Chapters focus on classification of physical evidence and stages in physical evidence analysis; methods used in forensic science (chemical, biological, and microscopical); and specific types of physical evidence. Separate chapters describe arson accelerants and explosives, drug analysis and forensic toxicology, transfer and trace evidence, and glass and soil. Other sections discuss fibers and hairs, blood, body fluids, physical patterns, fingerprints and other patterns for personal identification, document examination, and toolmarks and firearms. Chapter study questions, references, tables, photographs, figures, and an index are included. Appendixes discuss scientific measurement and the metric system, general crime scene procedures, and fundamentals of photography.
