Maries County, Missouri, has about 8,500 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Maries County Sheriff's Office and one city agency. 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 Maries 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 Maries County
The Maries County Sheriff's Office is the county agency that reports arrests to the FBI for Maries County. It reported 78 arrests for 2025.
One city in Maries County reports its arrests to the FBI separately:
- Vienna, 579 residents: 2 arrests reported for 2025.
A city on that list is reported separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
How Many Arrests Each Agency Reports in Maries County
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.
- Maries County Sheriff's Office: 78 for 2025 and 142 for 2021; 2022, 2023 and 2024 are missing months.
- Vienna: 2 for 2025, 15 for 2021 and 52 for 2019; 2020, 2022, 2023 and 2024 are missing months.
Together, the two agencies with all twelve months of 2025 on file reported 80 arrests that year.
Through May 2026, the two agencies with every month so far on file reported 25 arrests, against 29 in the same months of 2025.
Booking: Where People Arrested in Maries County Are Held
The county jail is where a person arrested in Maries County 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 2018 the jail held about 11 people. The figures are from the Vera Institute of Justice's Incarceration Trends data.
SearchSystems opened and checked the custody page of the Maries County Sheriff's Office at mariescountysheriff.org/inmate-roster/search (page title: Inmate Roster | Maries County Sheriff's Office, MO | Searching | Sort Booking Time | Descending | Page 1), which answered when SearchSystems opened it on September 23, 2026.
That page is the place to look for someone who was booked recently; a person cited and released at the scene, or held only a few hours by a city department, will not be on it.
A sentence of more than a year is served in state prison; the Missouri Department of Corrections lists its inmates at web.mo.gov/doc/offSearchWeb.
How to Find Out About an Arrest in Maries County
An arrest in Maries County can be traced in three places, depending on where the case stands: the custody page of the Maries County Sheriff's Office described above, for anyone booked into the county jail; 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 mariescountymo.gov/prosecuting-attorney-s-office.html, phone 573-422-3396).
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 Maries 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 Maries County Sheriff's Office: ask its records unit.
- An arrest in Vienna: the records unit of the agency that reports for that city.
- A defendant who has been charged gets the report through the case: the Prosecuting Attorney, 573-422-3396, handles discovery for pending cases.
- Your own statewide record: the same request described above, for your own name.
