When you finish this video, you're going to Google two words. In 2014, two Dutch college students were staying in Panama when they decided to take their host family's dog out for a walk. The dog returned, but the girls didn't. After 10 weeks without any leads, a local woman turned in a blue backpack that contained the girls' cell phones and their camera. Using their call log, they were able to determine that the girls would attempt to reach emergency services 77 times, all unsuccessful, starting just hours into their trip. It was also determined that five days after those 77 calls, somebody tried unsuccessful several times to unlock the girls' phones. But the most distressing thing is what was found on the camera. The first set was taken on the day they left, and they were totally normal. The second set was taken in the middle of the night over a week after they had left, and it showed all their belongings neatly laid out on a rock, and it showed one of the girls who appeared to be hurt. They found their remains spread out around the area where the backpack was found, and some of their bones appeared to have been bleached.

There is still no official cause of death or explanation as to what happened.
