Boonville, Missouri, in Cooper County, has about 7,900 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 Cooper County Circuit 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 Boonville

How Many Arrests Boonville 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.

Booking: Where People Arrested in Boonville Are Held
A person kept in custody after an arrest in Boonville 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 2021 the jail held about 34 people, down from about 55 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 57 beds, and it ran at 96 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.

Missouri is one of the states that lets anyone look up another person's statewide criminal history: the open record search on the MACHS site lets anyone check convictions by name, through the Missouri State Highway Patrol Criminal Justice Information Services Division. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
