Objectives: Determine the origin of a writing sample using the 12 exemplars
Document Examiners:Mostly examine handwriting to originate its source or its authenticity
Will also examine typed writings, computer printings, photocopies, inks, papers, and forgeries, and decode altered and charred documents
May need to use microscopes, photographs, chromatography, and other lab examinations on the questioned documents
Many work in federal, local, and state crime labs, but they may also work in private practices
Objectives: Determine the origin of a writing sample using the 12 exemplars
Handwriting:
Two individuals cannot have exactly identical handwriting
Since handwriting is associated with mechanical, physical, and mental functions, it is almost impossible to reproduce exactly
Handwriting can be almost as individual as a person’s fingerprint
Objectives: Determine the origin of a writing sample using the 12 exemplars
A positive comparison must be based on an ample number of common characteristics between known and questioned writingsCollecting a lot of exemplars (known writings) is critical in order to make a comparisonExemplars should contain some of the same words or combinations of letters that are present in the questioned document(s)
Objectives: Determine the origin of a writing sample using the 12 exemplars
Two writings came from one person if:
their similarities are unique and
no unexplainable difference(s) are found
1. Examine the questionable document for detectable traits and record them
2. Obtain a known sample of the suspect’s writing (an exemplar)
3. Compare and draw conclusions about the authorship of the questionable document
Objectives: Determine the origin of a writing sample using the 12 exemplars

Objectives: Determine the origin of a writing sample using the 12 exemplars
12 Handwriting Characteristics (Exemplars)

7) Cursive and printed letters: Are there printed letters, cursive letters, or both?
8) Pen pressure: Differing amounts of pressure used by the writer can make lines light or dark, narrow or wide. Is pressure equal when applied to upward and downward strokes?
Objectives: Determine the origin of a writing sample using the 12 exemplars
9) Slant: analyzing the writing slant- left, right, straight, or variable?
10)Line habits: are the writer’s letters on, above, or below the baseline?
Objectives: Determine the origin of a writing sample using the 12 exemplars
11)Fancy curls or loops: Are there any fancy letters, curls, loops, circles, or other embellishments?
