Unusual three-dimensional bite mark evidence in a homicide case.

A comparison has been made between bite marks observed on the nose of a female homicide victim and the configuration of the dental structures of a male suspect. The victim's bite marks showed a number of demonstrable characteristics which could be reproduced by models of the dentition of the suspect. Special peculiarities within and between individual teeth, together with the upper and lower jaw relationship, were demonstrably consistent with the bite mark patterns on the victim's nose. Detailed examination of the scientific evidence led the dental investigators to the conclusion that there was a positive match between the suspect's dentition and the bite mark on the decedent's nose. The dental investigation and subsequent dental testimony were prime factors leading to the defendant's conviction of manslaughter in the first case in California involving the major use of bite mark evidence.
