Audrain County, Missouri, has about 24,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Audrain County Sheriff's Office and four 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 Audrain 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 Audrain County
The Audrain County Sheriff's Office is the county agency that reports arrests to the FBI for Audrain County. It reported 157 arrests for 2025.
The FBI lists four cities in Audrain County with a reporting agency of their own, with the Census population and what each reported:
- Mexico, 11,482 residents: 645 arrests reported for 2025.
- Laddonia, 507 residents.
- Martinsburg, 257 residents: 0 arrests reported for 2025.
- Farber, 253 residents: 0 arrests reported for 2021.
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 Audrain 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.
- Mexico: 645 for 2025, 440 for 2021, 589 for 2020 and 530 for 2019; 2022, 2023 and 2024 are missing months.
- Audrain County Sheriff's Office: 157 for 2025, 164 for 2024, 233 for 2023, 226 for 2022, 307 for 2021 and 255 for 2020.
- Martinsburg: 0 for 2025, 0 for 2024 and 0 for 2019; 2020, 2021, 2022 and 2023 are missing months.
- Farber: 0 for 2021 and 0 for 2019; 2020 is missing months.
Together, the three agencies with all twelve months of 2025 on file reported 802 arrests that year. The two of them with both 2025 and 2024 complete reported 157 in 2025 against 164 in 2024, down 4.3 percent.
Through April 2026, the three agencies with every month so far on file reported 224 arrests, against 308 in the same months of 2025.
Laddonia reported only part of 2025 (2 months) and is left out of the totals.
Booking: Where People Arrested in Audrain County Are Held
A person kept in custody after an arrest in Audrain 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 2022 the jail held about 45 people, up from about 36 in 2019. Its rated capacity in 2022 was 140 beds, and it ran at 32 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
SearchSystems opened and checked the custody page of the Audrain County Sheriff's Office at audrainsheriff.com/inmate-lookup (page title: Current Inmate Lookup | Audrain County Sheriff), 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 Audrain County
An arrest in Audrain County can be traced in three places, depending on where the case stands: the custody page of the Audrain County Sheriff's Office described above, for anyone booked into the county jail; the case index of the Audrain County Circuit Court, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at audraincounty.org/circuit-court); the Prosecuting Attorney, which decides whether an arrest becomes a charge (its page is at audraincounty.org/prosecuting-attorney, phone 573-473-5860).
Statewide, Case.net is the Missouri courts' free statewide case search.
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 Audrain 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 Audrain County Sheriff's Office: ask its records unit.
- An arrest in Mexico, Laddonia, Martinsburg or Farber: the records unit of the agency that reports for that city; the city guides linked above name each city's records office.
- A defendant who has been charged gets the report through the case: the Prosecuting Attorney, 573-473-5860, handles discovery for pending cases.
- The court file of a case that was filed: the Audrain County Circuit Court, through the court records page at audraincounty.org/circuit-court.
- Your own statewide record: the same request described above, for your own name.
