Crime scene reconstruction (CSR) is today’s hot topic. The immense proliferation of television, print, and electronic media directed at this area has generated significant public interest, albeit occasionally encouraging inaccurate perceptions. Practical Crime Scene Analysis and Reconstruction bridges the gap between perception and reality, helping readers understand the nature of the scientific method and teaching the proper application of its components.A proven methodology The book begins by recounting the history of crime scene analysis and exploring fundamental principles. Then the authors introduce their proven methodology, known as Event Analysis. This technique defines specific actions, discusses the order of those actions, and offers significant insight into determining what did or did not happen in the course of the incident under investigation. Using case studies and more than 200 color photos, the book demonstrates this method and how it can be used to explain clues that would otherwise be puzzling or ambiguous. Practical advice from the crime scene to the courtroomThe authors show how to resolve significant questions that arise in the course of CSR through the use of an event analysis worksheet. The book also discusses crime scene protocol, bloodstain pattern analysis, gunshot investigation, and forensic pathology and the human body. The final chapters provide instruction on writing crime scene reports, discuss ethical issues, and give advice on courtroom presentation.Includes color photos demonstrating the science of CSR on: SuperpositionTiming and sequenceBloodstain analysisBallisticsWound patterns

The book, which features several detailed illustrations and photographs, also includes a new method for Palmar Flexion Crease Identification (palm lines) designed by the author and which has helped solve several criminal cases where fingerprints were not available. For crime scene technicians, forensic identification specialists, or anyone else pursuing a career in forensic science, this book is arguably the definitive source in the science of friction ridge identification.

This book covers Munchausen and Munchausen by Proxy (MBP) though the terms have recently changed. The 2013 DSM-V—the update to the American Psychiatric Association's (APA) diagnostic and classification tool—has classified both Munchausen and MBP as "Factitious Systematic Abuse."

Many involve repeat and long-term instances of hospital and medical fraud. This book covers the syndrome itself, interviewing and investigative aspects, victimology, as well indicators in the event of homicide and death.
