James "Jimmy" Petrille was a friend of Johnny Sack's who became his consigliere once Johnny took over as boss of the family. However, it is revealed in "All Due Respect" that Petrille had been a turncoat cooperating with the FBI and gave up information going back to Sacrimoni's criminal activities in 1981, which was instrumental in Johnny's arrest. It is unknown what damaging evidence Petrille gave about either the DiMeo crime family or his own Lupertazzi crime family. His fate is unknown, although it is implied that he disappeared into the Federal Witness Protection Program.
