MOUNT HOREB, Wis. (AP) — Wisconsin authorities on Thursday promised a thorough investigation of the fatal police shooting of a student who they say was armed outside a middle school, as families in the community gathered to comfort one another.

Authorities did not release additional details on the inquiry being led by the Wisconsin Department of Justice and have not released the name of the student.

“When faced with a deadly threat, they responded with deadly force,” Mount Horeb Police Chief Doug Vierck wrote in a Facebook post asking for patience with the ongoing investigation. “No officers, students, or staff were injured other than the armed individual.”
