Chapter 8 Ex-boyfriend and current boyfriend

Zhou Ning was a little gloating about his misfortune. In the morning, this guy said, "You're bleeding," which made Zhou Ning feel embarrassed. Now he's fine. He's forced to do so much, and it's not an act of anger.

But it seems that the price of this car is ridiculously high.

Xu Dayuan's dagger-like gaze has fallen on Zhao Xinli.

Zhao Xinli shrunk his neck and quickly raised the picture to Xu Dayuan's eyes, but the person hid far away.

"Boss, don't be impatient. I either found it or I can't believe it. Look, it's the 2010 Nissan GT-R. The standard version of the naked car costs 1.48 million yuan. If you add up the mess, it's only 2 million yuan!

It’s not a Mercedes-Benz or BMW. It’s so expensive and others don’t understand it. It’s lonely to show off. It’s a two-door, four-seat car. It’s cramped and has such a low chassis.”

Zhao Xinli babbled for a while. As soon as Xu Da raised his hand, he stopped moving. He knew that he had fallen into his old habit.

"According to the models of these two vehicles, go to the overpass on the south side of the North Outer Ring Road to collect surveillance from all angles. If you want to drive into the North Outer Ring Road from south to north, the overpass is the only way to go. You can take a few people to go there in person.

Tell the traffic police team, don't tell me you need tomorrow."

"Don't worry, boss, I'll go right away and I'll make sure to get the surveillance camera within two hours."

Zhao Xinli stood at attention, clicking the heels of his leather shoes, and then called the criminal police and drove away in two cars.

Xu Dayuan sighed, looked at the scene, and then at the evidence bag in Zhou Ning's hand.

"Any other gains?"

"Nothing, nothing."

Zhou Ning tightened his grip on the evidence bag. He had previously thought that this thing could be sent for examination, but according to the time stamp in the forensic field book, there was no such thing at this time, and he had never heard of several of the tests above.

The principle cannot be explained either.

Xu Dayuan raised his eyebrows with curiosity on his face, and reached out to pull the evidence bag. Zhou Ning struggled twice before reluctantly letting go.

"You are so mysterious, you thought you were hiding something. What is this dark debris?"

Zhou Ning scratched his head, quickly searching for words and thinking about how to deal with it.

"This is the particulate matter extracted from the brake marks. I heard a senior student who studied chemistry say before that tires are made of natural rubber (NR), butadiene rubber (BR) and styrene-butadiene rubber (SBR) alone or in combination.

Add vulcanizing agents, accelerators, antioxidants, fillers and other organic or inorganic additives.

Each brand, each series, even tires from the same batch or the same wear state will have slightly different components extracted from the brake marks.

Analysis and comparison can be done using pyrolysis gas chromatography-mass spectrometry. I thought about asking the instructor later to see if anyone had done such an analysis. This would be an additional layer of evidence for us to identify the murderer."

Xu Dayuan, who was carrying the evidence bag, was stunned. He handed the evidence bag to Zhou Ning and patted his shoulder hard with his big hand.

"Forensic Doctor Xiao Zhou, being educated is really different. I don't understand the tests you are talking about, but I understand the meaning. That is to say, these skid marks are like fingerprints, and each one is different, right?

?”

Zhou Ning nodded.

"Don't worry, I'll find someone to ask you later. Anyway, I haven't heard of it, but it doesn't matter if I haven't. You can do it yourself!"

"ah?"

Zhou Ning was dumbfounded, Xu Dayuan waved his hand.

"Don't be so surprised. I actually know a Ph.D. from Qindao University in the city. He seems to be from the Department of Chemistry. I will help you talk about this later. It would be best if he is interested. Okay, you can go home quickly!"

test?

paper?

PhD?

As a scumbag, Zhou Ning dared to dream about these things before. He pushed up his glasses, and the damn countdown jumped to 47:28. Zhou Ning crossed his teeth and looked at Xu Dayuan.

Zhao Xinli went to check the surveillance, but he didn't know if he could find anything. Maybe he could investigate from the social relationship of the deceased. In any case, he had to complete this temporary task.

Hey, when you don't get on-site forensic medicine, you can still get by. It's more than enough to get a level 2 application without any debt. If you can't complete it and take back part of it, it will be uncomfortable. How can you go home?

"I'm not in a hurry, Xu Da. How's the social relations investigation going?"

Seeing that Zhou Ning was not in a hurry to leave, he actually smiled.

"When I was involved in my first criminal case, I was just like you. I was overly excited. I wished I could eat and live in the police force. I just wanted to catch the murderer quickly. But in this case, there is no point in rushing."

Zhou Ning was stunned. It was obvious that there was something in Xu Dayuan's words. Xu Dayuan lowered his voice.

"The autopsy report did not say that the uterine wall was thin. Based on this, we learned about it at the health school. The social relationship of the deceased Su Manli was very complicated. She had had several boyfriends, and her ex-boyfriend and her current boyfriend were also entangled."

Upon hearing this, Zhou Ning became interested.

It seems that the identities of the ex-boyfriend and current boyfriend have been found. If this is the case, wouldn't it be possible to speed up the process by checking whether they have the two models just discovered in their names?

Looking at Zhou Ning's subtle expression, Xu Dayuan didn't understand anything.

"Don't get excited. Listen to me. This ex-boyfriend is a maintenance worker in Su Manli's father's shop. He has no academic qualifications but is good-looking and has a lot of tendons. He has been taken over for interrogation.

As for this current boyfriend, his identity is a bit complicated. His mother is Yang Lihua, the chairman of Lihua Group. He takes his mother’s surname and is named Yang Yufei. It is said that he was picked up at the airport, so I asked someone to follow him to the airport."

Zhou Ning was a little dumbfounded.

"Maintenance worker? Why would Su Manli find a maintenance worker as her boyfriend? Isn't her father very rich?"

Xu Dayuan raised his eyebrows.

"You didn't see that person's appearance. Okay, don't ask so many questions. Go home and rest quickly. You'll be busy tomorrow."

Zhou Ning pursed her lips. There was no point in following him now. After all, the current boyfriend hadn't been brought back yet, and Xu Dayuan didn't even feel comfortable arresting him directly. Needless to say, his identity went without saying.

No nonsense, Zhou Ning left, Xu Dayuan asked a criminal policeman to drive him back.

As soon as he entered the courtyard door, grandpa stood in the courtyard holding the head of a broom.

Seeing this posture, Zhou Ning quickly raised his hand.

"What's wrong?"

The old man carried the broom head and walked towards Zhou Ning.

"Don't you check what time it is? Your second uncle called you several times but couldn't get through. What did you say you were doing?"

As he said that, the broom head was already hitting Zhou Ning. Zhou Ning dodged and raised his hand to catch the broom head.

"Sir, I didn't go out to play. I have a case today and I have been busy. I left my cell phone in the investigation box, so I probably have no signal."

When the old man heard this, he loosened his grip on the broom. Zhou Ning quickly placed the broom head on the low wall, which was too high for the old man to reach.

"What case? Someone died?"

Zhou Ning nodded.

"Well, the case hasn't been solved yet, so I can't say it's discipline."

In a word, the old man didn't ask any more questions. After all, my grandfather had been a village director and was very enlightened.

"Hurry and wash your hands and eat. Then call your second uncle. He has gone to your house in the city."

Upon hearing this, Zhou Ning quickly dialed his second uncle's phone number, explained a few words, and then hung up. The old man had already placed the dishes on the small table in the yard.

After Zhou Ning washed his hands, he came over, picked up his rice bowl, and started to devour the braised mackerel.

Seeing Zhou Ning looking like this, the old man helped him peel two cloves of garlic, sighed and said:

"You are a newcomer, listen more and read more. Don't think that you don't know your last name after studying for two days."

"Sir, I listen to Xu Dahe's master. After all, they have experience. However, my master had a car accident today and his leg was broken."

The old man was stunned for a moment, then showed worry on his face.

"Then go see your master and pack your things in the evening. You can go live in a house in the city. Don't run to your hometown every day. I'm worried about your safety because it's far away from work."

Zhou Ning was startled. You must know that returning to the old house every day was a request made by his grandfather before. It seemed that he felt that he was busy and was afraid that it would be too much trouble. However, thinking about the case and the countdown, Zhou Ning was a little tempted.

"Okay, I'll move over there tonight. This case is a bit tricky. Master is still injured, so I have to be on call. Don't worry, sir, I'll be back as soon as I finish the case."

The old man waved his hand and kept waving the cattail leaf fan in his hand to fan Zhou Ning.

"I am an old man, I can walk, and besides, your second uncle is here. Hurry up and eat. Your second aunt cooked the mackerel, and I left a whole one for you."

Zhou Ning smiled and Fengjuan Canyun ate the mackerel on the plate. At this moment, there was the sound of parking at the door of the courtyard, and the second uncle and second aunt walked in.

"Second uncle and second aunt, I have made you worried!"

Zhou Ning quickly got up and went to put away the dishes. The second aunt quickly took them and the second uncle laughed.

"I heard from Xu Dayuan that you performed well today."

Zhou Ning scratched his head, and the old man waved his hand.

"Don't be stunned, go pack your things and ask your second uncle to take you to live in the city."

Zhou Ning turned around and entered the house, actually taking all kinds of books with him. The house in the city had been prepared for a long time. It was the wedding room prepared by his grandfather. His parents died early, and these old men had already prepared it for him.

The second uncle is also in the county public security bureau and is in charge of logistics. He is familiar with everyone and has no great ability, but he treats Zhou Ning better than his own children.

Carrying his suitcase, Zhou Ning walked out of the main house. There was no nonsense on the way. His second uncle sent him to Yuhua Community. He took his suitcase and returned home, took a shower and lay on the bed.

This day's experience made him really tired. Less than two minutes after lying down, Zhou Ning fell asleep.

In the dream he was sitting in a windowless room with a set of seven books on the table.

The eleven huge words "Level 2 Forensic Field Study Case Analysis" above are very conspicuous. The size and thickness are daunting. No matter how hard he tries to retreat and struggle, he can't move. He can only sit down and read one page at a time.

Turn the page and look.
