Thanks Bessie, I will take that as a compliment coming from you. As I said, the theory was strictly for the purposes of seeing if it was logistically possible, the motive is another thing altogether. And I agree, that it would likely be equally easy to kill DM, but then, the killer wouldn't have the cover of having another suspect to pin it on, and would have to be even more careful about the disposal of evidence. This way, at least, when a small piece of evidence doesn't match the DM is a killer scenario, it is outweighed by the larger evidence of the truck and body to make it seem more insignificant and less relevant, whereas if the killer killed DM with no fall guy to blame it on, the police would have to seriously consider all the little clues with the same gravity in the search for the killer. In my opinion, when LE are handed a suspect that looks good to them, they don't waste their time and our money looking to see if there is a better suspect, they spend their effort looking to find things that confirm their suspicions and strengthen their case, that is their job. Therefore, looking for and finding evidence that weakens their case is ultimately counterproductive to their cause, logically, which makes me honestly suspect that small clues that don't match are more likely to be swept under the rug along the way, in what is considered to be the advancement of justice by well-meaning LE.
Or it could have been better to frame DM than to kill him if the murderer turns out to be a friend of DM who would naturally be considered a suspect if DM were murdered, but never thought of twice if DM was instead framed.
And personally, I would probably prefer a clean death to wasting the rest of my life rotting in a tiny cell with my every action restricted. If you really, really, hate someone with a vengeance, and you kill them, they are dead, they feel no pain, the only ones you are hurting are those who loved them. But if you instead could submit them to a lifetime of hell for the same amount of effort, I can see a killer finding that appealing.
I think that as far as motive goes, an equal or greater amount can be made for framing DM as could be made as a motive for DM killing TB, but that neither cancels out the other possibility completely.
