'Similar scenarios could also create confusion around a victim’s identity — and in fact it has, said Yongbin Eom, a visiting research scholar at the University of North Texas Center for Human Identification. In 2008, he was trying to identify the victim of a traffic accident for the National Forensic Service in Seoul, South Korea. Blood showed that the individual was female. But the body appeared to be male, which was confirmed by DNA in a kidney, but not in the spleen or the lung, which contained male and female DNA. Eventually, he figured out that the victim had received a bone marrow transplant from his daughter.'
