Traditionally, forensic investigation has not been fully utilized in the investigation of property crime. This ground-breaking book examines the experiences of patrol officers, command staff, detectives, and chiefs as they navigate the expectations of forensic evidence in criminal cases, specifically property crimes cases. DNA and Property Crime Scene Investigation looks at the current state of forensic technology and, using interviews with police officers, command staff, forensic technicians, and prosecutors, elucidates who is doing the work of forensic investigation. It explores how better training can decrease backlogs in forensic evidence processing and prevent mishandling of crucial evidence. Concluding with a police chief’s perspective on the approach, DNA and Property Crime Scene Investigation provides insight into an emerging and important approach to property crime scene investigation. Key Features Provides practical information on implementing forensic investigation for property crimes Examines the current state of forensic technology and points to future trends Includes a police chief’s perspective on the forensic approach to investigating property crimes Utilizes interviews with professionals in the field to demonstrate the benefits of the approach
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).
The manner in which criminal investigators are trained is neither uniform nor consistent, ranging from sophisticated training protocols in some departments to on-the-job experience alongside senior investigators in others. Ideal for students taking a first course in the subject as well as professionals in need of a refresher, Introduction to Criminal Investigation uses an accessible format to convey concepts in practical, concrete terms. Topics discussed include: The history of criminal investigation in Western society Qualifications for becoming an investigator, the selection process, and ideal training requirements Crime scene search techniques, including planning and post-search debriefing Preparing effective field notes and investigative reports Interviewing and interrogating Types of evidence found at the crime scene and how to collect, package, and preserve it The contributions of forensic science to criminal investigations and the equipment used in crime labs Investigative protocol for a range of crimes, including property crimes, auto theft, arson, financial crimes, homicide, assault, sex crimes, and robbery Specialized investigations, including drug trafficking, cybercrime, and gang-related crime Legal issues involved in criminal investigations and preparing a case for trial Bringing together contributions from law enforcement personnel, academics, and attorneys, the book combines practical and theoretical elements to provide a comprehensive examination of today‘s criminal investigative process. The accessible manner in which the information is conveyed makes this an ideal text for a wide-ranging audience.
Evidence Found: An Approach to Crime Scene Investigation is not another analysis of forensic errors using an "After the Fact" or "Lessons Learned" approach but a "Before the Fact" guide that examines the thought processes that can lead to those mistakes. Plus a few extras tips and tricks from the author’s experience of over 25 years. Many high-profile crime scene investigations (and routine ones, for that matter) have suffered errors that have had negative impact on the investigation result and in the courtroom. Typically, we examine what happened and develop a useful list of what to do and what not to do, fixing the symptoms but potentially leaving ourselves open to the same error type on the next scene. The reason? Many crime scene mistakes are the result of systemic issues that are repeated due to a failure to include an evaluation of the decision-making process, including our own foundations of knowledge. Through case study and logical argument, this book attempts to provide a framework to recognize, evaluate, and alter negative decision-making patterns, including evaluating our own experience, before they negatively impact an investigation or the overall operation of a forensic unit. Enhances the base concepts of evidence search and sequential processing for error avoidance Examines the systemic areas/practices of a crime scene investigation where errors can occur Includes a Evidence Matrix - a crime scene evaluation tool that aids in sequential processing decisions Contains tips on overcoming common crime scene issues, inlcuding night time searches Provides courtroom Testimony - communicating comparison findings to a jury
The book outlines the general principles of forensic science including an overview of the history of forensic science, an introduction to ballistics, crime scene investigation techniques as well as evidence gathering, processing and documentation procedures. It presents valuable information on advanced forensic topics as well. These areas include criminal profiling, fingerprints and DNA as identification, the forensic autopsy, pharmacology, toxicology, and biohazard risks for the forensic investigator. The handbook also provides the reader with information on the American criminal justice system and how it relates to forensic science. It also features one of the most detailed and extensive forensic glossaries ever assembled. Included are more than 600 pertinent forensic terms with definitions that will serve as an invaluable desk reference for forensic novices and seasoned veterans alike.
Crime Scene Investigation offers an innovative approach to learning about crime scene investigation, taking the reader from the first response on the crime scene to documenting crime scene evidence and preparing evidence for courtroom presentation. It includes topics not normally covered in other texts, such as forensic anthropology and pathology, arson and explosives, and the electronic crime scene. Numerous photographs and illustrations complement text material, and a chapter-by-chapter fictional narrative also provides the reader with a qualitative dimension of the crime scene experience.
Veterinary Forensics: Investigation, Evidence Collection, and Expert Testimony will provide anyone involved in an investigation of an animal involved crime or civil action with the knowledge and tools that can give guidance for their actions in completing a forensic investigation. All 50 U.S. states, and numerous countries around the world, have laws against animal abuse and cruelty. Law enforcement agents, veterinarians, the judiciary, attorneys and forensic scientists may be involved in cases of animal cruelty, neglect or human crimes that may have an animal element. Additionally, the animal can be the victim, suspect or in some instances the witness of a crime. Given that acquittal or conviction is dependent upon the nature and veracity of the evidence, the quality of the evidence in an animal-related crime investigation must be beyond reproach. The book begins with a discussion of animal abuse and crimes against animals, crime scene investigation, and, from there, discusses various types of forensic examinations of the animal, culminating in a review of the judicial system and testimony in a court of law. All contributing authors are practicing professionals in law, veterinary medicine, and the private sector who provide current, best-practice evidence collection and forensic techniques. Chapters provide in-depth detail about the forensic clinical examination and forensic necropsy of small and large animal species, forensic radiology, forensic toxicology, bitemark analysis and animal behavior. Various, relevant forensic disciplines such as bloodstain pattern analysis, DNA analysis, animal sexual abuse, agroterrorism, animal hoarding, ritual crimes against animals, and animal fighting are discussed. Key Features: Presents established and accepted police techniques in animal crime scene investigation including identification, documentation and packaging of physical evidence and scene photography and videography Includes essential techniques to collect and preserve biological and DNA evidence for animal DNA testing Review of the forensic clinical examination and forensic necropsy of small and large animals Provides methods of evidence presentation in the courtroom, the nature of court room testimony, and the development of an expert report Veterinary Forensics: Investigation, Evidence Collection, and Expert Testimony fills the void of applied, real-world investigative techniques for the collection and presentation of veterinary forensic medical and scientific information. It will be a welcome reference to both the student and professional in the understanding all relevant evidentiary, investigative, and legal elements of the discipline.
Bridging the gap between practical crime scene investigation and scientific theory, Crime Scene Forensics: A Scientific Method Approach maintains that crime scene investigations are intensely intellectual exercises that marry scientific and investigative processes. Success in this field requires experience, creative thinking, logic, and the correct application of the science and the scientific method. Emphasizing the necessary thought processes for applying science to the investigation, this text covers: The general scene investigation process, including definitions and philosophy as well as hands-on considerations Archiving the crime scene through photography, sketching, and video Managing the crime scene investigation—the glue that holds the investigation together Searching the crime scene—the logical byproduct of archiving and management Impression/pattern evidence, including fingerprints, bloodstains, footwear impressions, and tire track impressions The biological crime scene and recognizing, collecting, and preserving biological evidence, including forensic entomology and evidence found at bioweapon scenes The fundamental principles of evidence as expressed by the Principle of Divisible Matter and the Locard Exchange Principle: every touch leaves a trace Trace evidence, including glass, paint, and soil Shooting incident scenes, with discussion of bullet paths and gunshot residue The final section examines fire scenes, quality assurance issues, and methods for collecting and preserving various evidence types not covered in other chapters. The delicate balance among logic, science, and investigative activity must be understood in order to successfully work a crime scene. Enhanced by more than 200 color images, this volume provides investigators and students with the tools to grasp these critical concepts, paving an expeditious path to the truth.
