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 Leavenworth County
