When the original head of the Morello Family, Giuseppe Morello emerged back on the scene after a decade behind bars, he immediately took back the reigns from his younger half-brother, Vincenzo Terranova. Morello quickly formed an alliance with one of his former Capo"s, the now emerging new Mafia boss of Lower Manhattan"s Little Italy, Joe Masseria.
