Chapter 562 The Secret We Don't Know
Xu Dayuan waved his hand.

"What's wrong with me? Just tell me what you think. I'm here now to hear your opinion and Lao Liu's opinion. I'm always flustered. I can't tell what it feels like. It seems that the murderer is staring at us. act the same.”

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

"We now know too little information. We only know that the three women who had an affair with Xu Qingquan, Li Li, Liu Meiling, and Zhang Fangfang, are classmates. Some people say that they are good friends and girlfriends for many years, but Zhang Fangfang deny the relationship.

So I said, you need us to send people to Henan Province, I understand, go to the hotel to analyze from the perspective of traces, and help find all information about Liu Meiling. After all, NO.20 has been more than ten days today, and the possibility of being killed increase.

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 enmity they have with their classmates in elementary school, junior high school, or what major events happened when they were in school. Believe that there is no gratuitous hate.

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

Do you remember the copper hammer grass that Peng Shinian discovered?He said that the thing is in the Qindao area, and its distribution is limited. It is most likely to appear in the sunny cemetery, not the current cemetery. Grief is also a consolation to them. "

Xu Dayuan paused and nodded slightly.

"You said this, and I also remembered why I felt familiar. Just like the Hai'an case, all the heads were sent to Cui Shangyu's grave to pay homage. The dose of vitamin A poisoning is not well understood by ordinary people, could it be someone who studied medicine?"

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

"Not necessarily a medical student. This is not some obscure medical knowledge. It's just that many people don't know how big the poisoning amount is, and how to add it to cover up the smell. It's even said, how much dose can be effective. .

I think, the murderer must have done a special experiment, slow poisoning and many times, it is easy to be discovered, a single dose is too large, it will cause rapid poisoning in a short time, the murderer needs to find someone who can poison people enough to achieve a certain effect, not yet Amount that occurs for a short period of time. "

Xu Dayuan had already stood up, recorded all the questions that Zhou Ning said just now on the piece of paper that Zhou Ning wrote, and then he let out a long breath.

"This analysis is very reliable. I knew you must have a direction. Especially when the investigation is stuck in a bottleneck period, it is very important for us to find a breakthrough point."

Liu Yongxin glanced at it.

"Didn't Xiaoqu have Li Li's WeChat account? Since the end of last year, he started registering on WeChat account. Many students who haven't contacted him for many years have set up various groups. Let him see if there is any information in it?
As for this Xu Qingquan, even though he is one year older than the three of them, he can be checked. He will not be brought along for no reason. call someone. "

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

For some reason, he always felt that Xu Dayuan's previous nervousness and worry had something to do with acting, but now he really felt relaxed. Could it be that he wanted to order their master and apprentice, and then direct Xiaoqu to help with the investigation?

If you have an idea, just say it. Isn't this a bit of a circle?
Just as he was thinking, Xiao Qu was dragged in by Da Zhao. Da Zhao held the notebook in one hand and quickly stuffed it into Xiao Qu's arms, then raised his chin towards Xu Dayuan.

"The leader wants to ask you for help, but he is too embarrassed to speak up 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 the classmate group, the kind of primary school Classmates in junior high school, if there is news about classmates in the dance school group, you can also search for it."

Xiao Qu didn't ask any nonsense, quickly took the notebook in Da Zhao's hand, opened it for a while, 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 of applicants for grade examinations. Da Zhao's face is full of surprise.

"Now I'm learning a dance, and I have to take a grade test. What's the point of this thing?"

Xiaoqu explained:
"I looked at it before. It seems that if the college entrance examination is to be an art student in the future, having this registration certificate is a plus. When you take a major, these trainings are probably designed for the exam."

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

Not long after, Xiaoqu found three groups of classmates, one was marked with the Gulou District Experimental Primary School Class 44 every five years, and there were 312 people in it, the other was marked with the Gulou District Experimental Middle School Class Nine and Seven, with 12 people, the last one was simpler, and the second There are only [-] people in the class two reunion.

"The Experimental Primary School in Gulou District, in the late 90s, did implement five-year primary school education for several years. It seems that this class is like this."

No one answered, Xiao Qu 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 hardly spoke, probably because she disliked the lack of people.

As for the reunion of the second and second class, Li Li was very reserved. She didn't mention anything about the dance school. She mostly talked about the students in which class and grade, and how they are doing now. I can feel that there are 12 people here. very close.

But one class, especially the junior high school in Qindao, probably had 70 to [-] students at that time, it seemed that it was really a small circle with good relations, Xu Dayuan poked a little song.

"Xiao Qu, let's see if there are Liu Meiling and Zhang Fangfang among the 12 people here. Their mobile phone numbers are here. Although the names are messed up, the mobile phone numbers can still be matched."

Xiao Qu tried it out, and found two WeChat IDs in a short while, one was called Linglong Chess Zhong Linglongxin, which was marked as Liu Meiling by Xiao Qu, and the other was called Xiangshou, which was marked with Zhang Fangfang.

Following the operation, Xiao Qu directly logged into Liu Meiling's and Zhang Fangfang's WeChat without any instructions, and didn't even crack the password, and the software was still running beside it, and some mobile phone numbers and identity information kept popping up, Xu Dayuan rubbed his nose.

"Fang Mu and the others are looking for you?"

Xiao Qu bared his teeth and smiled.

"Well, don't worry, I use an emulator. After logging in, there will be no computer login prompt on the phone. I can see the actual situation in her WeChat, and even the deleted content. There is nothing in the WeChat of the two of them. In particular, there is very little ambiguity with Xu Qingquan.

In this group, apart from Li Li, Liu Meiling and Zhang Fangfang, I personally feel that the remaining nine people are all men. I found their registered mobile phone numbers. One of the eight is not their real name, but the mobile phone number is an old one. , You can call one of these eight and ask. "

Da Zhao shook the phone towards Xu Dayuan, Xu Dayuan nodded slightly, Da Zhao dialed one of the people's number, and called the person's name directly after dialing, with a Qindao accent, and gave him a scolding.

Of course, at the end, I also asked whose mobile phone number it was. After all, I didn’t save it in time for the call before. After a long time, I forgot to mark it. The last farewell message was to have a drink together next time.

Liu Yongxin couldn't help laughing, hung up the phone, Xiaoqu had finished searching, and said with a long breath:

"This person is also 28 years old. It is true that his registered permanent residence was near Gulou District Experimental Middle School. They chatted a lot, but I searched it. There are no sensitive words, just some memories."

Xu Dayuan didn't speak, Liu Yongxin spoke first:
"According to the information provided by the teachers in the dance school, I think it is quite accurate. The only ones who are close to Li Li are Liu Meiling and Zhang Fangfang. As for Zhang Fangfang's disdain for Li Li, I think it has something to do with Xu Qingquan. Get a few people over and ask."

Xu Dayuan kept nodding, indicating to Xiaoqu to send him all the personnel lists and numbers.

"I don't have many people available right now, so don't be so troublesome, get them here together, and talk to each other. I think this is our home field, and we can talk about everything as soon as we make a fuss. But on the south side of Henan, hurry up and send someone Let's go, I still insist on sending someone there, we will not delay."

Zhou Ning thought for a while, 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, and analyze the area where Liu Meiling may have left. 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, and Wang Hen inspect the area." , Zou Jialong, and Pang Tianhang follow."

Naturally, Xu Dayuan had no objection, and indicated that the arrangement was fine. Da Zhao sighed, quickly took out his mobile phone, dialed Zhu Xingxing's number, and made arrangements.

At this time, the job of contacting the male students in the [-]nd group had already been ordered. Xu Dayuan sent a location to Xiaoqu, motioned him to open the map, waved towards Liu Yongxin and Zhou Ning and said:
"Anyway, it will take some time for someone to come over. Don't be idle. Help me to see if there is a satellite image of this location, which looks like a map taken from high altitude. Fang Mu called me and said I have no idea about many surrounding situations.”

Zhou Ning also became interested in these words, patted Xiaoqu, and raised his chin towards the big screen.

"Xiao Qu, cast the screen on the big screen. I also want to know the surroundings of this hotel. Can you confirm that Liu Meiling went to Henan Province on the 18th? Where is she staying? If you drive directly there, is the vehicle found? If the car is not open Let's go, she left the hotel's surveillance and didn't find anything?"
