Douglas County, Colorado, has about 394,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from Douglas County depends on where the incident happened: the Douglas 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 Colorado 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 Douglas 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 Douglas County that is the Douglas 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 Aurora Police Department and the Littleton Police Department are each listed by the FBI across several counties including Douglas County, so their arrests are not broken out for Douglas County here.
