A social media threat directed toward Terry Sanford High School in Fayetteville is under investigation, school officials said. Terry Sanford High School Principal Thomas Hatch informed parents and students of the threat in an automated message sent Sunday. School officials are cooperating with law enforcement officials, Cumberland County Schools spokesman Lindsay Whitley said Sunday night. Whitley said depending on the investigation, Terry Sanford High School could operate under a “code yellow,” status Monday morning, meaning there would be additional investigation and security at the school. Cumberland County Sheriff’s Office is handling the investigation, he said.
