Why do you not think it’s true? Not challenging you ... I don’t know enough about it to know if it is true.
There’s a level of detail about the injuries that you can’t get from casual observation, so I’m thinking either he or the reporter is getting creative. Head wounds are pretty messy, and you can’t tell much of anything unless you’re somebody who’s treating the patient. Bullets generally don’t sit on top of the skin where they can be observed, you usually have to probe to figure out where they are. So, it’s the combination of too much detail from someone with too little training that makes me skeptical. One or more with head wounds might be an accurate observation, though.
