While unfortunate, let's remember that something benefitted on the forestfloor. Be they predators, scavengers or microfauna, right up to the end it was all consumed. We are assuming slob hunters, but we may be a little too hard on hunters.
Not everyone out there is a seasoned hunter, many people get buck fever, be it does or bucks.

Additionally, are there any diseases or over crowding of deer in your area? Without knowing the actual cause of death, its not fair to assume someone is responsible. Is there a road crossing in the area? Maybe they were wounded by auto encounters and crawled off and died. And maybe there are some slobs in your neck of the woods, that need some educating, or a helping hand in learning the finer points of shot placement, choosing the right deer, quality management etc.
