John F Kennedy, the 35th president of the United States, was shot dead in his open-top limousine as the presidential motorcade passed through Dallas, Texas, on 22 November 1963. The horror that unfolded that winter day at the height of the Cold War, just before Thanksgiving, proved to be one of the defining events of the 20th century.
According to the official narrative, as established by the Warren Commission, former US Marine Lee Harvey Oswald fired the fatal shot from the upper floors of the Texas School Book Depository before being arrested and then murdered himself by local businessman Jack Ruby two days later, with both men ruled to have been acting alone.
