The other similarities to the DPI, is the mass of social media adding speculation and muddling the water to get hits.
However ,there are a lot of oddities. Although its difficult to know the original sources of any of the reported data.
The only logic I can apply to the series of night time photos with the flash , is that maybe ....and I say maybe as the only small logical explanation that I can think of, was that they were trying to light a fire.
Given what can be seen in the photos , the head of hair, possible outlines of fingers, the upward facing framed shots towards the sky, it makes me think that they possibly had the camera on the ground and were potentially using the flash to try and ignite the small bits of paper that they had torn up from the tourist resort map that they had.
The map is seen in an earlier photo at a restaurant with the various symbols , these graphics are also seen in the small bits of paper that show up in the night time photos. Also we see what looks like the bottom of the pringles tin.
I don't think the flash would be hot enough to actually start a fire but they do get hot to the touch and if the girls had thought that it might work , then it gives us an explanation to the strange nature of the photos , the frequency of shots and what is being seen at that moment in time.
I cannot put any other logic to those photos, not from outsiders being involved , nothing. It is truly odd.
It is the possibility of a survival situation . Like wise we have the picture of the tree branch with the two plastic carrier bags attached. To me , this lends itself to being used to keep the phones dry and above their heads as they cross or use a river to try and get to safety.
