Summary : 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.

Summary : 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.

Summary : Latent fingerprints are made visible from the surface of objects using a variety of methods including physical and chemical processing, adapted illumination sources, and photographs. Unfortunately, the prints collected directly from a crime scene or from physical evidence may be incomplete or damaged, to the point of being considered unsuitable to send directly to latent fingerprint examiners for identification or to Automated Fingerprint Identification System (AFIS) for recognition. As a result, most latent fingerprint images must be preprocessed to enhance fingerprint information, at the same time suppressing interference arising from noise and otherwise unwanted image features. This preprocessing phase occurs after the latent print is collected from the crime scene and digitalized by a scanner or camera, and before the image analysis and process phase such as minutiae markup or latent print identification. The preprocessing results can be extraordinary, transforming raw images with little or no value into ones suitable for evidentiary analysis. Despite the importance of this step, there exist few databases designed especially for the scientific study of latent fingerprint image preprocessing, and even fewer standards to guide this workflow. To address this research gap, we conducted a study in which a group of trained Latent Print Examiners provided Extended Feature Set (EFS) markups of a series of latent images. This report provides a brief introduction into fingerprint preprocessing, discussion regarding the experimental design, structure, and contents of the latent fingerprint image database, and details of proposed preprocessing efficacy metrics. Additionally, we present preliminary analysis of these metrics when applied to images in our database. Previously Guan et al. [6] presented the performance metrics and analysis of the metrics as applied to a union minutiae set. In this report, we comprehensively document the contents of the records database including the latent images, the EFS markup files, metadata, markup logs, and region of interest masks. Additionally, we present the results of the performance metrics as applied to the intersection minutiae set of EFS markup data.

Summary : This specially developed workbook can be used in conjunction with the Complete Crime Scene Investigation Handbook (ISBN: 978-1-4987-0144-0) in group training environments, or for individuals looking for independent, step-by-step self-study guide. It presents an abridged version of the Handbook, supplying both students and professionals with the most critical points and extensive hands-on exercises for skill enhancement. Filled with more than 350 full-color images, the Complete Crime Scene Investigation Workbook walks readers through self-tests and exercises they can perform to practice and improve their documentation, collection, and processing techniques. Most experienced crime scene investigators will tell you that it is virtually impossible to be an expert in every aspect of crime scene investigations. If you begin to "specialize" too soon, you risk not becoming a well-rounded crime scene investigator. Establishing a complete foundation to the topic, the exercises in this workbook reinforce the concepts presented in the Handbook with a practical, real-world application. As a crime scene investigator, reports need to be more descriptive than they are at the patrol officer level. This workbook provides a range of scenarios around which to coordinate multiple exercises and lab examples, and space is provided to write descriptions of observations. The book also supplies step-by-step, fully illustrative photographs of crime scene procedures, protocols, and evidence collection and testing techniques. This lab exercise workbook is ideal for use in conjunction with the Handbook, both in group training settings, as well as a stand-alone workbook for individuals looking for hands-on self-study. It is a must-have resource for crime scene technicians, investigators, and professionals who want a complete manual of crime scene collection and processing techniques.

Summary : 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.

Summary : Evidence Found: An Approach to Crime Scene Investigation is not another analysis of forensic errors using an "After the Fact" or "Lessons Learned" approach but a "Before the Fact" guide that examines the thought processes that can lead to those mistakes. Plus a few extras tips and tricks from the author’s experience of over 25 years. Many high-profile crime scene investigations (and routine ones, for that matter) have suffered errors that have had negative impact on the investigation result and in the courtroom. Typically, we examine what happened and develop a useful list of what to do and what not to do, fixing the symptoms but potentially leaving ourselves open to the same error type on the next scene. The reason? Many crime scene mistakes are the result of systemic issues that are repeated due to a failure to include an evaluation of the decision-making process, including our own foundations of knowledge. Through case study and logical argument, this book attempts to provide a framework to recognize, evaluate, and alter negative decision-making patterns, including evaluating our own experience, before they negatively impact an investigation or the overall operation of a forensic unit. Enhances the base concepts of evidence search and sequential processing for error avoidance Examines the systemic areas/practices of a crime scene investigation where errors can occur Includes a Evidence Matrix - a crime scene evaluation tool that aids in sequential processing decisions Contains tips on overcoming common crime scene issues, inlcuding night time searches Provides courtroom Testimony - communicating comparison findings to a jury

Summary : 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.
