The Mackinac County Inmate Population
The Mackinac County inmate population is centered on one local detention facility, the Mackinac County Jail in St. Ignace. The jail is run by the Mackinac County Sheriff's Office and holds people after local arrest, people waiting for District Court or Circuit Court action, locally sentenced jail inmates, and people connected to court-ordered tether or house-arrest programs. No official county, state, federal, or ICE source identified a separate state prison, federal prison, immigration detention center, regional jail, or work-release annex physically inside Mackinac County.
That structure matters because the Mackinac County inmate population is not the same as the Michigan prison population. A person arrested by the sheriff, St. Ignace Police Department, Mackinac Island Police Department, Michigan State Police, or another local agency may first be booked into the county jail. If the case later results in a state prison sentence, the custody record moves into the Michigan Department of Corrections OTIS locator. Federal and immigration detention use still other systems. A clean search starts by asking whether the person is in county jail now, in court proceedings, under MDOC supervision, or in federal or immigration custody.
The Mackinac County Sheriff's Office page is the official starting point for local custody contacts. It lists Sheriff Edward M. Wilk's office, the jail phone line, and jail-related payment links. Because no official online county roster was found in the researched sources, the jail phone and written public-record request route carry more weight here than they would in a county with a searchable roster.
Mackinac County Inmate Population Statistics
The strongest county-specific numbers are the jail's rated capacity and older average-daily-population figures cited in the research file. The official jail page states a rated capacity of 28 inmates. A county jail committee report search summary says average daily population rose from 9.1 in 1979 to 25.1 in 2010. Prison Policy Initiative's jail phone-rate appendix lists Mackinac County Jail's 2013 average daily population as 18. No official current online daily population dashboard or roster count was located.
| Measure | Figure | Source / Year |
|---|---|---|
| Mackinac County Jail rated capacity | 28 inmates | Official county jail page, modified 2025 |
| Current online daily population | Not published online in located official sources | No official roster or dashboard found |
| Historical ADP | 9.1 inmates | Jail Committee Full Report search-result text, 1979 |

Mackinac County Inmate Population Trends
The available Mackinac County trend line is useful but limited. It supports a careful statement that the jail had grown close to its rated capacity by 2010, then showed a lower average daily population in the 2013 phone-rate appendix. It does not support a claim about the current 2026 daily population, annual booking total, average length of stay, or demographic split. The county jail committee reports still matter because they show that Mackinac County studied jail population pressure and facility needs using local data.
| Year | ADP / Population Figure | Notes |
|---|---|---|
| 1979 | 9.1 ADP | Jail Committee report search text says ADP rose from this point. |
| 2010 | 25.1 ADP | Close to the 28-bed rated capacity reported by the county jail page. |
| 2013 | 18 ADP | Prison Policy Initiative phone-rate appendix figure. |
| 2025/2026 | Not published online | No official current dashboard, annual report, or public roster count found. |
Capacity is the main caution. A 25.1 ADP against 28 rated beds suggests the jail was operating near capacity during the period studied by the county committee. The 2013 figure was lower. No official current overcrowding order, consent decree, new-jail construction notice, or capacity litigation was located in the researched sources.
Mackinac County Jail Capacity History
The official jail page gives the most local history. The current Mackinac County Jail was built in 1972, replacing an older jail that had been in the basement of the County Courthouse. That detail ties jail custody, court records, and the county complex together at the St. Ignace government campus. The county also says the jail is certified by the Michigan Department of Corrections as meeting local jail and lockup standards.
The same county page reports that in 2009 Mackinac County Jail was the first jail in the country accredited by the American Correctional Association to the Core Jail Standards for jails. That statement should be read as the county's own facility description. It is a meaningful local fact, but it does not replace current custody confirmation, current inspection details, or current population figures. Those still have to come from the jail, county records, MDOC standards, or another official source.
The official jail screenshot in the research capture shows the facility page where the county publishes capacity, visitation, CTEL, JailATM, VINE, and program details: Mackinac County Jail official information.
The page is useful for facility operations, but it does not publish a live online inmate roster or booking-photo list in the researched sources.
Mackinac County Jail Record Laws
Michigan public-record law and jail standards explain why some Mackinac County inmate population records can be requested, while other details may be limited or held in a different system. MCL 15.231 states Michigan's public policy that people are entitled to full and complete information about government affairs. MCL 15.235 sets the response framework that Mackinac County applies through its FOIA public summary.
Key Michigan rules:
MCL 15.231 frames public access to government records, including county records that are not exempt.
MCL 15.235 supports the five-business-day response rule described in Mackinac County's FOIA summary.
MCL 791.262 authorizes MDOC rules and standards for local jails and lockups.
Michigan Administrative Rules for Jails and Lockups address jail operations such as records, sanitation, supervision, health, and safety.
Public access is practical as well as legal. For a real-time custody question, the jail phone is faster than FOIA. For formal charges and hearing dates, the court record is better than a booking entry. For sentenced state custody, OTIS is the right system. For federal or immigration custody, BOP and ICE tools are separate from the Mackinac County inmate population.
Search Current Mackinac County Inmates
No official Mackinac County online jail roster, inmate search page, current-inmate list, recent booking report, or booking-photo feed was located on the official sheriff or jail pages. That changes the search order. The first step for current local custody is the Mackinac County Jail phone line. If the question is about a public booking record rather than immediate custody, use the County Clerk and FOIA Coordinator route.
- Call Mackinac County Jail at (906) 643-7325 for current custody questions.
- Have the full legal name, approximate age or date of birth, arrest date, arresting agency, and any known case or warrant number.
- Ask whether the person is housed at Mackinac County Jail, has bonded out, has been released, or has been transferred.
- Use VINELink for release notifications by selecting Michigan and searching by offender name.
- Use MiCOURT for Mackinac County 92nd District Court once charges or hearings have been filed.
- Use MDOC OTIS, BOP inmate locator, or ICE ODLS only when the person may be outside county jail custody.
| County Roster Field | Status | Notes |
|---|---|---|
| Online roster form | Not located | Mackinac County did not publish an official roster form in the inspected sources. |
| Current booking list | Not located | Use jail phone, FOIA, VINE, and court records. |
| Booking photo feed | Not located | Do not rely on commercial mugshot pages as official county records. |
Mackinac County Inmate Record Requests
When a record is not posted, Mackinac County's FOIA process runs through the County Clerk and FOIA Coordinator. The County Clerk page lists Hillary Vowell at 100 S. Marley, Room 10, St. Ignace, MI 49781. The FOIA public summary says a request may use the county form or any other written form, including letter, fax, or email, as long as it describes the public record well enough for the county to find it.
For a jail record, ask for the specific item rather than a broad file. Useful request terms include booking sheet, arresting agency, booking date and time, jail log entry, charge or hold reason as maintained by the jail, bond information if maintained by the jail, release or transfer date, and booking photograph if not exempt or withheld. Email requests should include "FOIA" or "FOIA Request" in the subject line. The county may grant, deny, grant in part, issue a 10-business-day extension, or point to a free website record within five business days after receipt.
The official County Clerk page captured for the research shows the FOIA links and courthouse contact information: Mackinac County Clerk and FOIA information.
FOIA is not a substitute for urgent custody confirmation. It is the path for records that are public but not posted online.
Mackinac County Court Records After Arrest
Many inmate-search questions are really court-record questions. The Mackinac County Prosecutor page explains that police investigate reported crimes, submit warrant or charging requests, and the Prosecuting Attorney reviews police reports, witness statements, records, and prior history. If probable cause supports a charge, a complaint is filed in District Court and a warrant may be signed by a judge or magistrate.
The 92nd District Court handles arraignment, bail, misdemeanor cases punishable by up to one year in jail, and felony preliminary examinations. At arraignment, the defendant is told the charge, maximum penalty, rights, and bond conditions. A felony case may later be bound over to the 11th Circuit Court, where the County Clerk maintains Circuit Court records. For the court side of the search, use Mackinac County court records after a jail arrest rather than treating a jail booking entry as the final charge record.
State and Federal Inmate Search
MDOC OTIS covers prisoners, parolees, probationers, discharged offenders within the public retention period, and absconders. OTIS is not a Mackinac County jail roster. The OTIS About page says users must enter at least a last name or offender number unless using certain absconder categories. An offender number is the most precise search. Age searches use a plus-or-minus range, and a wildcard can broaden a last-name search when at least three leading letters are supplied.
| Custody System | Where to Search | Use It When |
|---|---|---|
| County jail | Mackinac County Jail phone and FOIA | Recent arrest, local jail custody, booking record, release status. |
| State prison or supervision | MDOC OTIS | Prison, parole, probation, absconder, or discharged MDOC record. |
| Federal prison | BOP inmate locator | Federal inmates from 1982 to present. |
| Immigration detention | ICE ODLS | Immigration detainee location by A-number/country or biographical data. |
The MDOC search screenshot in the research capture shows the statewide fields used for sentenced custody and supervision: MDOC OTIS offender search.
OTIS can explain a state sentence or supervision status, but it should not be used as the first check for someone arrested in Mackinac County today.
Mackinac County Detention Facilities
The Mackinac County facility map resolves to one county jail page. Other law enforcement agencies may make arrests, but the researched sources did not identify separate city lockups with public inmate systems. State prisons, BOP facilities, and ICE facilities are outside the county facility map and are searched through their own statewide or federal locators.
- Mackinac County Jail - the local jail for pretrial detainees, locally sentenced jail inmates, court commitments, and related tether or house-arrest program participants when ordered through the courts.
- Booking
- Jail intake after arrest or court commitment.
- Arraignment
- The first court appearance where charges, rights, and bond may be addressed.
- Detainer
- A hold or request from another jurisdiction or agency.
- OTIS
- Michigan's state offender locator for MDOC custody and supervision.
Mackinac County Arresting Agencies
Local arrests can begin with the Mackinac County Sheriff's Office, St. Ignace Police Department, Mackinac Island Police Department, Michigan State Police, or another authorized agency. The prosecutor page says police may arrest on the spot when a crime occurs in an officer's presence or when probable cause supports certain misdemeanors or any felony. The officer then submits a warrant or charging request to the Prosecuting Attorney.
St. Ignace Police covers the city area and is dispatched through tri-county Central Dispatch. Mackinac Island Police has a seasonal public-safety pattern, with summer patrol on foot and bicycle and winter work for the smaller year-round population. These agencies are part of the arrest pipeline, but neither researched police page published a separate jail roster. After booking, custody and release questions route back to Mackinac County Jail.
Mackinac County Inmate Population FAQ
How big is the Mackinac County inmate population?
The official jail page gives a rated capacity of 28 inmates. Older research figures list 25.1 ADP in 2010 and 18 ADP in 2013. No official current online daily population dashboard was found, so current population should be confirmed through the county rather than estimated.
Can I search the Mackinac County inmate population online?
No official county jail roster or current-inmate search page was located in the researched official sources. Start with the Mackinac County Jail phone line for current custody, then use FOIA, VINELink, MiCOURT, OTIS, BOP, or ICE depending on the record needed.
Where are Mackinac County state prisoners listed?
Sentenced state prisoners and people under MDOC supervision are searched in OTIS. OTIS is statewide and separate from the Mackinac County Jail. A person may move from local jail to MDOC after sentencing in a felony case.
Does Mackinac County publish mugshots?
No official Mackinac County mugshot gallery or booking-photo feed was found. Booking photos, when releasable, should be requested through the jail and county FOIA process. The Mackinac County jail mugshots page explains that route.
