Latent Print Processing Guide

Latent prints are chance or accidental impressions left by friction-ridge skin on a surface, regardless of whether they are visible or invisible at the time of deposition. Recognition of evidence that may contain fingerprints and the processes that can develop these latent prints is crucial in preventing valuable evidence from being left undetected. Latent Print Processing Guide goes beyond the basic police training, covering latent prints in detail and providing first responders with adequate training and guidelines. To process latent prints, examiners use various techniques including electronic, chemical, cyanoacrylate, and physical methods. Latent Print Processing Guide offers a broad understanding of latent print detection, development, and recovery, including insights on stateof-the-art technologies. Includes history of latent print identification and some of the pioneers and their contributions. Defines the differences between chemical and physical processes and explains process sequence protocols and recovery methods for different types of evidence. Chapters include: process selection, application and recovery, special considerations for specific materials, protocol sequence and process formulas, including required materials, application method, expected results, safety measures, and references. The text is written so that non-crime scene or non-crime laboratory personnel can also gain valuable information from it.
