Police say a north Alabama high school student wrote out plans for a mass killing and tried to get others to provide weapons for the plot, which included burning a teacher alive.

Police in Ardmore acted on a tip to foil the plan. They met Monday with school officials to determine what to do next.

Authorities say a 16-year-old boy who attended Ardmore High School wrote notes and drew pictures about a mass killing. He allegedly compiled a list of students and teachers to kill.

The mother of another student alerted police after the youth allegedly tried to obtain weapons from her child.

Ardmore police arrested the 16-year-old on Friday, seizing five swords and a computer at his home. He was placed in juvenile detention.
