Dallas County, Missouri, has about 18,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Dallas 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 Dallas 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.

How Many Arrests Each Agency Reports in Dallas County
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.
- Buffalo: 6 for 2025, 23 for 2024, 16 for 2023, 32 for 2022 and 99 for 2019; 2020 and 2021 are missing months.

Booking: Where People Arrested in Dallas County Are Held
The county jail is where a person arrested in Dallas 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 2019 the jail held about 25 people. Its rated capacity in 2019 was 34 beds, and it ran at 74 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.

How to Find Out About an Arrest in Dallas County
For Dallas 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 Dallas 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 Dallas County Sheriff's Office: ask its records unit.
- An arrest in Buffalo: the records unit of the agency that reports for that city.
