Chapter 150 A Figure

"Who?"

"Sun Manqing, Zhang Guanglei and Sun Manqing had dinner together. 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 they seemed to have chatted for a while. After eating in a hurry, the two left one after another.

However, from another monitoring angle, it seems that there is a man who has been following Zhang Guanglei, but the man is wearing a hat and cannot see his face clearly. The surveillance video has been sent to your email. "

Zhou Ning heard the phone ding-dong, and quickly clicked on it. The two videos he received were obviously intercepted.

When Sun Manqing and Zhang Guanglei met, there was no tension. Zhang Guanglei was not very polite about the money Sun Manqing paid. Sure enough, when the two got up, a man quickly followed him from the corner.

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

However, Zhang Guanglei and Sun Manqing had breakfast together, which seemed unbelievable. Zhou Ning's eyes were attracted by the person in the corner of the video.

Da Zhao quickly clicked on another surveillance clip, this angle could be better than that one, the man in the corner followed Zhang Guanglei towards the side of the road, and when he turned his head in the direction of the surveillance, he raised his hand to hold his hat.

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

"Are you wearing a wig? The characteristics of this finger are consistent with Chen Chunxi's. It seems that when I searched his car this morning, I still overlooked some details."

Da Zhao rolled his eyes.

"What do you want to do, really think that you are a fortune teller, and you can know who the murderer is when you turn the compass? You don't want to curl up here, so as not to let people live? But this hair doesn't look fake to me. Yes, probably in order to change the appearance and not attract others' attention, so I cut my hair yesterday."

Zhou Ning agreed with this analysis, but according to this line of thinking, Chen Chunxi wanted to kill Zhang Guanglei, which made no sense, especially that Wang Mengmeng was obviously helping Chen Chunxi, and they completely used Sun Yannian as a scapegoat.

Those conversations just now, as well as the various related records, are all calculated and properly posted. This level of meticulousness is really not easy, and it also makes the criminal police team toss around.

So, why can Chen Chunxi cooperate with Wang Mengmeng?
In order to prove that he was not there, Wang Wenjing beat herself to pieces. What is the reason for this?
Zhou Ning paused, and the word Dalong popped up in his mind, and he stood up directly.

Zhang Guanglei is introverted, not good at speaking, even out of gregariousness, and does not like to socialize. There is a big gap between him and Meili, and then he gets together with Wang Wenjing.

Wang Wenjing's mother was against it. As for Wang Mengmeng's attitude, it was even more telling, but they persisted for more than two years, and Zhang Guanglei's poisoning had also lasted for more than a year. Could it be that Zhang Guanglei had been pestering Wang Wenjing all the time.

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

It would be better if it was a car accident, and the insurance would pay a lot of compensation. If it was not a car accident, at least Sun Yannian would be responsible.

However, there was a variable here, that is, Zhou Ning followed to help.

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

"I'm Zhou Ning!"

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

In addition, on the fiber extracted from the claw hammer, we were lucky to find a male DNA. After comparison, it was consistent with Chen Chunxi who had been submitted for inspection before. Can our laboratory be off work? "

Zhou Ning was extremely embarrassed. Although Cui Lili's attitude was still icy, she was a worker, and she didn't have to please anyone. Let her work overtime, which was good enough.

"Thank you, Sister Cui, you guys hurry up and get off work, I won't be sent for inspection today!"

Da Zhao gasped, feeling so excited that he didn't know what to do.

"Zhou Xiaozhou, we don't have a report at hand, let me get it?"

Just as he was talking, Zhou Ning's cell phone rang again, and then he received the email for the test. Da Zhao ran out with a smile. He didn't need to be told, he knew where to print it.

Zhou Ning patted his chest and pushed the call button.

"Xu Da, please come out, there are feedbacks from various investigation results, we guessed it right!"

Zhou Ning's guess was right, Xu Dayuan raised his eyebrows unconsciously, stood up and handed the tissue to Chen Chunxi.

"You guys control your emotions first, we will continue later."

After speaking, Xu Dayuan came out quickly, followed by the clerk. Only Chen Chunxi and Wang Mengmeng were left in the huge interrogation room. Wang Mengmeng still lowered her head, but she reached out her hand in front of Chen Chunxi and took out a tissue.

At the same time, there was an exchange of eyes with Chen Chunxi, Chen Chunxi pursed his lips, the comforting look disappeared from his face, and there was a hint of warning in his eyes, Wang Mengmeng quickly covered his face with a tissue.

This series of movements, if you don't look carefully, you can't find it at all, but Da Zhao didn't blink, and took this scene into his eyes.

"Chen Chunxi is warning Wang Mengmeng. He seems to be extremely dissatisfied with Wang Mengmeng's performance. Have you seen it? Have you seen it? I think they must have rehearsed before, maybe after analyzing the possible situation, but now it is beyond their expectations."

Xu Dayuan glanced inside the one-sided glass, and gave Da Zhao a blank look. This guy's babbling is really annoying.

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

Zhou Ning quickly said two phone calls and test results, and Xu Dayuan heard it with obvious surprise on his face.

"Zhang Guanglei and Sun Manqing had breakfast together, and they met by chance. This is quite 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?"

Both Zhou Ning and Da Zhao shook their heads, 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 that Xiao Zeng sent before, opened it and looked at it.

"Yesterday Xiao Zeng retrieved their call records. At 7:44, Sun Manqing received a call from Yu Meili. This 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 following Zhang Guanglei. This person is gone, so I want to follow up and have a look."

Zhou Ning nodded. From the video, Sun Manqing glanced in Zhang Guanglei's direction after seeing Zhang Guanglei leave, then answered a call and was delayed for 2 minutes before walking towards the side of the road until he was out of the surveillance range.

"Although the Dalong remaining in Wang Wenjing's nails can be used as evidence that she poisoned Zhang Guanglei, I still want to check Zhang Guanglei's house. Wang Wenjing must have done it very secretly after poisoning for such a long time. If they find this, I don't think they will be fine. It’s so good to hide.”

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

"I won't say any more polite words. I will start the interrogation of Chen Chunxi immediately. If you have any news, please call me."

Da Zhao also stood up and came over.

"I'll go with you, we have too few trace tests, it's not enough."

Zhou Ning shook his head. It is true that there is a shortage of people. What is lacking is people who work. There are a lot of trace inspections in the technical department of the Municipal Bureau, including old, middle and young people, but not many people really put their minds on the case, especially criminals. The case was originally a weak point of the Municipal Bureau, and it was a little difficult, so I wanted to find an expert from the province.

"We went."

After finishing speaking, Zhou Ning dragged Da Zhao out, Xiao Zeng ran out from nowhere, and hurried over when he saw the two of them.

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

Zhou Ning nodded, they didn't talk nonsense, and quickly got into the car and arrived at Zhang Guanglei's house.

There was a policeman staying at the door, and he opened the door to enter. There was a musty smell in the room. It seemed that the deceased was not a very clean person. Turn on the light and look in the room. The cleanest place is probably the kitchen. You can tell that Zhang Guanglei Hardly any cooking.

Because the trash can in the kitchen is full of takeaway packaging, there is nothing on the cabinets, and the white dishcloths are as stereotyped as dried fish.

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

"Where do we start?"
