A Practical Guide To The Forensic Examination Of Hair

A Practical Guide to the Forensic Examination of Hair: From Crime Scene to Court presents current best practices and methodologies for forensic microscopists and trace evidence analysts, in addition to lawyers and judges, to detail the utilisation of hair evidence in court cases. The 30-year evolution and development of forensic DNA analysis has placed very heavy focus on its value in identifying the source of biological materials in other evidence. In addition to some recent controversies over the reliability of hair evidence and analysis, the question arises: what to do with hairs and hair evidence presented in court cases? The reality is that this is a fairly common form of evidence present at, and relevant in, many types of crime scenes and scenarios. Are we to simply ignore hairs as an evidence type? This book outlines the case for hair evidence’s continued relevance as a valuable biological source that can contribute to assisting in answering questions of identity and questions of what happened or the criminalistic potential of hairs. The authors present a four-level approach to the case management of recovered hairs. This system, which can be incorporated into contemporary forensic practice, stresses the need for thorough and systematic recording of hairs and their microscopic features and on the need to focus on differences to effectively triage recovered hairs. The approach focuses on the efficient and accurate selection of hairs for nuclear and mitochondrial DNA analysis while addressing the criminalistic potential of hairs. Key Features: Outlines the latest advances in the collection and forensic hair fibres, and includes full-colour illustrative figures throughout. Covers the advances in DNA extraction and analysis of hair samples including nuclear and mt-DNA testing. Addresses all forensic aspects of hair evidence including recovery, collection, examination, analysis, testing and presentation of such results in court. A Practical Guide to the Forensic Examination of Hair is a practical reference written for practitioners and promotes the need for quality assurance measures, process standardization and proficiency testing to ensure the scientific reliability of hair examination. The book discusses how to interpret and report on hair findings to impart to investigators, and to the broader legal system, the appropriate weight that should be attributed to hair findings. It provides invaluable methodologies and guidelines that reinforce the ongoing value and validity of hair examinations.

The examination of human hairs in the forensic science setting is a highly specialist forensic discipline. To date the topic has not been covered in a single volume in which all aspects of hair examination are brought together. In this volume an international group of authors have dealt with all aspects of the examination of human hair. The volume

This Second Edition of the best-selling Introduction to Forensic Science and Criminalistics presents the practice of forensic science from a broad viewpoint. The book has been developed to serve as an introductory textbook for courses at the undergraduate level—for both majors and non-majors—to provide students with a working understanding of forensic science. The Second Edition is fully updated to cover the latest scientific methods of evidence collection, evidence analytic techniques, and the application of the analysis results to an investigation and use in court. This includes coverage of physical evidence, evidence collection, crime scene processing, pattern evidence, fingerprint evidence, questioned documents, DNA and biological evidence, drug evidence, toolmarks and fireams, arson and explosives, chemical testing, and a new chapter of computer and digital forensic evidence. Chapters address crime scene evidence, laboratory procedures, emergency technologies, as well as an adjudication of both criminal and civil cases utilizing the evidence. All coverage has been fully updated in all areas that have advanced since the publication of the last edition. Features include: Progresses from introductory concepts—of the legal system and crime scene concepts—to DNA, forensic biology, chemistry, and laboratory principles Introduces students to the scientific method and the application of it to the analysis to various types, and classifications, of forensic evidence The authors’ 90-plus years of real-world police, investigative, and forensic science laboratory experience is brought to bear on the application of forensic science to the investigation and prosecution of cases Addresses the latest developments and advances in forensic sciences, particularly in evidence collection Offers a full complement of instructor's resources to qualifying professors Includes full pedagogy—including learning objectives, key terms, end-of-chapter questions, and boxed case examples—to encourage classroom learning and retention Introduction to Forensic Science and Criminalistics, Second Edition, will serve as an invaluable resource for students in their quest to understand the application of science, and the scientific method, to various forensic disciplines in the pursuit of law and justice through the court system. An Instructor’s Manual with Test Bank and Chapter PowerPoint® slides are available upon qualified course adoption.

Chapter 5 provides guidance to the forensic document examiner by suggesting appropriate methodologies involving a stamp to an impression comparison or an impression-to-impression comparison. Chapter 6 discusses the various techniques available in photographing a stamp die or the impression. Chapter 7 provides a thorough discussion of stamp inks and pigments. Finally, a helpful appendix offers quick reference charts, human resources in the stamp industry, and a very complete glossary. The book contains 345 helpful illustrations of stamps, seals, dies, molds, and impressions. This unique and comprehensive book can be used as both an instructional guide and a reference text by the forensic document examiner when confronted with virtually any case involving a stamp, stamp impression, seal, or seal embossment."--BOOK JACKET.

Crime Reconstruction, Second Edition is an updated guide to the interpretation of physical evidence, written for the advanced student of forensic science, the practicing forensic generalist and those with multiple forensic specialists. It is designed to assist reconstructionists with understanding their role in the justice system; the development and refinement of case theory’ and the limits of physical evidence interpretation. Chisum and Turvey begin with chapters on the history and ethics of crime reconstruction and then shift to the more applied subjects of reconstruction methodology and practice standards. The volume concludes with chapters on courtroom conduct and evidence admissibility to prepare forensic reconstructionists for what awaits them when they take the witness stand. Crime Reconstruction, Second Edition, remains an unparalleled watershed collaborative effort by internationally known, qualified, and respected forensic science practitioner holding generations of case experience among them.
