From link below:
The assassination of John F. Kennedy on November 22, 1963 has spurred numerous conspiracy theories, which include accusations of involvement of the CIA, the Mafia, sitting Vice President Lyndon B. Johnson, Cuban Prime Minister Fidel Castro, the KGB, or even some combination thereof. Some conspiracy theories further claim that the United States federal government covered up crucial information in the aftermath of the assassination.[1] Former Los Angeles District Attorney Vincent Bugliosi estimated that a total of 42 groups, 82 assassins, and 214 people had been accused at one time or another in various conspiracy scenarios.
