Digital Forensic Art Techniques: A Professional's Guide to Corel PainterTM illustrates hands-on techniques to digitally create forensic art for police and investigative purposes. Coverage focuses specifically on how to utilize the software to create realistic human likenesses, including composites of suspects and drawings of persons in unidentified remains cases. Drawing digitally is like using any tool in art: a pencil, a charcoal stick, a conte' crayon. A stylus is just another tool to master. Digital work is easier for artists to send to the case detective, and the work always reproduces exactly as it was completed. Another benefit to working digitally is that one can use video conferencing with a witness online to provide services remotely world-wide. This enables police departments who have never had access to a forensic artist to have a sketch done within hours of the crime. Chapters address the more basic functions to serve as a primer for those transitioning to working digitally. There is also instruction on light and shadow, and bones and muscles of the skull. All of the discussion is intended to make the reader see things as an artist to improve drawing skills and overall digital techniques. In short, Digital Forensic Art Techniques is a practical, easy-to-follow manual for working forensic artists that will give readers a solid base from which to start. It serves as an essential resource to greater skill and comfort with the hardware and software, thus furthering current best practices and technological advances in the field.

A thumb print left at the scene of a grisly murder. Fingerprints taken from a getaway car used in a bank robbery. A palm print recovered from the shattered glass door of a burglarized home. Indeed, where crimes are committed, careless perpetrators will invariably leave behind the critical pieces of evidence-most likely in the form of fingerprints-needed to catch and convict them. But the science of fingerprint identification isn't always as cut and dry as detective novels and movies make it out to be.
Quantitative-Qualitative Friction Ridge Analysis, a new book in the ongoing Practical Aspects of Criminal and Forensic Investigations series, examines the latest methods and techniques in the science of friction ridge identification, or ridgeology.

Despite the increasing use of DNA evidence and other sophisticated forensic techniques in crime solving, fingerprints still serve as an indispensable tool of modern-day criminal investigation. This fascinating book, originally published in 1892, represents the first thorough investigation of this anatomical peculiarity and its application in establishing individual identity for use in law enforcement. Sir Francis Galton, a cousin of Charles Darwin and a member of the Royal Geographical Society, had already made a reputation for himself as an explorer of Africa and the founder of the new field of eugenics when he turned his attention to the subject of fingerprints. Through extensive research at his "anthropometric laboratory," Galton laid out an elementary system of classifying fingerprints based on observed patterns of arches, loops, and whorls. Using meticulous drawings as well as photographs of ink prints, he showed that "the numerous bifurcations, origins, islands, and enclosures in the ridges that compose the pattern, are proved to be almost beyond change." Thus, he established a sure method of individual identification. Galton's system was later modified by Sir Edward R. Henry, who became chief of police in London. In 1901, Scotland Yard officially adopted the Galton-Henry system of fingerprinting. Today, it is the most widely used system of fingerprint classification in the world. This classic work will make a welcome addition to the libraries of historians, criminologists, and fans of true crime and forensic science.

This book exposes the dangerously imperfect forensic evidence that we rely on for criminal convictions. "That's not my fingerprint, your honor," said the defendant, after FBI experts reported a "100-percent identification." The FBI was wrong. It is shocking how often they are. Autopsy of a Crime Lab is the first book to catalog the sources of error and the faulty science behind a range of well-known forensic evidence, from fingerprints and firearms to forensic algorithms. In this devastating forensic takedown, noted legal expert Brandon L. Garrett poses the questions that should be asked in courtrooms every day: Where are the studies that validate the basic premises of widely accepted techniques such as fingerprinting? How can experts testify with 100-percent certainty about a fingerprint, when there is no such thing as a 100 percent match? Where is the quality control at the crime scenes and in the laboratories? Should we so readily adopt powerful new technologies like facial recognition software and rapid DNA machines? And why have judges been so reluctant to consider the weaknesses of so many long-accepted methods? Taking us into the lives of the wrongfully convicted or nearly convicted, into crime labs rocked by scandal, and onto the front lines of promising reform efforts driven by professionals and researchers alike, Autopsy of a Crime Lab illustrates the persistence and perniciousness of shaky science and its well-meaning practitioners.
