Lee Harvey Oswald, former U.S Marine and Soviet Union defector, is believed to be the sole person responsible for the assassination of President John F. Kennedy. Oswald is believed to have shot three times at the president from a building near the parade route J.F.K took on Nov. 22, 1963.
While several investigation commissions concluded Oswald's guilt soon after the assassination, much speculation existed among the American population. The U.S. House Select Committee on Assassinations had the opposing opinion that Oswald was not in fact alone and that it was two men, not one, who fired at the president. Many conspiracies surround the events of the day, but most state that Oswald was involved in some form.
