Forensic science has helped bring to justice some of the most evil, devious, and dangerous criminals in history. Using advanced technology, dogged research and intelligent analysis, forensic scientists can follow a trail of DNA, fingerprints, ballistics records, and microscopic fibers directly to a criminal. Featuring accounts of hundreds of real-life crime investigations, and illustrated with more than 450 photographs. Crime Investigation takes a global look at how forensic science has evolved from ancient times to today's sophisticated technologies, including: Infrared spectrometers which can identify the exact nature of clothing fibers left by suspects. CT scanners, used to pinpoint weapons in suitcases. Software programs and specialist modellers able to rebuild a victim's facial features over a bare skull. DNA profiling-a revolutionary tool which has allowed investigators to solve "cold cases" decades old, using evidence based on just a few cells.
