DNA has proven to be a powerful tool in the fight against crime. DNA evidence can identify suspects, convict the guilty, and exonerate the innocent. Throughout the Nation, criminal justice professionals are discovering that advancements in DNA technology are breathing new life into old, cold, or unsolved criminal cases. Evidence that was previously unsuitable for DNA testing because a biological sample was too small or degraded may now yield a DNA profile. Development of the Combined DNA Index System (CODIS) at the State and national levels enables law enforcement to aid investigations by effectively and efficiently identifying suspects and linking serial crimes to each other. The National Commission on the Future of DNA Evidence made clear, however, that we must dedicate more resources to empower law enforcement to use this technology quickly and effectively. Using DNA to Solve Cold Cases is intended for use by law enforcement and other criminal justice professionals who have the responsibility for reviewing and investigating unsolved cases. This report will provide basic information to assist agencies in the complex process of case review with a specific emphasis on using DNA evidence to solve previously unsolvable crimes. Although DNA is not the only forensic tool that can be valuable to unsolved case investigations, advancements in DNA technology and the success of DNA database systems have inspired law enforcement agencies throughout the country to reevaluate cold cases for DNA evidence. As law enforcement professionals progress through investigations, however, they should keep in mind the array of other technology advancements, such as improved ballistics and fingerprint databases, which may substantially advance a case beyond its original level.

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.

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.

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.

Nearly 185,000 homicides since 1980 remain unsolved, yet with limited staff and resources, it is no surprise that law enforcement units place the bulk of their efforts on current cases where victims’ family members and the media demand answers. Cold Cases: An Evaluation Model with Follow-up Strategies for Investigators provides a comprehensive roadmap for digging those cold cases out of the file room and getting them resolved. Practical and concise, the book is an invaluable tool for police officers and detectives attempting to solve crimes that would otherwise be forgotten. Evaluating the Case Divided into three sections, the book begins with a historical perspective on how cases get to the point where it appears all investigative leads have been exhausted. It includes a chapter on understanding the process of homicide and those who kill — critical information for the homicide investigator. Next, the authors explain the evaluation model. They demonstrate the key elements of organization, thoroughness, and the value of the scientific method. This section validates theories of the crime, raises evidentiary issues and concerns, addresses the informational and behavioral aspects relative to the crime and the participants in the crime, and documents investigative strategies for future efforts on the case. Investigating and Solving the Crime The third section discusses the investigation that follows the evaluation. The book considers questions investigators must ask, including what should be looked at beyond the case file itself, and how the growth in technology since the date of the incident might provide new opportunities to uncover clues. This section also explores the choice of interview/interrogation techniques based on the behavioral aspects involved. Finally, the authors suggest how investigators can maximize their efforts and obtain not just an arrest, but a conviction. Useful appendices include sample standard operating procedures from three different agencies to use as a guide for setting up a cold case unit and a list of additional resources a department may look to for assistance. By following the cold cases evaluation model in this volume, those charged with resolving long-forgotten crimes can increase their chance of an accurate resolution, or at least be able to say that everything that can be done has been done.

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.
