Cornelius, Oregon, in Washington County, has about 15,000 residents (2024 Census Bureau estimate), and its arrests are reported to the FBI by an agency of its own. An arrest in the city leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the District Attorney files charges, a case in the Washington County Circuit Court. This guide says who keeps each one, what it costs and who may see it, with the arrest counts the agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies and common questions.

Who Makes Arrests in Cornelius
The FBI lists Cornelius with an arrest reporting agency of its own, filed as Cornelius Police Department. It reported 557 arrests for 2025. A city is listed separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
Outside the city, the Washington County Sheriff's Office is the county agency. It reported 6,159 arrests for 2025.
The FBI's agency list also places these agencies in Washington County: the Washington County Liquor Commission (state agency); the Hillsboro School District (other); the Washington County State Police (state police).
How Many Arrests Cornelius Reports
Each agency reports its arrests to the FBI by month, and the FBI publishes them on the Crime Data Explorer. These are the full-year totals, all offenses, as the FBI held them on October 8, 2026; a year with months missing or not reported is left out.
- Cornelius: 557 for 2025, 701 for 2024, 499 for 2023, 449 for 2022, 412 for 2021 and 397 for 2020.
Cornelius's 557 arrests in 2025 were down 21 percent from 701 in 2024.
Through August 2026, Cornelius reported 339 arrests, against 353 in the same months of 2025.
Across Washington County, the 12 agencies with all twelve months of 2025 on file reported 18,060 arrests between them.
Booking: Where People Arrested in Cornelius Are Held
A person kept in custody after an arrest in Cornelius is held at the county jail, whichever agency made the arrest, apart from the short stay some city departments' own holding cells allow; a person cited and released at the scene is not booked at all. The jail's record of each person held, with the charges, is a public record of the arrest, and the court file takes over from there.
On an average day in 2023 the jail held about 420 people, down from about 560 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 572 beds, and it ran at 98 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.

How to Find Out About an Arrest in Cornelius
Whether someone was arrested in Cornelius, and what came of it, shows up in two places: the case index of the Washington County Circuit Court, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at courts.oregon.gov/courts/washington/records/pages/default.aspx); the District Attorney, which decides whether an arrest becomes a charge (its page is at washingtoncountyor.gov/locations/justice-services-building/district...).
Statewide, Oregon eCourt Case Information is the Oregon Judicial Department's online case search, free for basic case information.
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. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
Getting a Copy of an Arrest Record in Cornelius
The report of an arrest is released by the agency that made it; the jail and the court hold their own records of the same event, but not the report. Under the Oregon Public Records Law the agency must answer within 15 business days where practicable, after acknowledging the request within 5, and it may charge the actual cost of making the record available.
