On the eve of his planned departure from western Pennsylvania, he was shot to death within his parked automobile. Three associates were in the automobile with him at the time. They claimed to be innocent of the killing. All three said a small, slight-built man jumped up on the car's runningboard, fired the fatal shots and escaped so quickly that they could not act to prevent or to capture him. Police didn't believe the story. They figured it would have taken a giant to reach far enough into the car to fire the shots through the back of Conti's driver's seat, and that giant would have been virtually in the lap of a passenger as he fired. Further, the murder weapon was recovered and turned out to be a pistol that required time-consuming manual cocking between shots.
