Riverside Inmate Locator: Finding Detainees At Cois M. Byrd (CMWB) And County Jails (2026)
Locating a recently arrested individual in Riverside County requires navigating the Riverside County Sheriff’s Office (RCSO) corrections database. Searches for "Riverside CMWB" typically reference detainees processed through the Cois M. Byrd Detention Center (frequently abbreviated in public records searches as CMBDC or colloquially queried as CMWB) in Murrieta, or the broader Riverside County Jail Web-based booking portal.
Understanding how the county processes, houses, and displays public inmate records is essential for locating an individual quickly, posting bail, scheduling visits, or arranging legal counsel. This operational guide details how to navigate the 2026 Riverside County inmate locator system, interpret custody status records, and interface with the region's correctional facilities.
Riverside County Custody Intake and the Online Locator System
The Riverside County Sheriff’s Office manages corrections across five primary facilities. When an individual is arrested by the RCSO, local municipal police departments (such as Riverside PD, Murrieta PD, or Temecula PD), or the California Highway Patrol within county lines, they are brought to a regional intake facility for booking.
Booking involves fingerprinting via Live Scan, digital mugshot capture, warrant checks, medical screening, and registration into the county's central database. Public records are updated automatically once an inmate completes initial intake, which typically takes between two and six hours depending on facility volume, medical triage priority, and identity verification.
Operational Custody Notice
Online arrest records reflect active custody status within Riverside County facilities only. If an individual has been transferred to the California Department of Corrections and Rehabilitation (CDCR), released on their own recognizance, or transferred to federal custody, their record will transition from active custody to released status within twenty-four hours.
How to Conduct an Inmate Search in Riverside County
To find an inmate housed at Cois M. Byrd or any affiliated Riverside facility, researchers and families must access the public inmate information portal operated by the Sheriff's Corrections Division. Follow these sequential steps to retrieve accurate custody data:
- Gather Accurate Identifying Information: Collect the detainee's legal first name, middle name, and last name. Having their exact date of birth substantially narrows results, preventing confusion with individuals sharing identical names.
- Access the Corrections Database: Navigate to the official Riverside County Sheriff's Department Inmate Information System.
- Input Search Query Parameters: Enter the subject's booking number if known. If unavailable, enter the full legal last name followed by the first initial or full first name.
- Filter Active vs. Released Detainees: The locator defaults to current, housed inmates. If the arrest occurred more than forty-eight hours prior and yields no results, expand the search parameters to include recent releases.
- Verify Custody and Housing Location: Examine the search results to confirm the individual's full name, race, age, and designated facility location (e.g., Cois M. Byrd Detention Center, Robert Presley Detention Center).
- Note Mandatory Identifiers: Document the inmate's permanent Booking Number, Court Case Number, Next Appearance Date, Assigned Facility, and Total Bail Amount.

Interpreting Inmate Records and Case Status
Search results on the Riverside County portal supply legal identifiers critical for court monitoring and legal defense preparation. Understanding these entries prevents misinterpretation:
- Booking Number: A unique ten-digit identifier generated at intake. This number remains attached to the specific arrest event and is required for funding commissary accounts, scheduling video visitation, and executing bail bonds.
- Arrest Agency: Identifies the arresting law enforcement department, such as Riverside Sheriff Southwest Station, Corona Police, or California Highway Patrol.
- Charges and Penal Code References: Violations appear alongside California Penal Code (PC), Vehicle Code (VC), or Health and Safety Code (HS) designations. Felonies are distinguished from misdemeanors directly in the narrative charge description.
- Bail Amount: Displays the aggregate monetary surety required for pre-trial release. Multiple charges will list individual scheduled bail amounts, totaled at the bottom of the entry. If listed as "NO BAIL," the individual is held on a capital charge, an active parole revocation, a probation hold (Penal Code 1203.2), or a judicial bench warrant.
- Court Information: Displays the assigned municipal courthouse (e.g., Southwest Justice Center, Riverside Hall of Justice, Banning Justice Center), the division or courtroom number, and the scheduled arraignment date and time.
Bail, Bond Posting, and Release Protocols
Once an inmate is cataloged in the system with a set bail amount, release procedures can commence. Riverside County operates under the California Uniform Bail Schedule, with local baseline determinations set annually by the Riverside County Superior Court judges.
Cash Bail and Court Bonds
Families may post the entire bail amount directly at the designated detention facility's cashier window, accessible twenty-four hours a day. Cash, cashier's checks drawn from certified banking institutions, and money orders made payable to the Riverside County Superior Court are acceptable. Personal checks are categorically rejected. Cash bail is held by the court until the legal case concludes and is returned minus administrative court fees, provided the defendant attends every scheduled appearance.
Surety Bonds via Licensed Bail Agencies
When paying the complete bail sum is unfeasible, families commonly contact licensed California bail bond companies. The standard premium charged by a bail surety under California Insurance regulations generally ranges between seven and ten percent of the total bail amount. This premium is non-refundable. Bail bond agents utilize the inmate's booking number and location to post a corporate surety bond directly with the facility intake desk.
Pre-Trial Services and Own Recognizance (OR) Release
Non-violent offenders, low-level misdemeanor arrestees, and qualified individuals may be evaluated for pre-trial release without monetary bail under local pre-trial assessment protocols. County pre-trial officers interview detainees to evaluate public safety risks, community ties, and flight probability before making recommendations to the presiding arraignment judge.
Communication, Visitation, and Inmate Accounts
Contacting an inmate at the Cois M. Byrd Detention Center or regional branch facilities requires strict adherence to institutional safety protocols.
Video and In-Person Visitation
All visits must be scheduled at least twenty-four hours in advance through the county's designated vendor portal or the on-site scheduling kiosks located in the lobby of the facility where the inmate resides.
- Visitors must produce a valid government-issued photographic identification (e.g., California Driver's License, United States Passport, Military Identification).
- Minors must be accompanied by an authorized parent or legal guardian.
- Visitors are subject to strict dress codes: no transparent attire, no gang-affiliated insignias, no excessively revealing garments, and no apparel mimicking inmate clothing colors (orange, hunter green, or yellow).
- Inmates classified under disciplinary isolation or protective administrative segregation may have restricted visitation privileges.
Phone Access and Digital Messaging
Detainees cannot receive incoming telephone calls. Upon intake and placement into permanent housing units, inmates receive access to collect calling and contracted prepaid phone platforms. Friends and family can establish prepaid communication accounts through the county’s authorized telecommunications contractor. All calls, excluding verified attorney-client conversations, are subject to real-time monitoring and recording.
Inmate Trust and Commissary Accounts
Funds can be deposited into an inmate's trust account to permit purchasing personal hygiene items, approved packaged snacks, correspondence stationary, and over-the-counter medical sundries. Deposits are handled via:
- Lobby Kiosks: Located within the public entrance areas of Cois M. Byrd, Robert Presley, and John J. Benoit facilities, accepting cash, credit cards, and debit cards.
- Online Vendor Portals: Secure processing systems that post funds within twenty-four hours using the inmate's full name and booking identifier.
Frequently Asked Questions
Where is an inmate held if arrested in Murrieta or Temecula?
Arrestees from Southwest Riverside County, including Murrieta, Temecula, Menifee, and Lake Elsinore, are generally transported and processed at the Cois M. Byrd Detention Center located at 30755-B Auld Road in Murrieta.
The facility sits directly adjacent to the Southwest Justice Center, where most initial arraignments for the southwest region take place. If housing limits are reached or an inmate requires high-acuity medical care, the individual may be transferred to the Robert Presley Detention Center in downtown Riverside.
How often does the Riverside County online inmate locator update?
The Riverside County Sheriff's Office online database updates regularly, typically refreshing intake, housing, and release statuses every one to two hours.
However, during peak booking windows—such as weekend overnights or following multi-agency enforcement operations—the processing timeline between physical booking and public database appearance can extend to four to six hours while identification verification and medical classifications are finalized.
What should I do if an inmate's status says "No Bail"?
A "No Bail" status indicates the inmate cannot be released through monetary surety until appearing before a judge for formal arraignment.
This classification typically occurs when an individual is charged with specific violent felonies, has an outstanding fugitive warrant from another county or state, or holds an active violation hold from state parole or county formal probation. An attorney can petition the court for a bail review hearing during the initial arraignment.
Can I look up an individual's past criminal history on the inmate locator?
No, the Riverside County Inmate Information System only details active, current incarcerations and very recent custody releases.
To review past criminal convictions, historical case documents, or closed court files, researchers must access the Riverside County Superior Court's public records portal (Public Access System) or request records directly from the Court Clerk’s Office in the relevant judicial district.
How do I locate property taken during an arrest at Cois M. Byrd?
Inmate personal property collected at the time of arrest is secured at the facility where the individual is actively housed.
Detainees can authorize the release of their personal property—excluding clothing, money, and items cataloged as criminal evidence—to a designated third party by completing an internal Property Release Authorization form within the jail facility. The designated recipient must present valid state identification at the facility's lobby window.
Securing Legal Support and Next Steps
Once custody status and housing locations are confirmed via the Riverside inmate locator, securing qualified criminal defense counsel represents the most critical subsequent action. Arraignments in Riverside County must take place within forty-eight hours of arrest, excluding weekends and official court holidays. Retaining legal counsel before the initial court appearance gives the defense attorney immediate opportunities to contact the assigned deputy district attorney, contest unreasonable bail schedules, examine probable cause declarations, and seek immediate pre-trial release.
