I have always suspected that DeOrr never made it to the campground due to the fact that no trace of him has been found - no scent, no toys, no boots, no nothing. It's as if he was never there because he never was there. Previously I was of the opinion that he may have died on the drive up to the campground or sometime in the middle of the night Thursday/Friday, but I am starting to lean towards him being deceased prior to the trip. It seems that the parents did not pack toys (or apparently diapers) or anything else that a two-year-old would need for an extended camping trip. Therefore, I think he was deceased prior to the trip. I'm getting hung up on whether the camping trip was previously planned for Grandpa and Isaac, and the timing worked out perfectly for the parents to dispose of his body so they decided at the last minute to "tag along," or whether the whole camping trip was entirely staged from the get-go as a means to play out the disappearance. It's my opinion that Trina is lying about it being her idea for Jessica to go along to help her grandpa. I think it was Jessica's idea to go (knowing it would provide a way to stage DeOrr's "disappearance" - "hey mom, why don't DeOrr and Little Man and me go along with grandpa, just to make sure he's okay? That way you don't have to worry about him? I'm glad to go and help") and then she later told her mom to just tell investigators that it was her (Trina's) idea for them to go so it wouldn't look suspicious. I think Trina has said and done many things that aren't entirely true in order to steer the investigation away from her daughter and away from finding the truth (the diaper story, the camping trip being her idea, refusing a reward, not changing his eye color, befriending law enforcement, etc.) because she figured out that baby DeOrr wasn't alive and that her daughter was involved. I think she went into protection mode and tried to put out the social media fire. For awhile Jessica's sister played along too - claiming she saw video of DeOrr in the Stage Stop, for example. Jessica probably told her sister there was surveillance and to tell folks that she had seen the video, just to quiet the naysayers. I think her sister caught on pretty quickly and quietly distanced herself from the case. Trina is still at it. It seems she is now bringing up things like the EMT bag, the cremains, the unmonitored comings and goings of vehicles and people during the searching, etc. These comments seem to be undermining the investigation and suggesting that someone else could have harmed or taken DeOrr away from the campground (i.e. reasonable doubt). It seems she is now working on the defense, in case her daughter is ever charged.
As for what happened to DeOrr? If we believe that Trina saw him alive and well on Wednesday night (when Jessica was helping clean out the camp trailer for grandpa, not at that time thinking she was also going camping) then I think something happened to him late that night or on Thursday. If Vernal was truly away helping his boss move, then I am wondering if something happened to DeOrr under Jessica's watch. She then called Vernal and told him they HAD to go camping to take care of her grandpa and when Vernal got home, he realized why they REALLY had to go "camping." So, the question is, did they dispose of DeOrr around Idaho Falls (Snake River?) before they left on the trip? Did they put DeOrr in something and dispose of him on the way up to Leadore? Did they drive somewhere in the middle of the night (using up a lot of fuel) and dispose of him? So many possibilities. The fact that Jessica may have turned off her phone all night is a red flag to me. I'm leaning towards them doing something with his body in the middle of the night. However, that is a huge window of time and who knows where to start looking.
The biggest dilemma I'm having with all of this is why on earth Bob and Isaac claim DeOrr was there... that is a mystery to me.... It doesn't sound like the parents really tried to fool them by saying DeOrr was sleeping in the truck or anything like that. I think Bob could have been coerced into covering and lying if Trina requested him to do so (or convinced him that DeOrr was there, if he has memory issues). I don't sense that Bob would cover solely for Jessica and Vernal without Trina's involvement (and it's been said by LE that she's not a POI, although it is interesting that she was given a polygraph). I do think Bob could in turn coerce Isaac to cover for them, but it really makes me wonder why they (the parents) would add these two men into the mix when they could have just gone "camping" alone. Although if they were all alone, they would have to admit they were the ones not watching DeOrr and they couldn't place the blame on someone else. So, maybe Bob and Isaac were just puppets in the play. Whatever the case, it's certainly a twisted game.
ETA: The thought just crossed my mind that perhaps when Jessica was helping clean out the camp trailer, maybe Trina suggested to Jessica that she and Vernal go with Grandpa and Isaac and Jessica told her they couldn't go because they had other plans, but then when something happened to DeOrr, she called Trina and said that she had changed her mind and that her family would actually go on the camping trip? So, that would still make the idea Trina's but maybe Jessica didn't take her up on the offer until right before the trip?
Also adding that this is all just my opinions and thoughts at the moment....
