Chapter 584 Leader, can I talk to you alone?

Sister Cui had a meal.

"Don't rush me. The inspection report and comparison report are all out here. They will be sent to you after printing, and then the electronic version will be sent to you."

"Okay, thank you, eldest sister."

After hanging up the phone, Da Zhao came over. He felt that Zhou Ning seemed to have something unsaid, so he swallowed it back.

"What's up, Zhou Xiaozhou? Do you want to do some experiments, but you feel embarrassed to ask? I'll do whatever you want."

Zhou Ning nodded.

"Call a few people to go to the freezer, find Liu Meiling's body, spray luminol reagent on the bruises on the deceased's neck, and videotape the whole process."

Da Zhao didn't talk nonsense, dragged Fang Mu, and the two of them went together.

After the person left, Xu Dayuan blinked and looked at Liu Yongxin. Liu Yongxin was obviously stunned, and then he sighed and said:

"Xiao Ning suspects that the DNA left on the bruise on the neck of the deceased was smeared with blood by the murderer. As for the blood dripping from the wound of the deceased, it was also left intentionally by the murderer. Of course, this makes it even more difficult to determine who the murderer is.

."

Hu Guangjian also stood up. After all, he was a front-line leader. He was quite calm and asked Xu Dayuan to go out.

Liu Yufei came over and asked with a surprised look on her face:

"The DNA was left behind on purpose, so wouldn't all our investigations be useless?"

Zhou Ning shook his head. There was very little evidence available. Xu Qingquan was inclined to identify the murderer as Zhong Xiaoyan, but the characteristics he mentioned were all revealed one by one. Scars, perfume, and Zhang Fangfang all existed. The suspects directly became two people. If the DNA and

If Zhang Fangfang matches, then Zhang Fangfang becomes the biggest suspect in this case.

At this time, Zhou Ning's cell phone rang and received a video from Da Zhao. As luminol was sprayed, a fluorescent reaction of the same shape appeared on the bruises on the neck of the deceased. Although it was very faint, this was

Bloodstains.

Zhou Ning dialed Da Zhao’s mobile phone.

"Tell Lao Yang and the others to come down and search Zhang Fangfang's car carefully to see if there are any shoes or clothes. If there is anything hidden in the trunk or in the gap of the spare tire, let me know if you find it."

Zhou Ning didn't say anything anymore. What did this order mean? Liu Yongxin understood. Peng Da and Liu Yufei looked at each other and knew what it meant. Since someone framed it, there should be something more solid, but they haven't found it yet.

After waiting for more than ten minutes, neither Xu Dayuan nor Hu Guangjian came back. Sun Gaotie came first, holding a thick stack of reports with many sticky notes on them. Zhou Ning took it and took a look.

It was quite simple. They had already been classified. Sun Gaotie kept his mouth shut and did not take the initiative to introduce him. After all, Zhou Ning hated it when someone kept nagging him while reading the report.

As he watched, the report was distributed to Liu Yongxin and others, and at the end, Zhou Ning's face showed no trace of pleasure. At this moment, Xu Dayuan came back. Seeing such a thick stack of reports, he looked directly at Zhou Ning.

"What does the report say?"

"1. The DNA of a man and a woman was extracted from the skeleton. After comparison, it is biologically related to Zhong Xiaoyan as father-daughter and mother-daughter. It has no relationship with the DNA extracted from Liu Meiling's facial wound;

1. After comparison, the DNA extracted from Liu Meiling’s facial wounds and the DNA extracted from the pinch marks on her neck were consistent with Zhang Fangfang;

2. The vitamin A, as well as related impurities and metabolites extracted from the blood in Li Li’s heart are similar to the vitamin A, as well as related impurities and metabolites extracted from Xu Qingquan’s blood sample. The impurities in Xu Qingquan’s body are greater than those in Li Li’s body.

;"

"Wait, what does this mean?"

Xu Dayuan stopped Zhou Ning, and Zhou Ning quickly explained:

"That is to say, most of the vitamin A taken by the two people is the same, but the type of vitamin A in Xu Qingquan's body may be more complex. This is also consistent with our initial judgment, the dosage of medication and the toxic dose test.

Tested on Xu Qingquan."

Xu Dayuan waved his hand towards Liu Yufei and said:

"Call the people staying at the hospital and ask them to ask Xu Qingquan whether he often ate the food cooked by Zhong Xiaoyan when he was getting along with her? Also, does Zhong Xiaoyan know how to bake? Zhou Ning, please continue."

Liu Yufei went to the side to make a phone call. Zhou Ning quickly turned to the next report and continued.

"4. Regarding the brake marks, we used gas chromatography to compare the cracked rubber and concluded that the faint brake marks fifty meters east of the accident scene were completely consistent with the brake marks of Zhang Fangfang's BMW wheel;

5. Zhang Fangfang’s DNA was found in samples No. 133 and 178 brought back from Qifeng City. Sample 133 was labeled as a sample taken from the door handle of Peppa Pig’s cabin, and sample 178 was a hair extracted from Liu Meiling’s room.”

At this point, Zhou Ning stopped, and Xu Dayuan's eyes widened.

After raising her hands and gesticulating for a long time, but saying nothing, Liu Yufei came back.

Looking at the crowd, Liu Yufei knew that during the time she was out, there were more exciting test results, so she said quickly without delay:

"Xu Qingquan said that Zhong Xiaoyan never went into the kitchen. She often ordered takeout and put it on the dinner plate, saying it was made by her. As for baking, she didn't know how to do it. But among the people she knew, Zhang Fangfang was a chef.

Art is the best.

In addition, I just received news that from noon on August 31st to the afternoon of September 2nd, Zhang Fangfang was in Qindao. She attended a wedding and was Zhang Fangfang’s cousin. However, her parents did not come back. The wedding was in September.

On the 1st, photos showed that it was the BMW she drove back to Qinqin this time."

Several people were a little dumbfounded, and they went back and forth, and now Zhang Fangfang became an important suspect. At this time, Zhou Ning's cell phone rang, and Da Zhao sent a video call application, and Zhou Ning clicked to connect.

"Zhou Xiaozhou, we dismantled Zhang Fangfang's BMW, inspected all the cracks in the wheels and extracted sand and gravel. We took apart the spare tire baffle in the trunk. There was no spare tire inside, only two huge garbage bags. Let me take a look at it.

, there’s everything in here, including shoes, gray cleaning clothes, rubber gloves, a fire spray gun, and a dagger.”

As he said that, Da Zhao used long tweezers to lift up the dagger. The black and purple blood stains on it were too conspicuous. You don't need to introduce them to know what they are.

"Make a good mark and send it for inspection. I'll go down and take a look now. The driver's steering wheel must be carefully collected to make sure there are no omissions."

"I understand, I have asked people to use tape to extract these locations on the steering wheel, gear knob, seats, keys, and door handles. I am afraid of any omissions. They say that any contact will leave traces. I was stuck this time.

."

Zhou Ning hung up the phone and glanced at Xu Dayuan.

"Leader, can I talk to you alone?"

"Let's go down and take a look at Zhang Fangfang's car. We did neglect to inspect the car."

The two walked downstairs and came to the backyard. They did not approach the busy Da Zhao and others. Zhou Ning handed Xu Dayuan a cigarette, and the two lit it, but did not speak for a long time.

After a while, Xu Dayuan sighed.

"Are you feeling uncomfortable?"

"Yes, I found out about Shi Yun's experience and the cause of death of Shi Mingchen's family. I was angry. I thought about what I would do if it were me. I thought about it for a long time and brought it from a girl's perspective. I think I

Not necessarily Shi Yun does it well.

But now that the case has been investigated and all the evidence points to Zhang Fangfang, I am confused. Maybe Shi Yun also hates the police. If someone asked or the police intervened back then, the outcome might be different. But even if the news broke,

There was no police intervention.

You saw the video that Da Zhao just sent. I'm sure that the things found in the trunk have Zhang Fangfang's fingerprints and Zhang Fangfang's DNA. Now that she has become the first suspect, what should we do?"

Xu Dayuan took two strong puffs, threw the cigarette butt on the ground, and smiled at Zhou Ning.

"Remember, we are just police officers, not judges, and we are not lone heroes. We do our best to investigate, correct our mentality, and present all the evidence. This is what we should do. As for how to judge this case, that is not us.

If you’re worried, let me ask you something: when you learned about Shi Yun’s experience, did you have the urge not to investigate?”

Zhou Ning was silent for a long time before he raised his head and nodded slightly towards Xu Dayuan.

"Yes, at that time I felt that I didn't want to investigate, I didn't want Shi Yun to be caught, I didn't want her to leave traces, but..."

Xu Dayuan patted Zhou Ning on the shoulder.

"No, just do whatever you want to investigate. You go and see Da Zhao and the others. I'll go upstairs and talk to Zhang Fangfang. Since I've found new physical evidence, there's no need to talk to Zhong Xiaoyan in depth. I'll get off work early after the investigation. Everything

Waiting for the results.”

A few words seemed to give Zhou Ning some direction. Without much greeting, he walked straight towards Da Zhao and the others.

"Is the survey completed?"

Da Zhao nodded.

"This car has been inspected before, but it was not so detailed. At that time, only Zhang Fangfang's fingerprints were found on the steering wheel and driver's seat. After the DNA comparison was sent for inspection, because this was not important, we did not take pictures of the front.

, so no results came out this time.

But I really didn’t expect that the murder weapon, clothing, gloves, etc., could appear in the spare tire box of the vehicle. If Zhang Fangfang hadn’t been wearing it, how could Zhang Fangfang’s DNA be left on it?”

Zhou Ning shook his head.

"I don't know. I still can't figure out the process now. I'm going to find Xiaoqu to see if there are any new findings in the monitoring analysis. You can get off work after sending it for inspection."

Da Zhao grabbed Zhou Ning's arm, moved towards the direction Xu Dayuan left, and asked in a low voice:

"What does the leader mean? He must let us find the DNA left by Zhong Xiaoyan?"

Zhou Ning shook his head.

"The leader said that we should do what we should do. Judgment and conviction are matters for the court. I think it makes sense. Don't conduct investigations based on our subjective wishes. This is biased. Stop talking nonsense and get to work."

Da Zhao shrugged and let go of Zhou Ning's arm. Zhou Ning quickly came to the laboratory. Some samples have been sent here. After all, Peng Shinian is the most professional in the analysis of gravel and seeds.

Seeing the busy little song, Zhou Ning walked over.

"How's it going? Are there any new findings from the surveillance?"

Xiaoqu raised a bitter face, looking like he was going crazy.

"Boss, I found Zhang Fangfang's car. After the car accident, it was driving in the opposite direction to the west. After getting on the Huanwan Expressway, it got off at the Shuangbu Expressway intersection. After tracking it south for a few kilometers, it disappeared.
