Zhao Hao cannot tell for the time being whether Zhou Tao’s actions are from the heart or pretending to be angry.

Zhao Hao sorted out the confessions of the four people:

He Meng said that Zhou Tao and the deceased were good friends, Tan Jia said that He Meng had a relationship with the deceased, and Fang Tong said that Zhou Tao had conflicts with the deceased, but Zhou Tao firmly denied that he had conflicts with the deceased.

The conflict point now lies in the relationship between Zhou Tao and the deceased as Fang Tong and He Meng.

Generally, during interrogation, Zhao Hao can judge whether the person is lying based on the micro-expression of the person being tried, but this skill cannot be seen through everyone.

Some people with good psychological qualities can control their micro-expressions. They can express themselves as facial paralysis, and no matter what they say, they are as expressions. It is difficult to see what their micro-expressions mean.

Just now, Fang Tong was facial paralysis when he talked to Tan Jia, and his heart was not at all twists and turns, and his expression did not change at all. Because He Meng always cried, his expression was frowning throughout the whole process, and he could not see other expressions. Zhou Tao was involved in his reputation when answering questions, so he was angry, which also hid his micro-expression.

Liao Zhiguo sat next to him and recorded all the questions answered by the person being tried just now.

Don’t underestimate this simple record. When dealing with the case before, the Crime Team will summarize all the problems in the form of squares, and then use the form of drawing lines to mark the connection between each problem. When there is a contradiction, it is their breakthrough point. Because there is a contradiction, it means that someone is lying, and the lying person is often the most suspicious.

Now, the Crime Team puts the breakthrough of this case on Zhou Tao. If Zhou Tao does sleep with Wang Fan’s girlfriend, then Zhou Tao may have some conflicts with Wang Fan, and thus has a motive for murder.

After releasing the four people, Zhao Hao called the other members of the Crime Team to the office for a brief meeting.

"Now, we focus this case on Zhou Tao, a colleague of the deceased. We want to investigate the relationship between him and the deceased and whether he has an affair with Wang Fan's girlfriend."

Liao Zhiguo expressed a question: "Why is only Fang Tong saying that Zhou Tao and Wang Fan's girlfriend had an affair, while the other two had never said it. Should we investigate the relationship between Fang Tong and Zhou Tao? If they had had conflicts before, then the truth of what Fang Tong said remains to be verified."

Zhao Hao nodded.

Liao Zhiguo’s question is not unreasonable. Since the confessions of the four people are in conflict, at least one of them is lying. If the lying person is arrested, then the case can make significant progress.

"Okay. Now we will divide it into two groups. Liu Tianqi and I are responsible for investigating the relationship between Zhou Tao and Wang Fan's girlfriend. Liao Zhiguo and Huang Ke are responsible for investigating the relationship between Fang Tong and Zhou Tao. Jiaxin is still dealing with Wang Fan's body, so she does not participate in the investigation."

Zhao Hao finished the meeting after saying that.

In the afternoon, Zhou Jiaxin sent an anatomy report.

The deceased died of acute poisoning, and the solution in the paper cup was a fatal source.

This is undoubtedly good news for Zhao Hao. If the deceased dies from acute poisoning, the case will be much simpler. There is no need to consider the people the deceased has come into contact with within a year, but only consider the recent interpersonal relationships.

If you want to know their relationships, the best way to investigate is to learn from the same company's population.

It is most appropriate to leave this matter to Huang because he is born with a social expert. He can find common language with all kinds of people, so he is responsible for every investigation.

Liu Tianqi is a technical stream, and he can still collect the information he wants without going out. He only needs a computer to complete this.

"What are you going to do?" Zhao Hao stood behind Liu Tianqi and watched his hands keep typing on the keyboard, while the computer screen he was manipulating was full of data codes jumping.

"I need to enter the backstage of their company first and find out all the information about Zhou Tao and the deceased. Look here..." Liu Tianqi pointed at the computer screen. Zhao Hao followed his fingers and found that Liu Tianqi had entered the backstage center of the company's employee management through the company's administrator user. All the personal information of the company's everyone is clear.

"Now I immediately log in to mainstream social software on the market with the mobile number of the deceased, and then find the people he has contacted for a long time. After I find it, I will restore their chat history. Maybe we can find the relationship between Zhou Tao, the deceased, and the deceased's girlfriend."

Zhao Hao accompanied Liu Tianqi to restore the chat records of the deceased and his long-term contacts. In fact, this was not simple. Liu Tianqi also asked other members of their hacker organization for help in the middle. It was not until 11 o'clock in the evening that all chat records were basically restored.

Liu Tianqi printed these chat records on paper, and then sorted them regularly before handing them to Zhao Hao's desk.

"Uncle Zhao, the chat records have been restored." Liu Tianqi entered the door and found that Zhao Hao was asleep on the desk, so she whispered.

Zhao Hao rubbed his eyes, "Why did I fall asleep suddenly? It's 11 o'clock. I've been sleeping so long this time."

"Brother Liao and Brother Huang have been back once. They didn't disturb you when they saw you sleeping soundly. This is the clue they brought back." Liu Tianqi handed a folder under his armpit to Zhao Hao.

"You go home and rest, it's already so late. Thank you for your hard work."

"It's okay, I'll sleep in the office tonight. The murder is still at large, how can I rest?"

Zhao Hao smiled with relief, "I'm very happy that you have this kind of awareness. It seems that my decision to introduce you to the Crime Team back then was correct."

Liu Tianqi smiled slightly in response, and then he left Zhao Hao's office.

Both documents seem to be quite large, and Zhao Hao first read the information brought back by Liao Zhiguo and Huang Ke.

Liao Zhiguo and Huang were responsible for going to the deceased's company to investigate the relationship between Fang Tong and Zhou Tao. According to the report they brought back, Zhou Tao and Fang Tong did not have much intersection. Although they were in the same department, the things they were responsible for were different, so they had no contact in normal times. It was basically ruled out that Fang Tong and Zhou Tao had conflicts, so they deliberately fabricated Zhou Tao to sleep with the deceased's girlfriend.

Liu Tianqi investigated the relationship between Zhou Tao and the deceased's girlfriend.

Judging from Zhou Tao’s social software friends list, 90% of his friends are women. 70% of them are women aged 18-25, and the rest are female students who are underage.

The deceased's girlfriend is Xuan Caixia. She has just graduated from college for one year and is now internship at an advertising design company. What's interesting is that the company where Xuan Caixia internship is on the same floor as the deceased.
