In terms of actual evidence of foul play, I believe there was none.
They believe she was found by a stream in a recumbent position i.e. had found water and subsequently fell asleep, probably in excruciating pain and perhaps slipped in to a coma.
The actual cause of death seems unusual for layman, as I obviously am, but apparently not unknown - "Based on Nora’s post-mortem results, state police chief Mohamad Mat Yusop revealed that the official cause of death was upper gastrointestinal bleeding due to duodenal ulcer complicated by perforation, meaning there was internal bleeding in the intestines due to an ulcer which was brought on by starvation. “The cause of death was due to ruptured intestines which could be because she had no food for a long period and also long-term stress,” Mohamad told reporters.
Perforation of a stomach ulcer can be life-threatening if left untreated. According to the Mayo Clinic, ulcers can be caused by a range of things, from H. pylori bacteria in the digestive tract to certain medications. Extreme stress is not a direct cause, but it can make an underlying ulcer worse"
There were no footprints around the body, although she may have followed the path of a shallow stream.
She had minor scratches on her lower legs, indicative of brushing against jungle flora with bare skin.
It is believed she was dead for 4 days before she was found, but I found it quite telling that members of a local hiking club actually eventually discovered her, which again indicates why she may have gone undiscovered.
It would be interesting to find out if this apparent search of that area happened within that 4 days, but surely that all came out in the wash during the inquest.
There must be grounds for the parents to push for a 2nd inquest conducted by the French or Irish government, if such a legal device exists and I'm sure they're exploring that possibility.
