This exciting true-crime compendium brings together the details of a range of more than 50 challenging criminal cases that were either only recently solved or remain unsolved despite intensive investigations and appeals to the public. Many investigations end up as 'cold cases' when files are closed, but DNA advances and other new forensic technologies are causing more and more dormant files to be reopened. DNA has also overturned many guilty verdicts, and each time a prisoner has his or her conviction quashed, another unsolved crime is created.Famous Cold Cases presents each case in a dossier format that describes the crime and lays out the clues collected by investigators. Each chapter concentrates on a specific criminal activity and has numerous vivid case examples arranged chronologically and boxes highlighting famous cases, techniques used to solve them, why the trails went cold - and how, in some cases, the crime was solved. From murders and assassinations to kidnappings, robberies and fraud, Famous Cold Cases invites the reader to review each case, analyze the evidence and arrive at the most probable solution.
