No, you aren't the only one who had that run through your head. I thought the same thing. What do you REALLY think he did with her??
I don't know. So far it looks like he wrapped her in the cut-out mattress top and took the body somewhere. Could have driven the body anywhere, dumped it anywhere (land, lake, river, etc.) I'm just puzzled by the thought that he suddenly has a truthtelling attack. Doesn't usually work that way. Do we know where the gun is?
I think he cut her up into pieces and has scattered them all over the remote canyons within close driving distance of SLC. He has mis-directed the LE officers to the landfill while the pieces of Lori are picked clean by the predators.
He has been diverting attention from the truth his whole life. It is second nature to him.
