I worked a shooting years ago, where a drunk shot two brothers in front of a night club. Both were on the ground when I got there. The first had an entry wound in the chest, about three inches below and to the center. Lung shot. The second ran about sixty feet and was hit from behind in the right elbow.
First guy had zero blood visible, but vomited profusely. Lots of blood on number two and you would have thought he was dying. All this from two shots with a .22lr revolver. Both survived with number one having an extended hospital stay.
I got my shooter at his home.
