Nora Quoirin died from internal bleeding thought to be caused by prolonged hunger and stress, Malaysian police have said.

Authorities on Thursday said there was currently no evidence of kidnapping in the London teenager's disappearance, and said the post-mortem did not find any sign she had been sexually abused.

Investigators said she had been dead for up to three days when the body was found.

The remains of the 15-year-old, who was born with the brain defect holoprosencephaly and was described by her family as "vulnerable", were found on Tuesday near a jungle stream 10 days after she went missing from a rainforest resort in Seremban.

'We know you are searching night and day for Nora'

She had been on holiday at the eco resort in Malaysia with her parents and two siblings.


Nora's devastated family said their "hearts are broken" and paid tribute to her as "the truest, most precious girl".

They said she had "truly touched the world" after her disappearance sparked a huge search operation and well-wishes across the globe.

Nora went missing on 4 August, when her father raised the alarm when he went into the room she shared with her two siblings at 8am and discovered she was gone.

Her family said they believed she had been abducted, but police in Malaysia treated it as a missing persons case.

Her parents, French-Irish couple Sebastien and Meabh Quoirin, explained that Nora read like a young child, could not write more than a few words, and was unable to do maths, making money impossible to manage.

They said she was unable to make or receive phone calls independently and that it was unusual for her to go wandering off.

Over the course of the search, nearly 350 people were involved in looking for the teenager, many of them volunteers or hikers.

Police investigated footprints in the jungle and fingerprints left on a window in the downstairs hall of the property they were staying in.

A recording of her mother was also played out over loud speakers by members of the search and rescue team in the hope of tracking her down.

Her body was eventually found, unclothed, on Tuesday about 1.6 miles from where she had been staying.

Rescue workers alerted authorities to the discovery and the area was sealed off. Her body had to be winched by helicopter to be taken to hospital, as it was in a hard to reach place.

Her family confirmed the body was Nora's hours later.

The full cause of death was given as "upper gastrointestinal bleeding due to the internal ulcer complicated with a perforation" and "bleeding internal in her intestine".

There were some bruises on her leg but these were not likely to have led to her death, police said.

An anonymous Belfast businessman put up £10,000 as a reward for information leading to Nora's whereabouts and a fundraising page raised nearly £100,000 to help cover unexpected travel costs.

The family has been working with The Lucie Blackman Trust (LBT), a charity which helps people with relatives in crisis abroad.

'Nora darling, mummy's here'

Matthew Searle, the charity's chief executive, was in personal contact with the family and previously told Sky News the process of repatriation would depend on whether extensive tests were carried out on Nora's body.

While samples from Nora's body have been sent to the police chemistry department for further testing, Negeri Sembilan police chief Mohamad Mat Yusop has said the family can take her body at any time.

A book of condolence was opened on Wednesday in the City Hall in Belfast, where Mrs Quoirin is from, and the Lord Mayor of Belfast was the first to sign it.

John Finucane said the teenager's death was "heartbreaking" and praised the "clear and positive" show of solidarity from the people of Belfast.

A special service was held earlier in the week at the south Belfast church where Nora was baptised and where her grandparents are parishioners.

'There was a great deal of love for Nora'

The south London church where Nora was a parishioner has also been holding regular vigils for her.

Nora's family attend St Bede's in South London, and the parish priest Father Marcus Holden told Sky News there was a "great deal of love for Nora".

He said she was a shy girl but an integral member of the community, who loved her family and was devout and prayerful.
