I would be willing to say you gut shot him becuase his actions are typical of a gut shot deer they usually take off running when shot and stop then start walking. I would look around the thickest cover and also the water sources the acid from his guts will start burning his insides and he will be looking for something to cool it. And dont jump on this guy he prolly got excited when a deer comes in you forget what time it is he didnt say it was dark he said it was getting dark.
