(CNN) Jo Grayson said she was alarmed when her son, Thatcher, came home from his middle school covered in cuts and bruises. Earlier in the day, Thatcher's teacher texted Grayson to alert her to an incident involving him. The footage shows Thatcher, who is autistic and mostly nonverbal, being dragged down a school hallway by his teacher and the school nurse. "I just don't understand how someone can do this to a child, let alone to a person with disabilities," Grayson told CNN. Thatcher is a sixth-grader at Tates Creek Middle School in Lexington, Kentucky.
