The deer had been shot in a prior season with a Wasp Hammer broadhead. It entered the brain but did not kill the deer. It also passed through the hinge of the jaw and had grown over with bone and prevented the law from opening all but the smallest amount.
I placed one of my aging jaws next to the skull to show how the jaw hinge should look.
Here you can see the opposite healthy side
The bone had grown over the broadhead and through the vent in the blade and bridged the gap.
The upper left arrow shows how much hinge movement was allowed in the jaw, The opening and closing of the mouth had worn a curved area away
The shot appears to have taken from the ground and not an elevated stand and looks to be nearly perfectly broadside. I can’t understand why someone would aim there unless they were taking a neck shot. I think that would have been a poor choice as well.
