Lee Harvey Oswald. Samuel Sheppard. O. J. Simpson. The infamous cases surrounding these individuals seem to be forever clouded by doubt and suspicion. They are among the many cases from around the globe that resist a satisfyingly scientific conclusion and, to some, remain more open than shut. In A Question of Evidence, the author of The Casebook of Forensic Detection details some of the most vexing forensic controversies of all time. From the Turin Shroud to the death of Napoleon Bonaparte to the assassination of JFK, Colin Evans lays out the conflicting medical and scientific evidence of each case and shows how it was used or mishandled in reaching a verdict. You'll discover why even the most efficient crime lab and expert testimony can still fail to resolve a difficult case to everyone's complete satisfaction. As absorbing and suspenseful as the most gripping mystery novel, A Question of Evidence will have you pondering the verdicts long after the last gavel comes down.Evans, Colin is the author of 'Question of Evidence The Casebook of Great Forensic Controversies, from Napoleon to O. J.' with ISBN 9780471440147 and ISBN 0471440140.
