Forensic Evidence: Investigation to Courtroom introduces criminal justice students to forensic science. This textbook assumes no previous exposure to the disciplines and focuses on what criminal justice students need to know about forensic science. Students are guided through the preservation and analysis of physical evidence in the crime lab to ensure the integrity of the evidence--whether exculpatory or associative--will be preserved and accepted in the courtroom. Forensic Evidence begins with a survey of the disciplines and their relationship to criminal justice and then goes on to examine the various types of forensic analyses, giving students an understanding of how scientists perform those laboratory examinations. It is designed to address the learning needs of criminal justice practitioners seeking to gain a more scientific understanding of forensic analysis while offering insights to scientists interested in the investigative aspects of the physical evidence they examine.
