The body of a 15-year-old Irish-French girl, found in a deep canyon in Malaysia after 10 days of research, has died of gastrointestinal bleeding from severe hunger.
"The cause of the death of Nora Annie Quirin is the gastrointestinal bleeding caused by a duodenal ulcer that has become a perforation," authorities told reporters at a news conference.
The 12-hour examination showed the girl died two to three days before her body was found naked in a deep canyon 2.5 km from her last appearance. The examination found no evidence of the girl being raped.
The authorities also said that "so far" there was no indication that the girl had been kidnapped.
The Guerin family reported on August 4 that they had disappeared from their hotel in the Dawson resort in Nigeria's Sembilan state, 80 km (50 miles) from the Malaysian capital Kuala Lumpur.
Her body was found on Tuesday afternoon and taken to a hospital by helicopter to identify her.
The discovery ended a search involving indigenous tribal elements, local volunteers, hundreds of firefighters and police from Malaysia, Ireland, Britain and France.
Quirin's disappearance was puzzling for investigators, who initially struggled to find concrete evidence indicating their possible whereabouts.
The search was difficult because the girl was suffering from a "brain fusion", a disorder that causes learning and developmental difficulties.
Quirin lived with her family in London, but had dual Irish and French citizenship.
