Wow, so many possibilities however unlikely. I sure hope this little guy is found soon, as everyone here does.
Taken by a mountain lion? I discounted that theory early on. But it was just explained that dogs are afraid of and won't follow the track. If this is true, this lends credence to this theory. Gone without a trace, or gone without a tracker?
Drowning in the creek or reservoir. I don't think so, as they say they have raked through there and even searched holes. No, his body didn't come to the surface within the expected amount of time...3 weeks. But it's possible, but probably unlikely, that he is caught up in some ratty logs or branches.
Abduction? I REALLY don't think so. No scent. No information about anyone else camping in the immediate area either.
After seeing IR's interview, I have a pit in my stomach wondering if drug use had anything to do with this. I find it hard to believe (my opinion of course) that the parents didn't know IR before they went camping. If I remember correctly, they went to GGP's favorite camping spot. How long has it been his favorite spot? JM and Dad Deorr seem like the outdoorsy type (camo clothing, ATV). If GGP loves camping so much, how often did he camp, and how often did JM and Big Deorr camp with him? The parents said they were at the site for the first time. Yet it seems, knowing GGPs physical and mental deficiencies, they would go with him sometimes. GGP and IR's relationship doesn't make sense to me either. GGP is about twice the age of IR. <modsnip> It's a little unusual, to me, that a guy of that age likes to hang out with a senior citizen whose health and mind are failing. And after the seeing the interview with IR, I suspect his mind was altered and that it probably often is. Wouldn't he be camping or hanging out with people his own age, reputable or not? Is he more of a caretaker of GGP? How often do IR and GGP spend time together? The whole problem with this is there is not a trace of Deorr, so I don't think neglect, even if there was any drug use among any of the 4 adults, plays a part in his disappearance. What I have thought since the beginning is that he probably was never at the campsite to begin with. Again, substance abuse? What if there was a drug deal gone wrong and they knew who had him or who has him still, using him as a pawn. I don't think it's too farfetched, nothing really is at this point.
Another big question I have is, ASIDE from family and IR, WHO PHYSICALLY SAW DEORR last and when? It is possible that Deorr was missing for a number of days, for all we know.
Sorry I'm regurgitating much of what has already said, but as so many have pointed out, there is so little to go on. Who knows what is happening behind the scenes, or if it ever will be solved.
