"Uncle Yang, do you know what Yang Bing does?" Bai Mo could tell that Yang Donglai was a man of rules.
Don't look at the complaints on his lips, if he didn't want to cooperate, he would have driven them away long ago.
Still looking dissatisfied, Yang Donglai answered truthfully, "Isn't he just a street gangster?"
Bai Mo smiled and pointed to the furniture in the room, "Do you think a street gangster can afford such a big house?"
The file contains an investigation of Yang Bing's family. His parents are both retired workers with low but stable incomes. Yang Bing does not have a regular job, so it is impossible for his family to afford a large house of 140 square meters.
It is obvious that Yang Bing earned his money through loan sharking.
"I don't know how he earns the money. I just heard from some old colleagues that he was engaged in loan sharking." Yang Donglai's answer was straightforward.
"You don't care what he does?" Bai Mo asked.
"What's the use of caring? When I first got to know him, I talked about him every day. He said that if I stopped him, he would continue to join society." As he spoke, Yang Donglai's eyes turned red and he sighed, "He will not die. Is it just because you are looking for someone to collect a debt?"
The old father's expression was sincere when he mentioned his son's past, and Bai Mo could tell that he really didn't know the details of Yang Bing's loan.
It was no longer necessary to ask further. Bai Mo turned over a page in the small notebook where the questions were recorded and changed into a comfortable position.
"Uncle Yang, do you remember the police who came to see you for the second time?" Bai Mo asked.
Hearing this question, Lu Yang's lips raised a smile. Unexpectedly, Bai Mo also noticed this detail.
Lu Yang looked at Bai Mo, full of curiosity. Nearly half a year had passed. How would Bai Mo ask an older man?
Yang Donglai shook his head, "It's been so long, how could I remember? Why are you asking them?"
"They are not the police, they may be some reporters who want to expose Yang Bing's past." Bai Mo has already thought of his words, "Although what Yang Bing did is wrong, you don't want him to be written off as a person who deserves death, right? We The police will not allow anyone to impersonate us."
Bai Mo's lie was perfect. It not only explained the other party's motivation to pretend to be a police officer, but also connected it with Yang Bing's reputation after his death.
Yang Donglai clenched his fists instantly and gritted his teeth and said, "No wonder some people said that Yang Bing deserved to die. It turned out to be this group of people."
"Do you still remember what they asked?" Lu Yang suddenly asked at the side.
Yang Donglai frowned and thought for a while, "It's almost the same as what you asked! He asked some about Yang Bing and asked me if I knew who he was lending money to and who he was lending money to."
He looks very much like Ma Zhenwei. Is he worried that Yang Bing has his evidence?
Just as Lu Yang was thinking about the identity of the other party, Bai Mo asked again: "How much of their appearance can you remember?"
"There were two people. One of them was wearing a mask and didn't speak much. I didn't pay attention." Yang Dong looked at the ceiling and began to remember hard. "The other one is very thin, about the same height as me. He speaks our dialect and has a very pointed chin."
Bai Mo began to draw in a small book, "Compared with Yang Bing, his eyes are bigger or smaller?"
"Small!" With a clear reference, Yang Donglai didn't have to recall the specific details, and the answer he gave was much more certain.
"What about the nose? Compared with Yang Bing, is his nose larger or smaller..."
In this way, guided by Bai Mo's questions, a portrait of a man appeared in the small book.
Unfortunately, too much time passed, and Yang Donglai was unable to determine how similar Bai Mo's portrait was to the fake policeman.
Saying goodbye to Yang Donglai, the three of them returned to Lu Yang's car.
Lu Yang took Bai Mo's black pen portrait and said, "Yang Donglai's description is too vague. Is this useful?"
Lu Yang, who works in Kyoto, naturally knows the role of portrait painters. He has also met several powerful portrait painters.
"It can only be used as a reference, but I feel that the similarity should be more than 50%." Bai Mo just did it casually. If Yang Donglai has a strong memory of human faces, he will definitely be able to draw that person.
Ma Zhenwei disappeared, Yang Donglai didn't know the details of Yang Bing's loan, and the line was broken.
Next, Lu Yang could only focus on the police officers who originally investigated Liu Changyu's murder case, namely Captain Lin Feng of the Second Team and Police Officer Li Qiang.
It was already five o'clock in the afternoon when the three of them returned to the criminal police team. Lu Yang asked them about the details of the original case.
After the case occurred, Lin Feng was responsible for tracing the whereabouts of Liu Changyu, and Li Qiang was responsible for visiting nearby households to find witnesses.
Under Lu Yang's constant questioning, he finally found a piece of evidence that had been ignored at first.
When Li Qiang visited witnesses, he found that there were very few residents in the shanty town, and no one noticed anything unusual on the day of the crime.
The shantytowns were built in rows. Li Qiang found a car's driving recorder outside the entrance of one of the rows. It captured an extremely blurry picture of someone walking into the shantytowns.
Li Qiang did not pursue this clue at the time.
First, because there was dew on the car window, the picture on the driving recorder was extremely blurry, and it was impossible to see the other person's face clearly.
Secondly, it was because the road the visitor entered was not Liu Changyu's residence, but an adjacent road.
The third reason is that Lin Feng caught Liu Changyu quickly and Liu Changyu confessed to the crime, so Li Qiang felt that there was no need to pursue it.
Fortunately, Li Qiang saved the original evidence and found it from the computer and gave it to Lu Yang.
It was already half past six after the questioning, and only Lu Wan was left sitting in the back room of the criminal police office.
"What a pity!" After opening the video, Lu Yang understood what it meant to be extremely blurry. Affected by the moisture on the car window, he could barely see a blurry figure entering the shanty town.
"If we can find this person, maybe there will be new discoveries." Meng Xiu also looked regretful, "In case the murderer is someone else, we just need to know if he has met anyone else."
Bai Mo stared at the screen for a long time, frowning from time to time, "I should be able to draw him."
Lu Yang and Meng Xiu looked back at Bai Mo with expressions of disbelief on their faces.
"But it may take a long time." Bai Mo said no more nonsense, went next door to get a drawing board and sat in front of the computer.
Bai Mo's idea is very simple. The blurred image is due to the refraction of water vapor. The source of light is fixed, and the people in the picture are moving. As the distance changes, the refraction changes slightly.
As long as he calculates the value of water vapor refraction of the picture through each frame, he can deduce the picture before refraction.
The reason sounds very simple, and it sounds like a physics problem, but the changes are impossible to calculate through data. What is required is a painter's most sensitive capture of light.
