The Rock County Inmate Population
Rock County does not operate a separate county jail in Luverne. The Rock County Sheriff's Office states that Rock County contracts with the Nobles County Sheriff's Office for jail services. For the Rock County inmate population, that one fact controls the whole lookup path. A Rock County arrest may start with Rock County law enforcement, but the local jail bed, public roster, visitation, mail, phone, and money rules usually run through Nobles County Jail at the Prairie Justice Center in Worthington.
The Rock County inmate population includes local pretrial detainees, people serving local jail sentences, and people held on agency requests while the case is still local. Sentenced felony prisoners leave that county-jail count after commitment to the Minnesota Department of Corrections public viewer. Federal prisoners and immigration detainees are separate again. That split keeps Rock County records work from being a single search box. The sheriff, jail, district court, state DOC, BOP, ICE, VINE, and the sheriff app can all matter for one person's custody trail.
Rock County Inmate Population Statistics
The most reliable local capacity numbers come from the Minnesota DOC adult facility inspection archive and the 2025 Nobles County Jail inspection. The report lists Nobles County Jail as the contract local adult detention facility serving Rock County jail needs. It gives 88 approved secure coed beds and an operational capacity of 79.20 at 90 percent. No official Rock County-owned jail capacity exists because Rock County uses Nobles by contract.
| Measure | Figure | Source / Year |
|---|---|---|
| Nobles County Jail approved secure coed capacity | 88 beds | MN DOC inspection, 2025 |
| Operational capacity | 79.20 at 90 percent | MN DOC inspection, 2025 |
| Rock County-owned jail capacity | Not applicable | Rock County Sheriff contract note, 2026 |
| Minnesota annual local jail bookings | At least 69,000 people | Prison Policy Initiative Minnesota profile |
| U.S. local jail average daily population | 664,800 | BJS Jail Inmates in 2023 |
Rock County Inmate Population Trends
Rock County's official sources did not publish a multi-year average daily population table for Rock County detainees. The trend record is still useful because it shows the facility base behind the Rock County inmate population. Nobles County Jail's bed capacity has stayed tied to the 88-bed approval date carried in the 2025 inspection, while the live roster changes throughout the day as bookings, releases, court holds, and transfers occur.
| Date or period | Indicator | Why it matters |
|---|---|---|
| 08/22/2017 | 88 approved secure coed beds | Capacity date used in the 2025 DOC report. |
| 07/22/2025 | 88 approved beds and 79.20 operational capacity | Annual inspection of the contract jail serving Rock County. |
| 10/01/2024 to 07/23/2025 | 13 juveniles held or processed | JJDPA audit period in the 2025 inspection. |
| 06/18/2026 10:05 AM | Live roster timestamp | The direct Nobles roster was updating current custody, not an archive. |
Who Makes Up the Rock County Inmate Population
The Rock County inmate population is not published with a full local race, sex, age, or average-daily-population breakdown in the official sources reviewed. The Nobles roster shows charge levels and agency lines, but it does not show DOB, sex, race, home address, housing unit, or bond. The 2025 inspection confirms a secure coed local adult jail that must classify and separate male and female inmates, minimum, medium, and maximum classifications, administrative or disciplinary segregation, special-management cases, work release/community custody, and juveniles who cannot be placed as adults.
- Pretrial and local sentence custody - Rock County detainees are held through the Nobles contract jail while local cases or jail sentences are active.
- Other-agency holds - The roster may show holding-agency language when a person is kept for another county, state, federal, or similar authority.
- Adult men and women - The inspection identifies the jail as secure coed and governed by classification and separation rules.
- Limited juvenile processing - The inspection recorded 13 juveniles held or processed during the JJDPA review period, with zero violations.
National and state context helps frame the missing local detail. The Prison Policy Initiative reports that 67 percent of people in Minnesota jails have not been convicted, while the Bureau of Justice Statistics reported that 70 percent of the U.S. jail population was unconvicted at midyear 2023. Those figures are not Rock-only counts. They explain why a Rock County jail roster entry is often a pretrial custody record, not proof of guilt.
Rock County Jail Capacity and Overcrowding
No official overcrowding order, consent decree, new Rock County jail construction project, or Rock/Nobles contract-jail population lawsuit was located in the research. The 2025 inspection did not reduce capacity. It did place Nobles County Jail on annual inspections and noted facility-aging issues, water damage in shower areas, separation and classification concerns, training documentation gaps, admissions policy updates, and medication-refrigeration checks.
The same inspection described the jail as clean overall and free of major defects. That is important for wording. The Rock County inmate population should not be described as overcrowded without a sourced count showing the population exceeded capacity. The stronger, sourced statement is that Rock County relies on a contract facility with an 88-bed approved secure coed capacity, annual DOC inspection, and documented corrective-action items.
Laws Governing Rock County Inmate Population
Minnesota public-data law explains why some Rock County inmate population facts are public and why other details stay limited. Jail rosters, booking photographs, arrest data, commitment records, and detention data come from several statutes and rules. The reader still needs to start with the office that holds the record. Rock County keeps local law-enforcement and warrant material, Nobles County Jail keeps jail custody records, and the court keeps formal case records.
Key Minnesota rules:
Minn. Stat. section 13.03 makes government data public unless another law classifies the data differently.
Minn. Stat. section 13.82 covers law-enforcement data, including arrest data, warrant index treatment, and booking photographs.
Minn. Stat. section 641.05 requires sheriffs to keep permanent jail commitment records.
Minnesota Rules Chapter 2911 sets local adult detention facility standards for admissions, records, classification, health, food, security, and capacity.
Rock County State Prison Population
No Minnesota DOC state prison was located in Rock County. Once a Rock County defendant is sentenced to prison and committed to the Commissioner of Corrections, the main search path changes from the Nobles jail roster to MNDOC. The state locator can be searched by name or MNDOC Offender ID and covers adults still under DOC jurisdiction, including some people released from prison but under supervision.
The MNDOC search page and public viewer are not county jail tools. Newly sentenced people may take several business days to appear. That delay can create a gap after a Rock County court sentence: the person may be leaving county jail custody, not yet visible in DOC, and no longer shown as a current Nobles roster entry. VINELink can help with custody notification, but it does not replace direct agency verification.
Search Rock County Inmate Population
The current local custody path starts with the Nobles County inmate listing page or the direct roster frame. The roster is a current list, not a form-driven search database. It shows visible inmate blocks with a booking image, name, booking date, agency, charge type, charge description, and a last-updated timestamp.
- Open the Nobles County inmate listing or direct roster frame.
- Use the browser find command to search a last name, since the roster has no search fields.
- Read the agency and charge rows to see whether Rock County or another agency is tied to the custody entry.
- Call Nobles County Jail if the roster is missing bond, housing, court date, or release details.
- Check MNDOC, BOP, or ICE if the person is sentenced, federal, or in immigration custody.
The Rock County Sheriff's Office also publishes related links for inmate listing, outstanding warrants, VINE, and the RCSO Phone App. The app is official and free, but the store listings describe reports, tips, news, and public-safety information rather than a full roster output. Check the app's current menu before treating it as a separate inmate-search source.
Current Rock County Inmate Lookup
The direct roster is plain but useful. The inspected page did not have Last Name, First Name, booking number, date, agency, or facility filters. It is a free public listing with no login. If a Rock County arrest is too new to show, the best next step is a phone check with the jail or sheriff rather than assuming the person is not in custody.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| None | No form field | Not applicable | The official roster is a direct list/iframe. Use browser Find or scan the visible entries. |
| Visible roster fields | Static listing | Not applicable | Mugshot, name, booking date, agency, charge type, description, and last-updated timestamp. |
The Rock County Sheriff's Office page is also the local source for Sheriff Matthew Sorenson, the Luverne law-enforcement office, public-safety links, and the jail-service contract note. Rock County arrest or warrant questions may belong there even when the jail record sits with Nobles.
Rock County Inmate Record Fields
A Rock County inmate record on the Nobles roster is enough to confirm current custody and broad charge context, but it is not a full booking file or court case. The public frame inspected showed each visible person with a booking-photo image, name, booking date, and a charge table. It did not show bond, court date, release date, housing unit, booking number, DOB, height, weight, race, sex, address, judge, or statute number.
| Field | What It Shows |
|---|---|
| Mugshot image | One public booking image next to the visible current inmate entry. |
| Name | Full name in last-name-first display order. |
| Booking date | Date booked into Nobles County Jail. |
| Agency | Arresting, charging, or holding agency tied to that row. |
| Type | Charge level or hold class, such as felony, gross misdemeanor, misdemeanor, or unknown. |
| Description | Plain-language charge, probable-cause note, unsentenced charge, or hold description. |
For a visual example, the successful capture of the direct Nobles roster interface shows the roster style used for Rock County detainees held under the contract.
The image illustrates why phone and court follow-up matter: the public roster shows custody and charge summaries, but not bond or the next court date.
Rock County Jail vs Prison Lookup
County jail, state prison, federal prison, and immigration custody are different systems. A person arrested by Rock County may first appear in the Nobles County Jail roster. A person sentenced to prison after a Rock County case should be searched in MNDOC. Federal defendants use federal channels, and immigration custody uses ICE. A detainer or hold can also make release more complex than the local charge row suggests.
| Custody type | Where to search | What it covers |
|---|---|---|
| Local jail custody | Nobles County inmate listing | Pretrial and sentenced local jail inmates held under the Rock/Nobles contract. |
| State prison or supervision | MNDOC public viewer | Adults committed to the Commissioner of Corrections and still under DOC jurisdiction. |
| Federal custody | BOP Inmate Locator or USMS District of Minnesota | Federal inmates from 1982 forward and federal custody logistics. |
| Immigration custody | ICE Online Detainee Locator | Current ICE detainees or some people recently in CBP custody. |
State Federal ICE Inmate Search
State, federal, and immigration tools should be used when the person is not in the current Nobles roster or the custody reason points outside local court. The MNDOC locator searches by name or MNDOC Offender ID. The BOP locations page and locator address federal prison custody, while the nearest BOP residential reentry management source found was RRM Minneapolis. ICE lookup can use an A-number or biographical information, as described by USAGov's ICE detainee instructions.
For custody alerts, Minnesota VINE/VINELink is available. VINE can help track custody status notifications, but it should not be used as the sole proof of release, court date, or bond eligibility. Call the jail or the court for urgent action.
Rock County Detention Facilities
The facility map for this Rock County build resolves to one local detention facility. The jail is outside Rock County, but it is the primary local jail channel because Rock County contracts jail service to Nobles County.
- Nobles County Jail - regional/contract local adult detention facility for Rock County pretrial detainees, local sentenced inmates, Nobles County detainees, other-agency holds, adult men and women, and limited juvenile holds under the rural exception.
The Reliance facility page for Nobles Prairie Justice Center supports jail phone and video services connected with this facility.
That service source fits the same contract-jail structure: Rock County users may search from Rock County, but jail communication runs through Nobles County systems.
