U.S. Mississippi Death Row Case Faults Bite-Mark Forensics

SEPT. 15, 2014

Mr. Bundy was found guilty and the obscure field of “forensic dentistry” won a place in the public imagination.

Since then, expert testimony matching body wounds with the dentition of the accused has played a role in hundreds of murder and rape cases, sometimes helping to put defendants on death row.

But over this same period, mounting evidence has shown that matching body wounds to a suspect’s dentition is prone to bias and unreliable…..

The lack of a scientific basis for bite-mark identification was stressed by the National Academy of Sciences in a 2009 report on forensics. The academy said that such analysis could not reliably identify one individual, among all others, as the source of a bite.

Bite marks on the skin change over time and are easily distorted, the academy said, while there is a huge potential for bias when an expert is asked to match a bite wound with the teeth of a known suspect.

Dr. Peter W. Loomis, a consultant in dental forensics in Albuquerque and president of the discipline’s professional body, the American Board of Forensic Odontology, did not dispute the academy’s conclusions but said that bite-mark analysis still had a useful role in court.
