Platte County, Wyoming, has about 8,500 residents (2024 Census Bureau estimate). In Wyoming the public criminal record is the court file, kept by the Clerk of District Court; the statewide criminal history kept by the Wyoming Division of Criminal Investigation is released only to its subject and to the employers and agencies the law allows. This guide says where each record of a criminal case from Platte County is kept and how it is seen.

To see your own record, the route is a fingerprint-based request to the Division of Criminal Investigation. The state page SearchSystems verified for it is at wyomingdci.wyo.gov/criminal-justice-information-services-cjis/crimi....
