As forensic technology becomes more sophisticated, courts are demanding more scientific content and juries are expecting meticulous confirmation of facts alleged. Greater attention is now paid to increasingly finer details and improved methods of describing every form of evidence. Applying physics, chemistry, and engineering to the process of analysis and interpretation, Mechanics of Impression Evidence reflects the shift to these heightened standards and offers a starting point for significant change in the way that impression evidence is considered, utilized, and presented. Concepts discussed in this groundbreaking text include: The three-dimensional nature of the human fingerprint and a shift toward a more holistic image of the surface of friction skin Dimensional stability and striation mark issues, which can change the way footwear outsoles are evaluated and compared The research and development of electrostatic scans that could possibly save lives and locate or describe evidence as never before The growing availability of new measurement techniques that can improve evidence testimony The use of personal experimentation to support conclusions or confirm that which is otherwise considered fact Making use of logic and science to question our approach to impression evidence, this volume begins with simple ideas and basic notions and uses these building blocks to suggest and consider potentially controversial changes in the way evidence is located, interpreted, compared, and presented.

The utilization of footwear impression evidence continues to evolve with new materials, equipment and techniques, providing an increased ability to detect, record, enhance, and examine this form of evidence. Recently developed technology now allows investigators to more efficiently or, in some cases, instantly link multiple crime scenes where impressions have been produced by the same perpetrator. Forensic Footwear Evidence covers a wide range of relevant topics, including historical references, general information about the formation and investigative use of footwear impressions, and the best practices and considerations that apply to the recovery, enhancement, and examination of this evidence. Drawing on the author’s 44 years of acquired knowledge and experience, it is the most comprehensive and authoritative text published to date on this topic. Highlighted topics covered within the book include Three chapters covering footwear manufacturing Shoe grading, sizing, and the forensic application of sizing information Examination and reporting procedures Casting impressions in snow Barefoot evidence Topics of interest for both prosecution and defense attorneys The book includes more than 300 color photographs and illustrations throughout, as well as case examples that apply theoretical concepts to the real world. A single, complete reference on the subject, Forensic Footwear Evidence presents a wide range wealth of information that will serve as an invaluable reference to novice and experienced examiners, crime scene technicians, investigators, and prosecution and defense counselors alike.

The digital revolution over the past several decades has advanced every facet of evidence detection, photography, optimization, and interpretation. Forensic scientists and practitioners have benefited tremendously from the move from film to digital. With proper procedures in place, digital images and casework capabilities have increased tremendously in both complexity and range due to a vast array of tools to enhance evidence and photography. Forensic Digital Image Processing: Optimization of Impression Evidence provides the forensic investigator with the tools and understanding to extract, optimize, and interpret the maximum evidence possible from crime scenes to increase identifications. The book begins by examining the emergence of forensic digital image processing, and the gradual improvement and acceptance of the science over the past four decades. Coverage includes looking at the issues of image integrity and authentication including forensic image optimization and the manipulation of images.? Chapters explore techniques exploiting color theory, modes, and channels to optimize signal-to-noise ratio in images. One of the greatest assets of digital image technology is the ability to combine multiple images of the same subject to create a final, blended image: one that displays the desired evidence and is especially useful for fingerprint or footwear impression. Later chapters demonstrate image subtraction, focus stacking, and high dynamic range, utilizing images in optimum focus and with substrate interference diminished or removed entirely. The authors look at fast Fourier transform as an optimal tool for noise removal, addressing basic theory and diagnosis of the noise signatures. The book discusses the history of digital imaging techniques and their treatment within the court system. Forensic Digital Image Processing: Optimization of Impression Evidence serves as an invaluable resource and tool for practicing professionals–as well as those new to the field—to look at best practices, the latest technology, and advances in utilizing the increasing array of tools of the trade.

Police success in linking vehicles to the scene of a crime through the impressions and tracks those vehicles leave behind has long served as a successful and reliable forensic tool. The collection and forensic evaluation of that evidence, however, requires specialized knowledge, training, and expertise. Drawing from the author’s 34 years of experience, first as an FBI examiner and currently as a private consultant in the area of tire evidence, Tire and Tire Track Evidence: Recovery and Forensic Examination is the most comprehensive and up-to-date volume available on the subject. Covering all aspects of the field, the book begins with general information on the modern pneumatic tire and basic terminology. For both the crime scene technician and the forensic examiner, the author addresses information on both how to recover tire track evidence and how to photograph and cast the individual tread detail from those impressions. The book explains and illustrates the necessary information on obtaining known exemplars; tire manufacturing, and retreading tires. It explains important aspects of tires including their tread design and dimension, noise treatment, general wear and individual acquired characteristics. The author instructs on applying that knowledge while conducting a structured examination procedure, resulting in the final evaluation of evidence and report writing as well as the presentation of tire evidence in court. He provides information on databases and resources along with case examples, including the Oklahoma City bombing. Informative and useful, this book gives crime scene technicians and forensic examiners the tools to accurately and reliably collect, recover, and examine tire evidence.
