Onalaska Middle School closed Tuesday due to “serious threat”

Another potential threat to a local school.

A letter from the Onalaska School District sent late Monday to parents said classes and school activities Tuesday would be cancelled due to a “serious threat”.

The message from executive assistant Kristen Fay says the district and the Onalaska police department were made aware of the threat toward the middle school and that police are investigating its “validity.”

Because of the timing, the district cancelled everything Tuesday to give police and school administrators time to thoroughly go through everything.

She added that more detailed information will be shared with district families and staff when its received.

All the other facilities with the Onalaska School District will run as normal Tuesday.

This is the sixth such school threat in the area in the past month in a half — though at least two of them were not credible.

In late October, Winona Police investigated a Snapchat threat that mentioned “Central High School” but was deemed a hoax — a screenshot mentioning a “generic” school that was shared all over the place.

In late November, Holmen Middle School had to deal with a school threat and referred a minor to the juvenile court system for charges of “Terroristic Threats and DC with a Computerized Device.”

Police have not released any other details into the incident.

A week before that, someone was “identified” by police for a Snapchat threatening to kill students and staff at Logan High School.

Before that, a threat toward Central High School led to the arrest of a 17 year old.
