A further investigation, in 2014, revealed that it was unlikely he had been killed in a chariot accident. Scans found that all but one of his bone fractures, including those to his skull, had been inflicted after his death. The scans also showed that he had a partially clubbed foot and would have been unable to stand unaided, thus making it unlikely he ever rode in a chariot; this was supported by the presence of many walking sticks among the contents of his tomb. Instead, it is believed that genetic defects arising from his parents being siblings, complications from a broken leg and his suffering from malaria, together caused his death.
