DOWNLOAD EBOOK →Crime scene investigation involves the use and integration of scientific methods, physical evidence, and deductive reasoning in order to determine and establish the series of events surrounding a crime. The quality of the immediate crime scene response and the manner in which the crime scene is examined are critical to the success of the investigation. Evidence that is missed or corrupted by incomplete or improper handling can have a devastating effect on a case and keep justice from being served. The Practice of Crime Scene Investigation covers numerous aspects of crime scene investigation, including the latest in education and training, quality systems accreditation, quality assurance, and the application of specialist scientific disciplines to crime. The book discusses a range of basic and advanced techniques such as fingerprinting, dealing with trauma victims, photofit technology, the role of the pathologist and ballistic expert, and signal processing. It also reviews specialist crime scene examinations including clandestine laboratories, drug operations, arson, and explosives.

DOWNLOAD EBOOK →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.

DOWNLOAD EBOOK →Since its publication, the first edition of Fingerprints and Other Ridge Skin Impressions has become a classic in the field. This second edition is completely updated, focusing on the latest technology and techniques—including current detection procedures, applicable processing and analysis methods—all while incorporating the expansive growth of literature on the topic since the publication of the original edition. Forensic science has been challenged in recent years as a result of errors, courts and other scientists contesting verdicts, and changes of a fundamental nature related to previous claims of infallibility and absolute individualization. As such, these factors represent a fundamental change in the way training, identifying, and reporting should be conducted. This book addresses these questions with a clear viewpoint as to where the profession—and ridge skin identification in particular—must go and what efforts and research will help develop the field over the next several years. The second edition introduces several new topics, including Discussion of ACE-V and research results from ACE-V studies Computerized marking systems to help examiners produce reports New probabilistic models and decision theories about ridge skin evidence interpretation, introducing Bayesnet tools Fundamental understanding of ridge mark detection techniques, with the introduction of new aspects such as nanotechnology, immunology and hyperspectral imaging Overview of reagent preparation and application Chapters cover all aspects of the subject, including the formation of friction ridges on the skin, the deposition of latent marks, ridge skin mark identification, the detection and enhancement of such marks, as well the recording of fingerprint evidence. The book serves as an essential reference for practitioners working in the field of fingermark detection and identification, as well as legal and police professionals and anyone studying forensic science with a view to understanding current thoughts and challenges in dactyloscopy.

DOWNLOAD EBOOK →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.

DOWNLOAD EBOOK →THE FORENSIC ANALYSIS, COMPARISON AND EVALUATION OF FRICTION RIDGE SKIN IMPRESSIONS An accessible, highly practical introduction to the ACE framework fingerprint examiners use to analyse, compare and evaluate friction ridge skin impressions. When friction ridge skin (the skin on the undersides of the hands and feet) contacts a surface an impression of it may be left behind. Impressions that are left inadvertently, for example at a scene where a crime is alleged to have been committed are known as ‘marks’. Impressions taken intentionally from a person, for example as a result of their arrest are known as ‘prints’. The Forensic Analysis, Comparison and Evaluation of Friction Ridge Skin Impressions offers step-by-step instruction to examiners tasked with identifying people by the marks they leave behind. Assuming no previous knowledge of the subject, this easy-to-use guide breaks down the ACE (Analysis, Comparison and Evaluation) framework into 10 key questions that provide clear guidance on: establishing the most evidentially valuable mark; the type of details the mark may reveal; the effects of distortion; how to determine which area of skin is most likely to have made the mark, and more. Author Dan Perkins draws upon his years of experience to equip fingerprint examiners with the key skills needed to carry out the appropriate analysis, comparison and evaluation of friction ridge skin impressions. Presents a stepwise approach designed for both novice and more experienced fingerprint examiners Discusses all aspects of ACE, including the formation of fingerprints, documentation, suitability, and orientation Contains references to relevant research, real-world case studies, and hundreds of impressions the reader can analyse and compare Includes five detailed appendices covering fabrication, transplantation and forgery, verification, bias, activity level propositions, and errors The Forensic Analysis, Comparison and Evaluation of Friction Ridge Skin Impressions is an indispensable ACE ‘checklist’ for trainees in the field of fingerprint comparison and identification, qualified fingerprint examiners and forensic science students.
