I almost had the opposite thing happen to me a few years ago. I was hiking off a mountain and heard a gunshot in the direction of my camp. About three hours later and in the dark, I stumbled onto a dead elk 100 yards from camp. I hiked around for a bit and I couldn't see any lights or hear any noises. The low temp that night was going to be -15, so I imagine that elk would have been pretty frozen by morning. I was walking back to the elk with a knife and with the intention of field dressing it when the folks who shot it rode up on horses. I did not have to decide whether to call the warden, tag it, pack it out, ect. because the shooter showed up, but I had no intention of letting that elk lay there and go to waste. If those dudes did not show up and if I had carried that elk out of the woods, I certainly wouldn't have felt like I stole someone else's elk.
