Kamilla Belyatskaya, 24, was reportedly doing yoga on a rock in Thailand, when a wave swept her into the ocean. In one of her previous posts on social media, she said the spot was the "best thing" she had ever seen in her life.
The incident happened just days before the 24-year-old was supposed to get married to her partner of five years.
Belyatskaya's fiancé says he found out she was missing from social media. "I was still praying for a miracle, that my fiancé would be found alive. I'm devastated, I'm heartbroken. We were going to get married in a few days," he said.
Rescue teams unsuccessfully tried to save Belyatskaya. Her body was found days later at a nearby hotel.
