It is now reported on the news that the hunter was indeed, killed by the bear. To start with, they didn't know for sure, if the bear killed the hunter, or just "mauled' him, after the hunter may have died from other causes. However, they state autopsy reports show the bear killed the man.
Apparently no evidence of whether it was a grizzly, or a black bear. I wonder if there would be DNA evidence of the bear on the victim to determine if it was grizzly, or black? Or did they even think of this at autopsy? Lots of "What if," tales will likely be told on this one. How did a bear manage to kill a hunter armed with modern bow hunting equipment?
If they could find a bear with an arrow in it, much more could be learned, or guessed at.
Was the hunter too law abbiding and let a legally protected grizzly get too close?
