Instructor: Sharon Plotkin, EDD, CCSI
Course length: 40 hours

Modern Fingerprint Development and Documentation course is a comprehensive workshop that includes a historical perspective regarding latent fingerprints, physical and chemical processing of latent fingerprint evidence as well as latent print photography. The course will provide lectures, power points, hand out materials and many hands-on practicums to ensure all objectives are met.
 
Objectives:
            - Introduction to the anatomy and physiology of latent prints and latent print residue
            - Major case prints and exemplars
            - Personal protective equipment (PPE)
            - Alternate light source
            - Latent print processing: Porous and Non-Porous surfaces
            - Latent print processing: challenging surfaces
                        - human skin, wet surfaces, tape adhesive, fabrics, wood, greasy surfaces
            - Enhancement and detection of fingerprints in blood
            - Fingerprint evidence photography including alternate light source photography
 
At the conclusion of this Modern Fingerprint Development & Documentation course, the student should understand the physiological components of latent print residue, importance and collection of major case prints and identify the most effective latent print processing technique(s) with a consideration of surface and environmental considerations.

The student will learn how to preserve the latent print evidence using alternate light sources and utilizing advanced photography techniques.
