Forensic Document Examination

The Forensic Document Examination section examines original handwriting specimens from a variety of crimes, including but not limited to forgeries, suicide/homicide, threatening correspondence, fraudulent documents, sexual assault, etc. Other types of analysis include: typewriter examination (paper fiber transfer, wear patterns, and fracture patterns), photocopier comparisons, and ink comparisons (both destructive and non-destructive), rubber stamp comparison, trash bag comparisons, latent writing restoration, and obliteration restoration. All questioned exhibits must be accompanied by known standards (or exemplars).

ATTENTION – For information regarding the collection/handling of evidence, and other considerations in this discipline, please refer to the Laboratory Customer Handbook (excerpt from Crime Laboratory Service Manual) (PDF) for specific instructions.
