Chapter 147 What is the picture?

Waiting is torture.

Zhou Ning glanced at his watch. It was already 5:10 in the afternoon, and he was about to leave work, but there was no news from the laboratory.

On the claw hammer, as Liu Yongxin guessed, there were no fingerprints left at all, but this is not a new hammer, there are some gray and black things left in the gap, but the naked eye cannot find out what it is.

At this moment, the door of the office was pushed open.

Xu Dayuan walked in and saw Zhou Ning asking anxiously:

"Found the murder weapon?"

"Well, a claw hammer has already been sent to the laboratory. Sister Cui said to give me the test results before get off work. I asked her not only to test the blood, but also to extract all the substances that can be extracted from the hammer."

Xu Dayuan nodded. Seeing mineral water on the table, he turned it open and drank a bottle. He also stood under the air conditioner. After all, the weather in Qindao was extremely hot these two days, and the sticky feeling before the heavy rain made people Extremely uncomfortable.

Liu Yongxin was drinking tea, shaking his legs and looking at Xu Dayuan, who was full of lawsuits.

"I said, why are you so impatient? Don't be so impatient. Sit down and talk about it. What's wrong with the young couple? Did Sun Yannian admit that he had been to the scene?"

Xu Dayuan kicked Big Zhao to make room for him to sit on the chair.

"Admittedly, you have processed the video and compared the photos. It's useless if he doesn't admit it, but he said that he just wanted to go for a drive. The fog was too thick and he didn't notice that there was a car accident in front of him. He touched it and ran back quickly.

He also bumped into the wall in the garage, thinking that after two days, after his father's affairs were settled, he would find the insurance company to repair the car. He said that although the car was under Yu Meili's name, the house and the car were all They are using it, and it is also his father's property. If it is broken, it will not hinder other people's business. "

"Heh, the mouth stinks enough!"

"Yes, such a young man with a rebellious spirit, I really want to give him two mouths. As for the relationship with Wang Mengmeng, he said that Wang Mengmeng seduced him, and he took the initiative to sacrifice himself.

Wang Mengmeng was very good at hooking up boys at school. On the surface, she looked like a good girl, but she was actually very good at these things. When I went out for a drive with him, the two of them had a game in the car. Using Sun Yannian's words to describe her, she was very experienced. As for The relationship between adults has nothing to do with them. "

Zhou Ning didn't speak, but frowned.

"When his biological father died, he was still so indifferent. He was thinking about repairing the car and inheriting the property in the future. This sounds strange, and it is reasonable to go for a drive anywhere. He went for a drive from No. 102 in Dongtai District to Jingkou. This is a bit too coincidental, I think he is hiding something."

Xu Dayuan snapped his fingers and looked at Zhou Ning with satisfaction.

"Zhou Xiaozhou is the same as I think, but don't worry. This kid forged his documents and drove without a license. There is nothing wrong with being locked up for a few days. Let him calm down first, and it won't be too late for him to be interrogated later."

Just as she was talking, Cui Lili opened the door and came in, with the same expression on her face that no strangers should enter. She walked up to everyone and handed a few pieces of paper to Zhou Ning.

"The blood of the deceased was extracted from the head of the claw hammer you sent over. As for the gap between the hammer head and the handle, as well as a lot of substances found on the handle, after analysis, it should be grease, gravel, cement, asphalt, etc. .

There is a gap in the wooden handle of the claw hammer, and a bunch of fibers are sandwiched in it. We analyze it and think it is a cotton glove. This has been taken out and DNA extraction is carried out. However, the probability of this is the same as winning the lottery. Don’t give too much hope. We Will extract several times. "

Zhou Ning nodded. He understands this. It is indeed as Cui Lili said. Finding DNA on a cluster of fibers is similar to finding a needle in a haystack. You can't point at this, but you still have to work hard.

"Thank you, Sister Cui. I know it's not easy to extract, but let's do it a few more times. After all, there are no more clues in this case. Besides, have you extracted the nail samples submitted by Wang Wenjing and Chen?"

Cui Lili shook her head, frowning.

"I'm in a hurry to extract the claw hammer, and I don't have time to do anything else. However, we all work overtime and try to get out at night. Tell me what tests you need?"

"Poison, and DNA testing."

"it is good!"

Seeing that Cui Lili was about to leave, Da Zhao quickly opened the door and sent her out politely.

"Miss Cui has worked hard. The case is a little urgent. Zhou Xiaozhou can't comfort people. He just talks about the inspection. Please take care of him!"

Cui Lili didn't say anything, but she left with a smile on her lips. Xu Dayuan patted his legs and stood up.

"Okay, it's useless to waste time, everyone get off work, wait for other tests to come out, tell me quickly, I will meet this Sun Yannian after I have something to eat."

Both Liu Yongxin and Zhou Ning stood up, Da Zhao even opened the door, only Xia Momo didn't move, Xu Dayuan couldn't hold back when he saw the three of them making gestures to see off the guests.

"I said, you don't have any sympathy?"

Zhou Ning paused for a while, unable to understand what Xu Dayuan meant by this, did he do something too much?
Big Zhao leaned over with a hippie smile, put his arms around Xu Dayuan and said:
"I said Xu Da, what do you want us to do? Do you still want to apply and accompany you to the trial? Uncle Liu has retired and is now a person in the laboratory, especially Teacher Xia.

As for me and Zhou Xiaozhou, I have been with you for a whole morning, went to Wang Wenjing's house and Chai Ruhua's house, from sampling to vehicles, and even Zhou Xiaozhou went to check Chen Chunxi's car in the afternoon, which made us a little nervous. Sympathy? "

Xu Dayuan raised his leg, but Da Zhao was prepared and jumped away.

This is where Da Zhao's EQ is high. These are clearly speaking for Zhou Ning, but in fact they are also helping Xu Dayuan to explain that he absolutely values ​​Zhou Ning and needs his help, not an ordinary leader giving orders.

"As far as you talk a lot, Zhou Xiaozhou observes the problem from a very different angle, and can surprise me every time. You are quite old men, don't tell me you want me to say something nasty, go and treat you to a boxed lunch."

Several people laughed, and Liu Yongxin folded his arms.

"You go, my wife will take me to see the house."

Zhou Ning paused, the master and his wife have both retired, and now they live in the dormitory of Qindao University.

"Is your son getting married?"

Liu Yongxin shook his head.

"A friend moved his family to the south, and the house needs to be dealt with. After all, the price is very beautiful. I will go and see if it suits me, and I will stay. Anyway, I don't want to prepare a house for him in Qidong."

Xu Dayuan waved his hand.

"Then go, it's a big deal, do you need me to find someone to take you there?"

Liu Yongxin shook his head.

"Don't accommodate me, my apprentice has been ordered by you, why don't you pretend to be polite with me, let's go!"

After Liu Yongxin went out first, Xu Dayuan rubbed his nose and sighed.

"I found out that no one can offend anyone now. When Lao Liu was in Qidong, we cooperated well. Now he is regarded as the laboratory staff of Qindao University, and he suddenly became a landlord. It's just you two and I can yell twice, it's hard!"

Zhao Xinli put his arm on Xu Dayuan's shoulder, patted and said:
"Leader, work hard. We are waiting for you to become the chief. At that time, you can yell whoever you want."

Xu Dayuan avoided Zhao Xinli's claws and went downstairs side by side with Zhou Ning.

"Tell me about your sixth sense. Who put this claw hammer?"

Zhou Ning looked bitter.

"Xu Da, I'm not a fortune teller. Where can I guess? But I think that the deceased was poisoned for a long time, which is related to this car accident. By the way, have you checked Zhang Guanglei's account? Has there been any transfer of funds recently?" ?”

"I checked this earlier, not only Zhang Guanglei, but also Sun Manqing. Zhang Guanglei has more than 17 in his account, and there is no change. As for the real estate, he hasn't sold it. The people in his unit don't know much about his girlfriend. It seems that he is not a person who likes to talk about personal matters."

Da Zhao leaned over, stretched his head and said:

"I also don't understand this. Why is he looking for Wang Wenjing? He is old and has a daughter, or is he not good? And if he finds it, he doesn't tell his colleagues, and the other party regards him as an ex-boyfriend and has a new love .

As for him, no one moved his savings, no one cared about his house, he was an employee of the Water Conservancy Bureau, he was not a big leader, and he had no vested interests around him, so why did he kill him?Oh, by the way, he has been poisoned for a long time, what is the plan? "

Xu Dayuan stopped in his footsteps, and Da Zhao subconsciously jumped to Zhou Ning's side, his face full of vigilance.

"Leader, let's talk about something. Your surprise is a bit scary."

Xu Dayuan didn't do anything, but glanced at Da Zhao.

"You're right. I've always been puzzled by this point. She looks average, has an average job, and has an average relationship. It's just an old woman who is not here, and her ex-wife is even richer and more beautiful. She doesn't look like a girl. As for the victim, it seems that the investigation of Wang Wenjing will go deeper."

Zhou Ning nodded slightly. The timing of Wang Wenjing's injury was too critical. This injury directly cleared her suspicion. She may have been with such an ordinary person like Zhang Guanglei for more than two years. It was during this period that Zhang Guanglei was poisoned. Perhaps What have they overlooked.

"Zhou Xiaozhou, what did you think of?"

Xu Dayuan looked at Zhou Ning with hope, and Zhou Ning glanced at him.

"After dating for more than two years, Zhang Guanglei and Wang Wenjing's daughter will also meet each other, right? Didn't you just say that Sun Yannian said that it was Wang Mengmeng who seduced him?"

Xu Dayuan paused and took out his phone.
