The Colorado Human Remains Extraction and Recovery Team (COHEART) was developed in accordance with a grant funded by the Urban Area Security Initiative (UASI) under the Department of Homeland Security. COHEART encompasses the North Central Region (NCR), UASI, and all jurisdictions within the nine county NCR all hazards regions. The Denver Office of the Medical Examiner and NCR instituted this unique program to establish a volunteer force to assist in the medicolegal investigation of human remains in the event of a mass casualty event. A mass casualty is a situation in which the resources needed for the recovery and examination of human remains are above the capacity of local agencies. Traditionally law enforcement, EMS, and fire departments provide assistance in these situations whilst performing their own duties. COHEART utilizes trained citizen volunteers to aid local agencies during a mass casualty event. Currently the team is comprised of approximately 200 members of all different experience levels and areas of specialties.
