I am getting to be more curious about the teacher.
1. The teacher reportedly told the parents that Tyron was not at school when class started, and that she had marked him absent that day.
2. Kyron's seat-mate told police that a substitute teacher who was about to be left with the class, noticed that Kyron was not with the class and pointed this out to the teacher, who told the sub that Kyron must be in the bathroom or getting a drink of water.
HuH?
Why did they need a sub if the teacher was there? Why was the teacher leaving? Was it a last-minute thing...did she leave the school, or did she just leave the classroom to work elsewhere in the building? Did she return to school that day?
Everyone has been asked not to speak to the media, and even this little boy did not speak publicly at first. It was only after the school's story of Kyron being absent was publicized that this boy's family decided to speak out anyway.
I think the "sub" was probably someone there to help lead the small groups around the science fair. Also, the little boy who told this story is the same little boy who told the news about being surprised Kyron wasn't on the bus. I think but am not sure that he's also the same little boy who said he saw Kyron near the south door. Sounds to me like he's trying to come up with helpful ideas, but maybe not so accurate.
