Figure skating star Ekaterina Alexandrovskaya dies aged 20 in suspected suicide
Details of the tragedy are still emerging, although Russian outlet TASS reports that Alexandrovskaya is believed to have committed suicide by jumping from an apartment window.
According to a source cited by the agency, the former skate star left a note reading "I love (you)."
In the wake of the incident, Alexandrovskaya's mother was reportedly hospitalized and is being treated for shock.
Moscow-born pairs skater Alexandrovskaya switched allegiances in 2016 after teaming up with Australian skater Harley Windsor, twice winning the Australian national title and also claiming gold at the World Junior Championships in Taipei in 2017.
The pair also scooped the top prize at the Junior Grand Prix Final in Nagoya the same year, becoming the first Australian champions in the event's history.
Alexandrovskaya and Windsor also competed at senior level, finishing 18th at the Winter Olympics in PyeongChang in 2018.
The pair were forced to withdraw from a series of events during 2019, later splitting when health issues forced Alexandrovskaya to retire.
After the news of Alexandrovskaya's death was reported, Windsor was among those to pay tribute, writing that he was "devastated."
"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," the Australian wrote on Instagram.
"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."Also on rt.com 'Devastated to my core': Former partner pays tribute to Russian-born skate star Alexandrovskaya after death age 20
