Authorities on the Ionian island of Cephalonia are reportedly conducting an investigation into the death of a 20-year-old Australian woman, identified as a model and blogger, who passed away after first being discovered in critical condition aboard the yacht of a Mexican billionaire.
The woman died en route to a hospital aboard an aircraft.
In a report from Greece, the BBC said the incident occurred on Thursday.
The same news outlet said the mega-yacht belongs to Alberto Baillères. The victim was identified as Sinead McNamara.
Other press reports claimed that only crew-members were aboard the vessel, which has been ordered to remain docked at the port of Argostoli, when McNamara was discovered unconscious.
