Aalia's Suicide Case

Riddle 
Aalia is discovered hanging four feet above the floor in a room. There is nothing else in the room except a large puddle of water beneath her. The police are stumped as to how she could have climbed on to hang herself. Did she commit suicide, and if so, how did she do it?

    She stood on a block of ice and put the noose around his neck. Once the ice melted, she was hung, and all that was left was a puddle of water on the floor.
