The Colorado Criminal History and Your Own Copy
Colorado is one of the states that lets anyone look up another person's statewide criminal history: the state runs an online name-based criminal history check open to the public, through the Colorado Bureau of Investigation. The result is the repository record, what agencies reported to the state, which is wider than one county's court index but can lag it.
To see your own record, the route is a name-based or fingerprint-based request to the Colorado Bureau of Investigation. The state page SearchSystems verified for it is at cbi.colorado.gov/records-background-checks/internet-criminal-histor....
Arrest Records Kept Locally in Castle Rock
The Douglas County Sheriff's Office and the agency that reports for Castle Rock (filed by the FBI as Castle Rock Police Department) keep the arrest records in and around Castle Rock: the report and the booking record of each arrest stay with the agency that made it, separate from the court file and from the state repository.
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.
Together, the four agencies in Douglas County with all twelve months of 2025 on file reported 5,515 arrests to the FBI that year; how each case ended is in the court file, not in the arresting agency's.
The agencies and their counts, year by year, are in Castle Rock arrest records.
The Crimes Behind the Records: Castle Rock in 2025
The agency that reports for Castle Rock had 26 violent and 808 property crimes reported for 2025; each one is a report on file with it, and each arrest that follows is the start of a criminal record.
The Sex Offender Registry for Castle Rock
Registered sex offenders living in Castle Rock are listed on the Colorado Sex Offender Registry, run by the Colorado Bureau of Investigation at apps.colorado.gov/apps/dps/sor. Only sexually violent predators, multiple offenders and adults convicted of felony sex offenses appear on the statewide site; local police and sheriffs hold the full list.
Registration itself is done in person with the local agency where the registrant lives: the sheriff's office, or the city police in a city with its own department.
Asking an Agency in Douglas County for a Record
An arrest report, a booking record or a local criminal history letter comes from the agency that holds it, not from the court.
Under the Colorado Open Records Act a county office must answer a request within 3 working days, extendable to 7 when there are extenuating circumstances, and it may charge research and retrieval time after the first hour, plus copying. The county records request page SearchSystems verified is at douglasco.gov/board-county-commissioners/transparency/open-records (page title: Colorado Open Records Act (CORA) | Douglas County).
