All he had was an Italian sir name and kicked up so he could conduct business on his own turf with his own crew...
I don't think it was even an official affiliation like "associate"....
But why did Mark Silverman give him a primary role in his book about the Salemme vs Carrozza and Russo war? Was DeCologero a major player in that conflict or is Silverman just overblowing his importance for some reason?
