Hannibal, Missouri, in Marion County, has about 17,000 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 Marion 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 Hannibal
The FBI lists Hannibal with an arrest reporting agency of its own, filed as Hannibal Police Department. It reported 573 arrests for 2024, 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.
Outside the city, the Marion County Sheriff's Office is the county agency. It reported 13 arrests for 2025.
How Many Arrests Hannibal 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.
- Hannibal: 573 for 2024, 552 for 2023, 753 for 2022, 1,015 for 2021, 3,011 for 2020 and 3,952 for 2019.
Hannibal's 573 arrests in 2024 were up 3.8 percent from 552 in 2023.
Across Marion County, the two agencies with all twelve months of 2024 on file reported 580 arrests between them.
Booking: Where People Arrested in Hannibal Are Held
The county jail is where a person arrested in Hannibal 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 86 people, down from about 92 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 90 beds, and it ran at 102 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
SearchSystems opened and checked the jail page of the Marion County Sheriff's Office at marioncounty-mo.gov/departments/sheriff (page title: Marion County Sheriff | Marion County, Missouri), phone (573) 769-2077, Monday through Friday. 8:00 a.m. to 4:00 p.m., which answered when SearchSystems opened it on September 30, 2026.

How to Find Out About an Arrest in Hannibal
Whether someone was arrested in Hannibal, and what came of it, shows up in two places: Case.net, the Missouri courts' free statewide case search, which shows whether charges were filed; the Prosecuting Attorney, which decides whether an arrest becomes a charge (its page is at marioncounty-mo.gov/departments/prosecuting-attorney, phone (573) 221-0146).
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.
Getting a Copy of an Arrest Record in Hannibal
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 Missouri Sunshine Law the agency must answer within 3 business days, and it may charge research time and copying.
- An arrest by the agency that reports for Hannibal: its own records unit.
- An arrest by the Marion County Sheriff's Office: ask its records unit, reached through the office at (573) 769-2077.
- A defendant who has been charged gets the report through the case: the Prosecuting Attorney, (573) 221-0146, handles discovery for pending cases.
- Your own statewide record: the same request described above, for your own name.
