The Wisconsin Criminal History and Your Own Copy
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. The result is the repository record, what agencies reported to the state, which is wider than one county's court index but can lag it.
Arrest Records Kept Locally in Sussex
The Waukesha County Sheriff's Office and the agencies that report for Brookfield (township), Brookfield, Menomonee Falls, New Berlin, Muskego, Oconomowoc and 16 more cities keep the arrest records in and around Sussex: the report and the booking record of each arrest stay with the agency that made it, separate from the court file and from the state repository.
Together, the 16 agencies in Waukesha County with all twelve months of 2025 on file reported 8,658 arrests to the FBI that year; how each case ended is in the court file, not in the arresting agency's.
The agencies and their counts, year by year, are in Sussex arrest records.
