The husband of two-time Olympic Gold medalist Justyna Kowalczyk has died following an avalanche in the Swiss Alps, officials confirmed this week. He was 38. 

Kacper Tekieli, who married Kowalczyk in 2020 and with whom he shares a 20-month-old son, was killed in an avalanche, the Polish Mountaineering Support Foundation said. 

"He was the most beautiful Person in the world," Kowalczyk wrote in a Facebook post on Thursday.

Kowalczyk is a Polish cross-country skiing medalist. She won bronze in the 30km freestyle in 2006, Poland’s first Olympic medal in cross-country skiing. 

She won gold in the same event at the next Olympics in 2010 and then her second gold in the 10km individual in Sochi in 2014.
