In the wake of the Daubert ruling, the use of forensic toolmark evidence in court has been problematic, in that the conclusions of forensic scientists as to toolmark origin often lack scientifically sound statistical proof. In the Color Atlas of Forensic Toolmark Identification, noted forensic expert Nicholas Petraco helps move toolmark examination from an art to a science. The first part of the book contains an anthology of tried and true methods, procedures, and traditional techniques used by practitioners of this discipline for over a century. It contains rationales and methodologies for casework, discussion of the use of new materials and techniques for preparation of known standards, and the application of various methods of statistical proof to further establish toolmark examination as a sound scientific endeavor. The second section contains a compilation of commonly used hand tools and the marks they typically produce. Provides clear instruction on how to: Use lenses and microscopes to view images of toolmarks Make accurate and precise measurements of tools on macroscopic and microscopic scales Properly photograph toolmark evidence Compare a subject tool with the questioned toolmarks to determine toolmark origin Examines marks made by a range of tools, including: Screwdrivers Crowbars and prybars Handsaws Hammers Hatchets and Axes Wrenches Vise grips Pliers Wire cutters Metal snips Crimping tools Knives and scissors Chisels and punches Drill bits More than 400 color photos enhance the text, and numerous case studies describe evidence found and conclusions drawn from the evidence. This unique atlas empowers law enforcement professionals to capture the evidence they need to solve the case. About the Author Nicholas Petraco earned a B.S. in chemistry and an M.S. in forensic science from John Jay College of Criminal Justice, the City University of New York. He served as a detective/criminalist at New York City’s Police Laboratory from 1968 to 1990 and held the position of senior forensic microscopist of the laboratory’s trace section between 1982 and 1990, when he became a private forensic consultant. Mr. Petraco has helped educate thousands of forensic scientists, worked on more than 5000 death investigations on behalf of prosecution and defense attorneys, and testified as an expert in more than 500 trials conducted in local, state, and federal criminal and civil courts.

Criminal Dismemberment is the first book to examine dismemberment as a phenomenon in the context of criminal acts. While the number of such dismemberment cases in any given country is often small, the notion of dismemberment captures the imagination, often leading many to question the motivations as to why anyone would perpetrate such an unnatural act. The act of dismemberment, in its original form, referred to cutting, tearing, pulling, wrenching or otherwise separating the limbs from a living being as a form a capital punishment. In today’s society, it has become associated most frequently with the criminal act of sectioning the remains of the dead in an attempt to conceal the death and dispose of the remains or make the process of identification of the deceased more difficult to achieve. Drawing on expertise from leading forensic anthropologists, pathologists, and forensic materials engineers, the book brings together much of the literature on criminal dismemberment—viewing it from the investigative, forensic, and social science perspectives. Key features include: Psychological analysis of the perpetrator Detailed examination of case studies, anonymized from recent investigations Difficulties encountered in a dismemberment investigation Tool mark analysis, including knives and saws, accompanied by over 120 detailed, full-color illustrations and photographs Serves as a unique and useful resource in the investigation of dismembered human remains The diverse backgrounds of the contributors offers a thorough account of such topics as the history of dismemberment, the forensic pathology in such cases, the importance of developing a common vocabulary in terminology used, the legal admissibility in dismemberment cases. As such, Criminal Dismemberment will serve as a comprehensive reference for students and practitioners alike.

The textbook is an educational standard on the theory and practice of crime scene investigation and includes many informative casework examples and photographs. On reading this book, students, entry-level personnel, and experienced practitioners will have a better understanding of the strengths and limitations of forensic science in its application to crime scene investigations." —Professor Don Johnson, School of Criminal Justice and Criminalistics, California State University, Los Angeles The application of science and technology plays a critical role in the investigation and adjudication of crimes in our criminal justice system. But before science can be brought to bear on evidence, it must be recognized and collected in an appropriate manner at crime scenes. Written by authors with over 50 years of combined experience in forensic science, Techniques of Crime Scene Investigation examines the concepts, field-tested techniques, and procedures of crime scene investigation. Detectives, crime scene technicians, and forensic scientists can rely on this updated version of the "forensics bible" to effectively apply science and technology to the tasks of solving crimes. What’s New in the Eighth Edition: The latest in forensic DNA testing and collection, including low copy number DNA A new chapter on digital evidence New case studies with color photographs End-of-chapter study questions Practical tips and tricks of the trade in crime scene processing

Forensic taphonomy is the study of the postmortem changes to human remains, focusing largely on environmental effects—including decomposition in soil and water and interaction with plants, insects, and other animals. While other books have focused on subsets such as forensic botany and entomology, Manual of Forensic Taphonomy is the first update of the entire domain in more than ten years and the first book to consider distinguishing among multiple types of taphonomic changes. Edited by two of the most distinguished experts in the field, this volume examines taphonomic alterations to bone and related taphonomic processes common to cases of forensic interest. Specific chapters address a range of issues related to: Varying burial environments Animal scavenging and transport Fluvial and human transport Cultural modifications Marine environments Subaerial weathering Thermal alteration Recovery methods used in collecting the remains The book discusses inherent variations in survivability of different bones, degradation of DNA in different environments, and organisms involved in soft-tissue decomposition which result in skeletonization. It also describes microscopic alterations, color changes, macroscopic physical damage of multiple types, and bone loss through dispersal away from the location of initial body deposition. The authors present methods that can be employed to determine the timing of taphonomic damage (perimortem vs. postmortem) as well as checklists for the collection of microscopic and macroscopic taphonomic data. The ability to recognize taphonomic characteristics and discriminate between osseous alterations with similar appearances but dissimilar origins is essential to those engaged in the analysis of skeletal remains. This volume is an ideal guide for students and non-specialists as well as a reference manual for professionals.
