The Nebraska Criminal History and Your Own Copy
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. 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.
Arrest Records Kept Locally in South Sioux City
The Dakota County Sheriff's Office and the agency that reports for South Sioux City (filed by the FBI as South Sioux City Police Department) keep the arrest records in and around South Sioux City: 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 one more agency in Dakota County: the State Patrol in Dakota County (state police); it keeps the records of its own arrests.
The Emerson Police Department is listed by the FBI across three counties including Dakota County, so its arrests are not broken out for Dakota County here.
