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.

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
