I have been trying to reach the end of this thread all day! It just keeps getting longer and longer. So I give up. Sorry if this has been posted already, way on down the line.
Several have mentioned getting a 'Balloon Boy' feel from this case. I have felt that too. Also mentioned has been, 'follow the money.'
This case has felt weird from the start, leading some to wonder if it is a hoax of some kind. Desiree's distress seems authentic to me. Tony's concern for his wife and for Kyron seem authentic. KH seems very stoic. Still not sure how authentic that is. TH seemed like a frightened animal. To me, it wasn't grief and it wasn't concern, it was fear.
So if this was a hoax of some sort, I don't believe it involves more than one of those four people (possibly 2 but I think more likely 1).
We have reports that there was a 'murder for hire' plot several months ago. Now Kyron is missing.
So going on that (MOO only):
1) Plan A, hit put out on KH for insurance money. Lawn guy doesn't bite and it falls through.
2) Plan B, hoax kidnapping for ransom. Partner takes Kyron. Ransom is delivered. Partner and TH divide ransom.
The money is the only thing about this case that makes sense to me. It would also explain the 'Balloon Boy' vibes.
And this is why Desiree says 'Kyron is alive' with such conviction, why she said 'we thought he'd be home by now (paraphrase), and, why she implores with TH to cooperate.
