Kim Yoon-ho finally accepted Han Zixin.

Not only because Han Zixin has a good attitude of admitting mistakes, but the most important thing is that Kim Yunhao values Han Zixin's good psychological quality.

The most private secret is overheard, but you can adjust your mentality in a short period of time and face it calmly, which is not something that ordinary women can do.

With such a good mindset, the potential is huge.

This is what Kim Yoon-ho values.

Of course, Han Zixin's return to nature was inevitably embarrassed by the hippos, who gave people nicknames when she was mad.

Now, retribution has come.

In order to calm everyone's anger, Han Zixin specially gave everyone the warm treasure she bought before. Subsequently, he took the initiative to undertake the duty work at night after work, and monitored Li Dongyu with the elephant.

In this way, the matter can finally be settled.

――

In the second half of the night, Kim Yun-ho had been thinking about the ghost murder case, and when he was sleepy, he ushered in a group of guests, who were Yoon Kook-hong and Park Ji-tian.

After getting into the car, Yin Guohong rubbed his frozen hands and began to report to work:

"Kim Ji-shou, our investigation has a result.

I went to the nearby police station to investigate, and in the recent period, the same police officers have been to the incident building several times, without exception!

So I would venture to speculate that the theft of the doorknob of the building, the presence of a large number of rats in the building, and the false report by the security guard were all related to this case. ”

Kim Yoon-ho had expected these things a long time ago, and Yoon Kook-hong's investigation only proved his guesses.

"That's all?" Kim Yoon-ho asked rhetorically.

Yin Guohong replied with excitement on his face: "Also, I found out a very important news from the police.

There was a man who once inquired about the police on duty. And this person is still our old acquaintance - the fake Li Dongyu. Li Tianyu! ”

Kim Yoon-ho came interested. Leaning forward, he asked:

"Li Tianyu? In the first secret room case, the person who was suspected of helping Lee Dong-woo make an alibi?! ”

Yin Guohong smiled and nodded: "Yes, it's him!" In addition, I also found out the identity of this Li Tianyu, he is a bricklayer and worked in the building where the incident occurred. ”

bricklayers, working in the building where the incident occurred, and inquiring about the duty at the police station......

After connecting these messages together, the truth immediately comes to the surface.

"He's probably the real murderer of the Ghost Quest!"

Yin Guohong finally concluded. The excitement could not be concealed.

Kim Yun-ho nodded, agreeing with him.

But then he thought of something else.

Kim Yun-ho immediately found a photo of Lee Tian-woo and a video of his trial, beckoned to Kwon Jeong-seon, who was in the back row, and ordered:

"Let's see, this person is the suspicious person we're looking for!"

Kwon Jeong-sun dodged in order to avoid suspicion, and when he heard the order, he moved over.

After careful comparison, he gave the answer: "It's very similar!" 60%！ It is very likely that the package was handed over to the target by this Li Tianyu. ”

The suspicious person was found, but then a new question arose - what was inside the package?

Kim Yun-ho thought about it for a long time and didn't have a clue.

If you can't think of it, you don't want to think about it for the He turned his attention back to the ghost murder case.

"Tell me, what else did you find?" He asked.

"That's what I've looked into here." Yin Guohong finished speaking. looked at Park Zhitian beside him.

It was the first time for Park Ji-cheon to report to Kim Yoon-ho as a subordinate, and he was a little nervous, and the report was also very formal.

"Team leader Yin Guohong is investigating the suspect in the case, while I am investigating the details of the case.

After learning about the case, I always had a question: why did the two investigations in the same room turn out to be completely different? How do corpses disappear out of thin air, and then appear out of thin air?

When I went to the restaurant in the evening, I went to the wrong room because the box layout was the same. That's when I got inspired.

I envisioned that the rooms on the 18th floor of the building were exactly the same, and that it was possible that the security guards and the police would not investigate one room at all, but two rooms.

Looking back at the whole case, I found a clue: the security guard's confession was not detailed.

In their confessions, they did not elaborate on how they determined the target room, as if they naturally assumed that the same room was the same for the two investigations.

Later, I questioned the security guards again, and they said that there was a mousetrap at the door of the target room, and they judged the target room based on this.

However, the trap is movable! After committing the crime, the murderer can take advantage of the fact that no one is there to move the mousetrap to create a false impression and mislead the security guards and police to go to the wrong room.

Moreover, the investigation results of Team Leader Yin Guohong show that the rat incident in the building may be related to the murderer.

So after a comprehensive analysis, I speculate that the security guards and the police investigated two rooms before and after. In this way, the suspicion that 'the corpse disappeared out of thin air and appeared out of thin air' can be explained! ”

"Bang Bang Bang"

After listening to Park Ji-tian's investigation and analysis, Kim Yun-ho applauded, his eyes full of appreciation.

"The speculation is well-founded and perfect."

After receiving the appreciation, Park Zhitian did not get carried away, he pulled his hair and said:

"However, I still have a question that I can't figure out. The two security guards insisted that the murderer they saw at that time was Li Dongyu. However, Li Dongyu was being detained in a detention center at the time of the crime. It simply doesn't make sense. ”

Kim Yunho smiled confidently and said, "This question is not difficult to explain.

Li Dongyu and Li Tianyu are somewhat similar, and if Li Tianyu deliberately imitates Li Dongyu's expression of committing the crime, then it is not surprising that the security guard is wrong. ”

Seeing the same puzzled expressions of Park Zhitian and Yoon Guohong, Kim Yunhao patiently explained:

This question involves preconceived mental implication knowledge.

Before the case, Li Dongyu's case was hot, and he himself frequently appeared in the report.

And the security guards have a lot of time and will often watch TV, so they can naturally see these reports and have a certain impression of Lee Dong-woo.

In this way, they will leave a face and an idea in their subconscious: Lee Dong-woo may have killed people, he is a bad person.

At the time of the crime, they saw someone who looked a little like Lee Dong-woo again. Then the subconscious meaning of the previous will automatically appear. Replace some of their memories at the time.

In the end, it was caused. The appearance of the murderer they depicted based on their memories became the real Lee Dong-woo.

When I was studying in the United States, I came across a similar case where the FBI mistakenly arrested a suspect based on an eyewitness account. In the end, it was the psychologist who helped the FBI explain this bizarre mental phenomenon. ”

After listening to Kim Yunhao's popular science, Park Zhitian and Yoon Guohong suddenly realized.

It turned out to involve mental knowledge, no wonder the two of them couldn't figure it out.

After being silent for a while, Yin Guohong suddenly slapped his thigh and said, "No, this case seems to be committed by Li Tianyu alone, but this case must be related to Li Dongyu!"

Li Tianyu took so much pains. even used psychology to create the illusion that Lee Dong-woo was the murderer, and they must have a deeper purpose. ”

"Not bad." Jin Yunhao nodded and said: "The two high-IQ secret room murder cases are all fakes, and there must be a deeper and greater purpose hidden behind them. ”

"You found a clue?" Yin Guohong asked expectantly.

It's a pity that Kim Yunhao shook his head: "No." But this time we are no longer confused, and we can even say that we have the initiative.

We know that they have a certain purpose in committing crimes, but they do not know about us, let alone the existence of the Surveillance Section.

That's our advantage. This time, be sure to take them down! ”

After giving Yoon Guohong and Park Zhitian enough confidence. Kim Yun-ho instructed: "I'm monitoring Lee Dong-woo on this side, and you guys are going to spy on Lee Tian-woo." Prevent it from escaping. Tomorrow, wait for my order to arrest Li Tianyu in public. ”

Yin Guohong asked rhetorically: "It's not a problem to arrest him, Shen Donghai has already brought people to monitor him, and he can't escape." But are you trying to scare the snake? ”

Kim Yunho replied categorically: "Yes, I want to see... Is there anyone who is deeper in this? ”

Yin Guohong was surprised: "Deeper people? You mean...... Mystery Man X?! ”

"Not bad."

"But now except for Shuangli and the others, there is no one else. Perhaps, Li Tianyu is the mysterious person X? ”

Kim Yunho explained: "Normal analysis, there is such a possibility. But I have a feeling that he's not X.

The case of Liu Renna's sisters, two cases of murder in a closed room, and three cases were all high-IQ crimes. It even involves the knowledge of psychology.

It is difficult for ordinary people to design such a difficult case.

And these are only superficial things, and we don't know their deeper purpose yet.

Therefore, the mastermind behind the scenes must be a person with a high IQ and a high degree of education, and obviously the situation of Li Tianyu, who has a low education, does not conform to this speculation.

So I suspect there's another person behind this. ”

――

Yoon Kook-hong and Park Ji-cheon left with the latest instructions, they were going to spy on Li Tianyu, arrest Li Tianyu on the spot tomorrow, and investigate the last question: the identity of the deceased.

It's a lot of work.

And in the command car, Kim Yunhao did not rest, he was thinking about the case and the means to solve the case.

Now that the case has been clarified, there is no evidence.

Kim Yun-ho knew very well in his heart that according to X's IQ, the evidence of the ghost case must be destroyed.

According to the current information and the repeated testimony of eyewitnesses, Li Tianyu can only be suspected, but it is very difficult to convict Li Tianyu.

This case, like the first murder in a closed room, can only be started from other aspects. This is where the ability of the case handler is tested the most.

Fortunately, this time Kim Yunhao has an extra hole card in his hand - the Surveillance Department.

The Surveillance Section had just been established, and the other party had no idea of its existence. This is Kim Yoon-ho's greatest confidence in solving the case.

At present, Kim Yoon-ho and the Surveillance Section have a total of three issues in front of them.

What exactly was in that package that Lee Dong-woo received.

Will Lee Dong-woo still have contact with other people, and whether other people are hidden behind it.

What is the real purpose of their successive crimes? (To be continued......)
