Please note that TP said that Kyron was noticed missing when the class was re assembling after their tour, not before the tour of the other classrooms, if this was the case then there should have been other children, not to mention the chaperone for Kyrons group, that saw Kyron long after Terry had left the school, sorry this never happened.
One of the reasons that the FBI and LE asked TP and his grandmother not to talk to newsmedia about this story, not factual accounts, or some of the other students, sub teacher, that has been said was not the case, and Kyrons teacher would have backed this up.
TP [modsnip: change name to initials] sounds like he got the chaperone and Ms. Porter down perfectly, in my opinion.
The fact is that no one knows what those other children told investigators. They may have backed up every one of TP's statements, but LE asked them not to tell anyone. And we know that LE basically asked everyone not to talk and have continued to do so throughout the investigation. Why do you assume that they are being silent because their accounts don't match?
If you're implying that TP is confused between assembling before the group tour and reassembling after the tour was over, then why did the chaperone do a head count and get so upset that Kyron was missing, and then leave after being assured by Ms. Porter that he was around somewhere? Plus we also know that TP ran into Kyron on his way to see the "electric ones" and that Terri was not around.
