According to the Kingsport Police Department, the third-grader brought a small kitchen knife to the campus, where it was discovered shortly after 8 a.m. The matter was immediately addressed by school staff, said Andy True, Kingsport City Schools assistant superintendent of administration.
Tom Patton, KPD public information officer, said the boy surrendered the knife to school officials and no one was injured.
Jackson was not locked down during the incident. Under normal operating procedures, True said, the exterior doors and classroom doors are already locked, and students remained where they were until the situation was resolved.
Soon after, the school resumed its normal activities.
Patton said the incident is still under investigation by school officials and law enforcement, who are trying to determine why the student brought the knife to school. No charges have been placed at this time, and the boy has not been suspended from school.
