Montgomery, Illinois, in Kendall County, has about 22,000 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 State's Attorney files charges, a case in the Circuit Court of Kendall County. 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 Montgomery
The FBI lists Montgomery with an arrest reporting agency of its own, filed as Montgomery Police Department. It reported 220 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 Kendall County Sheriff's Office is the county agency. It reported 335 arrests for 2025.
How Many Arrests Montgomery Reports
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.
- Montgomery: 220 for 2025, 167 for 2024, 132 for 2023, 153 for 2022 and 179 for 2021.
Montgomery's 220 arrests in 2025 were up 32 percent from 167 in 2024.
Through July 2026, Montgomery reported 173 arrests, against 116 in the same months of 2025.
Across Kendall County, the five agencies with all twelve months of 2025 on file reported 1,135 arrests between them.
Booking: Where People Arrested in Montgomery Are Held
The county jail is where a person arrested in Montgomery 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 2021 the jail held about 140 people, down from about 140 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 203 beds, and it ran at 71 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 Montgomery
An arrest in Montgomery can be traced in two places, depending on where the case stands: the case index of the Circuit Court of Kendall County, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at kendallcountyil.gov/offices/circuit-clerk/online-court-records, phone 630-553-4183); the State's Attorney, which decides whether an arrest becomes a charge (its page is at kendallcountyil.gov/offices/state-s-attorney, phone 630-553-4157).
Illinois is one of the states that lets anyone look up another person's statewide criminal history: conviction information is public under the Uniform Conviction Information Act, through the Illinois State Police. 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 Montgomery
An arrest report belongs to the agency whose officer wrote it, and that agency releases it, not the court or the jail. Under the Illinois Freedom of Information Act the agency must answer within 5 business days, with one 5-day extension, and it may charge copying only after the first 50 pages.
