The teen boy accused of stabbing a fellow Montgomery High School student to death in March was followed to his art class by a group of students before the stabbing. Footage of the 15-year-old boy being followed to class was shown in court on Wednesday. Four boys were following the freshman, including the 16-year-old boy who was stabbed to death during a fight in the classroom. The four boys who followed the stabbing suspect were not students in that class. The voluntary manslaughter trial is expected to last through next week.
