CARROLL COUNTY, Va. - Shortly before 10 a.m., the Surry County, North Carolina Sheriff's Office notified the Virginia State Police that a man they were searching for was traveling north on Interstate 77 into Virginia.
The suspect is under investigation for a threat of violence involving a school. The vague threat did not specify a name or location of any school, according to state police.

There is nothing to indicate the man left the interstate as he traveled through Southwest Virginia.
