The Oregon Criminal History and Your Own Copy
Oregon is one of the states that lets anyone look up another person's statewide criminal history: an Open Record Request returns anyone's Oregon conviction record by name, and the subject is told who asked, for $10 a search, through the Oregon State Police. 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. The search is on the Oregon State Police site.
Arrest Records Kept Locally in Marion County
The Marion County Sheriff's Office and the agencies that report for Salem, Keizer, Woodburn, Silverton, Stayton, Aumsville and four more cities keep the arrest records in Marion 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 these agencies in Marion County: the Marion County State Police (state police); the Marion County Liquor Commission (state agency); each keeps the records of its own arrests.
Together, the seven agencies in Marion County with all twelve months of 2025 on file reported 8,301 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 Marion County arrest records.

Asking an Agency in Marion 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 Oregon Public Records Law a county office must answer a request within 15 business days where practicable, after acknowledging the request within 5, and it may charge the actual cost of making the record available. The county records request page SearchSystems verified is at co.marion.or.us/BOC/Pages/Public-Records-Requests.aspx (page title: Public Records Requests).
