Case frame
The public timeline is precise; the explanation is not.
Official sources document Kyron’s science-fair attendance, the last reported hallway sighting, the missed bus, and the escalating response. They do not establish what happened after the school sighting.
Research boundary
Check sources. Do not intervene.
Do not treat civil allegations, commentary, or repeated online claims as a criminal finding. Use MCSO or the FBI for current case facts and any firsthand tip.
