The authors present a case of identification of a a murderer on the basis of his dentition pattern, reflected by a biting wound on the breast of the victim. The case is exceptional not only from the viewpoint of the authors, but also in view of very sporadic reports on this subject in forensic literature. Cases of biting by humans are not frequent in the forensic/medical practice, and instances of identification of the perpetrator by his dental pattern reflected in the biting wound are very rare. In Poland, such problems have been the domain of mainly criminologists and only occasionally of forensic medics in collaboration with dentists and anthropologists. Due to the very low number of such cases in Poland, no experts in the matter are available. For this reason, we deemed it purposeful to present respective investigative principles and techniques for identification of a human perpetrator on the basis of the dental pattern reflected in a biting wound on the victim’s body.
