She watched him walk down the hall to his classroom. At least that is what the article she says.
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.
