Book Description
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.

Book Description
The idea of The Fingerprint Sourcebook originated during a meeting in April 2002. Individuals representing the fingerprint, academic, and scientific communities met in Chicago, Illinois, for a day and a half to discuss the state of fingerprint identification with a view toward the challenges raised by Daubert issues. The meeting was a joint project between the International Association for Identification (IAI) and West Virginia University (WVU). One recommendation that came out of that meeting was a suggestion to create a sourcebook for friction ridge examiners, that is, a single source of researched information regarding the subject. This sourcebook would provide educational, training, and research information for the international scientific community.

Book Description
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.

Book Description
Fingerprints: Analysis and Understanding the Science, Second Edition is a thorough update of Mark Hawthorne’s classic written by two professionals with combined experience not only in crime scene investigations but also as court-recognized experts in latent print examination. Designed as a concise text to cover the fundamental techniques and principles of obtaining and analyzing latent fingerprint evidence, the book is laid out and written in an easy to understand format for those front-line professionals collecting and analyzing fingerprint evidence. Over time, the degree of sophistication and education on fingerprints and friction ridge analysis has increased. Ultimately, through scientific study by pioneers in the field, the composition of friction skin soon became evident: that it could be used as a unique identifier of individuals. Now, fingerprints and footprints as unique identifiers—and their use in criminal cases—have become commonplace and an essential component of criminal investigation with most cases involving some component of fingerprint evidence. Divided into two parts, the book begins with the basics of analysis, providing a brief history, systematic methods of identification, fingerprint pattern types and their associated terminologies and current classifications. The second part of the book discusses the identification and presentation of evidence in the courtroom, demonstrating both the traditional, manual method of lifting prints and the newer techniques for automated and live scans. Coverage provides instruction on searching and developing latent prints, storage, and comparison of prints. New to this edition are updated techniques on collecting and preserving fingerprint evidence—including packaging and maintaining chain of custody. More detailed documentation processes, and additional chemical and lifting techniques, are described including use of light sources, latent backing cards and lifting material, casting material, ten print cards, and the enhancement of prints in blood. A discussion of laboratory equipment and comparison tools, the addition of photography techniques, and recent courtroom challenges to fingerprint evidence is also presented. Fingerprints, Second Edition will provide a hands-on, fresh look at the most commonly utilized evidence found at crime scenes: fingerprints. The book will provide law enforcement, crime scene personnel and students just such an opportunity to easily understand and grasp the concepts, and relevant issues, associated with friction skin and fingerprint evidence.

Book Description
Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.
