A boy was pinned down on his stomach after turning violent.
Three employees at Guiding Hands School Inc, in El Dorado, California, are being charged with involuntary murder of an autistic 13-year-old student.
The case dates back to November 2018.
Cindy Keller, the executive director, Staranne Meyers, the principal, and Kimberly Wohlwend, the special education teacher, pinned down Max Benson after the boy turned violent.
The student maintained in the same position for 2 hours until he became unconscious.
Max was transported to the hospital but died two days later.
According to the investigation, officials detained the boy “longer than necessary” and used more force than a “reasonable” amount.
A week later, the California Department of Education suspended the school certificate, which led to closing the school in last January.
Defendants can face up to four years in prison.
