The police finds the following scenario:
A man is hung up in the middle of a room (like in the movies, with a rope and stuff). The room has only one door, and no windows. There is NOTHING in the room except for the rope and some water on the floor. The room is in the middle of a desert, where nobody lives. Apart from the truck he came with, there's only 30 miles of sand to every direction of the room
The police assures that the man has been dead for a couple of hours and that no one else has been in that room for at least a couple of days. Of course, he couldn't have hung himself by jumping or doing something like that.
So how did the man actually die??
