Previous investigation by FBI agents in the Irontower I case determined that the Torretta faction of the Sicilian Mafia used the Café Giardino in Brooklyn, New York to distribute cocaine in the New York metropolitan area in cooperation with the New York Gambino La Cosa Nostra (LCN) family. With the continued investigative focus of Irontower II, it was determined that Gambino LCN Family Capo Giovanni Gambino directed a large international heroin smuggling ring, assisted by his brother Giuseppe, a Gambino LCN soldier, and other Sicilian Mafia members and associates who worked in the United States, Italy, and the Dominican Republic. The principal subjects of this investigation worked and resided in Philadelphia, New York, and New Jersey.
Subsequent investigation determined that this organization extended further down the East Coast, as participants were located between New York and Virginia. The Irontower II investigation produced an initial indictment and nine superseding indictments in subsequent years for violations of federal drug laws.
Irontower II subjects were tried and convicted in the Southern District of New York. Among those convicted with Giovanni and Giuseppe Gambino were four high ranking members of the Sicilian Mafia. The trial was also significant in that Italian cooperating witnesses Francesco Mannoia and Gaspare Mutolo provided landmark testimony documenting the ongoing nexus between the Sicilian Mafia and the American LCN.
Sicilian Mafia member, Rosario Naimo, who acted as a representative to the American LCN for the Sicilian Mafia, a subject of an INTERPOL Red Notice, remains a fugitive and was last known to be living in South America.
