MISSOULA, Mont. -- Sentinel High School went on lockdown Monday morning while students were in first period. The lockdown began at 8:25 a.m. and ended around 12:05 p.m. when officials began escorting students from the building.
The school will be open Tuesday with an increased police presence on campus and in the surrounding neighborhood.
School officials say the magazine was handed in by students, not construction workers, as police officials first told us.
We’re told the students gave officials a description of the person they suspect dropped the magazine, but that information is not being released.
Administrators say there was no active threat.
School and law enforcement officials dismissed students early to conduct a thorough search of the school after the magazine of ammunition was found.
“We have completed a comprehensive, room-by-room search of this building and all student lockers. We have no evidence that has led us to a suspect or to conclude that the students and staff at this high school are in danger,” said Sentinel Principal Ted Fuller.
Authorities say a handgun was not found in an initial search of Sentinel High School in Missoula on Monday.
Missoula Police Sgt. Travis Welsh initially said a construction worker found the ammunition magazine Monday morning and turned it in to school officials.
They immediately imposed a lockdown, which prevents anyone from entering or leaving the school and keeps students in their classrooms.
School officials said in an email to parents that dismissing students after noon would allow for a more comprehensive search and would be the safest solution for the school.
Police were guarding the perimeter of campus.
