He participated in the Science Fair, his presentation was on Tree Frogs, so he was at school at some point.
When my 18 yr old son was 9, someone entered their elementary school, he was hiding came out of nowhere and brutally attacked my son’s classmate. He beat her in the head with a claw hammer in front of all of the kids as they were returning from the library, walking quietly single file. He then fled with the claw hammer still embedded in the little girls head. This was an extemely small school, less than 500 students total from K-5th grade in the middle of a residential area.
With parents in the school milling around for the science fair, anyone could have slipped in and hid in the bathroom. The poor child could have stopped on the way to class and was grabbed there.
What happened to that little girl and that monster?
The guy who did it was mentally ill and did not take his meds for a while.
The teacher who was wonderful, was never the same after that.
She had lost some of her motor skills initially but was back at school the next year, with an assistant. She just graduated HS this past May :)
