Mehlville High locked down after threat Monday, three other district schools ‘locked out’

Editor’s note: As of  2:54 p.m. Monday, the lockouts at Hagemann, Trautwein and Washington have been lifted. Washington is dismissing school for the day as normal. 

Three Mehlville School District schools are on “lockout” due to police activity in the area, according to an email from the district.

Trautwein Elementary, Hagemann Elementary and Washington Middle are on lockout as of 2:31 p.m. Monday. A lockout is used when there is police activity near a campus. Students outside for class or recess return to the building and all exterior doors are locked. Nobody is allowed to exit the building and instruction continues. Depending on the situation, teachers may move students to different areas of their respective buildings.

Earlier Monday morning, Mehlville High School was put under lockdown after a threat to “invade the school during the 12:32 p.m. passing period,” the school district said. Students were locked in their classrooms and no one could enter or exit the school.

The lockdown at MHS was lifted at 1:35 p.m. after police and school administration determined the source of the threatening message, which was air dropped to students and staff. School dismissed as normal at 2:10 p.m.
