According to media reports, Huser was found on Sunday morning by emergency services from the Saas Valley rescue station above Saas-Fee after she had been reported missing the day before. Apparently, she slipped while crossing a several-metre-long body of water below the middle station of the Alpin-Express and fell down a steep slope.

Huser is a well-known figure in Swiss endurance sport, having celebrated her first major successes in mountain biking. She was one of the dominant figures in the national and international marathon series and also won the European Championships at this distance. In 2004, she put an end to mountain biking by winning the Swiss Marathon Championships, only to reappear shortly afterwards at the top of the rankings in running and triathlon, and later in trail running in particular. She was one of the top runners in trail running until summer 2020, but ended her long and successful time as a top athlete in the fall. She was considered an exceptional athlete due to her versatility, but especially because of her exceptional endurance.She contracted the coronavirus in mid-November and was on the road to a full recovery at the time of the accident. Born in Toggenburg, she lived and worked in Sigriswil.
