Scientific examination of questioned documents

This guide to all aspects of a questioned document for attorneys, investigators, document examiners, and others covers the scientific examination of questioned documents and also the steps to be taken by field investigators and trial attorneys, as well as the techniques of presenting evidence in court. The text begins with basic definitions of terms and then discusses what examination of a document may reveal, including instruments and materials used to prepare documents, alterations in documents, damaged documents, accidental markings and impressions, and additional clues. Discovery of facts by comparison with known material is discussed in terms of handwriting identification; the identification of signatures and the detection of forgery; identification of handlettering and numerals; typewriting identification; and other mechanical impressions, including check writers and printing identifications. The age of a document is also considered. The attorney-investigator's role in a questioned document problem requires preparation and collection of handwriting and typewriting standards; and the proper care, handling, and preservation of documents, as well as reproduction of documents. Considerations for bringing the document problem to court involve preparation for trial and anticipating events in the courtroom. Illustrations, footnotes, and an index are provided.
