Color Atlas of Forensic Toolmark Identification

Impression evidence can be broadly defined as the transfer of an object's physical morphology in the form of an imprint onto the surface of softer substance. Forensic Scientists encounter various forms of impression evidence on a routine basis. Focusing on marks made by tools, Color Atlas of Forensic Tool Mark Identification features case studies, color photographs, and useful appendices to enhance understanding. This book covers microscopy and micrometry for tool mark examiners, documentation and evaluation of questioned tool marks, hand and power tools, and statistical approaches. The text also provides a study of locks, including common types, parts, nomenclature, and lock picks.
