Then he saw club owner Jack Ruby take two sharp steps and shoot Oswald from less than two feet away. "What went through my mind was I needed to save my prisoner, so I tried to pull him behind me. But in one second, you don't have much time to do that," says Leavelle, 83, who retired in 1976. "He was too close to me and I couldn't move him. All I did was turn his body. When I turned his body, instead of the bullet hitting dead center in the stomach, it hit him about 4 inches to the left side of the naval. "If it hadn't hit the seventh rib, it would've come on and hit me, but the rib slowed it down. He just groaned and slumped to the floor." Leavelle rode in the ambulance with Oswald to Parkland Hospital. "A med student was doing CPR and I was holding his wrists, trying to get blood pressure and couldn't get any. I told the doctors in the trauma room I want that bullet out. .... It just popped out in a tray, like a grape seed. "I gave the nurse my pocketknife and I said, 'Scratch your initial in that bullet because you and I will testify that that was the bullet.' I wrapped it in a tissue and put it in the crime lab later for analysis. We both did testify several times on it."
