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 Herculaneum
The Jefferson County Sheriff's Office and the agency that reports for Herculaneum (filed by the FBI as Herculaneum Police Department) keep the arrest records in and around Herculaneum: 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 FBI's agency list also places these agencies in Jefferson County: Jefferson College (campus police); the Dunklin R-5 School District (other agency); each keeps the records of its own arrests.
The Eureka Police Department is listed by the FBI across two counties including Jefferson County, so its arrests are not broken out for Jefferson County here.
Together, the six agencies in Jefferson County with all twelve months of 2025 on file reported 2,576 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 Herculaneum arrest records.
