The Forensic Latent Print Identification Unit examines and compares unknown to known dermal friction ridge detail. Processing techniques includes physical, chemical, and fluorescent development of latent print evidence. For unidentified suspect investigations, the Automated Fingerprint Identification System (AFIS) database entry/inquiry is employed. When a case is submitted without a suspect, the unknown fingerprints are entered into the system. Potential candidates are generated by the system but the comparison and identification must be made by a forensic scientist. The unit also conducts examinations of footwear impressions and tire impressions.
