Thanks former FBI agent William Roemer claimed it was Bonanno who betrayed Luciano.
While Luciano believed that Vito Genovese had tipped off the US government to his whereabouts in Cuba, he did not live to find out that it was "Joe Bananas" Bonanno who tipped off the New York City newspapers to Luciano's whereabouts in Cuba in February 1947. Joseph Bonanno was highly respected and feared, but he was also ruthless and highly ambitious. Roemer wasn't the most reliable unfortunately. Its pretty sad, the more i research, the more i see how little these authors fact check their claims
