Booking: Where People Arrested in Belvidere Are Held

The county jail is where a person arrested in Belvidere 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 2023 the jail held about 46 people, down from about 89 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 150 beds, and it ran at 59 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 Illinois Department of Corrections lists its inmates at idoc.illinois.gov/offender/inmatesearch.html.

How to Find Out About an Arrest in Belvidere

An arrest in Belvidere can be traced in two places, depending on where the case stands: the case index of the Circuit Court of Boone County, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at boonecircuitclerk.us/page/11/court-records, phone 815-544-0371); the State's Attorney, which decides whether an arrest becomes a charge (its page is at boonecountyil.gov/government/departments/state_s_attorney/index.php, phone 815.544.0868).

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.
