Investigations

Commander Doug Ernst oversees the Investigations Division, which investigates all crimes, including misdemeanors not cleared by the Patrol Division and all felonies. The division is responsible for a number of specialized units. Many are described below.
Crime Analysis Unit
Our crime analyst works alongside officers, detectives and the Douglas County Impact Team to analyze data from records and calls for service. The data is analyzed daily to define trends and patterns. The analyst creates spatial and temporal analytics (time and location), trend reports, deployments, forecasts, predictions, and more. The analyst coordinates our agency's crime data not only with Douglas County agencies but throughout the Denver Metro area and Front Range. These products are generated for our officers' and detectives' use to help solve and prevent crimes.

Impact Unit
Castle Rock Police Department participates in this multi-jurisdictional team, which consists of detectives from Castle Rock, Lone Tree and Parker police departments as well as the Douglas County Sheriff's office. The unit focuses on criminal offenses, behaviors and street level narcotic trafficking based on repeated patterns and methods. The Investigations Division reassigned one detective to this team.
Property and Evidence Unit
Following Department guidelines, our property and evidence technician works alongside a detective and volunteer staff to log, store, secure and release all evidence and other property received.

The technician also assists in officer training regarding proper collection and the packaging of evidence. During major crime scenes, the technician assists in transporting and logging the numerous pieces of evidence.

Victims Assistance Unit


The Victim Assistance (VA) Unit works alongside crime victims with fairness, dignity and respect during a traumatic time or having experienced tragic events. The unit ascertains that the rights of all victims have been afforded to them through the Colorado Constitution Victims’ Rights Act, C.R.S. 24-4.1-302. Our job is to provide victims and witnesses of criminal offenses with the support and aid necessary to mentally and physically adjust to their victimization.  Other duties include providing referral information and making outreach contact. Victim advocates are the liaison between the criminal justice system and the victim. All of the services are developed to competently serve victims of all cultures and ethnic backgrounds. 

The Victims Assistance Unit currently consists of a victim assistance coordinator and a victim advocate. The unit has 10 additional victim assistance volunteers from within our community. More information on volunteering opportunities within this Unit may be found here.
