The mother of a five-year-old student with autism wants to know how her son was able to leave his school without anybody noticing. Blake Greenley was missing from Bruce Elementary for about an hour before a concerned driver picked him up from a busy roadway. Karen Stacy posted the boy’s picture on Facebook and his mother, Crystal Borzick, was notified by a friend. Stacy says he was cold and crying when she found him. When Borzick called the school, nobody knew her son was missing.
