The Iowa Criminal History and Your Own Copy
Iowa is one of the states that lets anyone look up another person's statewide criminal history: anyone can request a name-based criminal history check online, through the Iowa Division of Criminal Investigation. 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 Marshall County
The Marshall County Sheriff's Office and the agencies that report for Marshalltown and State Center keep the arrest records in Marshall 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.
Marshalltown reported 902 arrests to the FBI for 2025; how each case ended is in the court file, not in the arresting agency's.
