Ferriola became a boss when Turk Torello died in 1979. Sam Battaglia was boss of MP until he went to prison in 1967. After that, it was essentially a shared territory between Aiuppa, Chuck Nicoletti, and a few other guys like Nick Palermo. Eventually, Aiuppa gained complete dominance over the area.

Snakes, in the 70s and 80s was the Cicero crew stronger or the Melrose Park crew?
