    A specialized group of deputies investigates felony crimes committed in unincorporated Jefferson County and files cases with the district attorney's office.

    Crimes Against Persons Unit

    The persons unit investigates homicide, sexual assault (adult victim), kidnapping, domestic violence, serious assault cases, robberies, missing persons and unattended deaths. This team has investigators who specialize in cold case homicides.

    Crimes Against Property Unit

    This team is assigned to investigate felony property crimes, including burglary, theft, motor vehicle theft, criminal mischief, trespass and other crimes. Investigators have found that many of the property-related crimes that occur in this county are crimes of opportunity. Suspects tend to take the path of least resistance by looking for open or unlocked doors. For crime-prevention tips, visit our Crime Prevention page.

    Crimes Against Children Unit

    This unit is responsible for investigating all felony crimes committed against and by juveniles. Additionally, investigators are responsible for tracking juvenile offenders, runaways and the registered sexual offenders living in unincorporated Jefferson County.

    Special Investigations Unit

    The special investigations unit investigates the following crimes: domestic and international terrorism; liquor violations; vice; complex crimes; identity theft; fraud; forgery; computer forensics; and gang activity. Investigators work closely with investigators from the United States Postal Service on cases involving stolen mail. The special investigations unit also conducts concealed weapon permit and federal firearms license background checks and investigates permit violations.

    West Metro Drug Task Force

    The Jefferson County Sheriff's Office is one of five local law enforcement agencies contributing personnel and manpower to the West Metro Drug Task Force. View exit disclaimer policy page for links to third-party websites. The group was formed in 1992 as an intergovernmental team to investigate and prosecute individuals and groups involved in illegal-drugs trafficking and associated criminal enterprises. The task force was designed to reduce the amount of illegal drugs available in the community by sanctioning those who provide the drugs.

    Jefferson County Regional Crime Laboratory

    The Jefferson County Regional Crime Laboratory is responsible for crime scene response and processing, polygraph tests, forensic photography, latent print comparison, questioned documents, controlled-substance analysis and clandestine drug laboratory analysis. The laboratory also provides training to the Jefferson County Sheriff's Office deputy and citizens' academies and the crime scene technician program.

    Evidence Vault

    The Jefferson County Sheriff's Office evidence vault contains physical evidence relating to criminal cases in unincorporated Jefferson County. Evidence vault custodians ensure the integrity of all stored evidence and property, and they produce these items quickly and accurately for legal proceedings.

    The vault processes and stores more than 13,000 items each year. Items are periodically purged on a case-by-case basis (following adjudication), based on instructions from deputies and investigators involved. Property is returned to owners, destroyed, converted to county property or auctioned.

    Victim Services

    Four full-time and nearly 30 volunteer victim advocates respond to the needs of crime and crisis victims by providing crisis intervention, support, referrals and help with the criminal justice process. Advocates work with victims on-scene or immediately following a traumatic event, and they may refer victims to mental health professionals for long-term care or community assistance programs. Work done by the victim services unit is based on the Colorado Victim's Bill of Rights. Victim Services also administers the "Deputy Hugs" adopt-a-bear program. See more information on victim services and victims' rights on our victim services page.
