Chapter 8, Ex-boyfriend and Current Boyfriend

Zhou Ning pressed her lips tightly together; at this moment, it was meaningless to follow along, after all, that current boyfriend had not yet been brought back. Xu Dayuan felt it was inappropriate to directly apprehend someone, and there was no need to elaborate on that identity

In the dream, he sits in a room without windows, where a set of seven books is placed on the table

You little rascal, acting all mysterious, I thought you were hiding something. What is this dark, crumbly stuff?

Aren't you going to check what time it is? Your second uncle has called you several times, but he couldn't get through. What have you been up to?

Zhou Ning quickly got up to tidy up the dishes and chopsticks, while the second aunt hurriedly took over, and the second uncle laughed.

Boss, rest assured, I will go right away and guarantee to obtain the surveillance footage within two hours

Zhou Ning was taken aback, clearly sensing that Xu Dayuan's words carried deeper meaning, as Xu Dayuan lowered his voice

Zhou Ning smiled, and the wind swept away the remnants of the clouds, consuming the mackerel on the plate. At that moment, the sound of a car parking came from the courtyard entrance, and Uncle Er and Aunt Er walked in.

The old man approached Zhou Ning while holding a broomstick

It is not like a Mercedes-Benz or a BMW, why is it so expensive? Others do not understand, it is just a lonely display, and it is still a two-door four-seater, cramped and crowded, with such a low chassis

Hurry and wash your hands to eat, and then give your second uncle a call; he has gone to your house in the city

Seeing Zhou Ning eat in such a manner, the old man helped him peel two cloves of garlic and sighed as he spoke

I heard Xu Dayuan say that you performed quite well today

Ah, even when I don't get to learn at the forensic scene, I can still get by. As long as I don't overreach, obtaining a secondary application would be more than sufficient. If I fail to complete this, and some of it is taken back, that would be quite distressing. How could I possibly go home

Experiment

It seems that the ex-boyfriend and the current boyfriend have identified themselves. If that is the case, wouldn't checking whether they have the two recently discovered car models under their names expedite the process?

The second uncle also works at the county public security bureau, responsible for logistics. He is familiar with everyone and lacks significant abilities, but he treats Zhou Ning better than his own children

I, an old man, am able to walk and move about. Moreover, your second uncle is here, so hurry up and eat. Your second aunt has cooked mackerel, and I saved an entire one for you

thesis

As he spoke, the broomstick head was already coming towards Zhou Ning. Zhou Ning swiftly dodged and raised his hand to catch the broomstick head

Observing Zhou Ning's subtle expressions, Xu Dayuan understood everything.

Upon hearing this, Zhou Ning became interested

There is no need to be so surprised, I happen to know a doctor with a doctorate from Qindao University in the city, who seems to be from the Chemistry Department. I will talk to him about this matter; it would be best if he is interested. Alright, you should hurry home now

What case? Is someone dead?

Xu Dayuan, holding the evidence bag, was taken aback. He handed the evidence bag to Zhou Ning and forcefully patted him on the shoulder.

The old man did not pursue the matter further, after all, grandfather had served as the village head and had a high level of awareness

Do not rush, I will ask someone for you later. Anyway, I have not heard of it, but if it really does not exist, it is not a big deal. You can handle it yourself

Zhou Ning was taken aback, for it was known that returning to the old house every day was a request made by his grandfather. It seemed that he felt busy and was afraid that this would be too much trouble. However, thinking about the case and that countdown, Zhou Ning felt somewhat tempted

When I was dealing with my first criminal case, I was just like you, overly excited, wanting to eat and live in the police station, eager to catch the murderer as soon as possible, but being anxious about this case was of no use

Uncle and Aunt, I have caused you worry!

Each brand and each series, even those from different batches or with varying degrees of wear, will exhibit slight differences in the components extracted from the brake marks

What happened, Grandpa

You did not see that person's appearance, enough, do not ask so many questions, hurry home to rest, there will be much to do tomorrow

Do not get excited, let me finish speaking. This ex-boyfriend is a repairman at Su Manli's father's shop. He has little education but is quite good-looking and has a muscular build. The person has already been taken in for questioning.

As for this current boyfriend, his identity is somewhat complex. His mother is Yang Lihua, the chairwoman of Lihua Group. He takes his mother's surname and is named Yang Yufei. It is said that he went to the airport to pick someone up, and I had someone follow him to the airport

No... nothing...

Boss, don't be too anxious. I have found it, but it's somewhat hard to believe. Look, it's this Nissan GT-R 2010 model, the base price for the bare car is 1.48 million yuan, and with all the additional costs, it comes to nearly 2 million yuan!

The old gentleman waved his hand, continuously fanning with the palm-leaf fan in his hand, creating a breeze for Zhou Ning

Zhou Ning nodded

Zhou Ning stood to the side, somewhat gloating. This morning, when this person said, "You faint at the sight of blood," it made Zhou Ning feel extremely embarrassed. Now, with so much fuss and chatter, isn't it just adding fuel to the fire

Zhou Ning was somewhat speechless

As a poor student, these were things that Zhou Ning had never dared to imagine before. He pushed up his glasses, and the damned countdown jumped to 47:28 at that moment. Zhou Ning gritted his teeth and looked at Xu Dayuan.

The old man was taken aback, and then a look of concern appeared on his face

Xu Dayuan raised an eyebrow

The autopsy report does not indicate that the uterine wall is thin. Based on this, we inquired at the health school and learned that the deceased, Su Manli, had a very complicated social relationship, having had several boyfriends, with entanglements between her ex-boyfriend and current boyfriend.

As soon as I entered the yard, my grandfather was standing inside with a broom in hand

Do not just stand there, go pack your things, and have your second uncle take you to live in the city

Zhao Xinli stood at attention, the heels of his leather shoes making a sharp sound as they struck the ground, and then he called for the criminal police to drive away in two vehicles.

Carrying his suitcase, Zhou Ning walked out of the main house, without exchanging any words along the way. His second uncle accompanied him to Yuhua Community, and he returned home pulling his suitcase, took a shower, and then lay down on the bed

Zhao Xinli went to check the surveillance footage, uncertain if any discoveries could be made. Perhaps an investigation could be conducted based on the deceased's social relationships. Regardless, this temporary task must be completed

Ah?

The experiences of this day left him quite exhausted, and within less than two minutes of lying down, Zhou Ning fell into a deep sleep

Zhou Ning, after washing his hands, leaned over, picked up the rice bowl, and began to devour the braised mackerel voraciously.

Zhou Ning scratched his head, his mind racing to find the right words, contemplating how to respond

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

Xu Dayuan's piercing gaze, sharp as a knife, has already settled on Zhao Xinli

These are the particulate matters extracted from the brake marks. I previously heard from a senior who studied chemistry that tires are made from a single or blended rubber of natural rubber (NR), polybutadiene rubber (BR), and styrene-butadiene rubber (SBR), while also incorporating vulcanizing agents, accelerators, anti-aging agents, fillers, and other organic or inorganic additives

However, it seems that the price of this car is exorbitantly high

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

Then go see your master, pack your things in the evening, and stay at the house in the city. Don't go back to your hometown every day; I worry about your safety since your workplace is far away.

Zhou Ning turned around and entered the house, actually bringing along various books. The house in the city had long been prepared; it was the wedding house his grandfather had arranged for him. His parents passed away early, and the old gentleman had made these preparations for him long ago

Why would Su Manli find a repairman as her boyfriend? Isn't her father quite wealthy?

I did not go out to play, I have a case today, and I have been busy all the time. I left my phone in the investigation box, so it probably has no signal.

Are there any other gains

Grandfather, I have always listened to Xu Da and my master, after all, they have experience. However, my master was in a car accident today and his leg was fractured.

According to the models of these two vehicles, retrieve surveillance footage from various angles on the overpass on the south side of the North Outer Ring Road, as entering the North Outer Ring Road from south to north is a necessary route. You should personally take a few people and inform the traffic police team, do not tell me that it needs to be done tomorrow

Seeing this situation, Zhou Ning quickly raised his hand

Zhao Xinli chattered incessantly, and as Xu Dayuan raised his hand, he instantly fell silent, realizing that he had once again succumbed to his old habit

Dr. Zhou, the forensic expert, indeed has a different level of education. The experiments you mentioned are beyond my understanding, but I grasp the essence. You mean to say that these brake marks are like fingerprints, each one being unique, correct

Well, the case has not been solved yet, I cannot say this is a matter of discipline

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

Zhao Xinli shrank his neck, bared his teeth, and quickly held the picture up in front of Xu Dayuan, while keeping a safe distance away.

You are a newcomer, so listen and observe more. Do not think that just because you have read for two days, you no longer know your own surname

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

Zhou Ning was taken aback, and Xu Dayuan waved his hand

Without further ado, Zhou Ning has left, and it was Xu Dayuan who arranged for a police officer to drive him back.

Zhou Ning nodded

Upon hearing this, the old man loosened his grip on the broom. Zhou Ning quickly placed the broom head on the low wall, a height that the old man could not reach.

Using pyrolysis gas chromatography-mass spectrometry for analysis and comparison, I plan to ask my advisor later to see if anyone has conducted such an analysis. This would provide an additional layer of evidence in identifying the perpetrator

Xu Da, I am not in a hurry. By the way, how is the investigation into social relations going?

Case 1

I will move over tonight. This case is somewhat tricky, and my master is injured. I must be on call at all times. Don't worry, I will return as soon as I finish the case.

Zhou Ning tightly gripped the evidence bag. Previously, he thought this item could be sent for inspection, but according to the time annotations in that forensic field manual, such items did not exist at this time. Moreover, he had never heard of the several experiments mentioned on it, and their principles were also inexplicable.

The eleven large characters "Analysis of Cases in Secondary Forensic Scene Studies" above are extremely conspicuous; their size and thickness instill a sense of dread. No matter how much he wishes to retreat and struggle, he cannot move and can only sit down, flipping through the pages one by one.

Xu Dayuan raised an eyebrow, his face filled with curiosity, as he reached out to grab the evidence bag. Zhou Ning struggled a couple of times before reluctantly letting go.
