East Harlem Purple Gang The East Harlem Purple Gang was a semi-independent gang of Italian American hit-men and heroin dealers who, according to federal prosecutors, dominated heroin distribution in East Harlem and the Bronx during the late 1970s and early 1980s in New York City. Though mostly independent of the Italian-American Mafia and not an official Italian-American Mafia crew, the gang was originally affiliated with and worked with the Lucchese crime family and later with the Bonanno crime family and Genovese crime family. It developed its "closest ties" with the Genovese family, and its remnants or former members are now part of the Genovese family's 116th Street Crew.
