The Evidence Collection handbook was developed with the special needs of both law enforcement officers and criminal justice students in mind.The beginning of any successful investigation hinges on the proper collection of evidence. In many areas of the country, responding officers may have to wait hours for laboratory resources to arrive at a crime scene--or they may never have the benefit of expert assistance at all. In addition, even major metropolitan departments have limited laboratory personnel that can be sent to crime scenes. Therefore, it is essential that field personnel be prepared to competently identify and collect evidence for submission to a crime laboratory. The handbook is designed to serve as a quick reference on effective procedures for the collection, preservation, and transmittal of evidence for examination, analysis, and presentation at the time of prosecution.Divided into five sections, Evidence Collection covers:1. Crime Scene Incident Evidence Collection: Discusses various types of crime incidents and the typical evidence found at the scene.2. Collection and Preservation of Evidence: Describes procedures for collecting and preserving 16 categories of evidence.3. Transmittal of Evidence to a Laboratory: Describes procedures for forwarding evidence to a forensic laboratory.4. Laboratory Analysis and Examination Time: Discusses techniques available at forensic laboratories for evaluating and analyzing evidence.5. Glossary: Explains technical terms often used in forensic science.
Crime scene investigators are the foundation for every criminal investigation. The admissibility and persuasiveness of evidence in court, and in turn, the success of a case, is largely dependent upon the evidence being properly collected, recorded, and handled for future analysis by investigators and forensic analysts in the lab.

Even a seemingly trivial mistake in how physical evidence is collected and handled can jeopardise an entire criminal case. The authors present this guide to crime scene procedures, a practical handbook designed for all involved in such work.
This is a guide to recommended practices for crime scene investigation. The guide is presented in five major sections, with sub-sections as noted: (1) Arriving at the Scene: Initial Response/Prioritization of Efforts (receipt of information, safety procedures, emergency care, secure and control persons at the scene, boundaries, turn over control of the scene and brief investigator/s in charge, document actions and observations); (2) Preliminary Documentation and Evaluation of the Scene (scene assessment, "walk-through" and initial documentation); (3) Processing the Scene (team composition, contamination control, documentation and prioritize, collect, preserve, inventory, package, transport, and submit evidence); (4) Completing and Recording the Crime Scene Investigation (establish debriefing team, perform final survey, document the scene); and (5) Crime Scene Equipment (initial responding officers, investigator/evidence technician, evidence collection kits).
Prepared as a quick reference for use at a crime scene, the Evidence Collection Field Guide reviews the procedures for collecting and preserving 25 alphabetized categories of evidence in a concise, easy to locate manner. This handy reference will provide field personnel a method of verifying techniques and processes to ensure consistency and accuracy in collecting evidence for later use during forensic examination, and in prosecution.

It examines in detail the properties of biological/DNA evidence, bullet casings and gunshot residue, explosive and fire debris, fibers and hair, fingerprint, footprint, and tire impression evidence, and much more. This guide is a vital companion for forensic science technicians, crime scene investigators, evidence response teams, and police officers.
