Sumner County, Kansas, has about 22,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from Sumner County depends on where the incident happened: the Sumner County Sheriff's Office for the unincorporated county, the agency that reports for the city inside a city. This guide names each agency, where its records page is and what the Kansas Open Records Act requires of it.
This guide covers which agency, the sheriff's reports, the cities' reports, how many reports, what the law requires and common questions.

Which Agency Holds a Report from Sumner County
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.
In Sumner County that is the Sumner County Sheriff's Office for the unincorporated county and for any city that contracts with it for police service, and the agency that reports for a city where the city has one of its own.
The FBI's list also carries Kansas Racing and Gaming Commission Law Enforcement (state agency), with a records office of its own.
The Mulvane Police Department is listed by the FBI across two counties including Sumner County, so its arrests are not broken out for Sumner 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 co.sumner.ks.us/elected_officials/county_clerk_and_election_officer... (page title: Sumner County, KS).
A defendant who has been charged gets the report through the case: the County Attorney, (620)326-7941, handles discovery for pending cases.
