The two returned to the research and judgment conference room. Without Qu Hou's instructions, Xu Zheng sent the record of the inquiry to the notebook in front of everyone, and at the same time briefly stated his judgment.

Qu Hou nodded, "I agree with Xu Zheng's idea. Although the 19-year-old dating website has been closed, you can still find screenshots of chats on the website at that time. It shows that the chat dialog box only has avatars. If a person registers two accounts,

The avatar and information are the same as those of Cai Xiaokun and Su Nanying, and I also know their mobile phone numbers, so I can completely transfer them."

Then everyone discussed who could know Cai Xiaokun's and Cai Xiaokun's mobile phone numbers at the same time, and who knew them well. Qu Hou drew a circle and prepared to send someone to investigate this point later.

At this time, a beautiful policewoman said: "Team Leader Qu, colleagues, I found that these five cases were probably in Ichibashi District and Xuangui District, and the delivery boy who died tragically in an accident was in his delivery

On the way to express delivery, it means that the murderer can often observe him. Does that mean that the area where the murderer lives or works is probably the area where the deliveryman is responsible?"

The bald man who was transferred from the Criminal Police Brigade of Hitotsubashi Branch slapped the table and said, "I also judged this way, and this person must have had conflicts with the delivery person. But I checked the customers who complained about the delivery person before the incident.

No suspicion was found.”

Qu Hou fumbled with his beard and said, "Zhuang Qiang, please check those people again later. Don't make too much noise. It's only been three years. There is a high probability that those people will not move or leave the city. If there are, focus on the investigation."

Zhuang Qiang, a bald man, nodded vigorously, "Don't worry, team leader, I have to find out all three generations of their family this time."

Everyone smiled kindly, and it could be seen that he was very aggrieved because there was insufficient evidence in his hand and the incident was defined as an accident.

At this time, there were two colleagues from the criminal police detachment, who were responsible for the crime six years ago. They said: "The murder we were responsible for, the murderer's murder was so seamless. If it wasn't a coincidence, I guess it wouldn't have happened."

,At present, we still don’t have any clues.”

Xu Zheng turned on the computer and turned to the song he was talking about. Six years ago, in the summer, a community in Changming City opened for business. An aunt who was working as a caretaker was too involved in her job and screamed hoarsely for a long time. As a result, she suffered a heart attack.

He died on the spot. The handling staff combined the case this time because, firstly, the aunt was 54 years old and had just had a physical examination, and all physical indicators were normal; secondly, it was a coincidence that it was her birthday; and thirdly, she had a hair condition.

The water cup that Auntie brought with her was never found at the scene; fourthly, the medical examiner concluded that the cause of Auntie's death was myocardial infarction, the rescue was not timely, and no drug-induced factors were found due to the conditions at the time.

At this time, the beautiful policewoman put forward another concept, "Do you think, besides coincidence, do these girls have something in common?"

Xu Zheng was a little curious about this 30-year-old beautiful policewoman. There was no doubt about her ability to come to this conference room. He secretly asked the bald man on the computer, "Brother Zhuang, who is this beauty?"

"Nanque District, the captain of the criminal police brigade of the branch, Zhang Yuqi, is a woman. There is news that she may be transferred to the detachment this year."

Colleagues are of course very active in asking questions about beautiful women, and they have to say a few words casually if they don’t find anything. No, some people saw that the colleague in front of them had finished saying everything they could say, so they made it up and said: "Well, I think they have something in common."

One thing is unavoidable, that is, the victim and the murderer have a grudge, and the grudge is as deep as the ocean!"

Xu Zheng and the others couldn't hold it back and almost laughed out loud. Isn't it obvious that they would go to such great lengths to plan an accidental murder without revenge?

However, Zhang Yuqi slammed the table hard and spoke eloquently, "I think everyone has fallen into a misunderstanding. Conflict is a possibility, so why can't it be a possibility if there is no contradiction? Maybe the murderer is itchy and feels that this

Can accidentally killing people bring him infinite pleasure?

Maybe there is only a small conflict between them, but if the murderer has an extremely narrow mentality, why can't he take revenge just because of the quarrel?

I think the murderer should be around 40 years old, male, and should have a successful career. He is narrow-minded and has a strong desire for revenge. In reality, he should be a gentle and generous person."

Xu Zheng was dumbfounded. This was psychological profiling. Sure enough, there were things outside the world, and there were people outside the world. He hadn't learned it yet, so he didn't dare to do psychological profiling, otherwise it would be extremely easy to mislead himself.

At this time, Qu Hou looked at Zhang Yuqi and smiled with satisfaction, and even took the lead in applauding, "I think Captain Yuqi's psychological profile is feasible. This person can pull off accidental murders so smoothly, and he has no control over the police's handling of it."

The method of eucalyptus is very familiar, but the age should not be too young.

Huo Weian, Ji Meiyue, do you two have any clues about the key suspects in charge of Hitotsubashi District and Xuangui District?"

The key suspects Qu Hou mentioned were lawyers, judges and other successful people in society who had some connection with criminal investigations, but these two men stood up, lowered their heads, and looked like they had admitted their mistake.

Qu Hou waved his hand. He had to screen hundreds of people that day. Besides, the effect of ordinary screening would definitely not be great.

Xu Zheng also had an idea at this time, so he raised his hand. When Qu Hou saw it, he laughed and scolded: "You, a primary school student, are answering questions! If you have something to say, say it, and if you have something to say, let it go. Let's discuss it. Who doesn't say whatever he wants?

Are you afraid of being laughed at if you say something wrong?"

Everyone laughed again. When Xu Zheng saw it, Zhuang Qiang laughed the loudest. The few stubborn hairs around his bald forehead were unable to be covered by his smile.

Xu Zheng also smiled when he saw Zhang Yuqi, "Captain Zhang, I have actually only investigated the accidental car accident and the young woman jumping off the building. I think so. The murderer must be very aware of the living habits of the two female victims, and even the investigation on jumping off the building."

Eucalyptus Su Nanying also knows a little about her husband’s work and habits.

Captain Zhang, you are a woman, think about who else knows you well besides your husband?"

Zhang Yuqi listened very seriously at first, but when she heard Xu Zheng talking about her husband, she felt angry, "Damn it, I don't even have a boyfriend yet."

She resisted listening to what he said and was about to get angry. Suddenly, another policewoman in the meeting, Ji Meiyue, stood up and said, "I know, I know, my best friend, my best friend knows me from head to toe.

, knows it better than my boyfriend."

Zhang Yuqi's mind, which was dizzy with anger at this time, suddenly cleared up. She was moved in her heart. Before she could speak, Zhuang Qiang, who was not far away from her, slammed the table. The long hair on her head finally drooped down. He didn't care, "

No, there is someone who knows you better, and that is your best friend’s boyfriend, the best friend’s boyfriend who has thoughts about you!”

Xu Zheng was stunned, and everyone present was stunned. Zhang Yuqi obviously knew about Zhuang Qiang's past and looked at him with sympathy. But at this time, everyone was stunned. Apparently no one would ask why Zhuang Qiang knew so well.

Ji Meiyue and Zhuang Qiang were right. Maybe the murderer didn't find out because he was too detailed in his work, and he was too professional in grasping people's hearts and the development of things. This is enough to show that the murderer is very familiar with the victim, and can

The victim was so familiar that apart from his parents, siblings, and his best friends from school, he was only his best friend.

Of course, there are also boyfriends or husbands of best friends who have other ideas.

Po Yu finally had a direction, and Qu Hou was also happy. It was too fast. He had some clues in two or three days. He thought it would take three months to get a clue. It seemed that finding the direction was really important for Po Yu.

It's a breeze to insert butter with a hot knife.

Xu Zheng was of course very happy, because after completing this series of tricks, the system would randomly reward him with the next member of the hidden kill list. He prayed in his heart that it would be best to be number one to see how much sin he had.
