A captain at California’s San Quentin State Prison was arrested last week in connection with an investigation into the sexual assault of an unconscious person, authorities said.

Orlando Ponce, 43, was arrested Thursday and charged with one count of forcible penetration of an unconscious person, according to a Press release from the Marin County Sheriff’s Office. Detectives were able to find probable cause for the arrest after the victim came forward on Jan. 30, the sheriff’s office said.

The alleged assault occurred in San Quentin Village, which is adjacent to the prison, the sheriff’s spokesman Sgt. said. Brenton Schneider said in an email on Tuesday.

Ponce’s court records in the Marin County Superior Court public index were not immediately available online. He was jailed on $100,000 bail but is no longer in custody, according to inmate records.

A phone number for Ponce was disconnected and an attempt to reach him via email on Monday failed. It is not clear if he has retained a lawyer.

The California Department of Corrections and Rehabilitation said Ponce has been with its office since 2001, when he was a cadet at the Richard A. McGee Correctional Training Center. He was promoted to captain on July 1, 2021, following a six-month stint on a limited captain’s assignment earlier that year.

His prison status was unclear Tuesday.
