Cass County, Nebraska, has about 27,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Cass County Sheriff's Office, one city agency and one state agency. 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 Cass County District Court. This guide says who keeps each one, what it costs and who may see it, with the arrest counts each agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies, cities and common questions.

The Cass County Sheriff's Office is the county agency that reports arrests to the FBI for Cass County. It reported 235 arrests for 2025.
One city in Cass County reports its arrests to the FBI separately:

How Many Arrests Each Agency Reports in Cass County
The FBI publishes every agency's monthly arrest counts 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.
- Cass County Sheriff's Office: 235 for 2025, 338 for 2024, 401 for 2023, 288 for 2022, 273 for 2021 and 277 for 2020.

Booking: Where People Arrested in Cass County Are Held
A person kept in custody after an arrest in Cass 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 2019 the jail held about 84 people. Its rated capacity in 2019 was 114 beds, and it ran at 74 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
SearchSystems opened and checked the custody page of the Cass County Sheriff's Office at casscountysheriffne.gov/inmate-roster/search (page title: Inmate Roster | Cass County NE Sheriff's Office | Searching | Sort Booking Time | Descending | Page 1), phone 800.527.3699, which answered when SearchSystems opened it on September 24, 2026.
That page is the place to look for someone who was booked recently; a person cited and released at the scene, or held only a few hours by a city department, will not be on it.
A sentence of more than a year is served in state prison; the Nebraska Department of Correctional Services lists its inmates at dcs-inmatesearch.ne.gov/Corrections/COR_input.jsp.
How to Find Out About an Arrest in Cass County
An arrest in Cass County can be traced in three places, depending on where the case stands: the custody page of the Cass County Sheriff's Office described above, for anyone booked into the county jail; the case index of the Cass County District Court, kept by the Clerk of the District Court, which shows whether charges were filed and the next court date; the County Attorney, which decides whether an arrest becomes a charge (its page is at casscountyne.gov/county-attorney, phone 402-296-9346).
The court records page SearchSystems verified for the county, at nebraskajudicial.gov/courts/cass-county-court (page title: Cass County Court | Nebraska Judicial Branch), phone 402-296-9334, belongs to a lower court, not to the Cass County District Court.
Statewide, Nebraska Trial Court Case Search is the Nebraska Judicial Branch's statewide case search, with a fee per search.
Nebraska is one of the states that lets anyone look up another person's statewide criminal history: the Patrol sells name-based criminal history checks to anyone online, through the Nebraska State Patrol. 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 Cass County
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 Nebraska Public Records Statutes the agency must answer within 4 business days, and it may charge copying, and staff time after the first four hours.
