Find Inmates in Marquette County
Marquette County inmate population records are maintained by the Marquette County Sheriff's Office in the city of Marquette. As the largest county by area in Michigan and the largest in the Upper Peninsula, Marquette County covers a wide geographic region with its own jail and local custody system. This page explains how to find someone held at the Marquette County Jail, how state tools like OTIS and VINELink work for this county, and how to request inmate records through Michigan's public records process.
Marquette County Overview
Marquette County Jail and Inmate Population
The Marquette County Jail is operated by the Marquette County Sheriff's Office and holds people who are awaiting trial, serving short sentences, or detained on other legal matters in the county. The facility is located in the city of Marquette, which is the largest city in the Upper Peninsula. The jail serves the entire county, which stretches across a large portion of the central Upper Peninsula and is the biggest county by land area in the state of Michigan.
Because Marquette County is both large in area and more populated than many other Upper Peninsula counties, the jail handles a broader range of cases. The sheriff's office processes bookings from various law enforcement agencies across the county, including state police posts and tribal law enforcement. If someone was arrested anywhere in the county, they are most likely processed and held at this facility in the city of Marquette. The jail serves as the central detention point for the entire county regardless of where the arrest took place.
VINELink is available for Marquette County, giving the public a way to track custody status changes automatically. For state prison inmates, the OTIS database is the right tool once someone has moved from the county jail to a Michigan Department of Corrections facility.
How to Find Marquette County Inmates
To find out if a specific person is currently held at the Marquette County Jail, call the Marquette County Sheriff's Office at (906) 225-8435. Have the full name ready, along with a date of birth if you have it. Staff can check the current inmate roster and provide basic custody information. There is no public online jail roster for Marquette County at this time, so a direct call is the most reliable method for county jail inquiries.
VINELink covers the Marquette County Jail and gives you a way to set up automatic custody notifications. You can register at vinelink.com or call 1-800-770-7657. Once registered, you receive alerts by phone, text, or email whenever the custody status of a registered person changes. This is useful for tracking transfers, releases, or changes in custody without making ongoing phone calls. The service is free and confidential.
If someone was convicted and sentenced to a Michigan state prison after being held in Marquette County, use OTIS to search for them. The Offender Tracking Information System at mdocweb.state.mi.us is a free public tool run by the Michigan Department of Corrections. It covers all current and recently released state inmates but does not include people still held at county jails.

Michigan OTIS: State Prison Inmate Lookup
OTIS is the Michigan Department of Corrections' public inmate search tool. It covers people who are currently in a state prison or who have been released from state custody. If someone from Marquette County was convicted of a felony and sent to a state facility, OTIS is where you will find them. Access the system at mdocweb.state.mi.us.
Search by name or MDOC number. Results include the person's current facility, earliest release date, and a photo when available. The system is free to use and does not require an account. It updates as people move through the state corrections system. OTIS does not include county jail inmates, so if someone is still at the Marquette County Jail, you need to call the sheriff's office instead. More information about MDOC and its programs is at michigan.gov/corrections.

Requesting Marquette County Inmate Records
You can formally request jail records from the Marquette County Sheriff's Office under Michigan's Freedom of Information Act. MCL 15.231 gives any member of the public the right to request access to government records. The sheriff's office must respond within five business days and may extend that to ten days for complex requests.
Put your request in writing. Be specific about what records you are asking for: the person's name, the time period, and the type of records, such as booking logs, custody history, or release documentation. Send your written request to 236 W. Baraga Ave., Marquette, MI 49855. There may be a fee for copying and processing, and the office will let you know before proceeding if costs apply.
Some records may be exempt from release under FOIA. Active investigation files, personal information that could put someone at risk, and certain sensitive records may be withheld. The office must identify the specific exemption in writing if any part of your request is denied. MCL 801.1 establishes the county sheriff's legal authority over jail operations and records, which shapes what is available for public access. MCL 800.31 sets operational standards that apply to all county jails in Michigan.
Marquette County Court Records
Criminal cases in Marquette County are handled by the 25th Circuit Court and local district courts. Court records are separate from jail records but often give context for why someone is in custody. The MiCOURT case search portal at courts.michigan.gov allows name and case number searches for courts across Michigan, including those in Marquette County.
Court records can show charges, bond amounts, hearing dates, and case outcomes. If you want to understand the legal circumstances behind a person's custody, checking MiCOURT alongside calling the sheriff's office gives you a more complete picture. The Marquette County Clerk can also provide information on specific cases if needed. For statewide criminal conviction history, ICHAT at michigan.gov/msp/services/ichat is available for a small fee per search.
Michigan State Police: Criminal Records and Registry
The Michigan State Police runs the Internet Criminal History Access Tool, called ICHAT. This is a paid search that gives you access to Michigan conviction records by name. It does not show current custody status, but it can confirm whether someone has a criminal record in the state. There is a small fee per search, and results cover the full state, not just Marquette County.
The Michigan State Police also maintains the Sex Offender Registry at michigan.gov. This is a free, public tool that lets you search by name or location for registered sex offenders. It covers all Michigan counties including Marquette. The registry shows current registration status and residential information for registered offenders in the county, which is separate from custody status at the jail. Both ICHAT and the sex offender registry are supplemental tools when researching the full picture around someone connected to the Marquette County inmate population.
