Sorry to keep banging on about it, but I’ve been doing more reading on the Panama case and I’m convinced they were not wandering around the jungle during those eight days between photos. Kris’ hair is clean and dry, and while a bit mussed definitely doesn’t look like someone who’s been lost in a jungle for many days. The backpacks and contents were all clean and dry and in immaculate condition, including an iPhone - I’ve had iPhones stop working because of the tiniest bit of water damage, so that seems unlikely. And the woman who found the backpack said it wasn’t there the day before. The iPhone still had battery power, when the iPhone 5 was notorious for poor battery life and even if it’d been switched off the battery still would have drained.
They you have things like the tour guide having a key to the girls’ bedroom, and he and Eileen (who worked at the language school) spending time in their bedroom after they went missing. He could easily have brought their camera with him and deleted the missing photo then. The tour guide allegedly has a bad history of sexually harassing and threatening young female tourists. And there’s the photo of the girls swimming in with three young men, taken in the same location.
Then there’s the dog the host family claims was with them, who they claim arrived home alone (this is what sparked them to call the authorities). But the dog doesn’t appear in any of their pictures and none of the people who saw them remember a dog. The girls were huge animal lovers and took a million photos. They loved taking Instagram-style pics. But they didn’t take one photo of a gorgeous dog with those stunning backdrops? Didn’t accidentally get even a bit of the dog in the background of the photos they took of each other?
I believe they probably spent those 8 days staying somewhere else, possibly at the tour guide’s son’s farm, possibly with the young guys. This may have been voluntary or not. Possibly they got scared of something/someone and tried to call 911, and someone they’d met offered them shelter and they later found themselves unable to leave. There could even be two separate third parties, perhaps colluding, perhaps not. I don’t see how there can not be third party involvement.
