Another riddle

Two police offers were investigating a mysterious death. When they arrived at the scene of the crime they found a room with no windows and the dead man who seemed to have hung himself by a rope from the ceiling. There was no chair or table that the man may have jumped off. The only clue was a puddle of water on the floor. How did the man manage to hang himself?

This one pretty easy,

he stood on ice, and it melted...old

He stood on ice, then it melted.

HE COULD'VE STOOD ON A BIG BLOCK OF ICE

YEP! A BLOCK OF ICE .
