Quoirin was discovered to be missing from her family’s hotel room on the morning of August 4, the day after the London-based family arrived for a two-week vacation at a resort south of Kuala Lumpur.

The 15-year-old, who was born with the brain defect holoprosencephaly, traveled to Malaysia on an Irish passport with her parents and two siblings for a two-week vacation. Her mother Meabh is a native of Belfast, and her father Sebastien is a native of France.

Following her disappearance, hundreds of volunteers trawled the nearby rainforests in search of the "vulnerable" teen, and two separate GoFundMe pages were launched to assist the family, who was additionally receiving support from the Lucie Blackman Trust, based in the UK.

Nora's body was found on August 13 about a mile from the resort. Authorities believe that she was likely dead for 2-3 days before being located.

In a press conference on August 15, Negeri Sembilan state police chief Mohamad Mat Yusop said that the post-mortem examination on Nora found no evidence that she had been abducted or of any foul play.

"For the time being, there is no element of abduction or kidnapping,” he said.

"The cause of death was upper gastrointestinal bleeding due to duodenal ulcer, complicated with perforation ... it could be due to a lack of food for a long period of time and due to prolonged stress."

He added that Nora had bruises on her leg, but those were unlikely to have caused her death.
