What do questioned documents evidence examples include?

Questioned documents evidence encompasses a variety of items that can provide information about the authenticity of documents or signatures, as well as the intent of the issuer. In this context, credit cards serve as a type of questioned document because they contain personal information and a signature or imprint that can be analyzed. Forensic experts can examine the card's features, its issuance, and even any signatures it bears to confirm its validity or uncover potential forgery.

While GPS devices, cartridge cases, and gunshot residue can all play significant roles in criminal investigations, they do not fit within the conventional definition of questioned documents. GPS devices are typically used for tracking movements, cartridge cases are associated with firearms and ballistics analysis, and gunshot residue relates to the presence of residue on a shooter’s hands after firing a weapon. None of these items typically involve a document-related investigation in the same manner as credit cards.
