What causes competent and dedicated investigators to make avoidable mistakes, jeopardizing the successful resolution of their cases? Authored by a 21-year police veteran and university research professor, Criminal Investigative Failures comprehensively defines and discusses the causes and problems most common to failed investigations. More importantly, it outlines realistic strategies for avoiding investigative pitfalls.
Illuminated with case studies, this practical resource examines three main reasons for investigative failure:
The Dangers of Assumptions and Organizational Ego
Authoritative contributors from a variety of disciplines elaborate on the aforementioned core points with commentary and case studies of well-known crimes. Written in a quick-to-grasp style, this useful text provides practical advice for avoiding investigative failures. It is an invaluable reference for investigators looking to prevent future failures of justice and find the truth.
The Certified Criminal Investigator Body of Knowledgeprepares candidates for the Certified Criminal Investigator®, CCI® program, the first open source, peer-reviewed credential in the world. The program sets standards for criminal investigation in a time when certification for investigators is crucial to filling gaps in the field. This book covers all aspects of the criminal investigation process to enable candidates to meet the requirements of the program. It reviews the history and development of forensic studies, ethical behavior of the investigator, evidence collection and preservation, investigation management, and courtroom demeanor and testimony.
Fulfilling a need for standardization of knowledge and competency in criminal investigation education, The Certified Criminal Investigator Body of Knowledge provides a thorough resource for the candidate preparing to become a criminal investigator. It also serves as a handy reference for the professional working through an investigation.
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.
Using a pedagogical format, with each chapter building on the previous one, the book is divided into three sections. The first explains the history and theory of fingerprint analysis, fingerprint patterns and classification, and the concept of biometrics—the practice of using unique biological measurements or features to identify individuals. The second section discusses forensic light sources and physical and chemical processing methods. Section Three covers fingerprint analysis with chapters on documentation, crime scene processing, fingerprint and palm print comparisons, and courtroom testimony.
Designed for classroom use, each chapter contains key terms, learning objectives, a chapter summary, and review questions to test students’ assimilation of the material. Ample diagrams, case studies, and photos demonstrate concepts in a way that prepares students for working actual cases.
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 avoidanceExamines the systemic areas/practices of a crime scene investigation where errors can occurIncludes a Evidence Matrix - a crime scene evaluation tool that aids in sequential processing decisionsContains tips on overcoming common crime scene issues, inlcuding night time searchesProvides courtroom Testimony - communicating comparison findings to a jury
The role of the Criminalist is to analyze, compare, identify, and interpret physical evidence in the crime lab. These crime labs, or forensic labs, have two primary functions: identifying evidence and linking the suspect, victim, and crime scene through physical evidence.
This new primer introduces the learner to the structure and organization of the crime lab and to the role of the Criminalist. It features real cases – recent and historic – to illustrate concepts. Colorful pedagogy clearly defines chapter elements and sets this text apart from next best. Topics covered include how to process a crime scene and preserve evidence, the basic principles of firearm examination, latent fingerprints, and rudimentary toxicology, or how to determine the presence or absence of drugs and poisons.
Well organized and methodical, this textbook has the potential to become the standard text for applying techniques of the physical and natural sciences to examining physical evidence.Uses real cases – recent and historic – to illustrate conceptsColorful pedagogy clearly defines chapter elements and sets this text apart from next bestPresents the basics of forensic sciences in a one-semester or one-year courseOffers excellent preparation for professional examinationsDelivers the latest in laboratory technique while acknowledging the limits of technology
