In September 2018, a 17-year-old student was changing clothes in a dressing area inside a fashion design classroom when she noticed a box on a shelf with a light coming from it, investigators said. She found a cellphone recording a video inside the box and told the school’s principal, who contacted the sheriff’s office.

Ackett reportedly admitted to deputies that he had been recording students without their knowledge since January 2017.
