A guy that my family knows was hunting some public land. I heard a shot from private land and looked to see a nice 8 point running his way. He shot and dropped it. When he went over to the deer he noticed that they did hit the deer but really high in the back end and it wasnt going to die. He proceeded to gut and tag the deer, then put the deer on his deer carrier and started taking it out of the woods. Then 4 guys who has originally shot the deer walked up, ripped the tag off the deer and stole the deer. I only know what happened up to this point. The game warden was contacted. What would you do in this situation?
