The inquiry begins today.
Malaysian authorities have opened an inquest into Nóra Quoirin's death.
The 15-year-old girl died last year near the Dusun Rainforest resort where she had been holidaying with her parents and siblings.
An autopsy showed she died from prolonged hunger and stress. At the time, Malaysian police closed the case and deemed "no further action" was to be taken.
Nóra's parents, Sebastien and Meabh, called for an inquest into their daughter's death stating that she would not have wandered off from the resort.
RTÉ News reports that the inquest, which begins today, will consider whether "there is any person who was the primary concern on the cause of death."
Coroner Maimoonah Aid will look at how, where, and when the teenager died. Over 60 witnesses, including police and the hikers who discovered Nóra's body, will appear at the inquest.
Sebastien and Meabh will speak via video call due to Covid-19 travel restrictions.
Following their daughter's passing last year, the couple said they were
looking for "more answers."
"The initial post-mortem results have given some information that help us to understand Nóra's cause of death," they said in a statement.
"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 have the support of Irish, French, and British governments.
