Uses case studies to examine how investigators collect genetic evidence and discusses how DNA has altered crime-solving and the court system as well as the ethical ramifications of cloning, genetic modification, and the death penalty.

The author works with the full cooperation of all involved parties, and draws on legal files and personal interviews to weave the fascinating, true story of the brutal crime that rocked a community and divided its citizens. In a quiet Louisiana suburb, a woman is bludegeoned to death while she sleeps. Her husband is convicted of the murder. But is he really guilty?

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.

Edgar Award winner Thomas H. Cook has earned acclaim and a growing legion of fans for his brilliantly styled, intensely evocative thrillers. Now, in his most seductive suspense novel yet, he draws us into a world of love, betrayal, and murder from which one man can find no escape. "It's better to know, don't you think?... No matter what the cost?" Forty years ago in Sequoyah, Georgia, Charles Overton was sentenced to die for the murder of a young woman, even though her body was never found. But the prosecution had all the ammunition it needed: a blood-stained dress and a jury out for vengeance.... Now true-crime writer Jackson Kinley is coming home to grieve for an old friend. But Sequoyah sheriff Ray Tindall's death has left many questions: Why had he reopened the Overton case... and then, without explanation, shut it down? What was he looking for? And what did he find that he couldn't bear to reveal? The search for answers leads Kinley into a small-town web of corruption, secrecy, and lies--and finally into the darkest corners of the human heart, where the terrible truth lies...in the Evidence of Blood.

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.

Describes how blood analysis is used to solve crimes, including the tests performed by lab technicians on samples to determine blood type and other characteristics, and finding, saving and interpreting blood evidence.
