Marquette County, Wisconsin, has about 16,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Marquette County Sheriff's Office and five city 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 District 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 288 arrests for 2025.
Arrests inside five 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:
- Montello, 1,437 residents: 37 arrests reported for 2025.
- Westfield, 1,303 residents: 7 arrests reported for 2023.
- Oxford, 534 residents: 19 arrests reported for 2023.
- Endeavor, 433 residents: 6 arrests reported for 2019.
- Neshkoro, 410 residents: 4 arrests reported for 2019.
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.
How Many Arrests Each Agency Reports in Marquette County
The FBI publishes every agency's monthly arrest counts on the Crime Data Explorer. These are the full-year totals, all offenses, as the FBI held them on October 8, 2026; a year with months missing or not reported is left out.
- Marquette County Sheriff's Office: 288 for 2025, 351 for 2024, 299 for 2023, 394 for 2022, 396 for 2021 and 359 for 2020.

Together, the four agencies with all twelve months of 2023 on file reported 374 arrests that year. The two of them with both 2023 and 2022 complete reported 348 in 2023 against 456 in 2022, down 24 percent.
Neshkoro and Endeavor reported only part of 2023 (7 months and 6 months) and are left out of the totals.
Booking: Where People Arrested in Marquette County Are Held
The county jail is where a person arrested in Marquette County and kept in custody ends up, whichever agency made the arrest, though a city department may hold someone in its own cells first and a person cited and released at the scene is never booked. The jail's record of each person held, with the charges, is a public record of the arrest, and once the person is released or sentenced the record continues in the court file.
On an average day in 2025 the jail held about 30 people, up from about 25 in 2019. Its rated capacity in 2025 was 60 beds, and it ran at 49 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: Wisconsin Circuit Court Access, the free statewide case search of every circuit court, which shows whether charges were filed; the District Attorney, which decides whether an arrest becomes a charge (its page is at marquettecountywi.gov/district-attorney, phone 608-297-3030).
Wisconsin is one of the states that lets anyone look up another person's statewide criminal history: the Wisconsin Online Record Check System lets anyone run a name-based check, through the Wisconsin Department of Justice. 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 Wisconsin Public Records Law the agency must answer as soon as practicable and without delay; the law sets no number of days, and it may charge the actual cost of copying and locating, with no charge for the first $50 of locating.
- An arrest by the Marquette County Sheriff's Office: ask its records unit, reached through the office at 608-297-2115.
- An arrest in Montello, Westfield, Oxford, Endeavor or Neshkoro: the records unit of the agency that reports for that city.
- A defendant who has been charged gets the report through the case: the District Attorney, 608-297-3030, 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
