Her remains were discovered this week.
Nóra Quoirin’s parents have said they are hoping for “more answers to our questions” following the teenager’s death.
The 15-year-old girl’s body was found 2km from the Malaysian resort where she had been staying with her parents and siblings.
A postmortem showed that she had died from prolonged hunger and stress.
In a statement issued through the Lucie Blackmore Trust, the Quoirin family said that they are still hoping for more answers in relation to Nóra’s death.
“The initial post-mortem results have given some information that help us to understand Nóra’s cause of death,” they said.
“But our beautiful innocent girl died in extremely complex circumstances and we are hoping that soon we will have more answers to our many questions.
“We are still struggling to understand the events of the last 10 days.”
The family went on to thank the Malaysian authorities for their support and cooperation with international governments as the investigation continues.
“We will be bringing Nora home where she will finally be laid to rest, close to her loving families in France and Ireland,” they said.
Nora’s remains were found on Tuesday by a volunteer. The Lucie Blackman Trust has confirmed that no reward was paid out as a result of the discovery.
The teenager’s parents said that they are “heartbroken” by the loss of their daughter.
“Nóra is at the heart of our family,” they said.
“She is the truest, most precious girl and we love her infinitely. The cruelty of her being taken away is unbearable. Our hearts are broken.
“We will always love our Nóra.”
