Methodologies and legislative frameworks regarding the archaeological excavation, retrieval, analysis, curation and potential reburial of human skeletal remains differ throughout the world. As work forces have become increasingly mobile and international research collaborations are steadily increasing, the need for a more comprehensive understanding of different national research traditions, methodologies and legislative structures within the academic and commercial sector of physical anthropology has arisen. The Routledge Handbook of Archaeological Human Remains and Legislation provides comprehensive information on the excavation of archaeological human remains and the law through 62 individual country contributions from Europe, Asia, Africa, North America, South America and Australasia. More specifically, the volume discusses the following: What is the current situation (including a brief history) of physical anthropology in the country? What happens on discovering human remains (who is notified, etc.)? What is the current legislation regarding the excavation of archaeological human skeletal remains? Is a license needed to excavate human remains? Is there any specific legislation regarding excavation in churchyards? Any specific legislation regarding war graves? Are physical anthropologists involved in the excavation process? Where is the cut-off point between forensic and archaeological human remains (e.g. 100 years, 50 years, 25 years...)? Can human remains be transported abroad for research purposes? What methods of anthropological analysis are mostly used in the country? Are there any methods created in that country which are population-specific? Are there particular ethical issues that need to be considered when excavating human remains, such as religious groups or tribal groups? In addition, an overview of landmark anthropological studies and important collections are provided where appropriate. The entries are contained by an introductory chapter by the editors which establish the objectives and structure of the book, setting it within a wider archaeological framework, and a conclusion which explores the current European and world-wide trends and perspectives in the study of archaeological human remains. The Routledge Handbook of Archaeological Human Remains and Legislation makes a timely, much-needed contribution to the field of physical anthropology and is unique as it combines information on the excavation of human remains and the legislation that guides it, alongside information on the current state of physical anthropology across several continents. It is an indispensible tool for archaeologists involved in the excavation of human remains around the world.

There are numerous criminal laws, criminal procedures, and expert testimony books, but no single one combines these key issues for the forensic science programs in the U.S. This book is a readable textbook for one-semester law or criminal law courses for forensic science students. It will cover criminal law broadly, focusing rather on the topic areas most important and salient to forensic scientists and students within forensic science including: moot court scenarios, 4th amendment search and seizure law, scientific evidence, expert testimony. All FEPAC accredited forensic science programs are required to teach at least 10 contact hours on criminal law.

The taphonomic approach within paleontology, archaeology, and paleoanthropology continues to produce advances in understanding postmortem biochemical and morphological transformations. Conversely, advances in understanding the early and intermediate postmortem period generated in the forensic realm can and should be brought to the attention of scientists who study the historic and prehistoric past.

Building on the success of Forensic Taphonomy: The Postmortem Fate of Human Remains, Advances in Forensic Taphonomy: Method, Theory, and Archaeological Perspectives presents new and updated techniques. It expands the taphonomic focus on biogeographic context and microenvironments and integrates further the theoretical and methodological links with archaeology and paleontology.

Topics covered include:
o Microenvironmental variation and decomposition in different environments
o Taphonomic interpretation of water deaths
o Mass graves, mass fatalities and war crimes, archaeological and forensic approaches
o Updates in geochemical and entomological analysis
o Interpretation of burned human remains
o Discrimination of trauma from postmortem change
o Taphonomic applications at the scene and in the lab

This comprehensive text takes an interdisciplinary and international approach to understanding taphonomic modifications. Liberally illustrated with photographs, maps, and other images, Advances in Forensic Taphonomy: Method, Theory, and Archaeological Perspectives is a valuable source of information for postmortem death investigation.

Since President John F. Kennedy's 1963 murder in Dallas, medical examiner and lawyer Dr. Cyril Wecht was initially inclined to accept the official theory that one person alone was responsible for the crime. But as Wecht delved into the evidence with boundless curiosity and unprecedented access, he came to understand that America had, instead, suffered a coup d'etat at the hands of rogue elements within our own government. Nobody else has Wecht's up-close and personal experience in uncovering the facts behind this assassination-and now he is sharing it with the world. Co-authored by investigative journalist Dawna Kaufmann, this comprehensive book reveals Wecht's analyses of the case's forensic and medical evidence. With his keen eye and sharp tongue, Wecht wields his scalpel on JFK's dubious autopsy report, the inept Warren Commission Report, the mishandling of crucial materials, all of the key players, and the media malpractice that has allowed the truth to remain hidden for nearly six decades.

The investigator's practical guide for cybercrime evidence identification and collection Cyber attacks perpetrated against businesses, governments, organizations, and individuals have been occurring for decades. Many attacks are discovered only after the data has been exploited or sold on the criminal markets. Cyber attacks damage both the finances and reputations of businesses and cause damage to the ultimate victims of the crime. From the perspective of the criminal, the current state of inconsistent security policies and lax investigative procedures is a profitable and low-risk opportunity for cyber attacks. They can cause immense harm to individuals or businesses online and make large sums of money--safe in the knowledge that the victim will rarely report the matter to the police. For those tasked with probing such crimes in the field, information on investigative methodology is scarce. The Cybercrime Investigators Handbook is an innovative guide that approaches cybercrime investigation from the field-practitioner's perspective. While there are high-quality manuals for conducting digital examinations on a device or network that has been hacked, the Cybercrime Investigators Handbook is the first guide on how to commence an investigation from the location the offence occurred--the scene of the cybercrime--and collect the evidence necessary to locate and prosecute the offender. This valuable contribution to the field teaches readers to locate, lawfully seize, preserve, examine, interpret, and manage the technical evidence that is vital for effective cybercrime investigation. Fills the need for a field manual for front-line cybercrime investigators Provides practical guidance with clear, easy-to-understand language Approaches cybercrime form the perspective of the field practitioner Helps companies comply with new GDPR guidelines Offers expert advice from a law enforcement professional who specializes in cybercrime investigation and IT security Cybercrime Investigators Handbook is much-needed resource for law enforcement and cybercrime investigators, CFOs, IT auditors, fraud investigators, and other practitioners in related areas.

This revised Third Edition includes new discussions of rules and case law analysis, forensic cases, and evidentiary software programs. Key Features: Every chapter contains new legal authority that apples to traditional legal principles relevant to evidence law Offers full coverage of evidentiary codes and statutes Provides practical forms, checklists, and additional tools throughout for use by current and future practitioners Course ancillaries including PowerPointTM lecture slides and an Instructor's Manual with Test Bank are available with qualified course adoption.

Information Security Policies, Procedures, and Standards: A Practitioner's Reference gives you a blueprint on how to develop effective information security policies and procedures. It uses standards such as NIST 800-53, ISO 27001, and COBIT, and regulations such as HIPAA and PCI DSS as the foundation for the content. Highlighting key terminology, policy development concepts and methods, and suggested document structures, it includes examples, checklists, sample policies and procedures, guidelines, and a synopsis of the applicable standards. The author explains how and why procedures are developed and implemented rather than simply provide information and examples. This is an important distinction because no two organizations are exactly alike; therefore, no two sets of policies and procedures are going to be exactly alike. This approach provides the foundation and understanding you need to write effective policies, procedures, and standards clearly and concisely. Developing policies and procedures may seem to be an overwhelming task. However, by relying on the material presented in this book, adopting the policy development techniques, and examining the examples, the task will not seem so daunting. You can use the discussion material to help sell the concepts, which may be the most difficult aspect of the process. Once you have completed a policy or two, you will have the courage to take on even more tasks. Additionally, the skills you acquire will assist you in other areas of your professional and private life, such as expressing an idea clearly and concisely or creating a project plan.

Gait analysis is the systematic study of human walking, using the eye and brain of experienced observers, augmented by instrumentation for measuring body movements, body mechanics, and the activity of the muscles. Since Aristotle's work on gait analysis more than 2000 years ago, it has become an established clinical science used extensively in the healthcare and rehabilitation fields for diagnosis and treatment. Forensic Gait Analysis details the more recent, and rapidly developing, use of gait analysis in the forensic sciences. The book considers the use of observational gait analysis, based on video recordings, to assist in the process of identification or exclusion. With the increase in use of CCTV and surveillance systems over the last 20 to 30 years, there has been a steady and rapid increase in the use of gait as evidence. Currently, gait analysis is widely used in the UK in criminal investigations, with increasing awareness of its potential use in the US, Europe, and globally. The book details the history of the science, current practices, and of the emergent application to establish best-practice standards that conform to those of other forensic science disciplines. Engagement with the Forensic Science Regulator, and the Chartered Society of Forensic Sciences in the UK, and the International Association for Identification has helped to ensure and enhance the quality assurance of forensic gait analysis. However, there remains a fundamental lack of standardized training and methodology for use in evidentiary and investigative casework. This book fills that void, serving as one of the first to describe the current state of practice, capabilities and limitations, and to outline methods, standards of practice and expectations of the gait analyst as a forensic practitioner. Forensic Gait Analysis reflects current research and forensic practice and will serve as a state-of-the-art guide to the use of gait analysis in the forensic context-for both education and training purposes. It will be a welcome addition to the libraries of professionals in the areas of podiatry, gait analysis, forensic video analysis, law enforcement, and legal practice.
