If several of your hunting group use the same trail to get to their spots it shouldn't be too hard to see where he dragged the doe out or find the spot where he dressed it. Ask yourself some questions and draw your own conculsion from the answers. Was he excited? Did he have a story on his kill? Every inexperianced hunter that I know likes to tell a very colorful story about the deer they tag. Did anyone hear a shot about the time and in the same general area your friend killed his deer?

Oh, a bigger gun doesn't make up for poor shooting skills. Sorry, I just had to get that in.
