She and two other students presented their research to a worldwide virtual audience of academics and students.
Tempest based her research on 2019 figures from the Johannesburg Forensic Pathology Services (FPS) medico-legal mortuary in Hillbrow.
This facility sees a huge number of unnatural deaths, receiving between 3,500 to 4,000 bodies a year.
In her presentation, Tempest warned that as Hillbrow and south Johannesburg were densely populated by foreigners, they had potential to skew the findings.
In 2019 the Johannesburg FPS saw 3,550 deaths, with 693 of those, just more than 19%, being non-South Africans. For her research she did not include unidentified bodies or foetuses.
