Reliability of Craniofacial Superimposition Using Three-Dimension Skull Model

Forensic Summary by Emma-Rae Ranger

Using CT data with a computer aide 3D for superimposition techniques, a three dimensional laser scans and analyzes the resulting superimpositions. These impositions were then analyzed through craniofacial landmarks, morphological features, and the combination technique. Producing a 3D model of each of the five skulls that were initially scanned, the methods were put to the test using the 3D model. These skulls were also analyzed based on the sex of the human to see if there would be any statistical significance. Results showed that the use of craniofacial landmarks proved to get the most correct identifications with only 40% false positives. However, due to the high number of false positives the data suggests that none of the methods are good or admissible into a court room.
