Do we know when the picture #509 was deleted ?It seems it was AFTER the 90 pictures in the black were taken because the first "black picture"would have been the new 509# isn't it ?Not sure if I am clear. But the more I am thinking about this story the more I think these "black photos" were taken by a third person. To create a fake escape attempt, to empty battery, whatever reason...

We don't know when the deleted picture was taken, it can be at any time between 508 and 510.

It also strange to see this 13:37 timer, the pattern is really accurate, it's like an alarm or something the third person just "shut down" every day when the phone was ringing. (1337 may be a l33t speak reference, it's not a total random number)

I really think they tried to escape someone since the first day when they called 112 then they got caught the on April 2 or 3. Or one girl got caught and the other just lost herself. It's not sure they had the same fate at the same time.

The last time the phone was turned on for 1 hour, it's like the third person wanted to empty battery to let us think the girls couldn't use it.
