Dallas County, Missouri, has about 18,000 residents (2024 Census Bureau estimate). In Missouri the public criminal record is the court file, kept by the Circuit Clerk; the statewide criminal history kept by the Missouri State Highway Patrol Criminal Justice Information Services Division is open to anyone who asks. This guide says where each record of a criminal case from Dallas County is kept and how it is seen.
This guide covers the court file, the statewide record, local arrest records, the crimes behind the records, sex offender registry, records requests, directory links and common questions.

Criminal Cases in the Dallas County Circuit Court
A criminal case from Dallas County is filed in the Dallas County Circuit Court, and the court file, kept by the Circuit Clerk, is the record of it that the public may see.
The court records page SearchSystems verified for the county is at courts.mo.gov/page.jsp?id=4835 (page title: Dallas County Local Rules & Filing Information), a site that blocks automated checks (HTTP 403), so open it in a browser.

The Missouri Criminal History and Your Own Copy
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. The result is the repository record, what agencies reported to the state, which is wider than one county's court index but can lag it.
Arrest Records Kept Locally in Dallas County
The Dallas County Sheriff's Office and the agency that reports for Buffalo keep the arrest records in Dallas County: the report and the booking record of each arrest stay with the agency that made it, separate from the court file and from the state repository.
Together, the two agencies in Dallas County with all twelve months of 2025 on file reported 6 arrests to the FBI that year; how each case ended is in the court file, not in the arresting agency's.
The agencies and their counts, year by year, are in Dallas County arrest records.
The Crimes Behind the Records: Dallas County in 2023
The two agencies in Dallas County with all twelve months of 2023 on file reported 21 violent and 108 property crimes to the FBI that year; the same agencies with both 2023 and 2022 complete reported 129 crimes in 2023 against 192 in 2022. Each reported crime is a report on file with the agency that took it, and each arrest that follows is the start of a criminal record.

The Sex Offender Registry for Dallas County
Registered sex offenders living in Dallas County are listed on the Missouri Sex Offender Registry, run by the Missouri State Highway Patrol at mshp.dps.missouri.gov/CJ38/searchRegistry.jsp. The registry is public and can be searched online.
Registration itself is done in person with the local agency where the registrant lives: the sheriff's office, or the city police in a city with its own department.
Asking an Agency in Dallas County for a Record
An arrest report, a booking record or a local criminal history letter comes from the agency that holds it, not from the court.
Under the Missouri Sunshine Law a county office must answer a request within 3 business days, and it may charge research time and copying.
