Reputed mob boss is called FBI informant

The Boston Globe reports:

Mark Rossetti, a reputed Mafia leader who was indicted last year on state charges of running a sprawling criminal enterprise of drug trafficking, gambling, and loan sharking, had been working all along as an informant for the FBI, according to documents filed yesterday in Suffolk Superior Court.

No word yet on this one from Chicago Mob boss John "No Nose" DiFronzo.
