Natrona County, Wyoming, has about 80,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from Natrona County depends on where the incident happened: the Natrona 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 Wyoming Public Records Act 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.
