A bomb threat at Carter Middle School on Friday turned into a medical emergency after at least 21 students were hospitalized with heat illness and at least three were transported in critical condition. School officials had moved the student body outside to Carter High School’s football field because the two schools share a campus.
Jeff Bagwell said the initial call came in at about 11 and that the school reacted as it should. But the response began to unravel as students spent about an hour outdoors, and some started showing signs of heat exhaustion and even heat stroke before being taken to care.
The number hospitalized shows how quickly an evacuation can shift from a security measure to a health crisis when children are left in heat for too long. The students’ current conditions have not been confirmed, but the scale of the response made clear this was not a minor disturbance. Rural Metro Fire said agencies from Anderson, Blount and Grainger counties joined the response, while school nurses on the field helped evaluate and treat students who became sick.
Bagwell said the students were safe and were never in any harm or jeopardy, a line that sits uneasily beside the fact that multiple students were rushed to hospitals in critical condition. Jon Rysewyk said students were given water and shade while outside and praised Carter Middle staff, but he also said the system would be reviewed. Knox County Schools said it would look at what happened Friday and may update how evacuations happen in the heat.
Authorities said a middle school student reported a written threat, and the Knox County Sheriff’s Office cleared the school while continuing to investigate. Parents were notified when the building evacuated and again when the school was cleared, and JD Overton is expected to reach out with a follow-up after Friday’s response. The unanswered question now is not whether the threat triggered the evacuation, but whether the district’s next procedure will keep a security drill from turning into another medical run to the hospital.
