Xu Dayuan waved his hand.

"What else do you sell with me, if you have any ideas, you can just say it, I'm here now, I also want to hear your opinion with Lao Liu, I'm always panicked, I can't say what it feels like, it seems that the murderer is staring at our actions."

Seeing that several people were looking at him, Zhou Ning did not pause, and from behind Da Zhao, he took out a blank piece of paper with three names written on it.

"We know too little information now, but we know that the three women who had an affair with Xu Qingquan, Li Li, Liu Meiling, and Zhang Fangfang are classmates, and some people say that they are friends and best friends for many years, but Zhang Fangfang denies this relationship.

So I said, you need us to send someone to Henan Province to understand, go to the hotel to analyze from the perspective of traces, and help find all the information about Liu Meiling, after all, it has been more than ten days since the 20th, and the possibility of being killed has increased.

However, I think the most important thing now is to understand all the information about these three people, from childhood to adulthood, what conflicts or grudges there are between the school and their classmates in elementary and junior high school, or what big things happened when they were in school, I believe that there is no hatred for no reason.

There must be a relationship between the murderer and the three of them, and the three of them were at the same time, and something happened at the same time, just like the cause of the serial murder case in Hai'an City, which was the bullying in childhood.

Do you remember the copper hammer grass that Peng Shinian found? He said that that thing is in the Qindao area, the area that can be distributed is limited, and it is most likely to appear in the kind of sunny cemetery, not the current cemetery, and the murderer chose to go to the cemetery to pay tribute before he started, I think it is a mourning for the deceased, but also a consolation to them. ”

Xu Dayuan paused and nodded slightly.

"I also remember why I feel familiar with what you said, just like the case of Hai'an, all the heads were sent to Cui Shangyu's grave to pay respects, this is to comfort the souls of the dead, not to mention that such an analysis can be connected, but the dose of vitamin A poisoning, most people don't know much, will it be a medical student?"

Zhou Ning pondered for a moment, then shook his head.

"It's not necessarily a medical study, this is not an obscure medical knowledge, it's just that many people don't know how big this poisoning dose is, and how to add it, to mask the taste, and even how much dose can work.

I think that the murderer must have done a special test, slow poisoning many times, easy to be discovered, a single dose is too large, will cause a short period of rapid poisoning, the murderer needs to find a person can be poisoned enough, to achieve a certain effect, and will not attack in a short time. ”

Xu Dayuan had already stood up, and on the piece of paper written by Zhou Ning, he recorded all the questions that Zhou Ning had just said, and then he took a long breath.

"This analysis is very reliable, I know that you must have a direction, especially in the period when the investigation is in a bottleneck, it is too critical for us to find a breakthrough point."

Liu Yongxin glanced at it.

"Xiaoqu doesn't have Li Li's WeChat, since the end of last year, WeChat has been registered, and many students who have not been in touch for many years have engaged in various groups, let him see if there is any information there?

As for this Xu Qingquan, although he is a year older than the three of them, he can also check it, and he will not be picked up for no reason, just because he is a sea king, he will not be wiped out, check their original household registration, and Da Zhao will call someone. ”

Xu Dayuan nodded, leisurely opened a bottle of mineral water, completely lost the previous panic, Zhou Ning glanced at him.

For some reason, he always felt that Xu Dayuan's previous nervousness and worry had an element of acting, and he really felt relaxed at this time, did he want to call their master and apprentice, and then conduct Xiaoqu to help with the inquiry?

If you have an idea, just say it, isn't this a bit big in the circle?

Just thinking about it, Xiaoqu was dragged in by Da Zhao, Da Zhao carried the notebook in one hand, and quickly stuffed it into Xiaoqu's arms, and then raised his chin towards Xu Dayuan.

"The leader wants to ask you for help, he is embarrassed to speak in person, he just talked to Zhou Xiaozhou, and asked if you can log in to Li Li's WeChat and look it up, her various groups, preferably classmates, the kind of elementary and junior high school classmates, if there is news of classmates in the dance school group, you can also search for it."

Xiaoqu didn't ask any nonsense, quickly took the notebook in Da Zhao's hand, opened the operation, and logged in to Li Li's WeChat, and then selected all the groups.

There are eight groups in the dance school, one group of teachers, and seven groups for the examination, and Da Zhao's face is full of surprise.

"Now that I'm learning a dance and taking a grade, what's the point of this thing?"

Xiaoqu explains:

"I took a look at it before, and it seems that if you want to take the college entrance examination for art students in the future, having this registration certificate is a plus, and when you take the major, I'm afraid these trainings are specially designed for exam practice."

Da Zhao realized, he really didn't know this, and Xu Dayuan didn't dare to talk nonsense in Da Zhao.

After a while, Xiaoqu found three groups of classmates, one marked the fifth class of Gulou District Experimental Primary School, there were 44 people in it, one marked the 97th grade department of Gulou District Experimental Middle School, there were 312 people, and the last one was simpler, the second and second class classmates association, there were only 12 people here.

"The experimental primary school in Gulou District, in the late 90s, did implement a few years of five-year primary education, and it seems that this class is like this."

No one answered, Xiaoqu clicked on the chat box in the group, in the group with the most people, Li Li spared no effort to advertise, in the primary school group, Li Li almost never spoke, it is estimated that there are few people who dislike it.

As for the second and second class reunions, Li Li is very reserved, she didn't mention the dance school, but mostly talked about the classmates in which class and which grade, how they are now, and she can feel that the relationship between the 12 people here is very close.

However, a class, especially in the junior high school in Qindao, I am afraid that there were sixty or seventy people in that era, and it seems that it is really a small circle with good relations, Xu Dayuan poked Xiaoqu.

"Xiaoqu, let's see if there are Liu Meiling and Zhang Fangfang among the 12 people here, the mobile phone numbers of the two of them are here, although the names are messy, the mobile phone numbers can still match."

Xiaoqu tried it, and found two WeChat accounts in a moment, one is called Linglong Heart in Linglong Chess, which is marked as Liu Meiling by Xiaoqu, and Zhang Fangfang is marked below by Xiangke.

With the operation, Xiaoqu no longer had to be instructed, and directly logged in to Liu Meiling and Zhang Fangfang's WeChat, and even the password was not cracked, and the software was still running next to it, constantly popping up some mobile phone numbers and identity information, Xu Dayuan rubbed his nose.

"Fang Mu, are they looking for you?"

Xiaoqu grinned.

"Well, don't worry, the simulator I use, there will be no computer login prompt on the phone after this login, that is, you can see the actual situation in her WeChat, and even the deleted content can be seen, there is nothing special in the WeChat of the two of them, and there is very little ambiguity between Xu Qingquan.

In this group, in addition to Li Li, Liu Meiling and Zhang Fangfang, the remaining nine people I personally feel are all men, their registered mobile phone numbers, I inquired, one of the eight is non-real-name, but the mobile phone number is the old number, you can call one of the eight to ask. ”

Da Zhao shook his mobile phone towards Xu Dayuan, Xu Dayuan nodded slightly, Da Zhao dialed the number of one of the people, and directly called the person's name after dialing, a Qindao accent, and gave the other party a lecture.

Of course, in the end, I asked who the mobile phone number was, after all, the call was not saved in time, and after a long time, I forgot to mark it, and the last goodbye was to have a drink together next time.

Liu Yongxin couldn't help laughing on the side, hung up the phone, Xiaoqu's search had ended, and said with a long breath:

"This person is also 28 years old, and it is true that the previous household registration was near the Gulou District Experimental Middle School, and they chatted a lot, but I searched for it, and there were no sensitive words, just some memories."

Xu Dayuan didn't speak, Liu Yongxin took the first step and said:

"According to the information provided by the teachers in the dance school, I think it is still more accurate, and it is relatively close to Li Li, as for Liu Meiling and Zhang Fangfang, as for Zhang Fangfang's disdain for Li Li, I think it is still related to Xu Qingquan, and the leaders of these people will come over and ask."

Xu Dayuan kept nodding and motioned for Xiaoqu to send him all the personnel lists and numbers.

"I don't have many people available at hand now, just don't be so troublesome, let's get it together, talk about one by one, I think this is our home field, and I will say anything as soon as I say something, but over there in southern Henan, hurry up and send someone to set off, I still insist on sending someone over, and we will not delay."

Zhou Ning thought about it, Da Zhao had already raised his hand, but Zhou Ning shook his head.

"It's not to investigate the scene over there, what is needed now is to search, find traces, analyze the area where Liu Meiling may leave, and of course it may also be the way for the deceased to transfer the body, let Zhu Xingxing lead the team, Lao Yang, Sun Gaotie, Wang Jianjian, Zou Jialong, Pang Tianhang follow."

Xu Dayuan naturally had no opinion, signaling that this arrangement was okay, Da Zhao sighed, quickly took out his mobile phone, dialed Zhu Xingxing's phone, and made arrangements.

At this time, the work of contacting the male classmates in the second and second groups had already been ordered, Xu Dayuan sent a location to Xiaoqu, signaled him to open the map, waved his hand at Liu Yongxin and Zhou Ning, and said:

"Anyway, it will take some time for people to come over, don't be idle, hurry up and help me see, this location, is there that kind of satellite map, that is, it looks like a map taken from a high altitude, Fang Mu called me and told me a lot of surrounding conditions, I have no concept at all."

Zhou Ning was also interested in this sentence, patted the little song, and raised his chin towards the big screen.

"Xiaoqu, projected on the big screen, I also want to know, the situation around this hotel, can it be determined that Liu Meiling went to Henan Province on the 18th, where did she stay? Drive straight over, so is the vehicle found? If the car hadn't driven away, wouldn't the surveillance of her leave the hotel with nothing to discover? ”
