Superior Middle School went into a “lock hold” safety protocol at 9:40 a.m. Tuesday, May 7 to allow building staff to address a safety concern within the building. The hold lasted about 20 minutes, according to District Administrator Amy Starzecki. The concern was addressed, the hold lifted and the school day proceeded as normal.

"There was minor disruption to regular school activities and minimal risk to the safety of the school," Starzecki said in an emailed statement.

Parents were notified via email and social media after the lock hold was lifted. One parent reported receiving the email from SMS Principal Rick Flaherty at 10:55 a.m. The information was posted on Facebook about a half-hour later.

Everyone was safe and students and staff were able to continue with classroom activities during the hold, according to Flaherty's email.

"We are proud of our Superior Middle School administrators, teachers, staff and students who did a great job following the safety procedures we practice on a regular basis in our district," Starzecki said.

The district didn’t release any additional information about the incident to protect student privacy.

Patrol officers with the Superior Police Department were not aware of the lock hold at SMS, and there were no calls on the dispatch log for any activity like that at the school, according to Assistant Chief Matt Markon.
