The analysis of bloodstain patterns is commonplace in violent crime investigations. Bloodstain patterns can provide a great deal of information to the investigator and crime scene reconstructionist, yet confusion, ambiguity and a certain amount of controversy prevent full acceptance by the scientific and legal communities. All present 'blood spatter' data were compiled in the 1920s, before non-Newtonian fluid behaviour was described. Medical and clinical research, which receives more adequate funding than forensic research, is providing a growing body of information on blood composition and behaviour. Those applying bloodstain pattern analysis have, until now, ignored this reference material in favour of historical studies. As early as 1951, Paul Kirk promoted bloodstain pattern interpretation as a scientific discipline. Since his death in 1970, use of bloodstain pattern interpretation has increased markedly, yet the technical foundations have changed little. Information unknown during Dr Kirk's studies has yet to be incorporated into the literature on blood distribution behaviour. This book aims to do that, with the benefit of the author's 25 years of research into forensic bloodstain interpretation.

Physical evidence has become increasingly important in criminal investigation. The author suggests such evidence must be examined and its meaning interpreted by the forensic scientist. The scene examiner must first, however, recognise then collect and preserve the physical evidence in accordance with the requirements of science and the law. Properly obtained and examined, physical evidence can answer such questions as "How was the crime committed?" In this book MacDonnell illustrates how blood-spatter patterns can reveal the way events unfolded while the crime was being committed. He goes on to explain the scientific basis of bloodstain pattern examinations and gives examples of how such evidence helped the criminal investigator.

This book brings together two important areas of forensic science evidence which are often examined by the same forensic scientist in the working laboratory. Following an introductory chapter on trace evidence analysis, the book goes on to cover the manufacturing processes of glass and paint before discussing analytical techniques and methods for interpreting the data. The chapters on glass cover microscopic and elemental analysis, statistical methods of analysing evidence and the interpretation of the physical phenomena that occur when glass breaks under varying conditions. Chapters on paint cover analytical techniques based on colour analysis, pyrolysis, infrared spectroscopy, scanning electron microscopy and X-ray methods. This section culminates in a chapter on the interpretation of paint evidence. This book is essential reading for students studying the forensic sciences and for lawyers, police officers and other readers who wish to understand the nature of glass and paint evidence analysis.

The forensic examination of human hair is a highly specialist discipline, which still attracts its share if debate and controversy. This book brings together the latest findings, beginning with the physiology and growth of human hair, and going on to the microscopic examination, DNA typing from hair samples, elemental analysis, examination of cosmetic treatments and an assessment of the evidential value and interpretation of hairs as evidence. Contributions have come from an international panel of distinguished forensic scientists and this book will be essential reading for students of forensic science. It will also benefit those in the legal profession and law enforcement agencies, who need a basic understanding of the subject.

This book presents a collection of intriguing case studies that demonstrate how these small pieces of evidence can tell the biggest stories, and provide a link between suspects, victims, and crime scenes. Each chapter presents a case review (particularly one where DNA evidence was not available, or was inconclusive), follows the progress of the investigation, and describes how trace evidence assisted. Written by the actual investigators involved, each chapter also highlights some important aspect of trace evidence analysis, such as instrumentation, sampling methods, interpretation, significance, research to answer a case-related question, or a manufacturing process. The chapters are self-contained and written for both technical expert and layperson alike. This book will be of interest to trace analysts and other forensic scientists, law enforcement officers and investigators, lawyers and students of related fields.
