The 25 years old Polish climber, Krystian Madeja, was part of an expedition team which included five Polish and Russian experienced mountaineers, including famous Russian climber, Denis Urubko.
The mountaineers were climbing Mont-Blanc on the French-Italian border on the 24th of February 2019.
Krystian Madeja and his team started their ascent from Chamonix.
When he reached the so-called "Couloir of Death" of Mont-Blanc, Krystian Madeja recorded a live video on Facebook.
His words from the Facebook video were: "Best regards, and we wish you all a nice day! Hey mum! She is also watching the live-streaming. Look, mum, beautiful isn't it? There is nothing to worry about, I'll be home soon. This is the so-called Couloir of Death."
Shortly after the video was recorded, the 25 years old Polish mountaineer fell into a 400 metres ( 1,312-foot) abyss and died immediately at the 2,200 meters ( 7,218ft) altitude.
The PGHM of Chamonix ruled that the accident was caused by a "lack of vigilance", as Krystian was not connected with a rope to the other members of the team at the time of his death.
According to the DailyMail, Mr Polissen, a spokesperson for the PGHM, declared: "The Polish climber fell down a steep snow slope after having poorly set up a climbing crampon that came loose and he slipped."
Krystian Madeja died on impact. The PGHM was there 15 minutes later to evacuate the body.
The heartbreaking video has been viewed for more than 12,000 times on Facebook.
