US: Lingering disruptions likely in vicinity of Mount Horeb Middle School in Mount Horeb, Wis., after active shooter threat neutralized May 1 /update 1

Lingering disruptions to educational activities, transport, and business operations will likely affect the vicinity of Mount Horeb Middle School in Mount Horeb, Wisconsin, after authorities confirmed that an active shooter threat had been neutralized outside of the facility May 1. Officials did not immediately report any casualties in connection with the incident aside from the alleged shooter. Mount Horeb Area School District authorities asserted that the suspect did not breach the school building's entryway and students and staff are safe.

School district authorities placed the district on "full lockdown" amid the incident and have since begun to evacuate some students to reunify them with their family members. The dismissal of all school buildings is reportedly contingent on police approval. School district officials will likely provide further updates over the coming hours.

Police will almost certainly maintain a heightened security presence in the vicinity of Mount Horeb Middle School until any remaining investigative work is complete and all students are dismissed from school district buildings.
