Controversy is growing over the leak of a situation report containing the identity of Park Dae-sung and the victim who were arrested for killing a teenage girl. There are various analyses about Park Dae-sung's smile after the crime. There was also an analysis that it was similar to the behavior of consecutive murders. I'll connect the profiler of Bae Sang-hoon and take a closer look. Are you out?

[Bang Sang Hoon]
Hello, I'm Bae Sang-hoon.

[Anchor]
How are you? Now, the report on the day of the incident has been leaked online and is spreading. The report is prohibited from being leaked to the outside world, so how did it get leaked?

[Bang Sang Hoon]
To be exact, it is now known as a report on the arrest of suspects. There is a different part from the situation report. So this is what you're reporting to the upper echelons, so it's likely the latter. The content itself is a little different. Anyway, it shows the identity of the suspect, the victim's identity, and the approximate crime, and as I said earlier, it is highly likely that someone at the line reporting to the upper level took a picture of it and posted it on the Mom Cafe, or that it was leaked in that way.

[Anchor]
As you said, if this was leaked from the police, would it have been intentional to some extent?

[Bang Sang Hoon]
Yeah, because police would have been fully aware of the leak breaking the law for themselves, and then they would have had intentions. Intent is, for example, intentional because your argument may have public intentions or private intentions.

[Anchor]
There is also an investigation into Park Dae-sung's motive for the crime, and the most shocking thing was the smile caught on CCTV. I heard there have been criminals who have done this before?

[Bang Sang-hoon] There's
. So to speak, criminals who usually use this concept of serial murder have a similar form of psychological smile as their muscles in their faces unwittingly change to a state of arousal and excitement after murder. Think of the face of the movie Joker, like the Joker. There have been many cases of such conditions.

[Anchor]
Similar murders we can remember, what are some?

[Bang Sang Hoon]
That's how the criminal in the Seohyeon Station case can be seen. And it can be said that the same person as Joseon in the Sillim Station case is in a similar state. But it's not filmed, so we can't see it on video, but we can actually infer that state of mind.

[Anchor]
You just said serial murder, how is it different from the usual serial murder?

[Bang Sang Hoon]
Usually, serial killing is called serial killing. A serial murder is a serial murder in which an excited state cools down and appears again after a long time. Successive murders are a state of excitement because the excitement is sustained. In a state of excitement, you continue to attack the victim as you can see. That's why it's called serial murder, and the word "prime mother" is used. It's not called killing because it's connected in one space.

[Anchor]
If the excitement continues, could an additional more dangerous situation have occurred in the future?

[Bang Sang Hoon]
That's right. The reason why Park Dae-sung's response was a bit lacking was because he wandered around for an hour or two with a weapon in an excited state, and this could kill anyone in any form. In the case of the United States, it's because of the fact that when you have a firearm and you have a spring mother, you kill 10 or 20 people.

[Anchor]
Park Dae-sung and he has a history of violence. Then, can the criminal record of violence be seen as an extension of the serial murder?

[Bang Sang Hoon]
If there is a high sensory acceptance of a stimulus, it may be clearly related to the history of violence. Because ordinary people endure it and move on, but in this case, if you explode and use violence against others, it's meaningful in terms of violence.

[Anchor]
And I'm looking at Park Dae-sung right now, and if you look at Park Dae-sung's neck, there's a tattoo that you can see in front of him. Analysts say that this tattoo must have been violent, so how do you analyze the profiler?

[Bang Sang Hoon]
Violent can be divided into two main categories. There can be aggressive and defensive. So, there is an aggressive, defensive aggression that says, "What if you touch me all the time because you are small and small?" and violent aggression exists. In the case of Park Dae-sung, maybe the latter, for example, passive aggression, defensive aggression. Then, will that be related to the violent character? There is such a question. But if you just say that Park Dae-sung is violent, that can't be the answer. You have to go in analytically.

[Anchor]
And earlier, you talked about how to deal with the police, but there was a story that Park Dae-sung reported just before the crime and that Park Dae-sung had an interview with the police. It was 20 minutes before the crime. Was there any situation where the police could capture the situation a little more?

[Bang Sang Hoon]
When the patrol team was dispatched, my brother asked me to respond because he thought his brother was going to commit suicide, but the police usually with high experience should have understood what the situation was. Usually, in such cases, it is not about committing suicide, but there is a possibility of other forms of crime, so if you understand it in the form of reporting to 019 and tracking the location, I think the police there should have looked at the situation from a broader perspective and waited for a while. Because you don't come back right after the interview, so if you wait outside for about 10 to 20 minutes, the next response comes out. I think that was a little insufficient.

[Anchor]
Is there any response manual that sets such a principle?

[Bang Sang Hoon]
No, there is no such thing. Because this is purely this form of serial murder and this kind of violence is still lacking in our police. It's not analytical.

[Anchor]
We need to look at it more carefully, but Park Dae-sung said he doesn't remember the crime because he drank now, but he's changing his words little by little. What areas should the police focus on when investigating in the future?

[Bang Sang Hoon]
From the current situation, it's not that I don't remember because I drank a lot, but I think I just decided on an alibi. Because two or four bottles are controversial. And looking at the police right away. Then, planning can be in your head, but there can definitely be a recorded part such as writing a note. If you find that part, you'll get a high sentence if you ask for it in court.

[Anchor]
He said that we should pay attention to our usual records rather than testimony. I connected the profiler of Bae Sang-hoon and took a closer look. Let's stop listening to what we said today. Thank you.
