But here's a HUGE problem with this theory. If he truly believes he will have all the following evening to carry out the rest of his plan (dumping body etc.), then there is NO REASON that night, when his wife might awake at any moment, to take the time to create all the "staging" evidence. Should Patsy catch him in the act of doing all this staging, he'd have some serious 'splainin' to do. All he needed to do was stow the body, because remember, your theory requires that he assumed no one would ever find the body in the house.
