"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 in handwriting and signature cases can be complicated by writers with motor disorder conditions such as Parkinson's disease and essential tremor. These conditions are more prevalent among the elderly and legal issues arise in probate and elder abuse fraud cases where parkinsonian patients sign their signatures to checks, estate, title, and financial documents that are frequently contested. Because writers with motor disorders produce distorted, tremulous handwriting, distinguishing between genuine movement disorder signatures and forgeries can be problematic for handwriting experts. To address the problem, the author conducts original research using innovative digital tablet technology that allows for objective, quantifiable measurement of dynamic handwriting factors such as duration, velocity, pressure, and frequency spectrum analysis of writing tremor. The results have implications not only for handwriting experts working with ink writing and online biometric signatures, but also the elderly, motor disorder patients, legal professionals, investigators, law enforcement, and the justice system.
