RICHMOND, Va. — Irvo Otieno, a 28-year-old Black man whose death last month at a Virginia mental hospital has sparked outrage and led to second-degree murder charges against 10 defendants, died of "positional and mechanical asphyxia with restraints," a medical examiner's office said Monday.

Arkuie Williams, the administrative deputy in the state Office of the Chief Medical Examiner, confirmed the cause of death findings to The Associated Press after attorneys for Otieno's family first shared them in a statement. The manner of death was homicide, Williams wrote in an email.
