Fallon County, Montana, has about 2,900 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Fallon 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 Fallon County District Court. 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.

One city in Fallon County reports its arrests to the FBI separately:

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 Fallon 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.
- Baker: 14 for 2025, 30 for 2024, 27 for 2023, 26 for 2022, 26 for 2021 and 11 for 2020.

Together, the two agencies with all twelve months of 2025 on file reported 17 arrests that year. The same agencies with both 2025 and 2024 complete reported 17 in 2025 against 44 in 2024, down 61 percent.
Through August 2026, the two agencies with every month so far on file reported 18 arrests, against 11 in the same months of 2025.
Booking: Where People Arrested in Fallon County Are Held
A person kept in custody after an arrest in Fallon County 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 2019 the jail held about 3 people. Its rated capacity in 2019 was 10 beds, and it ran at 29 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 Fallon County
Whether someone was arrested in Fallon County, and what came of it, shows up in two places: the case index of the Fallon County District Court, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at courts.mt.gov); the County Attorney, which decides whether an arrest becomes a charge (its page is at falloncountymt.gov/county-attorney).
Montana is one of the states that lets anyone look up another person's statewide criminal history: the CHOPRS service lets anyone search public criminal history online by name, through the Montana Department of Justice. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
Getting a Copy of an Arrest Record in Fallon 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 Montana Public Records Act the agency must answer in a timely manner; the statute sets no number of days, and it may charge the actual cost of fulfilling the request.
- An arrest by the Fallon County Sheriff's Office: ask its records unit, reached through the office at 800-943-2189.
- An arrest in Baker: 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 handles discovery for pending cases.
- The court file of a case that was filed: the Fallon County District Court, through the court records page at courts.mt.gov.
- Your own statewide record: the same request described above, for your own name.
