Questioned Documents

The Questioned Documents Section of the Laboratory is staffed with a Forensic Document Examiner,  Board Certified by the American Board of Forensic Document Examiners.

Any problems concerning a document will be considered.  The term “document” is a general term for any substrate that is used to convey a message.  While the term “document” is generally considered a paper document, the “document” may be a box, wall, bathroom stall dividing partition or any other object.

Questioned Document problems commonly include the examination and comparisons of handwriting, typewriting, hand printing, printed materials, adhesives, inks, paper, rubber stamp impressions, alterations, eradications, obliterations, tampering, charred documents, photocopy processes, and counterfeit documents.  The examinations are conducted in the visible spectrum as well as the ultraviolet (254nm to 365nm) and the near infrared spectrum (700nm to 1100nm) when necessary.

The Questioned Document Section is equipped with state of the art instrumentation such as a Video Spectral Comparator and an Electrostatic Detection Device.
