Research
Jung had spent months looking for prospective victims through an app that connects parents to tutors, and contacted more than 50 people — mostly women — before finding one who lived alone and offered lessons at home. -
The murder continued
She then dismembered the woman's body and took a taxi ride to dump some of the remains in remote parkland near a river. She was arrested after the taxi driver tipped off police about a customer who had dumped a blood-soaked suitcase in the woods. -
The murder
On the phone, 23-year-old Jung Yoo-jung posed as the mother of a 9th grader who needed English lessons and went to the unsuspecting woman’s address and stabbed her to death more than 100 times in a frenzied attack, delivering blows even after the victim had died, officials said. Jung left the slain tutor’s home to buy trash bags and bleach before returning to dismember the body, including cutting off her fingers in a bid to make her more difficult to identify her by her fingerprints. -

Court
Jung, who confessed to the crime, pleaded for a more lenient sentence, saying she had suffered hallucinations and other mental disorders at the time. But the court rejected her argument as the crime had been"carefully planned and carried out, and it is difficult to accept her claim of mental and physical disorder".
Initially Jung said she had only moved the body after someone else killed the woman, later claimed that the killing had occurred as a result of an argument. -
Convicted
Jung was convicted of murder, desecration and abandonment of a corpse, and was sentenced to life in prison
