According to the source, investigators said Yoo-jung posed as a mother on a tutoring app looking for someone to teach her daughter English.

She found the victim after contacting 54 people – mostly women – via the app. She arrived at the woman's home disguised as a young student and wearing a school uniform, the news agency reports.

“Jung is small and since she is wearing the uniform, the victim probably thought she was a middle school student,” the police spokesman said. The Chosun Ilbo.

After entering the victim's apartment, Yoo-jung stabbed her multiple times. She then went to a supermarket where she bought trash cans and bleach before returning to the apartment and dismembering her, the police spokesman added.

According to BBC, Yoo-jung then took a taxi to dispose of some of the body parts in the forest, and the driver then alerted the police to her suspicious behavior. Parts of the body were discovered in the forest, while other body parts were found in Yoo-jung's house. The Chosun Ilbo reports.

According to BBC reports, police also said her browser history showed that she had been searching for ways to kill and dispose of a body in the months before the murder.

She was arrested and convicted of murder, desecration of corpses and disposal of bodies, Korea JoongAng Daily reports. In addition to her sentence, she must wear a tracking device for 30 years.

On Friday, the Busan District Court judge said Yoo-jung committed the murder “even though he did not know her beforehand for her own perverse reasons,” according to the outlet.

They also said the crime had fuelled “a general sense of mistrust” in South Korean society, the BBC reports.

According to the BBC, the victim, whose identity was never made public, was 26 years old.
