Pennington County Inmate Search
Pennington County inmate population records are kept by the Sheriff's Office in Thief River Falls, which serves as the county seat in northwestern Minnesota. The county has a population of roughly 14,000 people spread across a largely agricultural area near the Red Lake River. The jail handles bookings for local arrests, and most of that custody data is public under Minnesota law. Whether you need to check on someone currently held at the county jail or look up older booking records, the Sheriff's Office is the place to start. State databases also cover inmates who have been moved to prison facilities after sentencing in Pennington County.
Pennington County Overview
Pennington County Sheriff's Office
The Pennington County Sheriff's Office manages the county jail and maintains inmate population records. The office handles patrol duties, civil process, court security, and detention for the entire county. Thief River Falls is the hub of county government, and the jail there processes all local bookings. Staff can tell you whether someone is in custody when you call with a name and date of birth.
Northwestern Minnesota has a different feel than the Twin Cities metro. Pennington County is rural and spread out, with small towns, farms, and stretches of open land. Law enforcement here covers a lot of ground with fewer resources than urban departments. The Sheriff's Office works with the Thief River Falls Police Department and other local agencies on joint operations. When any of those agencies make an arrest, the person typically ends up at the Pennington County jail for booking.
The jail has limited capacity. That is common for smaller counties in Minnesota. When the jail gets full, the county may board inmates at nearby facilities through agreements with other jurisdictions. This can affect where inmate population records are stored. If someone was arrested in Pennington County but boarded elsewhere, you may need to check both the local and the boarding facility to get complete records.

Finding Pennington County Inmates
Call the Sheriff's Office to check current custody status. Give the person's name and date of birth. Staff can confirm if they are being held at the county jail. For written records, submit a data request under the Minnesota Government Data Practices Act. The county must respond within a reasonable time and cannot charge more than the actual cost of making copies.
The Minnesota DOC Inmate Locator shows people in the state prison system. If a Pennington County inmate was sentenced to prison, they show up here after being processed by the Department of Corrections. Search by name or DOC number. Partial searches work for common names. The DOC Search Portal adds fugitive lookup tools and victim notification sign-ups.
Court records fill in gaps that jail and prison databases miss. The Minnesota Judicial Branch publishes case data from the 9th Judicial District, which covers Pennington County. You can look up charges, case status, and sentencing outcomes. Putting court records together with inmate population data gives you a more complete picture of what happened in a particular case.
Note: Small county jails may not have online roster tools. Calling the Sheriff's Office is often the fastest way to check if someone is in custody in Pennington County.
Inmate Population Data Access
Arrest data in Pennington County is public. Under Minnesota Statutes Chapter 13, that includes the person's name, age, sex, address, charges, and bail amount. The time and place of arrest, the arresting agency, and the holding facility are all public too. You do not need to provide a reason for requesting this data. Anyone can ask.
Private data includes medical and mental health records, financial details, and security classification information. Under Minn. Stat. 13.85, corrections data is classified based on whether release could harm someone or compromise facility operations. Data from open court proceedings is public. The Bureau of Criminal Apprehension maintains statewide criminal histories that include Pennington County booking records. Background checks through the BCA may require fingerprints and a fee.
Jail population reports go to the state under Minn. Stat. 641.05. These reports track how many people are in custody, the types of offenses, and how long inmates stay. For a small county like Pennington, the numbers are modest. But the reporting requirements are the same as they are for big metro counties.
Booking and Jail Standards
Booking at the Pennington County jail works like any other county facility in the state. Staff photograph the person, take fingerprints, and log all charges. Warrant checks go through national and state databases. The booking record joins the inmate population log. Fingerprints feed into the BCA system, linking the person to their criminal history statewide.
Minnesota law sets baseline standards for county jails. Under Minn. Stat. 641.14, inmates must be separated by gender. Juveniles stay apart from adults. Every inmate gets meals, medical care, and access to counsel. The state bans private prisons under Minn. Stat. 641.015, which means all detention in Pennington County is run by the county government. Before release, Minn. Stat. 641.155 requires discharge planning to connect inmates with community resources.
