Mario Solis

31 years old · died September 3, 2022 · Cois M. Byrd Detention Center, Riverside County, California

Mario Solis, 31, died on September 3, 2022, while held at the Cois M. Byrd Detention Center in French Valley, Riverside County, California. His family's lawsuit says he had a long history of suicidal behavior and that a nurse could not give him his psychiatric medication that night, and that deputies kept on their rounds for 11 minutes after finding him unresponsive. The Riverside County sheriff-coroner ruled the death accidental, citing asphyxia after he swallowed several objects, and the family's attorney strongly disputes that finding. In February 2026 a federal jury found that deputies and jail medical staff did not violate his constitutional rights, and his mother's attorney said she will appeal.
