Reputed Mob Boss Allegedly An Informant

Authorities allege he's a top figure in Boston organized crime. He's also an informant. And his name is not James "Whitey" Bulger.

The Boston Globe reports court documents filed Thursday in Suffolk Superior Court indicate reputed Mafia leader Mark Rossetti had been working as an informant for the FBI.

The documents were filed by two lower-level players in Rossetti's alleged crime ring and do not identify Rossetti by name. But he can be clearly identified through descriptions of his conversations with his FBI handler and through a state police organizational chart of his alleged crime ring.

An FBI spokesman declined comment.

Rossetti's lawyer argued that there is no public proof that her client worked as an informant.

Rossette was indicted last year on state drug trafficking, gambling and loan sharking charges.
