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 Warrenton
The Warren County Sheriff's Office and the agency that reports for Warrenton (filed by the FBI as Warrenton Police Department) keep the arrest records in and around Warrenton: 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.
The Foristell Police Department is listed by the FBI across two counties including Warren County, so its arrests are not broken out for Warren County here.
Together, the three agencies in Warren County with all twelve months of 2024 on file reported 252 arrests to the FBI that year; how each case ended is in the court file, not in the arresting agency's.
