So they believe Rizzuto gave the okay. We don't know the exact reason WHY he was killed, though, or why they did in Sicily
He was killed because of Rizzuto. He like Di Maulo, simply rode the fence during the war and once Vito was out he even tried to get Joe Bravo to meet with him in Cuba or the Dominican Republic and he refused to go. That right there signed his own death warrant.
