| forensic science hair analysis: Strengthening Forensic Science in the United States National Research Council, Division on Engineering and Physical Sciences, Committee on Applied and Theoretical Statistics, Policy and Global Affairs, Committee on Science, Technology, and Law, Committee on Identifying the Needs of the Forensic Sciences Community, 2009-07-29 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. |

| forensic science hair analysis: A Practical Guide to the Forensic Examination of Hair James Robertson, Elizabeth Brooks, 2021-10-21 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.

| forensic science hair analysis: Inside the Cell Erin E Murphy, 2015-10-06 Josiah Sutton was convicted of rape. He was five inches shorter and 65 pounds lighter than the suspect described by the victim, but at trial a lab analyst testified that his DNA was found at the crime scene. His case looked like many others -- arrest, swab, match, conviction. But there was just one problem -- Sutton was innocent. We think of DNA forensics as an infallible science that catches the bad guys and exonerates the innocent. But when the science goes rogue, it can lead to a gross miscarriage of justice. Erin Murphy exposes the dark side of forensic DNA testing: crime labs that receive little oversight and produce inconsistent results; prosecutors who push to test smaller and poorer-quality samples, inviting error and bias; law-enforcement officers who compile massive, unregulated, and racially skewed DNA databases; and industry lobbyists who push policies of stop and spit. DNA testing is rightly seen as a transformative technological breakthrough, but we should be wary of placing such a powerful weapon in the hands of the same broken criminal justice system that has produced mass incarceration, privileged government interests over personal privacy, and all too often enforced the law in a biased or unjust manner. Inside the Cell exposes the truth about forensic DNA, and shows us what it will take to harness the power of genetic identification in service of accuracy and fairness. |

| forensic science hair analysis: Autopsy of a Crime Lab Brandon L. Garrett, 2021-03-23 This book exposes the dangerously imperfect forensic evidence that we rely on for criminal convictions. That's not my fingerprint, your honor, said the defendant, after FBI experts reported a 100-percent identification. The FBI was wrong. It is shocking how often they are. Autopsy of a Crime Lab is the first book to catalog the sources of error and the faulty science behind a range of well-known forensic evidence, from fingerprints and firearms to forensic algorithms. In this devastating forensic takedown, noted legal expert Brandon L. Garrett poses the questions that should be asked in courtrooms every day: Where are the studies that validate the basic premises of widely accepted techniques such as fingerprinting? How can experts testify with 100-percent certainty about a fingerprint, when there is no such thing as a 100 percent match? Where is the quality control at the crime scenes and in the laboratories? Should we so readily adopt powerful new technologies like facial recognition software and rapid DNA machines? And why have judges been so reluctant to consider the weaknesses of so many long-accepted methods? Taking us into the lives of the wrongfully convicted or nearly convicted, into crime labs rocked by scandal, and onto the front lines of promising reform efforts driven by professionals and researchers alike, Autopsy of a Crime Lab illustrates the persistence and perniciousness of shaky science and its well-meaning practitioners. |

| forensic science hair analysis: The Evaluation of Forensic DNA Evidence National Research Council, Division on Earth and Life Studies, Commission on Life Sciences, Committee on DNA Forensic Science: An Update, 1996-12-12 In 1992 the National Research Council issued DNA Technology in Forensic Science, a book that documented the state of the art in this emerging field. Recently, this volume was brought to worldwide attention in the murder trial of celebrity O. J. Simpson. The Evaluation of Forensic DNA Evidence reports on developments in population genetics and statistics since the original volume was published. The committee comments on statements in the original book that proved controversial or that have been misapplied in the courts. This volume offers recommendations for handling DNA samples, performing calculations, and other aspects of using DNA as a forensic toolâ€modifying some recommendations presented in the 1992 volume. The update addresses two major areas: Determination of DNA profiles. The committee considers how laboratory errors (particularly false matches) can arise, how errors might be reduced, and how to take into account the fact that the error rate can never be reduced to zero. Interpretation of a finding that the DNA profile of a suspect or victim matches the evidence DNA. The committee addresses controversies in population genetics, exploring the problems that arise from the mixture of groups and subgroups in the American population and how this substructure can be accounted for in calculating frequencies. This volume examines statistical issues in interpreting frequencies as probabilities, including adjustments when a suspect is found through a database search. The committee includes a detailed discussion of what its recommendations would mean in the courtroom, with numerous case citations. By resolving several remaining issues in the evaluation of this increasingly important area of forensic evidence, this technical update will be important to forensic scientists and population geneticistsâ€and helpful to attorneys, judges, and others who need to understand DNA and the law. Anyone working in laboratories and in the courts or anyone studying this issue should own this book. |

| forensic science hair analysis: Blood, Powder, and Residue Beth A. Bechky, 2021-01-19 A rare behind-the-scenes look at the work of forensic scientists The findings of forensic science—from DNA profiles and chemical identifications of illegal drugs to comparisons of bullets, fingerprints, and shoeprints—are widely used in police investigations and courtroom proceedings. While we recognize the significance of this evidence for criminal justice, the actual work of forensic scientists is rarely examined and largely misunderstood. Blood, Powder, and Residue goes inside a metropolitan crime laboratory to shed light on the complex social forces that underlie the analysis of forensic evidence. Drawing on eighteen months of rigorous fieldwork in a crime lab of a major metro area, Beth Bechky tells the stories of the forensic scientists who struggle to deliver unbiased science while under intense pressure from adversarial lawyers, escalating standards of evidence, and critical public scrutiny. Bechky brings to life the daily challenges these scientists face, from the painstaking screening and testing of evidence to making communal decisions about writing up the lab report, all while worrying about attorneys asking them uninformed questions in court. She shows how the work of forensic scientists is fraught with the tensions of serving justice—constantly having to anticipate the expectations of the world of law and the assumptions of the public—while also staying true to their scientific ideals. Blood, Powder, and Residue offers a vivid and sometimes harrowing picture of the lives of highly trained experts tasked with translating their knowledge for others who depend on it to deliver justice. |
| forensic science hair analysis: Tracing Technologies Dr Barbara Prainsack, Professor Helena Machado, 2013-01-28 The real heroes of television crime shows in the twenty-first century are no longer police detectives but forensic technologies. The immense popularity of high-tech crime television shows has changed the way in which crime scene work is viewed. The term 'CSI-effect' was coined to signify a situation where people's views and practices have been influenced by such media representations, e.g. judges and jurors putting more weight on forensic evidence that has been produced with high-tech tools - in particular, DNA evidence - than on other kinds of evidence. While considerable scholarly attention has been paid to examining the CSI effect on publics, jurors, judges, and police investigators, prisoners' views on forensic technologies and policing have been under-explored. Drawing on a research sample of over 50 interviews carried out with prisoners in Portugal and Austria, this groundbreaking book shows how prisoners view crime scene traces, how they understand crime scene technologies, and what effect they attribute to the existence of large police databases on their own lives, careers, and futures. Through critically engaging with STS, sociological and criminological perspectives on the use of DNA technologies within the criminal justice system, this work provides the reader with valuable insights into the effect of different legal, political, discursive, and historical configurations on how crime scene technologies are utilized by the police and related to by convicted offenders. |

The second section examines the collection and preservation of biological evidence under a variety of different circumstances and the identification of human remains—including in mass disaster settings. It discusses applications to bioterrorism investigations, animal DNA testing in criminal cases, pedigree questions and wildlife forensic problems, applications in forensic entomology, and forensic botany. The third section explores recent developments and new technologies, including the rigorous identification of tissue of origin, mtDNA profiling using immobilized probe strips, chips and next-generation sequencing, the use of SNPs to ascertain phenotypic characteristics, and the molecular autopsy that looks at aspects of toxicogenetics and pharmacogenetics. The book concludes with a discussion on law, ethics, and policy. It examines the use of DNA evidence in the criminal justice system in both the United States and Europe, ethical issues in forensic laboratory practices, familial searches, DNA databases, ancestry searches, physical phenotyping, and report writing. The contributors also examine DNA applications in immigration and human trafficking cases and international perspectives on DNA databases. |

| forensic science hair analysis: Forensic Gait Analysis Ivan Birch, Michael Nirenberg, Wesley Vernon, Maria Birch, 2020-07-07 Gait analysis is the systematic study of human walking, using the eye and brain of experienced observers, augmented by instrumentation for measuring body movements, body mechanics, and the activity of the muscles. Since Aristotle’s work on gait analysis more than 2000 years ago, it has become an established clinical science used extensively in the healthcare and rehabilitation fields for diagnosis and treatment. Forensic Gait Analysis details the more recent, and rapidly developing, use of gait analysis in the forensic sciences. The book considers the use of observational gait analysis, based on video recordings, to assist in the process of identification or exclusion. With the increase in use of CCTV and surveillance systems over the last 20 to 30 years, there has been a steady and rapid increase in the use of gait as evidence. Currently, gait analysis is widely used in the UK in criminal investigations, with increasing awareness of its potential use in the US, Europe, and globally. The book details the history of the science, current practices, and of the emergent application to establish best-practice standards that conform to those of other forensic science disciplines. Engagement with the Forensic Science Regulator, and the Chartered Society of Forensic Sciences in the UK, and the International Association for Identification has helped to ensure and enhance the quality assurance of forensic gait analysis. However, there remains a fundamental lack of standardized training and methodology for use in evidentiary and investigative casework. This book fills that void, serving as one of the first to describe the current state of practice, capabilities and limitations, and to outline methods, standards of practice and expectations of the gait analyst as a forensic practitioner. Forensic Gait Analysis reflects current research and forensic practice and will serve as a state-of-the-art guide to the use of gait analysis in the forensic context—for both education and training purposes. It will be a welcome addition to the libraries of professionals in the areas of podiatry, gait analysis, forensic video analysis, law enforcement, and legal practice. |

| forensic science hair analysis: Drugs of Abuse Raphael C. Wong, Harley Y. Tse, 2007-11-05 A comprehensive review of the science of drug testing in all its aspects, placing emphasis on technologies that use body fluids other than urine for determining the presence of drugs of abuse. The authors discuss the various body fluid specimens suitable for testing for illicit drugs-particularly saliva, sweat, and hair-describe the structural and manufacturing aspects of on-site testing devices based on lateral flow immunoassay, and detail the pitfalls of using these specimens. They also discuss in detail the problem of sample adulteration and its detection. Since oral fluid has the best potential of succeeding urine as the next matrix of choice for drug detection, four popular saliva testing devices are examined: Intercept®, the Drager Drug Test®, Oratect®, and Drugwipe. Political, social, and legal issues are also considered in articles on privacy, the use of drug testing in courts, and the problem of sample adulteration. |
| forensic science hair analysis: The Silent Patient Alex Michaelides, 2019-02-05 **THE INSTANT #1 NEW YORK TIMES BESTSELLER** An unforgettable—and Hollywood-bound—new thriller... A mix of Hitchcockian suspense, Agatha Christie plotting, and Greek tragedy. —Entertainment Weekly The Silent Patient is a shocking psychological thriller of a woman’s act of violence against her husband—and of the therapist obsessed with uncovering her motive. Alicia Berenson’s life is seemingly perfect. A famous painter married to an in-demand fashion photographer, she lives in a grand house with big windows overlooking a park in one of London’s most desirable areas. One evening her husband Gabriel returns home late from a fashion shoot, and Alicia shoots him five times in the face, and then never speaks another word. Alicia’s refusal to talk, or give any kind of explanation, turns a domestic tragedy into something far grander, a mystery that captures the public imagination and casts Alicia into notoriety. The price of her art skyrockets, and she, the silent patient, is hidden away from the tabloids and spotlight at the Grove, a secure forensic unit in North London. Theo Faber is a criminal psychotherapist who has waited a long time for the opportunity to work with Alicia. His determination to get her to talk and unravel the mystery of why she shot her husband takes him down a twisting path into his own motivations—a search for the truth that threatens to consume him.... |
