A 15-year-old student in Stafford County was arrested after a rifle, stolen from a deputy's cruiser, was found at his home amid an investigation into a reported threat against a fellow student. The investigation began after police were informed of the threat, leading to the identification of the suspect through social media. In a separate incident in Lake City, South Carolina, two juveniles were arrested for making threats against Lake City High School on social media. The first juvenile was arrested overnight Monday, followed by a second juvenile on Wednesday. Both are now in custody at the South Carolina Department of Juvenile Justice and will face charges related to the threats, which prompted the school district to switch to virtual learning. Authorities are continuing their investigations in both cases.
