Questioned Documents in Complex Cases

"I have personally worked with Patricia on a very complicated case that was litigated in Contra Costa County. She was a great help to my client an the Court in analyzing documents and giving testimony." ... She had a PowerPoint presentation that explained how she arrived at her expert opinion and conclusions. We were very fortunate to have her participate in this case. I highly recommend Fisher Forensic Documentary Laboratory and would use these services again."

Cases can involve many different types of documents and printing processes. It is critical that the document examiner have the experience and the equipment to document the results. 

Common types of documents that become in question in complex cases

  • National and international business and financial transactions using documents from multiple sources (i.e., hard copies of emails, wire transfers, facsimiles, machine copies of letters and financial documents, etc.)
  • Alterations of already existing documents and the creation of new documents using multiple sources
  • Hate crimes where writing is often on walls or other objects and written with spray paint or markers. These cases often have multiple suspects
  • Anonymous writings in larger business settings where there may be multiple suspects and dozens or hundreds of employees
  • Documents written using other writing systems such as Farci, Arabic, Chinese characters, as examples.

Case Study – The grandson recreated over 20 years of corporate minutes to take over his grandmother’s business

The grandson tried to take over his grandmother’s business by recreating the corporate minutes from the early 1990’s through 2013.  By 2013, the grandson had transferred all the stock to himself. With the aid of our equipment, examinations with a stereo-zoom microscope and high definition camera, a Video Spectral Comparator 40/HD with functions. These were used to examine inks, paper a newly created corporate seal, and an ESDA (Electrostatic Detection Apparatus) to analyze indentations proved that the minutes to take over the corporation were fabricated.

Case study 2 – A gang used multiple methods to defraud the bank

In the second case (not illustrated) before Ms. Fisher was to testify for the prosecution, a gang pled to a bank fraud. The fraud involved home equity checks sent to home owners to transfer over $800,000.00 to new accounts.  This was a complex case involving multiple examinations. The documents in question included signatures, handwriting, fabricated and genuine checks that included fabricated and genuine logos, facsimile documents from different sources, and word processed letters to authorize transfers.  The perpetrators used some of the same technics from earlier check frauds where more than one person would write a check to throw off investigations.

Additional types of documents, signatures and writing that come into question in complex cases:

  • Landlord / tenant agreements, receipts
  • Criminal  – financial documents, hate crimes, anonymous writings such as kites
  • Immigration – identification documents such as birth certificates and marriage licenses
  • Medical records – handwriting or interlineations in computerized records
  • Diaries to prove the amount of overtime the employee claims to have worked,
