In 1960 Johnny Roselli was invited to be part of a CIA-Mafia plot to assassinate Fidel Castro. Trafficante and Giancano were already involved and other mobsters had an invested interest having lost their casinos in the Cuban revolution. However, the plot failed as did the CIA’s Bay of Pigs invasion.
It is speculated that he was then part of a conspiracy involving Giancana, Trafficante, Lansky and New Orleans boss Carlos Marcello, along with elements of the CIA and Texas oilmen, to assassinate John F Kennedy. James Files places Roselli alongside Charlie Nicoletti in Dealy Plaza, as one of the assassins.
The fact that Sam Giancana was murdered just before he was due to testify before the United States Senate Select Committee about the attempted assassination on Fidel Castro should have discouraged Roselli from testifying, but it didn’t. His testimony is still classified, but on August 9, 1976 his remains were found in a 55 gallon steel drum floating in Dumfoundling Bay near Miami.
He left his Florida home to go out for a game of golf and was not seen alive again.
