The story of two Dutch girls, Kris Kremers and Lisanne Froon, who went hiking in Panama. I'm not sure why it seemed like a good idea for two girls to go hiking in a Panamanian jungle but that's what they did and never came out alive. The story just get more and more weird the more you read. Some people believe they were killed by wildlife but the details of the story seem to indicate they were abducted and killed.
Here is a pic of the girls.
These pics was taken just a couple hours before whatever happened.
I found a site with a pretty thorough breakdown of the events including the recovery of their bodies, weird photos that were taken, 911 calls that were made in the middle of the jungle, etc. The post at the following link is long but it gives many of the details associated with the case including finding one of the girls shoes, with the foot still inside.
Don't start reading it unless you want to get sucked into it until the end because the details are like something out of a movie. Its long but a good read. The photos above, which are just a few of the ones taken, look like the beginning of a Blair Witch movie.
