Guy was the top of the suspect list for over a hundred years, now they find his semen on the same shawl that had cartoid artery blood spatter from one of the victims.
He is then interned in a nuthouse, and the murders magically stop.
Yep, he must have slept with the victim, spunked on her shawl (all prostitutes wore scarves in bed lol) and then she happened to have been slashed to death by someone else, whilst wearing her favourite BJ Scarf lol
