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?
Speculation is she dumped him before this incident. He may have deliberately reserved the room in her name to associate her with the attack as a sick way of "getting back" at her in revenge for her leaving him. He'd be dead, but the FBI would be tracking down and arresting her.
Unfortunately for him, the cops bought her alibi.
