Bitemark Evidence Essentials: Current Research Findings covers the historical use and emerging concerns surrounding bitemark evidence, including the findings of recent reports critically evaluating the foundation of the bitemark evidence discipline. By contrasting bitemark evidence with other scientifically validated analysis methods, this webinar will present numerous research study considerations including how the flexible nature of skin, bite discrepancies, time factors, and wound healing affect the reliability of preserving and evaluating bite mark evidence. The presentation will cover case studies involving exonerations based on bitemark evidence as well as legal considerations attorneys should be aware of when encountering cases that include bitemark evidence.

Bitemark evidence has been presented in courts of law as early as the Salem witch trials. Precedent setting cases were tried in the United States in the 1970’s and the roller coaster ride began. High profile cases followed, such as Theodore Robert BUNDY v. FLORIDA, and there was no looking back. Bitemark evidence was securely entrenched in courtrooms across the U.S. The precedent setting cases were misleading, and the Bundy evidence was not infallible, but these cases were enough to open the door. A door that has been difficult to close despite numerous exonerations invalidating bitemark evidence and scientific research showing the deficiencies of this type of analysis.

This presentation will review this flawed history and debunk the two basic premises of bitemark analysis that: 1) the human dentition is unique, and 2) this uniqueness reliably transfers to human skin. Despite the problems with this form of pattern analysis it is still accepted in most jurisdictions within the U.S. Opposition to the use of this evidence has been strong but attempts to maintain the status quo is also vocal. Justice and common sense should prevail, but reform is a slow process. Education is the key to change. The goal in sharing this information with you is to prevent another innocent person becoming another falsely imprisoned statistic based on unreliable evidence.
