“The Texan didn’t walk up to the unconscious man and pump another couple rounds into the crook.”
Whether the robber was unconscious or not is a major point of dispute in the case. My understanding is the video tape does not show the robber on the floor when the robber is shot the second time.
If we’re talking about Oklahoma, the first shot was to the crook’s head.
He was definitely down.
The pharmacist went to get a second gun and go after the other crook.
When he returns, that’s when he shoots the first guy a couple more times.
