Special Investigations - Evidence Response Team

The Evidence Response Team was formed in August of 1999. This team responds to assist in all cases consisting of suspicious death, homicide, suicide and other critical incidents.

If you have information pertaining to a crime, please contact the Criminal Investigations Division at (423) 209-8940 during regular business hours, or call Hamilton County Sheriff’s Office dispatch at (423) 622-0022.

Goals and Objectives

  • To process crime scenes in a professional manner providing a foundation for the successful prosecution of offenders and exclusion of the innocent.
  • To establish and apply general guidelines for the processing of crime scenes.
  • To provide a team approach for major incidents, freeing up case agents to follow up on information during the first twenty-four hours of a critical incident.

The first step taken by the Criminal Investigation Division was to equip an evidence response vehicle with basic equipment and packaging items necessary for the processing of scenes. With the assistance of HCSO Motorpool, the unit converted an old county ambulance into a crime scene van. Since inception, equipment has been added including digital cameras, a forensic light kit, trace hair and fiber recovery kit, tools necessary for the recovery of evidence as well as existing latent and casting equipment. The division also utilizes a Cyanoacrylate chamber to assist in developing fingerprints.

Since the inception of the Crime Scene Unit, the department has 4 investigators that have graduated from The National Forensic Academy (NFA), which an intensive 10-week training program, funded by the Bureau of Justice Assistance, designed to meet the needs of law enforcement agencies in evidence identification, collection, and preservation. The NFA is offered in-residence, utilizing curriculum developed by leading forensic practitioners from across the United States. Participants are challenged in the various disciplines through classroom instruction, lab activities, and field practicums in the specialized courses. Academy participants completed written and in-class competency exams to demonstrate mastery of the subject areas. The Academy prepares the crime scene investigator to recognize key elements and to improve the process of evidence recovery and submission.
