Miami County, Ohio, has about 112,000 residents (2024 Census Bureau estimate). In Ohio the public criminal record is the court file, kept by the Clerk of Courts; the statewide criminal history kept by the Ohio Bureau of Criminal Investigation is released only to its subject and to the employers and agencies the law allows. This guide says where each record of a criminal case from Miami 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, the prosecutor, sex offender registry, records requests and common questions.

Criminal Cases in the Miami County Court of Common Pleas
In Ohio the public criminal record is the court file.

The Ohio Criminal History and Your Own Copy
The statewide criminal history kept by the Ohio Bureau of Criminal Investigation is closed to the public in Ohio: it is released to its subject and to authorized employers and licensing agencies, and a member of the public uses the court's own case index instead.

Arrest Records Kept Locally in Miami County
The Miami County Sheriff's Office and the agencies that report for Troy, Piqua, Tipp City, West Milton and Covington keep the arrest records in Miami 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.
The FBI's agency list also places one more agency in Miami County: the Miami County Park District (other agency); it keeps the records of its own arrests.
The Union Police Department and the Huber Heights Police Department are each listed by the FBI across several counties including Miami County, so their arrests are not broken out for Miami County here.
Together, the four agencies in Miami County with all twelve months of 2025 on file reported 2,105 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 Miami County arrest records.
The Crimes Behind the Records: Miami County in 2025
