How Do You Know When Someone's Dead?

Heather West's body turned cold and Fred noticed she had wet herself. He then doused her in cold water in an attempt to rouse her. But he'd only ever seen it performed on television and didn't actually know what to do. So he tied a pair of tights around her neck, as he didn't want her looking up at him while he worked. Then cut Heather's neck with a serrated sore used for cutting ice blocks and frozen meat. The same thing was done to her legs before stuffing them into a bin liner. That night, under the cover of darkness, Fred buried Heather's body in the back garden.
