Through the comparison process, an examiner is able to determine whether a particular latent print is identified to a subject in question.
The Latent Print Unit conducts scientific examinations in the area of friction ridge analysis, including the comparison of latent fingerprints, palm prints and footprints recovered from crimes scenes to known subject’s standards. Through the comparison process, an examiner is able to determine whether a particular latent print is identified to a subject in question.
As part of the scientific process, all identifications are examined by a second latent print examiner to verify the original identification. Unidentified latent prints, may be entered and searched in the Automated Fingerprint Identification System (AFIS). This computer system contains a database of known individuals and is used to retrieve a candidate list. Each candidate on this list is ultimately compared by a latent print examiner to determine if there is an identification. Latent prints that have been searched in AFIS and not identified remain in the unsolved latent file (ULF) and are searched daily as new individuals are added to the database. The system also assists the examiner in locating and retrieving records of known standards. Latent Print Examiners are responsible for reporting their findings and providing expert witness testimony relating to these examinations.
