With increasing violence and government presence in Italy, Sicilians and Neapolitans alike found positions in the growing drug trafficking market of New York City's Five Families in the early 20th century. The Pizza Connection, a heroin-trafficking operation involving Salvatore Catalano, a capo of the Bonanno crime family, and Gaetano Badalamenti, a Sicilian mafioso, was largely organized by Zips. The Zips were effective because they were unknown in the United States and had no police records. They generally congregated in the Knickerbocker Avenue area.
