"Uncle Investigator."

In the end, Zhao Dongmin revealed the identity of the fourth person in the painting.

But this sentence was like a spring thunderbolt, which shook people's hearts.

"This ......" Li Dongyu looked at a loss.

"......" Li Huina covered her mouth and froze in place.

Kim Yunho looked at Zhao Dongmin with deep eyes, not knowing what he was thinking.

Could it be that the fourth person who appeared at the scene of the crime was really Shen Donghae? He's an inquisitor! And when Zhao Dongmin saw Shen Donghai, he also showed a very frightened look.

In addition, surveillance footage shows that Shin Donghai also came here at the time of the crime and stayed for a while. There are also Shen Donghai's fingerprints and hair at home.

All this indicates that Shen Donghai is the fourth person.

Lee Hye-na looked at Kim Yoon-ho with a shocked expression, but Kim Yoon-ho didn't say anything and had no expression on his face.

He picked up more than a dozen paintings drawn by Zhao Dongmin and carefully looked through them one by one.

The plot depicted by Zhao Dongmin in the painting is not much different from what they had speculated and simulated before.

It's just that there is an extra plot of 'Uncle Investigator' drugged in the cup and then fed Zhang Suying.

This painting also explains why a large amount of sleeping pill residue was detected in Zhang Suying's body.

It turned out that it was the 'Uncle Investigator' who first fascinated Zhang Suying, and then persuaded and induced Zhao Dongmin to express his 'love' wrongly, and finally made Zhao Dongmin the murderer of Zhang Suying.

"It's so troublesome to do this, why is Shen Donghai... No, it was that person who didn't kill Zhang Suying personally. Instead, use such a troublesome method? ”

Lee Hye-na came behind Kim Yoon-ho at some point. Asked as he looked at the picture.

Kim Yun-ho said lightly: "His purpose is to hope to form a second secret room. If it was he who did it himself. Zhang Suying will not take the initiative to lock the door.

Only when Zhang Suying was unaware and unconscious, and saw that she was killed by her beloved son Zhao Dongmin, she would reveal her great maternal love and take the initiative to lock the door of the room, wanting to help Zhao Dongmin hide the evidence of the murder.

In this way, two perfect locked room murder cases will be formed, which will greatly increase the difficulty of handling the case, and ultimately help him hide his identity. ”

Lee Dong-woo continued the topic and said: "It's a pity... That person didn't know that Zhao Dongmin also had the ability to draw. It can restore the scene at the time of the case for the case handler. Eventually, his true identity is revealed. ”

Li Dongyu held Zhao Dongmin in his arms, gently stroked his back, showed infinite sympathy, and muttered:

"It's really hard for this child to be used like this to kill his adoptive mother with his own hands."

"Hey......" Kim Yunhao also had a look of unbearable loneliness on his face, and instructed Li Huina:

"You stay and help take care of Zhao Dongmin and see if he can think of anything else. Notify me of a new discovery.

I'm going to rush back to interrogate Investigator Shin Donghae and Investigator Yin Guohong, who is deliberately shielding. ”

Li Huina nodded sneeringly. She was still in a state of extreme shock and sympathy.

Kim Yunho nodded at Teacher Lee Dongwoo again, "I'll leave it to you here." ”

After speaking. He turned and walked out.

――

After leaving the room, the angry and lonely expressions on Kim Yun-ho's face disappeared, and the cold temperament reappeared on his body, and a cold smile appeared on the corner of his mouth.

It's like a different person.

When Kim Yun-ho walked out of the apartment building, he saw Yin Guohong squatting at the entrance of the parking lot of the community, holding a bowl of instant noodles and eating deliciously.

Jin Yunhao smiled, took out the car keys and walked to the parking lot, and when he passed by Jin Guohong, he glanced at the bowl of instant noodles, "Why didn't you make an extra one?" I didn't eat either. ”

Yin Guohong hurriedly stood up, took a mouthful of grease stains, and said with a smile: "Hehe, I didn't expect you to come out so soon, so I ate it myself." Why don't you give this bowl to you? ”

Kim Yunho didn't answer, there were only a few noodles floating in the bowl, did he take it and drink the soup.

He ignored Yin Guohong and walked directly to the Hyundai SUV, intending to return to the unit. Yin Guohong followed behind and drank a few more sips of noodle soup, and reluctantly threw away the instant noodles before getting into the car.

After the two got into the car and sat down, they both resumed their serious expressions.

Yin Guohong was the first to ask: "Jin Cixi, after I left, did you find anything else?" ”

Kim Yunhao nodded and briefly said about Zhao Dongmin's painting.

After listening, Yin Guohong sneered: "This method is still real and clever."

First of all, everything was arranged, so that all the evidence at the scene pointed to Shen Donghai. Then let Zhao Dongmin, who is mentally retarded, draw a picture to testify against Shen Donghai. Now the human and physical evidence are all gone.

Although Zhao Dongmin is mentally retarded, his testimony may not be accepted by the judge, but it will still be used as an important reference.

If this case is closed now and Shen Donghai is prosecuted as the murderer, it is very likely that Shen Donghai will be found guilty in court.

What are you going to do now? Is it to investigate Shin Donghae, or is it ......? ”

Kim Yunhao frowned: "Are you testing me?" ”

Yin Guohong smiled to hide his embarrassment and said, "Where... Where. ”

Kim Yoon-ho stared at the scenery in the distance through the window glass and said, "I never doubted Shin Donghae from the beginning.

First of all, these two murders were obviously planned for a long time.

And the murderer who deliberately kills has to go through a period of mental changes before committing the crime, until his mind is twisted, until he makes the decision to kill. There are long and short parts of the process.

The more deliberate and brutal the killing, the longer this change in mind.

But looking at Shen Donghai's situation, he has been in contact with the victim for no more than 4 days, and he usually moves under the noses of me and you, and there are no signs of abnormality.

Therefore, there are no objective conditions for him to carry out this process of mental change.

Also, all the signs in this case show that the murderer needs a detailed and careful plan, and the key is to be familiar with the mentally disabled Zhao Dongmin, so that Zhao Dongmin can be obedient. If you want to be familiar with Zhang Suying, you can let Zhang Suying drink the water that has been given sleeping pills.

In 4 days, Shen Donghai couldn't complete these tasks at all. ”

After listening to Kim Yun-ho's analysis, Yin Guohong nodded in agreement: "Not bad." If Shin Donghae is the murderer. A lot of logic doesn't make sense. ”

The two looked at each other. At the same time, I will smile.

The conflict that broke out in Zhao Shangxi's house before was simply acting.

When Kim Yoon-ho began to shift the conversation to Shin Dong-hae, Yoon felt a little strange.

Because Kim Yun-ho was the first person to believe that Shin Dong-hae was innocent, otherwise he would not have caused trouble and personally came to handle the case to clear Shin Donghae's suspicion.

Later, when Kim Yunho was yelling at him, Yoon Guohong confirmed that Kim Yunhao was acting.

Because Kim Yoon-ho will not say the phrase 'go back to the Gangnam District Prosecutor's Office' to people he knows. In order to save time, he would say 'go back to the unit' or 'go back to the district prosecutor'.

Therefore, based on this alone, Yin Guohong judged that Kim Yunhao was acting.

As for who to watch......

"Jin Cixi, do you also suspect that teacher Li Dongyu?" Yin Guohong asked.

Kim Yunho didn't nod or shake his head: "In this scene we played, the real audience is not necessarily Lee Dongwoo."

Yes, Mr. Li Dongyu is indeed very suspicious.

First of all, the only people who can induce Zhao Dongmin to make murderous actions are those close to Zhao Dongmin. Mr. Lee Dong Woo fits this point.

Secondly, Mr. Li Dongyu is too familiar with Zhao Shangxi's family. He seems to have been here many times.

In the end, it was he who has been guiding us on how to find clues in Zhao Dongmin little by little. ”

Yin Guohong's eyes lit up: "Yes, I have always doubted this Li Dongyu." That's why you deliberately acted in this drama and separated me and asked me to secretly investigate Lee Dong-woo? ”

Jin Yunhao nodded, and shook his head again: "It's for you to secretly investigate Li Dongyu." But don't investigate with suspicion of his thoughts. It's a routine. ”

Yin Guohong was a little puzzled this time: "Why? ”

Kim Yun-ho knocked on the steering wheel of the car and slowly analyzed: "

None of us doubt it now. Unless conclusive evidence emerges.

From the very beginning, I had the feeling that we were being played like monkeys!

The murderer first arranged two secret rooms, and then gave us all kinds of unbelievable clues for us to find and make judgments. In the end, these analyses and judgments lead us to a dead end.

Later, the clue of Zhao Dongmin appeared, and the things he pointed out once again shifted our attention to Shen Donghai.

In other words, we are now being led by the nose by the murderer. We will go what He tells us to go, and we will do what He tells us to do.

Can you guarantee that this Lee Dong Woo is not the second decoy thrown by the murderer?

From now on, we abandon all clues that appear on the scene and re-investigate. Take the time of the crime as the main investigation point, find out all the suspicious characters first, and then investigate them one by one.

I'm ming, holding back the murderer's gaze; You're secretly operating to investigate together. ”

After Yin Guohong listened, he suddenly realized, and then he looked at Kim Yunhao with some shock, he couldn't imagine that Jin Yunhao could think of such a back-to-basics method in a short period of time.

The place where the crime was committed, the time when the crime was committed, and the motive for the crime.

These three points are the main direction of investigation in handling cases.

Usually, the investigator first knows the place where the crime was committed: finding evidence and analyzing suspicious points. The suspects are then identified accordingly.

Then check whether the suspect has the time and motive to commit the crime.

This is the normal process of handling cases.

But now, in order to get rid of the interference created by the murderer, Kim Yun-ho decided to do the opposite.

First of all, temporarily abandon the investigation direction of 'the place where the crime was committed', start with the 'time of the crime', and finally find out the suspect's 'motive for committing the crime'.

In this way, it is deduced in reverse to see if the suspect found is consistent with the evidence left at the crime scene.

Although this method is a bit 'stupid', it is the most suitable direction for handling cases at present.

"You have arranged the crime scene seamlessly, I don't believe you can still arrange the crime time perfectly?"

Now I'm going to do the opposite and catch you off guard! ”

Kim Yunho looked out the window and smiled confidently. (To be continued......)
