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.
