Colorado has no single public index of every trial court case; each court's records are looked up through that court.
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....

The Sex Offender Registry for Douglas County

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.

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).
