The way a crime is defined is through criminal investigation. Criminal investigation is a multi-faceted effort that involves the study of facts presented by a criminal act or pattern of criminal conduct. These facts are then used to identify, locate and prove the guilt or innocence of a person or persons. Criminal investigation is usually carried out by a law enforcement agency using all of the resources available to discover, locate or establish evidence proving and verifying the relevant facts for presentation to a Court or other judicial authority. But how are these facts discovered? What resources do law enforcement use to uncover them? What is the process for a successful criminal investigation? In fact, how can we even define what is "criminal" in the first place? Daniel A. Reilly answers all these important questions, while providing the step by step process to gather facts, information, data, and evidence. Finding the Truth with Criminal Investigation is intended to answer all of the questions of who, what, where, when, why and how a violent crime occurred and/or was committed. It is intended for students in the field of criminal justice who wish to become criminal investigators - exposing them to the tools and processes needed to conduct a proper criminal investigation, but also real-life of working to support others as a team. Reilly spent a great deal of his professional life working on homicide cases, and he offers students his expertise in criminal investigation by successfully incorporating real-world context throughout this book.
