Upper body stabbing reminds me of what I recently saw on an ID show about the Connecticut Valley serial killer. He did nothing sexual, just stabbing - profilers felt stabbing for him is actually something sexual, so in that sense he is committing a sexual attack.
orm of sexual attack. This killer took his victims shoes (have to double check that), correct me if I'm wrong (anyone?).
He stabbed multiple times, upper body. I do not believe this SK is actually related to Mary murder, just his profile.
How many times was Mary stabbed (sorry to ask)?
Wonder if anything of her's was found missing since SK usually take trophies.
ETA - here's a link to the show I was mentioning:
