No cause was found for Tri-Rivers students who complained of breathing problems.

The Marion County Sheriff’s Department was called to the Career Center just after 11 AM Friday morning after 4 students reported problems breathing and headaches.

The First Consolidated Fire Department was also called in to test for poisonous gas. None was found.

The students, along with a teacher, had been in a classroom for several hours of testing. They later moved to another room.

The students recuperated after some fresh air.
