Big Billy was close to the Youngstown, OH faction of the Pittsburgh Family. Russell Buffalino and Gabriel Mannarino were "exceptionally close" friends and D'Elia's friendship with Pittsburgh through Henry Zottola and Mike Genovese led him to an opportunity for garbage hauling with Joey Naples and Lenny Strollo of Youngstown. Also, a guy by the name of Vic Calautti, Youngstown businessman and owner of National Builders Corp handled all the money laundering through Swiss banks as well as other countries for guys like Angelo Bruno, John Stanfa, Billy D"Elia, Russell Bufalino, Mike Genovese etc. Check out these articles:
