Gillette, Wyoming, in Campbell County, has about 34,000 residents (2024 Census Bureau estimate), and its arrests are reported to the FBI by an agency of its own. An arrest in the city 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 Campbell County. This guide says who keeps each one, what it costs and who may see it, with the arrest counts the agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies and common questions.

Who Makes Arrests in Gillette

Outside the city, the Campbell County Sheriff's Office is the county agency. It reported 379 arrests for 2025.
How Many Arrests Gillette 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.
- Gillette: 1,717 for 2025, 1,790 for 2024, 1,956 for 2023, 2,066 for 2022, 1,939 for 2021 and 2,602 for 2020.

Booking: Where People Arrested in Gillette Are Held
A person kept in custody after an arrest in Gillette is held at the county jail, whichever agency made the arrest, apart from the short stay some city departments' own holding cells allow; a person cited and released at the scene is not booked at all. The jail's record of each person held, with the charges, is a public record of the arrest, and the court file takes over from there.
On an average day in 2018 the jail held about 200 people. The figures are from the Vera Institute of Justice's Incarceration Trends data.

How to Find Out About an Arrest in Gillette
For Gillette the place to look is the County Attorney, which decides whether an arrest becomes a charge (its page is at campbellcountywy.gov/135/County-Attorney, phone (307) 682-4310).
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 Gillette
An arrest report belongs to the agency whose officer wrote it, and that agency releases it, not the court or the jail. Under the Wyoming Public Records Act the agency must answer within 30 days at most, and it may charge the actual cost of copying.
