The Latent Print and Impression Evidence section of the DCI Crime Laboratory examines submitted evidence for the presence of fingerprints, footwear/tires, and Automated Fingerprint Identification System (AFIS) entry. The techniques used in the development of latent prints range from traditional fingerprint powdering techniques and superglue fuming, to advanced techniques such as fluorescent dye stains and alternate light sources.

Latent print examiners attempt to identify latent prints from crime scenes to individuals. If they are not identified or there is no known suspect for the crime, then the identifiable latent prints are entered into AFIS, a state-wide database of finger and palm prints, and/or the FBI’s Next Generation Identification (NGI), a nation-wide database of finger and palm prints.
Footwear and Tire Track examinations (Impression Evidence) are also conducted at the laboratory, and are similar to Latent Print examinations, except the evidence are shoes and tires.
