Pennington County Inmate Population Overview
The official facility map for Pennington County identifies one local detention facility: the Pennington County Jail / Pennington County Correctional Facility. It is operated by the Pennington County Sheriff's Office in Thief River Falls and holds adult men and women arrested by local agencies, people awaiting court action, sentenced local inmates, Huber or work-release participants, and some boarded inmates from other counties. No separate city jail, state prison, federal prison, or ICE detention center was located inside Pennington County in the official sources reviewed.
The local jail count changes as arrests, releases, court orders, bond decisions, and transfers occur. A new booking enters the Pennington County inmate population after intake at the jail. A sentenced felony prisoner may later leave the county count and move into the Minnesota Department of Corrections system. Federal and immigration custody are also separate from the county roster unless a person is physically housed at the county jail under a hold or boarding arrangement.
The sheriff's official jail page is one of the best local sources for the facility itself. The page describes an indirect-supervision jail with seven housing units and a mission to provide safe, secure, and humane custody while offering programs that can help inmates improve themselves. The MNDOC inspection record adds the licensing and compliance view, while the public roster gives a current snapshot of people in custody.
Pennington County Inmate Population Statistics
Pennington County does not publish a stand-alone jail population dashboard or annual booking report in the official material reviewed. The strongest sourced figures are capacity and inspection numbers from the Minnesota Department of Corrections, the public roster count inspected on June 18, 2026, and the U.S. Census estimate for county population. Those figures should be read as different types of data, not as one daily average. The roster count is a point-in-time custody snapshot, while approved capacity is the bed count authorized by jail licensing.
| Measure | Figure | Source / Year |
|---|---|---|
| Approved jail capacity | 92 secure coed beds | MNDOC Pennington County Jail inspection, inspected April 30, 2025 |
| Operational capacity | 82.80 beds at 90 percent | MNDOC 2025 inspection |
| Housing units | 7 | Sheriff Corrections page, accessed June 18, 2026 |
| Live roster count | 38 visible rows | Official Pennington County Inmate Search, inspected June 18, 2026 |
| County population | 13,686 estimate | U.S. Census QuickFacts, July 1, 2025 estimate |
| Annual bookings | Not located | Not published in official Pennington sources reviewed |
Pennington County Jail Population Trends
The available trend record is narrow but useful. The MNDOC inspection report traces the jail's approved secure capacity to an effective date in 2018, then reports operational capacity in the 2025 inspection cycle. The public roster count from June 18, 2026 provides a later custody snapshot. Because no official average daily population or annual booking series was located, the Pennington County inmate population should not be described as rising or falling over time from the available research alone.
| Year or Date | Population or Capacity Marker | Notes |
|---|---|---|
| July 12, 2018 | 92 approved secure coed beds | Capacity effective date listed in the MNDOC 2025 inspection report. |
| April 30, 2025 | 82.80 operational capacity | MNDOC uses 90 percent of approved capacity as the operating capacity figure. |
| June 18, 2026 | 38 current roster rows | Point-in-time count from the public roster grid, not an official average daily population. |
That gap matters. A reader comparing jail size, crowding, and jail use should not treat one roster snapshot as a yearlong average. The responsible use of the sourced numbers is to separate bed capacity, live custody count, and county population. Using those figures together gives context without inventing a trend that the records do not support.
Who Makes Up the Pennington County Inmate Population
The official roster records sex, race, age, height, weight, hair color, eye color, skin tone, date of birth, and cell location for people in custody. The roster inspected for the research contained both male and female rows and race codes including W and I. Exact demographic totals should not be turned into a long-term county profile unless the county publishes a formal report or a fresh roster snapshot is analyzed at the time of use.
- Pretrial detainees: Adults booked after arrest may be held while waiting for first appearance, bond review, or later court dates.
- Sentenced local inmates: Short local sentences may remain at the Pennington County Jail when the court orders local custody.
- Huber and work release: Approved inmates may keep employment or education ties while serving under jail rules.
- Boarded inmates: The fee schedule includes inmate boarding and high-risk offender boarding rates, so some nonlocal custody may appear.
- State prison transfers: Sentenced felony prisoners are searched in MNDOC after transfer, not on the county roster.
The 2025 MNDOC inspection also adds a juvenile custody fact. Pennington County Jail had approval for delinquent juvenile holds up to 24 hours, excluding weekends and holidays, under a rural exception. The same report says the jail held or processed zero juveniles during the federal fiscal year beginning October 1, 2024.
Pennington County Jail Capacity
Capacity is a licensed jail figure, not just a bed count. The MNDOC 2025 inspection classifies Pennington County Jail as a local adult detention facility governed by Minnesota Rule 2911. The report lists 92 approved secure coed beds and an operational capacity of 82.80 beds, calculated at 90 percent. The facility is on biennial inspection status, with operating authority from June 1, 2025 through May 31, 2027.
No official recent consent decree, DOJ investigation, closure order, or new jail construction document specific to Pennington County, Minnesota was located. The 2025 inspection did identify mandatory-rule issues involving missing signed property sheets in two reviewed inmate files and missing medical-screening elements. A later MNDOC corrective action response letter dated July 22, 2025 stated that adequate corrections had been made and that MNDOC would continue monitoring compliance.
The official jail page describes seven housing units. Each unit includes video visitation, telephones, a common television, gaming and dining tables, and a natural-light source. That housing-unit detail helps explain how the Pennington County inmate population is managed inside the jail, while the capacity figure explains the licensed upper limit.
Pennington County Inmate Records Law
Minnesota law controls which jail and law-enforcement records are public. For Pennington County, the practical rule is that current custody starts with the official roster, booking and incident records may require the sheriff's Records Division, and court-filed charges are found through the courts. Some records can be withheld when a case is active, sealed, confidential, or not remotely accessible.
Key Statutes:
Minnesota Statutes section 13.03 says public government data must be accessible unless a law classifies it otherwise.
Minnesota Statutes section 13.82 makes many arrest data points public, including custody location and release information, while active investigative data can be restricted.
Minnesota Statutes section 241.021 gives the Commissioner of Corrections authority to inspect and license correctional facilities.
Minnesota Rules chapter 2911 sets local adult detention standards for admissions, records, security, inmate welfare, medical screening, and facility operations.
Pennington County State Prison Transfers
No MNDOC prison is located in Pennington County. When a Pennington County criminal case results in a state prison sentence, the person leaves the county jail system and enters the statewide Minnesota Department of Corrections process. The county roster may stop showing the person after transfer, so the MNDOC public locator becomes the main place to check prison or supervision status.
MNDOC warns that newly sentenced people can take several business days to appear. That delay is normal and does not mean the person is still in the county jail. For release notifications, MNDOC links victims and public users to Minnesota HAVEN and VINELink custody notification tools.

Search Pennington County Inmate Population
The current local custody search is the Pennington County Inmate Search. It is a free public roster hosted on a ProPhoenix platform. It covers people currently in the county jail, not every person with a Pennington County criminal case and not every person sentenced to MNDOC. The roster search is still the first stop for a recent arrest because it can show a booking number, name, physical descriptors, cell location, court date fields, charge grids, bail or fine labels, holds, and an image link in the detail view.
A broad search works best when the spelling is uncertain. The search screen accepts last name, first name, gender, and DOB year. If a person was arrested very recently and does not yet appear, call Corrections rather than assuming the person was released. Intake, identity checks, medical screening, housing assignment, and roster updates can take time.
- Open the official Pennington County Inmate Search.
- Enter a last name or first name. Use fewer fields if the spelling may vary.
- Add gender or DOB year only if the result set is too broad.
- Use Search to run the query, then review the result grid.
- Double-click or open the row to view case details, charges, holds, bail labels, and the image link if available.
- If the person was sentenced to prison, check MNDOC instead of the county roster.

Pennington County Roster Search Fields
The Pennington County roster does not require a paid login. It provides a simple field set and a visible results grid. The research inspection found that DOB is entered as a year, not a full birth date. Gender can be left at Unknown when a name search is enough. The Search and Clear buttons control the query and reset process.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Last Name | Text | Unspecified | Free-text last name field. Try partial spelling if the full name is uncertain. |
| First Name | Text | Unspecified | Free-text first name field. It can be combined with last name. |
| Gender | Dropdown | Optional or unspecified | Options shown are Unknown, Male, and Female. |
| DOB (yyyy) | Text | Optional or unspecified | Four-character year field, useful when names are common. |
| Search / Clear | Buttons | Not applicable | Search submits the query. Clear resets the fields. |
Past Pennington County Inmate Records
The public roster is a current in-custody tool. It is not a complete archive of every past booking, release, or court charge. For a person who is no longer listed, the next step depends on the reason. A released local inmate may require a public-records request through the sheriff's Records Division. A sentenced prison inmate may be in MNDOC. A formal charge record should be searched through Minnesota Court Records Online or Pennington County District Court.
The Records Division is open to the public Monday through Friday from 8:00 a.m. to 4:30 p.m. Photo identification is requested for report copies, and the sheriff recommends calling before coming in. Active investigations cannot be released. That means a booking event may be confirmed in one channel while reports, photos, or investigative details remain restricted for a time under Minnesota law.

Pennington County Inmate Record Fields
A Pennington County inmate record can have both visible grid fields and detail fields that appear after selecting a row. The visible grid inspected showed booking number, name, height, and weight, while DOB appeared as month and year in the result column. Underlying and detail data can include SPN, age, sex, race, cell location, court date, charge details, hold reason, agency, bail or fine amount, custody date, booking status, and an inmate image link.
| Field | What It Shows |
|---|---|
| Booking Number | The event number for the jail stay. Examples in the research used ten-digit year-prefixed numbers. |
| Name and DOB | Name appears in the result row. DOB may appear as month/year publicly, with full date in underlying data. |
| SPN and CJIS Numbers | System or justice identifiers used by the jail software and agencies. |
| Cell Location | Housing assignment such as upper or lower unit locations. |
| Charges | Detail grid fields can include case number, charge, description, severity, bail amount, type, court date, and court branch. |
| Holds | Hold reason and agency fields can show another case or agency interest that affects release. |
| Mugshot/Image | The detail section includes a link labeled Click to View Image, while the result row itself has no thumbnail. |
Pennington County Jail vs Prison Lookup
County jail custody and state prison custody are often confused. Pennington County Jail is the local holding facility for pretrial adults, sentenced local inmates, program inmates, and some boarded inmates. MNDOC handles adults committed to the Commissioner of Corrections after a state-prison sentence. Federal and immigration custody are separate systems and should not be searched through the Pennington roster unless the person is physically held at the county jail.
| County Jail | State Prison | Federal or ICE | |
|---|---|---|---|
| Who is held | Pretrial, short sentence, Huber/work release, local custody | Sentenced adults under MNDOC jurisdiction | Federal prisoners or immigration detainees |
| Run by | Pennington County Sheriff's Office | Minnesota Department of Corrections | BOP, ICE, U.S. Marshals, or federal partners |
| Where to search | Pennington County Inmate Search | MNDOC public locator | BOP locator or ICE ODLS |
| Best use | Current county custody and booking details | Prison or supervision status after transfer | Federal custody status, not county booking photos |
Pennington County Detention Facilities
The resolved facility map has one detention facility page for this county. Thief River Falls Police Department arrests appear to route through the county Law Enforcement Center and jail rather than a separate city roster. State prison, federal prison, and ICE searches use statewide or federal tools because no such facility was found in Pennington County.
- Pennington County Jail / Pennington County Correctional Facility holds adult male and female pretrial detainees, sentenced local inmates, Huber or work-release eligible inmates, and some boarded inmates.
The jail's location in the Law Enforcement Center also matters for records access. The sheriff's public pages place the Sheriff's Office, Corrections, and Records Division in the same local building, though visits, records requests, and court hearings follow different rules and entrances.
Pennington County Jail Programs
The sheriff's jail page says staff plan constructive prisoner time to support safety and order. Local programming includes religious services and counseling, education, substance-abuse meetings, and work assignment programs. Sentence to Serve is described as a Department of Corrections program for nonviolent offenders who can work on projects that benefit the community and surrounding areas.
Huber and work release can allow eligible people to maintain employment or education while housed at the jail. The Huber and work-release materials include fee and property rules, and the corrections fee schedule lists Huber charges. These programs do not mean a person is free from custody. They are controlled jail statuses tied to eligibility, court orders, facility rules, and staff approval.
