for a long time I thought DR was there in the morning but deceased. I now think DR was killed in the campground and disposed of in the lake, so I doubt he was on the couch in any state of being. Unless DR was wrapped in something and was on the couch while MR was doing whatever he did to prepare to dispose of him.
we don't know if cadaver dogs went inside MR's house, do we?
i do NOT think DR was alive Sunday night at MR's house. When MR said DR was "out like a light" I really thought that meant he was there - dead. But now I'm not sure if DR was ever on the couch. did MR keep him overnight Sunday night in remorse/denial or hoping he'd "wake up" or for some sort of goodbye ritual and then dumped him in the lake prior to 6:30AM monday? or is he more of an Austin Siggs and needed time to do whatever he did before disposal?
I think MR is more diabolical than we think. I think the depravity could go very very deep and this was more than a fit of rage, or crime of passion.
