Title: JS 113: Questioned Documents


1
JS 113 Questioned Documents
  • I. Learning Objectives (C16)
  • Define Questioned Document and list common
    individual handwriting characteristics
  • List important guideline for collection of known
    writings and precautions to minimize deception
    during collection of exemplars
  • List class and individual characteristics of a
    typewriter and describe proper collection of
    typewritten exemplars
  • List techniques utilized for uncovering
    alterations, erasures, obliterations and pen ink
    variations
  • Describe 3 parameters of speech that a voice
    print represents

2
Questioned Document
  • Any object (paper, walls, windows, doors)
    containing hand writing or typewritten markings
    whose source or authenticity is in doubt
  • e.g. Letters, checks, drivers licenses,
    contracts, wills, voter registrations, passports,
    petitions, lottery tickets

3
Types of Document Evidence
  • LATENT
  • Indented writing
  • Fingerprints
  • Saliva (DNA)
  • Watermarks
  • Erasures
  • PATENT
  • Handwriting
  • Physical Match
  • Rubber stamps
  • Obliteration
  • Machine produced

4
Document examiner goals
  • Ascertain source or authenticate the QD
  • Uncover efforts at alterations
  • Reconstruct written contents of charred or burned
    paper
  • Uncover meaning of indented writings found on a
    paper pad after the top sheet has been removed
  • Gathering documents of known authorship or
    origin- critical to outcome

5
Handwriting Comparisons
  • No two individuals write exactly alike
  • Students start by copying (look similar- two
    systems used are Palmer and Zaner-Blosser)
  • As writing becomes subconscious then it becomes
    individualized. Unconscious handwriting of two
    different individuals can never be identical
  • Variations due to angle, slope, speed, pressure,
    letter and word spacings, relative dimensions of
    letters, connections, pen movements, writing
    skill, and finger dexterity.
  • Other factors include arrangement on the paper,
    margins, spacind crowding, insertions alignment,
    spelling, punctuation phraseology and grammar

Hand writing

Handwriting Comparisons
  • No single point or characteristic by itself can
    be used for positive comparison
  • Final conclusion needs to be based on significant
    points of comparison
  • The number is subjective with judgment made by
    the expert examiner only in the context of each
    particular case

8
Challenges to Handwriting examiners
  • Insufficient number of known writings with not
    enough personal characteristics persent in the
    known writings consistent with QD
  • QD contains only a few words all unnatural
    deliberately crude theratening letters
  • Writing habits may be altered due to drugs or
    EtOH
  • However it is difficult to maintain false writing
    habits when writing a large document
  • Illustrated in Howard Hughes/Clifford Irvings
    forgery

9
Forged signatures of Howard Hughes and examples
of Clifford Irvings writing
10
Collection of Handwriting Examples
  • Collection of adequate samples of known writings
    or exemplars is critical
  • Exemplars with similar or alike pens and paper
    should be used (if QD is ruled, then exemplar
    should be done on ruled paper)
  • Need to have adequate number of exemplars to show
    natural variation. No 2 specimen of writing by
    one person are identical in every detail (this
    can be used if forgery is traced)
  • Temporal aspect is important- within 2-3 years
  • In some cases, may need to obtain voluntarily or
    under court order.

11
Case law supporting constitutionality of taking
handwriting examples
  • Gilbert v. California 388 U.S. 263-1967- take
    handwriting exemplars before the appointment of
    counsel handwriting exemplars outside of the
    protection privilege of the Fifth Amendment
  • US v. Mara 410 U.S. 19- 1973- did not
    constitute an unreasonable search and seizure-
    did not violate Fourth Amendment

12
Minimize conscious efforts to alter writing while
taking exemplars
  • Get lots-text no shorter than a full page
  • Dictation yields best exemplars and should take
    place at least 3 times. If faking, 3 replicates
    will not match. Need to repeat
  • Make writer comfy without distractions
  • Never show QD or provide instructions on
    spelling, punctuation or case to use
  • Have pen and paper similar to QD
  • Text should contain contents or at least have
    words, phrases and letter combinations in the QD
  • Signature exemplars should be combined with other
    writings eg checks
  • Document examiner should be consulted and shown
    the QD before requested exemplars are taken

13
Typescript Comparisons
  • Typewriters Can the make and model of the
    typewriter used to type the QD be identified
  • Can a particular suspect typewriter be identified
    as having prepared the QD
  • Two most popular typefaces are pica (10 letters
    per inch) and elite (12 letters per inch)
  • Individual characteristics imparted due to wear
    and tear on moving parts. Variation in alignment
    as well as defects in each typeface are useful
    for individualization
  • Type impressions left on a ribbon may make it
    possible to find the portion of the ribbon on
    which a particular text was typed

14
Typewriting
15
Exemplars for typewriter Comparisons
  • Need good exemplars from the known typewriter
  • Exemplars are needed either directly from the
    typewriter in question or indirectly from
    gathering known writings that have been typed on
    the suspect machine (temporal aspect
    important-why?)
  • Minimum of one copy in full word for word order
    of the wuestioned type writing obtained

16
Photocopier, printer and Fax examination
  • Make and model of a machine used in printing
  • Compare a QD to a test sample or exemplar from a
    suspect machine
  • Generate 10 samples through each machine to
    obtain sufficient representation of photocopiers
    characteristics
  • Side by side comparisons made between QD and
    printed example to compare markings
  • Transitory defect marks due to debris on glass,
    inner cover or mechanical protions of a copier
    produce images- irregularly shaped and sometimes
    form distinct patterns
