Interesting idea. He certainly had no concerns about tracking her blood all over the house even after the murder.I sometimes think he killed her at the condo because he hated that she had a condo. Or maybe just convenience.... if he really had no emotions, would he be so volatile and nasty?
I had always thought he just didn't care because it was KK who had to clean up but maybe he was also showing his resentment for Kelsey.
He killed her in such a violent way, in the one place she felt comfortable and safe with her baby, and then made sure to leave her blood over almost every inch of the house.
Imo
