Forensic Document Examiner – Certified.

Sample Cases

“Cut & Paste” Process:

The image shows three overlaid signatures, purportedly signed by a client on separate documents.  The ability for a person to sign their name precisely the same way twice or more, has not been encountered by document examiners.  Writing is a product of our motor skill capability.  Although signatures may display a close similarity, we do not have the machine-like ability to sign our name multiple times with exact alignment.

As you can imagine, such fabrications may be accomplished with a photocopy machine or with the use of imaging software such as PhotoShop.

I prefer to examine original documents, if they are available.  The possibility of a ‘cut and paste’ of a signature, or other text, onto a document cannot be excluded by an examination of a non-original document.

Other evidence of a fabrication encountered in my examinations include portions of a baseline, numerals and “trash marks” (extraneous marks caused by a photocopier). 

Obliterating Fluid Alteration:

A product, such as LiquidPaper©, is a common method to cover text or other writing on a document. The information remains absent or, in the majority of cases, is modified in favor of the person making the alteration.  Evidence of an obliteration includes the two items shown below, from a receipt related to an insurance fraud.

Altered dollar amount:

The original dollar amount was altered with a pen having similar colored ink.  Special instrumentation (used to examine ink in the infrared light spectrum), clearly revealed the use of a second pen having a different ink formula.  The instrument is useful in detecting alterations in medical records, ledgers, checks, contracts, etc.  The instrument also served to show ‘patching’ strokes were made with a different pen in a signature case.

If you suspect a document was altered in some manner, contact me so I may discuss with you how the issue may be resolved.
