Evaluation of anatomical consistency in craniofacial superimposition images.
Using 52 skulls in forensic cases, the anatomical consistency of cranio-facial superimposition images was investigated for evaluating the validity in personal identification by the superimposition method. In 35 out of 52 cases the unknown skull was positively identified as the missing person by matching of the outline and anatomical relation in skull and face images taken from frontal, oblique and lateral directions. The unknown skull in two cases was exclusive of the presumed person since the outline of the skull was not anatomically consistent with that of the face. In the remaining 15 cases, the skull in question was examined using only a frontal face photograph of the missing person and matched with it because of the lack of other photographs taken from different angles, giving a probable identification. From our practical examination, it is stated that the outline from the trichion to the gnathion in the lateral or oblique view is the preferable portion for personal identification, and the cranio-facial super-imposition method is reliable for individualization when two or more facial photographs taken from different angles are used in the examination.
