A 23-year-old true crime fanatic was arrested in the South Korean city of Busan on Wednesday in connection with the killing and dismembering of a woman, according to law enforcement authorities.

Police said they believe the killing was done "out of curiosity," driven by the suspect's desire to experience what murder was like firsthand, South Korea's oldest newspaper The Chosun Ilbo reported.

The newspaper said that Jung Yoo-jung confessed to the killing and was indicted for murder on Friday.

Initially, Jung claimed to have killed the victim during an argument but later retracted the statement when presented with contradictory evidence by investigators, per The Chosun Ilbo.

A police spokesperson said they suspect the murder was premeditated and was driven by Jung's desire to kill someone for real after she "became obsessed with murder from TV programs and books."

An investigation of Jung's phone revealed three months' worth of search history on how to hide a corpse, according to the newspaper.

The investigation also revealed that Jung had watched true crime TV shows and borrowed crime books from a library, The Chosun Ilbo reported.

Police said Jung searched for a victim online, eventually finding one through an app that connects parents with private tutors, per the newspaper.

Two days before the killing, Jung contacted the victim, posing as the mother of a ninth-grader, to arrange a visit to the victim's home, the newspaper said.

Police told The Chosun Ilbo that on the day of the crime, Jung went to the home disguised as a student wearing a school uniform she had purchased online. Once inside the property, police allege that she fatally stabbed the victim, per the newspaper.

Police then say that Jung dismembered the body, placing some of the corpse in a suitcase that she dumped in a wooded area by a river, and leaving other parts of the corpse in her own home, the newspaper reported.

Jung kept the victim's cell phone, ID card, and wallet in a bid to try to "commit a perfect crime," the spokesperson said, per The Chosun Ilbo.

However, the taxi driver who took her to the wooded area alerted the police, the newspaper said. Police then found blood-stained clothes in her bags.

"Jung was a loner and a recluse who has been unemployed since graduating from high school five years ago," police said, per the newspaper.

The police spokesperson told The Chosun Ilbo that Jung said she feels remorse for what she did.
