Marinette County, Wisconsin, has about 42,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from Marinette County depends on where the incident happened: the Marinette 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.
