Using DNA to Solve Cold Cases by U.s. Department of Justice Pdf
In 1995, the National Institute of Justice (NIJ) began research that would attempt to identify how often DNA had exonerated wrongfully convicted defendants. After extensive study, NIJ published the report Convicted by Juries, Exonerated by Science: Case Studies in the Use of DNA Evidence to Establish Innocence After Trial, which presents case studies of 28 inmates for whom DNA analysis was exculpatory.
Shortlisted for The Brass Knuckles Award for Best Nonfiction Crime Book, Crime Writers of Canada Awards Get inside the mind of an elite cold case investigator and learn how to solve a murder. Despite advances in DNA evidence and forensic analysis, almost half of murder cases in Canada and the US remain unsolved.

Solving Cold Cases by Joe D. Kennedy,Hogan Hilling Pdf
Solving a cold case is extremely difficult and many are left unresolved. In this book, retired NCIS Special Agent Joe Kennedy details the methodology he created to solve cold case murders. He offers an in-depth, behind-the-scenes look into why cases go cold, how they are investigated and what is needed to successfully resolve them. Author Kennedy shares his motivations and the lessons he has learned while solving these challenging cases. Also examined are cold cases where other detectives have successfully implemented Kennedy's methodology. Many books delve into the perspectives of criminals who commit murder, but this text takes a fascinating gumshoe journey into the mind of a cold case detective and his passionate search for the truth. Helping law enforcement solve cold cases brings justice and resolution for the victims and their families, and this book provides detectives and true crime enthusiasts the tools to investigate cold cases in their own communities.
A crime historian explores groundbreaking cold-case investigations, the advent of DNA evidence, and its role in long-delayed convictions and exonerations. When geneticist, Professor Alec Jeffreys worked with Leicestershire police on the 1986 case against Colin Pitchfork—the first person convicted of murder based on DNA evidence—a revolution started in the application of forensic expertise. Since then there have been several major cases in which long-standing murders and rapes have been revisited by teams of cold case detectives. Armed with DNA sampling, they have changed the landscape of criminal investigation, as well as the fates of those who thought they could get away with murder, and those who were wrongly convicted. From initial and intensive DNA lab work to the final serving of justice, true crime historian Stephen Wade examines some of the most high-profile cases of recent years: the controversial suspect in the murder of Rachel Nickell in London; the unsolved slayings of schoolchildren Keith Lyon and Lesley Molseed; the notorious World’s End pub killings; the erroneous charges against the “Cardiff Three”; the fate of Sean Hodgson, subject of one of the greatest miscarriages of justice in English history; and many more.
“Thought-provoking true-crime thriller…the book raises urgent questions of balancing public and private good that we’ll likely be dealing with as long as the title implies.”—Wall Street Journal A relentless detective and a civilian genealogist solve a haunting cold case—and launch a crime-fighting revolution that tests the fragile line between justice and privacy. In November 1987, a young couple from the idyllic suburbs of Vancouver Island on an overnight trip to Seattle vanished without a trace. A week later, the bodies of Tanya Van Cuylenborg and her boyfriend Jay Cook were found in rural Washington. It was a brutal crime, and it was the perfect crime: With few clues and no witnesses in the vast and foreboding Olympic Peninsula, an international manhunt turned up empty, and the sensational case that shocked the Pacific Northwest gradually slipped from the headlines. In deep-freeze, long-term storage, biological evidence from the crime sat waiting, as Detective Jim Scharf poured over old case files looking for clues his predecessors missed. Meanwhile, 1,200 miles away in California, CeCe Moore began her lifelong fascination with genetic genealogy, a powerful forensic tool that emerged not from the crime lab, but through the wildly popular home DNA ancestry tests purchased by more than 40 million Americans. When Scharf decided to send the cold case’s decades-old DNA to Parabon NanoLabs, he hoped he would finally bring closure to the Van Cuylenborg and Cook families. He didn’t know that he and Moore would make history. Genetic genealogy, long the province of family tree hobbyists and adoptees seeking their birth families, has made headlines as a cold case solution machine, capable of exposing the darkest secrets of seemingly upstanding citizens. In the hands of a tenacious detective like Scharf, genetic genealogy has solved one baffling killing after another. But as this crime-fighting technique spreads, its sheer power has sparked a national debate: Can we use DNA to catch the murderers among us, yet still protect our last shred of privacy in the digital age—the right to the very blueprint of who we are?
From the detective who helped catch the Golden State Killer, a memoir about investigating America's toughest cold cases, and the rewards - and toll - of a life spent solving crime.For a decade, from 1973, The Golden State Killer stalked and murdered Californians in the dead of night, leaving entire communities afraid to turn off the lights. Then he vanished, and the case remained unsolved.In 1994, when cold-case investigator Paul Holes came across the old file, he swore he would unmask GSK and finally give these families closure. Twenty-four years later, Holes fulfilled that promise, identifying 73-year-old Joseph J. DeAngelo. Headlines blasted around the world: one of America's most prolific serial killers had been caught.That case launched Paul's career into the stratosphere, turning him into an icon in the true-crime world. But while many know the story of the capture of GSK, until now, no one has truly known the man behind it all.In UNMASKED, Paul takes us through his memories of a storied career and provides an insider account of some of the most notorious cases in contemporary American history, including Laci Peterson's murder and Jaycee Dugard's kidnapping. But this is also a revelatory profile of a complex man and what makes him tick: the drive to find closure for victims and their loved ones; the inability to walk away from a challenge - even at the expense of his own happiness. This is a story about the gritty truth of crime solving when there are no 'case closed' headlines. It is the story of a man and his commitment to his cases, and to the people who might have otherwise been forgotten.

The Evaluation of Forensic DNA Evidence by National Research Council,Division on Earth and Life Studies,Commission on Life Sciences,Committee on DNA Forensic Science: An Update Pdf
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.
