Platte County, Missouri, has about 113,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from Platte County depends on where the incident happened: the Platte 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 Missouri Sunshine Law 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 Platte County
A crime, incident or collision report belongs to the agency whose officer wrote it, and that agency releases it, not the court, the jail or the prosecutor.
In Platte County that is the Platte 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 City International Airport (other agency), with a records office of its own.
The Smithville Police Department and the Kansas City Police Department are each listed by the FBI across several counties including Platte County, so their arrests are not broken out for Platte County here.
