How to Find an Inmate at Marsh Creek Detention Facility

Members of the public can look for someone in custody by using the official inmate search link available on this page for the facility’s roster. County inmate rosters typically list the person’s name, booking date, listed charges, housing or custody status, and possible release or court information when available. Records do not always appear right away after an arrest or transfer. Booking, classification, and data entry can take several hours, so a newly booked person may not be searchable immediately. If the person does not appear, check again later or contact the Contra Costa County Sheriff’s Office for custody information.
