A friend of mine shot a deer, made a marginal hit. Went home to get his dog that tracks pretty well (he can't see blood very well), came back within 1 hour and after tracking a bit came up to a father and 2 sons tracking his deer. Apparently one of them saw the deer then found some blood. They said they waited a while, assumed nobody was following, and they thought maybe they could track and get another arrow into it. There's all kinds of "hunters" out there.
