Carter County Sheriff’s Office arrest Happy Valley High student for threat

The Carter County Sheriff’s Office arrested a Happy Valley High School student following a social media threat to the school. The sheriff’s office learned of an online threat of violence involving firearms at Happy Valley High School on September 11. After an investigation, a 15-year-old Happy Valley High School student was charged with threat of mass violence on school property. This incident is unrelated to a threat and subsequent false reporting charge to an Elizabethton High School student Friday, who reportedly admitted to posting a different threat against Happy Valley High School.
