Book Description
This revised and expanded edition of Dr. Menzel's 1980 book is lcome book for latent print examiners, forensic scientists, and scientists interested in the fascinating field of latent print visualization. It updates his previous book by including new and advanced optical imaging techniques that have emerged in the last 20 years. These include CCD cameras, near-infrared imagers, ultraviolet imagers, and acousto-optical tunable filters. It also treats new developments in latent print visualization that have occurred during this time such as the use of DFO, ninhydrin analogues, rare-earth chelates, 1,2-indanediones, multi-metal deposition method, and DMAC. Each chapter is well referenced.

Book Description
Fingerprint development techniques that use blue-green laser light suffer from high background fluorescence on substrates such as cardboard, wood, leather, and some metals and plastics. These substrates tend to exhibit little or no fluorescence under ultraviolet light, prompting us to search for procedures that yield visible fluorescence under this illumination. Specifically, chemical development with dansyl chloride and vapor staining with 9-methylanthracene were found to be useful when dealing with these substrates. Fluorescence excitation was possible either with an ultraviolet lamp or an argon-ion laser operating in the ultraviolet. Coumarin 535 vapor staining following 9-methylanthracene staining was also found effective.

Book Description
Laser detection of fingerprints, as described in an earlier paper [1], entails exposure of crime scene exhibits to laser light and photography (or direct viewing) of any fingerprints thereby induced. The Ontario Provincial Police Force has initiated laser examination of exhibits for fingerprints to evaluate the effectiveness of this technique and to obtain additional data that might further exploit the luminescence of fingerprints on materials under examination. Glass, metal, wood, cloth, stone, and plastic exhibits were examined for fingerprints under laser light. Many of these surfaces yielded localized luminescence that may or may not have been the result of fingerprint deposit.

Book Description
First published in 1996, this work covers all the major sectors of policing in the United States. Political events such as the terrorist attacks of September 11, 2001, have created new policing needs while affecting public opinion about law enforcement. This third edition of the "Encyclopedia" examines the theoretical and practical aspects of law enforcement, discussing past and present practices.

Book Description
In 1976 a method for the detection of latent fingerprints by their inherent luminescence using continuous-wave (CW) argon-ion laser excitation [1] was discovered at Xerox Research Centre of Canada, where the first detection by this method of an identified print from an actual criminal exhibit (a fingerprint on the sticky side of a piece of black electrical tape) was also achieved. Basically, the laser procedure involves illumination of the exhibit under scrutiny with the blue-green light from the argon-ion laser and photography of the resulting yellow-green fingerprint luminescence. The viewing and photography are carried out in a darkened room. A filter is used to block the laser light scattered from the exhibit to prevent eye damage and film exposure by the laser light. Spectroscopic and chromatographic features of fingerprint material indicate that riboflavin is one of several inherent luminescers in fingerprint residue and our findings suggest potential for fingerprint age determination [2].
