Seventeen-year-old Derek Shrout appeared in court Monday on a charge of attempted assault.
Russell County Sheriff Heath Taylor says the teen was arrested after a teacher found a journal that appeared to describe the plot. He says the teen told investigators that he was a white supremacist and most of the alleged targets he named were black.
Shrout, who is thin and wears glasses, did not speak during the hearing. His attorney and family said they planned to post bond by the end of the day.
The judge ordered Shrout not to contact anyone at the school or use the Internet without supervision.
