Which Agency Holds a Report from Derby
The report of an incident is released by the agency that took it; the court and the jail hold their own records of the same event, but not the report.
Inside Derby that is the agency that reports to the FBI for the city (filed by the FBI as Derby Police Department); outside it, the Sedgwick County Sheriff's Office.
The FBI's agency list also places one campus police department, two other agencies and one state agency in Sedgwick County, each with a records office of its own.
The Sedgwick Police Department is listed by the FBI across two counties including Sedgwick County, so its arrests are not broken out for Sedgwick County here.

What the Kansas Open Records Act Requires
Under the Kansas Open Records Act the agency must answer a request within 3 business days, and it may charge staff time and copying. The request goes to the agency that holds the report, in writing, and does not have to say why the report is wanted.
Any other county record goes through the county records request page SearchSystems verified, at sedgwickcounty.org/fire/forms/records-request (page title: Records Request | Sedgwick County, Kansas).
A defendant who has been charged gets the report through the case: the County Attorney handles discovery for pending cases.
