On this day, three top New York Mafia bosses were sentenced to 100 years in prison each in a major blow to the city’s “Five Families.”

The bosses of the Colombo, Genovese and Lucchese organized crime families received the century-long terms for membership on a commission that had settled disputes, divided loot and occasionally ordered killings for the Mafia since Prohibition.

 Time magazine called this “Case of Cases,” possibly “the most significant assault on the infrastructure of organized crime since the high command of the Chicago Mafia was swept away in 1943.”
