BJ Ahyeong’s body was found dumped on the outskirts of the Cambodian capital Phnom Penh last week.
Ahyeong, who boasted a quarter of a million Instagram followers, was believed to be a popular DJ in her home country.
The couple accused of her murder have claimed that Ahyeong suffered seizures while receiving treatment at their beauty clinic, later abandoning her body, according to the BBC.
Though Cambodian police have refuted those claims, with Prosecutor Plang Sophal telling the AFP news agency that Lai Wenshao and Cai Huijuan had been charged with “murder accompanied by torture”.

Reports suggest that Ahyeong’s body was wrapped in a red cloth with the grisly discovery made by locals.
In South Korea, media have reported her real identity as 33-year-old Byun Ah-yeong.
Ahyeong announced in March she would be stepping away from her public persona to “live as a normal person”.
