In Six Seconds in Dallas, Thompson argued that the available physical evidence, corroborating eye-witness accounts, showed that multiple shots were fired at President Kennedy in Dallas on November 22, 1963, strongly implying the existence of an assassination conspiracy. Based on an examination of the Zapruder film, Thompson's book contends that three individuals fired four shots at Kennedy in Dealey Plaza: the first shot was fired from the Texas School Book Depository and struck Kennedy in the back; the second shot was fired from the Dallas County Records building and struck Governor John Connally; the third and fourth shots were fired from the Texas School Book Depository and the "grassy knoll" and almost simultaneously struck Kennedy in the head.
