Police shot and killed a Wisconsin student outside a middle school after receiving a report of someone with a weapon, the state’s attorney general said in the first law enforcement briefing on an incident that sent children fleeing amid gunfire.

Authorities in Mount Horeb had previously said an active shooter who never got inside was “neutralized” outside the district’s middle school building Wednesday.

Attorney General Josh Kaul said at the news briefing that no one inside the school was injured in the incident earlier Wednesday. He said the state Department of Justice is handling the ongoing investigation into the shooting.
