This doesn't make any sense. Obviously this person was a trained killer. I think the whole rifle in the woods thing is a prop. It's kind of like the passport they found untouched after nine eleven. I believe it's a distraction to make us think along the line they wanted, or to make us look in the wrong place. A kind of smoke and mirrors or a slight of hand.
It's almost like somebody's making war against us, by deception.
PSYOPS can go both ways. For evil or good.
Not saying anything else.
