How do forensic scientists analyze handwriting samples in forgery cases?

Forensic scientists play a crucial role in analyzing handwriting samples in forgery cases to uncover fraudulent documents. They utilize various techniques to examine the authenticity of the handwriting and the document as a whole. Here are some common methods used in handwriting analysis:

Handwriting Examination

Forensic experts compare the questioned handwriting with known samples to identify similarities or inconsistencies. They look at the size, slant, spacing, pressure, and overall style of the writing to determine if it is consistent with the suspected writer.

Ink Analysis

Forensic scientists analyze the ink used in the document to determine its composition and age. Changes in the ink's chemical composition can indicate alterations or additions to the document, raising suspicion of forgery.

Electrostatic Detection

This technique is used to reveal indented impressions left on a piece of paper from previous writing. By applying an electrostatic charge and a powder, forensic scientists can unveil hidden writing that was later erased or covered up.

By employing these forensic techniques, experts can effectively analyze handwriting samples in forgery cases and provide valuable evidence in legal proceedings.
