In Blood Evidence Dr. Henry Lee and Frank Tirnady lift the yellow caution tape at the crime scene and show first-hand how investigators can collect genetic evidence off everything from blood stains to cigarette butts. More than just case histories, this book examines how DNA has altered not only the way we solve crimes and how courts evaluate evidence, but also the ethical implications of cloning, genetic modifications, and the death penalty.
In addition to covering the current state-of-the-art techniques in DNA interpretation, Lee and Tirnady cover the evolution of this burgeoning science from Sir Alec Jeffrey's discovery of DNA fingerprinting and its use in the Pitchfork case to the recent attempts to trace deadly Anthrax strains and rogue genetically-modified corn to their source through genetic markers. Along the way they introduce several of the scientists responsible for bringing about this revolution in crime fighting as well as a collection of fascinating stories of investigators who use traces of DNA from baseball caps, bones, clothes and even cat fur to solve seemingly impossible cases. Filled with descriptions of the groundbreaking events that helped advance this new science, Blood Evidence offers an accessible, yet detailed explanation of the science behind some of today's most noteworthy (and infamous) cases.
