Chapter 23 Your eyes are so good
The car stopped in front of a residential building.
"This is it." Qian Cheng pointed to a window on the third floor:
"After the homeowner reported the crime, our technical department came to the scene immediately, and I was responsible for taking photos and retaining the traces extracted."
Qian Cheng regretted telling the other party that he majored in technology.
Along the way, he has been asked various questions by Yu Dazhang, asking him about his judgment of the crime scene and investigation results from various angles.
Now he could be sure that the fat man was really looking for clues.
"Do you have the on-site investigation report?" Yu Dazhang asked.
"Yes, it's in the car."
As he spoke, Qian Cheng got down from the driver's seat, opened the rear door, and took out a folder from a cardboard box on the rear seat.
Yu Dazhang also got out of the car. After watching Qian Cheng take out the report, he waved to him:
"Come on, follow me upstairs."
Follow you upstairs? Qian Cheng almost threw the report on the ground.
Does this fat man think of himself as a leader?
It's true that I offered to accompany you, but you are the new guy, okay?
Even if I go to see the crime scene, you have to follow me.
Yu Dazhang took a few steps and saw that Qian Cheng hadn't followed, so he urged:
"Let's go, stop dawdling."
You still think I'm wasting my time... Qian Cheng's veins are popping on his forehead and he wants to throw a report.
But I can't explain why, but my legs followed me obediently, as if they had their own consciousness.
My brain says no, but my body is honest.
He wanted to see what other useful clues the fat man could find.
If you can’t find it...
Hum~
Wait to be insulted!
Arriving upstairs, Yu Dazhang followed Qian Cheng's guidance to a separated room.
This is a characteristic of rental housing in Songhai. A house is divided into several single rooms and rented out to different tenants.
Compared with renting out the whole property, the landlord can earn more rent by doing this, and some tenants with financial constraints can also rent cheaper houses.
Kill two birds with one stone.
After all, this is a first-tier city where land is at a premium. Low-income migrant workers who want to live in a house can only rent small cubicles like this.
Yu Dazhang first glanced at the empty room of more than ten square meters, and then set his eyes on the single bed against the wall.
"After the body was removed, the bed was not touched, right?"
Surveying the site is the job of the technical department, and Yu Dazhang doesn't know much about it. Everyone has their own responsibilities and professional scope.
"Of course." Qian Cheng explained confidently:
"The principle of site protection is: maintain the original state and prevent changes."
"The most basic requirement is that there can be no more and no less."
"Any facility on site may leave traces related to the crime."
When it comes to on-site investigation, Qian Cheng seems to be a different person. The previous casualness disappears in an instant and is replaced by concentration and seriousness.
"That's OK."
Yu Dazhang didn't take it seriously. After all, he was professional in this area.
When he came to the bed, he lowered his body so that his head formed a ninety-degree angle with the bed, and then started from the head of the bed and moved little by little to the end of the bed.
At the same time, observe every detail on the bed with both eyes.
Qian Cheng stared at Yu Dazhang's every move and felt that this fat man was simply unnecessary.
I have the survey report in my hand, just look at it.
Your current actions make it clear that you don’t believe in the professionalism of our technical department!
After watching for a long time, Qian Cheng couldn't bear it anymore.
"What are you looking for?"
"Don't talk yet."
Yu Dazhang raised his hand to signal him not to disturb him by making any noise.
After a while, Yu Dazhang moved to the end of the bed and stayed there for two minutes. It was as if there was something at the end of the bed that attracted him and made it difficult for him to leave.
But in Qian Cheng's eyes, there was obviously nothing at the end of the bed.
"Extract the footprints and show me." Yu Dazhang stood up and turned to look at Qian Cheng.
"Oh, okay."
Qian Cheng quickly turned the report in his hand to the designated page, then pointed at the picture above and said:
"After investigation and extraction, it was determined that the footprints at the scene were all left by one person. Based on these footprints, the person was an adult male and should be the suspect Kong Lingjie."
Yu Dazhang nodded after hearing this, and then asked for confirmation:
"Are you sure there are only his footprints?"
Qian Cheng was stunned by the question. He didn't understand what Yu Dazhang meant by asking, but he still replied:
"There were another person's footprints at the door. After comparison, it was confirmed that they belonged to the landlord."
Determine what the use of this is... Qian Cheng became more and more confused when asked.
I originally thought that the fat man in front of me was pretending to be diligent, but the serious look on his face didn't seem like he was pretending.
Check out the 16-9 book bar and see the correct version!
"Okay, now it's your job."
Yu Dazhang gestured to Qian Cheng to come to the single bed, and then pointed to the center left of the end of the bed:
"Look at that little black dot. Extract it and take it for inspection."
"Where?"
Qian Cheng looked in the direction of Yu Dazhang's finger and couldn't see the little black dot even after changing several angles.
"That's right!"
Yu Dazhang was also a little anxious.
It's true that anyone can do criminal investigation these days, but he's still investigating the scene with this look in his eyes.
What a delay.
"No!"
Qian Cheng put his head almost to the end of the bed and didn't see it.
"Look at my finger, it's at the tip of my finger." Yu Dazhang stretched out a finger and gently pressed it on the bed sheet.
"I see it, I see it, ah ah ah ah, it's really a little black dot. Your eyes are so good, you can spot it."
Qian Cheng shouted excitedly.
Still keeping his head pressed against the sheets, it was like a child seeing a favorite toy.
"It's hard for me to look at it from such a close distance. It almost blends in with the pattern of the bed sheets. How did you discover it?"
This is probably the legendary technical geek... Yu Dazhang found that Qian Cheng was particularly excited whenever he encountered professional matters.
At the same time, he also discovered that his eyesight was not just as simple as seeing farther than ordinary people.
He is also much better than ordinary people at observing the details of objects.
"This is not important, just hurry up and work."
Yu Dazhang directly ignored Qian Cheng's question. This fact is difficult to explain.
"Wait for me a moment."
After Qian Cheng finished speaking, he quickly ran downstairs and soon brought up an inspection box and a camera.
After taking out the tool to complete the extraction, he put the extract in the glass container back to its previous position.
After taking pictures and keeping them, he stood up and nodded to Yu Dazhang:
"Okay, we will get the test results at noon tomorrow at the latest."
Seeing Yu Dazhang's thoughtful look, Qian Cheng continued to ask:
"You came here just to find traces that our technical department missed?"
Qian Cheng did not think this was an oversight by the technical department.
Such a small black spot has reached the point where it is difficult to detect with the naked eye. Even if you look for it with a magnifying glass, you may not be able to find it.
This has nothing to do with professionalism, it's purely a matter of who has the better eyesight.
"No." Yu Dazhang shook his head and denied:
"Our starting points are different. You are looking for traces that already exist, but what I am looking for..."
"It's a trace that should have appeared but didn't."
