Nora Anne’s case drew world attention due to the parallels with the Madeline McCann case in Portugal.
The remains of the 15-year-old, who is of Franco-Irish parentage, were found on Tuesday following a massive search and rescue operation mounted by Malaysian authorities after she was reported missing from a holiday villa at an eco-tourism resort near here on Aug 4.
The post-mortem findings revealed that Nora Anne, a special needs teenager, died of internal bleeding likely due to starvation and stress.
The Quoirin family had checked in at the resort on the verge of the Malaysian Main Range rain forest on Aug 3 for a two-week holiday.
They sounded the alarm after discovering that Nora Anne had vanished from the accommodation the following morning, a window in her room ajar.
Madeleine Beth McCann disappeared on the evening of May 3, 2007 from her bed in a holiday apartment in Praia da Luz, a resort in the Algarve region of Portugal. She was three years old then.
Her whereabouts till today remains unknown.
