MISSOULA, Mont. (AP) - A Montana high school has been placed in lockdown after a loaded, handgun ammunition clip was found in a school hallway.
Police and officials at the Sentinel High School in Missoula were investigating Monday where the clip came from and whether a firearm was in the school.
Missoula Police Sgt. Travis Welsh says no firearm was immediately found.
Welsh says a construction worker found the ammunition clip Monday morning and turned it in to school officials, who immediately imposed the lockdown, which prevents anyone from entering or leaving the school and keeps students in their classrooms.
