"This is not the first disappearance in the sector of the Pyrenees, rescuers estimate that it will take three to five years to find the body ...

As much in the glaciers of the Alps, people who disappear are at the bottom of the glacier and reappear when the glacier goes down, it can last twenty to thirty years, as much in the Pyrenees, we end up finding the body within five years because there is someone who happened to pass by there."
