A couple checks into a hotel and have to put up with a foul odor in their room all night. They call the staff to complain and somebody figures out the stench is coming from the bed.
Now, there's no way that scenario is going to have a good ending. You're almost hoping at that point that it'll turn out the last guest just got drunk and pooped behind the headboard. But, no, the staff take off the matress and discover the couple has been sleeping over the rotting body of a dead girl who had been stuffed in the box spring.
This actually happened, in Las Vegas. Also, Kansas City, MO and Atlantic City, NJ and several times in Florida and California and, well, let's just say that in or under the bed in a hotel room seems to be a fairly popular destination for the recently deceased.
It makes sense if you think about it. The closet and under the bed are the two most popular places to hide just about anything, so it's not surprising a hell of a lot of corpses end up there as well. In fact, the odds are pretty good that at least once a guy has killed a prostitute, tried to stuff her under the bed, only to find there was already a body there.
