An official notice posted to the school district Facebook page reported someone had made a social media post stating a shooting would take place at the Plattsmouth Middle School.
An investigation by law enforcement determine the threat was credible. Contact has been made with one, but not all, possible suspects. The district notice said such threats are taken seriously and officials decided not to hold classes to insure the safety of students and staff.
The Cass County Sheriff’s Office is investigating the matter.
