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 considerationsArchiving the crime scene through photography, sketching, and videoManaging the crime scene investigation—the glue that holds the investigation togetherSearching the crime scene—the logical byproduct of archiving and managementImpression/pattern evidence, including fingerprints, bloodstains, footwear impressions, and tire track impressionsThe biological crime scene and recognizing, collecting, and preserving biological evidence, including forensic entomology and evidence found at bioweapon scenesThe 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 soilShooting incident scenes, with discussion of bullet paths and gunshot residueThe 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.

In Who They Were, Dr. Robert C. Shaler, the man who directed the largest and most groundbreaking forensic DNA investigation in U.S. history, tells with poignant clarity and refreshing honesty the story behind the relentless effort to identify the 2,749 victims of the attacks on the World Trade Center. No part of the investigation into the 9/11 attacks has taken as long or been less discussed than the daunting task of identifying the victims -- and the hijackers -- from the remains in the rubble of Ground Zero. In Who They Were, Dr. Robert C. Shaler, former director of the Forensic Biology Department at the New York City Office of the Chief Medical Examiner, tells the inside story of the relentless process of DNA identification and depicts the victories and frustrations that he and his team of scientists experienced during more than three years of grueling work. On September 11, 2001, New York City was unprepared for the mass-fatality event that occurred at the World Trade Center. The Office of the Chief Medical Examiner had to completely reconfigure itself to process and identify the nearly 20,000 remains that would eventually come through its doors. Facing an astonishing array of obstacles -- from political infighting and an overwhelming bureaucracy to the nearly insurmountable task of corralling personnel and supplies to handle the work -- Shaler and his team quickly established an unprecedented network of cooperation among public agencies and private labs doing cutting-edge research. More than a story of innovative science at the frontiers of human knowledge, Who They Were also tells the very human story of how Dr. Shaler and his staff forged important and lasting bonds with the families of those who were lost. He shares the agony of mistakes made in the chaos and unintended misidentifications resulting in the excruciating difficulty of having to retrieve remains from families of the lost. Finally, Dr. Shaler shares how he and the dedicated team of scientists who gave up more than three years of their lives when the rest of the world had moved on had to face the limits of science in dealing with the appalling level of destruction at Ground Zero and concede that no more victims would be sent home to their families. As of April 2005, when the process was suspended, only 1,592 out of the 2,749 who died on that fateful day had been identified. With compelling prose and insight, Who They Were reveals the previously untold stories of the scientists determined to bring closure to devastated families in the wake of America's largest disaster.
