planted that gym bag and ammunition. >> that was supposed to be some kind of murder bag. >> and placed the gun he had used to kill his wife in brian's hand. there's no way brian brought that gun to brett's house a friend testified. >> did you know whether brian had a gun. >> heck no he did not have a gun. brian was scared of guns. there is no way on this earth that brian had a pistol. none. zero. it did not happen. and there was something else. he suffered a major gunshot wound to his arm but it's unlikely the gun would have stayed in his hand. >> in my medical opinion based on shots to the arm, to the forearm and falling over, i believe that the gun fell out of his hand.
