Ive also heard about that but theres another story(dont know if its true) that in 1935 McGurn approached Ricca with the idea of approaching Lucky Luciano to back them in a international drug smuggling ring.McGurn knew about Ricca's good working relationship with Luciano and Lansky.Frank Nitti was the "boss" back than but Ricca was the rising star.But in 1936 McGurn was dead and Luciano went to jail.
