The Kansas Criminal History and Your Own Copy
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. 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 Colby
The Thomas County Sheriff's Office and the agency that reports for Colby (filed by the FBI as Colby Police Department) keep the arrest records in and around Colby: 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 Oakley Police Department is listed by the FBI across three counties including Thomas County, so its arrests are not broken out for Thomas County here.
