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 Lake Geneva
The Walworth County Sheriff's Office and the agency that reports for Lake Geneva (filed by the FBI as Lake Geneva Police Department) keep the arrest records in and around Lake Geneva: 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.
The FBI's agency list also places one more agency in Walworth County: the University of Wisconsin at Whitewater (campus police); it keeps the records of its own arrests.
The Mukwonago Police Department is listed by the FBI across two counties including Walworth County, so its arrests are not broken out for Walworth County here.
Together, the 14 agencies in Walworth County with all twelve months of 2025 on file reported 4,679 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 Lake Geneva arrest records.

Asking an Agency in Walworth County for a Record
An arrest report, a booking record or a local criminal history letter comes from the agency that holds it, not from the court.
