In the courtroom, critical and life-changing decisions are made based on quantitative forensic science data. There is often a range in which a measured value is expected to fall and, in this, an inherent uncertainty associated with such measurement. Uncertainty in this context is not error. In fact, estimations of uncertainty can add to the utility and reliability of quantitative results, be it the length of a firearm barrel, the weight of a drug sample, or the concentration of ethanol in blood. Measurement Uncertainty in Forensic Science: A Practical Guide describes and defines the concepts related to such uncertainty in the forensic context. The book provides the necessary conceptual background and framework-a baseline-for developing and deploying reasonable and defensible uncertainty estimations across forensic disciplines. Information is presented conceptually, using easily understood examples, to provide a readable, handy reference for scientists in the laboratory, as well as investigators and legal professionals who require a basic understanding of the science underpinning measurement results.

Interpreting Complex Forensic DNA Evidence is a handy guide to recent advances-and emerging issues-in interpreting complex DNA evidence and profiles for use in criminal investigations. In certain cases, DNA cannot be connected to a specific biological material such as blood, semen or saliva. How or when the DNA was deposited may be an issue. The possibility of generating DNA profiles from touched objects, where there may not be a visible deposit, has expanded the scope and number of exhibits submitted for DNA analysis. With such advances, and increasing improvements in technological capabilities in testing samples, this means it is possible to detect ever smaller amounts of DNA. There are also many efforts underway to seek was to interpret DNA profiles that are sub-optimal-either relative to the amount required by the testing kit and, potentially, the quality of the obtained sample. Laboratories often use enhancements in order to obtain a readable DNA profile. The broad-reaching implications of improving DNA sensitivity have led to this next, emerging generation of more complex profiles. Examples partial profiles that do not faithfully reflect the proposed donor, or mixtures of partial DNA from multiple people. A complexity threshold has been proposed to limit interpretation of poor-quality data. Research is now addressing the interpretation of transfer of trace amounts of DNA. Complex issues are arising in trial that need to be reconciled as such complexity has added challenges to the interpretation of evidence and its introduction or dismissal in certain cases in the courts. Key Features: Addresses DNA transfer, from person-to-person as well as to objects Outlines each stage required to produce a DNA profile from an exhibit-including collection, handling, storage, and analysis Discusses ethics, subjectivity, and bias-including cognitive dissonance-as they relate specifically to complex DNA evidence Highlights current techniques and the latest advances in DNA analysis, including advances in familial DNA searches Interpreting Complex Forensic DNA Evidence provides tools to assist the criminal investigator, forensic expert, and legal professional when posed with a DNA result in a forensic report or testimony. The result-and any associated statistic-may not reveal any ambiguity, complexity, or the assumptions involved in deriving it. Questions from resolved criminal cases are posed, and the relevant forensic literature, provided for the reader to assess a DNA result and any associated statistic. Case studies throughout illustrate concepts and emphasize the need for conclusions in the forensic report that are supported by the data.

Molecules of Murder is about infamous murderers and famous victims; about people like Harold Shipman, Alexander Litvinenko, Adelaide Bartlett, and Georgi Markov. Few books on poisons analyse these crimes from the viewpoint of the poison itself, doing so throws a new light on how the murders or attempted murders were carried out and ultimately how the perpetrators were uncovered and brought to justice. Part I includes molecules which occur naturally and were originally used by doctors before becoming notorious as murder weapons. Part II deals with unnatural molecules, mainly man-made, and they too have been dangerously misused in famous crimes. The book ends with the most famous poisoning case in recent years, that of Alexander Litvinenko and his death from polonium chloride. The first half of each chapter starts by looking at the target molecule itself, its discovery, its history, its chemistry, its use in medicine, its toxicology, and its effects on the human body. The second half then investigates a famous murder case and reveals the modus operandi of the poisoner and how some were caught, some are still at large, and some literally got away with murder. Molecules of Murder will explain how forensic chemists have developed cunning ways to detect minute traces of dangerous substances, and explain why some of these poisons, which appear so life-threatening, are now being researched as possible life-savers. Award winning science writer John Emsley has assembled another group of true crime and chemistry stories to rival those of his highly acclaimed Elements of Murder.

It was September 18, 2001, just seven days after al-Qaeda hijackers destroyed the Twin Towers. In the early morning darkness, a lone figure dropped several letters into a mailbox. Seventeen days later a Florida journalist died of inhalational anthrax. The death from the rare disease made world news. These anthrax attacks marked the first time a sophisticated biological weapon was released in the United States. It killed five people, disfigured at least 18 more, and launched the largest investigation in the FBI's history. Recounting the Anthrax Attacks explores the origins of the innovative forensics used in this case, while also explaining their historical context. R. Scott Decker's team pursued its first suspect with dogged determination before realizing that the evidence did not add up. With renewed energy, they turned to non-traditional forensics-scientific initiatives never before applied to an investigation-as they continued to hunt for clues. These advances formed the new science of microbial forensics, a novel discipline that produced critical leads when traditional methods failed. The new technologies helped identify a second suspect-one who possessed the knowledge and skills to unleash a living weapon of mass destruction. Decker provides the first inside look at how the investigation was conducted, highlighting dramatic turning points as the case progressed until its final solution. Join FBI agents as they race against terror and the ultimate insider threat-a decorated government scientist releasing powders of deadly anthrax. Walk in the steps of these dedicated officers while they pursue numerous forensic leads before more letters can be sent until finally they confront a psychotic killer.

Research on cybercrime has been largely bifurcated, with social science and computer science researchers working with different research agendas. These fields have produced parallel scholarship to understand cybercrime offending and victimization, as well as techniques to harden systems from compromise and understand the tools used by cybercriminals. The literature developed from these two fields is diverse and informative, but until now there has been minimal interdisciplinary scholarship combining their insights in order to create a more informed and robust body of knowledge. This book offers an interdisciplinary approach to research on cybercrime and lays out frameworks for collaboration between the fields. Bringing together international experts, this book explores a range of issues from malicious software and hacking to victimization and fraud. This work also provides direction for policy changes to both cybersecurity and criminal justice practice based on the enhanced understanding of cybercrime that can be derived from integrated research from both the technical and social sciences. The authors demonstrate the breadth of contemporary scholarship as well as identifying key questions that could be addressed in the future or unique methods that could benefit the wider research community. This edited collection will be key reading for academics, researchers, and practitioners in both computer security and law enforcement. This book is also a comprehensive resource for postgraduate and advanced undergraduate students undertaking courses in social and technical studies.

Melding a pilot's practical view of life in the cockpit with the expertise of an engineering professor to give readers an insider look at plane crashes. One of the most amazing feats of modern life is the frequency with which airplanes safely take off and land: about 40,000 times a day in the United States alone. Commercial aviation is by far the safest mode of transportation and is becoming safer all the time. But on the exceedingly rare occasion that a plane does crash, comprehensive accident analysis, thorough investigation, and implementation of remedial actions significantly reduces the probability of an already remote event ever recurring. Plane Crash, an unprecedented collaboration between mechanical engineering professor George Bibel and airline Captain Robert Hedges, shares the riveting stories of both high-profile and lesser-known airplane accidents. Drawing on accident reports, eyewitness accounts, and simple diagrams to explain what went wrong in the plane and in the cockpit, Hedges provides invaluable insight into aviation human factors, while Bibel analyzes mechanical failures. No prior scientific knowledge is needed to understand the principles and procedures this book describes, only an interest in the view from what Captain Hedges describes as "the best seat in the house." Organized around the phases of flight-takeoff, climb, cruise, approach, and landing-this book is a captivating look at some of the most dramatic plane crashes of the modern age, including Asiana Airlines 214, Air France 447, and Malaysia Airlines 370. If you have ever wondered what goes through a pilot's mind as a flight takes a turn for the dangerous, what impact turbulence actually has on flight safety, or even just how the wonders of aeronautics work to keep passengers safe day in and out, Plane Crash will both fascinate and educate.

Chapters address the more basic functions to serve as a primer for those transitioning to working digitally. There is also instruction on light and shadow, and bones and muscles of the skull. All of the discussion is intended to make the reader see things as an artist to improve drawing skills and overall digital techniques. In short, Digital Forensic Art Techniques is a practical, easy-to-follow manual for working forensic artists that will give readers a solid base from which to start. It serves as an essential resource to greater skill and comfort with the hardware and software, thus furthering current best practices and technological advances in the field.

A thumb print left at the scene of a grisly murder. Fingerprints taken from a getaway car used in a bank robbery. A palm print recovered from the shattered glass door of a burglarized home. Indeed, where crimes are committed, careless perpetrators will invariably leave behind the critical pieces of evidence-most likely in the form of fingerprints-needed to catch and convict them. But the science of fingerprint identification isn't always as cut and dry as detective novels and movies make it out to be.
