Handprints

"I am so sorry. Sorry you’re just like the others."

The only clue are the handprints. They tend to stay for a while. Always on the cheeks. There are no fingerprints, but bare hands were used. There are no traces, no clues and there has only ever been one sighting of a murder that fits the description.

And in that sighting, a neck was seen snapped, but there was no one else there to snap it.
