Forensic Document Examination in the 21st Century covers the latest technology and techniques providing a complete resource on contemporary issues and methods in forensic document examination. Forensic document examiners provide their findings as expert testimony in court. Due to rapid changes in technology, including digital documents, printing and photocopying capabilities, and more, there is a great need for this up-to-date reference. The examination of documents can include comparison of handwriting or hand-printing; detection of alterations or photocopier and computer manipulation; restoration or decipherment of erased and obliterated writing; visualization of latent impressions; the identification of printing processes; and differentiation of inks. Computer-generated documents are prevalent, and electronically-captured signatures are becoming more widespread, meaning the knowledge of advances in technology and adoption of new validated techniques and methods of document examination are crucial to the reliability of forensic opinions. Forensic Document Examination in the 21st Century includes the latest research on the subject and with contributions from leading experts on their various areas of expertise. The book will be a welcome addition to the literature and support the foundational basis for methods and procedures for use it expert testimony in court, serving as a resource for forensic document examiners, trainees, and those in the criminal and legal communities who use the services of expert document examiners and witnesses
The Daubert trilogy of U.S. Supreme Court cases has established that scientific expert testimony must be based on science grounded in empirical research. As such, greater scrutiny is being placed on questioned document examination generally, and handwriting comparison in particular. Bridging the gap between theory and practice, The Neuroscience of Handwriting: Applications in Forensic Document Examination examines the essential neuroscientific principles underlying normal and pathological hand motor control and handwriting. Topics discussed include: Fundamental principles in the neuroanatomy and neurochemistry of hand motor control and their application to research in handwriting The epidemiology, pathophysiology, and motor characteristics of neurogenerative diseases such as Parkinson’s, Huntington’s, Alzheimer’s, multiple sclerosis, essential tremor, and motor neuron disease and their effects on handwriting Psychotropic medications prescribed for depression, bipolar disorder, and psychosis; their mechanisms of action; and their effect on motor behavior and handwriting The impact of substance abuse on handwriting An overview of the aging process and its effects on motor control and handwriting The kinematic approach and new findings on the kinematic analyses of genuine, disguised, and forged signatures The authors’ laboratory research on authentic and forged signatures An essential resource for professionals and researchers in the forensic documentation examination and legal communities, this volume provides a window on the scientific process of signature and handwriting authentication, integrating the extensive research on neural processes and exploring how disease, medication, and advanced age alter these processes.
Forensic Handwriting Identification: Fundamental Concepts and Principles teaches the law enforcement and legal communities the major principles involved in handwriting and hand-printing analysis as applied to many types of investigations, including fraud, homicide, suicide, drug trafficking/clandestine labs, sexual offenses, threats and extortion, blackmail, arson, bombings, and theft. Lawyers and investigators will learn how to interpret an examiner's report, the significance of various handwriting opinions and the influencing factors which must be considered. - Reviews basic concepts that affect a person's writing, demonstrates how to obtain handwriting specimens and evidence, and provides the appropriate ASTM and SWIGDOC standards and procedures - Ideally suited for forensic science and legal professionals, investigators working with document examiners, and law enforcement students and professionals - Includes model specimen handwriting forms
The examination of handwriting and signatures has a long and established history as a forensic discipline. With the advancement of technology in the use of digital tablets for signature capture, changes in handwriting examination are necessary. Other changes in handwriting, such as in increase in printed writing styles and the decrease in handwriting training in schools necessitates a re-examination of forensic handwriting identification problems. This text takes a fresh and modern look at handwriting examination as it pertains to forensic, legal, and criminal justice applications.
Disputed document inquiries encompass extensive and varied technical examinations, unique phases of investigation, and specialized legal presentations. This book serves as a guide to all aspects of a questioned document covering the broad spectrum of the work as it is practiced today. From the work of the field investigator and the examination of a document to the presentation of evidence in court, Scientific Examination of Questioned Documents provides a comprehensive approach that is ideal as a training manual for document examiners, investigators, and attorneys.
This book introduces the reader to the basic principles of handwriting and the factors that affect their development. The book discusses the basic concept of the characteristics of writing that are compared when making an identification or elimination of a writer. In addition, readers will be able to recognize the signs of forgery and disguise and to distinguish between simulation and disguise.
Forensic Document Examination enlightens forensic document examiners, forensic investigators, attorneys and others using the services of forensic document examiners with the basic principles and current trends in the area. Standards and methodologies apply now, which were non-existent 20 years ago. Instrumentation has moved beyond the microscope and the magnifying glass to digital cameras, digital microscopes, video spectral comparators, electrostatic detection devices for the development of indented writing on paper, scanners, and software programs like Write-On 2.0 and Photoshop. - Covers basic principles and methodologies used in forensic document examination - Contains state-of-the-art techniques and new trends - Includes research over the last ten years and describes the future direction of forensic document examination
Fraudulent identity and security documents are integral prerequisites for the smuggling of migrants, trafficking in persons, terrorist mobility, to facilitate the smuggling of drugs, weapons and other goods, and to commit fraud. Fraudulent documents are the grease that eases cross-border crime of all types. They include fraudulently obtained, illegally issued, forged and counterfeit documents. Many countries in the world recognize that forensic document examination is vital to immigration and border control security and have a forensic document examination facility. Although the ability to detect and disseminate intelligence about fraudulent documents is vital to border security, there are still countries lacking this capacity. Moreover, there is a lack of awareness among relevant criminal justice practitioners of the benefits that forensic document examinations may provide to assist border control security and immigration facilities. The Guide aims to provide practical assistance for the establishment or upgrading of forensic document examination capacities in two categories of service providers: (a) immigration and border control agencies and (b) forensic science laboratories. Several levels of infrastructure development ranging from basic to advanced capacity are covered. The focus is on the staff skill and educational requirements needed to perform forensic document examinations and to provide court testimony, intelligence alerts and training.
