Rifle Accident Kill
Did Richard somehow make Sonny shoot his friend? By predicting where he would aim or something
Or was it actually Sonny's accident?
It was a hard shot for a pro and Sonny would not have been near the skill level to make the shot. Richard knew what gun Sonny had because he was in his house and could have easily adjusted the sites on the gun. Whatever the case, Sonny was not going to hit whatever he aimed for. Plus with hald the film left to go, it was obvous he was going to miss Richard.
