>> he said i want to go back up because i have never been turned away from an everest summit before. it would be like if lebron james came and asked you to play horse, would you say no? i was like sure, i'm going to do it.
>> narrator: it seems as if sandra leduc was also having a change of heart .
>> it seemed so very wrong. i turned to my team leader and said, i think i want to go back up.

>> i summited at 3:30 in the morning.
>> so no picture?
>> i couldn't take a picture. but i had video.
>> 8850 meters.
>> narrator: the amazing speed with which he and his sherpa summited mt. everest left them with plenty of time to see a spectacular sunrise.
>> this is it, the top of the world .
>> narrator: at about 6:00 a.m ., sandra leduc and the others reached the summit too.
>> i got really emotional. this is the moment i had been dreaming of for 12 years.
>> i'm tired but i'm hanging in there.
>> narrator: they were still feeling the elation of having summited mt. everest as they left. but just a few hundred yards down the mountain, they came upon a body still clipped to the rope line. red suit , yellow boots, it was shriya shah.
>> when i went up and i saw the canadian flag , i felt sick, and when i came down, then i wanted to cry.
>> we both passed her and stopped for a moment and paid our respects and said, the mountain makes the decisions and then i continued on.
>> narrator: it turns out that shriya did not die alone. back on the night of may 19 , not long after her sherpas left her. another sherpa passed by on his way up. he says shriya was still alive, but barely. he says he gave her a sip of oxygen from his tank and was with her when she took her final breath. then he took this picture to document the location of her body. shriya shah was one of six people who died on mt. everest that day. dozens more had to be rescued by helicopter. in all in 2012 , six climbers died. the deadliest season of all on mt. everest . but ironically it was one of the most profitable years for the governments who charge fee force the climb. shriya 's husband, bruce klorfine made arrangements to have his wife's body brought down from the summit.
>> narrator: shriya shah was cremated in her birthplace of kathmandu. according to tradition, her husband lit the funeral fire. sandra leduc said shriya shah's story should be a warning.
>> unfortunately, there are a certain number of people who do try every year who don't have the experience. but that's partly because of the public perception that it's just a walk.
>> narrator: the fact remains, mt. everest is not only the world's highest mountain , but also the most lethal. that danger is one big reason why experienced climbers and thrillseekers alive will be hoping to cheat death and live to tell the tale.
>> every year there will be a slow brood letting of people who shouldn't be there
