A Woodstock High School student voluntarily agreed Friday to leave Cherokee County until his trial on charges that he brought an unloaded gun to school, disrupting classes and triggering fears of a Columbine-like attack. A magistrate set bond for Forrest Busby, 17, of Canton at about $36,000 late Friday afternoon. But Busby's attorney said she expects the teen will spend the weekend in jail while plans are made to have a monitoring device equipped to his ankle.
