Rebirth 2014: I, the King of Criminal Investigation

Chapter 30 You Finally Look Like a Human

"I just said that, but you took it seriously." Yu Dazhang smiled:
"If we can solve the case just by guessing, then what is the point of having a technical department?"

Upon hearing this, Qian Cheng's expression returned to normal.

This is reasonable. The final conclusion of the composition of an object still depends on the test results.

"I'll go now and give you the test report as soon as it comes out."

After Qian Cheng finished speaking, he quickly left the meeting room.

At this moment, Yu Dazhang was the only one left in the huge conference room.

He had noticed when assigning the tasks just now that no one in the task force, including his master, understood his approach.

Let Lu Zhongxin be tried towards 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 things, but there were some words he couldn't say.

Kong Lingjie’s alibi in his previous life must be true, and this is also the most crucial evidence for him to escape punishment.

And that famous lawyer must have been hired by someone else to pay for Kong Lingjie.

From these two points, it can be inferred that Kong Lingjie is just a puppet pushed to the front.

However, Yu Dazhang was unable to speak out what had not yet happened.

His current situation is: he knows it in his heart but cannot say it out loud.

Even if he says he is reborn, someone has to believe him.
.
Near noon, Qian Cheng came back with a test report in his hand.

"The report is out. What do you think that particle is?"

Qian Cheng looked very excited. As long as it was related to his profession, he would become extremely excited.

"Carbon." Yu Dazhang answered without even thinking:
"Activated carbon, to be exact."

Qian Cheng: !!!!!!

It leaked, it leaked!

You said before that you couldn't solve the case by guessing alone, but it turns out that your guess was so accurate.

Can this thing be distinguished with the naked eye?
Is your eye connected to a measuring device?

What on earth have you become!

Seeing Qian Cheng staring at him blankly with his mouth open, Yu Dazhang said with a smile:

"Nothing to be surprised about."

"The investigative report showed that the body was placed on its back on the bed, with the head at the foot 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 deceased's hair."

"This is also the only hypothesis that can establish a connection with the deceased."

"Combined with the current situation in the rental house, it is easy to infer the function of the particle."

What is the function... Qian Cheng looked as if he had seen a ghost.

Big brother, please continue!

If I could guess it, I wouldn’t have gone to the technical department.

Seeing Qian Cheng seemed to be hesitant to speak, Yu Dazhang was also a little confused.

I've pointed it out so obviously, yet you still don't know?

In desperation, he could only continue:

"When we two went to the scene that day, didn't you notice anything wrong in the house?"

Qian Cheng thought about it, and finally shook his head helplessly:
"Nothing special. When we went there, the scene had already been investigated."

He was already very surprised that Yu Dazhang could find two new clues. He really couldn't think of what else might be wrong.

"The smell!" Yu Dazhang showed a look of disappointment:
"Under normal temperature, a body will begin to emit an odor 24 hours after death, and after 48 hours it will become so smelly that it is difficult to get close to."

"But when Zhang Yan's body was found, she had been dead for four days. Given the temperature in Songhai right now, it must have smelled really bad."

"Even if the body is removed, the smell will not go away for at least a week." "But when we were in the rental house, there was also a peculiar smell, but it was very light and could not be detected without careful smelling."

“You said when you were at the scene that the principle of site protection is to keep it in its original state.”

"Then there will definitely be no one to deodorize the scene."

"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, I know. The murderer took advantage of the strong adsorption capacity of activated carbon to deodorize and preserve the corpse."

I did think of it, but that was on the premise that the answer would be revealed soon in the big chapter.

Qian Cheng looked at the newcomer in front of him who had not yet been hired and began to doubt his own IQ.

How come we were able to find so many unusual things when we went to the scene together?

And I really just went on a one-day tour on site.

At this moment, he felt that his thoughts were opened up and his mind became active.

"The murderer must have read books on forensics, and it is even possible that he specialized in this field."

Qian Cheng said while thinking:
"Freezing a body will definitely be discovered during the autopsy. This is a method that only laymen would use."

"Only people who have studied forensic science would think of using activated carbon for treatment."

"This not only masks the smell, but also effectively slows down the decomposition of the body."

"That is to say, the deceased's actual time of death must be pushed back further!"

You finally look like a human being...Yu Dazhang nodded with satisfaction.

He had previously suspected that Qian Cheng was just there to fill in the gaps, after all, it was rare for people from the technical department to join the task force.

But after spending some time together, Yu Dazhang discovered that Qian Cheng's professional knowledge had reached the level of mastery.

There is no need for such a person to analyze the case, as long as he can give professional opinions quickly when doubts are raised.

Just like now.

Yu Dazhang could imagine that the murderer used activated carbon to preserve the corpse, but he didn't know that activated carbon could also slow down the decay of the corpse.

This is the gap between us and professionals.

"And more." Qian Cheng spoke more fluently and began to correct Yu Dazhang's mistakes:

"The forty-eight hours you just mentioned is particularly stinky and not rigorous."

"The body actually starts to soften after 42 hours, and the urine and feces in the body are excreted due to muscle relaxation..."

"Alright, alright." Yu Dazhang interrupted hurriedly:
"You don't need to explain it to me. I just need to know the general idea."

It’s almost lunch time, I think you are deliberately trying to spoil my appetite...Yu Dazhang understands these tech geeks.

As long as they talk about their profession, they will get excited and want to tell you everything they have learned.

But it’s also 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 moved forward, Kong Lingjie's alibi will no longer be valid.

"Brother Qian, you still have to go to the appraisal center." Yu Dazhang said quickly:
"Explain the new situation to the medical examiner, request another autopsy, and determine the time of death as soon as possible."

Yu Dazhang knew that this was very important because the time of death was also a form of evidence.

And it’s not enough to just talk about it, there must be a real and valid autopsy report.

"I'll go now." Qian Cheng said, handing the particle inspection report in his hand to Yu Dazhang.

The time of death was inaccurate, as he had inferred 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 now full of energy.

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."
