Former world junior pairs figure skating champion Ekaterina Alexandrovskaya mysteriously died on Friday, marking the second death to hit the Australian Olympic community this month.

Alexandrovskaya, 20, died in her native Russia on Friday, although the details of her passing were not immediately known, the International Skating Union confirmed.

“It is with profound sadness that the ISU learned of the sudden and unexpected passing of pair skater Ekaterina Alexandrovskaya (AUS) in Moscow,” a statement posted to their website read.

“The ISU is shocked by the news of Ekaterina's passing,” ISU President Jan Dijkema said in a statement. “She was a talented pair skater and the Figure Skating community will miss her. We offer our deepest sympathies to her family, friends and teammates and mourn this tragic loss”

Alexandrovskaya was born in Russia but obtained her Australian citizenship in 2016 and represented the country at the 2018 Pyeongchang Olympics with partner Harley Windsor.

The duo took home the world junior title in 2017 but Alexandrovskaya was forced to retire this past February after sustaining several injuries.

“Words can not describe how I feel right now, I am devastated and sick to my core about the sad and sudden passing of Katia,” Windsor wrote in an Instagram post. “The amount we had achieved during our partnership is something I can never forget and will always hold close to my heart. This news is something you can never prepare for. Rest In Peace Katia.”

Alexandrovskaya’s death comes just weeks after two-time snowboard world champion Alex Pullin drowned while spearfishing off Australia’s Gold Coast. The 2014 Winter Olympian was discovered by a snorkeler near an artificial reef earlier this month.

“Katia’s death is another blow to our winter sports community who are still reeling from our loss of ‘Chumpy' Pullin," Ian Chesterman, chef de mission for the Australian team in Pyeongchang, said Friday.

Chesterman said that Alexandrovskaya appeared to struggle after the 2018 Winter Olympics, although he did not say with what.
