Usually lost hikers start drinking river water.
They started their hiking trip with minimal food and water and must have suffered great thirst and hunger a few days in. Personally I think the girls simply but tragically died from exhaustion, mainly dehydration. I live on the land - kinda off-grid - and am deeply interested in all kinds of human survival experiences and have some experience with the realities of being in the wild. I believe they show them on their way up towards the Mirador at the Continental Divide. For anyone fascinated like me with the disappearance of the two Dutch girls Kris Kremers (21) and Lisanne Froon (22) near Boquéte, Panama: the following Spanish video features some new photos from Kris and Lisanne on April 1, 2014.
