"We are profoundly sorry. We did not have an indication that the checks had not been done," Crans-Montana Mayor Nicolas Feraud told reporters on the absence of fire checks between 2020 and 2025. The mayor added that the sound-proof foam used in the bar Le Constellation was considered acceptable at the time. Prosecutors have said that the fire that spread rapidly in the early hours of January 1 was likely caused by sparkling candles igniting the ceiling of the bar's basement.
