If rigor had not set in yet, then that is a fresh kill... 2-3 hours ago. It doesnt look like a lot of blood on the meat, so I'm guessing that rigor has past.

And I'm guessing that a car hit him, and someone dragged him off of the road.

*BTW, thats amazing that the deer made it 30 yards... that deer musta had a shot of adrenalin to not die on impact!
