Like I said, if she was suffering from internal bleeding from ruptured ulcers she would have been in agony, food would have been the last thing on her mind so I very much doubt she would have eaten soil!!!
Ruptured ulcers can kill you quite quickly without medical attention and would have added to any confusion she was already suffering.
I think some lessons may be not to go missing in a third world country, don't die in a third world country, don't rely on science in a third world country, don't rely on the authorities in a third world country.
It's all very tragic but wrong place and wrong time.
Such a tragic story and don't want to make lite of it... personally I think that the Malaysian police are talking Bu'*** I don't believe she wandered off on her own, to see a waterfall or cool down. I hate to think it but believe sadly something sinister happened to her... Taking advantage of her learning disabilities.
