Cassia County, Idaho, has about 26,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Cassia County Sheriff's Office.

This guide says who keeps each one, what it costs and who may see it, with the arrest counts each agency reported.

The county jail is where a person arrested in Cassia 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.

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.

An arrest report belongs to the agency whose officer wrote it, and that agency releases it, not the court or the jail. 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.
