I just had this horrible thought that this whole thing was premeditated. Mainly because crimes of passion leave evidence. I know there's a whole bunch of scenarios where evidence wouldn't be left, but the possibility that this was premeditated explains a few things.
1. why DR went missing so quickly after arriving in Durango.
2. why there seems to be no evidence
3. why no one in the family has been cleared
4. if it was premeditated, it explains some of MR's demeanor.
I also think that he must be in the lake. The story with the fishing pole would likely be a way to innocently explain why DR will be found in the lake - he got a new fishing pole, couldn't wait for MR to return to drive him to his friends, so he went to the lake to fish and had an accident. It's so simple.
I think if MR flew into a rage or had a fight with DR or alcohol was highly involved, there would be more information out there. Something would have been seen or mentioned. I also can't imagine a father getting so mad at a 13 yo he could kill him with bare hands, but I know it does happen. But if this were plotted calmly and well thought out, it explains a lot, and to me, is more plausible than other scenarios that MR got homicidally violent.
also, if it were premeditated, the perp would likely feel justified in his involvement and he'd maintain his lack of sense of guilt. If MR flew into a rage and killed DR by accident, he would be having some psych problems and guilt issues that would expose him in some way.
but who knows.
