This Third edition of the classic by America's leading forensic scientists gives you an insider's understanding of physical evidence at the crime scene.

Written in an easy-to-understand format, this outstanding guide, by the nation’s foremost forensic scientists, introduces you to the basics of crime scene evaluation. They teach you excellent ways to make your investigation solid and successful. This extensive resource is packed with valuable information about the details of collecting, storing, and analyzing all types of physical evidence. You’ll learn how to connect the victim(s) and suspect(s) to the crime scene, and to the physical evidence left behind. They also instruct you on how to use this information to provide convincing testimony based on scientific facts.

The book is divided into three parts plus appendices for easy access to the information you need. Part I offers an overview of forensic science and discusses the future path of forensic science and its applications in the courtroom and society. Part II gives you an exhaustive list of physical evidence typically left behind at crime scenes and explains the correct methods for processing this evidence. Part III discusses current issues in search and seizure, and how to effectively utilize it in court. The appendices discuss common blood screening test reagents and how to use the druggist’s fold for sealing evidence in paper.

This in-depth reference provides you with a wealth of details regarding many different topics including light, smoke, bullet identification, transient and pattern evidence, postmortem lividity marks and other special imprints and indentations, odors, wet versus dry blood samples, crime scene reconstruction techniques, and recognition and coordination of all elements of the crime scene during and after investigation.

This new edition of a classic is a must have for all crime scene investigators, law enforcement agencies, trial lawyers, and others involved in the investigative process.

"...this would be a welcome resource for beginning students ... it helps to organize the field and make it coherent."

Enrico Pelazzo
The Forensic Teacher Magazine

This text will be of immediate value to anyone who wants to know more about forensics than theyre likely to get from an introductory book, or even an basic course in the subject. The text is divided into three areas: general concepts in forensic science, laboratory analysis of physical evidence, and the legal aspects of forensic science. Each section is dealt with thoroughly and in an extremely orderly manner. The first section, general concepts in forensic science, is an introduction to the discipline with many clear examples and definitions. It also lays the groundwork for the proper frame of mind one needs to engage in the collection of forensic evidence, and the later analysis and use of that evidence. The second section, laboratory analysis of physical evidence, is a detailed description of exactly how to collect and analyze various types of physical evidence. The list of topics is exhaustive: arson and fire evidence, bite marks, blood, body fluids other than blood, bombs and explosives, chemical substances, computers as evidence, DNA analysis, documents, drugs and controlled substances, fibers, fingerprints, firearms, glass, gunshot residue, hair, imprint and impression evidence, pains, pattern evidence, plastics, semen, serial number restoration, soil, tape, toolmarks, video evidence, and voice identification. Keep in mind that each chapter discusses what the evidence is, how to collect it, and how to analyze it. There is no discussion of the history of the science in each case, or of famous cases where this type of evidence proved crucial. This is the information you want and no more if youre interested in identifying, collecting, and analyzing each type of evidence. And, while it may not make for compelling summer-on-the-beach reading, it will prove invaluable when it comes to making sure your content is correct for your students, that theyre collecting and processing it in a recommended fashion, and that they know what to do with it.; The third section deals extensively with the law, specifically search and seizure, but manages to remain interesting to read. The appendix gives recipes for many of the reagents used in the book, and a comprehensive index follows. The title of this book says it all: this one is just about everything you want to know about finding, collecting, and processing each kind of physical evidence. Photographs are liberally sprinkled throughout. If you want a storybook or a sensational account of killers and criminals look elsewhere. Everyone else, especially teachers, will appreciate the material between its covers.
