Harrison County, Ohio, has about 14,000 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 Harrison 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 Harrison County Court of Common Pleas
A criminal case from Harrison County is filed in the Harrison County Court of Common Pleas or the Municipal and County Courts, which take misdemeanors, traffic cases, evictions and civil cases up to $15,000; mayor's courts handle some village tickets, and the court file, kept by the Clerk of Courts, is the record of it that the public may see.
The court records page SearchSystems verified for the county is at harrisoncountyohio.gov/court (page title: Harrison County Court), phone 740-942-8865, Monday - Friday 8:00 a.m. - 4:30 p.m., which answered when SearchSystems opened it on September 23, 2026. That page belongs to a lower court, the Municipal and County Courts, not to the Harrison County Court of Common Pleas.
Ohio has no single public index of every trial court case; each court's records are looked up through that court.
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.
To see your own record, the route is a fingerprint-based WebCheck at any WebCheck location. The state page SearchSystems verified for it is at ohioattorneygeneral.gov/Individuals-and-Families/Consumers/Requesti....

The Adena Police Department is listed by the FBI across two counties including Harrison County, so its arrests are not broken out for Harrison County here.
Together, the two agencies in Harrison County with all twelve months of 2025 on file reported 112 arrests to the FBI that year; how each case ended is in the court file, not in the arresting agency's.

The Prosecuting Attorney for Harrison County

Asking an Agency in Harrison County for a Record
An arrest report, a booking record or a local criminal history letter comes from the agency that holds it, not from the court.
Under the Ohio Public Records Act a county office must answer a request promptly, within a reasonable period of time, and it may charge the actual cost of copying. The county records request page SearchSystems verified is at harrisoncountyohio.gov/public-records-request (page title: Public Records Request).
