Hidden Evidence takes you to the scenes of 40 infamous crimes and into the heart of the forensic investigations. These are the true crime shockers that have grabbed headlines and aroused public passions. David Owen explains the scientific procedures that helped crack every one of these cases -- from the gathering of elusive physical clues to the examination of weapons and bodies, to the use of sophisticated scientific analysis. Threaded throughout the book is the history of forensic science and the technologies that support it, including: fingerprinting, autopsies, handwriting analysis, ballistics, hair sampling, blood typing, DNA testing, dental records, gas chromatography, mass spectrometry, compound and electron microscopes, and toxicology.
