Elmore County, Idaho, has about 30,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Elmore 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 Prosecuting Attorney files charges, a case in the Elmore 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.

Who Makes Arrests in Elmore County
The Elmore County Sheriff's Office is the county agency that reports arrests to the FBI for Elmore County. It reported 120 arrests for 2024, its latest complete year.
One city in Elmore County reports its arrests to the FBI separately:
- Mountain Home, 16,912 residents: 560 arrests reported for 2022.
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 Elmore 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.
- Mountain Home: 560 for 2022, 597 for 2020 and 636 for 2019; 2021 is missing months.
- Elmore County Sheriff's Office: 120 for 2024, 104 for 2023, 98 for 2022, 114 for 2021, 169 for 2020 and 241 for 2019.
Together, the two agencies with all twelve months of 2022 on file reported 658 arrests that year. The one of them with both 2022 and 2021 complete reported 98 in 2022 against 114 in 2021, down 14 percent.
Booking: Where People Arrested in Elmore County Are Held
A person kept in custody after an arrest in Elmore 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 2021 the jail held about 51 people, down from about 120 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 127 beds, and it ran at 98 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
A sentence of more than a year is served in state prison; the Idaho Department of Correction lists its inmates at idoc.idaho.gov/content/prisons/resident-client-search.
How to Find Out About an Arrest in Elmore County
An arrest in Elmore County can be traced in two places, depending on where the case stands: the case index of the Elmore County District Court, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at elmorecounty.org/court, phone (208) 587-2130); the Prosecuting Attorney, which decides whether an arrest becomes a charge (its page is at elmorecounty.org/prosecuting-attorney, phone 208.587.2130).
Statewide, iCourt Portal is the Idaho courts' free statewide case search.
Idaho is one of the states that lets anyone look up another person's statewide criminal history: name-based conviction checks are open to the public, through the Idaho State Police Bureau of Criminal Identification. 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 Elmore 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 Idaho Public Records Act the agency must answer within 3 working days, or 10 when more time is needed, and it may charge copying after the first 100 pages and labor after the first two hours.
- An arrest by the Elmore County Sheriff's Office: ask its records unit.
- An arrest in Mountain Home: the records unit of the agency that reports for that city; the city guides linked above name each city's records office.
- A defendant who has been charged gets the report through the case: the Prosecuting Attorney, 208.587.2130, handles discovery for pending cases.
- The court file of a case that was filed: the Elmore County District Court, through the court records page at elmorecounty.org/court, phone (208) 587-2130.
- Your own statewide record: a fingerprint-based request to the Bureau of Criminal Identification.
