Castle Rock, Colorado, in Douglas County, has about 83,000 residents (2024 Census Bureau estimate), and its arrests are reported to the FBI by an agency of its own. An arrest in the city leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the District Attorney files charges, a case in the Douglas County District Court. This guide says who keeps each one, what it costs and who may see it, with the arrest counts the agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies and common questions.

How Many Arrests Castle Rock Reports
Each agency reports its arrests to the FBI by month, and the FBI publishes them on the Crime Data Explorer. These are the full-year totals, all offenses, as the FBI held them on October 8, 2026; a year with months missing or not reported is left out.
- Castle Rock: 729 for 2025, 1,277 for 2024, 1,250 for 2023, 1,329 for 2022, 1,230 for 2021 and 1,044 for 2020.

Booking: Where People Arrested in Castle Rock Are Held
A person kept in custody after an arrest in Castle Rock is held at the county jail, whichever agency made the arrest, apart from the short stay some city departments' own holding cells allow; a person cited and released at the scene is not booked at all. The jail's record of each person held, with the charges, is a public record of the arrest, and the court file takes over from there.
On an average day in 2025 the jail held about 370 people, up from about 330 in 2019. Its rated capacity in 2025 was 472 beds, and it ran at 77 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.

How to Find Out About an Arrest in Castle Rock
For Castle Rock the place to look is the case index of the Douglas County District Court, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at coloradojudicial.gov/courts/trial-courts/douglas-county, phone 720-437-6114).
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. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
Getting a Copy of an Arrest Record in Castle Rock
The report of an arrest is released by the agency that made it; the jail and the court hold their own records of the same event, but not the report. Under the Colorado Open Records Act the agency must answer 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.
