About the Section

The Latent Print section locates, processes, preserves, examines, and compares friction ridge impressions.

Latent prints are impressions produced by the friction ridge skin on the fingers, palms, and soles of the feet. The uniqueness, persistence, and arrangement of those ridges allow the section to determine whether two friction ridge impressions originated from the same source.

A latent fingerprint developed on an item of evidence.

Services

Criminalists in the Latent Print section examine submitted evidence for the presence of friction ridge skin impressions. They develop, preserve, and collect these impressions. After discovery of unknown impression evidence, they compare the unknown prints against submitted known prints.

Upon completing the comparison, the examiner renders a scientific conclusion and writes a report of the results of the examination. Criminalists can be called upon to testify in courts of law as to the results of their examination.

Techniques and Equipment

Fingerprints are placed into a computerized database called the Automated Fingerprint Identification System, known as AFIS. AFIS allows a fingerprint to be entered and searched by points of identification within the finger, so that a print left at a crime scene can be searched and identified before or during examination by a criminalist.

A variety of techniques are used in the detection and development of latent prints, including chemicals, powders, alternate light sources, and other physical means.
