Rebirth 2014: I, the King of Criminal Investigation

Chapter 179 Another Brain Game

What happened in the year ahead?
Yu Dazhang stared at the housekeeper in front of him and felt that this case was a bit strange.

It wasn't him who harmed Liu Zhengyang, so why would he run away?
He also sent a video to Liu Siyuan, admitting that he did it.

Take the blame for someone else?

wrong.

This case will remain unsolved even after another year. The criminal has not revealed any clues, so there is no need for the housekeeper to go to such trouble.

Taking the money and running away is at most theft, but if you admit to murder, it is a felony.

Seeing Yu Dazhang standing there in a daze, the butler couldn't help but ask:

"Officer, what's the matter? Is there anything wrong?"

"Oh, no." Yu Dazhang came back to his senses, looked at him and said:
"Thank you for your cooperation. We will come again if there is any progress in the case."

He did not use vague words like "if" or "suppose", but said this in an affirmative tone.

As a result, after hearing this, the butler not only did not have any special reaction, but responded very seriously:
"If you need any cooperation, you can contact me at any time. If the gentleman was really murdered, I also hope to catch the murderer."

Seeing his sincere and serious expression, Yu Dazhang felt even more headache.

Solving a case is a process of finding clues and verifying facts. But now the clues are gone just as we start.

In addition, it has been more than a year since the case occurred, and many details at that time can no longer be traced.

Yu Dazhang and the other two then left the Liu family villa.

Compared to when they came here with their heads held high, they are now a little dejected.

Out of trust in Da Zhang, Ma Jian and Liu Miao thought they could find new clues here, but to their surprise, they got nothing.

After returning to the detachment, Yu Dazhang stood by the window in the corridor, looking at the street outside with unfocused eyes.

It is indeed a difficult case and it is not simple.

He had noticed it when he was looking at the case file before.

Although Liu Zhengyang's autopsy report showed that he died of natural causes, the police officers who handled the investigation did not take the case lightly. Instead, they conducted a very careful and detailed investigation.

They checked all the people involved and even made some notes in the transcripts.

This shows that they have carefully analyzed the contents of each transcript.

Which ones are unreasonable and which ones can attract attention.

Places like this are specially marked.

It was precisely because the previous records were very detailed that Yu Dazhang did not ask too many questions to Liu Siyuan and the housekeeper when he was at the Liu family.

One hypothesis after another emerged in his mind, and he rejected them one by one.

Later, Yu Dazhang sneered with disdain.

Someone is planning this.
"Another one playing with his brain." He muttered unconsciously.

If he hadn't known in advance that the butler would run away, he would probably have been deceived by what he saw.

It was a natural death, there was no main suspect, no problems were found in everyone's statements, and there was not even a motive for the crime.

It seems that this case is just a farce.

A farce instigated by Liu Zhengyang's daughter Liu Qi.

If she hadn't reported the case, there would have been no such case.

After the police investigation was completed, she also firmly refused to close the case.

Did Liu Zhengyang really tell her that he would be murdered half a month before his death?

He had also read Liu Qi's statement many times, and the police officers who had previously handled the case had asked her similar questions.

She answered with certainty.

She also asked Liu Zhengyang who wanted to harm him, but she did not get any answer from Liu Zhengyang.

It seems that even Liu Zhengyang himself doesn't know.

This is a bit bullshit...Yu Dazhang thinks this is an obvious logical loophole.

Unfortunately, there is no evidence. Liu Zhengyang has turned to ashes and there is no way to verify what he said.

Is there a perfect crime in the world?

No.

Because perfect crimes go undetected.

Since this case has come to light, there must be some flaws.

It’s so enjoyable, so enjoyable…Yu Dazhang’s smile became colder and colder.

When I was in the police academy, a teacher once said: When a case stumps everyone, it means the suspect is smart and cunning enough. To put it bluntly, you can't beat him and you are crushed in terms of IQ.

In this case, finding clues and verifying information are no longer important at this stage.

The other party took all these into consideration and set up a dead end for the police.

"Then it's just a matter of playing with IQ."

Yu Dazhang became more and more excited.

When your attitude towards something changes, your mentality will naturally change as well.

Using existing investigative methods to solve the case will certainly be a headache.

But if you look at this case as a game, it would be different.

"Throw away those rules and do it my own way."

Yu Dazhang narrowed his eyes slightly, revealing a cunning light, and whispered to himself:

"If I were the murderer."

"If you want to kill Liu Zhengyang in his villa, what methods can you think of..."

"One, sneak in and poison Liu Zhengyang's food and water."

"Second, take advantage of the characteristics of Liu Zhengyang's heart disease and tamper with his medicine."

"three……"

"No, the first two methods won't work!"

Yu Dazhang’s eyes suddenly widened.

Liu Zhengyang died of a sudden heart attack, not poisoning, and there are surveillance cameras inside and outside the villa.

The police officers who conducted the initial investigation checked the surveillance footage and did not find any suspicious persons.

It was even more impossible to tamper with his medicine.

Since it was not done by an outsider, the only people who could have access to Liu Zhengyang's drugs were people around him.

But after investigation, the children, housekeeper, and servants were all ruled out as suspects.

And there is nothing wrong with Liu Zhengyang's autopsy report.

If Liu Zhengyang died from taking other drugs, it would definitely be identified by the forensic doctor.

When it comes to drug testing, forensic scientists are even more experienced than professional doctors.

"There is no surveillance in the study. Is it possible that..."

When Yu Dazhang thought of Liu Zhengyang's illness, he suddenly noticed a detail.

videoconference!

He actually fell ill while he was having a video conference at home.

Is it a coincidence?

No.

Since this is a setup, this timing must have been deliberately designed by the other party.

The idea is to allow executives participating in the video conference to become witnesses.

The other party even took this into account.

Be as meticulous as a hair!

Yu Dazhang made a silent evaluation in his heart.

However, this also gave him a direction for investigation.

Since there is no inference or investigation in this regard in the case file, it proves that the police officers who handled the case before did not think of this aspect.

Thinking of this, he took out his cell phone and looked for the housekeeper's phone number.

Before leaving the Liu family, Yu Dazhang specifically asked the housekeeper for the contact information.

After dialing, he asked directly:

"How long does it usually take Liu Zhengyang to hold a video conference at home?"

"Well..." The butler on the other end of the phone hesitated for a moment, then replied:

"The shortest meeting lasts more than half an hour. Sometimes, the meeting has a lot of content and lasts more than two hours."

On average it’s more than an hour... Yu Dazhang silently calculated in his mind.

"By the way." The butler added:
"The gentleman passed away shortly after the video conference began. I remember it was only about ten minutes into the conference."
