As witnessed in landmark criminal cases, the quality and integrity of bloodstain evidence can be a crucial factor in determining a verdict.

Objective establishment of the truth is the goal of any good crime scene investigator. This demands a consideration of all evidence available using proven scientific methodologies to establish objective snapshots of the crime. The majority of forensic disciplines shed light on thewho of a crime, bloodstain pattern analysis is one of the most imp

The Handbook of Bloodstain Pattern Analysis captures the latest understanding of the science that supports bloodstain pattern analysis (BPA) and includes the results of numerous research studies using modern technologies not found in previously published books. It provides the BPA community with a modern, up-to-date reference and training manual to outline and validate the utility, repeatability, and reliability of BPA science. BPA has recently been presented in the news media as an example of “junk” science used in a handful of cases involving wrongful convictions. However, the reality is that the primary issue for BPA in these wrongful convictions is not the science: it is the result of substandard training and the lack of experience of BPA analysts, prior to beginning casework and testifying in court as experts. As such, this book is written to serve as an essential study guide for analysts preparing to sit for the International Association for Identification (IAI) Bloodstain Pattern Analyst Certification exam. The contents of the book are guided by the ANSI/ASB Standards for a Bloodstain Pattern Analysis Training Program. Each chapter has been written by top experts conversant on the relevant BPA, BPA terminology, forensic science, physics, fluid dynamics, crime scene analysis, education/training, bias, and current relevant legal considerations for use of BPA in court. Handbook of Bloodstain Pattern Analysis is the most up-to-date resource on BPA currently available, providing a definitive training manual for practitioners, and an essential reference for forensic pathologists, police investigators, crime scene investigators, attorneys, and students enrolled in forensic science university courses.

In Bloodstain Pattern Evidence, the concepts introduced in the author's first book, Blood Dynamics, are updated and applied to provide essential answers in the resolution of actual crimes. The book is accessible to all levels of investigators, regardless of academic background, and allows readers to develop a fundamental understanding of the underlying scientific principles behind bloodstain pattern evidence. Bloodstain Pattern Evidence builds on the fundamental ideas brought about by an understanding of Non-Newtonian dynamics, and illustrates through case work the practical forensic science applications of these principles to the analysis of bloodstain patterns. - Extensive case examples provide practical application of essential pattern analysis principles - Extensively illustrated with over 350 photos and line drawings - Takes a unique and scientific approach to bloodstain pattern analysis by exploring the fundamentals of fluid behavior
