Why are drunks called in as dead? Usually it's shopkeepers or property owners who do this. "Well, he looked dead to me" is at least vaguely plausible providing the drunk isn't snoring, and corpses are picked up almost as quickly as the profuse bleeders. When they turn out not to have actually completely gone off the use of other people's oxygen, they're nevertheless whisked away to -- and this is the important bit -- somewhere else.
