone when he killed Oswald before he could stand trial. Kennedy's death marked the fourth and latest successful assassination of an American President. Vice President Lyndon B. Johnson became President upon Kennedy's death, taking the constitutionally prescribed oath of office onboard Air Force One at Dallas' Love Field airport before departing for Washington, D.C.
