The two returned to the research and judgment room, and without waiting for instructions, Xu Zheng sent the record of the inquiry just now to the notebook in front of everyone, and at the same time briefly said his judgment.

Qu Hou nodded, "I agree with Xu Zheng's idea, although the 19 dating site has been closed, but you can still find a screenshot of the chat on the website at that time, which shows that the chat dialog box only has an avatar, if one person registers two accounts, the avatar and information are the same as Cai Xiaokun and Su Nanying, and they know their mobile phone numbers at the same time, so they can be completely transferred." ”

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

At this time, a beautiful policewoman said: "Team Leader Qu, colleagues, I found that these five cases are probably in Yiqiao District and Xuangui District, and the accidental tragic death of the delivery man was on his way to deliver the courier, indicating that the murderer can often observe him, does that mean that the murderer lives or works, probably the area is the area that the delivery man is responsible for." ”

The bald man who was transferred from the Criminal Police Brigade of the Ichibashi Branch slapped the table, "I also judged so, and this person must have had a conflict with the delivery man, but I checked the complaint against the delivery man before the accident, and I didn't find any suspicions." ”

Qu Hou groped his beard, "Zhuang Qiang, you will check on those people back then, don't make too much noise, it's only been three years, and those people will probably not move or leave this city, if there is, focus on strict investigation." ”

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

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

At this time, there were two colleagues in the criminal police detachment, who were in charge of a case 6 years ago, and they said: "The case we are responsible for, the murderer is too seamless, if it is not a coincidence, I guess it is not together, at present, we still have no clues." ”

Xu Zheng turned on the computer and turned to the case he said, six years ago, in the summer, a community in Changming City opened, and an aunt who was a nurse was too involved in it, and shouted hoarsely for a long time, which caused a heart attack and died on the spot. The case-handling staff combined the case this time, first, this aunt is 54 years old, she has just had a physical examination, and her physical indicators are very normal; The second coincidence is that it was her birthday; the third is that the water cup that the aunt carried with her has not been found at the scene of the crime; Fourth, the forensic doctor concluded that the cause of the aunt's death was a heart attack, and the rescue was not timely, and no drug inducement was found under the conditions at that time.

At this time, the beautiful policewoman put forward another concept, "Do you think that in addition to the coincidence of the crime, do these cases have some things in common?" ”

Xu Zheng was a little curious about this 30-year-old beautiful policewoman, and there was no doubt about his 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 sub-bureau, Zhang Yuqi, the woman does not let her shave her eyebrows, and there is news that she may be able to be transferred to the detachment this year."

Of course, the questions of colleagues about the beauty are very positive, and they have to say a few words casually if they don't find it, no, some people saw that the colleagues in front of them had finished saying everything they could say, so they made it up: "The common ground, I think there is one thing that cannot be avoided, that is, the victim and the murderer have a grudge, and the hatred is as deep as the sea!" ”

Xu Zheng and the others couldn't hold back, and almost laughed, isn't this obvious, why did they spend so much effort to design an accidental killing?

However, Zhang Yuqi slapped the table vigorously and spoke sharply, "I think everyone has fallen into a misunderstanding, there is a contradiction is a possibility, so why can't there be no contradiction?" Maybe the murderer was itching in his heart, and he felt that this kind of accidental murder could bring him infinite refreshment?

Maybe there is only a little contradiction between them, but if the murderer is extremely narrow-minded, then why can't he take revenge because of a quarrel?

In my opinion, the murderer should be around 40 years old, male, and should have a successful career. Narrow-minded and vindictive, it is his heart, and in reality he should be a gentle and generous person. ”

Xu Zheng was speechless, this is a psychological profile, sure enough, there is a sky outside the sky, there are people outside the world, he has not learned it yet, and he does not dare to do psychological profile, otherwise it is extremely easy to mislead himself.

Qu Hou looked at Zhang Yuqi at this time and smiled with satisfaction, and even took the lead in applauding, "I think it is feasible for Captain Yuqi's psychological profile, this person can play accidental murder so slippery, and he is very familiar with the police's methods of handling cases, but his age cannot be too young."

Huo Wei'an, Ji Meiyue, do you have any clues about the key suspects in charge of the Yiqiao District and the Xuangui District? ”

The key suspects Qu Hou said were lawyers, judges, and other successful people in society who had something to do with criminal investigation, but these two people stood up, lowered their heads, and looked like they had admitted their mistakes.

Qu Hou waved his hand, this day has to screen hundreds of people, besides, the effect of ordinary touch row is definitely not big.

Xu Zheng also had an idea at this time, so he raised his hand, and when Qu Hou saw it, he scolded with a smile: "You elementary school students answer questions!" If you have something to say, if you have a fart, let's discuss, who doesn't have something to say, and if you say something wrong, you're afraid of being laughed at? ”

Everyone laughed again, Xu Zheng saw it, Zhuang Qiang laughed the loudest, and a few stubborn hairs around the bald head couldn't cover the bare top by his laughter.

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 the building, I think so, the murderer must be very aware of the living habits of these two female victims, and even have a little understanding of the work and habits of Su Nanying's husband in the jumping case."

Captain Zhang, you are a woman, do you 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 was indignant,, my mother didn't even have a boyfriend.

Forced to listen to him, she was about to get angry, suddenly, another policewoman in the meeting, Ji Miyue, stood up, "I know, I know, my best friend, my best friend can say that she knows me from head to toe, better than my boyfriend." ”

Zhang Yuqi's mind that was dazzled by anger at this time also sobered up instantly, her heart moved, and before she could speak, Zhuang Qiang, who was not far away, slapped the table violently, and the few long hairs on the top of her head finally drooped down, and he didn't care, "No, there is someone who knows you better, that is your best friend's boyfriend, your best friend's boyfriend who has thoughts about you!" ”

Xu Zheng was stunned, everyone present was stunned, Zhang Yuqi obviously knew Zhuang Qiang's past, and looked at him sympathetically, but at this time, everyone was stunned for a moment, obviously no one would ask Zhuang Qiang why he was so clear.

Ji Meiyue and Zhuang Qiang are right, maybe the murderer didn't find out, because the case he did was too detailed, and he was too professional in grasping people's hearts and developing things, which is enough to show that the murderer is very familiar with the victim, and can be so familiar with the victim, in addition to his parents, brothers and sisters, plus a friend who learns to die, there are only girlfriends.

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

The case finally has a direction, and Qu Hou is also happy, this is too fast, and there will be some clues in two or three days. He thought it would take three months to see his eyebrows, and it seemed that finding the direction was really a hot knife into butter for solving the case, and it was a breeze.

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 killing list, and he prayed in his heart that it was best to be the first to see how much sin he had.

But what Xu Zheng didn't know was that he had been deeply remembered by Zhang Yuqi, and he dared to tease her in public, and she would definitely have to clean up Xu Zheng if she had the chance.
