Abstrakt: The Johannesburg Forensic Pathology Services medico-legal mortuary perform postmortem examinations on all cases of unnatural deaths in the greater Johannesburg metropolitan area, in South Africa. Unidentified decedents can comprise up to 10.0% of the total number of annual admissions at this medico-legal mortuary. To address the identification of the deceased, the Human Decedent Identification Unit (ID Unit) was created to perform secondary examinations for identification purposes. The aim of this study was to report on the identification methods and success rate of the ID Unit. Over a period of 31 months (January 2018-July 2020), unidentified decedents comprised 8.1% (n = 693) of all cases at the Johannesburg mortuary. The ID Unit processed 385 (55.6%) unidentified individuals during this period, who were mostly adult (100%), Black (94.5%), males (91.7%). DNA samples were successfully collected from most cases in the form of hair (96.4%; n = 371), blood (92.2%; n = 355), and nail samples (90.1%; n = 347). Fingerprints retrieved in 65.5% of cases (n = 252). Ultimately, 87 persons (22.6%) were positively identified. Fingerprinting was the most successful method of identification (98.9% of cases; n = 86). One positive identification was facilitated through DNA analysis. The nationalities of the positively identified decedents were from South Africa (52.9%; n = 46), Zimbabwe (5.7%), Uganda (1.1%), Mozambique (1.1%), Malawi (1.1%), South Sudan (1.1%), and undisclosed in 36.8% of cases. Through the collaborative efforts of all the agencies involved, the impact of the work of this ID Unit is vast-not only for South African authorities but most importantly for the decedents and their families.
