"They didn't investigate the fire scene carefully, and they didn't conduct a systematic and professional autopsy, so they simply closed the case as 'suicide' based on the testimony of the so-called eyewitnesses."

Speaking of this, Lin Xinyi was angry and helpless:

The police handling the case back then had neither ability nor attitude, let alone professional ethics.

Even this shocking case involving three lives can be handled as if it were a summer homework assigned by the teacher.

The results of it?

There is no physical evidence collected at the scene, no autopsy record, only a few false testimonies...

The entire dossier of the Aso Keiji case looked as blank as the summer exercise book before the last day of school!

"There is no physical evidence left. It is said that the body was cremated into ashes according to the custom afterwards and buried."

"In the past 12 years, the fire site is estimated to have been razed to the ground long ago, and it no longer exists."

"This case is indeed very difficult to investigate."

Lin Xinyi's expression was extremely serious.

There is no physical evidence, no scene, no dead body in this case, to be honest...

It's hard for a clever woman to cook without rice, and forensic medicine has no place to play a role.

And Asai Chengshi also understood Hayashi Shinichi's difficulty:

It is difficult for him to help with this kind of unsolved case that has been delayed for 12 years, and the result may be disappointing.

But Asai was not disappointed.

Because, during the 2 years of entanglement and pain, what he wanted to see deep down in his heart...

In fact, he is such a righteous hero who can stop him from killing people and is willing to help him uphold justice.

Now, this righteous hero is finally here.

Finally, someone extended a helping hand to him who was in the dark, and pulled him back from the bloody and sinful death road.

"It's okay, Mr. Lin..."

"Even if I can't find out the result, I will accept it."

Asai Narumi sighed deeply, with relief on his face.

Of course he didn't let go of his hatred completely, but the enemies had already been caught by the police, and it was too late to say anything now.

Perhaps, this is the blessing his father gave him in heaven... I want him to let go of his hatred and live his life well.

Asai Cheng really worked hard to make himself feel relieved and let himself forget about revenge...

But Lin Xinyi said to him firmly:

"No, we must find out the results!"

"For the sake of the three dead, no matter how difficult it is, I will find a way to get those three bastards to obey me!"

There was determination in his tone.

Narumi Asai couldn't understand why this Mr. Lin would give so firmly, persistently, and selflessly for three strangers who had passed away long ago.

But that's Lim Shin-yi's job as a cop.

Asai Chengshi couldn't help being a little touched, he who just tried hard to turn over the past, couldn't help asking:

"Mr. Lin, do you have a way to make those three guys plead guilty?"

"There is a way."

"At least, we've all identified the suspects, and all that's left is to get them to confess through interrogation."

"And interrogations for this kind of thing ... where there's only one suspect, the interrogation tends to be tough."

"But this time there are three suspects, so it's much easier."

Lin Xinyi talked about his thoughts.

Asai Chengshi's eyes lit up, and he said a killer interrogation move that basically everyone knew:

"Prisoner's Dilemma?"

Chapter 128 The Prisoner's Dilemma

Many people are familiar with the concept of the prisoner's dilemma, so I won't outline it much.

In short, just like everyone knows that if you rush to buy a house, the house price will rise, and if you don’t buy a house together, the house price will fall, but most people still worry that they will lose money if they get on the car late, so they rush to buy a house...

The more people in a group, the easier it is for the Prisoner's Dilemma theory to succeed.

And now, the good news is that there are three suspects in this case.

The mutual trust between the three is difficult to maintain stably. After separate interrogation, the psychological pressure they will bear will be more than ten times that of the two-person model.

"Bring Nishimoto Ken, Kuroiwa Tatsuji, and Kawashima Hideo to three rooms for separate interrogation."

"Tell them that the one who pleads guilty first is considered a major surrender and can get a huge reduction in sentence."

"The second person who pleads guilty is also counted as surrender, and his sentence can be appropriately reduced."

"The last one who pleaded guilty will directly designate him as the main murderer, and the sentence will be aggravated."

Such an operation is actually a violation, but it is not impossible.

If the police and the first two criminals reached an agreement in private, and directly put the hat of the principal criminal on the third person, it would indeed be possible for the last criminal who confessed to share part of the crime for the other two, and bear the biggest pot.

"In short, the sooner you confess, the better, and the later you confess, the worse."

"Besides that, remember to keep the three houses far away, and never let them know about each other's situation!"

Lin Xinyi assigned tasks to the police officers, preparing to strike while the iron is hot, and conduct an on-site interrogation on Moon Shadow Island this year.

Although today is not the investigation class that is in charge of criminal investigation, but the security class that focuses on SAT special police.

However, there are also some people involved in the operation of the Fourth Search Section, which is in charge of group violent crimes, and the Drug Gun Countermeasures Section, which is responsible for anti-corruption work.

They deal with those violent gangs and trafficking groups every day, and they are very good at interrogation work.

It's easy to help solve the interrogation of a murder case.

"Each suspect is assigned two interrogators. Everyone knows how to interrogate."

"By the way, I also participated in Nishimoto Ken's interrogation."

Lin Xinyi also specially arranged a position of interrogator for himself.

Because Asai Chengshi told him:

Among Nishimoto, Heiyan, and Kawashima, Nishimoto Ken has the worst mentality.

Since the mysterious death of Yu Kameyama two years ago, and the legend of the curse of "Moonlight" spread on the island, he has become supernatural and confused.

He didn't even dare to continue the drug business, and stayed at home all day, worrying that the "resurrected Aso Keiji" would come to revenge.

Therefore, Lin Xinyi felt that this Ken Nishimoto would definitely become a breakthrough in this case.

"Also, Miss Maury."

Lin Xinyi turned his head again and greeted his good student.

It is still a holiday, and as a student and assistant, Mao Lilan followed Lin Xinyi to Moon Shadow Island this time.

And because there is really no more reliable assistant in the forensics class, Lin Xinyi is also used to letting Mao Lilan who has been by his side assist him in his work:

"Miss Maori, wait outside for the interrogation."

"After about 10 minutes, if the interrogation has not been concluded, you can put on the posture of a formal policewoman and knock on the door, and say something to me:"

"'Management Officer Lin, Officer XX has something important to communicate with you'."

"Then, in front of that Nishimoto Ken, you asked me to go out with you."

"Yes." Mao Lilan nodded cleverly: "I understand."

Without Lin Xinyi's explanation, she can understand the purpose of this arrangement:

"Mr. Lin, is this a trick to disturb the suspect's mind?"

"That's right." Lin Xin nodded:

Although the theory of the prisoner's dilemma sounds powerful, it is not easy to trap opponents in practice.

Because reality is not an ideal model after all, just like now...the three suspects should be very clear in their hearts that it is difficult for the police to find clues to solve a case that has been pending for 12 years.

In such a situation where they knew that they would be able to escape the crime with a high probability of being bitten to death, the resistance of the three of them would be much stronger.

At this time, just like what Lin Xinyi had just arranged, it was necessary to use some tricks to disturb the enemy's mind.

Although this kind of trick is simple and crude, it cannot be studied carefully.

But for a person under trial who is already under enormous psychological pressure, it can have a great effect.

"By the way... In addition to interrogation, other investigations must not be relaxed."

"Although the investigation is very difficult after 12 years, we still have to actively visit the island residents who have impressions of the case back then to see if we can find clues to help solve the case."

"It would be great if we could find some useful evidence."

After carefully arranging everything, Lin Xinyi opened the curtain for the action:

"Then, let's start the interrogation now!"

...............................

Soon after.

Moon Shadow Island Village Office, in the interrogation room temporarily requisitioned.

Takeshi Nishimoto, a middle-aged man with disheveled hair, wrinkled clothes, and a somewhat scruffy appearance.

At this moment, facing Lin Xinyi as the interrogator, his reaction was very ugly:

His eyes are evasive, not daring to look at people.

The eyebrows were drawn down, and the lips were pursed tightly, as if he was afraid, but also seemed to be thinking.
