Nora Quoirin’s grandfather has said there are “many dark areas that need to be cleared up” over the teenager’s death in Malaysia.
The 15-year-old was found near a jungle stream on Tuesday, 10 days after she went missing on a family holiday.
An initial post-mortem examination found she died from internal bleeding, thought to be caused by prolonged hunger and stress, but Sylvain Quoirin said there was no way Nora would have ventured out alone in the middle of the night.
He told The Irish Times: “Can you imagine her walking 2.5km, naked and barefoot, over rocks, in the middle of the night? For me, that’s absurd.”
Mr Quoirin said Nora – who had learning difficulties – was extremely sensitive and shy and “clung to her parents and sister”.
“If she went out alone by mistake, she would have banged on the door and screamed to be let back in,” he said.
Nora’s family initially feared she had been abducted, but so far police say they have found no signs of an attack or sexual assault.
Her body was eventually found near a stream not far from the jungle resort where the family were staying – despite a major search operation going on for a week-and-a-half.
Nora’s grandfather told the newspaper search members would not have missed her body: “She wasn’t there yet. Someone put her there, to get rid of her.”
A lawyer for the girl’s parents – who are French and Irish and have lived in London for 20 years – has also said it is too early to rule out criminality.
“We have to be very cautious about the first result of the autopsy because we have not the definite, complete conclusion,” said Charles Morel.
He told Ireland’s RTE Radio 1 that “for the time being” the family were happy with Malaysian authorities, but were still waiting for toxicology and DNA analysis from the post-mortem examination.
Mr Morel said – like Nora’s grandfather – her parents still cannot understand how Nora would venture off by herself in the night – especially in such an unfamiliar place.
“We cannot exclude the criminal hypothesis… we have to wait for the complete result of the autopsy,” said the lawyer.
He added: “[The family] are just now concerned about the truth, because they owe that to Nora.”
