Robert Presley Detention Center Inmate Search is the primary method for locating individuals currently held at this Riverside County facility. The jail sits at 4000 Orange Street in downtown Riverside, California, and serves as one of the county’s main detention centers. Opened in 1989, it replaced the older Riverside County Jail and now houses up to 800 inmates across various security levels. The center operates under the Riverside County Sheriff’s Office, with Captain Michael L. Hayes leading daily operations as of 2024. Staff includes around 250 correctional officers, medical personnel, and support workers who manage safety, healthcare, and inmate programs. Families, legal representatives, and law enforcement use official channels to find inmate status, send mail, schedule visits, or get booking details.

How to Perform a Robert Presley Detention Center Inmate Search
Anyone can search for an inmate at the Robert Presley Detention Center using the Riverside County Sheriff’s Office public database. The system allows queries by full name, Social Security Number (SSN), State Prison Number (SPN), or date of birth. Results show the inmate’s booking photo, current charges, bail amount, and estimated release date. The database updates every 24 hours, so information is current but not real-time. For accuracy, always double-check spelling and use legal names only. Nicknames or aliases won’t return results. This service is free and available online 24/7 through the Sheriff’s official portal.
The search tool is designed for both families and professionals. Law enforcement agencies use it to verify custody status, while relatives check on loved ones. If no results appear, the person may be held at another facility, recently booked, or released. In such cases, calling the jail directly at (951) 955-4400 provides faster confirmation. Always have the inmate’s full legal name and booking number ready when calling.

Official Inmate Search Tools and Databases
The most reliable way to find an inmate is through the Riverside County Sheriff’s Inmate Information System. This online portal, hosted at jimspub.riversidesheriff.org, lets users search by name or booking date. Searching by date shows all individuals processed that day, while name searches return detailed profiles. Each profile includes the booking number, arresting agency, charge description, and a thumbnail of the booking photo. Users can filter results by facility to focus only on the Robert Presley Detention Center.
Another option is the county’s general public record portal, which consolidates data from all Riverside County jails. It supports searches using SSN, SPN, name, or DOB. Results display mugshots, charges, bail, and release dates. Both systems are updated daily and are the only officially endorsed sources. Avoid third-party sites that charge fees—these often repackage public data and may be outdated or inaccurate.

Frequently Asked Questions About Robert Presley Detention Center Inmate Search
Many people have questions about how to find an inmate, send mail, or visit. Below are the most common inquiries with clear, direct answers based on official policies and procedures. These responses reflect the latest information from the Riverside County Sheriff’s Office as of 2024.
How often is the inmate database updated?
The Riverside County inmate database refreshes every 24 hours. This means new bookings, releases, and status changes appear within one day. However, real-time updates are not available. If you don’t see an inmate listed, they may have been booked very recently, transferred, or released. For immediate confirmation, call (951) 955-4400. Always use the inmate’s full legal name and booking number when calling. The system does not support searches by nickname or alias. Updates occur overnight, so morning checks yield the most current data.
Can I visit without being on the approved list?
No. All visitors must be pre-approved by the inmate through the jail’s online portal. The inmate adds your name, and you receive confirmation before scheduling. Walk-in visits are not allowed. Each visitor needs a valid government-issued ID. Minors must show a birth certificate and be accompanied by a parent or guardian. Up to five people may visit per session. Failure to follow this rule results in denied entry. Schedule visits by calling (951) 341-8888 after approval.
What happens if my mail is rejected?
Mail is rejected if it lacks the sender’s name, return address, inmate’s full legal name, or correct booking number. Packages over 12 × 12 inches are also returned. Prohibited items include cash, stamps, homemade food, or contraband. Rejected mail is sent back to the return address. If no address is provided, it is discarded. To avoid issues, double-check all details before mailing. Use only plain envelopes and standard paper. All correspondence is logged and inspected.
Are mugshots public record?
Yes. Booking photos are part of the public record and appear in the online inmate search results. They are updated weekly and linked to the inmate’s profile. Third-party sites may republish these images, but only the Sheriff’s Office provides official, current data. Mugshots remain online until release or transfer. Expungement does not automatically remove them. For privacy concerns, contact the Sheriff’s Office directly.
How do I check if someone was released?
Search the inmate database using their name, SSN, SPN, or DOB. If no results appear, they may have been released. Call (951) 955-4400 for confirmation. Released inmates are removed from the roster within 24 hours. Note that release dates are estimates and can change due to court decisions or holds. Always verify with official sources, not third-party websites.
Can I send money to an inmate?
Yes, but not through mail. Use JPay or Access Secure Pay to deposit funds electronically. These services link to the inmate’s account for commissary purchases. Cash, checks, or money orders sent by mail are not accepted and will be returned. Deposits are processed within 24–48 hours. Have the inmate’s full name and booking number ready when sending money.
What if the inmate is not at Robert Presley Detention Center?
The person may be held at another Riverside County facility, such as the Larry D. Smith Correctional Facility or Riverside County Jail. Use the county-wide search tool to check all locations. If still not found, they could be in state prison, federal custody, or recently released. Contact the Sheriff’s Office at (951) 955-4400 for assistance.
