Jeong Yoo-jeong Searches 'Murder of a Lineal Ascendant' After Victim's Horrific Mutilation

'If I don't kill, anger won't subside' note by Jeong Yujeong
Professor Lee Sujeong "The object might be the father"

Jeong Yoo-jeong, who murdered a woman in her 20s she met through a tutoring app and disposed of the body, showed brutality by stabbing the victim hundreds of times during the crime. Having lived alone with her grandfather, Jeong Yoo-jeong was revealed to have harbored significant anger towards her family, to the extent of searching for 'filicide' online.

Jeong Yoo-jeong used the tutoring app to look for a target who lived alone, was female, and could have tutoring sessions at home. The direction of her suppressed anger was aimed at the victim, whom she had never met before.

It was confirmed that Jeong Yoo-jeong had a phone call with her father two days before the crime. According to a JTBC report on the 26th of last month, Jeong Yoo-jeong said things to her father implying a warning of murder, such as "If I do something terrible, you will suffer," and "After doing something terrible, I will die too."

Jeong Yoo-jeong had lived with her grandfather alone since childhood after separating from her parents. She was greatly dissatisfied with this environment and reportedly told the prosecution that she felt betrayal and frustration towards her parents.

Through SBS's 'Unanswered Questions,' it was revealed that Jeong Yoo-jeong applied to be a golf course caddy in her third year of high school and hoped for 'dormitory life.' Experts analyze this as reflecting her desire to escape the home where she lived alone with her grandfather.

After failing university entrance exams and civil service exam preparations, Jeong Yoo-jeong's anger was so intense that she searched for 'filicide' online. During the prosecution's search, a note was found in which Jeong Yoo-jeong wrote, "I won't feel relieved unless I kill."

According to the prosecution's psychological analysis, there is an opinion that "Jeong Yoo-jeong seemed to intend to harm a third party to cause pain to her father, from whom she craved affection." It is also analyzed that in the process, she chose a peer woman, for whom committing the crime was easier, as the murder target.

Professor Lee Soo-jung of the Department of Criminal Psychology at Kyonggi University said on YTN The News, "Jeong Yoo-jeong wrote in her notebook, 'I won't feel relieved unless I kill,' but the object is omitted. I thought to myself that the object might be her father," and analyzed, "Did the victim do anything to provoke Jeong Yoo-jeong's anger?"

Professor Lee added, "Whoever she was angry at, the problem is that she replaced her anger onto an easy and defenseless victim as a scapegoat," and said, "Since anyone could have been indiscriminately harmed, this is truly a heinous case."
