Course length: 24 hours

Not all fingerprints can be seen with the human eye. Experienced crime scene and law enforcement personnel understand this. To overcome this challenge chemicals, dye stains and alternate light sources are utilized in successfully locating, documenting and collecting this important evidence to assist lab personnel in analyzing and identification.

The purpose of this 24-hour Advanced Fluorescent Fingerprint Processing & Photography workshop is to introduce to crime scene and law enforcement personnel how to utilize alternate lights sources, chemicals and dye stains in detecting and enhancing evidence effectively so that the fingerprint lifts can be analyzed and evaluated.  Photographing these developed latent fingerprints is also important and will be addressed in this workshop.

Course Objectives:

The objective of this Advanced Fluorescent Fingerpront Processing & Photography course is to introduce attendees how to use chemicals and dye stains on challenging surfaces utilizing the most effective techniques, then to photograph these developed latent fingerprints with an alternate light source. Several fingerprinting techniques will be discussed, examined and utilized. Attendees will utilize chemicals such as Basic Yellow, Ardrox, Cyanoacrylate, MBD, Ninhydrin, DFO, Indanedione, Iodine, RAM and fluorescent powders in locating fingerprint evidence. Chain of custody, such as property receipts, packaging of fingerprint evidence will also be introduced.
