Coroner Coroner

The pair of legs were tightly tucked under the chair, and the two hands seemed to have no place to rest, sometimes clutching the armrests, sometimes putting them on the legs.

Lin Xinyi didn't need to learn any micro-expressions, and Lin Xinyi knew that this guy was panicking.

"Mr. Nishimoto, are you still refusing to plead guilty?"

"We must know that the interrogation of Heiyan and Kawashima is also going on at the same time, we don't know the situation on their side."

"If you plead guilty one step behind them, I'm afraid you will suffer a big loss!"

"Why, do you have such confidence in them that they won't betray you?"

Another interrogator who partnered with Lin Xinyi was in charge of singing the black face, speaking in such a cold tone.

And Lin Xinyi played the role of a good policeman, playing the emotional card with Nishimoto Ken:

"Mr. Nishimoto, stop being stubborn."

"I've asked, you were a very good friend with Keiji Aso back then."

"You killed your friends for the sake of profit, even if you are yourself, you probably can't bear such a crime, right?"

"Otherwise, you wouldn't have lived in such a muddle these two years."

"So, don't go on like this..."

"You can't get out of the shadows brought about by those crimes at all. Living like a walking dead, how much better is it than being in prison?"

Lin Xinyi persuaded Nishimoto Ken to bow his head and surrender from another angle with emotion and reason.

"I..." Nishimoto Ken muttered at the corner of his mouth, obviously touched.

But he still didn't want to admit to the crime of murder, and still insisted on not letting go.

Of course he was also hesitating in his heart... Is his persistence really meaningful?

Could it be that the other two guys have teamed up to sell him and let him take the blame for the chief culprit?

Time passed slowly amid the cold reprimands and patient persuasion of the two interrogators, as well as Nishimoto Ken's repeated entanglements, suspicions and panics.

Soon, almost 10 minutes passed.

Bang bang bang.

As agreed in advance, there was a light knock on the door of the interrogation room.

"Please come in."

The door was pushed open, and it was the actor Lin Xinyi had arranged in advance, Mao Lilan, who came in.

Now every time she and Lin Xinyi came out to handle a case, she would consciously change that immature high school uniform into a mature and formal suit and skirt.

Putting on this "social man" dark suit and skirt, coupled with the lean temperament cultivated by practicing karate all the year round, even though the facial features are still a little green and immature, the overall look looks like a mature and capable female police officer.

"Manager Lin."

As soon as Mao Lilan came in, she greeted Lin Xinyi formally.

Lin Xin was very satisfied with her appearance, temperament, and acting skills, so she took on the scene with a natural expression:

"Maori inspection, what's the matter?"

"Yes." Mao Lilan nodded.

However, the lines she read were completely different from Lin Xinyi's arrangement:

"News came from the other two interrogation rooms that Kawashima and Heiyan have pleaded guilty."

"They have always been at odds with each other, the conflict is extremely deep, and they have been fighting among themselves for many years."

"After entering the interrogation room, they couldn't trust each other. They were worried that the other party would betray them and plead guilty before themselves."

"So, not long after entering the interrogation room, both Chuan Dao and Hei Yan bowed their heads and pleaded guilty."

"Eh..." Lin Xinyi was stunned when he heard this:

He just taught Mao Lilan a word, why are there so many popping up now?

Impromptu?The details are quite similar.

But it doesn't work...

Interrogating and inducing a confession is like licking a dog. Only when the words are ambiguous and ambiguous can people's mood fluctuate.

You spoke in such detail, and also clearly stated that Kawashima and Heiyan had taken the opportunity to plead guilty first, how can you make people plead guilty obediently?

"Ugh…"

Seeing that Mao Lilan not only did not perform as planned, but let himself go and ran away with the plot, Lin Xinyi felt very uncomfortable.

He had no choice but to bite the bullet and continue:

"Okay, that's great!"

"Mr. Nishimoto, both of your accomplices have pleaded guilty, what are you insisting on?"

"Let's tell the truth quickly..."

"Are you kidding me!" Nishimoto Ken roared with an ugly face.

"I didn't kill anyone, the case of Keiji Aso has nothing to do with me!"

Takeshi Nishimoto, who had been frightened all the time, finally broke out all his long-suppressed resistance.

Just like what Lin Xinyi was worried about: because he heard that his two companions had betrayed him, and that he had already ranked last in the "competition", he was so emotional that he would not let go.

"Miss Maury..."

Lin Xin pulled Mao Lilan aside, and said softly with some helplessness:

"You made it too inappropriate."

But Mao Lilan replied innocently:

"But, what I just said is true."

"With the confessions of Heiyan and Kawashima, it is useless for Nishimoto not to plead guilty."

"Eh?" Lin Xinyi was a little surprised: "The two of them really pleaded guilty first?"

"yes…"

Mao Lilan said with some emotion:

"They are fighting so hard that they are afraid that they will be preempted by the other party even if they plead guilty."

"When I went to see them, they had already signed the confession and were sent out of the interrogation room, and they were scolding each other in the aisle..."

"Whoever is scolding will surrender faster."

Chapter 129 Keiji Aso's suicide note

Lin Xinyi was shocked by this news:

Although he knows that the theory of the prisoner's dilemma is really useful, and in actual detection, this kind of interrogation method that separates interrogation, breaks trust, and stimulates competition is basically tried and tested.

However, according to Lin Xinyi's experience in the police force for several years:

The theory is easy to use, but it does not mean that the practice process is easy.

Because such criminals who dared to join hands in committing major murders generally have a strong resistance mentality, their interrogation often takes hours or even days.

It's like downloading hundreds of gigabytes of resources with an online disk account that has not been a member. The interrogators have to use extraordinary patience, meticulous and time-consuming work to break down the criminal suspect's psychological defense bit by bit.

And now, Heiyan and Kawashima, the two suspects pleaded guilty in less than 20 minutes.

Not even resisting...

Even if you are determined to surrender, if you persist for a while, you can force the other party to come up with a better agreement, right?

Therefore, Lin Xinyi never expected that Heiyan and Chuan Dao would plead guilty so quickly.

"This is too cooperative!"

He sighed deeply in his heart.

But this is Lin Xinyi's empiricist error, and there is no specific analysis of specific issues:

The basis for resisting the prisoner's dilemma is the mutual trust among multiple suspects in a criminal gang.

As for Hei Yan and Chuan Dao, they have long turned against each other because of their election for the village head. Over the years, their grievances have been deep, and they have no trust in each other.

In addition, a more important reason is:

While distrusting each other, Heiyan and Kawashima are also extremely distrustful of Nishimoto Ken:

Ken Nishimoto quit the business 2 years ago due to psychological problems. In the past 2 years, he has been nesting at home every day, from a shackles to an abandoned house.

Every time he met them, Nishimoto Ken would not turn on any pot, and insisted on yelling crazy things like "Keiji Aso is still alive" and "Keiji Aso is here for revenge".

Before the police came, Nishimoto Ken frightened himself crazy.

Now that the Dong Chuang incident is revealed and the police are here, how can this coward still control his mouth?

Anyway, Ken Nishimoto will definitely not be able to persist in pleading guilty and confess them——

That being the case, they might as well admit it earlier, grab a chance to be the first to plead guilty, surrender and get a reduced sentence.

Kuroiwa Tatsuji and Kawashima Hideo both thought so.

What they didn't expect was that the shortcoming of the team they were most worried about turned out to be the stone in the latrine that persisted until the end:

"No, I didn't kill anyone."

"Don't believe the nonsense of Heiyan and Kawashima... I was only involved in the business, not the murder!"

"At that time, it was Heiyan who threatened me to help make false testimony, that's all... other things have nothing to do with me!"

Nishimoto Ken's face was covered with beads of sweat, but his mouth was even stiffer than before.

"When death is imminent, you still dare to talk about it?!"

"Heiyan and Chuandao have been guarded by people since they were arrested, and there is no chance to collude a confession in advance."

"If they all accuse you of being involved in the murder while being interrogated separately, and the details of what they said can match each other."
