Human Body Decomposition

The fate of the human body after death is a subject that has fascinated enquirers, both in the scientific and legal realms for millennia. However, objective research into the causes and nature of human decomposition has only taken place in the last two centuries, and quantitative measurement of the process as a means of estimating the time of death has only recently been attempted. The substantial literature concerning this research has been published in numerous scientific journals since the beginning of the nineteenth century. Human Body Decomposition expands on the current literature to include the evolving research on estimating the time of death. This volume details the process of decomposition to include early period after death when the body cools to ambient temperature, and when the body begins to putrefy. This process is significant because the estimation of the time of death becomes increasingly more difficult when the body begins to putrefy. Human Body Decomposition compiles a chronological account of research into the estimation of the time since death in human bodies found decomposed in order that researchers in the subject field can concentrate their thoughts and build on what has been achieved in the past. Provides concise details of research, over the last 200 years, of estimating the time of death in decomposed bodies. Covers methods of research into human decomposition in the stages of body cooling to ambient temperature and the later stages of autolysis, putrefaction and skeletonisation. Includes a detailed account of recent research and future concepts. Concludes with an account of the difficulties which future research into human decomposition will encounter.

Estimation of the Time Since Death remains the foremost authoritative book on scientifically calculating the estimated time of death postmortem. Building on the success of previous editions which covered the early postmortem period, this new edition also covers the later postmortem period including putrefactive changes, entomology, and postmortem r

Estimation of the Time Since Death is a current comprehensive work on the methods and research advances into the time since death and human decomposition. This work provides practitioners a starting point for research and practice to assist with the identification and analysis of human remains. It contains a collection of the latest scientific research, various estimation methods, and includes case studies, to highlight methodological application to real cases. This reference first provides an introduction, including the early postmortem period, biochemical methods, and the value of entomology in estimating the time since death, along with other factors affecting the decomposition process. Further coverage explores importance of microbial communities in estimating time since death. Separate chapters on aquatic environments, carbon 14 dating and amino acid racemization, and total body scoring will round out the reference. The final chapter ties together the various themes in the context of the longest running human decomposition facility in the world and outlines future research directions. Provides the first comprehensive reference to bring together all aspects of knowledge relating to the estimation of the post-mortem interval in decomposed human bodies Contains real case studies that underscore key estimation concepts Demonstrates the changing role of technology and advances in the estimation of time since death

A truly interdisciplinary approach to this core subject within Forensic Science Combines essential theory with practical crime scene work Includes case studies Applicable to all time periods so has relevance for conventional archaeology, prehistory and anthropology Combines points of view from both established practitioners and young researchers to ensure relevance

Publius Syrus stated back in 42 B.C., “You cannot put the same shoe on every foot.” (Maxim 596) Though written long before the advent of forensic science, Syrus’ maxim summarizes the theme of Forensic Medicine of the Lower Extremity: Human Identification and Trauma Analysis of the Thigh, Leg, and Foot. Put simply, the lower extremity is a tremendously variable anatomic region. This variation is beneficial to forensic experts. Differences in the leg and foot can be used to establish individual identity. Analysis of damage to the lower limb can be used to reconstruct antemortem, perimortem, and postmortem trauma. As a forensic anthropologist, I analyze cases involving decomposed, burned, m- mified, mutilated, and skeletal remains. Many of the corpses I examine are incomplete. Occasionally, I receive nothing but the legs and feet; a lower torso dragged from a river; a foot recovered in a city park; dismembered drug dealers in plastic bags; victims of bombings and airline disasters; and the dead commingled in common graves. Though the leg and foot contain much that is useful in forensic analysis, before this publication, investigators faced a twofold problem. Little research that focused on the lower extremity was available in the literature, and the existing research was published in diverse sources, making its location and synthesis a daunting task.

Soils have important roles to play in criminal and environmental forensic science. Since the initial concept of using soil in forensic investigations was mooted by Conan Doyle in his Sherlock Holmes stories prior to real-world applications, this branch of forensic science has become increasingly sophisticated and broad. New techniques in chemical, physical, biological, ecological and spatial analysis, coupled with informatics, are being applied to reducing areas of search by investigators, site identification, site comparison and measurement for the eventual use as evidence in court. Soils can provide intelligence, in assisting the determination of the provenance of samples from artifacts, victims or suspects, enabling their linkage to locations or other evidence. They also modulate change in surface or buried cadavers and hence affect the ability to estimate post-mortem or post-burial intervals, and locate clandestine graves. This interdisciplinary volume explores the conceptual and practical interplay of soil and geoforensics across the scientific, investigative and legal fields. Supported by reviews, case-studies from across the world, and reports of original research, it demonstrates the increasing convergence of a wide range of knowledge. It covers conceptual issues, evidence (from recovery to use in court), geoforensics, taphonomy, as well as leading-edge technologies. The application of the resultant soil forensics toolbox is leading to significant advances in improving crime detection, and environmental and national security.

Forensic Microbiology focuses on newly emerging areas of microbiology relevant to medicolegal and criminal investigations: postmortem changes, establishing cause of death, estimating postmortem interval, and trace evidence analysis. Recent developments in sequencing technology allow researchers, and potentially practitioners, to examine microbial communities at unprecedented resolution and in multidisciplinary contexts. This detailed study of microbes facilitates the development of new forensic tools that use the structure and function of microbial communities as physical evidence. Chapters cover: Experiment design Data analysis Sample preservation The influence of microbes on results from autopsy, toxicology, and histology Decomposition ecology Trace evidence This diverse, rapidly evolving field of study has the potential to provide high quality microbial evidence which can be replicated across laboratories, providing spatial and temporal evidence which could be crucial in a broad range of investigative contexts. This book is intended as a resource for students, microbiologists, investigators, pathologists, and other forensic science professionals.

Links have recently been established between the study of death assemblages by archaeologists and paleontologists (taphonomy) and the application of physical anthropology concepts to the medicolegal investigation of death (forensic anthropology). Forensic Taphonomy explains these links in a broad-based, multidisciplinary volume. It applies taphonomic models in modern forensic contexts and uses forensic cases to extend taphonomic theories. Review articles, case reports, and chapters on methodology round out this book's unique approach to forensic science.
