The discovery of two sisters murdered inside an apartment took a shocking turn when investigators found the business card of an active-duty detective at the scene. The brutal acts later uncovered left director Kang Yoon-sung stunned, prompting him to exclaim, “This person isn’t human.”
Episode 6 of E Channel’s original web variety show Detectives’ Talk 3 will be released at 7 p.m. on November 13 via the YouTube channel Detectives’ Talk. Director Kang Yoon-sung, known for directing The Outlaws and Disney+’s Big Bet, will appear as a guest.

On the show, Lee Yi-kyung introduces a murder case involving two sisters that occurred in 2000.
The case came to light when a delivery driver went to an apartment to drop off a package. Noticing that the front door of one unit was open and hearing no signs of anyone inside, he looked into the apartment.
Inside, two women were found dead. It was later revealed that they were sisters, making the discovery even more heartbreaking.
What made the scene particularly puzzling was evidence that someone had rummaged through the apartment, even though the valuables had been left untouched. Investigators also obtained a witness statement from someone who had seen a suspicious man in the area in the early hours of the day the crime took place, prompting a full-scale investigation.
At the time, a series of crimes, including incidents targeting young children and other murders, had occurred in the surrounding area, heightening residents’ anxiety.
Composite sketches of suspects had even been produced in some of the cases, but investigators struggled to track down the perpetrators.

While reviewing the material, profiler Kwon Il-yong looked at one of the sketches and recalled something from the past, saying, “I remember this case.”
Then, the investigation team made an unexpected discovery at the sisters’ apartment: a business card belonging to an active-duty detective. Surprisingly, the detective had previously been in charge of a case involving one of the victims.
As the detectives revisited the case, they uncovered unexpected information and began tracking the suspect’s movements using newly discovered clues.
After hearing the shocking details of the crime, director Kang Yoon-sung could not hide his anger toward the perpetrator, exclaiming, “This person isn’t human.”
Kang Yoon-sung also named financial crimes as a subject he has recently been interested in, leading to a discussion about human greed and the pursuit of money.
Profiler Kwon Il-yong explained that some financial criminals manipulate and control others with remarkable cunning, even treating human lives as tools to achieve their own goals. He also shared his insights into the psychology behind such crimes.
During the episode, Kwon Il-yong also spoke about his friendship with Kang Yoon-sung, revealing, “We first met while having a meal with director Jang Hang-jun, and we’ve become much closer since then.”
Meanwhile, Detectives’ Talk 3 is a web variety show that examines the investigation processes behind real-life criminal cases and the psychology of offenders alongside detectives and criminal experts. New episodes are released every Friday at 7 p.m. on the YouTube channel Detectives’ Talk.
