The only reason a guy like this goes nuts is a woman.
Money did not seem to be an issue, he seems apolitical.
Random thoughts: Did this Danley couple groom him for this? How long have this Marilou and Paddock been together? Where did they meet? How was she tied into this in the first place, for the police to call her a person of interest - because her ID was used to secure the payment for the room? (which is what I thought I read elsewhere). If so, why wouldn’t she want to hide her association with him, why would she leave her ID wothbthe hotel? Could these Danleys and Paddock be a connection between Mideast terrorists and Antifa?
