Antioch Inmate Lookup

Antioch inmate population records fall under the Contra Costa County Sheriff's Office. The city is in eastern Contra Costa County, one of the fastest growing areas in the region. Antioch does not have its own jail. People arrested by Antioch police go to the county detention facility for booking and holding. The county sheriff manages all jail operations for Antioch and the rest of Contra Costa County. To look up someone who was arrested in Antioch, you search the county sheriff's inmate database. This page explains the tools you can use and what records are available for Antioch inmates.

Contra Costa County Jail Search

The Contra Costa County Sheriff runs all jail facilities that serve Antioch. The main county jail is the Martinez Detention Facility, located in the city of Martinez. There is also a West County Detention Facility in Richmond. When Antioch police make an arrest, the person is transported to one of these county facilities. Booking happens at the county level. The sheriff's staff takes fingerprints, photos, and processes all paperwork. From that point on, the person is in county custody regardless of which city's police made the arrest.

Search for Antioch inmates through the Contra Costa County Sheriff inmate information page. This tool shows current inmates in the county system. Enter a name and the results will show charges, bail amount, booking date, and facility location. The system covers all people booked into Contra Costa County jails, including those arrested in Antioch. Updates happen throughout the day. A new booking from Antioch may take a few hours to show up online after the arrest occurs.

Contra Costa County's jail capacity has been a topic of debate for years. The facilities sometimes run near capacity. The county uses alternatives like electronic monitoring and supervised release to manage the inmate population. This can affect how long someone arrested in Antioch stays in the jail before release or transfer.

Antioch Police Department

The Antioch Police Department handles law enforcement for the city. It is a busy department. Antioch has grown fast over the past two decades, and the police force has worked to keep up with that growth. Officers make arrests within city limits and process them before handing off to the county. The Antioch PD does not run a public inmate search tool. All custody information goes through the Contra Costa County Sheriff's system once an arrest is booked.

You can reach the Antioch Police Department at (925) 778-2441 for questions about recent arrests. The main station is at 300 L Street in Antioch. For non-emergency records requests, the department's records division can help. They handle copies of arrest reports and incident logs. Booking records themselves are kept by the county sheriff since that is where inmates are held. Under Government Code 6254(f), basic arrest information is public. You can get the person's name, charges filed, and booking details through either the police department or the county.

Note: Antioch PD has been under a federal civil rights investigation in recent years. This has led to changes in department policy, but the booking and custody process for inmates still works the same way through the county sheriff.

California Statewide Search Tools

For people from Antioch who went to state prison, use the California CIRIS inmate locator. CDCR runs this free search tool at ciris.mt.cdcr.ca.gov. It covers all 34 state prisons. Search by name or CDCR number to find someone serving a state sentence. CIRIS shows the person's current prison, admission date, and parole details.

Accessing Antioch Inmate Data

Booking information for Antioch arrests is public record. California law allows anyone to see the name, charges, bail, and booking date for any person in county custody. The Contra Costa County Sheriff makes this available through its online search. You do not need to show ID or explain why you want the data. Full criminal histories are restricted under Penal Code 11105. Only certain agencies and the person themselves can access a complete criminal record in California.

If you need records beyond basic booking data, you can file a public records request with the Contra Costa County Sheriff. The California Public Records Act requires a response within 10 days. The sheriff must provide records that are not exempt from disclosure. Arrest reports, booking logs, and daily jail population counts are generally available. Medical records, ongoing investigation files, and some personal data are exempt. For Antioch-specific arrest reports, you may also contact the Antioch Police Department records division directly.
