To take a crime from scene to court may involve several specialized branches of forensic science. Criminalistics specialists look at statistics, splash patterns, fingerprints and distribution of material at the scene; forensic chemistry deals with fires, explosives, glass, paint and soil analysis; toxicology looks at poisons and drug abuse; serology is the science of body fluids including blood, saliva and semen; the documents unit look at fakes and forgeries; and the computer branch investigate hacking and electronically detectable crimes. This case-packed book shows you how each unit works through 50 carefully selected crime studies that describe how scientific methods have been used within the field of criminal investigation across the world.
