Didn't happen to me, but a friend told me about an article he read......man was elk hunting and shot a nice elk, when after some time a man dressed in complete black comes up to the hunter and says he's with fish and game and that he took the elk illegally and must forfit the elk. Hunter being suspicious and knowing he took it legally, told the guy to get lost etc......guy knocks him over the head/unconscious, hunter comes to the elk head is gone!
