Challenges in Detection Approaches for Forensic Science


Book Description

Forensic science combines analytical science with the requirements of law enforcement agencies and legislation. This can often pose challenges within the development of novel analytical methods, particularly with the drive to have more in-field and in-situ applications to facilitate the investigation of criminal cases. This book will explore the specific challenges encountered by forensic scientists and the developments that are being made to address these within the framework of the legislative requirements. It will provide a critical appraisal of the current challenges facing analytical approaches for the detection of forensic evidence and the state of the art technologies used to address these challenges. Providing an excellent combination of current research and how this pertains to forensic investigations, the book will also highlight key obstacles within this ever-changing environment. Aimed at graduates and forensic professionals, this is a unique oversight of the current work being undertaken within the development of analytical methods and also in the interpretation of complex crime scene samples.




Forensic DNA Applications


Book Description

Forensic DNA Applications: An Interdisciplinary Perspective was developed as an outgrowth of a conference held by the International Society of Applied Biological Sciences. The topic was human genome–based applications in forensic science, anthropology, and individualized medicine. Assembling the contributions of contributors from numerous regions around the world, this volume is designed as both a textbook for forensic molecular biology students and a reference for practitioners and those in the legal system. The book begins with the history and development of DNA typing and profiling for criminal and civil purposes. It discusses the statistical interpretation of results with case examples, mitochondrial DNA testing, Y single nucleotide polymorphisms (SNPs) and short tandem repeats (STRs), and X SNP and STR testing. It also explores low copy number DNA typing, mixtures, and quality assurance and control. The second section examines the collection and preservation of biological evidence under a variety of different circumstances and the identification of human remains—including in mass disaster settings. It discusses applications to bioterrorism investigations, animal DNA testing in criminal cases, pedigree questions and wildlife forensic problems, applications in forensic entomology, and forensic botany. The third section explores recent developments and new technologies, including the rigorous identification of tissue of origin, mtDNA profiling using immobilized probe strips, chips and next-generation sequencing, the use of SNPs to ascertain phenotypic characteristics, and the "molecular autopsy" that looks at aspects of toxicogenetics and pharmacogenetics. The book concludes with a discussion on law, ethics, and policy. It examines the use of DNA evidence in the criminal justice system in both the United States and Europe, ethical issues in forensic laboratory practices, familial searches, DNA databases, ancestry searches, physical phenotyping, and report writing. The contributors also examine DNA applications in immigration and human trafficking cases and international perspectives on DNA databases.




Technology in Forensic Science


Book Description

The book "Technology in Forensic Science" provides an integrated approach by reviewing the usage of modern forensic tools as well as the methods for interpretation of the results. Starting with best practices on sample taking, the book then reviews analytical methods such as high-resolution microscopy and chromatography, biometric approaches, and advanced sensor technology as well as emerging technologies such as nanotechnology and taggant technology. It concludes with an outlook to emerging methods such as AI-based approaches to forensic investigations.




New Perspectives in Forensic Human Skeletal Identification


Book Description

New Perspectives in Forensic Human Skeletal Identification provides a comprehensive and up-to-date perspective on human identification methods in forensic anthropology. Divided into four distinct sections, the chapters will reflect recent advances in human skeletal identification, including statistical and morphometric methods for assessing the biological profile (sex, age, ancestry, stature), biochemical methods of identification (DNA analysis, stable isotope analysis, bomb curve analysis), and use of comparative radiography. The final section of this book highlights advances in human identification techniques that are being applied to international populations and disaster victims. The contributing authors represent established experts in forensic anthropology and closely related fields. New Perspectives in Forensic Human Skeletal Identification will be an essential resource for researchers, practitioners, and advanced students interested in state-of-the-art methods for human identification. - A comprehensive and up-to-date volume on human identification methods in forensic anthropology - Focuses on recent advances such as statistical and morphometric methods for assessing the biological profile, biochemical methods of identification and use of comparative radiography - Includes an entire section on human identification techniques being applied to international populations and disaster victims




DNA Technology in Forensic Science


Book Description

Matching DNA samples from crime scenes and suspects is rapidly becoming a key source of evidence for use in our justice system. DNA Technology in Forensic Science offers recommendations for resolving crucial questions that are emerging as DNA typing becomes more widespread. The volume addresses key issues: Quality and reliability in DNA typing, including the introduction of new technologies, problems of standardization, and approaches to certification. DNA typing in the courtroom, including issues of population genetics, levels of understanding among judges and juries, and admissibility. Societal issues, such as privacy of DNA data, storage of samples and data, and the rights of defendants to quality testing technology. Combining this original volume with the new update-The Evaluation of Forensic DNA Evidence-provides the complete, up-to-date picture of this highly important and visible topic. This volume offers important guidance to anyone working with this emerging law enforcement tool: policymakers, specialists in criminal law, forensic scientists, geneticists, researchers, faculty, and students.




Inside the Cell


Book Description

Josiah Sutton was convicted of rape. He was five inches shorter and 65 pounds lighter than the suspect described by the victim, but at trial a lab analyst testified that his DNA was found at the crime scene. His case looked like many others -- arrest, swab, match, conviction. But there was just one problem -- Sutton was innocent. We think of DNA forensics as an infallible science that catches the bad guys and exonerates the innocent. But when the science goes rogue, it can lead to a gross miscarriage of justice. Erin Murphy exposes the dark side of forensic DNA testing: crime labs that receive little oversight and produce inconsistent results; prosecutors who push to test smaller and poorer-quality samples, inviting error and bias; law-enforcement officers who compile massive, unregulated, and racially skewed DNA databases; and industry lobbyists who push policies of "stop and spit." DNA testing is rightly seen as a transformative technological breakthrough, but we should be wary of placing such a powerful weapon in the hands of the same broken criminal justice system that has produced mass incarceration, privileged government interests over personal privacy, and all too often enforced the law in a biased or unjust manner. Inside the Cell exposes the truth about forensic DNA, and shows us what it will take to harness the power of genetic identification in service of accuracy and fairness.




Fundamentals of Forensic Science


Book Description

Fundamentals of Forensic Science, Third Edition, provides current case studies that reflect the ways professional forensic scientists work, not how forensic academicians teach.
