Greenfield, Wisconsin, in Milwaukee County, has about 37,000 residents (2024 Census Bureau estimate), and its arrests are reported to the FBI by an agency of its own. An arrest in the city 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 Milwaukee County Circuit Court. This guide says who keeps each one, what it costs and who may see it, with the arrest counts the agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies and common questions.

Who Makes Arrests in Greenfield
The FBI lists Greenfield with an arrest reporting agency of its own, filed as Greenfield Police Department. It reported 1,413 arrests for 2025. A city is listed separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
Outside the city, the Milwaukee County Sheriff's Office is the county agency. It reported 2,392 arrests for 2025.
The FBI's agency list also places these agencies in Milwaukee County: the University of Wisconsin at Milwaukee and Marquette University (campus police); the State Fair Park Police (state agency).
How Many Arrests Greenfield Reports
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.
- Greenfield: 1,413 for 2025, 1,205 for 2024, 1,465 for 2023, 1,190 for 2022, 910 for 2021 and 785 for 2020.
Greenfield's 1,413 arrests in 2025 were up 17 percent from 1,205 in 2024.
Across Milwaukee County, the 20 agencies with all twelve months of 2025 on file reported 28,168 arrests between them.
Booking: Where People Arrested in Greenfield Are Held
A person kept in custody after an arrest in Greenfield 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 2025 the jail held about 2,170 people, up from about 1,930 in 2019. Its rated capacity in 2025 was 2,738 beds, and it ran at 79 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
SearchSystems opened and checked the custody page of the Milwaukee County Sheriff's Office at incustodysearch.milwaukeecountywi.gov (page title: Milwaukee County Sheriff | In Custody Locator), which answered when SearchSystems opened it on September 23, 2026.
That page is the place to look for someone who was booked recently; a person cited and released at the scene, or held only a few hours by a city department, will not be on it.
A sentence of more than a year is served in state prison; the Wisconsin Department of Corrections lists its inmates at appsdoc.wi.gov/lop/welcome.
How to Find Out About an Arrest in Greenfield
Whether someone was arrested in Greenfield, and what came of it, shows up in two places: the custody page of the Milwaukee County Sheriff's Office described above, for anyone booked into the county jail; the case index of the Milwaukee County Circuit Court, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at wicourts.gov/casesearch.htm).
Statewide, Wisconsin Circuit Court Access is the free statewide case search of every circuit court.
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 Greenfield
An arrest report belongs to the agency whose officer wrote it, and that agency releases it, not the court or the jail. 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.
