The identity of Army officer Yang Kwang-joon, a suspect in the murder of a military officer in an internal affairs relationship, and the damage and detention of the body, has been disclosed. The situation of Yang's planned crime is also being revealed one after another. Let's take a look at this case. Lee Woong-hyuk, a police professor at Konkuk University, is here. Welcome. Yang Kwang-joon's personal information has been released, and it seems to be the first time that a suspect in military status has been disclosed.

[Lee Woong-hyuk]
That's right. Since the establishment of the suspect identity disclosure system in 2010, 57 murder suspects have been disclosed. Among them, this was the first time I had a military status and I think I can organize it like this, as I am the 58th person to disclose my personal information.

It can only be described as a so-called fragmentation murder in the media. In that case, 9 cases were released, but this time it was the 10th case. So, in the end, it is proof that he would not have done such an act that is close to crime due to the nature of his job as a soldier, but this issue is even more shocking in that regard.

When a person in this profession, who is supposed to take the lead in national security through training, actually sees a significant officer in the Cyber Operations Command as a result, he or she will be seen as a murder of an ally. Another thing we should pay attention to is that the recent problem of social murder, the victim was also a woman, is still working within the military organization. So, according to a recent statistic, when combined with a statistic that says that women are being killed by men every three days, this is not an open case that is far more than just a murder.

It would be nice if you could show the picture a little bigger. Yang Kwang-jun, please show us the picture. I'm 38 years old. Now you look like you're wearing a military uniform, and can you show me a mugshot picture? Yang Kwang-joon's face due to the disclosure of personal information... This is a mug shot. That's why the most recent image was revealed. But I hear a lot of things, but what kind of person was he? I heard that he was a nice person who took good care of his juniors.

[Lee Woong-hyuk]
The general reputation was such an officer who had a poor and sincere military life for his juniors and was highly intelligent and highly anticipated with various grades.

[Anchor]
Isn't promotion fast, too?

[Lee Woong-hyuk]
It is known that he is scheduled to be promoted to lieutenant colonel at the age of 38. Then, compared to the average figure, it can be seen that you have been promoted quite quickly. Because in general, the average age of a lieutenant colonel is in his early 40s, if a little later, in his mid 40s, but now that suspect of murder is 38 years old, he was promoted fairly quickly.

Of course, there are some differences depending on the disease and so on.Ma's promotion to lieutenant colonel at the age of 38 is thought to be a part of how he can commit such a terrible crime when he sees his grades, reputation, skills, leadership, and even the fact that he is now recognized by the Cyber Operations Command.

[Anchor]
A person like this is usually his demonic nature in criminal psychology. Is it possible to see it like this that I've been hiding something like that? How can I analyze it?

[Lee Woong-hyuk]
When summarizing the reputation of a felon whose personality characteristics are usually very terrible, it is common to say that what the neighbor talked about was really calm and quiet, sincere, and that I did not know that I would do this. In that case, it's possible that they had two so-called egos.

In other words, the appearance of trying to live up to one's self, social expectations, and reputation. However, there is a possibility that something like anger control disorder and strong expressive motives for retribution were circulating inside. Furthermore, in this case, we also point out that the use of expertise for wrong crimes is undeniable.

[Anchor]
Why did they go so far as to kill and damage the body? I was most curious about the motive of the crime, but first of all, Yang Kwang-joon is known to be married and has a child, and the other woman is single. It's now known that it was an internal relationship, right?

[Lee Woong-hyuk]
I think the internal relationship began early this year. In the meantime, conflicts and disputes have been known to be frequent since June due to various issues. For example, it may be pressure on these social relationships that are not appropriate. Or, Lieutenant Colonel Yang is being transferred to another unit as of October 28, and the female victim seems to have had a continuous dispute with the contract terminated as of October 31.

There was also a quarrel in the morning of the day and in the situation of carpooling. And if you look at it, it's linked to a certain emotion or pressure on social status, or any more pressure on this relationship, so I suggest that men or women stop having that relationship first, and that's my presumption.E, not very well accepted in that.

The woman may have suggested it first, or the lieutenant colonel may have suggested it first, but there is a high possibility that this military officer thought that a certain social relationship should be completely terminated in this situation as the inflection point of October 31 is approaching.

Its rationale itself is the mobile phone or computer anti-theft wire that was in the car when you saw how it was killed. The act of strangling using that wire is a form of so-called strangulation. This can only be seen as the use of wires because there was a plan and mind to completely overpower the other person, necessarily resulting in terrible consequences, and to put it simply, to death.

If so, I don't know if it's a coincidence, but after a few days, I'll go to a new job, and if the trigger for the various conflicts and mental burden itself was a fight in carpool on that day anyway, it seems that the plan in the car was actually a wire that I thought I should end everything completely.

[Anchor]
So it was intended to kill, that's how you see it.

[Lee Woong-hyuk]
That's right. There is a possibility that the item was accidentally in his car while transferring the wires, but if you say you thought about it from the beginning, you should kill him at 3 o'clock. In other words, the most effective and quick way to die is to actually reinforce that the so-called strangulation, the use of strings to compress the carotid artery, came to his office at 7:25 on the same day and what he searched for was how to make a fake license plate, and it would be all back and forth.

[Anchor]
That's why I killed him in the afternoon, but he searched for a fake license plate in the morning. Then, it's highly likely that you've made up your mind when searching for the fake license plate, right?

[Lee Woong-hyuk]
That's right. Why do we need a fake license plate after all? In the end, the only way to commit a terrible killing and not be discovered in the processing of a body in front of you is to send false information to someone else's vehicle, not to your own vehicle. As a result, the fact that the target searched on Internet portals was identified with the same license plate as the color of his vehicle, which is more than the average killer thinks, is that we are deceptive information about security, pressure on the investigation network, and information authorities. I'm sending you fake information. It's a way for a person who's trained in security to think about it, and you can evaluate it with a very appropriate and intelligent way of using these things.

[Anchor]
The fact that many people went to the Cyber Command and used the technology to prevent their crimes is that they deleted their phone records and called the police as if they were victims to postpone them. How can I see that?

[Lee Woong-hyuk]
In the end, it's an extension of what I told you. It's what we call fake texts. The military intelligence authorities call this deceptive information, which distorts facts with fake information. In order to continue to respond to the survival as if he were alive, he sent a text message to the victim's mother saying, "I'll go somewhere for a while and don't worry because I won't come home for a vacation." And as you pointed out for a moment, he also did such a hypothetical act to confuse the investigation with the police report itself.

[Anchor]
But you're saying you called her pretending to be a victim. So you're saying she made a female voice?

[Lee Woong-hyuk]
What's the context of it? It's the 26th. I think he was on his way to kill him and maybe dump the body the next day. At that time, my mother reported to the police that morning. Therefore, from the perspective of Gwanak Police Station, I was curious about the whereabouts of the victim woman, so I sent her a text again. Then, don't you have voice talk on Kakao Talk?

I've sent this as well. But the person who has this phone is Lt. Col. That's why I responded to voice talk as if I were a victim. So what did you say on Voice Talk? In fact, Mi-gui said she wanted to cancel the report itself, but for this cancellation to be official, it must be made through 112 reports.

[Anchor]
That's not registered.

[Lee Woong-hyuk]
So I ended up reporting 112 again. At the same time, he tried to make a voice like a woman in this situation, and eventually asked me to cancel the report because I'm on a highway now, but he also tried to pretend to be a victim.

[Anchor]
What surprised many people was that they were the first offenders of murder, so how can they even think of damaging the body like this? I can't help but be surprised by the horrors. What kind of psychology can this lead to the destruction of the body?

[Lee Woong-hyuk]
There are two things. Once we completely incinerate the body and don't find it, we'll begin to prevent the identification of the suspect in this crime. In other words, there is one such way to avoid arrest.

Second, there are many studies that actually try to satisfy conflicts, complaints, and violent expressions that occur in various forms of internal relationships psychologically.

As a result, eight plastic bags have now been found in the Bukhangang River. So, if you don't throw this away as it is, it becomes a clue to who this body is, so you put heavy stones together in this plastic bag so that you can't think of it at all.

[Anchor]
It was very meticulous.

[Lee Woong-hyuk]
Yes, but it's actually a structure that comes to mind when there's decayed gas, so about a week later, it's November 2, when a high school student found it and reported it.

[Anchor]
Some analysts say that they are obsessed with their honor when looking at the part where they filed an injunction to prevent personal information disclosure.

[Lee Woong-hyuk]
It's actually a representation of the damage to our face and the pressure of knowing who the suspect is. Moreover, the fact that an officer and a person who protects national security became a murderer itself works as a considerable burden when he feels it, so the five-day grace period and the five-day grace period for personal information have been newly created since the beginning of this year. But using this new system, they immediately applied for an injunction for suspension of execution of disclosure. In the end, it was not accepted by the court.

[Anchor]
I think that many people were more enraged by the fact that they tried to protect their honor after committing such a thing. This has been Lee Woong-hyuk, a professor of police department at Konkuk University. Thank you.
