It's not impossible. Great Grandpa has "mental issues" per the sheriff's department. As I said, he may believe 100% that he saw DeOrr there if JM and DK told him he was there.
IR supposedly didn't know them, they had supposedly never met before this trip. He wasn't planning on hanging out with them, he was planning on fishing. He wasn't paying that much attention to them.
They arrived at the campground in separate vehicles, at night. If JM and DK said little D was asleep in the truck, neither of the other two would question that. Then GGP went to sleep in his camper, IR went to sleep in his tent, and JM and DK slept in the back of GGPs Suburban I believe.
Next morning, IR goes fishing. GGP is doing whatever. JM and DK leave for town. The other two aren't concerned where little D is, knowing he's with his parents.
They come back from town. IR is fishing. GGP is told little D is there, but like I said this could be manipulated.
It's not an unreasonable scenario. The scent dogs didn't track him at the campground. They should have been able to. Most 2 year olds would have been running all over the place.
We only know for sure about one diaper, and there's no proof it was even little D's. The sheriff said he was 99% sure little D was at the campground, but that also means he is NOT 100% sure. Even the sheriff has doubt.
No trace of him was found at the campground other than items the parents provided.
This scenario is NOT concocted by 4 people. This scenario would be concocted by 2 people responsible for whatever happened to cover their @sses, and the other 2 are innocent bystanders who have no idea what actually happened. I think IR and GGP have been truthful with the sheriff. Notice the sheriff has also never said that IR said he'd seen little D there, and he said GGP's info was unreliable due to the mental issues.
Please post a link that the sheriff's department said that GGP has mental issues. TIA
