NORA QUOIRIN died of intestinal rupture as a result of starvation and stress, Malaysian police have confirmed.
According to the local authorities, the 15-year-old died two or three days ago.
The results of the post-mortem found no indications of sexual assault while there is no suspicion of foul play “so far”.
Nora, who was travelling with her parents and two siblings on an Irish passport, disappeared from her hotel room at the resort of Dusan on Sunday August 4.
The teenager was described as “vulnerable” by her parents on account of the fact she was born with the brain defect holoprosencephaly.
Her body was found following a 10-day search, beside a small stream roughly 1.6 miles from the resort.
“Nora is at the heart of our family. She is the truest, most precious girl and we love her infinitely,” her family said in a statement.
“The cruelty of her being taken away is unbearable. Our hearts are broken.
“We will always love our Nora.”
“We would like to thank all the people that have been searching for Nora and trying their best to find her,” they added.
“We thank the local people here and those far and wide for their prayers and support at this time.
“Nora has brought people together, especially from France, Ireland, Britain and Malaysia, united in their love and support for her and her family.
“To all our friends and family at home, we can’t thank you enough for all your love.”
