Back when Chris/PE was talking about the cars, I had a theory that I wish I could fully remember.
But it was basically that the cars themselves weren’t important, as they’d all be expected to be at the PP home, but it was how they were parked. My guess is that no cars were parked in the garage and instead they were all parked in the driveway, with the suspicion that BM pulled a vehicle into the garage to load SM’s body covertly, and never parked the cars back in the garage. Perhaps it is odd that a nice black Range Rover that is always in the garage, wasn’t in there when LE showed up.
Somewhat related to that theory is that the pics of the PP home when BM put it up for sale, did not include pics of the garage, mud room entry or kitchen. So it made me feel like those rooms were really important and possible completely torn up by LE.
