Large Buck in West County

So im out spotting last night and I came up on this field. As soon as I flashed the field about 30yds off the road stood a very very impressive 10pt with 2 stickers prolly 18-20" spread very tall rack. Anyhow right behind his right shoulder is an arrow with 2 red and 1 white fletching sticking about halfway into him. It appears to be just below the spine and above anything vital. Given the angle of the arrow it appears to be a ground shot. Dont know if anyone hit a deer matching that discription out this way. He doesnt appear to be too badly damaged by it but may not make it to rifle season with the arrow in him still. Just thought id throw it out here as I know id be sick if I shot him and couldnt find him. In the heat of the moment I bet it looked like a hell of a good shot.
