Twenty-one students were hospitalized after a potential bomb threat forced an evacuation at Carter Middle School in Tennessee on Friday, September 4. Students were moved outside while authorities searched the school, but the extreme heat caused multiple students to develop symptoms of heat-related illness. Three students were reportedly in critical condition when they were transported for medical treatment.
Threat Discovered at Carter Middle School
The incident began shortly before 10 a.m. when a threatening message was reportedly discovered written on a bathroom wall at Carter Middle School in Knox County.
School officials evacuated the building as the Knox County Sheriff’s Office responded to investigate the potential bomb threat. Students were moved to a football field shared by the middle and high schools while deputies searched the building for possible dangers.
Authorities began clearing the school at about 10:25 a.m., and students were allowed to return inside at approximately 11:27 a.m.
Students Become Sick in Extreme Heat
While the students were outside for less than an hour, several began showing signs of heat-related illness. Emergency medical crews responded and began evaluating students who needed assistance.
Rural Metro Fire reported that 21 students were ultimately transported to Dolly Parton Children’s Hospital after experiencing heat exhaustion. Three were considered to be in critical condition when they were taken to the hospital.
Some students received treatment at a field house near the football field, while others were treated after returning inside the school. School officials said students had access to water and shade during the evacuation.
Knox County Schools Superintendent Jon Rysewyk said staff and emergency responders acted quickly after students began reporting symptoms. He also confirmed that all of the hospitalized students were discharged before the end of the day and returned to their families.
Investigation Into School Threat Continues
Officials said the evacuation followed established safety procedures, with law enforcement conducting a search of the school before students were permitted to return.
Emergency officials praised the school’s response and emphasized that student safety remained the priority throughout the incident. Authorities are continuing to investigate the threatening message and the circumstances surrounding the potential bomb threat.
The Knox County Sheriff’s Office said it takes threats involving school safety seriously and thanked school administrators, staff, students and emergency responders for their cooperation.
