Platte County, Wyoming, has about 8,500 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Platte County Sheriff's Office and two city agencies. An arrest leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the County Attorney files charges, a case in the District Court for Platte County. This guide says who keeps each one, what it costs and who may see it, with the arrest counts each agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies, cities and common questions.

Who Makes Arrests in Platte County
The Platte County Sheriff's Office is the county agency that reports arrests to the FBI for Platte County. It reported 111 arrests for 2020, its latest complete year.
The FBI lists two cities in Platte County with a reporting agency of their own, with the Census population and what each reported:
- Wheatland, 3,475 residents: 207 arrests reported for 2020.
- Guernsey, 1,094 residents: 1,152 arrests reported for 2025.
A city on that list is reported separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
How Many Arrests Guernsey Reports
Each agency reports its arrests to the FBI by month, and the FBI publishes them on the Crime Data Explorer. These are the full-year totals, all offenses, as the FBI held them on October 8, 2026; a year with months missing or not reported is left out.
- Guernsey: 1,152 for 2025, 1,152 for 2024, 1,146 for 2023, 1,132 for 2022, 919 for 2021 and 1,146 for 2020.
- Wheatland: 207 for 2020 and 238 for 2019.
- Platte County Sheriff's Office: 111 for 2020 and 144 for 2019.
Guernsey's 1,146 arrests in 2023 were up 1.2 percent from 1,132 in 2022.
Booking: Where People Arrested in Platte County Are Held
The county jail is where a person arrested in Platte County and kept in custody ends up, whichever agency made the arrest, though a city department may hold someone in its own cells first and a person cited and released at the scene is never booked. The jail's record of each person held, with the charges, is a public record of the arrest, and once the person is released or sentenced the record continues in the court file.
On an average day in 2019 the jail held about 75 people. Its rated capacity in 2019 was 95 beds, and it ran at 79 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.

How to Find Out About an Arrest in Platte County
For Platte County the place to look is the case index of the District Court for Platte County, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at wyocomet.wyo.gov/repositories/2/resources/943, phone (307) 777-7826).
Wyoming does not let the public search another person's statewide criminal history. The record kept by the Wyoming Division of Criminal Investigation goes to the person it belongs to and to employers and agencies the law authorizes; for everyone else the court's own case index is the public record of an arrest that led to a charge.
Getting a Copy of an Arrest Record in Platte County
The report of an arrest is released by the agency that made it; the jail and the court hold their own records of the same event, but not the report. Under the Wyoming Public Records Act the agency must answer within 30 days at most, and it may charge the actual cost of copying.
