Good Essays
Questioned Document Have you ever wondered how a document corresponds to a crime scene? Well it may be much more important than one must think. Questioned documents evidence has been around for ages, and is still used in understanding what occurred at a crime scene. However, the evidence must be properly cared for a preserved. A questioned document is defined as a document that is partly or entirely suspicious in regard to the authenticity or origin (James, Nordby, Bell).

Different types of tests are then ran on the submitted documents by a trained professional to decipher or restore the writing (Hilton, 1940). If identifying evidence is found on the documents, it can be used to marrow down suspects and produce the actor of the crime.

Since everyone has their own unique style of writing it would be rather simple to determine that this document was forged making questioned document collection, preservation, and examination an essential step in the investigation process. Therefore, collecting and preservation document are key elements in the processes of crime scene work. Even thought, this technique of evidence has been around for a while, it still proves to work wonders in the investigation process. Follow the necessary steps to be successful
