It is understood that this is the preliminary opinion of a coroner, who is waiting for toxicology tests that could take another month before finalising his verdict.
Greek coroner Ilias Bogiokas, who conducted the autopsy on McNamara’s body, told the Athens Macedonian News Agency that the model died from hanging and that the body did not have any injuries.
A report by the Guardian on Saturday quoted the coroner saying he was left with “doubts and questions” after conducting an autopsy on McNamara.
“The answer lies with the toxicological and histological tests,” Bogiokas told the Guardian.
“There was no evidence of ill-treatment … my verdict is death by hanging but there were signs that she may have tried to stop it.”
The family revealed on Friday that shortly before her death, Sinead called home crying and talked about an incident involving another crew member.
They strongly believe there were “strange” aspects to events on the yacht shortly before their daughter’s death, and want any investigation to fully reveal what happened.
According to the Greek news agency, initial evidence gathered by the coast guard, who took statements from about 23 crew members and examined CCTV video footage from the yacht, seemed to indicate McNamara took her own life, but the investigation has not been completed.
McNamara, from Port Macquarie in NSW, had been working for four months as a stewardess on the six-storey vessel.
The family also believes the yacht, which belongs to a Mexican mining mogul and billionaire Alberto Bailleres who had left well before the incident happened, was allowed to leave port before the crew had been fully interviewed and before the investigation was properly completed.
The Mayan Queen IV is now berthed in the main port of Mediterranean party island Ibiza. It made a beeline for the island after it was released to set sail by authorities on Sunday.
The statement expressed “trust” in Greek authorities investigating the death, however, the family also wants to press them to reveal the full details of their investigation.
The family lawyer has not yet received the ‘case file’ from the investigation, which may not be available for months.
