Jefferson County, Kansas, has about 18,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Jefferson County Sheriff's Office and eight city agencies. An arrest leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the County Attorney files charges, a case in the Jefferson County District Court. This guide says who keeps each one, what it costs and who may see it.
This guide covers who makes arrests, arrest counts, booking and the jail, finding an arrest, copies, cities and common questions.

Who Makes Arrests in Jefferson County
The Jefferson County Sheriff's Office is the county agency that reports arrests to the FBI for Jefferson County. It reported 260 arrests for 2025.
The FBI lists eight cities in Jefferson County with a reporting agency of their own, with the Census population and what each reported:
- Oskaloosa, 1,073 residents.
- Valley Falls, 1,066 residents: 17 arrests reported for 2021.
- Perry, 846 residents: 3 arrests reported for 2019.
- McLouth, 838 residents: 24 arrests reported for 2022.
- Meriden, 719 residents: 0 arrests reported for 2024.
- Ozawkie, 623 residents: 0 arrests reported for 2019.
- Nortonville, 586 residents: 0 arrests reported for 2025.
- Winchester, 443 residents: 0 arrests reported for 2024.
A city on that list is reported separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
Arrest Counts on File for Jefferson County
The FBI publishes monthly arrest counts on the Crime Data Explorer. For Jefferson County the counts on file are partial: Valley Falls, McLouth, Nortonville, Oskaloosa and five more have sent some months but no full year since 2019, so no annual total is given here.
Booking: Where People Arrested in Jefferson County Are Held
A person kept in custody after an arrest in Jefferson County 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 2021 the jail held about 18 people, down from about 32 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 35 beds, and it ran at 91 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 Jefferson County
Whether someone was arrested in Jefferson County, and what came of it, shows up in two places: Kansas District Court Public Access Portal, the Kansas courts' statewide case search, which shows whether charges were filed; the County Attorney, which decides whether an arrest becomes a charge (its page is at jfcountyks.com/118/County-Attorney, phone (785) 863-2251).
Kansas is one of the states that lets anyone look up another person's statewide criminal history: anyone can order a name-based criminal history record check online, through the Kansas Bureau of Investigation. 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 Jefferson County
An arrest report belongs to the agency whose officer wrote it, and that agency releases it, not the court or the jail. Under the Kansas Open Records Act the agency must answer within 3 business days, and it may charge staff time and copying.
- An arrest by the Jefferson County Sheriff's Office: ask its records unit, reached through the office at 785-863-2765.
- An arrest in Oskaloosa, Valley Falls, Perry, McLouth, Meriden, Ozawkie or another of the cities listed above: the records unit of the agency that reports for that city.
- A defendant who has been charged gets the report through the case: the County Attorney, (785) 863-2251, handles discovery for pending cases.
- Any county record that is not posted: the county records request page SearchSystems verified is at jfcountyks.com/141/Open-Records-Info (page title: Open Records Info | Jefferson County, KS).
- Your own statewide record: the same request described above, for your own name.
