Middleton, Idaho, in Canyon County, has about 12,000 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 Prosecuting Attorney files charges, a case in the Canyon County District Court. 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 Middleton
The FBI lists Middleton with an arrest reporting agency of its own, filed as Middleton Police Department. It reported 190 arrests for 2025. A city is listed separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
Outside the city, the Canyon County Sheriff's Office is the county agency. It reported 1,177 arrests for 2025.
How Many Arrests Middleton Reports
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.
- Middleton: 190 for 2025, 170 for 2024, 206 for 2023, 104 for 2022, 98 for 2021 and 52 for 2020.
Middleton's 190 arrests in 2025 were up 12 percent from 170 in 2024.
Through May 2026, Middleton reported 59 arrests, against 72 in the same months of 2025.
Across Canyon County, the five agencies with all twelve months of 2025 on file reported 4,145 arrests between them.
Booking: Where People Arrested in Middleton Are Held
A person kept in custody after an arrest in Middleton 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 2023 the jail held about 430 people, up from about 420 in 2019. Its rated capacity in 2023 was 525 beds, and it ran at 82 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 Canyon County Sheriff's Office at jailroster.canyoncounty.id.gov (page title: Jail Roster), phone (208) 454-7541, which answered when SearchSystems opened it on September 30, 2026.
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.

How to Find Out About an Arrest in Middleton
Whether someone was arrested in Middleton, and what came of it, shows up in three places: the custody page of the Canyon County Sheriff's Office described above, for anyone booked into the county jail; the case index of the Canyon County District Court, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at canyoncounty.id.gov/court-records-request, phone 208-454-7495); the Prosecuting Attorney, which decides whether an arrest becomes a charge (its page is at canyoncounty.id.gov/elected-officials/prosecuting-attorney, phone 208-454-7391).

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 Middleton
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.
