I think it was murder by stranger/s up on the mountain. (Not because there is so much proof, but more because there is a lack of proof for the other theories.)
Not murder/suicide: truck found parked weird, coats, food & dog in truck, why go into the mountains, both DC & PC reported general happiness (like upbeat and chatty)
Not murder by others: I don't think they were all that close w/their families. I don't know how the uncles would've known where they were. Same for handyman plus he was supposedly cleared by police.
Not lost or death from exposure: If they went for a walk, I think they would've parked better, like at the plateau and not the road. Found too far for Bobby & Madyson to walk. Not lost because they most likely crossed roads and/or water. Bodies found together. Truck seemed in working condition.
Not drugs or drug deal related **that actively involved Bobby & Sherrlynn**: their child was there, no evidence of drugs anywhere (and there would be at least residue). I can see why the large amount of $ raised eyebrows, but we know about the settlement (probably receipts or lawyer papers).
I do go back and forth with them being taken by force or not. I keep going back to the dog and why wasn't the window at least cracked open a little. I get the doors being locked because of the dog and money (at least one of them, probably Bobby, knew it was in there). Sometimes I think they may have gotten up to the plateau area on the 9th and either ran into bad guys doing bad things or were there & bad guys came across them. Maybe they tried to leave and were blocked in by other cars or even 4 wheelers. Other times I think it could be the helpful local that offers a tour and they never come back.
Unless there are bullet holes in some of the bones, I don't think we will even get a cause of death. After hearing/reading about the OK ME's office, I'd be pleasantly surprised if we hear anything w/in 6 months or even a year.
I can only pray that whatever happened up there, it was mercifully quick. And I pray for justice.
But sadly, I don't think this case will ever be solved, unless there's a miracle (like witness comes forward or some kind of super great evidence left at body site, which seems unlikely after 4 years). I could be wrong, but I don't think LE is very invested in this case at all. Sheriff #1 Beauchamp seemed very sincere in the Disappeared show (also, super cute!). Sheriff #2 Brooks seemed like he decided they were drug dealers and that was it. #3 James I don't know anything about but haven't heard/read about any new avenues to investigate or tip lines or anything else to get the public's mind back on the case. (This leads me to a rant about how uninterested the family (not NS because I think she tried somewhat) seems to be. No reward--weird. $ was available. Pushing away help from SAR. If it was me, I'd be calling LE all the time. Same w/media. I'd do anything to keep the case out there. They'd be so sick of me. It breaks my heart that it seems like no one cares.)
Thoughts? I'm always open to new ideas and changing opinions.
