On Saturday, the Quoirin family arrived in Malaysia for a family holiday.
Mum, Meabh, and dad, Sebastien, an Irish-French couple from London, and their three children, travelled to the Dusun eco-resort, 63 kilometres south of Kuala Lumpur.
They had planned to stay for two weeks.
But by Sunday, their 15-year-old daughter, Nora, had vanished.
The British teenager, who has learning and developmental disabilities, disappeared from her upstairs bedroom in the middle of the night.

According to police she was sharing the bedroom with her two siblings, but no one saw Nora leave the room or walk out of the resort.
While it was initially ruled that there was no foul play involved, police are now investigating the case as a potential abduction.
“Although we classified this case as a missing person but we are not ruling out any possibility… the scale of investigation and the search and rescue is very big for a small place here,” Negeri Sembilan deputy police chief Che Zakaria Othman told a news conference this week.
In a statement released on Tuesday, Nora’s family said they believed she had met with foul play.
“Nora’s family believe she has been abducted,” the statement read. “We are especially worried because Nora has learning and developmental disabilities, and is not like other 15-year-olds.
“She looks younger, she is not capable of taking care of herself, and she won’t understand what is going on.”
Members of the Senoi Praq, a special police team comprising indigenous tribes famed for their forest tracking skills, combed the dense forest surrounding the resort on Thursday. As they searched they called out Nora’s name, and played recordings of Nora’s mum’s voice through loudspeakers, but they found no trace of the teenager.
Her case is now being compared to that of Madeleine McCann, the British toddler who disappeared from a holiday resort in Praia da Luz, Portugal, in May 2007.
Investigators in that case believe Madeleine was abducted and carried out of the holiday villa through an open window in her bedroom.
In Nora’s case, investigators found an open window in the downstairs living area. They dusted for fingerprints and found “unknown prints” on and around the window.
