The Questioned Document Section of the Iowa DCI Criminalistics Laboratory provides a comprehensive range of document examinations and hand writing identification services to authorized agencies in the State of Iowa. This area of forensic science is a broad
field where both handwritten and machine produced documents are characterized and compared to determine facts about their origins. A document is a substrate with marks or symbols which convey thoughts. A document in a criminal matter is the only physical evidence that portrays thoughts. The forensic document examiner makes scientific examinations, comparisons, and analyses of documents in order to: 1) establish genuineness or non-genuineness, 2) reveal alterations, additions,
or deletions, 3) identify or eliminate persons as the source of handwriting, 4) identify or eliminate the source of machine produced documents, 5) visualize other impressions, marks, or relevant evidence of any kind, and 6) write reports and give testimony. Other problems may involve the decipherment, restoration, or enhancement of obscured, deleted, or damaged parts of documents.
