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 Hermiston
The Umatilla County Sheriff's Office and the agency that reports for Hermiston (filed by the FBI as Hermiston Police Department) keep the arrest records in and around Hermiston: 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 Umatilla County: the Umatilla County Liquor Commission (state agency); the Umatilla County State Police (state police); each keeps the records of its own arrests.
Together, the five agencies in Umatilla County with all twelve months of 2025 on file reported 3,235 arrests to the FBI that year; how each case ended is in the court file, not in the arresting agency's.
