KASSON, Minn. – The principal of the Kasson-Mantorville High School, Trent Langemo, asked for a greater police presence at the school after a potential threat. Police determined the threat was “non-credible,” but Langemo thought a police presence would be calming and send the right message. The school has 670 students. The school grapevine was abuzz about the threat by 2:15 p.m. when Langemp called police. He said the rumors had spread by technology and rumors.
