Outlining the development of forensics from the 19th century to the present day, this text is broken down by 17 main types of forensics, with cases arranged chronologically within type, including: DNA testing; handwriting analysis; hypnosis; odontology (identifying criminals by the teeth marks they left on their victims) psychological profiling; and other techniques. Included is the story of how forensics experts were able to identify a person with only one thousandth of her body (a few hairs and nail and tooth fragments), and the tale of how a psychological profile helped catch a dangerously insane criminal who drank his victims' blood.
