Easy guys. He didn't know he hadn't put the kill shot on him. If I see a deer go down right off the hit, I'm not gonna expect him to jump up and run off after hitting the ground and kicking like that. I would have done the same thing. I would have watched for him die right there. Easy tracking job! It's just bad luck is all. I'm sure you killed him. If you did a proper search (which you said you did) then you did all you could do. Ethically speaking I think you did nothing wrong. Even pros have this happen. Last week I watched it happen on Bone Collector. They gut shot a deer and found it like a month later. Like I said just bad luck man. Sorry.
