Near the end of the school day yesterday, Avery County High School was put under a "preventative lockdown" for about 30 minutes after a suspicious person was spotted in the school. Superintendant David Burleson said a young lady at the high school reported seeing a person she did not know walk into the high school, that report leading to the lockdown, starting about 2 p.m. during the schools fourth period. After a law enforcement and staff check of the building, nothing was found out of order, and the lockdown was lifted, with students released from school at the regular time. Burleson said that the schools would always put safety first , and said he called an after school meeting of school principals and staff to process what took place, still trying to identify the man, making sure the unidentified person was not a staff member or someone else identifiable. He said it was also a chance to give a review of school safety measures, saying We don't want to take any chances, we want to make sure we don't leave any stone unturned." Burleson said the young lady who saw the man told a teacher, who then alerted school officials that an unidentified person could be somewhere in the building.
