Police shot and killed a student outside a Wisconsin middle school Wednesday after receiving a report of someone with a weapon, the state's attorney general said in the first law enforcement briefing on gunshots that sent children fleeing and prompted an hourslong lockdown of local schools. Authorities had previously said an active shooter who never got inside the building was “neutralized” outside Mount Horeb Middle School. State Attorney General Josh Kaul told reporters Wednesday evening no one else was harmed and that an investigation is ongoing.
