At the end of season 2, when Dugan is shot, he is shot while facing the two men in the masks who were shooting him, which would mean he was shot in the chest or front of his body. However, in this episode (the episode when Dugan is found), the Chief finds his body in the woods laying on his stomach, with blood stains on his back, making it look as if he had been shot in the back and bled through his shirt.
