Criminalistics Section

Members of the Criminalistics Section recognize, document, analyze, interpret, and testify to the significance of physical and biological evidence submitted to the Crime Laboratory. They perform presumptive and confirmatory tests for the presence of blood, semen, saliva, urine, and feces. They also do initial classification of trace evidence such as hairs and fibers, and perform chemical testing for gunshot residues and distance determination. Criminalists recognize items and stains that may need further individualization by other units within the laboratory such as the Trace Analysis Unit, Arson and Explosives, and DNA Units.
