[Asia Economy Reporter Han Seung-gon] It has been confirmed that Kim Taehyun (25), who killed a woman in her 20s and her entire family because he felt ignored, stayed at the crime scene for three days. During that time, he exhibited bizarre behavior such as drinking alcohol and attempted to destroy evidence to cover up his crime.

Experts analyzing this meticulous and brutal crime suggest it likely stemmed from delusional jealousy. Delusional jealousy is a type of delusion where a person irrationally believes that everything around them is related to themselves and interprets these things as having special meaning to them.

According to media reports, the victims were a family of three: A (59), B (24), and C (22), who are mother and daughters. Earlier, on the afternoon of the 23rd of last month around 5:30 PM, Kim is accused of entering B’s home in Junggye-dong, Nowon-gu, Seoul, by pretending to be a delivery courier. He then killed B’s younger sister who was alone at home, B’s mother who returned about five hours later, and B herself who came back an hour after that.

Kim Taehyun deceived the victims by pretending to deliver a package and entered the house carrying a weapon he had prepared in advance. The victims suffered fatal wounds to their necks and died at the scene.

Afterward, Kim began exhibiting bizarre behavior. He stayed at the crime scene for three days, during which he ate meals and drank alcohol. He also attempted to destroy evidence by trying to reset his mobile phone. Eventually, he was apprehended by the police with multiple self-inflicted stab wounds on his neck, wrists, and abdomen.

Criminal psychology experts analyzed that Kim’s crime was likely not a spontaneous act but a carefully planned one. According to JTBC, Kim had prepared the tools he used for the crime in advance. Experts also consider his act of deceiving the victims by pretending to be a delivery courier to gain entry as part of the planned crime.

Professor Gong Jeongsik of the Department of Criminal Psychology at Kyonggi University, speaking to the media outlet, emphasized, "The fact that he disguised his identity and broke into the house of a woman he was stalking indicates premeditation."

It is also analyzed that the murder of B’s younger sister, the first victim he encountered at the house, and the subsequent killings were likely premeditated actions.

According to Dong-A Ilbo, before breaking into the victim’s home, Kim Taehyun searched for "vital points" on his mobile phone. This has led experts to believe that he meticulously planned the murders. An autopsy of the three women confirmed that all victims suffered fatal wounds near the carotid artery in the neck area.

Professor Lee Sujeong (Kyonggi University, Criminal Psychology) pointed out, "The fatal wounds were in areas that are unlikely to be stabbed accidentally during a struggle. Unless there was clear intent, it would be difficult for such injuries to occur. This suggests he wielded the weapon with the intent to kill from the start."

Kim reportedly stated that he committed the crime because the victim refused to meet him. However, there is an opinion that this is a form of delusion. The crime is believed to have originated solely from Kim Taehyun’s delusional perception of a relationship, not from any actual relationship with the victim.

Professor Lee analyzed Kim’s prolonged stay at the scene by saying, "He must have stayed there because he wanted something. It is presumed that he may be a psychopath with some form of sexual deviation and paranoid delusional jealousy."

Currently, Kim Taehyun is reported to claim that the murders of B’s younger sister and mother were "accidental." However, experts consider this claim one-sided, given the premeditation evident in preparing the weapon, deceiving the victims by posing as a delivery courier, and the circumstances suggesting he prepared for the crime around victim B. Kim is scheduled to be transferred to the prosecution once the investigation concludes.
