Matching DNA samples from crime scenes and suspects is rapidly becoming a key source of evidence for use in our justice system. DNA Technology in Forensic Science offers recommendations for resolving crucial questions that are emerging as DNA typing becomes more widespread. The volume addresses key issues: Quality and reliability in DNA typing, including the introduction of new technologies, problems of standardization, and approaches to certification. DNA typing in the courtroom, including issues of population genetics, levels of understanding among judges and juries, and admissibility. Societal issues, such as privacy of DNA data, storage of samples and data, and the rights of defendants to quality testing technology. Combining this original volume with the new update-The Evaluation of Forensic DNA Evidence-provides the complete, up-to-date picture of this highly important and visible topic. This volume offers important guidance to anyone working with this emerging law enforcement tool: policymakers, specialists in criminal law, forensic scientists, geneticists, researchers, faculty, and students.

This state-of-the-art collection of easily reproducible methods includes all of the major techniques of DNA analysis currently used in forensic identity testing. The methods include the recovery of DNA from a large range of sample types, analysis of DNA as single and multi-locus VNTR probes, PCR amplification of STR and other loci, and mitochondrial sequencing. The expert scientists writing here -- many from laboratories around the world -- also discuss how to interpret the results in cases of unknown identity and disputed parentage.-- Covers all steps from extraction of human DNA through to analysis and interpretation-- Takes advantage of new methodologies such as capillary electrophoresis-- Clear step-by-step instructions ensure unfailing reproducibility.

This reference book comprehensively reviews the significance of DNA technology in forensic science. After presenting the theory, basic principles, tools and techniques that are used in forensic DNA typing, it summarizes various techniques, including autosomal STR, Y-STR, X-STR, mitochondrial DNA and NGS, used in solving both criminal as and civil cases, such as paternity disputes, identification of mutilated remains, and culprit identification in sexual assault and murder cases. It also provides an overview of DNA-based genetic diagnostics for various diseases, and discusses the role of DNA typing in drug reactions, as well as the application of non-human DNA profiling of animals and plants in forensic science investigations. Lastly, the book examines the role of internal quality control in maintaining the high quality of DNA profiling.

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.

DNA profiling—commonly known as DNA fingerprinting—is often heralded as unassailable criminal evidence, a veritable “truth machine” that can overturn convictions based on eyewitness testimony, confessions, and other forms of forensic evidence. But DNA evidence is far from infallible. Truth Machine traces the controversial history of DNA fingerprinting by looking at court cases in the United States and United Kingdom beginning in the mid-1980s, when the practice was invented, and continuing until the present. Ultimately, Truth Machine presents compelling evidence of the obstacles and opportunities at the intersection of science, technology, sociology, and law.

This manual presents practical approaches to using DNA fingerprinting and genetic profiling to answer a variety of biological and medical questions. It provides detailed methodology for setting up and performing experiments and evaluating results. Extensive troubleshooting tips, helpful hints, and advice for daily practice are also included. This will be a useful guide for scientists and researchers engaged in genetic identification and relationship analyses.

When DNA profiling was first introduced into the American legal system in 1987, it was heralded as a technology that would revolutionize law enforcement. As an investigative tool, it has lived up to much of this hype—it is regularly used to track down unknown criminals, put murderers and rapists behind bars, and exonerate the innocent. Yet, this promise took ten turbulent years to be fulfilled. In Genetic Witness, Jay D. Aronson uncovers the dramatic early history of DNA profiling that has been obscured by the technique’s recent success. He demonstrates that robust quality control and quality assurance measures were initially nonexistent, interpretation of test results was based more on assumption than empirical evidence, and the technique was susceptible to error at every stage. Most of these issues came to light only through defense challenges to what prosecutors claimed to be an infallible technology. Although this process was fraught with controversy, inefficiency, and personal antagonism, the quality of DNA evidence improved dramatically as a result. Aronson argues, however, that the dream of a perfect identification technology remains unrealized.
