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 the 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 are probably in Ichibashi District and Xuangui District. There is also the accidental tragic death of the deliveryman. It happened when he was delivering express delivery." On the way, 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 deliveryman. It's just that I checked the customers who complained about this deliveryman 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 case was defined as an accident.
At this time, there were two colleagues from the criminal police detachment who were responsible for a case six years ago. They said: "The murderer in the case we are responsible for committed the crime so seamlessly. If it weren't for coincidence, I guess it's not the same. At present, We still don’t have any clues.”
Xu Zheng turned on the computer and turned to the case he was talking about. Six years ago, in the summer, when a community in Changming City opened for business, an aunt who was working as a caretaker screamed hoarsely for a long time because she was too involved in her job. As a result, she suffered a heart attack. Then he died. The investigators combined the case this time. First, the aunt was 54 years old. She just had a physical examination and all physical indicators were normal. Second, it happened to be her birthday. Third, the aunt was never found with her at the scene of the crime. Fourth, the medical examiner concluded that the cause of death was myocardial infarction, the rescue was not timely, and no drug was found to be a factor in the condition at the time.
At this time, the beautiful policewoman put forward another concept, "Do you think, besides coincidence, do these cases 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 neatly, "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 accidental killing 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. His inner side is narrow-minded and extremely vindictive. In reality, he should be a gentle and generous person. "
Xu Zheng was speechless. This was psychological profiling. As expected, there was always something out there, 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 play accidental murders so smoothly, and he has no confidence in the police's handling of the case." The method is very familiar, but the age cannot be too young.
Huo Weian and Ji Meiyue, do you have any clues about the key suspects in the Hitotsubashi and Black Turtle districts? "
The key suspects Qu Hou mentioned were lawyers, judges and other successful people in society who had some connection with criminal investigation. But these two people stood up, lowered their heads, as if they 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 are a primary school student answering questions! If you have something to say, just say it, and if you have something to say, let it go. Let's discuss it. Who doesn't say what 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 case and the young woman jumping off building case. I think this way, the murderer must be very aware of the living habits of these two female victims, and even has no idea about jumping off building." Su Nanying also knows a little about her husband’s work and habits.
Captain Zhang, you are a woman. Think about it, besides your husband, who else knows everything about you? "
Zhang Yuqi listened very seriously at first, but when she heard Xu Zheng talking about her husband, she felt angrily, "Fuck, 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."
At this time, Zhang Yuqi's mind, which was dizzy with anger, suddenly became clear. She was moved in her heart. Before she could speak, Zhuang Qiang, who was not far away, slammed the table. The long hair on the top of 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, your 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. Obviously no one would ask why Zhuang Qiang knew so well.
Ji Meiyue and Zhuang Qiang were right. Maybe the murderer was not discovered because the case he did was too detailed, his grasp of people's hearts and the development of the matter were too professional. This is enough to show that the murderer is very familiar with the victim, and he can do this The victim was familiar with, apart from his parents, brothers and sisters, and his best friend from school, he was only his best friend.
Of course, there are also boyfriends or husbands of best friends who have other ideas.
The case finally had a direction, and Qu Hou was also happy. It was so fast, and 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 a piece of cake for solving the case.
Of course Xu Zheng was also very happy, because after completing this series of cases, 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 guilt he had.
But what Xu Zheng didn't know was that he had been deeply remembered by Zhang Yuqi and dared to molest her in public. She would definitely have to deal with Xu Zheng if she had the chance.
