A substitute teacher died Friday morning at a Prince George’s County high school after suffering a medical emergency, according to a school official.
Max Pugh, a spokesman for county schools, said no Largo High School students were in the stairwell when the man collapsed about 7:45 a.m., just before the start of school.
A vice principal called 911, but emergency workers were unable to revive him, Pugh said.
School officials said the substitute teacher had worked for the school system since 2003. Friday was his first day at Largo.
Pugh said the school will send letters home with students about the incident. Students were kept in their first-period classrooms until 11 a.m. after the medical examiner came to the building.
The school system did not release the substitute teacher’s name or age. Officials were waiting until the next of kin were notified.
