A true crime fanatic who told police she killed a total stranger "out of curiosity" has been handed a life sentence by a South Korean court.

Police claimed 23-year-old Jung Yoo-Jung, who had a high psychopathy test score, was fascinated with crime shows and books. She became obsessed with the concept of trying out a murder.

In May, Jung met an English teacher via an app and murdered her in her home. The murder horrified the whole country of South Korea.

The prosecution had made a request for the death sentence, which is something that is generally reserved for the most heinous of crimes. The previous execution in the nation took place in 1997, while the most recent death sentence was issued in 2018, said Unilad.

Laying Out the Plan and Carrying Out the Crime

Jung is an unemployed individual who lives with her grandfather. According to BBC, she has spent months looking for victims and reportedly utilizing a tutoring app to identify potential targets.

She reached out to around 50 people, asking whether they taught classes out of their homes. She specifically sought out women.

The 26-year-old victim, who was located in Busan in the south-east of the country, was approached by Jung in May. Jung was pretending to be the mother of a high school student needing English lessons. Police have not released any further information about the victim.

Jung then showed up at the tutor's residence dressed in a school uniform she had acquired online, authorities said. As soon as the instructor allowed her in, she brutally assaulted the lady, stabbed her over a hundred times, and went on even after she was already dead.

She then took a cab to a park north of Busan and dumped some of the body parts there and the rest in the river. Jung was caught when the cab driver tipped off authorities about a passenger who had dropped a blood-soaked bag in the woods.

For months, Jung allegedly investigated internet methods of murder and corpse disposal, according to the police. However, she allegedly did not take any precautions to prevent being seen by CCTV cameras as she repeatedly entered and exited the tutor's house, leading authorities to conclude that she was careless.

Shocking Confession From Suspect

In handing down the sentence on Friday, November 24, a judge in Busan's District Court stated the murder "spread fear in society that one can become a victim for no reason" and "incited a general distrust" in the neighborhood.

Jung, who pleaded guilty in June, said she was experiencing hallucinations and other mental illnesses at the time of the murder in an attempt to justify a lighter sentence.

But the court did not buy her story since the crime had been well planned and executed, making her claim of mental and physical illness doubtful, as reported by BBC.

It was pointed out that her comments to the police had been inconsistent. Ultimately, she admitted that her fascination with murder had been sparked by television series about crime.
