Retired agent William “Bill” Grace served more than 33 years with the FBI. In this episode of FBI Retired Case File Review, he reviews the “Wolf Ticket” investigation where 13 Philadelphia Roofers Union Local 30 officials were convicted of racketeering, extortion, and bribery. The case uncovered numerous ties between union leaders, organized crime, and public officials. The key to the successful investigation was the surreptitious recording devices installed in the union hall that secretly taped conversations between union leaders and others. Prior to his transfer to the Philadelphia Division, where he worked Labor Racketeering and Corruption cases in Philadelphia and South Jersey, Bill Grace was assigned to the Bureau’s Baltimore and New Haven Offices. He currently continues to work for the FBI as a contract Asset Forfeiture Investigator.
