Can You Find the Killer?

This is for the contest. Go support ~Wolf-Den, it's a cool, but highly unnoticed, and because of that, unactive club. It looks poorly done, but I wanted to make something for the club...

Anywho, every year the gray wolf population is diminishing. They are endangered, and yet they are still being hunted. The law has yet to pass to stop hunting of gray wolves up in Alaska and such. They are considered dangerous, and a threat to humans. It's actually a fact that no human has ever been attacked by a healthy wolf. And if a wolf goes after someones flock of sheep or something, they're just trying to survive, like everything else. So, can you find the real killer in this picture?
