Forensic Microscopy: A Laboratory Manual will provide the student with a practical overview and understanding of the various microscopes and microscopic techniques employed within the field of forensic science. Each laboratory experiment has been carefully designed to cover the variety of evidence disciplines within the forensic science field with carefully set out objectives, explanations of each topic and worksheets to help students compile and analyse their results. The emphasis is placed on the practical aspects of the analysis to enrich student understanding through hands on experience. The experiments move from basic through to specialised and have been developed to cover a variety of evidence disciplines within forensic science field. The emphasis is placed on techniques currently used by trace examiners. This unique, forensic focused, microscopy laboratory manual provides objectives for each topic covered with experiments designed to reinforce what has been learnt along with end of chapter questions, report requirements and numerous references for further reading. Impression evidence such as fingerprints, shoe tread patterns, tool marks and firearms will be analysed using simple stereomicroscopic techniques.

A laboratory companion to Forensic Science: An Introduction to Scientific and Investigative Techniques and other undergraduate texts, Forensic Science Laboratory Manual and Workbook, Third Edition provides a plethora of basic, hands-on experiments that can be completed with inexpensive and accessible instrumentation, making this an ideal workbook for non-science majors and an excellent choice for use at both the high school and college level. This revised edition of a bestselling lab manual provides numerous experiments in odontology, anthropology, archeology, chemistry, and trace evidence. The experiments cover tests involving body fluid, soil, glass, fiber, ink, and hair. The book also presents experiments in impression evidence, such as fingerprints, bite marks, footwear, and firearms, and it features digital and traditional photography and basic microscopy. All of the experiments incorporate practical elements to facilitate the learning process. Students must apply the scientific method of reasoning, deduction, and problem-solving in order to complete the experiments successfully and attain a solid understanding of fundamental forensic science. Each of the 39 chapters features a separate experiment and includes teaching goals, offers the requisite background knowledge needed to conduct the experiments, and lists the required equipment and supplies. The book is designed for a cooperative learning setting in which three to five students comprise a group. Using the hands-on learning techniques provided in this manual, students will master the practical application of their theoretical knowledge of forensics.

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.

A broad understanding of bone and tooth microstructure is necessary for constructing the biological profile of an individual or individuals within a population. Bone Histology: An Anthropological Perspective brings together authors with extensive experience and expertise in various aspects of hard tissue histology to provide a comprehensive discussion of the application of methods, current theories, and future directions in hard tissue research related to anthropological questions. Topics discussed include: The biology underlying skeletal growth and development leading to adult skeletal morphology Current research in understanding in bone modeling Histological features of dental hard tissues and their utility in biological anthropology Histological analysis as a means to differentiate human from nonhuman bone and for the purpose of age estimation The biomechanics of cortical bone Histotaphonomy and how postmortem microstructural change can be used for taphonomic inquiry The application of light microscopy in paleopathology to classify pathological conditions The histological study of bone tissue of archaeological origin Researchers’ access to collections of bone samples with known demographic information Technological aspects of hard tissue histology, including laboratory requirements and high-resolution imaging In most cases, the physical remains of humans available to bioarchaeologists, paleopathologists, and paleontologists are limited to skeletal material. Fortunately, these hard tissues are a storehouse of information about biological processes experienced during the life of an individual. This volume provides an overview of the current state of research and potential applications in anthropology and other fields that employ a histological approach to the study of hard tissues.
