The girl was shot in the back as evidenced by the mess her chest area was in the crime scene photo. I believe the guy was shot first in the chest, at which point the girl tried to run, and was shot in the back. Both were still breathing or to just make sure they weren't, they were finished off with neck shots. The male naturally would have been disabled first because the killer would have had no fear of the girl. He knew she wasn't going anywhere anyway since he had the gun. Whatcha wanna bet Lonnie Henry was the truck driver that made the discovery?
