Al Bruno got killed because he spoke with an FBI agent at a restaurant in Springfield, MA. The FBI agent mentioned something about Emilio Fusco getting made and Bruno told the agent that Fusco shouldn’t have gotten made. Bruno was in jail at the time he was made. That conversation got back to Fusco, who was on trial for something at the time, and it was documented. Fusco got a copy of the paperwork and gave it to Felix. Felix brought it down to NYC to Artie. Pretty sure that’s what got the ball rolling but I also think Bruno was on the outs with NYC at that point.
