The mystery surrounding the death of a 20-year-old Australian Instagram model has deepened.
Sinead McNamara was found dead on Friday in Greece on board a superyacht.
McNamara had been working on the Mayan Queen IV, a US$140 million, 92 metre yacht, owned by Mexican mining magnate Alberto Baillères.
Local media reports Baillères had left the boat on Tuesday and Sinead was left onboard with the rest of the boat crew.
Her body was reportedly found at the back of the boat.
"The Coast Guard of Kefalonia has ordered an investigation into the circumstances that led to the death of the 20-year-old Australian national as well as an autopsy-necropsy," In Kefalonia reported.
