Authorities believe that food poisoning is the likely cause of the two deaths at Phi Phi islands over the weekend. The autopsy reports will not be ready for another two weeks. The fiancée of the American woman suspect she was poisoned from chemicals from a nearby water treatment plant.

According to sources we spoke to in Phuket and Krabi on Thursday this is not the case.

- There are no traces of cyanide. It will take at least two weeks before we have the results. This may be a misunderstanding by the Norwegian newspaper, said a police source in Krabi today to Andaman Times.

The fiancée of Jill Sheree St. Onge (27) believe she was poisoned from chemicals of a nearby water treatment plant.

- I found out later that there is a water treatment plant right behind the guesthouse. I feel that Jill was poisoned by a chemical from that plant. She spent about 5 more hours in the room than I did. She was just breathing in the fumes for so long. The only reason I did not get deathly ill, is that I kept getting these short breaks from the air in the room, writes Ryan Kells on a family blog.
