According to Le Dauphine, the alert was given on Thursday 6 October in the afternoon, by the family of the hiker worried about not hearing from him.
From Thursday evening and into the night, searches were made by the Chamonix high mountain gendarmerie platoon (PGHM).
They continued on Friday 7 October. In the morning around 10:30 a.m. in the Aiguilles Rouges sector, the gendarms aboard the civil security helicopter discovered the body of a 30 year old man, at the foot of the Cheserys cliffs.
According to the first elements communicated by the emergency services, the man was from the Paris region.
In the absence of witnesses to the tragedy, it is difficult to establish with certainty the scenario of this accident.
According to the hypotheses of the Chamonix PGHM, the man would have gotten lost on the descent from Lac Blanc and Lac des Cheserys. This route error could explain his fall at the foot of the cliffs.
