Vincenzo Armeni's ex-wife and Callocchia's wife are sisters. Armeni was close to Agostino Cun-trera.
Callocchia may have been a dissident, but we don't know which group targeted him. The Armenis appeared to have cordial relations with the Rizzutos.
Good point, last year Giuseppe Armeni had for example his funeral service in the Rizzuto-owned Complexe Loreto.
