Bloodstain evidence has become a deciding factor in the outcome of many of the world's most notorious criminal cases. As a result, substantiation of this evidence is crucial to those on either side of the courtroom aisle. The challenge is to obtain an authoritative reference that provides the latest information in a comprehensive and effective manner. Principles of Bloodstain Pattern Analysis: Theory and Practice presents an in-depth investigation of this important subject matter. A multidisciplinary approach is presented throughout the book that uses scene and laboratory examinations in conjunction with forensic pathology, forensic serology, and chemical enhancement techniques. Emphasis is on a thought process based on taxonomic classification of bloodstains that takes into account their physical characteristics of size, shape, and distribution, and the specific mechanisms that produce them. Individual chapters analyze case studies, with two chapters specifically discussing the details of legal issues as they pertain to bloodstain pattern analysis. Information highlighted throughout the book includes an examination of bloodstained clothing and footwear and information on bloodstain interpretation for crime scene reconstruction.
