The body of Nora Anne Quoirin, 15, was discovered unclothed after a hunt through the rainforest following her disappearance from the Dusun resort at Pantai, near here, in 2019.
Police insisted there was no foul play and an autopsy found that she probably starved and died of internal bleeding after days in the jungle.
But her parents think she was abducted, saying the teen would never have climbed out of the window of the chalet where they were staying in the dead of night, as police believe.
However, following an inquest, coroner Maimoonah Aid said there was no sign the teen had been murdered or sexually assaulted, and ruled she died by “misadventure”.
“After hearing all the relevant evidence, I rule that there was no one involved in the death of Nora Anne,” she said.
“It is more probable than not that she died by misadventure.”
The teen likely left the family accommodation “on her own and subsequently got lost in the abandoned palm oil plantation”, she said.
The inquest, which ran from late August to December, heard from over 40 witnesses and was streamed online because of the Covid-19 pandemic.
Massive search
During proceedings, police reiterated their view the teen had wandered off alone from the resort in August 2019, a day after checking in for a holiday with her London-based family.
They defended their approach, insisting a thorough search was conducted.
But her parents, who testified via video link from Britain, painted a different picture, strongly criticising authorities for their response to their daughter’s disappearance.
Her mother Meabh said police were slow to launch a full-scale search and did not take her concerns about potential criminal involvement seriously.
Her father Sebastien also said he heard mysterious “muffled noises” coming from the chalet the night of the schoolgirl’s disappearance, fuelling the family’s belief she was snatched.
The search lasted 10 days and expanded to include hundreds of rescuers, helicopters and sniffer dogs, before Nora Anne’s body was found in a ravine not far from the resort.
The 5ha site is next to a patch of thick jungle and in the foothills of a mountain range.
Nora Anne had a condition known as holoprosencephaly, where the brain fails to develop normally. She had limited verbal communication and could only write a few words.
She attended a school for young people with learning difficulties.
