Chapter 30 You finally look like a human being
"That's what I said, and you took it seriously." Yu Dazhang smiled:
"If you can solve the case just by guessing, why do you need a technical department?"
When Qian Cheng heard this, his expression returned to normal.
This is only reasonable. In the end, determining the composition of an object depends on the test results.
"I'll go now. I'll bring it to you as soon as the inspection report comes out."
After Qian Cheng finished speaking, he quickly left the conference room.
At this moment, only Yu Dazhang was left in the huge conference room.
He had seen it when he assigned the task just now. Everyone in the task force, including Master, did not understand his approach.
Let Lu Zhongxin try in the direction of innocence, and let others investigate the social background of both parties in the case.
These two points alone show that Yu Dazhang has determined that Kong Lingjie is not the real murderer.
No one knows where his confidence comes from.
Yu Dazhang was also helpless. He also wanted to explain the matter, but there were some words he couldn't say.
The alibi of Kong Lingjie in his previous life is definitely true, and it is also the most critical evidence that he can be exonerated.
And that barrister, someone else must have paid for Kong Lingjie.
It can be inferred from these two points that Kong Lingjie is just a puppet who was pushed to the stage.
Unfortunately, Yu Dazhang couldn't tell what happened yet.
His current situation is: he knows it in his heart but cannot say it out loud.
Even if he says that he is a reborn person, someone has to believe him.
.
Near noon, Qian Cheng came back with an inspection report in his hand.
"The report is out, what do you think the particle is?"
Qian Cheng looked very excited. As long as it was related to his major, he would become extremely excited.
"Carbon." Yu Dazhang replied directly without thinking:
"Activated carbon, to be precise."
Qian Cheng:! ! ! !
It's leaked, it's leaked!
You said before that you couldn't solve the case just by guessing, but you guessed so accurately.
Can this thing be distinguished with the naked eye?
Is your eye connected to a measuring device?
What the hell did you become?
Seeing Qian Cheng opening his mouth and not speaking, and staring at him blankly, Yu Dazhang smiled and said:
"Nothing to fuss about."
"The investigation report shows that the body was placed on the bed on its back, with the head at the end of the bed."
"And the particle was found at the end of the bed. The only logical explanation is that... the particle fell from the hair of the deceased."
"This is also the only hypothesis that can connect with the deceased."
"Based on the current situation in the rental house, it is easy to deduce the role of that particle."
What's the use... Qian Cheng looked like he'd seen a ghost.
Brother, keep talking!
If I could guess it, I wouldn't go to the technical department.
Seeing that Qian Cheng was hesitant to speak, Yu Dazhang was also a little confused.
You’ve made it so obvious, yet you don’t know?
In desperation, he could only continue:
"That day when the two of us went to the scene, you didn't find anything wrong in the house?"
Qian Cheng thought for a while and finally shook his head helplessly:
"It's nothing special. When we went there, the site had already been inspected."
Yu Dazhang was surprised that he could find two new clues. He really couldn't think of anything else wrong.
"It smells so good!" Yu Dazhang showed an expression of hatred for steel:
"Under normal temperatures, twenty-four hours after a person's death, the corpse will emit a smell, and if it exceeds forty-eight hours, it will be so smelly that it is difficult to get close to it."
"But when Zhang Yan's body was found, she had been dead for four days. With the current temperature in Songhai, how stinky it must be."
"Even if the body is removed, the smell left behind will not dissipate for at least a week." "But when we were in the rental house, there was also a peculiar smell, but it was very light. You wouldn't notice it if you didn't smell it carefully."
"You said when you were at the scene that the principle of on-site protection is to maintain the original state."
"Then there will definitely be no one to deodorize the site."
"So, the murderer must have used some method to preserve the body..."
When Yu Dazhang said this, Qian Cheng's eyes lit up and he immediately raised his hand to interrupt:
"I, I, I know, the murderer took advantage of the strong adsorption power of activated carbon to deodorize and preserve the body."
I thought of it, but it was also based on the premise that the answer was about to be revealed in the big chapter.
Qian Cheng looked at the newcomer in front of him who had not yet become a regular employee, and he began to doubt his own IQ.
How come we can discover so many unusual places when we go to the scene together.
And I really am on a one-day trip to the site.
Check out the 16-9 book bar and see the correct version!
At this moment, he felt that his thoughts were opened and his mind became alive.
"The murderer must have read books on forensic medicine, and may even have studied this specifically."
Qian Cheng said while thinking:
"If you preserve the corpse by freezing it, it will definitely be discovered during the autopsy. This is a method only used by laymen."
"Only people who have studied forensic medicine would think of using activated carbon for treatment."
"This not only masks the smell, but also effectively slows down the decomposition of the body."
"In other words, the real time of death of the deceased has to be pushed forward!"
You finally look like a human being... Yu Dazhang nodded with satisfaction.
He had previously suspected that Qian Cheng was here to make up his name. After all, it was rare for people from the technical department to join the task force.
But after getting along with him several times, Yu Dazhang discovered that Qian Cheng's professional knowledge could be said to have reached the level of proficiency.
Such a person does not need him to analyze the case, as long as he can quickly give professional opinions when doubts are raised.
Just like now.
Yu Dazhang could imagine that the murderer used activated carbon to preserve the body, but he did not know that activated carbon could also slow down the decomposition of the body.
This is the difference with professionals.
"There's more." Qian Cheng became more and more fluent as he spoke, and began to correct the mistakes that started in Dazhang:
"What you just said is that forty-eight hours is particularly stinky. It's not rigorous."
"The corpse actually begins to soften within forty-two hours, and the urine and feces in the body are expelled from the body due to muscle relaxation..."
"Okay, okay." Yu Dazhang quickly interrupted:
"You don't need to give me some popular science. I just know the general meaning."
It's lunch time soon. I think you are deliberately trying to offend me... Yu Dazhang understands these technical nerds.
As long as they talk about majors, they will get excited and want to tell everything they have learned.
But thanks to Qian Cheng.
Without his professional knowledge, Yu Dazhang would not have known that the time of death could be changed.
If the time of death is pushed forward, Kong Lingjie's alibi will be invalid.
"Brother Qian, you still have to go to the appraisal center." Yu Dazhang said quickly:
"Explain the new situation to the medical examiner, apply for another autopsy, and determine the time of death as soon as possible."
Yu Dazhang knew this was important, because the time of death was also a type of evidence.
And it’s not enough to just say it, there must be a true and valid autopsy report.
"I'll go now." Qian Cheng said, handing the particle inspection report to Yu Dazhang.
The time of death was uncertain, but he deduced it using his professional knowledge.
This means that he also played a role in promoting the development of the case.
Because of this, Qian Cheng is very motivated now.
Yu Dazhang came to the room next to the interrogation room and picked up the microphone on the table:
"Master, let's take a break. The case has changed."
