I still wonder - could this essentially be a custody battle?
TH has raised this boy, and as a stay-at-home-mom, could well be closer to him than Kyron is to his father. However, as a step-parent, she has no legal standing - if she were to divorce, it's almost certain that either the father or the mother would get custody. If TH felt that a divorce was imminent, she might have taken Kyron and stashed him somewhere well out of the area, perhaps with a friend/boyfriend/family member. It's not impossible that Kyron might even have gone along with the plan willingly, if he were very close to her.
This is my first time posting. The time line on June 4, 2010, 8:45am until 3:45pm would allow someone 7 hours to travel quite a distance. It was posted (couldn't find the link) that an airport is only 15 minutes away; however, there hasn't been any reports of passenger lists being checked for an adult travelling with a 7 year old boy. It seems the focus of this investigation is just too narrow right from the beginning. moo
