Lee Dong-woo's hometown is located in a remote village near Gwangju City, Jeolla Province, and after Yoon Guohong found it according to the address obtained from the investigation, he visited the villagers.

According to the villagers, Li Dongyu did return here on Wednesday night, and also invited a local old man who was kind to him to dinner.

Yin Guohong went to the old man's house under the guidance of the villagers, and the old man also confirmed this.

In this way, according to the testimony of the dash cam, the old man and the villagers, it can be said that Li Dongyu has a sufficient alibi.

Yoon Guohong stood up and was about to report to Kim Yun-ho, when suddenly he saw the photos hanging on the wall, and he said more: "Excuse me, is there any Lee Dong-woo in these photos?" ”

The old man smiled and nodded: "Yes, when I had my birthday last year, he also participated, but he was not happy to take a group photo."

This kid didn't like to take pictures many years ago. So I asked the children to take a picture of him secretly, and when he was gone, I could also look at it and have a thought.

Well, it's the one that the clock is obscuring. ”

Yin Guohong followed the old man's guidance, took off the wall clock on the wall, and did see a photo in the back.

But after seeing this photo, Yin Guohong was stunned.

"You say...... Is this Lee Dong Woo? Lee Dong-woo who works as a teacher at the Gangnam School for the Disabled in Seoul? He asked, surprised.

The old man nodded and said, "That's right, it's him." What, is there a problem? ”

Questions?

It's a big problem.

Because the man in the photo is not Lee Dongwoo at all, but someone else.

When Yin Guohong saw this, he suddenly understood.

Lee Dong-woo and the man in the photo actually share the same identity. They take advantage of this means. An alibi was made.

Lee Dong-woo went to commit the crime. The man drove Li Dongyu's car back to his hometown and appeared in front of everyone to make an alibi for Li Dongyu.

――

Seoul, Cho Sang-hee's home.

Kim Yunho smiled after listening to Yoon Guohong's report.

Lee Dong-woo once again exploited the blind spot of thinking and designed a seemingly perfect alibi.

The investigators will first default to the fact that Jeolla Province is Lee Dong-woo's hometown, and then only need to ask the locals if 'Lee Dong-woo' is in the local area during the investigation.

According to normal thinking, it is rare for a case handler to take a photo of Li Dongyu to ask one by one.

Because whether it is the person who handles the case. Or the local residents know who 'Lee Dongwoo' is.

But the problem lies precisely in this common perception.

Li Dongyu, who was known to the case-handler, and Li Dongyu, who was known to the villagers, were not the same person at all.

It's a simple little trick, but it's very practical.

If you let ordinary investigators like Shen Donghai and the like, they are likely to be deceived by this little trick.

Even Yin Guohong almost caught his way.

"I'm sorry to inform you: your alibi was debunked by my assistant investigator......" Kim Yoon-ho said with a smile as he looked at the calm Lee Dong-woo.

But Li Dongyu didn't have any special reaction, and he still had a flat smile on his face:

"It's very powerful, I can't imagine that there are such powerful people under you. Can you introduce me? Is that Ms. Song Eun-ji who wears glasses? ”

Jin Yunhao shook his head: "It's Investigator Yin Guohong." ”

Li Dongyu's surprised expression flashed: "Hehe, so that's the case." I can't believe that you actually sang a double reed play, it's really embarrassing for you. …… As the winner of the game. You can ask questions now. ”

Kim Yunhao said: "You can explain it yourself, I also want to hear your detailed confession." Because I also have a few questions that I haven't figured out. ”

Lee Dong-woo learned what Kim Yoon-ho had just said. Laughing: "As you wish."

Let's start the story a year ago.

At that time, I had just arrived at the school for the disabled, and I began to take Zhao Dongmin, a child.

In subsequent contact, I noticed that the child often had some scars on his body. Although I asked the kid, he never said how he got it.

Later, Zhang Suying would come to pick up Zhao Dongmin every day, and gradually we became familiar with it. I also asked Zhang Suying about this, but she refused to say it at first.

It wasn't until three months ago that she revealed the truth to me.

Zhao Shangxi and Zhang Suying had previously given birth to a boy with mild intellectual disability, and when the boy was 7 years old, he secretly went into the water because he was disobedient and finally drowned.

At that time, Zhao Shangxi was hit very hard and had a heart disease. After they adopted Zhao Dongmin, Zhao Shangxi gradually recovered.

But Zhao Shangxi has not really recovered, he usually looks very normal, and he is also very good to his wife and Zhao Dongmin.

But once Zhao Dongmin is disobedient, Zhao Shangxi will think of his dead biological son, and his heart disease will attack, and he will punch and kick Zhao Dongmin.

And Zhang Suying has always regarded Zhao Dongmin as her dead child, and she loves and cares for her, seeing Zhao Shangxi beating Zhao Dongmin, she can't bear to step forward to persuade her, and sometimes she will be involved.

Zhang Suying persuaded Zhao Shangxi to receive psychological treatment, but Zhao Shangxi did not listen for the sake of face.

Later, Zhang Suying couldn't bear it anymore and used her neighbor's mouth to expose the incident to the police, but afterwards Zhao Shangxi was furious and almost killed her and Zhao Dongmin.

Zhang Suying was scared, and in the end she didn't tell the police the truth, but changed her words. The whole thing is gone.

It was only after seeing this situation that I made the decision to kill Zhao Shangxi and let Zhao Dongmin get out of the sea of suffering as soon as possible. ”

Hearing this, Kim Yun-ho couldn't help but ask, "I can understand killing Zhao Sang-hee, but why do you want to kill Jang So-young?" ”

Li Dongyu glanced at Jin Yunhao regretfully and said: "You don't understand, in fact, not only Zhao Shangxi fell ill because of the events of the year. So is Zhang Suying.

She loves Zhao Dongmin too much, and she made up for her love and guilt for her dead biological son on Zhao Dongmin.

Once I saw Zhao Dongmin fall at the school gate, Zhang Suying actually licked Zhao Dongmin's wound with her tongue and cleaned it with saliva.

This is already perverted love, and now Zhang Suying loves Zhao Dongmin so much, but after a long time. Once she was stimulated by something. This love will evolve into hatred.

She will become even more terrifying than Zhao Shangxi.

So. I'm going to dispose of this time bomb for Cho Dongmin too. ”

Lee Dong-woo's motive for killing is very clear, which is to protect Cho Dongmin.

But Kim Yunhao couldn't figure it out: "Why don't you solve this matter through judicial channels or the media?" Why do you have to use such extreme methods? ”

Li Dongyu snorted lightly and mocked: "Judicial way? What will speak for the poor? I've reported it anonymously many times, but nothing has been heard from me.

I also broke the news to the TV station, but there was no response, and I only found out afterwards that Zhao Shangxi has a wide range of connections, so I found someone to suppress the matter.

So. The so-called justice, fairness, these things are all deception. We civilians can only solve problems on our own, with our own hands. ”

Kim Yoon-ho understands Lee Dong-woo's plight, because he has encountered a similar dilemma before-calling the heavens and the earth not working.

In the end, he chose a righteous path to revenge, while Lee Dong-woo chose the exact opposite path.

Kim Yunho slowly breathed a sigh of relief and shifted the heavy topic: "Let's talk about the specific case." ”

Li Dongyu was depressed for a while, but quickly recovered. When talking about the case, he even had a faint excitement:

"I spent a month designing this murder plan. It took another month to prepare.

On the one hand, I often visited Zhao Dongmin's home. Learn about the environment of their home. And when talking, intentionally or unintentionally reveal some small stories.

For example, the story of a husband who loves his wife and commits suicide in order to protect her.

In this way, it is implied that the couple loves one person and makes great sacrifices for the other person, so that it can be regarded as true love.

On the other hand, in school, I slowly changed Zhao Dongmin's drawing habits, asking him not to draw my facial features, and after drawing them, I also asked him to change his words, calling me "Uncle Investigator" in the painting.

Because I know that the case that Zhang Suying reported to the police has not yet been completed, and the prosecutor will definitely send someone to investigate, and the person who investigates is the investigator.

So, I came up with the idea to frame the inquisitor and hide my identity for me.

Once everything was ready, I waited for my chance.

Luckily, it didn't take long for your prosecutor to investigate Zhao Shangxi's domestic violence case for the second time.

The investigator named Shin Donghae also came to the school to ask me about the situation.

That's when I knew the opportunity had come.

On Wednesday, I first went to Zhao Shangxi's house in the name of visiting, and during the conversation, I lied and told Zhao Shangxi that Zhao Shangxi Zhao was disobedient at school and wanted to go into the water without permission.

Hearing this, Zhao Shangxi thought of his son who had died before, and immediately became furious. Zhang Suying saw that the situation was not good, so she hurriedly pulled Zhao Shangxi back to the room.

I took advantage of this to say goodbye in advance, deliberately making a noise out of the door, and pretending to leave. Then he quietly returned to the house and hid under the coffee table with a cloth in the living room.

Because Zhao Shangxi's mental illness began to attack again, he chased Zhao Dongmin to fight. And Zhang Suying was busy appeasing, and the three of them didn't notice me.

So, I hid under the coffee table for the whole day. During the day, he took advantage of Zhang Suying to go out to pick up Zhao Dongmin and came out to solve physiological problems.

On Thursday night the next day, I used my mobile phone to send a text message to Zhao Shangxi and Zhang Suying under the coffee table, conveying what the substitute teacher always said: Zhao Dongmin was disobedient at school again, and this time he really went into the water.

And told them that I was going to visit the house in a moment.

After seeing the text message, Zhao Shangxi really fell for the trick and became angry again, even much more serious than the previous situation.

Seeing that the situation was not good, Zhang Suying stopped Zhao Shangxi, and finally the two scuffled together in the bathroom.

At this time, I took advantage of the chaos to appear and went to the bathroom to help Zhang Suying stop Zhao Shangxi, and deliberately stimulated Zhang Suying, saying that sooner or later Zhao Shangxi would kill her and Zhao Dongmin by mistake due to mental illness.

Hearing this, Zhang Suying also began to become excited, and in a hurry, she stabbed Zhao Shangxi to death with a toothbrush in the bathroom.

Because I texted that I was going to visit my home, Zhang Suying thought that Zhao Dongmin opened the door for me during their scuffle, and he panicked after the killing, so he didn't think much about it.

After that, I reassured her and made her drink the water containing sleeping pills.

………

You all know the rest, for the sake of different loves, Zhao Shangxi and Zhang Suying both sacrificed and took the initiative to lock the door, forming two secret rooms.

I left the scene the next morning after carefully cleaning up the evidence left at the scene. ”

Lee Dong-woo's plan was perfect, and his design of the time of the crime successfully interfered with Kim Yoon-ho's line of sight and took advantage of the time difference to mislead Kim Yoon-ho's investigation.

But Kim Yun-ho still has a little question: "How did you leave on Friday morning without arousing suspicion?" ”

Li Dongyu explained with a smile: "Call someone first and ask him to pretend to be a courier to deliver the courier." Then we swapped costumes. I left in the courier's clothes.

Then he hid in the apartment, and waited until the bodies of Zhao Shangxi and his wife were found and the police entered in large numbers, and then he took advantage of the chaos to leave.

Anyway, the police could see at a glance that Zhao Shangxi and his wife had been dead for a long time, and they would think that the murderer had already fled the scene.

Therefore, the police would not have cordoned off the apartment building, would not have carried out detailed checks on people entering and leaving, and he would have easily left with the chaotic crowd. ”

Hearing the information of this accomplice, Kim Yun-ho immediately asked:

"I understand your motive for committing the crime, but why would that person be willing to help you? If you're not mistaken, that person is the other 'Lee Dong Woo' who shares the same identity with you, right? ”

Li Dongyu nodded and said with a meaningful smile: "Since he caught me, he will also take the initiative to turn himself in." As for the reason why he did this, you have to guess slowly.

Isn't it boring that everything is told to you? Haha......." (To be continued......)
