Vocabulary

B. Method 1: Handwriting Analysis1. By using characteristics of a

known handwriting sample, document examiners can often detect forgeries

2. Handwriting analysis also allows forensic scientists to make matches between a document and the author

Methods for Detecting Forgeries

f. Unusual letter formationg. Shading or pen pressureh. Slant i. Baseline habitsj. Flourishes or embellishmentsk. Diacritic placement

a. Line qualityb. Word and letter

spacingc. Letter comparisond. Pen liftse. Connecting,

beginning and ending strokes

Method 1: Handwriting Analysis3. The following characteristics are often used in conducting handwriting analysis (review of previous material):

• The Zodiac Killer was never caught, but Ray Allen was the prime suspect. Do the samples match?

Handwriting Analysis Example

• Jon Benet was a child beauty pageant star. The-six-year-old’s body was found in the basement of her family home nearly 8 hours after she was reported missing. A ransom note was found on the kitchen staircase. Her family’s involvement in the murder is still unknown. The case was re-opened in 2010 as no one has yet been convicted and there is new technology in DNA, etc. now available.

B. Method 2: Typed Document Analysis1. Some criminals use computers or

typewriters in an attempt to avoid being caught through handwriting analysis

2. Fortunately, connections can still be made between a suspect and a document

3. Steps for analyzing typed documents:a. Identify and examine quirks (ex. Off-set or crooked letters), impressions on the paper, font style, font size and spacingb. Test ink using chemicals and different light sources to determine the composition and possibly the brand of the inkc. Test paper for composition and possible fingerprints

Method 2: Typed Document Analysis

Example of Altered Typed Documents

1. Chromatography: a technique used for the separation of mixtures from a solutionEx. Separating ink into individual color components

C. Method 3: Chromatography

2. Chromatography can be used on pen ink, typewriter ink and computer ink3. Chromatography can identify the composition and source (brand, factory) of the ink4. By knowing the composition and the source, scientists can then determine the age of the ink and if the ink is the same throughout the document
