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.

Where was it when he was walking up the stairwell? Did he have it inside the backpack? Wasn't already there waiting for him? Remember, this is a long gun.
