I don't think they thought he ever left the body at the house. I think they figured he got it out of there almost immediately.Well, if it happened as MPD theorized, the body was in the house long enough to be bagged and wrapped. I thought the theory then was that he immediately took the body to the warehouse, put it in the boat, got the anchors, etc., and away he went. So, the boat at the warehouse was the only place they needed the cadaver dog to check, right?
Don't know. We never saw what they did with the vehicles, of course. If she was in one of them, wouldn't the cadaver dog have hit? But then, we have Baden saying that if the body was well-wrapped, it wouldn't have left much of anything for the dog to find anyway.
