Find Jail Roster in Benton County
The Benton County jail roster is the public list of people booked into the county jail by the Benton County Sheriff. Use it to look up an inmate by name, find a booking date, or check the charges filed. Benton County sits in south-central Washington, and the jail serves the Tri-Cities area on the west bank of the Columbia River. This page walks you through how to search the Benton County jail roster, where to find related court data, and what to do when the local list is thin.
Benton County Jail Roster Overview
Benton County Sheriff and Jail Roster
The Benton County Sheriff's Office runs the county jail and keeps the Benton County jail roster. The jail holds pre-trial detainees and sentenced inmates. The Sheriff's Office serves the unincorporated parts of the county and runs the jail for the full county. Arrests from Kennewick, Richland, Prosser, and West Richland all feed into the same jail, so most city cases end up on the same Benton County jail roster.
The jail roster lists the inmate name, booking date, charges filed at booking, and the bail amount when set. Some pages show a booking photo. The roster is updated as new bookings come in, but a new arrest can take a few hours to post.
If the person you want is not on the Benton County jail roster, call the Sheriff's records desk. They can check the live system or tell you when the person was moved to a state prison under RCW 72.09.
Note: Benton County is a two-seat county with offices in both Prosser and Kennewick, and the jail roster covers the full county.
How to Search the Benton County Jail Roster
Start with the name of the person you want to find. Type the last name into the Sheriff's roster lookup. The list will show the booking date, the hour of the hold, the cause of the hold, and the bail or bond amount. Scan the list for the right match. Open the booking page to see the full set of data.
If the name is not on the Benton County jail roster, try the state tools. The Washington DOC Incarcerated Search is for people held in state prison after a long sentence. The Odyssey court portal lets you tie a jail roster name to a case in Benton County Superior Court or Benton County District Court. Both are useful when you have a name and need the next hearing date.
To run a quick name search on the Benton County jail roster, you will need:
- The full name of the person
- The date of arrest if you know it
- The city or part of the county
Call the Sheriff's records desk when the online roster is down or when a new booking is slow to post.
Public Records and the Benton County Jail Roster
Under RCW 70.48.100, every jail in Washington must keep a register open to the public. The Benton County jail follows this rule. The jail register lists the name of each person held, the hour and date of the booking, the cause of the hold, and the hour, date, and manner of release. This is the core of the Benton County jail roster.
Medical records, mental health records, and security plans are exempt from disclosure. The full inmate file is held in confidence and only shared with criminal justice agencies, the courts, or with the written consent of the person. The Benton County Public Records Portal is the formal way to ask for records beyond the basic roster.
The Public Records Act at RCW 42.56 gives you a strong right to ask for records. You do not need to give a reason. The county must reply within five business days. The reply may be the record, a denial, or a time estimate. News use is fine. A list of names for pure commercial use is not allowed.
Note: Benton County must reply to any records request for the Benton County jail roster or related files within five business days.
Custody Alerts for Benton County
The state runs a free alert service called VINE. Sign up with a name and a phone or email. The system will send an alert when a Benton County inmate is released, moved, or booked again. VINE is free and kept in confidence. It works for both the Benton County jail and the state prison system.
The Washington Association of Sheriffs and Police Chiefs helps coordinate jail standards and notification data across the state. VINE is the best fit when you want a live alert but cannot check the Benton County jail roster each day. The DOC Victim Services Program at (800) 322-2201 helps when the person has been moved from the jail roster to a state facility.
Courts Tied to the Benton County Jail Roster
The Benton County jail roster does not show the full court file. Benton County Superior Court handles felony cases. Benton County District Court handles most misdemeanor cases. Both feed into the Odyssey court portal. Use the portal to tie a jail roster name to a case number and a next hearing.
For a formal criminal history, use the WATCH service from the State Patrol. WATCH is a paid conviction history check. It is not a live roster. It only shows cases that led to a conviction.
For federal holds, the Federal Bureau of Prisons Inmate Locator lists federal inmates. The ICE Online Detainee Locator covers people held on immigration matters.
