After asking Taeyeon and Yoo Jae-seok, Kim Yoon-ho has a more comprehensive understanding of director Cho Hyo-jin.

Subsequently, he interrogated Cao Xiaozhen in detail for the second time, carefully observing Cao Xiaozhen's facial expressions as he spoke.

It seems that Cao Xiaozhen is very suspicious, and Taeyeon broke the news that Cao Xiaozhen had a violent incident. But with observation and detailed analysis, Kim Yoon-ho knew that Cho Hyo-jin was not the real murderer.

The incident in which Cao Xiaozhen almost got into a fight occurred in the last few days, only two days after the case occurred. If he is really the murderer in this case, how can he expose himself so rashly and arouse suspicion.

The murderer in this case is a high-IQ guy, and he will definitely not make such a low-level mistake.

Therefore, Cao Xiaozhen is also a misleading option.

After leaving the interrogation room, Kim Yunhao immediately received a call from Yoon Guohong:

"Kim Ji-hee, my investigation found that Lee Dong-woo was not at school all day on Thursday, but took leave to return to his hometown in Jeolla Province.

Then I called to inquire that the neighbors of Lee Dong-woo's hometown had indeed seen Lee Dong-woo himself on Thursday.

I also secretly checked Lee Dong-woo's dash cam, and he did return to his hometown in Jeolla Province on Thursday. He was returning to Seoul on Friday morning. ”

After listening, Kim Yunhao did not make any evaluation, but explained: "Continue to investigate, you go to Jeolla Province to investigate specifically." I can handle it alone. ”

Hearing Jin Yunhao's order, Yin Guohong smiled: "Received, in fact, I don't need you to explain, I also plan to investigate it myself." I'm on my way to Jeolla-do right now.

Kim Jixi, actually, I just thought about it. The murderer framed Investigator Shin Donghae. The purpose doesn't seem to be as simple as it seems. You're going to have to be careful. ”

Kim Yunho smiled indifferently: "I expected this." Okay, that's it, I'll be notified when there's news. ”

Hanging up the phone, Kim Yun-ho showed an excited look for the second time.

The more carefully this case is designed, the more it proves that the murderer is powerful. With such a powerful opponent, every cell in Kim Yunhao's body is jumping with joy.

It's been a long time since he's experienced the feeling of racking his brains to solve a crime.

The scene of the crime was arranged by the murderer without any flaws, and there were no clues in the time of the crime, and the motive for the crime was impossible to talk about.

So set up. It really looks flawless.

But Kim Yunhao knows that the more seemingly impossible the crime, the more suspicious points will be, but now these suspicions are all well covered up by the murderer.

Now his job is to lift the covers.

First of all, the target he aims at is 'crime time'.

It is an ironclad fact that the killer appeared at the scene when Cho Sang-hee and Jang So-young were killed on Thursday night. He must have entered the building and left the building after the incident.

The suspect has not been found yet, because the killer used a trick. The trap was laid out in advance in terms of the time of the crime.

For this kind of time trap, the best thing to do. It is to expand the scope of the investigation.

He had previously investigated the surveillance on Thursday, but now he wants to expand the scope of the investigation, delaying it for 24 hours from Wednesday.

If he doesn't find it again, he continues to expand the scope until he finds something suspicious.

This method is stupid, but it is the most real and effective.

Kim Yun-ho used his second-seat identity to call in investigators from other prosecutor groups to help him view the surveillance footage.

Four groups of eight investigators, plus Kim Yun-ho and Song Eun-ji, a total of ten people, spent nearly two hours checking the surveillance on Wednesday and Friday, and finally found suspicious points.

"Jin Cixi, look here, isn't this teacher Li Dongyu who entered the apartment building?" Song Eunzhi pointed to the characters that appeared on the screen and said.

Kim Yun-ho glanced at it and confirmed that it was Lee Dong-woo. Then he glanced at the time on the screen: 6:15 p.m. on Wednesday.

He didn't say a word, and immediately fast-forwarded the video, and a minute later, he saw the picture of Lee Dong-woo leaving, and the time was 7:05 on Wednesday night.

But this picture is not very clear, and you can't see Lee Dongwoo's facial features, and you can only judge that he is Lee Dongwoo from the clothes of the characters in the picture and the same briefcase in his hand.

Kim Yun-ho immediately picked up his coat and commanded, "You continue to investigate and notify me if you have new discoveries." ”

After speaking, he put on his coat and immediately rushed to Zhao Shangxi's house.

――

When I arrived at Zhao Shangxi's house, it was already noon.

In the house, Li Dongyu, Zhao Dongmin, and Li Huina were eating lunch.

Seeing Kim Yun-ho arrive, Lee Dong-woo stood up and asked, "Kim Ji-xi, you haven't eaten yet, do you want to be together?" ”

Lee Hina hurriedly brought an unopened takeaway, but Kim Yunho didn't answer it, and he walked straight into Cho Dongmin's room.

On the desk, he found Zhao Dongmin's previous painting books and looked through them one by one.

These pictures record fragments of Zhao Dongmin's life.

There are pictures of living at home, and there are pictures of studying at school.

Kim Yun-ho noticed that Cho Dongmin's paintings had appeared many times in the picture of Mr. Lee Dong-woo. But without exception, Zhao Dongmin did not draw Lee Dongwoo's facial features in detail, only a rough outline.

Kim Yoon-ho also analyzed the environment in the painting, and this person is Lee Dong-woo.

In order to further verify his conjecture, Kim Yunhao came to the living room and sat next to Zhao Dongmin and asked:

"Zhao Dongmin, don't you like Teacher Li Dongyu very much? Why haven't you ever drawn Mr. Lee Dong Woo in your paintings? ”

Zhao Dongmin looked up at Kim Yunhao with a puzzled expression: "I love... I painted! ”

After speaking, Zhao Dongmin seemed to be a little excited, snatched the painting book in Kim Yunhao's hand, and then turned to a picture that Kim Yunhao had seen before, "I painted!" He is! I painted! ”

"I'm sorry, I didn't see it." Kim Yun-ho apologized: "But why did you only draw his outline?" Your level of drawing is very high, why don't you draw facial features for Mr. Li Dongyu? ”

Everyone is his own talent, and Zhao Dongmin's talent is painting, although he suffers from intellectual disability, it has not affected his talent for painting.

Although Zhao Dongmin's paintings do not reach the professional level, the characters are painted vividly, and it is easy to see who he paints.

Zhao Dongmin's paintings of other people are very vivid, and the facial features are very obvious, but when he painted Lee Dong-woo, he did not have any facial features, and only drew the outline. This made Kim Yunhao suspicious.

Hearing Kim Yun-ho's apology, Zhao Dongmin calmed down a lot, lowered his head and continued to eat, and whispered: "The teacher won't let me, only allow me to draw his outline." ”

Only outlines?

Hearing this, Kim Yun-ho's eyes flashed, and he immediately took out the painting book in Zhao Dongmin's backpack and looked through the pictures he drew last night.

In these drawings, the fourth person who appears at the scene also has only one silhouette and no close-up of his face.

It stands to reason that Zhao Dongmin's painting level is good, and he should be able to draw a close-up of this person's face. But he didn't!

Now, Kim Yun-ho still has one last doubt in his heart.

He pointed to a picture and asked Zhao Dongmin: "Who is this person who is standing on the podium and giving a lecture, only the outline?" I can't see it clearly. ”

Zhao Dongmin raised his head and looked at the picture, then looked at Li Dongyu, and did not speak. But his expression already reveals the identity of the person in the picture.

Kim Yun-ho looked at Lee Dong-woo and ordered solemnly and compulsively: "Teacher Lee Dong-woo, please point to this picture, ask Zhao Dongmin the same question, and ask him who the person in the picture is." ”

Li Dongyu smiled faintly, looked at Jin Yunhao meaninglessly, and said slowly: "Zhao Dongmin, who is this person in the picture?" ”

Seeing Li Dongyu asking, Zhao Dongmin spoke: "Yes... Uncle Investigator. ”

Zhao Dongmin actually called Li Dongyu in the picture 'Uncle Investigator'!

"Oh Mo!" Li Huina, who had been secretly watching, heard it, covered her mouth and exclaimed in a low voice.

And Kim Yun-ho immediately stood up, came to Li Dongyu's side with a stride, and said in a deep voice: "Presumably, it was you who taught Zhao Dongmin to answer like this." ”

Li Dongyu still had a faint smile, not in a hurry or in a hurry: "Hehe, I don't know what you're talking about?" ”

Kim Yunhao said: "It doesn't matter if you don't know, I'll tell you one by one."

Under your inducement, Zhao Dongmin drew the scene of the crime on Thursday night, but that person was not the 'investigator' uncle, but you.

It was you who taught Zhao Dongmin to say this before, calling you the 'investigator' uncle in the painting. So as to blame Shen Donghai. ”

Li Dongyu pursed his lips with an indifferent expression: "What does this mean?" Zhao Dongmin was already suffering from severe intellectual retardation, and his words could not be trusted at all. Maybe he's talking gibberish and confusing me with Shin Donghae. ”

Kim Yun-ho did not continue to argue with Lee Dong-woo and continued:

"I checked Wednesday's surveillance footage and found that you were here on Wednesday night, but when you went out, the picture was not clear, and you could only see the outline. You're not the one I want to go out, are you?

Where are you from Wednesday night to Thursday night? ”

Lee Dong-woo smiled confidently, "I drove back to my hometown in Jeolla Province on Wednesday night, spent the night there on Thursday, and returned to Seoul on Friday morning. If you don't believe me, ask the local residents of Jeolla-do.

Oh yes, it also shows on my dashcam.

Pretty surprising to you, right?

I have a good alibi. ”

Lee Dong-woo looked at Kim Yun-ho playfully, looking calm.

Kim Yoon-ho also knows that this alibi is the key, and if he solves this problem, he will not be able to debunk Lee Dong-woo at all.

But at this time, Yoon Guohong called, and after answering the phone, Kim Yunhao looked at Li Dongyu with a deep gaze and said with a smile:

"I'm sorry to inform you: your alibi was debunked by my assistant investigator ......" (To be continued......)
