MISSOULA – Sentinel High School in Missoula was locked down after some gun ammunition was found on Monday morning.
School officials notified parents that the school was locked down and that nobody was allowed in or out of the building.
Missoula County Public Schools reports a loaded ammunition magazine fitting a handgun was found on the ground in a hallway.
The clip was turned into the office and an investigation to try and identify the source of ammunition and look for a possible weapon.
The main school doors were locked. Students were not to be dismissed until an “all clear” was issued by law enforcement.
Students were told of the lockdown by their teachers and remained in their first-period classrooms.
“The school is supported by multiple law enforcement staff at this time and the environment is being calmly maintained by staff,” MCPS said in a social post.
