just a thought, playing devils advocate here:

all mod saw was a deer on his property that had been shot and killed. mod didnt actually see the guy shoot the deer in his vehicle from the road with a .22, I have to admit that having the .22 on him is going to hurt his defense, unless he had another "legal" hunting rifle in his posession. and as far as him trespassing, it is possible that he shot the deer at another location and the deer ran onto mod's property and died. i know that if i had shoot a deer and it ran onto another persons property and died, i would feel that is was my obligation to retrieve the deer. i'll say that i would be angrier that someone left the deer to rot than seeing them on my property without permission.

and last but not least. why wasnt mod out hunting?
