Forensic Handwriting Identification

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.

"Forensic document examination is the study of physical evidence and physical evidence cannot lie. Only its interpretation can err. Only the failure to find it, or to hear its true testimony can deprive it of its value."—Roy Huber This is a comprehensive update of Huber and Headrick's seminal work on handwriting examination. New coverage includes a review of forensic handwriting examination research, handwriting analysis training and proficiency, revised methods and procedures, an updated listing and clarification of terminology and electronic signatures, the analysis of digitized handwriting, and other related technological advances. The book includes updated photographs, several added illustrations, and advances in techniques based on the scientific research conducted in the area over the last 20 years. Features of the new edition include: The latest on electronic signatures, digital handwriting, automated handwriting verification, and the many advances in technology and research over the last two decades An overview of the fundamentals of handwriting examination with updated discussion of the intrinsic and extrinsic variables associated with handwriting identification A review of the criticism of handwriting expert opinions and methodology, addressing both the strengths and scientific limitations of the area Fully revised while remaining true to the spirit and approach of original authors Roy Huber and A. M. Headrick Addition of nearly 200 new references and new glossary terms representing advances in research and methods. With extensive photographs to help clearly illustrate concepts, Huber and Headrick’s Handwriting Identification: Facts and Fundamentals, Second Edition serves as an invaluable reference to law libraries, practicing document examiners, forensic and criminal justice students, and every lawyer handling cases in which the authenticity of handwriting and documents might be disputed.

"Forensic document examination is the study of physical evidence and physical evidence cannot lie. Only its interpretation can err. Only the failure to find it, or to hear its true testimony can deprive it of its value." - Roy Huber, author A definitive review of handwriting identification, this book presents, in a general manner, how to approach document examination and then, in particular, how to apply handwriting identification to the document. Types of handwriting are discussed in detail. For the first time in the field of questioned document examination, Handwriting Identification: Facts and Fundamentals consolidates the pertinent information from published and unpublished sources respecting writing, that is essential to the expansion of a practitioner's general knowledge of handwriting identification and to the proper education of novices. Written in a question and answer format, the book suggests some of the questions that one might ask of an examiner and provides the answers that knowledgeable and competent examiners should be expected to give. This book is a valuable addition to law libraries and to every practicing document examiner, as well as every lawyer handling cases in which the authenticity of handwriting might be disputed.

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.

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.
