"Who?"

"Sun Manqing, Zhang Guanglei was eating with Sun Manqing, the two seemed to meet by chance, Sun Manqing sat down first, and then Zhang Guanglei came over, both of them were a little surprised, but it seemed that they chatted for a while, and after eating in a hurry, the two left one after another.

However, from another monitoring point of view, it seems that there is a man who has been following Zhang Guanglei, but the man is wearing a hat and can't see his face clearly, and the surveillance video has been sent to your email. ”

Zhou Ning heard the sound of the mobile phone, and quickly clicked on it, and the two videos he received, obviously this was already a screenshot video.

Sun Manqing and Zhang Guanglei met, but there was no tension, Sun Manqing paid the money, Zhang Guanglei was not very polite, and sure enough, when the two got up, a man in the corner quickly followed.

The monitoring time at this time is 7:30, and having breakfast at this time is the same as the analysis in Zhou Ning's autopsy, but there is no surprise.

However, Zhang Guanglei and Sun Manqing had breakfast together, no matter how you look at it, it is a little incredible, Zhou Ning's eyes were attracted by the person in the video corner.

Da Zhao hurriedly clicked on another surveillance clip, this angle can be a little stronger than that, the man in the corner followed Zhang Guanglei towards the side of the road, and when he turned his head in the direction of monitoring, he raised his hand and held his hat.

Zhou Ning raised his hand and asked Da Zhao to click the pause button, the huge thumb joint made Zhou Ning recognize who this person was at a glance, but seeing the hair in his ear, Zhou Ning frowned slightly.

"Are you wearing a wig? The characteristics of this finger are the same as those of Chen Chunxi, and it seems that when I searched his car in the morning, I still ignored some details. ”

Da Zhao glanced at him.

"What do you still want to do, really think that you are a fortune teller, and when you turn the compass, you will know who the murderer is? Don't you want to roll up here desperately, so that no one can live? But this hair, I don't look like a fake, I guess it's to change the appearance and not attract the attention of others, so I cut my hair yesterday. ”

Zhou Ning agrees with this analysis, but according to this line of thought, Chen Chunxi wants to kill Zhang Guanglei, which is a little unreasonable, especially that Wang Mengmeng, who obviously helped Chen Chunxi, and they completely pushed Sun Yannian as a scapegoat.

The conversations just now, as well as the various records related to it, are all properly calculated, and this degree of thoroughness is really not easy, and it will also turn the criminal police team around.

So, why can Chen Chunxi cooperate with Wang Mengmeng?

In order to prove that he was not at the scene, Wang Wenjing even broke himself, what is the reason for all this?

Zhou Ning was stunned, and the word Dalong popped up in his mind, and he stood up directly.

Zhang Guanglei is introverted, not good at words, even unsociable, does not like to socialize, and is too different from Yu Beauty, and then he is with Wang Wenjing.

Wang Wenjing's mother was against it, as for Wang Mengmeng's attitude, it was even more telling, but they still persisted for more than two years, and Zhang Guanglei's poisoning also lasted for more than a year, could it be that Zhang Guanglei has been pestering Wang Wenjing.

In order to get rid of him, Wang Wenjing directly poisoned him, and found that poisoning 'could not kill', which could only make his health worse, so he simply arranged such a 'car accident'.

If it is determined to be a car accident, it is better to have a lot of compensation from insurance, and if it is not recognized as a car accident, at least Sun Yannian will carry it.

However, there is a variable in this, that is, Zhou Ning followed to help.

At this moment, Zhou Ning's mobile phone rang, and he connected directly.

"I'm Zhou Ning!"

"Well, this is the laboratory, I did six extractions of the poison detection test you asked for just now, and found the ingredients of Da Long in the dead skin of Wang Wenjing's nails, which are exactly the same as the toxins and impurities extracted from the blood of the deceased.

In addition, on the fiber extracted from the claw hammer, we were lucky to find a male DNA, which was consistent with Chen Chunxi, who was previously sent for testing. ”

Zhou Ning was extremely embarrassed, although Cui Lili's attitude was still cold, but people were people who worked, and they didn't have to please anyone, so that people would work overtime, which was good enough.

"Thank you, Sister Cui, you guys should get off work quickly, I won't send it for inspection here today!"

Da Zhao gasped, excited and didn't know what to do.

"Zhou Xiaozhou, we don't have a report at hand now, shall I go and get it?"

As he was talking, Zhou Ning's mobile phone rang a few times again, and then he received the email for the test, Da Zhao ran out with a smile, this does not need to be explained by others, he knows where to print.

Zhou Ning patted his chest and pushed the call button away.

"Xu Da, please come out, there are feedback on the results of the investigation everywhere, we guessed right!"

Zhou Ning guessed correctly, which made Xu Dayuan raise his eyebrows unconsciously, stood up and handed the tissue to Chen Chunxi.

"You control your emotions first, and we'll move on later."

After saying that, Xu Dayuan walked out quickly, and the clerk also came out, and there were only two left, Chen Chunxi and Wang Mengmeng, who were left in the huge interrogation room, Wang Mengmeng still hung her head, but her hand had already reached out in front of Chen Chunxi and took out a tissue.

At the same time, there was an exchange between his eyes and Chen Chunxi, Chen Chunxi pursed his lips, his face lost the comforting look he had just now, and with a hint of warning in his eyes, Wang Mengmeng hurriedly covered his face with a tissue.

This series of actions, if you don't look carefully, you can't find it at all, but Da Zhao doesn't blink, and he takes this scene into his eyes.

Chen Chunxi was warning Wang Mengmeng, and seemed to be extremely dissatisfied with Wang Mengmeng's performance, see? See? I think they must have rehearsed it before, maybe they analyzed what might happen later, but now it's not what they expected. ”

Xu Dayuan glanced at the single-sided glass, and glanced at Da Zhao, this product is really a bit boring.

"We're not blind, we've all seen it, Zhou Xiaozhou said what you found?"

Zhou Ning hurriedly said two phone calls and test results, and Xu Dayuan heard that there was obvious surprise on his face.

"Zhang Guanglei and Sun Manqing had breakfast together, or they met by chance, this is a coincidence, but Chen Chunxi's DNA can be found on the murder weapon, this is ironclad evidence, it seems that he has been following Zhang Guanglei, but when did he catch up?"

Zhou Ning and Da Zhao both shook their heads, and then Zhou Ning looked at Chen Chunxi in the interrogation room.

"This, maybe I have to ask Chen Chunxi."

Xu Dayuan flipped through his phone, found the picture sent by Xiao Zeng before, opened it and read it.

"Yesterday, Xiao Zeng retrieved their call records, and at 7:44, Sun Manqing received a call from Yu Meimei, which is consistent with Sun Manqing's actions in the video, he walked a little later than Zhang Guanglei, I think he should have seen the person who followed Zhang Guanglei, so I want to follow and see."

Zhou Ning nodded, judging from the video, Sun Manqing glanced in his direction after seeing Zhang Guanglei leave, then answered a phone call and delayed for two minutes, and then walked towards the side of the road until he was out of the monitoring range.

"The remaining Da Long in Wang Wenjing's nails, although it can be used as evidence that she poisoned Zhang Guanglei, but I still want to check Zhang Guanglei's house, Wang Wenjing must have done a very secret job of poisoning for such a long time, if they find this, I think they have nothing to hide."

Xu Dayuan glanced at his watch, it was already 18:49 at this time, then nodded, and put his hand on Zhou Ning's shoulder.

"I won't say more polite words, I'll start the interrogation of Chen Chunxi immediately, you have news to call me."

Da Zhao also stood up and came over.

"I'll go with you, our group of trace tests is too small, it's not enough at all."

Zhou Ning shook his head, there is indeed a shortage of people, but what is lacking is the people who work, there are a lot of traces of contact with the technical department of the city bureau, the old, the middle and the young have but there are not many who really put their minds on the eucalyptus, especially the criminal eucalyptus was originally a weakness of the city bureau, which was a little difficult, so I wanted to find experts in the province.

"Here we go."

After speaking, Zhou Ning dragged Da Zhao out, Xiao Zeng ran out of nowhere, and saw the two of them hurrying over.

"Xu Da asked me to go to Zhang Guanglei's house with you, do you want to go now?"

Zhou Ning nodded, a few people didn't talk nonsense, and quickly got in the car and arrived at Zhang Guanglei's house.

There are policemen staying at the door, open the door and enter, the room is filled with a musty smell, it seems that the deceased is not a very clean person, turn on the light and look at the room, the cleanest is probably the kitchen, it can be seen that Zhang Guanglei almost does not cook.

Because the trash cans in the kitchen are all take-out packaging, there is nothing on the cabinets, and the white rags are as fixed as dried fish.

Da Zhao hurried over, glanced at Zhou Ning, and then put on gloves like Zhou Ning.

"Where do we start?"
