Found him. So did the coyotes. I was back out there when it got light. couldn't find another spec of blood after the last one we found and marked last night. My buddy came over and brought his kids and We followed all the creek beds then went back and just followed path of least resistance along a creek bed that headed down to the main creek. about 500 yards from the last spot of blood. At that point I decided to just walk a hundred yards or so down the main creek ( this is a small river about 50 yds across and 5+ feet deep in many areas. I saw him thru the brush about 50 yards up the main creek on the other side in the shallows. He has been torn apart on his back end. Most likely coyotes. There are not a ton of them around here but they are seen from time to time. The buzzzards are circling and won't be long off the carcass. Since I don't want swim across, I'm gonna drive down to the first house on the other side and see if they will allow me to go try to get to it. They may allow me. At the very least I want to inspect it to see where I hit it because most deer I hit drop in the first 50 yds. This one went more than half a mile. I need to check my crossbow and make sure I'm hitting where I think I am. I took a picture but it's a bit grizzly so I am not posting it.
