Chapter 581 I Think of a Place

Facing it was a wall of cork boards, all pinned with photographs.

Li Li, Liu Meiling, Zhang Fangfang, Xu Qingquan, Xu Qingshu, Kong Wanshan, Li Li's nanny Liu Zhen, Xu Qingshu's two children, and even their vehicles, houses, companies, training courses, parents, colleagues, etc.

It can be said that these hundreds of photos contain all the information of these nine people, and there are even some printed notes next to these photos, on which some information is noted in detail, such as hobbies and allergies, who The relationship with whom is still wired, and the details are unimaginable.

Just looking closely, you can see that there are many holes in it, and there is also a box of used pins lying on the ground.

Xu Dayuan stared at the cork wall and looked it over carefully.

"Have you noticed that there is something missing here?"

"Plans, plans at various points in time, and baking pictures, although they are on Li Li's head, there are no details. They have been carefully cleaned up here, and the traces should have been cleaned up not long ago. One step was wrong and one step was wrong. It should have been collected earlier. Take her blood sample for comparison."

Liu Yongxin rubbed his chin and said beside him.

Zhou Ning stared at the cork board, and waved to Da Zhao beside him.

"Go and check inside. If my guess is right, this is her base. Monitoring, analysis, planning, everything is done here. From her point of view, it may be the completion of the plan."

Having said that, Zhou Ning paused, why did he use the words "complete the plan"?
Zhang Fangfang was still there and was protected by the police. Xu Qingshu's two children were also within the sight of the police at this time, and they had been reported earlier if they were in danger. Kong Wanshan was outside. As for Xu Qingshu, she really didn't know her situation.

So Shi Yun, no, now she is called Zhong Xiaoyan, how did she know the progress of the police?
Before Zhou Ning could speak, Xu Dayuan had already dialed the phone.

"Have you received two children?"

"I received it. They were all in the police car. I also asked the school teacher if anyone approached the two children. I also showed the teacher Zhong Xiaoyan's photo. They said that they looked familiar, and they should have picked up the child."

Xu Dayuan breathed a sigh of relief.

"Okay, hurry up and bring the two children back, by the way, where is Xu Qingshu?"

Xiaobai was taken aback for a moment, followed by a pause in his voice.

"When I went to Xu Qingshu's house, the nanny was at home. I thought you sent someone to look for her, so I didn't ask much. Does the leader need me to find this person?"

"No, take the children and go straight back to the City Bureau. Your task is to protect the two little ones."

After hanging up the phone, Xu Dayuan quickly walked towards the first floor. When he saw Fang Mu and Liu Yufei, he quickly called them over. The phone in his hand kept calling Xu Qingshu's number, but the female voice inside reminded you that the number you dialed was turned off or not in the service area.

Hearing the sound of the mobile phone in Xu Dayuan's hand, both of them looked serious.

"What's the matter?"

"Xu Qingshu is missing, she's not at home, and she didn't go to pick up the two children. I'll ask Xiaoqu to check the monitoring immediately. The two of you will search separately, and first check any places she may go. The phone remains open."

Fang Mu's expression collapsed, like a headless chicken.

"Leader, this Xu Qingshu is a housewife who picks up her children every day, buys vegetables or cooks, and can take care of Xu Qingquan. Now the two children are not with her, and she is not at home. You are the first stop to go to the hospital." Yes, I see that Xu Qingshu is more or less fortunate, and I still want to focus on catching Zhong Xiaoyan."

Liu Yufei nodded.

"Fang Mu is right. In this way, I will have someone take Kong Wanshan to visit the homes of relatives and friends that Xu Qingshu knows. Is there no news about Peng Da's surveillance?"

Xu Dayuan shook his head.

At this time, Da Zhao ran up to the first floor, panting and waved towards Xu Dayuan.

"Leader, come down and take a look. We found a lot of monitors and computers. Xiao Qu said that these things are quite advanced, and the equipment is of a higher grade than his own. It can be regarded as a one-stop with monitoring and monitoring.

Xiao Qu restored the system and found some residual traces. According to the above notes, several mobile phones and landline phones were monitored here. Of course, there are several monitoring devices. No users are marked, so it is impossible to guess. Now all the information is being sorted out. "

Upon hearing this, several people rushed down quickly.

Seeing the cork wall, Liu Yufei and Fang Mu's eyes widened. After all, this thing is more complete than the information on the whiteboard during the project meeting of their unit. Those who have done it know how difficult it is.

Going around the cork wall, the scene behind is even more shocking. There are seven or eight computers below the monitor on one wall, and a lot of metal boxes are placed on the table. Xu Dayuan doesn't know what it is, but These devices look much more professional than Xiaoqu.

"Is there anything special in the recovered files?"

Xiaoqu nodded.

"Bureau Xu, I found out that Zhang Ping was among the people she monitored. As for the large amount of files deleted, when the suspect left the room, he formatted all the computers. I'm gradually recovering them now. Hurry up." 80% completed, and 41% completed slowly, I took a look at the content.

Among these audio materials, according to the classification in the folder, the mobile phones of several people are all equipped with monitoring devices. This is many times more advanced than the monitoring device installed by Yu Xiaoou in the previous 6.29 arson case in Jingkou District. This can be said to be Entry-level spy equipment.

How can I say that you can understand, I can do a part of the restoration, but in the use of these equipment, as well as the professional aspects of monitoring and tracking, she is much better than me, what I can see depends entirely on what she wants to keep. What, can you understand what I mean? "

Xu Dayuan narrowed his eyes, Zhou Ning spoke first:

"You mean, Zhong Xiaoyan is a master. She deliberately left some time-consuming and labor-intensive content that requires you to recover. This is a deliberate act. It should be to intercept our investigation speed and buy her time to escape?"

Xiao Qu nodded, but Zhou Ning shook his head and said:
"You think too much, Zhong Xiaoyan is a person who never wants to escape, leaving a tail here just shows her personal ability, which means that I want to wipe off all traces, so that none of you can catch me. "

Xiao Qu looked puzzled.

"A person who never wanted to escape, boss, what does this mean, Zhong Xiaoyan is not a suspect now?"

Zhou Ning nodded vigorously.

"You are right. Zhong Xiaoyan is only a criminal suspect now, but our relevant evidence is incomplete. We can only use Xu Qingquan's testimony to prove that Zhong Xiaoyan may have appeared at the scene of the traffic accident and checked whether the people on board were dead.

As for other things, Lao Yang is collecting DNA, and it will take five or six hours for the results to come out. As for the traffic accident, she overtook illegally. At the scene of the accident, there were no traces of her brakes left, let alone collided with two cars. Monitoring the driving recorder, Nothing is saved, how do you prove that Zhong Xiaoyan is the murderer? "

Xiao Qu froze, thought for a while and shook her head slightly.

"On the way here, Da Zhao said that the vehicles that fled in the accident may have left westward towards the small road that was not monitored. As for where they merged into the normal road, this cannot be detected. After all, there are bridges built around and dug everywhere. judge.

In addition, I searched for Zhong Xiaoyan's car number, but there was no one around, but there was one person's car, which appeared on the section of the Huanwan Expressway in the early morning of September 9. I intercepted the surveillance screen, although I couldn't see the whole picture , but it can be seen that the driver is a woman. "

Zhou Ning and Liu Yongxin looked at each other, and they exclaimed together:

"Could it be Zhang Fangfang's car number?"

Xiaoqu nodded and quickly found the screenshot.

"This is the screen I intercepted. It can be seen that the driver of the vehicle is a female, very thin, not very tall, wearing a white short-sleeved T-shirt with dark pants or skirt underneath, but the face cannot be seen clearly. "

"Use the face recognition system and try to analyze who is closer to Zhong Xiaoyan or Zhang Fangfang."

"Compared, because only the lower jaw is exposed, the mouth is not open, and the hair is loose. The similarity between the two is 49% and the other is 50%. After all, what is exposed is the least distinctive part."

This stumped Zhou Ning, Xu Dayuan took out a cigarette, thought about not lighting it, and said with a frown.

"I have a feeling that this revenge is not over. After all, there are still two people who caused the accident that year have not been sanctioned, and she really did a perfect crime. If Xu Qingshu was kidnapped, then Zhang Fangfang would not care about her? This is not like her behavior .”

Zhou Ning shook his head, pointed to the photo in front of Xiao Qu and said:
"It's not that I don't care about it. First, Xu Qingquan said that there are two people who use this niche brand of perfume. One is Zhong Xiaoyan, and the other bought Zhang Fangfang of the same style because he smelled it on Xu Qingquan. It is suspected that Zhong Xiaoyan saw the scars on her fingers at the scene of the car accident;
Second, after Xu Qingquan’s DNA test, on the way back to Qindao, he chose an unmonitored location, took advantage of the time difference, and passed through the car interchange, which caused the car accident. The testimony of Xu Qingquan.

Moreover, the nature of this car accident needs further investigation. After all, both the large truck and the police car are suspected of speeding. As for the car that passed the police car in the same direction, it was even more speeding, but she did not have an accident with the other two cars. Collision, there is no trace left at the scene, so it cannot be proved;

On the morning of September 9, Zhang Fangfang's car appeared at the scene of the crime, still on the Haiwan Expressway, with the same perfume. I don't know if Zhang Fangfang had injuries on her hands. If so, wouldn't all the suspicions fall on Zhang Fangfang?Is this a form of revenge?
What's more, the DNA found in Liu Meiling's autopsy was compared with the DNA of all the women involved in the case, and all women's little fingers were checked for cuts. As for Xu Qingshu, if she was taken away by Zhong Xiaoyan, I would think a place. "

Both Liu Yongxin and Xu Dayuan looked at Zhou Ning, and asked hopefully:

"Where?"
