Book Description
The identification and quantification of material present and collected at a crime scene are critical requirements in investigative analyses. Forensic analysts use a variety of tools and techniques to achieve this, many of which use light. Light is not always the forensic analyst’s friend however, as light can degrade samples and alter results. This book details the analysis of a range of molecular systems by light-based techniques relevant to forensic science, as well as the negative effects of light in the degradation of forensic evidence, such as the breakage of DNA linkages during DNA profiling. The introductory chapters explain how chemiluminescence and fluorescence can be used to visualise samples and the advantages and limitations of available technologies. They also discuss the limitations of our knowledge about how light could alter the physical nature of materials, for example by breaking DNA linkages during DNA profiling or by modifying molecular structures of polymers and illicit drugs. The book then explains how to detect, analyse and interpret evidence from materials such as illicit drugs, agents of bioterrorism, and textiles, using light-based techniques from microscopy to surface enhanced Raman spectroscopy. Edited by active photobiological and forensic scientists, this book will be of interest to students and researchers in the fields of photochemistry, photobiology, toxicology and forensic science.

Book Description
Alternate Light Source Imaging provides a brief guide to digital imaging using reflected infrared and ultraviolet radiation for crime scene photographers. Clear and concise instruction illustrates how to accomplish good photographs in a variety of forensic situations. It demonstrates how tunable wavelength light sources and digital imaging techniques can be used to successfully locate and document physical evidence at the crime scene, in the morgue, or in the laboratory. The scientific principles that make this type of photography possible are described, followed by the basic steps that can be utilized to capture high quality evidentiary photographs.

Book Description
Representations of forensic procedures saturate popular culture in both fiction and true crime. One of the most striking forensic tools used in these narratives is the chemical luminol, so named because it glows an eerie greenish-blue when it comes into contact with the tiniest drops of human blood.Luminol is a deeply ambivalent object: it is both a tool of the police, historically abused and misappropriated, and yet it offers hope to families of victims by allowing hidden crimes to surface. Forensic enquiry can exonerate those falsely accused of crimes, and yet the rise of forensic science is synonymous with the development of the deeply racist 'science' of eugenics.Luminol Theory investigates the possibility of using a tool of the state in subversive, or radical, ways. By introducing luminol as an agent of forensic inquiry, Luminol Theory approaches the exploratory stages that a crime scene investigation might take, exploring experimental literature as though these texts were 'crime scenes' in order to discover what this deeply strange object can tell us about crime, death, and history, to make visible violent crimes, and to offer a tangible encounter with death and finitude. At the luminol-drenched crime scene, flashes of illumination throw up words, sentences, and fragments that offer luminous, strange glimpses, bobbing up from below their polished surfaces. When luminol shines its light, it reveals, it is magical, it is prescient, and it has a nasty allure.TABLE OF CONTENTS // Preface: Christmas, Colorado, 1996 - Section I.

Book Description
This is a guide to recommended practices for crime scene investigation. The guide is presented in five major sections, with sub-sections as noted: (1) Arriving at the Scene: Initial Response/Prioritization of Efforts (receipt of information, safety procedures, emergency care, secure and control persons at the scene, boundaries, turn over control of the scene and brief investigator/s in charge, document actions and observations); (2) Preliminary Documentation and Evaluation of the Scene (scene assessment, "walk-through" and initial documentation); (3) Processing the Scene (team composition, contamination control, documentation and prioritize, collect, preserve, inventory, package, transport, and submit evidence); (4) Completing and Recording the Crime Scene Investigation (establish debriefing team, perform final survey, document the scene); and (5) Crime Scene Equipment (initial responding officers, investigator/evidence technician, evidence collection kits).

Book Description
Television shows like CSI, Forensic Files, and The New Detectives make it look so easy. A crime-scene photographer snaps photographs, a fingerprint technician examines a gun, uniformed officers seal off a house while detectives gather hair and blood samples, placing them carefully into separate evidence containers. In a crime laboratory, a suspect's hands are meticulously examined for gunshot residue. An autopsy is performed in order to determine range and angle of the gunshot and time-of-death evidence. Dozens of tests and analyses are performed and cross-referenced. A conviction is made. Another crime is solved. The credits roll. The American public has become captivated by success stories like this one with their satisfyingly definitive conclusions, all made possible because of the wonders of forensic science. Unfortunately, however, popular television dramas do not represent the way most homicide cases in the United States are actually handled. Crime scenes are not always protected from contamination; physical evidence is often packaged improperly, lost, or left unaccounted for; forensic experts are not always consulted; and mistakes and omissions on the autopsy table frequently cut investigations short or send detectives down the wrong investigative path. In Forensics Under Fire, Jim Fisher makes a compelling case that these and other problems in the practice of forensic science allow offenders to escape justice and can also lead to the imprisonment of innocent people. Bringing together examples from a host of high-profile criminal cases and familiar figures, such as the JonBenet Ramsey case and Dr. Henry Lee who presented physical evidence in the O. J. Simpson trial, along with many lesser known but fascinating stories, Fisher presents daunting evidence that forensic science has a long way to go before it lives up to its potential and the public's expectations.
