Chapter 827: The Faulty Lie Detector (4000)

Although it is just a feeling, criminal intuition is actually very important for criminals.

Although this is a mysterious feeling, it is the feedback they get from accumulated experience.

After watching the video, Karasawa and Inspector Megure and others made the same judgment.

There must be something wrong with this guy, Dai Tian Yuno.

Generally speaking, even if a person is innocent, he or she will feel panic and anxious when faced with suspicion in the interrogation room.

But the other party didn't have this feeling at all, and only felt superior.

It's a bit like a player playing a game. No matter how powerful the monster in the game is, you know that it can't jump out of the screen to hurt you.

So you can play around and manipulate the characters in the game like crazy and become the "Fourth Disaster" without any scruples.

This is expressed in the other person's expression, tone, and even every move.

One detail in particular made Tang Ze even more certain that there was something wrong with the other party.

When Miwako Sato opened the door of the interrogation room, Yoshida Uno reached out to check the time, then smiled calmly.

Then, after Inspector Megure received the news from the delivery man, he told him that he could leave.

That posture seemed as if he already knew the answer in advance.

If he was not the criminal, he should not know the time of Koji Kayou's death.

Even if he did meet the delivery man at 9:10, this should not be his confidence.

But where does this confidence come from?

This may be the key to the case.

But unfortunately, all Tang Ze saw was a video recording, and he had no chance to communicate with the other party.

In the video, after Inspector Megure signaled the other party to leave, Shirota Uno stood up and straightened his suit.

"The estimated time of death was revealed through the autopsy. The power of science is truly great."

Before leaving, Dai Tianyuno looked at everyone and said with a smile: "You people should stop suspecting others without any basis.

We should rely more on the power of science to get to the bottom of things."

Before leaving, Dai Tianyuno looked at the three silent people in the interrogation room with a smug smile on his face, then opened the door and prepared to leave.

"Wait a moment!"

After hearing what Dai Tianyuno said, Gao Mu, who was standing beside him, seemed to be reminded. He suddenly called out to him, "If that's the case, can I delay you for a while?"

"What's wrong? Is there anything else?" Dai Tianyuno stopped and turned around to ask.

"We'd like you to cooperate with a lie detector test." Takagi looked at Daita Uno and said solemnly, "Since you say you're not the murderer, you naturally don't feel guilty, right?"

"Provocation? There's no need to resort to such tactics. If you feel comfortable doing so, I'll cooperate with you."

Dai Tianyuno spread his hands and smiled, "Anyway, I don't have any guilty conscience. After the test, you guys shouldn't harass me anymore, right?"

"Of course." Inspector Megure said in a deep voice.

The video ended here, and Gao Mu soon came over and played another video for him.

This video was taken in another room where a lie detector was placed. It is a new department recently opened by the Metropolitan Police Department.

Soon, a person from the forensic department came into the room, and after a conversation with the other party, asked Dai Tianyuno to put on the polygraph.

Polygraphs these days were still very simple. The instrument was placed on a table, and one side of the sensor was tied to the other person's chest and fingers.

As mentioned earlier, a lie detector detects based on breathing, blood pressure, pulse, and changes in temperature of the skin.

In particular, the skin resistance represented by the red line will change significantly.

This red line is really a red line. The current lie detector does not display fluctuations on an electronic screen, but on a rolling paper with lines drawn on it.

Of course, no matter how simple it is, the function is still the same, and the pointer can still change according to the skin resistance.

After the instrument was put on, the preliminary inspection began in the video, which was the test with playing cards mentioned earlier.

In the video, Shirota Uno cooperated with the supervisory staff and began to deny the allegations one by one.

When the question came to whether the playing card "6" was the card he saw, the other party answered "no", and the red line that had not fluctuated before immediately began to swing up and down sharply, drawing a violently fluctuating red line on the white paper that was constantly moving forward.

This also proves that the polygraph is not malfunctioning and is able to detect the lies told by the other party.

But even so, Dai Tianyuno still remained calm after the test.

Afterwards, the forensic personnel handed the other party a list of questions that needed to be asked later, asking them to check and confirm.

That’s right, before the formal test, the person being tested will be informed in advance of the questions that will be asked of him.

This is the "highest tension questioning method", and the content of the question contains something that only the criminals and their criminal team know.

Letting the examinee know the next questions from the beginning is to help him prepare mentally.

After one piece of false information after another is denied, when it comes time to ask the correct questions, the examinee who has been prepared will unconsciously become nervous.

This is a normal physiological reaction of the human body, and most people cannot calm themselves down completely.

This is also the key to this technique.

In the video, the first question asked by the forensic officer was "Did you know the color of the clothes that Koji Kasuke was wearing on the day of the incident?"
