What happened to JFK's assassin?

J. F. Kennedy, the 35th president of the United States, was assassinated in Dallas, Texas, on November 22, 1963. His accused killer was Lee Harvey Oswald, a former U. S. Marine who had embraced Marxism and defected for a time to the Soviet Union. Oswald never stood trial for murder, because, while being transferred after having been taken into custody, he was shot and killed by Jack Ruby, a distraught Dallas nightclub owner.
