Mo Wenya had already taken the body for a CT scan, and the CT scan found that two parts of Gong Chenggong's brain were in an abnormal state of excitement, one was the auditory center and the other was the pain center. The pain center also controls the negative emotions of human beings such as sadness, frustration, and depression, which confirms Qin Kai's conjecture that the murder weapon will indeed make people experience great mental pain, which cannot be alleviated without suicide.

Qin Kai nodded, and the complicated clues were gradually sorted out by him, and he said to Mo Wenya: "You send me a copy of all the autopsy data in the past few days, I want to study it carefully." ”

"What are you doing studying the autopsy data?" Mo Wenya didn't understand what Qin Kai wanted to do, and said, "Shang Tieniu, Zhang Yao, Deputy Director Gu, and Gong Chenggong, the cause of their death is determined, there is nothing to study." ”

"Not necessarily, you are investigating the cause of their death, so have they had the same disease before?" Qin Kai asked, "This disease may not be the fatal cause of death, but it is what several of them have in common." ”

"What do you mean?" As soon as Xia Hongyun heard this, she knew that Qin Kai must have made a discovery, and her spirits lifted and she asked.

Qin Kai gave Xia Hongyun the information at hand and said: "Before, I always felt that there were some details that we had omitted, until I heard Lin Tinghua say that Deputy Director Gu fell in love with a lady sitting on the stage more than ten years ago, and finally, under the pressure of reality, Deputy Director Gu broke up with the lady sitting on the stage. This incident also dealt a big blow to Deputy Director Gu, not only affecting his reputation, but also preventing him from being promoted for more than ten years. ”

Xia Hongyun nodded and said, "I've also heard about this matter, but what does this have to do with Deputy Director Gu's death?"

Qin Kai said: "The four deceased do not have much intersection, except for the case of Ying Feifei, they did not participate in the criminal case together. But there is one thing that is very closely related to the four people, and that is the lady who sits on the stage. I checked the records of this young lady sitting on the stage, he had activities in the jurisdiction of Shang Tieniu, Zhang Yao and Gong Chenggong, and later, she fell in love with Deputy Director Gu, so she didn't do these things. ”

Xia Hongyun pondered for a while and said: "But if people don't know unless they do it, Miss Zatai has a criminal record, and Shang Tieniu, Zhang Yao and Gong Chenggong must all know her." Therefore, when the three of them saw her, they all pointed out that she was a lady sitting on the stage, which embarrassed Deputy Director Gu, and she couldn't get off the stage, which also became a joke in the bureau. ”

Qin Kai said: "The idea is right, but things are not so simple. I checked the promotion path of Shang Tieniu, Zhang Yao and Gong Chenggong, and the three of them were suddenly promoted and reused by the city bureau at that time. At that time, Deputy Director Gu was already the deputy director of the Municipal Bureau, and he happened to be in charge of personnel and criminal investigation. ”

Xia Hongyun's face changed, and she exclaimed: "You mean to say that the three of them threatened Deputy Director Gu." And Deputy Director Gu was under pressure and could only comply with the three of them. ”

Qin Kai nodded and said, "Later, Deputy Director Gu couldn't bear the pressure, so he first broke up with Miss Sitting, and then took the initiative to confess the matter to the bureau leaders. Since this is a dispute of personal feelings, it cannot prove that Deputy Director Gu abused his power, and the bureau only symbolically punished Deputy Director Gu and did not remove him from his post. ”

"Wouldn't you know if you went to check?" Qin Kai said, "One thing I'm curious about, what happened to the final fate of that young lady sitting on the stage?"

Xia Hongyun said: "I know a little bit about this matter, I heard that after the lady sitting on the stage broke up with Deputy Director Gu, she was hurt physically and mentally. I also heard that she killed a child for Deputy Director Gu. I thought that I would grow old with Deputy Director Gu, but I didn't expect the two to part ways. Later, she got a serious job and wanted to start over. Unexpectedly, after getting off work one night, she was indecent to three hooligans and finally committed suicide. ”

"Did Miss Sitting on the Stage kill herself?" Qin Kai's face changed, and he exclaimed, "It's not good, his next target is those three hooligans!"

Xia Hongyun hurriedly took out her mobile phone and dialed the person in charge of the information center, asking him to find three people immediately.

Soon, there was a reply from the information center, and the addresses of the three people had been found.

Xia Hongyun and Qin Kai were about to lead the team out, when a policeman ran in and shouted in a panic: "Team Xia, it's not good, there is a major criminal case." ”

"What's going on?" Xia Hongyun asked with a frown.

The policeman said: "We received a report that several people died in the Banyuan Community on Taoyuan Road, and we don't know if it was suicide or homicide, and the bureau leader asked the task force to take over the case." ”

"What did you say?" Xia Hongyun asked in surprise.

The policeman was stunned and said, "The bureau leader asked your task force to take over this case, Captain Xia, is there any problem?"

"No, in the previous sentence, where did the person who was killed live?" Xia Hongyun felt faintly uneasy.

The policeman said: "The deceased lived in the Banyuan Community on Taoyuan Road, Xia Team, is there anything wrong with this?

Xia Hongyun said angrily: "Damn, it shouldn't be the three of them bastards!"

Qin Kai and Xia Hongyun immediately set out and came to the Banyuan Community on Taoyuan Road, and they prayed in their hearts, hoping that it was not those three bastards who died.

There are a lot of people watching the excitement downstairs, as well as some sad and weeping family members, and the police in the jurisdiction are trying their best to maintain order.

Qin Kai and Xia Hongyun pushed through the crowd and walked in, took the elevator up to the seventh floor, and saw that the three doors were open, and the corpses of men, women and children in the room were lying in different places.

Judging from their methods, these people should have died by suicide. Some swallowed nails, pierced their eyes with knives, hanged themselves, and cut their throats.

Xia Hongyun was dumbfounded, the one who died was really the family of the three hooligans more than ten years ago, but this time, the murderer was very ruthless, and none of the three families were spared.

"What a ruthless heart!" Xia Hongyun was furious, this murderer was too blind, walking in front of them every step, as if they were thinking, the murderer was clear, and forcibly cut off the clues they had worked so hard to find.

Qin Kai didn't say anything, but carefully inspected the scene of the crime. Mo Wenya came over and began to perform an autopsy on the corpse.

Mo Wenya said to Qin Kai: "I sent someone to send Zhang Minzhi back, she will follow Zhang Minzhi to protect her, don't worry!"

Qin Kai nodded and said, "Thank you!" and went out of the scene of the crime, standing in the corridor and smoking.

Xia Hongyun followed, the case was weird, and she wanted to hear Qin Kai's opinions and opinions.

This murder scene is very special, the murderer was standing in the corridor to kill someone, but the police didn't know, the corridor was trampled on, footprints or anything could not be found, Qin Kai thought about it, and said to Xia Hongyun: "There should be monitoring in the elevator and at the entrance of the community, right? Let's go to the property to have a look." ”
