    When she was a girl, the young woman had emigrated with her family to the United States from her home country in Africa. She grew up in the northeastern USA and was now attending college. As part of her application for United States citizenship she must present her birth certificate. Her father sent the birth certificate to her. The birth certificate had apparent alterations. Government officials refused to accept the birth as valid because her appearance did not match the age on the birth certificate. She was born in 1994 yet birth certificate appears to state her year of birth as 1984.

    The divorce had been finalized 15 years earlier. The husband had moved on with his life. He was happily remarried and enjoying his retirement years. The ex-wife could not let go. She sued in the Superior Court of Los Angeles claiming the husband would not relinquish rights to real property and other interests that had been part of the divorce settlement.

    The decedent signed a life insurance beneficiary form a few weeks after having brain surgery. The plaintiff claimed the signature was not executed by the decedent. The defense claimed that the decedent had signed the document and the differences are attributed to the effects of brain surgery.

    As with any other profession, document examiners have a range of expertise and experience. As important as it is for your client to make a clear assessment of your abilities, it is up to you to determine in advance, with a high degree of accuracy, whether the document examiner you plan to hire will perform the most accurate assessments and be ready to back up those assessments with a scientifically repeatable methodology in court.

    None of us wants to feel that our opinions are tainted by bias. The ability to recognize when bias is an influence in an expert's opinion and the skill of an expert to overcome his or her biases is integral to an expert's credibility.

    The Most Dangerous Animal of All was co-written by the estranged son of California’s infamous Zodiac killer to reveal his father’s true identity. When the book hit the streets the skeptics were in full force. Just like those who mocked the boy who cried wolf, no one could blame them. Too many people had already claimed to either be the killer or to know who he really was.

    Forensic document examination, performed correctly, is a reliable discipline that can demonstrate the innocence of your client or the guilt of your opponent. Used strategically, it can help you settle out of court. When court is necessary, your document examiner can present a case so clearly that the outcome is beyond doubt. To achieve this, your document examiner must be proficient in the latest techniques and adept at reporting results.

    For forty years, PAUL KAYFETZ, INC. through Mr. Kayfetz' expert testimony, has routinely admitted the following into evidence:
  • Driverseye Visibility Studies
  • Night-Time Photography
  • Computer and Video Simulations
  • Accident Reconstruction Photos
  • Photogrammetry Photo Measuring

    Our computer engineers, video engineers and engineering photography experts:
  • Apply Accepted Engineering Measurements Procedures
  • Have Published Numerous Peer-Reviewed Engineering Papers
  • Use HD Video Systems that Produce Movie Theater Quality
  • Apply Cutting Edge Computer Techniques for Lifelike Photorealistic Images (not Computer Cartoons)
  • Coordinate with the Best Accident Reconstruction and Human Factors Experts for Technical Accuracy

    We frequently help plan complete technical testing, visibility study, computer simulation and demonstrative evidence strategy - coordinating a group of technical witnesses who are independently retained by counsel. This is requested by many clients because of Mr. Kayfetz' track record, his previous career as an attorney, his extensive contact with top experts from his forty years experience as an engineering photography consultant working with the best forensic witnesses on many of the major cases during those decades, and upon his membership and participation in major engineering societies.

    Each year we help attorneys win and save hundreds of millions of dollars in verdicts and settlements.

    This results primarily from our experience and expertise. It also stems from our ability to discover measurements from existing photos. We are ahead of everyone in our field because we invest in HD cameras costing 250,000 each, six figure computer systems, custom engineering computer programs and staff engineers - not artists.

    A major part of our work is evaluating and keeping out of evidence opponents' forensic photography, computer simulations, or computer animations which do not comply with the rules of evidence. This has swung multi-million dollar results several times in recent years.

A visibility study depicts what is available to be seen by a person with normal, unimpaired vision under defined conditions similar enough to those at issue to provide relevant information about levels of visibility, lines-of-sight, timing of visibility, and to demonstrate expert witness(es)' opinions.

    Jurors jumped as the wild boar in the motorcycle headlights suddenly filled the large screen in front of them.A week later they awarded the motorcyclist several million dollars against Caltrans for not mitigating a chronic wild pig problem on Highway One in Monterey County. The jury found that the motorcyclist had a 0.10 blood alcohol level and was negligent, but that our HD-video visibility study showed that even an unimpaired driver could not have seen the pig in time to avoid it.

    The objective of this article is to report on the integration of improved video and related computer technology into existing, long-accepted visibility study preparation and presentation methodologies. The result has been an incremental extension of the types of visual environments which can be reproduced with substantial similarity for admission as visibility evidentiary exhibits in court
