Chapter 8 Ex-boyfriend and current boyfriend
Zhou Ning was gloating on the side. This guy had made Zhou Ning so embarrassed in the morning by saying "you are fainting from blood". Now, he is complaining so much and adding fuel to the fire.
But it seems that the price of this car is ridiculously high.
Xu Da's sharp gaze had already fallen on Zhao Xinli.
Zhao Xinli shrank his neck, bared his teeth, and quickly raised the picture in front of Xu Dayuan, but he hid far away.
"Don't be so angry, boss. I found it, but it's a little hard to believe. Look, it's the 2010 Nissan GT-R. The price of the bare car standard version is 1.48 million yuan. Add up all the other stuff, and it's almost 2 million yuan!
It's not a Mercedes-Benz or BMW. If it's so expensive, people won't understand it. It's just showing off. It's also a two-door, four-seater car. It's very crowded and has a low chassis."
Zhao Xinli kept muttering to himself, but when Xu Dayuan raised his hand, he suddenly stopped moving. He knew that his old problem had come back.
"According to the models of these two vehicles, go to the overpass on the south side of the North Outer Ring Road to retrieve surveillance footage from all angles. If you want to drive onto the North Outer Ring Road from south to north, you must pass through the overpass. Take a few people with you and tell the traffic police team. Don't tell me you need it tomorrow."
"Don't worry, boss. I'll go right away and make sure I get the surveillance footage within two hours."
Zhao Xinli stood at attention, the heels of his leather shoes tapping loudly, then he called the criminal police and drove away in two cars.
Xu Dayuan sighed, looked at the scene, and then looked at the evidence bag in Zhou Ning's hand.
"Anything else you gained?"
“Nothing…Nothing…”
Zhou Ning clenched the evidence bag tightly. He had thought that he could send this thing for inspection, but according to the time markings in the book on forensic scene science, there was no such thing at this time. He had never heard of the experiments in it, and he couldn't explain the principles.
Xu Dayuan raised his eyebrows, with a look of curiosity on his face, and reached out to grab the evidence bag. Zhou Ning struggled for a few times before letting go reluctantly.
"You are so mysterious, I thought you were hiding something. What is this black debris?"
Zhou Ning scratched his head, his mind quickly searching for words, thinking about how to respond.
"These are particles extracted from brake marks. I heard from a senior student who studies chemistry that tires are made of natural rubber (NR), butadiene rubber (BR) and styrene butadiene rubber (SBR) alone or in combination, with the addition of vulcanizers, accelerators, antioxidants, fillers and other organic or inorganic additives.
The components extracted from the brake marks of each brand and series, even tires that are not from the same batch or in the same state of wear, will be slightly different.
We can use pyrolysis gas chromatography-mass spectrometry to analyze and compare. I'm thinking of asking my mentor if anyone has done such an analysis before. This will give us another piece of evidence to help us identify the murderer."
Xu Dayuan, who was holding the evidence bag, was stunned. He handed the bag to Zhou Ning and patted him on the shoulder with his big hand.
"Xiao Zhou, forensic doctor, being educated is really different. I don't understand the tests you mentioned, but I understand your meaning. That is, these brake marks are like fingerprints. They are all different, right?"
Zhou Ning nodded.
"Don't worry, I'll ask someone for you later. Anyway, I haven't heard of it. But it doesn't matter if there really isn't one. Just figure it out yourself!"
"ah?"
Zhou Ning was dumbfounded and Xu Dayuan waved his hands.
"Don't be so surprised. I do know a doctor from Qindao University in the city. He seems to be in the Department of Chemistry. I will talk to you about this matter later. It would be great if he is interested. Now, go home quickly!"
test?
paper?
PhD?
As a poor student, Zhou Ning had never dared to dream about these things before. He pushed up his glasses, and the damn countdown jumped to 47:28. Zhou Ning gritted his teeth and looked at Xu Dayuan.
Zhao Xinli went to check the surveillance footage, but he didn't know if he would find anything. Perhaps he could investigate the deceased's social relationships. He had to complete this temporary task no matter what.
Alas, when I didn't have to study on-site forensic medicine, I could still get by. If I wasn't impatient, I could get a second-level application, which was more than enough. If I couldn't complete it and took back part of it, I would be very upset. How could I go home?
"I'm not in a hurry, Xu Da. By the way, how's the social relationship investigation going?"
Seeing that Zhou Ning was not in a hurry to leave, he smiled.
"When I was dealing with my first criminal case, I was just like you. I was too excited and wanted to live and eat in the police force. I just wanted to catch the murderer as soon as possible, but there was no point in being anxious in this case."
Zhou Ning was stunned. It was obvious that Xu Dayuan had something else to say, so he lowered his voice.
" The autopsy report did not say that the uterine wall was thin. Based on this, we learned from the side of the medical school that the deceased Su Manli had complicated social relationships. She had dated several boyfriends, and her ex-boyfriend and current boyfriend were also entangled."
Upon hearing this, Zhou Ning became interested.
It seems that the identities of the ex-boyfriend and the current boyfriend have been found . If so, wouldn’t it be possible to speed up the process by checking whether they have the two car models that have just been discovered under their names?
Looking at Zhou Ning's subtle expression, Xu Dayuan had something in mind that he didn't understand.
"Don't get excited, listen to me. This ex-boyfriend is a maintenance worker in Su Manli's father's shop. He has no education but looks good and has a muscular body. He has been taken away 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, Yang Yufei. It is said that someone went to the airport to pick him up. I asked someone to follow him to the airport. "
Zhou Ning was a little speechless.
"Maintenance worker? Why would Su Manli choose a maintenance worker as her boyfriend? Isn't her father very rich?"
Xu Dayuan raised an eyebrow.
"You didn't see what that person looked like. Okay, stop asking so many questions. Go home and have a rest. You'll be busy tomorrow."
Zhou Ning pursed her lips. There was no point in following her now. After all, her current boyfriend had not been brought back yet. Xu Dayuan even felt it was not appropriate to arrest him directly, not to mention his identity.
Without any nonsense, Zhou Ning left, and Xu Dayuan asked a criminal policeman to drive him back.
As soon as I entered the yard, I saw my grandfather standing in the yard holding a broom.
Seeing this, Zhou Ning quickly raised his hand.
"What's wrong, sir?"
The old man walked towards Zhou Ning holding a broom.
"Don't you see what time it is? Your second uncle called you several times but couldn't get through. Where have you been?"
As he spoke, the broom head came towards Zhou Ning. Zhou Ning dodged and raised his hand to catch the broom head.
"I didn't go out to play. I had a case today and was busy. My phone was left in the investigation box, so I guess there's 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's dead?"
Zhou Ning nodded.
"Well, the case hasn't been solved yet. I can't say it's disciplinary."
In one sentence, the old man did not ask any more questions. After all, his grandfather had been the village director and he had a high level of awareness.
"Hurry up and wash your hands and eat. Then give your second uncle a call. He's at your house in the city."
When Zhou Ning heard this, he quickly called his second uncle, told him a few words, and then hung up. The old man had already placed the dishes on the small table in the yard.
After washing his hands, Zhou Ning came over, picked up the bowl, and started to wolf down the braised Spanish mackerel.
Seeing Zhou Ning eating like this, the old man helped him peel two cloves of garlic, sighed and said:
"You are a newcomer, so listen and watch more. Don't think that you don't know your last name because you have studied for two days."
"Master, I always listen to Master Xu and Master. After all, they have experience. But my master had a car accident today and his leg was fractured."
The old man was stunned, then his face showed worry.
"Then go see your master. Pack up your things at night and move to the house in the city. Don't go back to your hometown every day. I'm worried about your safety because your work is far away."
Zhou Ning was stunned. You know, returning to the old house every day was his grandfather's previous request. It seemed that he felt he was busy and was afraid that it would be too much trouble. But thinking about the case and the countdown, Zhou Ning became tempted.
"Okay, I'll move over tonight. This case is a bit tricky, and my master is injured, so I have to be there whenever you call. Don't worry, I'll be back after I finish the case."
The old man waved his hands and waved the palm-leaf fan in his hand continuously, fanning Zhou Ning.
"I'm an old man, but I can still walk. Besides, your uncle is here. Come and eat. Your aunt cooked Spanish mackerel, and I left a whole one for you."
Zhou Ning smiled and ate the Spanish mackerel on the plate in no time. At this moment, the sound of a car stopping was heard at the gate of the yard, and his second uncle and second aunt walked in.
"Uncle and aunt, I'm sorry to have made you worried!"
Zhou Ning quickly stood up and went to clean up the dishes. Second Aunt quickly took over and 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 just stand there, go pack your things and ask your uncle to send you to live in the city."
Zhou Ning turned around and went into the house, actually he just took various books with him. The house in the city had been prepared long ago. It was the wedding house prepared for him by his grandfather. His parents died early, so these things had been prepared for him by the old man.
The second uncle is also in the County Public Security Bureau, in charge of logistics. He is familiar with everyone and does not have any great abilities, but he treats Zhou Ning better than his own children.
Carrying the 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 returned home with the luggage, took a shower and lay down on the bed.
The experiences of the day 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 characters on it, "Second-level Forensic On-site Case Analysis", were very conspicuous. The size and thickness were daunting. No matter how he wanted to retreat and struggle, he could not move. He could only sit down and read one page after another.
Case number one……
