The armory — which holds classrooms for UNC's three ROTC programs — is kept locked and contains active and inactive military-issue weapons, McCracken said. He mentioned parade rifles specifically.
The original 911 call came at 8:22 a.m., McCracken said. The Alert Carolina went out at 8:53 a.m. according to the alert website.
