UPDATE 8:30 P.M. Kewaunee School District cancels classes for Friday. The letter that was sent to parents and posted online is below.

The Kewaunee School District facilities remain locked down after a threat was made Thursday morning. Kewaunee School District Superintendent Karen Treml said the high school office received the threatening phone call before 9:30 a.m. The phone call did not name a specific school in the threat, but the unidentified caller did mention the possible use of a weapon. The district immediately called local law enforcement and the district’s facilities went into lockdown at 10:30 a.m. Students stayed primarily in their classrooms until they were released between 12:45 p.m. and 1:15 p.m. Once the building is completely vacated, Kewaunee Police Chief James Kleiman said the department will do a complete search of the facilities to determine if there are any other details that can be used for their investigation. Treml said they are working with local law enforcement to discuss a plan moving forward, including if classes will be held on Friday.

Kewaunee County Sheriff Matt Joski said he is proud of how the Kewaunee Police Department and the Kewaunee School District responded to the incident.

All area schools in Kewaunee County were notified of the incident, causing Algoma and Luxemburg-Casco School Districts to go into a soft-lockdown as well. Kleiman said more information will be released as soon as it is available.
