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....
Arrest Records Kept Locally in Lafayette
The Boulder County Sheriff's Office and the agency that reports for Lafayette (filed by the FBI as Lafayette Police Department) keep the arrest records in and around Lafayette: 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 FBI's agency list also places these agencies in Boulder County: Colorado Department of Revenue in Marijuana Enforcement Criminal Investigation, Boulder County (state agency); the University of Colorado at Boulder (campus police); each keeps the records of its own arrests.
The Erie Police Department is listed by the FBI across two counties including Boulder County, so its arrests are not broken out for Boulder County here.
Together, the five agencies in Boulder County with all twelve months of 2025 on file reported 7,765 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 Lafayette arrest records.

Asking an Agency in Boulder 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.
