When a crime or other incident takes place, clothing items are often present or left behind, and can become directly involved in the case itself. Items of clothing are thus one of the most common types of exhibit examined in court. They can provide valuable information in cases of violent crimes, such as homicide or rape, as well as in burglary, ro

Knowledge of the science behind fires is critical to understanding a fire’s cause and successfully presenting that determination to the authorities or in litigation. Now in its second edition, Scientific Protocols for Fire Investigation focuses on the practical application of scientific principles to determine the causes of fires. Uniquely qualified with years of experience in on-site investigations, lab analyses, and courtroom presentation, the author provides a resource that is unparalleled in depth and focus. The book explores: The history of fire investigation and the basic chemistry and physics of fire The science of fire dynamics—how things burn and how they interact with their surroundings while doing so Practical procedures for conducting fire scene inspections Laboratory examination of fire debris to test for the presence of ignitable liquid residues and for potential ignition sources Relevant scientific principles as applied to 30 actual fires The evolution of the mythology of arson investigation The common root causes of errors in fire investigation The final chapter discusses the professional practice of fire investigation. It examines quality assurance, business practices, and the fundamentals of being an expert witness, with advice for giving testimony in depositions and at trial. Other highlights of the second edition include new and expanded discussions on novel training methods, first assumptions, computer fire modeling, low voltage ignition sources, the questionable validity of some origin determinations, and recent changes in NFPA 921. Thorough and accessible, this volume not only provides the practical information necessary to conduct an effective inquiry but also offers insight into the science, history, and theory behind what makes fire investigation a multi-faceted profession. John Lentini discusses the book in a video on the CRC Press YouTube Channel.

Scientific Protocols for Fire Investigation, Third Edition focuses on the practical application of fundamental scientific principles to determine the causes of fires. Originally published in 2006, the First Edition was very well received by fire investigators and those who work with them. Since fire investigation is a rapidly evolving field—driven by new discoveries about fire behavior—the Second Edition was published in late 2012. This latest, fully updated Third Edition reflects the most recent developments in the field. Currently, serious research is underway to try to understand the role of ventilation in structure fires. Likewise, there is improved understanding of the kinds of errors investigators can make that lead to incorrect determinations of the causes of fires. In addition to the scientific aspects, the litigation of fire related events is rapidly changing, particularly with respect to an investigator's qualifications to serve as an expert witness. This book covers these latest developments and ties together the changing standards for fire investigations with the fundamental scientific knowledge presented in the early chapters of the book. The book is intended for those individuals who have recently entered the field of fire investigation, and those who are studying fire investigation with a plan to become certified professionals. In addition, professionals in the insurance industry who hire fire investigators will find this an invaluable resource. Insurance companies have sustained significant losses by hiring individuals who are not qualified, resulting in cases being settled or lost at a cost of millions. Insurance adjusters and investigators will learn to recognize quality fire investigations and those that are not up to today's standards. Lastly, this book is also for the many attorneys who litigate fire cases. Written with language and terms that make the science accessible even to the non-scientist, this new edition will be a welcome resource to any professional involved in fire and arson cases.

Forensic DNA Transfer provides a guide to the recognition and current understanding of DNA transfer in forensic criminal investigations. Increased improvements in technology mean that it is now routinely possible to obtain DNA profiles from non-visible deposits. How or when the DNA in question was deposited may be an issue in the context of the case, especially if the donor of the DNA is not in dispute. A DNA profile alone cannot reveal when or how that DNA was deposited at a crime scene, nor can it reveal the body matter from which it originated. Issues of transfer associated with activities may be debated—which the traditional discrimination purpose of DNA profiling cannot address. DNA may be everywhere and anywhere—in homes, at workplaces, during transport, and on personal items including clothing. DNA from a person may be on an object they have never contacted or in a room they have never entered. Concepts discussed in the book include non-self DNA on hands through day-to-day activities, the prevalence of background DNA in the environment and perhaps on the exhibit, the persistence of any DNA transferred, and that a DNA result will depend on these variables as well as recovery techniques. Since DNA may be transferred to an exhibit: (a) during the commission of a crime, (b) before the crime, and/or (c) after the crime through handling, examination, and testing, this book covers various transfer pathways and sources of DNA. Documented cases of inadvertent transfer of DNA resulting in wrongful convictions or the misdirection of criminal investigations are discussed—with an emphasis on contamination mitigation throughout the entire process. Forensic DNA Transfer examines the additional complexity resulting from non-visible deposits of DNA that impact on sampling and testing regimes. The changing understanding of the composition of purported 'touch DNA' deposits from the skin, including extracellular DNA transported via body secretions, is described. Further, the newer focus on interpreting DNA evidence—using activity level propositions and the rationale and associated issues—is also discussed.

The identification and quantification of material present and collected at a crime scene are critical requirements in investigative analyses. Forensic analysts use a variety of tools and techniques to achieve this, many of which use light. Light is not always the forensic analyst’s friend however, as light can degrade samples and alter results. This book details the analysis of a range of molecular systems by light-based techniques relevant to forensic science, as well as the negative effects of light in the degradation of forensic evidence, such as the breakage of DNA linkages during DNA profiling. The introductory chapters explain how chemiluminescence and fluorescence can be used to visualise samples and the advantages and limitations of available technologies. They also discuss the limitations of our knowledge about how light could alter the physical nature of materials, for example by breaking DNA linkages during DNA profiling or by modifying molecular structures of polymers and illicit drugs. The book then explains how to detect, analyse and interpret evidence from materials such as illicit drugs, agents of bioterrorism, and textiles, using light-based techniques from microscopy to surface enhanced Raman spectroscopy. Edited by active photobiological and forensic scientists, this book will be of interest to students and researchers in the fields of photochemistry, photobiology, toxicology and forensic science.

This book, the second volume of Crime Scene Management in Forensic Sciences, reviews the role and impact of forensic evidence in criminal investigations. It also addresses the importance of post mortem examination in criminal cases. The book investigates the use of insects and arthropods to estimate post mortem intervals during forensic investigations. Further, it discusses the physiological effects of xenobiotics at the time of death, based on their concentration and distribution in the body at autopsy. Importantly, it also discusses digital forensic investigation, which can be used for the analysis of digital evidence produced at a court of law. Lastly, it defines the structure and legal framework of these forensic evidences for the effective administration of the criminal justice system. It is an excellent source of information for forensics scientists and legal professionals.

Covers new trace evidence techniques and expanding areas of analysis, along with key theory and applications Developed around the need for updated information in the disciplines of trace evidence the Handbook of Trace Evidence Analysis focuses on the increasing awareness and need for validation, modern methods for addressing and controlling contamination, the shift towards incorporating statistical analyses into the interpretation phase and cutting edge research into new forensic science methods and their application. Beginning with an overview of the topic and discussing the important role that information derived from trace materials can provide during investigations, the book then presents chapters on key techniques. The first being the critical nature of microscopy, and the methods employed for the recognition, collection, and preservation of trace evidence. Subsequent chapters review the core disciplines of trace evidence examination: paints and polymers, hairs, fibers and textiles and glass. Each chapter contains in-depth discussions on the origin of the materials involved, including any natural or synthetic processes involved in their production, the nuances involved in their detection, and the methods of analysis that are used to extract valuable information from samples. In addition, suggested workflows in method and testing selections, as well as addressing specific scientific challenges as well as the limitations of knowledge on the transfer, persistence and background abundance of trace materials are discussed. The book ends by examining the interpretation of trace evidence findings from a historical perspective and examining the methods that are currently being developed. Provides an in-depth introduction to the general area of trace evidence and discusses current and new techniques Consolidates trace evidence and materials categories of testing into one reference series Offers a detailed focus on technical approaches and guidelines to trace evidence Includes analytical schemes/workflows and valuable guides for the interpretation of data and results The Handbook of Trace Evidence will appeal to forensic science academics, students, and practitioners in the trace evidence and materials science disciplines, as well as DNA analysts, toxicologists, forensic anthropologists, crime laboratory managers, criminal justice students and practitioners, and legal professionals. It would also be a valuable resource for every crime laboratory reference library.
