The strangest part isn't that the bodies wind up in such a terrible hiding place (killers often aren't the type to plan ahead). No, the strange thing is that in almost every story people will sleep part of, or in many cases, the entire night, on top of the corpse before reporting it.
Most people we know will complain if they detect that someone might have smoked a cigarette in their room four months ago. Not these people, they slept inches above an oozing heap of rotting human flesh rather than inconvenience the hotel management by asking for a new room.
Or, at least we hope sleeping is all they did on that bed. Oh, man, can you imagine dying and then the first thing that happens is some middle age couple starts porking over you? Ew.
Hopefully they at least got a free continental breakfast out of the ordeal.
