SACRAMENTO, Calif. (AP) — A private school in El Dorado Hills and three of its staffers have been charged for involuntary manslaughter in the 2018 death of a 13-year-old autistic student, who died after being restrained for almost two hours for allegedly spitting at a classmate.

A recently convened special criminal grand jury indicted Guiding Hands, a now-closed school for students with special needs, its former principal Starrane Meyers, teacher Kimberly Wohlwend and site administrator Cindy Keller, the Sacramento Bee reported Thursday.

Each was indicted on a charge of involuntary manslaughter, El Dorado County District Attorney Office spokeswoman Savannah Broddrick said.

The indictments, which remain sealed, come almost three years after county prosecutors filed manslaughter charges against the defendants in November 2019. The three educators each entered a not guilty plea at an initial arraignment that month, and then the case dragged on in court as the two sides discussed a plea deal and the defendants changed attorneys, according to the Bee and prosecutors.

“If a case isn’t moving, we can do a criminal grand jury to move it along,” said Broddrick.

Wohlwend is accused of holding 13-year-old Max Benson in a restraint position for more than one hour and 45-minutes, as other staffers allegedly helped carry out a “take down maneuver” and held down his legs, according to a separate civil lawsuit filed by the boy’s family.

Attorneys for the school and staff did not immediately return calls seeking comment.

Max was restrained for allegedly spitting at a classmate. According to court documents, he was unconscious when an ambulance arrived, after having vomited and urinated on himself while being held face-down on the floor. He died a day later at UC Davis Medical Center.

The family’s civil suit said that Max lost consciousness 25 minutes before paramedics arrived. The lawsuit alleges that school staff took no action to check on Max’s medical condition or ensure that he was released from the hold.

In statements a few months after the child’s death, attorneys for the school said the de-escalation techniques were sometimes necessary to ensure the safety of students, staff and teachers.

In 2018, the California Department of Education wrote that school staff used “an amount of force which is not reasonable and necessary under the circumstances” while holding him down for 105 minutes.

Guiding Hands closed after the deadly incident and was replaced in 2019 by a different special education school, Point Quest Education.
