Just now catching up on some of the background of this case. Obviously, SP is a very creepy, very sick man. Would it surprise me if he had anything to do with Susan's disappearance? No. What would shock the you know what out of me is if JP had nothing to do with it. Midnight camping trip with two small children in sub-freezing temperatures? The goal of which, according to him, was to make s'mores?! Not showing up for work the following day, without calling in, because he lost track of what day it was?
No person with any shred of a brain in their skull would believe that horse spit.
