Quincy, Illinois, in Adams County, has about 39,000 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 Adams 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 Quincy
The FBI lists Quincy with an arrest reporting agency of its own, filed as Quincy Police Department. It reported 0 arrests for 2020, its latest complete year. 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.

The FBI's agency list also places one more agency in Adams County: John Wood Community College (campus police).
How Many Arrests Quincy 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.

Across Adams County, the two agencies with all twelve months of 2025 on file reported 1,389 arrests between them.
Booking: Where People Arrested in Quincy Are Held
The county jail is where a person arrested in Quincy 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 120 people, up from about 120 in 2019. Its rated capacity in 2023 was 194 beds, and it ran at 61 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 Quincy
For Quincy the place to look is the State's Attorney, which decides whether an arrest becomes a charge (its page is at adamscountyil.gov/government/departments/state-s-attorney, phone 217-277-2225).
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 Quincy
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.
