McNamara was found “twisted in rope” and in critical condition at the back of the yacht, which had docked on an island called Kefalonia. She died while being transported to the hospital.
In an Instagram post last month, McNamara, who’s from New South Wales, said she was “living & working on a boat seeing all that the world has to offer.” News.com.au reports she had been employed on the Mayan Queen IV for four months.
According to BBC, the yacht belongs to Alberto Bailleres, a Mexican businessman who runs a mining conglomerate. Bailleres and his family had not been onboard for several days before McNamara was found.
The Daily Telegraph reports that McNamara’s cousin said her family doesn’t know the cause of death but have speculated that it was accidental. Her mother and sister were on their way to visit her before she died.
