Written message on Twin Valley South wall prompts evacuation of school

Students were evacuated from the building and deputies with the Preble County Sheriff’s Office, Montgomery County Sheriff’s Office and the Dayton Airport Police Department assisted with clearing the building, Simpson said.

The sheriff’s office did not locate anything inside the building and students were released.

High school students were dismissed at normal time and middle school and elementary students were released a little earlier than normal, Simpson said.

The sheriff’s office is working to determine who may have been responsible for the message.
