Crook County, Wyoming, has about 7,800 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Crook County Sheriff's Office and one city agency. 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 Crook 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 Crook County
The Crook County Sheriff's Office is the county agency that reports arrests to the FBI for Crook County. It reported 49 arrests for 2025.
The FBI lists one city in Crook County with a reporting agency of its own:
- Moorcroft, 1,025 residents: 15 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 Each Agency Reports in Crook County
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.
- Crook County Sheriff's Office: 49 for 2025, 97 for 2023, 157 for 2021, 144 for 2020 and 204 for 2019; 2022 and 2024 are missing months.
- Moorcroft: 15 for 2025, 18 for 2024, 46 for 2023, 30 for 2022, 21 for 2021 and 59 for 2020.
Together, the two agencies with all twelve months of 2025 on file reported 64 arrests that year. The one of them with both 2025 and 2024 complete reported 15 in 2025 against 18 in 2024.
Through July 2026, the two agencies with every month so far on file reported 45 arrests, against 37 in the same months of 2025.
Booking: Where People Arrested in Crook County Are Held
The county jail is where a person arrested in Crook 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 2024 the jail held about 6 people, down from about 10 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 30 beds, and it ran at 33 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 Crook County
Whether someone was arrested in Crook County, and what came of it, shows up in two places: the case index of the District Court for Crook County, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at crookcounty.wy.gov/new_elected_officials/clerk_of_district_court/in..., phone (307) 283-2523); the County Attorney, which decides whether an arrest becomes a charge (its page is at crookcounty.wy.gov/elected_officials/attorney/index.php, phone (307) 283-1090).
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 Crook 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.
