"There have been no threats, but we were just being very cautious," Dr. Yarbrough said.
The ammunition found was bullets for a high-caliber .223 rifle and a .32 handgun. Seven bullets were found.
During a lock-down, no one is allowed to leave or enter the building, and all students are confined to their classrooms and not allowed in the hallways. Dr. Yarbrough said the lock-down was lifted about 9:15 a.m., after a thorough search of the building. After being notified of the custodian's discovery Thursday night, Marion Police conducted a thorough search of the campus.
This morning Marion Police officers were stationed at each entrance to the schools during the lock-down.
