"A large part of it is to see if there are irregularities with the animal that may explain what led it to become predatory," 

"...had a gunshot wound to the jaw. "

I'm no bear expert but I imagine having been shot in the face may have contributed to the bear becoming predatory. So, with causality factored in, whomever shot the bear in the face (without actually killing it) is indirectly responsible for the mauling. If only there existed, I don't know? Some type of spray? Instead of whatever wimpy caliber that was used to "maim" and aggravate the bear, which only resulted in the bear attacking and killing someone.
