 In which case we count incapacitation as a win. But in all likely hood if Dunn was sunk to the bottom of a body of water for a few days and fished up cold to the touch no one would try to revive him. As such his body will never become warm enough to function again and even if it did somehow get warmed up it just wouldn't start up on its own. There would need to be some kind of electrical stimulation of the heart and brain to get him running again. So he'd be dead in every sense of the word just potentially able to be raised.
