Another theory regarding Carfano's death lies with his vast gambling empire in South Florida and a belief he was making moves to invest in Cuban casinos at the time of his death. With the emergence of Genovese as the new leader of the Luciano crime family in late 1957, former boss Luciano lost a great deal of underworld influence in New York and America. No longer in control of his crime family, longtime Luciano ally and supporter Meyer Lansky, who had vast gambling interests across America, along with casino interests in Las Vegas and Cuba, was in need of a new sponsor and ally within the former Luciano family. Luciano and Costello had given Lansky underworld protection for decades. Now Lansky sought an alliance with new boss Vito Genovese.
