Olympic figure skater Ekaterina Alexandrovskaya died in Moscow Friday, and new details have been revealed about her death. The 20-year-old fell out of a sixth-floor window from her apartment building after she left a note that read “Lyublyu”—“I Love” in English—according to Russian media.

The preliminary cause of Alexandrovskaya’s death is suicide, according to TASS, a Russian News Agency.

Alexandrovskaya represented Australia at the 2018 Olympic Winter Games in PyeongChang, South Korea. She quit figure skating in January, according to her coach Andrei Khekalo, after she missed a training session in January and was diagnosed with epilepsy.

Alexandrovskaya skated in pairs with Harley Windsor at the 2018 Olympics, where they placed 18th in the short program. A year prior, the duo won gold at the 2017 World Junior Championships.

“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 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.”

In February, Windsor announced that the pair would no longer be skating together because of Alexandrovskaya’s health concerns.
