Big Horn County, Wyoming, has about 12,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Big Horn County Sheriff's Office and three 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 Big Horn 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 Big Horn County
The Big Horn County Sheriff's Office is the county agency that reports arrests to the FBI for Big Horn County. It reported 52 arrests for 2025.
The FBI lists three cities in Big Horn County with a reporting agency of their own, with the Census population and what each reported:
- Lovell, 2,366 residents: 1,152 arrests reported for 2025.
- Greybull, 1,715 residents: 29 arrests reported for 2020.
- Basin, 1,337 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 Each Agency Reports in Big Horn County
The FBI publishes every agency's monthly arrest counts 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.

Booking: Where People Arrested in Big Horn County Are Held
The county jail is where a person arrested in Big Horn 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 2022 the jail held about 50 people, down from about 85 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 90 beds, and it ran at 94 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
SearchSystems opened and checked the custody page of the Big Horn County Sheriff's Office at bighorncountywysheriff.com/inmate-search (page title: Big Horn County Inmate Search, Jail Rosters), a site that blocks automated checks (HTTP 403), so open it in a browser.
That page is the place to look for someone who was booked recently; a person cited and released at the scene, or held only a few hours by a city department, will not be on it.
A sentence of more than a year is served in state prison; the Wyoming Department of Corrections lists its inmates at wdoc-loc.wyo.gov.
How to Find Out About an Arrest in Big Horn County
An arrest in Big Horn County can be traced in three places, depending on where the case stands: the custody page of the Big Horn County Sheriff's Office described above, for anyone booked into the county jail; the case index of the District Court for Big Horn 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/961, phone (307) 777-7826); the County Attorney, which decides whether an arrest becomes a charge (its page is at bighorncountywy.gov/departments/attorney, phone (307) 568-2436).
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 Big Horn County
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.
- An arrest by the Big Horn County Sheriff's Office: ask its records unit.
- An arrest in Lovell, Greybull or Basin: the records unit of the agency that reports for that city.
- A defendant who has been charged gets the report through the case: the County Attorney, (307) 568-2436, handles discovery for pending cases.
- The court file of a case that was filed: the District Court for Big Horn County, through the court records page at wyocomet.wyo.gov/repositories/2/resources/961, phone (307) 777-7826.
- Your own statewide record: a fingerprint-based request to the Division of Criminal Investigation.
