Sinead McNamara, a 20-year-old Instagram model, had called her mother in tears just days before she was found tangled in the rope at the back of a billionaire's superyacht.
She was reportedly unconscious and later died at an Athens hospital—but her family now wants answers about what caused the young model's death, according to the family's lawyer, Charalampos Triantafyllopoulos.
"The family finds it crucial to thoroughly investigate both the conditions of death and the events and incidents that preceded this event in order to reveal the full truth and learn what actually happened and led their 20-year-old daughter to death," the lawyer said, according to The Sydney Morning Herald.
Greek authorities are still investigating the circumstances behind the death; however, media reports have suggested the death may be a suicide.
Greek coroner Ilias Bogiokas reportedly told the Athens Macedonian News Agency that McNamara died from hanging and did not have any other injuries on her body at the time of the death, according to news and entertainment website news.com.au.
However, in an interview with The Guardian he said he had "doubts and questions" about the death.
“The answer lies with the toxicological and histological tests,” he 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.”
Her family's attorney said at the time of her death McNamara had been just days from leaving the yacht to return to her family.
"The parents also state that Sinead was not having any problems, she often communicated with her family and she was happy," the attorney's statement said according to the Morning Herald.
She had been spending the summer working as a member of the staff on the Mayan Queen IV, a yacht owned by Mexican mining billionaire Alberto Bailleres. Bailleres and his family were not on the boat at the time of the incident last month.
Shortly before her death, the attorney said, she had called her mom and brother crying as she recounted an incident that took place on the yacht with another crew member.
The family now wants answers about the events leading up to McNamara's death and has also questioned why it took so long for McNamara to be transferred to a hospital after she was discovered.
"She had been unconscious for several hours in a comatose condition and every minute was critical to her life," Triantafyllopoulos said.
The superyacht was released on Sunday by Greek authorities after investigators reviewed CCTV footage and interviewed crew members.
The official cause of death is not expected to be released until the coroner's report is finalized.
