Marion County, Missouri, has about 28,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from Marion County depends on where the incident happened: the Marion 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 Marion 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 Marion County that is the Marion 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 Monroe City Police Department is listed by the FBI across three counties including Marion County, so its arrests are not broken out for Marion County here.
