Abstract. Bone growth plates that close as a person ages, The lowest part of the pubis, worn down with age, Fissures in the cranium that close as a person ages. Determination of Race from the Skeleton through Forensic As forensic science continues to advance, hopefully these unidentified people can be identified, bringing closure to their loved ones. Full profiles were obtained on 65 samples (92.8%), partial profiles were obtained for 2 samples (2.8%), and no profiles were obtained for 3 samples (4.3%). Metric techniques have also been used to determine race from the skull. 0000006041 00000 n 1996 Apr 11;380(6574):484-5. doi: 10.1038/380484a0.
