Are you sure you hit him? If you missed or wounded him, they will swim off underwater and crawl out somewhere else; perhaps where you can't see him.
Did you use hollow point or ball ammunition? .223 is high velocity and can cause just minor wounds with jacketed ammo (if you don't hit any vitals). I like to shoot for the water line, so that if I pull the shot a bit, I will still make a hit.
