Every office link was opened and checked against the office's own site between September 23, 2026 and September 30, 2026.
Winnebago County, Wisconsin, has about 173,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Winnebago County Sheriff's Office, six city agencies and one campus agency. 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 Winnebago 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 Winnebago County
The Winnebago County Sheriff's Office is the county agency that reports arrests to the FBI for Winnebago County. It reported 590 arrests for 2025.
Arrests inside six 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:
- Oshkosh, 67,242 residents: 3,717 arrests reported for 2025.

- Omro, 3,644 residents: 84 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 Appleton Police Department is listed by the FBI across three counties including Winnebago County, so its arrests are not broken out for Winnebago County here.
The FBI's agency list also places one more agency in Winnebago County: the University of Wisconsin at Oshkosh (campus police).

Booking: Where People Arrested in Winnebago County Are Held
The county jail is where a person arrested in Winnebago 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 250 people, down from about 280 in 2019. Its rated capacity in 2025 was 355 beds, and it ran at 70 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 Winnebago County
An arrest in Winnebago 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 winnebagocountywi.gov/291/District-Attorney).
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 Winnebago 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 Winnebago County Sheriff's Office: ask its records unit.
- An arrest in Oshkosh, Neenah, Fox Crossing, Menasha, Omro or Winneconne: the records unit of the agency that reports for that city; the city guides linked above name each city's records office.
- An arrest by the University of Wisconsin at Oshkosh: the records office of the agency involved.
- A defendant who has been charged gets the report through the case: the District Attorney handles discovery for pending cases.
