Johnny dio definetly one of the biggest labor racketeer in the history of ny. His brothers were in his crew as well as his uncle james plumeri aka jimmy Doyle. Dio was ruthless to say the least. There is a ton of info on him, one thing that I never could figure out was that Doyle was strangled to death in the early 70s. Def a mob hit and dio was in the can where he died later in the decade. My ? Is who hit Doyle and was dio in on the hit or also on the hit list. Hopefully someone can give some info
