Search the Martin County Inmate Population

The Martin County inmate population is centered on the local jail in Fairmont, while sentenced prison, federal, and immigration custody records sit in separate systems. A Martin County inmate search starts with the current county jail roster, then moves to state and federal locators when the person is not in local custody. The Martin County inmate population also reflects jail capacity, booking status, court holds, release decisions, and transfers. For current and past custody questions, search the Martin County inmate population through the roster, records office, court records, and statewide corrections tools.

The Martin County Inmate Population

The Martin County inmate population is held in one local detention facility: the Martin County Jail, operated by the Martin County Sheriff's Office. The jail handles adults arrested in Martin County, people awaiting first appearance or later hearings, short local sentences, transfer holds, and limited juvenile holding allowed under state rules. It is not a state prison. A person sentenced to the Minnesota Department of Corrections moves into a statewide custody system and should be searched through the MNDOC public locator, not only through the county roster.

The best current count comes from the official jail roster PDF because Martin County does not publish a separate live population dashboard. The roster inspected for the research file was current as of June 18, 2026 at 6:10 a.m. and contained 18 numbered entries. That count is a roster snapshot, not an average daily population. Arrests, releases, bond changes, court orders, warrants, sentenced status, and transfers can change the Martin County inmate population during the same day.


Martin County Inmate Population Statistics

Minnesota DOC inspection reports provide the strongest official capacity figures. The 2026 inspection identifies the Martin County Jail as a jail facility with 32 approved secure coed beds and 25.60 operational beds, using the state 80 percent operational-capacity calculation. The same inspection covered authority to operate from May 1, 2026 through April 30, 2027. Official sources reviewed did not publish annual bookings or average daily population, so those figures are not estimated here.

Who the Martin County Jail Counts

The public roster does not publish a full demographic profile of the Martin County inmate population. It shows age, but not race, sex, ethnicity, home address, date of birth, housing unit, or custody-classification level. In the inspected roster, visible ages ranged from 18 to 63. The roster statuses showed a mix of pending, bail set, sentenced, and case-dismissed or not-guilty-style status text, but the county did not publish a pretrial-versus-sentenced summary.

  • Local custody: adults booked after Martin County arrests, warrants, court commitments, and short local sentences.
  • Sentenced prison custody: people committed to MNDOC after sentencing, searched through the state locator.
  • Federal custody: federal inmates searched through BOP, with federal pretrial detainees sometimes held under U.S. Marshals arrangements.
  • Immigration custody: searched through ICE, with no ICE detention facility found in Martin County.

Martin County Jail Capacity

The 2026 DOC inspection places the June roster snapshot below both approved and operational capacity. The facility remains on annual inspection status because of physical-plant concerns, not because the research found a current overcrowding order. Inspection notes point to narrow corridors, potential ligature points from cell bars, non-ADA concerns noted in 2024, limited medical-office space, sight-line problems, and old security electronics. Later inspections also credit improvements such as cameras, emergency call buttons, recreation equipment, and a program schedule.

The population count should not be read as a health or safety rating by itself. Minnesota DOC inspection and licensing rules cover much more than the number of people in beds. They also address admissions, records, programs, medical screening, staffing, physical plant, and reporting. For Martin County, the official inspections are the key source for capacity, facility condition, and authority to operate.


Laws on Martin County Jail Records

Minnesota law separates public access from custody control. A jail roster can be public while some medical, safety, investigation, or security data remains private. That distinction is why Martin County can publish a current roster entry while withholding other details from a public PDF. It also explains why court records, BCA conviction history, DOC records, and booking photos do not always show the same facts at the same time.

Key Minnesota rules:

Minn. Stat. section 13.03 treats government data as public unless a law classifies it otherwise.

Minn. Stat. section 13.82 covers law-enforcement arrest data and generally public booking photographs, with active-investigation limits.

Minn. Stat. section 13.85 protects some corrections and detention data from release.

Minn. Stat. section 641.05 requires sheriffs to keep a permanent jail inmate record.

Minn. Stat. section 241.021 gives DOC inspection and licensing authority over correctional facilities.



Martin County Roster Fields

Because the roster is a PDF report, the search fields are really the PDF's visible text plus the viewer's find function. There are no dropdowns, booking-number filters, wildcard search tools, login prompts, or paid county search fields. The public report gives enough detail to identify a current custody entry, but it does not function like a full jail-management profile.

Past Martin County Inmate Records

The roster is current-facing. It should not be treated as a full archive of everyone booked into Martin County Jail. If a person has been released, transferred, or sentenced to state prison, the current roster may not show them. For booking records, arrest reports, or a booking photo not posted online, use the Sheriff's Records Department at the Law Enforcement Center. The records page says photo ID is required, active investigations cannot be released, and fees may apply where allowed.

The Sheriff's Records page is the local fallback when the roster does not answer the question.

That records channel matters for past custody questions because the public PDF is not an archive search tool.


Martin County Jail vs Prison Lookup

Many failed searches happen because the wrong custody system is being used. Martin County Jail is for local jail custody. MNDOC is for people committed to the Commissioner of Corrections and still under DOC jurisdiction, including prison or supervision. BOP covers federal inmates from 1982 to present. ICE covers certain immigration detainees. These systems do not merge into one county search.

Federal BOPFederal inmates in BOP custodyBOP inmate locator
ICEImmigration custody covered by ODLSICE Online Detainee Locator

Martin County Custody Notifications

Martin County Jail information also points to VINE for custody status and notification service. Minnesota VINE/VINELink can send release, transfer, or escape notifications, but the jail page warns that VINE should not be the only safety tool. For state prison custody, MNDOC uses Haven for notification of custody changes, release, escape, apprehension, and supervision changes. No confirmed Martin County, Minnesota sheriff or local police mobile app was found for jail roster, warrant, or most-wanted lookup.


Martin County Detention Facilities

The facility map for Martin County has one local detention facility. State prisons, federal prisons, and ICE detention facilities identified during research are outside Martin County. The single local facility still connects several agencies because city police, the sheriff, state patrol, court orders, and outside transfer paths can all feed into local custody.

Martin County Inmate Population FAQ

Where should a Martin County inmate search start?

Start with the official jail roster PDF for current local custody. If the person is not listed, use the jail phone channel, Sheriff's Records Department, VINE, MNDOC locator, BOP locator, or ICE locator depending on the likely custody type.

Does Martin County have a state prison?

No Minnesota DOC prison was found in Martin County. Sentenced prison records belong in the statewide MNDOC locator, while the county roster remains the local jail source.
