The reality of brutal and ugly criminals was tracked and revealed to the end in 'Brave Detectives 4.'
In the 36th episode of 'Brave Detectives 4', which aired on the 30th, grants were made by Song Young-beom, chief of the integrated criminal team at Incheon Nonhyeon Police Station; Ahn Jae-hwan, an inspector from the violent crime team at Incheon Namdong Police Station; and former Superintendent Yoon Oi-cheol and Deputy Chief Kim Jin-soo from the scientific investigation team (KCSI), who presented their case files.
The first case began with a report that a person's feet could be seen from a window of a building across the street for the second day. Upon opening the door, the body of a young man in his 20s was found face down on the floor, bleeding, surrounded by broken soju bottles, cigarette butts, and bloody footprints. An autopsy revealed over 40 stab wounds. With the victim's computer, mobile phone, and credit card missing, the investigation team traced CCTV footage using a canceled receipt from a singing room near the victim's home two days before the incident. They then captured the presence of Mr. Yoo, who had an exceptionally long chin (a pseudonym) and had been with the victim. He had entered the victim's home and left alone.
The victim, who had been drinking with friends the previous day, later headed to the bustling area alone and encountered Mr. Yoo with a tout. According to the tout, Mr. Yoo said he wanted the person who took him to a bar to be found and then went to drink with the victim. Targeting the victim's money, Mr. Yoo exhibited behavior to confuse the route by transferring taxis multiple times after committing the crime. He also visited illicit businesses. The investigation team began inquiries focusing on the drop-off and pick-up points after capturing footage of Mr. Yoo changing clothes.
Ultimately, Mr. Yoo was arrested at a goshiwon (a type of lodging house). In his 40s and unemployed, he had sold the victim's laptop, from which the victim's DNA was detected on a knife found inside. While detained, he repeatedly uttered incomprehensible phrases such as "The person has come" and "There is another being inside me." Mr. Yoo was sentenced to 20 years in prison due to alcoholic psychotic disorder and symptoms of schizophrenia.
The second case introduced by KCSI began when police discovered a man loitering in a residential area. Upon seeing the police car, he suddenly changed direction, and during a stop-and-frisk, it was found that his ID photo did not match his actual face at all. He possessed three mobile phones, one of which had been reported stolen a year earlier. In the trunk of his vehicle, three resident registration cards, an external hard drive, surgical gloves, knives, 14 pieces of women's underwear, and homemade adult products were found.
The external hard drive contained downloaded videos of sexual violence and photographs secretly taken of women's body parts, along with pictures of 23 identification cards. While tracking the owners of the ID cards, the investigation team confirmed that one of them belonged to a past murder victim. The victim was found in a state of partial nudity in a room, and blood from the victim was detected in a cosmetic bottle, indicating it had been used as a tool for sexual assault.
After diligently persuading the man, a detective who had been observing the perpetrator managed to get him to confess not only to this case but also to an earlier murder case he referred to as his "own playground." The victim was found in a naked state with a branch over 40 cm long inserted into her body. He claimed the victim had looked down on him. Notably, in both cases, the perpetrator's consistent behavior pattern involved taking the victims' underwear.
The culprit was Lee Dae-young, arrested in 2009. He lived with a woman in a common-law relationship and maintained a double life by going out every night under the pretext of deliveries or driving services. Although he claimed to have started watching videos of sexual violence due to past similar offenses, this was not verified. Exhibiting a distorted mindset that "if many people do it, it is normal" regarding sadistic behavior, he was sentenced to 22 years and 6 months in prison.
