For days, Luis Stitzinger was considered missing. Now, according to consistent media reports, his body has been found on the world's third-highest mountain.

Apparently, the extreme athlete had been traveling without artificial oxygen. The body of the 54-year-old was found at an altitude of 8400 meters and would be brought down by five Sherpas, Mingma Sherpa, the head of the expedition company Seven Summit Treks, told The Himalayan Times. The experienced mountain and ski guide has been missing since last Thursday.
