Reviewed and updated October 9, 2026 by the SearchSystems.net editorial team. The arrest counts are the ones each agency reported to the FBI, as the FBI held them on October 8, 2026. The jail figures are from the Vera Institute of Justice's Incarceration Trends data.
Montgomery County, Missouri, has about 12,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Montgomery County Sheriff's Office and six city agencies. An arrest 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 Montgomery County Circuit Court. This guide says who keeps each one, what it costs and who may see it, with the arrest counts each agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies, cities and common questions.

Who Makes Arrests in Montgomery County
The Montgomery County Sheriff's Office is the county agency that reports arrests to the FBI for Montgomery County. It reported 258 arrests for 2025.
The FBI lists six cities in Montgomery County with a reporting agency of their own, with the Census population and what each reported:

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.

Booking: Where People Arrested in Montgomery County Are Held
A person kept in custody after an arrest in Montgomery County 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 2019 the jail held about 65 people. Its rated capacity in 2019 was 110 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 person sentenced to prison serves the sentence in a facility of the Missouri Department of Corrections, whose inmate locator is at web.mo.gov/doc/offSearchWeb.
How to Find Out About an Arrest in Montgomery County
For Montgomery County the place to look is Case.net, the Missouri courts' free statewide case search, which shows whether charges were filed.
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 Montgomery County
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 Montgomery County Sheriff's Office: ask its records unit.
- An arrest in Montgomery City, Wellsville, Jonesburg, New Florence, Bellflower or High Hill: the records unit of the agency that reports for that city.
- Your own statewide record: the same request described above, for your own name.
