John Alfred Klang, 49, was killed at Weston High School in Cazenovia, Wisconsin, on September 29, 2006. Klang was the school’s principal and district administrator. A 15-year-old student, Eric Hainstock, entered the school armed with a shotgun and a handgun. A custodian wrestled the shotgun away after Hainstock aimed it at a social studies teacher, but Hainstock still had a handgun concealed in his jacket.

Principal Klang confronted Hainstock in a hallway and struggled with him. During that struggle Hainstock fired the handgun multiple times, wounding Klang. Despite his injuries, Klang managed to disarm Hainstock and throw the gun away. Klang was taken to the University of Wisconsin Hospital in Madison and died later that day. Hainstock was arrested at the scene and charged with first-degree intentional homicide.

Klang was remembered for his dedication and for preventing further harm. Does anyone who knew John Klang or was at Weston High School that day have additional details about his actions or the response inside the building?
