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 opens with the basic foundation accidence covering the physiology, growth and structure of hair. Forensic specific aspects of hair structure are then dealt with and a protocol for examination is presented. The remaining chapters deal with non microscopy approaches to hair examination covering historical and contemporary knowledge. These chapters include biochemical approaches to hair examination,
Forensic Microscopy: A Laboratory Manual will provide the student with a practical overview and understanding of the various microscopes and microscopic techniques employed within the field of forensic science. Each laboratory experiment has been carefully designed to cover the variety of evidence disciplines within the forensic science field with carefully set out objectives, explanations of each topic and worksheets to help students compile and analyse their results. The emphasis is placed on the practical aspects of the analysis to enrich student understanding through hands on experience. The experiments move from basic through to specialised and have been developed to cover a variety of evidence disciplines within forensic science field. The emphasis is placed on techniques currently used by trace examiners. This unique, forensic focused, microscopy laboratory manual provides objectives for each topic covered with experiments designed to reinforce what has been learnt along with end of chapter questions, report requirements and numerous references for further reading. Impression evidence such as fingerprints, shoe tread patterns, tool marks and firearms will be analysed using simple stereomicroscopic techniques. Body fluids drug and trace evidence (e.g. paint glass hair fibre) will be covered by a variety of microscopes and specialized microscopic techniques.

Every action performed by a crime scene investigator has an underlying purpose: to both recover evidence and capture scene context. It is imperative that crime scene investigators must understand their mandate—not only as an essential function of their job but because they have the immense responsibility and duty to do so. Practice Crime Scene Processing and Investigation, Third Edition provides the essential tools for what crime scene investigators need to know, what they need to do, and how to do it. As professionals, any investigator’s master is the truth and only the truth. Professional ethics demands an absolute adherence to this mandate. When investigators can effectively seek, collect, and preserve information and evidence from the crime scene to the justice system—doing so without any agenda beyond seeking the truth— not only are they carrying out the essential function and duty of their job, it also increases the likelihood that the ultimate goal of true justice will be served. Richly illustrated—with more than 415 figures, including over 300 color photographs—the Third Edition of this best-seller thoroughly addresses the role of the crime scene investigator in the context of: Understanding the nature of physical evidence, including fingerprint, biological, trace, hair and fiber, impression, and other forms of evidence Assessing the scene, including search considerations and dealing with chemical and bioterror hazards Crime scene photography; scene sketching, mapping, and documentation; and the role of crime scene analysis and reconstruction Bloodstain pattern analysis and discussion of the body as a crime scene Special scene considerations, including fire, buried bodies, and entomological evidence Coverage details the importance of maintaining objectivity, emphasizing that every action the crime scene investigator performs has an underlying purpose: to both recover evidence and capture scene context. Key features: Outlines the responsibilities of the responding officer, from documenting and securing the initial information to providing emergency care Includes three new chapters on light technology and crime scene processing techniques, recovering fingerprints, and castings Addresses emerging technology and new techniques in 3-D Laser scanning procedures in capturing a scene Provides a list of review questions at the end of each chapter Practice Crime Scene Processing and Investigation, Third Edition includes practical, proven methods to be used at any crime scene to ensure that evidence is preserved, admissible in court, and persuasive. Course ancillaries including PowerPoint® lecture slides and a Test Bank are available with qualified course adoption.
Television shows like CSI, Forensic Files, and The New Detectives make it look so easy. A crime-scene photographer snaps photographs, a fingerprint technician examines a gun, uniformed officers seal off a house while detectives gather hair and blood samples, placing them carefully into separate evidence containers. In a crime laboratory, a suspect's hands are meticulously examined for gunshot residue. An autopsy is performed in order to determine range and angle of the gunshot and time-of-death evidence. Dozens of tests and analyses are performed and cross-referenced. A conviction is made. Another crime is solved. The credits roll. The American public has become captivated by success stories like this one with their satisfyingly definitive conclusions, all made possible because of the wonders of forensic science. Unfortunately, however, popular television dramas do not represent the way most homicide cases in the United States are actually handled. Crime scenes are not always protected from contamination; physical evidence is often packaged improperly, lost, or left unaccounted for; forensic experts are not always consulted; and mistakes and omissions on the autopsy table frequently cut investigations short or send detectives down the wrong investigative path. In Forensics Under Fire, Jim Fisher makes a compelling case that these and other problems in the practice of forensic science allow offenders to escape justice and can also lead to the imprisonment of innocent people. Bringing together examples from a host of high-profile criminal cases and familiar figures, such as the JonBenet Ramsey case and Dr. Henry Lee who presented physical evidence in the O. J. Simpson trial, along with many lesser known but fascinating stories, Fisher presents daunting evidence that forensic science has a long way to go before it lives up to its potential and the public's expectations.
