Thank you for hearing me out. I do appreciate that so much.
Yes, the end of the year talent show was attended by parents and children and Kyron was to perform:
Schreiber said Kyron was supposed to perform in the school's talent show at 1 p.m. but she didn't see him there.

On Sunday, agents and officers interviewed parents and students who attended a science fair and talent show on Friday, searchers worked into the night.

Just think about it, JBean... if SM had attended the talent show (and I would think that she would considering that she herself boasts of how active she is within the school), Kyron's disappearance would have been noted three hours early, while staff, parents, students, teachers were still on the grounds of the school. But, again, no one was alarmed that Kyron wasn't there for the talent show.
It wasn't negligence. The teacher wasn't alarmed about his absence. It if were negligence, she had numerous opportunities to see him missing. Gone for a drink of water? I don't buy that. She knew that he was not there, and she knew that he was not expected to be there. This is the detail that we don't have--the information she had that caused her not to be alarmed that he wasn't there.
Again, thanks for hearing me out.
ETA: There are elements that make me believe that this was premeditated, but I'll save that for later. I'll just say-- busy school, teachers preoccupied, parents preoccupied, someone had experience with events like this at the school, knew how it would be, and took advantage of the moment.
