Questioned Documents 1Questioned Documents 1

Scope of the ScienceScope of the Science

• Generally concerned with three major subjects– Hand written documents– Mechanically generated documents

• Typewriters• Printers• Faxes• Photocopiers

– Voice examinations

Questioned Document CrimesQuestioned Document Crimes

• Forgeries– Wills, contracts, insurance policies,

signatures– Currency– Antiques, old books, writings

• Ransom notes, kidnapping, and violent crime

• Phone conversations, threats, etc.

Handwriting AnalysisHandwriting Analysis

• Most questioned document crimes involve some type of handwriting analysis

Nature of HandwritingNature of Handwriting• Unique to an individual

– Based upon a careful communication between brain, multiple muscles, senses, timing, and feedback through the same chain• Even the same person can not exactly

duplicate his/her own style with 100% accuracy

– Impossible to exactly duplicate handwriting since it requires an understanding of the process described above

External FactorsExternal Factors

• Writing instrument

• Writing surface

• Writing situation (this creates variety in a single individual)

• Special circumstances: drugs, injury, stress, conscious change

CharacteristicsCharacteristics

• Handwriting contains both class and individual characteristics– Basic penmanship, cultural symbols, etc.

(class characteristics)– Individual characteristics develop after

years of writing

• Best evidence is obtained when working with the original document

Handwriting LimitationsHandwriting Limitations

• Requires expert analysis to work as evidence– Often includes use of microscopes,

cameras, and computers

• Description of Personality– Known as “graphology”

• Considered different from questioned documents and represents an entirely different field of study

GraphologyGraphology

Which person is crazy?

Elvis Presley

Adolf Hitler

Handwriting LimitationsHandwriting Limitations• Cursive vs. printed

– Can sometimes be compared if writer has characteristics that carry over into both forms

• Foreign Languages– Cultural nuances of written language must

be understood• “Diacritics” (distinguishing strokes)• Shading of certain characters (Asian)

Handwriting MythsHandwriting Myths

• Can not determine “handedness”

• Can not determine gender

• Can not determine age

Handwriting and the LawHandwriting and the Law

• (1967) Obtaining handwriting samples is legal before lawyers are present– Does not violate Fifth Amendment (includes self

incrimination) since it was deemed a physical characteristic of the person

• (1973) Handwriting samples are not considered a violation of the Fourth Amendment (Illegal Search and Seizure)– Failure to comply may result in Contempt charge

Handwriting SamplesHandwriting Samples• Best to acquire a large number of samples

from a suspect (known as “exemplars”)• The more samples available, the more the

natural variation of the suspect can be identified

• Documents of approx. 2-3 years old are acceptable for most adults– Writing styles in children change much faster

• Samples can be obtained voluntarily or by court order

Handwriting SamplesHandwriting Samples

• Samples should be as alike as the document in question– Includes type of paper, pen/pencil, etc.

• Styles and habits can naturally change for different types of documents and instruments

• Samples should contain at least some of the same words and combinations of letters as the questioned document

Minimizing DeceptionMinimizing Deception

• Desired sample should be dictated

• Writer should be comfortable without distractions

• Writer should not be shown the questioned document or assisted with punctuation, spelling, etc.

Minimizing DeceptionMinimizing Deception

• Writing instrument should be similar to questioned document

• Dictated text should be close to questioned document or contain the same phrases and/or words

• Multiple uses of same words can help establish variations

Handwriting ForgeriesHandwriting Forgeries

• Blind– Forger uses own handwriting– Easiest to detect

• Simulated– Forger copies a genuine signature– Much harder to detect but requires considerable

effort to achieve

• Traced– Forger traces a genuine signature

Detecting ForgeriesDetecting Forgeries

• Inconsistencies in handwriting style or techniques are the key
