Im surprised they dont mention finding the "wounded bear". That would be key in confirming the story. If there is no wounded bear, or no blood from a wounded bear, it would really make you think this "accident" was planned.
I dont know, maybe Im just being an untrusting Jersey boy, but something seems fishy to me! I would hope thats not the end of their investigation. Im sure the LEO's up there have more time on their hands than most states LEO's, shouldnt be any excuse to not pursue this.
