Marquette County, Michigan, has about 68,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Marquette County Sheriff's Office, six city agencies and two campus, state or other agencies. An arrest leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the Prosecuting Attorney files charges, a case in the Marquette County Circuit Court. This guide says who keeps each one, what it costs and who may see it, with the arrest counts each agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies, cities and common questions.

Who Makes Arrests in Marquette County
The Marquette County Sheriff's Office is the county agency that reports arrests to the FBI for Marquette County. It reported 225 arrests for 2025.
Arrests inside four of the county's cities are reported to the FBI by an agency of the city's own, listed here with the Census population and what each reported:
- Marquette, 21,845 residents: 417 arrests reported for 2025.
- Ishpeming (township), 6,207 residents: 0 arrests reported for 2024.
- Ishpeming, 6,207 residents: 297 arrests reported for 2025.
- Negaunee, 4,676 residents: 71 arrests reported for 2025.
A city on that list is reported separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
The FBI's agency list also places these agencies in Marquette County: Northern Michigan University (campus police); the Marquette County State Police (state police).

Booking: Where People Arrested in Marquette County Are Held
A person kept in custody after an arrest in Marquette County is held at the county jail, whichever agency made the arrest, apart from the short stay some city departments' own holding cells allow; a person cited and released at the scene is not booked at all. The jail's record of each person held, with the charges, is a public record of the arrest, and the court file takes over from there.
On an average day in 2020 the jail held about 62 people, down from about 130 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 160 beds, and it ran at 81 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.

How to Find Out About an Arrest in Marquette County
An arrest in Marquette County can be traced in two places, depending on where the case stands: MiCOURT Case Search, the Michigan courts' statewide case search; not every court has joined, which shows whether charges were filed; the Prosecuting Attorney, which decides whether an arrest becomes a charge (its page is at co.marquette.mi.us/departments/prosecutor_s_office/index.php, phone (906) 225-8310).
Michigan is one of the states that lets anyone look up another person's statewide criminal history: ICHAT lets anyone search public criminal history by name, for $10 a search, through the Michigan State Police. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
Getting a Copy of an Arrest Record in Marquette County
The report of an arrest is released by the agency that made it; the jail and the court hold their own records of the same event, but not the report. Under the Michigan Freedom of Information Act the agency must answer within 5 business days, with a 10-day extension, and it may charge labor and copying, at rates the law caps.
- An arrest by the Marquette County Sheriff's Office: ask its records unit, reached through the office at (906) 225-8435.
- An arrest in Marquette, Ishpeming (township), Ishpeming or Negaunee: the records unit of the agency that reports for that city.
- An arrest by Northern Michigan University or the Marquette County State Police: the records office of the agency involved.
- A defendant who has been charged gets the report through the case: the Prosecuting Attorney, (906) 225-8310, handles discovery for pending cases.
- Your own statewide record: the same request described above, for your own name.
Cities in Marquette County: Who Reports the Arrests
The FBI lists a separate arrest reporting agency for four of the three cities in Marquette County: Marquette, Ishpeming (township), Ishpeming and Negaunee. The FBI's list also carries the Forsyth Township Police Department and the Chocolay Township Police Department as city agencies in Marquette County; Forsyth Township and Chocolay Township are not among the cities above.
Wherever in the county the arrest happens, a person kept in custody goes to the county jail and the case goes to the Marquette County Circuit Court.
