The Kennedy family has been dogged by tragedy for many generations. On Nov. 22, 1963, a sniper shot and killed John F. Kennedy as he was traveling with a motorcade in Dealey Plaza in Dallas, Texas. The Warren Commission concluded that Lee Harvey Oswald, a former Marine who had defected to the Soviet Union but returned to the United States, acted alone and fired the shots from the sixth floor of a nearby book depository. Many believe the official story is wrong, and 50 years later, conspiracy theories continue to circulate. [Why JFK Conspiracy Theories Won't Die]
Five years later, on June 5, 1968, JFK's younger brother Robert F. Kennedy was assassinated while campaigning for the presidency. He had just won the California presidential primary and was leaving the ballroom of the Ambassador Hotel in Los Angeles, when Sirhan Sirhan, a Palestinian Christian, opened fire and killed the presidential hopeful because of his support for Israel.
