Document Examination Forensic Document Examination involves the analysis and comparison of questioned documents with known material in order to identify whenever possible, the author or origin of the questioned document. Chapter 15 Kendall/Hunt Publishing Company 9
Collection the “Knowns” )Exemplar – An authentic sample used for comparison purposes such as handwriting )Obtaining an adequate number is critical in the outcome of the analysis )No two specimens are ever identical in every detail due to natural variations (the normal deviations found between repeated specimens) ) Chapter 15 Kendall/Hunt Publishing Company 10

Is the spacing between words and letters consistent in the questioned and the known? ) Ratio of relative height, width, and size of letters: What are the overall height, width, and size of letters in both the known and questioned documents? Are they consistent? Chapter 15 Kendall/Hunt Publishing Company 13
Closer look continued. ) Pen lifts and separations: Check how the writer stops to form new letters and begin words. ) Connecting strokes: Compare how capital letters are connected to lowercase letters and how strokes connect between letters and words ) Beginning and ending strokes: How does the writer begin words, numbers, or letters and how are they ended? ) Unusual letter formation: Look for letters written backwards, letters with tails or unusual capital letters Chapter 15 Kendall/Hunt Publishing Company 14
