The Latent Print Unit examines evidence items for the presence of latent prints. Evidence items can be visually, chemically and physically processed. When latent prints of value are found, they are preserved. An analysis, comparison, evaluation and verification of an unknown and known print impressions is conducted determine the source of the latent print. When no identifications are effected or no subjects for comparison are provided, latent prints can be searched in the Automated Fingerprint Identification System (AFIS). AFIS is a computer-based system which houses and retrieves prints. Latent Print Examiners in this unit also maintain case notes and generate lab reports regarding results of examinations, provide crime scene response and training in latent print matters, and courtroom testimony.
