I also started following during TB's disappearance, well before anyone had any inkling of who was behind this.The things that make me feel this was a premeditated murder are the burner phone and the incinerator.
The burner phone doesn't really mean much for me. The incinerator doesn't really point to any one person either , JMO
I don't understand, if DM is "100% not guilty", how he got in so deep to this. Say DM went with MS to test drive a truck, and he totally doesn't expect anything else, but MS somehow kills TB. Why would DM not just get in his Yukon and get the heck out of there? Leave MS and the mess he created (hot truck, dead body) and don't look back?
Something called repercussions comes to mind her for me. For all we know there may have been someone else involved. Until we know who was actually involved, I think maybe more than the two accused. When people are threatened or scared they react accordingly. I think DM would have had a hard time leaving such a scene without others who may have been present.
Instead DM ended up assisting enough that if he were not charged with first-degree murder, he would face accessory after the fact to murder charges.If what CN did helped MS escape just as well as DM, I expect her charges would also remain.What kind of defense could DM possibly offer, that wouldn't make him face as-serious charges?
All allegations, there are a few possible scenarios. IMO
