Chapter 15 What do you think a forensic document examiner can do? Kendall/Hunt

3 I. The Document Examiner
Chapter 15 I. The Document Examiner Involves the examination of handwriting, ink, paper, etc. to ascertain source or authenticity Their work usually involves examining _________ and _____________ to determine the _________ or _______________ of a questioned document. QUESTIONED DOCUMENT: any object with handwriting or print whose source or authenticity is in doubt Writing/markings on letters, checks, driver’s licenses, contracts, wills, voter registrations, passports, petitions, lottery tickets, walls, windows, doors, etc. handwriting source typescript authenticity Kendall/Hunt

4 Chapter 15 The Document Examiner Must be able to recognize efforts to alter documents through ____________, ___________ or ________________ of words to alter or obscure the original meaning of a document. Tries to recover the original contents of the writing May reconstruct writing on charred or burned papers Uncover the meaning of indented writings found on a paper pad after the top sheet has been removed Click to see video overwriting erasures crossing out Kendall/Hunt

5 Chapter 15 The Document Examiner Applies knowledge of microscopy, photography, chromatography to recognize and compare the individual characteristics of questioned and known authentic writings. Thus, getting documents of known authorship or origin is critical to the outcome of the examination. The uniqueness of handwriting makes this type of physical evidence, like fingerprints, one the few definitive individual characteristics available to the investigator. Kendall/Hunt

6 Chapter 15 Questioned Documents Involves the examination of handwriting, ink, paper, etc. to ascertain source or authenticity Examples include letters, checks, licenses, contracts, wills, passports Investigations include: verification, authentication, characterizing papers, pigments, and inks Kendall/Hunt

7 Chapter 15 Related Fields Historical Dating — the verification of age and value of a document or object Fraud Investigation — focuses on the money trail and criminal intent Paper and Ink Specialists — date, type, source, and/or catalogue various types of paper, watermarks, ink, printing/copy/fax machines, computer cartridges Forgery Specialists — analyze altered, obliterated, changed, or doctored documents and photos Typewriting Analysts — determine origin, make, and models Computer Crime Investigators — investigate cybercrime Kendall/Hunt

15 II. Handwriting Comparisons
Chapter 15 II. Handwriting Comparisons The early stages of learning handwriting are characterized by a conscious effort to copy standard letter forms. However, as writing skills improve, nerve and motor responses associated with the act of writing become subconscious. Zaner-Blaser method Kendall/Hunt

16 Handwriting Characteristics
Chapter 15 Handwriting Characteristics Line Quality Word and Letter Spacing Letter Comparison Pen Lifts Connecting strokes Beginning and ending strokes Unusual Letter Formation Shading or pen pressure Slant Baseline Habits Flourishes or embellishments Diacritic Placement ( dot i’s, cross t’s,etc.) Kendall/Hunt

17 Handwriting Handwriting analysis involves two phases:
Chapter 15 Handwriting Handwriting analysis involves two phases: The hardware — ink, paper, pens, pencils, typewriter, printers Visual examination of the writing Kendall/Hunt

18 Handwriting Comparisons
Chapter 15 Handwriting Comparisons Document experts continually testify to the fact that no two individuals write exactly alike. Many factors comprise the total character of a person’s writing. Individual variations associated with mechanical, physical, and mental functions make it extremely unlikely that any two people write identically. Thus, the unconscious handwriting of two different individuals can never be identical. Kendall/Hunt

19 Variations in Handwriting Characteristics
Chapter 15 Variations in Handwriting Characteristics NATURAL VARIATIONS: Normal deviations found between repeated specimens of an individual’s handwriting. Variations are expected in: Angularity Slope Speed Pressure letter and word spacing relative dimensions of letters connections pen movement writing skill and finger dexterity Kendall/Hunt

20 Other Variations in Handwriting Characteristics
Chapter 15 Other Variations in Handwriting Characteristics The arrangement of the writing on the paper such as margins, spacing, crowding, insertions, and alignment. Spelling, punctuation, phraseology, and grammar can be personal and help to individualize the writer. Furthermore, the writing style of one individual may be altered beyond recognition by the influence of drugs or alcohol. Kendall/Hunt

21 Handwriting Comparisons
Chapter 15 Handwriting Comparisons No single handwriting characteristic can in itself be taken as the basis for a positive comparison. The final conclusion must be based on a sufficient number of common characteristics between the known and questioned writing samples. There are no hard and fast rules for a sufficient number of personal characteristics; it is a judgment call made by the expert examiner in the context of each case. Kendall/Hunt

22 Chapter 15 Handwriting Samples The subject should not be shown the questioned document The subject is not told how to spell words or use punctuation The subject should use materials similar to those of the document The dictated text should match some parts of the document The subject should be asked to sign the text Always have a witness Kendall/Hunt

23 Handwriting Exemplars
Chapter 15 Handwriting Exemplars The collection of an adequate number of known writings (exemplars) is most critical for determining the outcome of a handwriting comparison. Known writing should contain some of the words and combination of letters present in the questioned document and be adequate in number to show the range of natural variations in a suspect’s writing. The writing implement and paper should also be alike. The writing of dictation and several pages may serve to minimize attempts at deception. Kendall/Hunt

24 Handwriting Exemplars
Chapter 15 Handwriting Exemplars Genuine Mickey Mantle signature SIMULATED FORGERY : made by copying an actual model or a mental image of a genuine signature. This is a traced signature done following a genuine signature or overlaying a genuine signature and using transmitted light to follow the line of writing. Kendall/Hunt

25 Chapter 15 *Methods of Forgery Simulated forgery : one made by copying a genuine signature Traced forgery : one made by tracing a genuine signature Blind forgery : made without a model of the signature Kendall/Hunt

29 Famous Forgers + Forgeries
Chapter 15 Famous Forgers + Forgeries Major George Byron (Lord Byron forgeries) Thomas Chatterton (Literary forgeries) John Payne Collier (Printed forgeries) Dorman David (Texas Declaration of Independence) Mark Hofmann (Mormon, Freemason forgeries) William Henry Ireland (Shakespeare forgeries) Clifford Irving (Howard Hughes forgery) Konrad Kujau (Hitler Diaries) James Macpherson (Ossian manuscript) George Psalmanasar (Literary forgery) Alexander Howland Smith (Historical documents) Kendall/Hunt

30 Collecting Handwriting Exemplars
Chapter 15 Collecting Handwriting Exemplars Generally, material written within years of the disputed writing is satisfactory for comparison. Why? For most adults, basic writing changes are comparatively slow. Kendall/Hunt

31 Collecting Handwriting Exemplars
Chapter 15 Collecting Handwriting Exemplars Gilbert v. California , Supreme Court uphheld the taking of exemplars before the appointment of counsel. Also ruled that handwriting samples are identifying physical characteristics that lie outside Fifth Amendment protection. United States. v. Mara, Supreme Court ruled that taking a handwriting sample did not violate Fourth Amendment rights (unreasonable search and seizure) Kendall/Hunt

32 Chapter 15 Forensic Linguist Experts that look at the linguistic content (the way something is written) of a questioned document. Language that is used can help to establish the writer’s: • age • level of education • gender • professional training • ethnicity • ideology Kendall/Hunt

33 Typewriters and Printing Devices
Chapter 15 Typewriters and Printing Devices The two requests most often made of the examiner in connection with the examination of typewriters and printing devices are: whether the make and model of the typewriter and printing devices used to prepare the questioned document can be identified. whether a particular suspect typewriter or printing device can be identified as having prepared the questioned document. In order to do this, the individual type character’s style, shape, and size are compared to a complete reference collection of past and present typefaces. Kendall/Hunt

34 Characteristics From Use of Typewriters and Printing Devices
Chapter 15 Characteristics From Use of Typewriters and Printing Devices As is true for any mechanical device, use of a printing device will result in wear and damage to the machine’s moving parts. These changes will occur in a fashion that is both random and irregular, thereby imparting individual characteristics to the printing device. The document examiner has to deal with problems involving business and personal computers, which often produce typed copies that have only subtle defects. Another area of investigation relates to the typewriter ribbon, which may contain type impressions. Kendall/Hunt

35 Chapter 15 Digital Technology In the cases of photocopiers, fax machines, and computer printers an examiner may be called on to identify the make and model of a machine or to compare a questioned document with test samples from a suspect machine. A side by side comparison is made between the questioned document and the printed exemplars to compare markings produced by the machine. Examiners compare transitory defect marks, fax machine headers, toner, toner application methods, and mechanical and printing characteristics. Kendall/Hunt

36 Photocopiers Transitory defect marks can develop from debris on
Chapter 15 Photocopiers Transitory defect marks can develop from debris on the glass platen inner cover mechanical parts These defect marks can become points of comparison Kendall/Hunt

37 Chapter 15 Fax Machines TTI (transmitting terminal identifier) header is at the top of each fax page Identifies where the fax originated from The TTI and the document’s text should have different type styles TTI can be fradulently made and put in the proper position on a fax copy. Detected by a microscopic examination Kendall/Hunt

38 Determining Fax Machine’s Model Type
Chapter 15 Determining Fax Machine’s Model Type Start by analyzing the TTI type stle Fonts are determined by the sending machine Number of characters, their style and their position in the header are best evaluated by checking a collection of TTI fonts in a database, such as from the American Society of Questioned Documets Examiners database Kendall/Hunt

39 Chapter 15 Do A House Divided Lab Hand out 6 shredded documents in zip lock baggies with the lab sheet. When you have completed putting a document back together, let the teacher check it and then put in back in its proper numbered baggie. Start another document. Kendall/Hunt

40 Determining Computer Printer Model
Chapter 15 Determining Computer Printer Model Requires extensive analysis of specific printer technology and type of ink used. By visual and microscopic techniques Character shapes, toner differentiation and toner application methods are determined with a low-power microscope Toner analysis involves identification of inorganic and organic components of the toner Printers are usually either: Impact prints EX. Thermal and dot-matrix printers Nonimpact printers EX. Ink jet printers and laser printers Kendall/Hunt

41 Typewriters TWO questions to ask:
Chapter 15 Typewriters TWO questions to ask: Can the make and model of the typewriter used to type the questioned document be identified? ° Need a complete reference collection of past and present typefaces used by typewriter manufactures. Can a particular suspect typewriter be identified as having prepared the questioned document? ° Need to compare questioned document to exemplars prepared form the suspect typewriter *** May also look at the ribbon to check the type impressions left on it Kendall/Hunt

42 IV. Alterations, Erasures, and Obliterations
Chapter 15 IV. Alterations, Erasures, and Obliterations Documents are often altered or changed after preparation, to hide their original intent or to perpetrate a fraud (forgery). Kendall/Hunt

46 IV. Alterations, Erasures, and Obliterations
Chapter 15 IV. Alterations, Erasures, and Obliterations OBJECTIVE: List some of the techniques document examiners use to uncover: alterations, erasures, obliterations, and variations in pen inks. Kendall/Hunt

47 “U.S. Take over of the Amazon Forest” Myth
Chapter 15 “U.S. Take over of the Amazon Forest” Myth Since 2000, a forgery has circulated falsely claiming that the United States and the United Nations have assumed control of the Amazon rainforest in order to safeguard its treasures for all mankind. Kendall/Hunt

48 IV. Alterations, Erasures, and Obliterations
Chapter 15 IV. Alterations, Erasures, and Obliterations Document examiners must deal with evidence that has been changed in several ways, such as through alterations, erasures, and obliterations. Erasures by rubber erasers, sandpaper, razor blade or knife to remove writing or typing disturb the fibers of the paper and are readily apparent when examined with a microscope. If an alteration is made to a document with ink differing form the original, it can sometimes be detected due to differences in the luminescence properties of the inks. Obliteration of writing by overwriting or crossing out to hide the original writing can be revealed by infrared radiation, which may pass through the upper layer of writing while being absorbed by the underlying area. Kendall/Hunt

49 IV. Alterations, Erasures + Obliterations
Chapter 15 IV. Alterations, Erasures + Obliterations Documents are often altered or changed after preparation, to hide their original intent or to perpetrate a fraud (forgery). ERASURES: The removal of writing, typewriting, or printing from a document, normally accomplished by either chemical means or an abrasive instrument. OBLITERATION: Blotting out or smearing over writing or printing to make the original unreadable. Kendall/Hunt

50 ERASURES Various methods used to erase parts of a document:
Chapter 15 ERASURES Various methods used to erase parts of a document: Using an India rubber eraser Sandpaper A razor blade or knife to remove writing by abrading or scratching the paper’s surface Detected by microscopy: Using direct light Using side lighting (let light strike paper obliquely from one side) Although microscopy detects erasure, it may not indicate the original letters or words present. WHY? Too much of the paper has been removed Kendall/Hunt

51 ERASURES Detected by microscopy: Using direct light
Chapter 15 ERASURES Detected by microscopy: Using direct light Using side lighting (let light strike paper obliquely from one side) Although microscopy detects erasure, it may not indicate the original letters or words present. WHY? Also detected by infrared luminescence — WHY? Too much of the paper has been removed Infrared luminescence reveals invisible residues of the ink that remained embedded in the paper. Kendall/Hunt

52 OBLITERATIONS Words may be obliterated by chemicals Detected by
Chapter 15 OBLITERATIONS Words may be obliterated by chemicals Strong oxidizing agent put on the ink produces a colorless reaction product Detected by microscopy -reveals discoloration of the treated area under the paper Ultraviolet (UV) or Infrared (IR) lighting - may reveal discoloration of the treated area under the paper Kendall/Hunt

53 Chapter 15 OBLITERATIONS Illuminating a document with infrared (IR) light and recording the light reflected off the document with IR sensitive film allows the examiner to differentiate between different inks. (due to their ability to absorb IR light) NOTE: If the overwriting is done with the same ink as used in the document, it is difficult if not impossible to detect. Intentional obliteration of writing by overwriting or crossing out is rarely used fraudulently. Kendall/Hunt

54 How to Determine what was written on Charred Documents?
Chapter 15 How to Determine what was written on Charred Documents? 1. Infrared photography 2. Reflecting lighting off the paper’s surface at different angles in order to contrast the writing against the charred background. Fig , p. 569 3. Digital imaging — Digitize the image by a scanner or a digital camera and then adjust by an image-editing program (ex. Adobe Photoshop) by lightening, darkening and color and contrast controls. Kendall/Hunt

55 V. Other Document Problems
Chapter 15 V. Other Document Problems In certain situations, indented writings (partially visible depressions underneath the visible writing) have proved to be valuable evidence. It may be possible to determine what was written by the impressions left on a paper pad. Applying an electrostatic charge to the surface of a polymer film placed in contact with a questioned document will visualize indented writings. A study of the chemical composition of the ink used on documents may verify whether or not known and questioned documents were prepared by the same pen; and the paper itself may be analyzed. Kendall/Hunt

56 INDENTED WRITING (Fig. 16-13 +14 p. 572)
Chapter 15 INDENTED WRITING (Fig p. 572) Are impressions left on paper positioned under a piece of paper that has been written on Detected by: 1. Oblique or side lighting 2. Electrostatic detection apparatus (ESDA) apply electrostatic charge to surface of polymer film touching the questioned document, then add toner powder to reveal indented writing Kendall/Hunt

57 Chapter 15 INK COMPARISON How to determine whether the ink on the known and questioned document came from the same pen? Visible microspectrophotometer (see p. 250 Fig. 7-11) Chromatography (method that physically separates the components of inks 1. TLC — thin-layer chromatography (p. 574 Fig ) • U.S. International Ink Library — collection of more than 8500 inks maintained by the U.S. Secret Service and IRS (dates from 1920s with new pen and ink formulations added yearly) 2. Paper Chromatography 3. Tagged inks (U.S. Treasury Department’s voluntary tagging programs of manufacturers dates ink to an exact year) Kendall/Hunt
