Fingerprints: Forensic Science-CERTIFICATION (ACCREDITED)

Learn to classify fingerprint patterns into arches, loops, and composites, using deltas and cores to distinguish plain, tented, radial loops, central pocket loops, and accidental patterns.

Learn why fingerprints are recorded for bureau records, suspect identification, and crime-scene comparisons. Follow the recording procedure with a slab, ink, roller, and forms, ensuring clean fingers and even ink.

Explore the three main classes of fingerprints—visible, plastic, and latent—and how investigators photograph, develop, and reveal latent prints using physical and chemical methods such as dusting, iodine fuming, and ninhydrin.

Explore physical methods for latent print development, including powder formulations, border choices, fluorescent and iodine techniques, and lifting or imaging on various surfaces.

Examine chemical methods for latent print development, including silver nitrate and silver chlorate with light exposure, and the ninhydrin process yielding purple prints from amino acids after Iogen filming method.

Explore other methods of fingerprint development, including laser-based development, latent fingerprint luminescence tests, inherent luminescence, gamma-induced luminescence, and electromyography for deceased skin.

Explore the Henry system of fingerprint classification, including primary, secondary, and final classifications, and how numerical and non-numerical patterns across all ten fingers determine the classification.

Identify fingerprints by comparing general patterns and minutiae, including up to 150 characteristics, ensuring same pattern, direction, and positions, and matching counts to confirm latent and known prints.

Palm prints serve as forensic evidence and help establish identity; record impressions like fingerprints, using ink rolled onto slips to identify palm areas with proximal and distal ends.
