READ: Forgeries and Handwriting Analysis

Introduction

A questioned document is any document whose authenticity is in question. The questioned documents unit in a forensic lab will conduct examinations of documents and related materials in all types of criminal cases for local, state, and federal agencies. This includes the examination of writing, ink, paper, impressions, typewriting, faxes, photocopiers, alterations, obliterations, charred, forgeries, and counterfeited items to name a few. Another division of Forensics, known as Computer Forensics involves the scientific examination and analysis of data held on, or retrieved from, computer storage media in such a way that the information can be used as evidence in a court of law.

Essential Questions

1. Is handwriting class or individual evidence?

2. How can ransom notes or suicide letters be helpful to forensics scientists?

3. What security measures are taken to prevent counterfeiting?

4. What type of documents can be forged?

5. What is Computer or Digital Forensics?

In today's digital age, communication is increasingly dependent upon computers and devices. While not a paperless society, we are certainly much more likely to utilize digital forms of documentation and communication than ever before. While there has been a decrease in the use of paper documentation, it is still the standard in many sectors of society and business, and thus questioned document examiners are needed. Whether it involves a ransom note, an alleged forgery of a will or some other contested document, questioned document examiners' main focus is to evaluate the authenticity of suspicious documents. Document examiners look for signs such as erasures, obliterations or other alterations using various analytical techniques such as chromatography and oblique lighting. Computer or Digital Forensics involves investigating the data stored on computers and devices for evidence of a crime. Ranging from questionable Internet searches about how to dispose of bodies to white collar crimes like embezzlement, Computer Forensics often uncovers important clues that even the most meticulous perpetrators may think are hidden.
