11:33 a.m.: McCracken said he does not think the police response was an overreaction given recent events around the country. He encouraged anyone who sees anything suspicious to report it.
DPS is trying to get in touch with the person who originally called 911, and McCracken said "it may well be" that the person thought they saw something suspicious.
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.
The UNC Eshelman School of Pharmacy went into lockdown at 8:35 a.m., according to an email sent to pharmacy faculty.
The pharmacy school is on South Columbia Street, a short walk from the armory.
11:09 a.m.: To clarify, Jim Gregory referred to the second incident involving a homeowner and an air rifle directly as a false alarm.
Gregory did confirm that no armed and dangerous person was found this morning during the campus lockdown and that there was no threat to campus, but he did not directly call it a false alarm.
