Massetta is a Cleveland native and the son in law of late Los Angeles family boss Peter Milano. He was active in the area of labor racketeering on behalf of the Milano's in movie circles. Massetta along with fellow Los Angeles family member Nicholas Nardi, brother of John Nardi, worked as an organizer for Teamster Local 848 in El Monte. Masetta's influence was such that he was able to guarantee labor peace in Los Angeles, Chicago and New York during a movie shoot proposed by an FBI agent posing as a filmmaker for a cost of $25,000. Massetta demanded 10% up front with $1,500 going to Louie Gelfuso and another $1,000 for Robert Kessler an FBI informant.
