I've been thinking about it, and I think LE knows what is going on. This couldn't be some random person that threatened the community still because going silent about that would too dangerous. They can't risk some random person stealing another child. I'm thinking that's why they said it was an isolated incident - not a random kidnapping or snatching, but something that's once a lifetime and probably wouldn't happen again for some reason.
It makes me think this is some kind of specific kidnapping for ransom, or they already know who the POI is and it's someone that for some reason, they think won't go and snatch another kid. I would also think they wouldn't keep things this quiet if they had no clue because again, not telling the community that there's this dangerous person still out there puts them at risk. If they keep this close and another kid were to go missing, that would be horrible. But they're convinced that isn't going to happen, so saying nothing makes perfect sense.
But do we know that they haven't told the community something and just not told the press? Probably not because someone wouldn't be able to keep their mouth shut, and the perp might move on if they suspect the community has been warned.
I also don't think it's a wandering off because they seem to have a specific idea of what areas to search and what areas not to search. It's like they not only know the POI who did this what specific path they took. It's like they're trying to catch up with this POI and stop them. Reminds me of those movies with the diabolical kidnapper that keeps giving cryptic clues and very specific directions that if not followed to a T, someone will get hurt or a bus might be blown up, etc.
So they know it's an isolated incident with a very specific path, so specific that they're sure of where he's not. The know the family is not involved, and they know that no one else is in danger from this POI. Makes me think it is a specific threat of revenge against one of the parents, possibly the dad. Maybe one of the "rules" to getting Kyron back was having to do normal things like go to the gym. Maybe this POI is so diabolical that they are
I'm thinking once he's found, dead or alive, we'll finally understand clearly the reason for the silence, and I bet we'll be so glad and relieved that LE knew exactly what they were doing by not releasing many details to the media. At least I really hope so, all IMO, of course.
