About «Crime Scene Investigation Study Guide »
DNA does not solve criminal cases people do. Investigators must document every action, photograph every item of evidence, and create a complete case file that can be used to convict the guilty and exonerate the innocent. Each chapter begins with an overview of the felony investigated in the case study and highlights a key area of crime scene investigation. You will then use the case studies to walk through the investigative process and learn by example to create accurate case files."
