Grant County, Wisconsin, has about 52,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from Grant County depends on where the incident happened: the Grant County Sheriff's Office for the unincorporated county, the agency that reports for the city inside a city. This guide names each agency, where its records page is and what the Wisconsin Public Records Law requires of it.
This guide covers which agency, the sheriff's reports, the cities' reports, how many reports, what the law requires and common questions.

Which Agency Holds a Report from Grant County
A crime, incident or collision report belongs to the agency whose officer wrote it, and that agency releases it, not the court, the jail or the prosecutor.
In Grant County that is the Grant County Sheriff's Office for the unincorporated county and for any city that contracts with it for police service, and the agency that reports for a city where the city has one of its own.
The FBI's list also carries the University of Wisconsin at Platteville (campus police), with a records office of its own.

What the Wisconsin Public Records Law Requires
Under the Wisconsin Public Records Law the agency must answer a request 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. The request goes to the agency that holds the report, in writing, and does not have to say why the report is wanted.
Any other county record goes through the county records request page SearchSystems verified, at gcinternetwebsite.co.grant.wi.gov/grant-county-sheriffs-office/publ... (page title: Public Record Requests | Grant County).
A defendant who has been charged gets the report through the case: the District Attorney, (608) 723-4237, handles discovery for pending cases.
