At around 7 o'clock in the morning, Su Cheng was watching the interrogation process outside the interrogation room. The seven-group interrogation room has been renovated, and there is an independent small room here, where you can see the interrogation situation clearly through the glass. The glass cannot be seen in the interrogation room, and this thing is also called a double-sided mirror. Roadside club reported that in some hotels and bathrooms, there are usually mirrors, and some mirrors touch the surface with their fingers. If there is no distance, the two fingers are touching each other, which means they are double-sided mirrors. Some people are peeping at you. Some are smart, installing the camera behind the mirror, installing only one position, and it is difficult to try it out with their fingers.

The world is dangerous, and when you go out, especially girls, you should be more careful.

Xu Xuan handed Su Cheng a cup of coffee, and Su Cheng took it over: "Thank you."

"You're welcome." Xu Xuan also took a cup of coffee and sat on a high chair with Su Cheng to watch the interrogation. This time she cooperated with Su Cheng, and Xu Xuan was quite accomplished. Xie Yu's arrest can be said to have more than 50% of the credit.

But the interrogation result surprised everyone. Yes, this friend Xie Yu did kill the first deceased Xiaoyu, and the process was similar to Xu Xuan's guess. Xie Yu had known Li Rui's hobbies. When he learned that his girlfriend was unwritten, he forgave his girlfriend, sneaked into Li Rui's office, and wanted to delete the video. But after watching the video, jealousy and anger were picked up. He left Li Rui's office, looked at the video downloaded to his mobile phone, and found the other side of his girlfriend. He became more angry and could not forgive Xiaoyu, so he decided to kill Xiaoyu.

The second deceased, Lin Yan and the two of them were downloaded by Xie Yu. After Xiaoyu's death, Xie Yu threatened to use screenshots to make an appointment with the second deceased and killed the deceased. His revenge for Xiaoyu did not end because of Xiaoyu's death, but was a little unsatisfied. The second deceased was his replacement for Xiaoyu. He tried to talk to the unconscious victim, but found that he still couldn't control his anger, so he killed it as Xiaoyu.

It is normal to confess here, but Xie Yu denied killing Lin Yan. Xie Yu said that he was kidnapping the second deceased and said everything he didn't say to Xiaoyu. After killing the second deceased, he felt that everything was over, so he did not intend to kidnap others again.

Su Cheng and others believed in Xie Yu's confession. The bald head of the second group also confirmed from a psychological perspective that Xie Yu was unlikely to kill Lin Yan, and Xie Yu might not lie. Zuo Luo asked the physical evidence group to work overtime. The physical evidence group concluded in the afternoon that although they were all wooden strips and all packaging ropes, the material structure of the first and second deceased was the same. The ropes that tied Lin Yan and the material structure of the wooden strips were different. At the same time, news came from the criminal police team that objective evidence also confirmed that when Lin Yan died, Xie Yu had evidence of absence. He went to Linyuan County on a business trip.

That means there is another murderer who borrowed Xie Yu's case handling model and killed Lin Yan. The murderer knew the existence of the video.

At this time, the forensic identification resulted. Unlike the first two cases, Lin Yan showed signs of being violently attacked, while the first two deceased were all controlled by the murderer after being drugged. Preliminary speculation was that Lin Yan had entangled with the other party, and the other party finally used narcotics to cover Lin Yan's mouth and nose, causing him to fall into a coma. The crime mode was different.

Su Cheng said: "I personally speculate that the murderer wanted to use video to blackmail Lin Yan, but something went wrong. He killed Lin Yan according to the pattern of the first two cases."

Zuo Luo said in a deep voice: "But, only Xie Yu and the police know the details of the case."

Song Kai said: "It's not all about it. After the second case, there were rumors on the Internet, and the scene was very close to the scene of the crime. However, the details were insufficient, and the tied ropes were tied together. Lin Yan's wedding dress was different from the first two deceased, and it was not the stolen wedding dress." The physical evidence group had preconceived ideas and thought it was a serial killing. After Xie Yu confessed, he carefully inspected the physical evidence of Lin Yan's case.

Zuo Luo said: "That is to say, this person knows something, but he doesn't know the details."

"Yes." Su Cheng agreed.

Zuo Luo said: "But he has Lin Yan's video."

Su Chengshen exclaimed: "There are some cases that need to be investigated." The more criminals commit crimes, the more likely they are to be exposed. On the contrary, if there is only one case, it is relatively difficult to start. And it is easy to be confused by the previous cases.

When I knew that there was a second murderer in the serial murder case, the forensic and physical evidence teams were all busy, and the seventh teams were also busy. They started to check the clues at the meeting, separate the clues, and change their thinking. They were busy until eleven o'clock in the evening, and had no clues. They could only temporarily keep an eye on Qin Shimingyue Company. After all, only the company's personnel are most likely to get videos.

The bureau also called and signaled that the case was temporarily handed over to the criminal police team. Because of the non-serial murder case, Group 7 is not responsible for investigation. There is another reason to hand it over to the criminal police team. Group 7 needs to assist a group to fight against prodigal intermediaries.

After the man in black was arrested, a group obtained some information from the prodigal intermediaries. The transaction information between the man in black and Zuo Luo was only a small part, indicating that twelve prodigal intermediaries received training from Tangling, and are currently lurking in City A as a business expansion staff of Tangling. However, several of them were very loyal and not very cultivated. Tangling decided to sacrifice them and hand over their information to Zuo Luo as a condition of exchange.

These five people have been temporarily detained and the bureau has no interest in them because they are abandoned children and are not in the Gantian plan, and they have no criminal facts. How to use the resources of the five people to find another seven prodigal intermediaries trained by Gantian is what is interesting to the bureau. As long as these seven people are caught, it is impossible for the Gantian to log in to City A in the short term.

At 11 o'clock in the evening, someone from the criminal police team began to hand over the Lin Yan case. Xu Xuan took the car key and said to Su Cheng: "I'll take you back."

"Thank you." Su Cheng was not polite either.

...

Su Cheng and Xu Xuan arrived downstairs of the apartment. Su Cheng opened the car door and hesitated for a while: "Can you go up and have a cup of tea?"

Xu Xuan was confused: "Su Cheng, what's the situation?" Why did the mother-in-law and mother do?

Su Cheng said sadly: "I don't want to stay alone in the apartment... There are many wonderful memories of Philona and me."

"That's why you work overtime, but you don't want to go home." Xu Xuan looked at Su Cheng for a while: "Let's do this, I'll ask Zuo Luo to change your place tomorrow."

"today?"

You can't even get through today? Since Su Cheng spoke and was like an injured puppy, Xu Xuan said helplessly: "You go to my dormitory living room first and will you only have one night?"

Su Cheng was overjoyed and closed the car door: "Thank you."

Xu Xuan drove and said for a while: "I didn't expect you to have a sentimental side too."

Su Cheng asked: "Do you think I should be?"

"Behind the gentle appearance is ruthless, desireless, cold, indifferent, cruel..."

Su Cheng pressed the rearview mirror to look at himself: "I didn't find myself having such characteristics."

Xu Xuan said: "A mouse is publicly mixed into the cat's team. Do you think this mouse is a kind person?"

Su Cheng spread his hands: "Maybe I am a rat gangster."
