Thanks for summarizing a coherent picture of the pieces we have been discussing. Floating theories and then trying to poke holes in them is one of the parts of Sleuthing that I enjoy best.
I'm not able to poke any holes here, not just because I agree, just not seeing anything in the facts to refute this.
@divineappt was thinking this photo may have been a diversion to make it appear everything was fine. That's possible.
Now, at the same time, additional observations.
Will agree that AxC looks bored as can be. After seeing how calm he was talking to LE just minutes after murdering CV, I'm not sure anything would frazzle him.
Yet, If you had children and had just moved with in a 90 minute drive of YNP, it might make sense to go there (for normal people).
At least from the perspective of getting the children to be more or less compliant for 90 minute drive.
Ok, there are those that think this trip may have involved some sort of "hand off" of TR.
I'll entertain that possibility...
In that scenario, I see 2 kinds of "hand offs", one being "For her own good" and the other being "outright evil".
#1 might include an arranged marriage, weird stuff in the sub-cult, etc.
#2 might be selling her to a cartel or other hideous possibilities where she was guaranteed to not surface again.
For #2 the odds of seeing her again and consequences are essentially the same as if AxC and LVD killed her themselves.
So, just looking at #1, phone records and associations should have borne that out by now.
Unless the FBI is on to some hot lead there, this no longer seems plausible to me.
My guess is that after this photo was taken the only trace of TR was LVD's use of TR's accounts.
Between CV's murder to this photo there as a systematic severing of the Children with the outside world, including family.
There were stories and deceptions planted right up until JJ vanished.
Considering there is ZERO proof that TR was alive after this photo and JJ after the ring cam video, that all points to 1st degree murder.
If there was life insurance on the children, I would hope that is blocked.
Another thought is that what if on this trip, JJ and TR were being told that TR was going off to school the following day?
It would be news to TR... what would be going through her mind? Terrified? right... think about that and then look at the photo again.
Method:
Would AxC be wanting to end TR's life quickly?
Or was he wanting to make her suffer?
(Note, if AxC is the one that murdered at least one of the children, I have no doubt he killed his sister... and that means he probably murdered other people in the past too)
I'd go with fast. Why not drug her? Choke hold. or something along those lines.
He could easily use a gun, but ballastics match or not, that would point to him because of CV's public murder.
What would be the simplest, least risky, because that is the theory I would go with?
Same with JJ, most likely drugged at least to the point of complete unconsiousness and/or poisoned.
Truck? What truck? Is it proven that AxC used his rig for this trip? That would open up other possibilities.
Or was it LVD's or AxC's normal ride?
Bodies:
There are endless miles where it might have went.
But, since AxC isn't so bright, it may have gone to some place convenient.
A scenic overlook? Off the side of a bridge over a high ravine?
Dragged into the woods or dropped down a mountain side near the road?
How many people searching for how many years would that take?
Bodies do turn up, but out there it's about as hard as it gets.
Let's say she was alive but unconscious when they got home...
In that case, she might have been finished off at AxC's place
but again, nothing messy, no blood or body fluids.
Hey, another reason for removing a car seat from the back of the jeep could be
for a container with a body in it. And that container could have been buried anywhere
in the nearly 1,000 miles between Rexburg ID and Chandler AZ.
Maybe there are other storage units in other names. Maybe there is a 55 gal plastic barrel with someone in it buried out in the desert.
Statistically most bodies are found not far from where the murder took place.
But you'd have to have a good idea where that happened to even look.
If you knew exactly what vehicle they had and the YNP cam captured them leaving with TR in the vehicle,
what LE should be asking for is if anyone saw that vehicle stopped along the road, etc.
For JJ, it seems mostly likely he was murdered right there in Rexburg or maybe went for a ride with uncle.
Same thing... some kind of container... most likely buried near where it happened.
The neighbor that helped them move in, did she see or help them bring in plastic containers with their belongings?
If CD were involved in the body disposals it gives many more possibilities.
I think that however the children met their end that it's possible LVD does not know where the bodies went.
So she has nothing to trade for leniency.
Criminals can't think of everything, and so the FBI might be able to find a flaw that leads to at least one body.
Note: Paige Johnson's body just turned up after 10 years!
