And if you spend 2-3 days sh***ing your guts out, things become life-threatening very fast without any foul play or accidents. But the following vomiting and diarrhea have the effect that the bodies loses even more water - no matter how much river water you drink.
Even if you have some experience and know that (to the foreign stomach) harmful microbes in the water can cause massive sickness, things look very differently to you when the dehydration becomes to great you would kill for a sip of water. 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.
