I think they are waiting to see if Deorr's body is found before filing charges. Once someone is charged, the clock starts ticking for the defendant's right to a speedy trial. If LE presses charges now, discovery process starts. LE must turn over to the defense whatever evidence they have. If the evidence is largely circumstantial, and not lots of forensics, or hard evidence, a jury may find the defendant 'not guilty'. Say a week later the body is found, and there's evidence of a murder, or Deorr is found living with someone else, well, charges can't be placed on them. They wouldn't be able to retry them just because new evidence is available.
Thus in several cases I'm following right now, an arrest hasn't been made because time is on the side of the state or prosecution. In several cases, the belief is the victim is deceased, but haven't been located. LE realizes they can't save the victim, but they can wait and hope for more evidence to have a more solid case in court.
I'm still not convinced that DeOrr didn't wander though. There's been way too many cases where drones, dogs, LE, and multiple searches have found nothing, and then an everyday citizen finds the body. There's been cases that a body of water was repeatedly searched, LE convinced the body wasn't in that body of water, only for a fisherman, or someone else to find the body months later. (Biggest one I'm remembering is Teleka Patrick. That small pond right where her car was located. It was sonar searched, and multiple searches. Yet months later, a fisherman found her in that same pond.)
As grown up as those woods were where they were camping, and all the downed trees, briars, rocks, etc in the area, I'm not convinced his small body couldn't still be there. Possibly even within yards of where searchers have searched.
While an abduction seems impossible, I don't think it can be completely ruled out either. I just watched some youtube videos of different cases, and in one, there was a 3 minute time frame in which the child was abducted!! THREE MINUTES!!!! Granted it was a child waiting on a bus, and on the side of a road instead of the wilderness, yet it happened. There was also a case where a stranger scoped out a home, killed everyone but the two children, and abducted them, he had them both at a campground, and killed the little boy. The little girl survived and was seen at a pizza place I believe it was, and the waitress recognized her, and called police. Shasta? I think. People were stunned it was a stranger!
I also haven't ruled out the parents are involved. I truly just don't know what has happened to DeOrr, but think of him often. One day I hope we have answers!!!!
JMO!
