Coroner Ke Xue

Yusuke Sakata admitted his crime.

He also revealed his motive for the murder:

It turned out that his father used to be a driving school instructor with strict teaching.

The deceased, Nagao, Nishiguchi, Noyasu, and three others were students in a driving training class that Sakata's father was responsible for twenty years ago.

These six "bad students" were dissatisfied with Coach Sakata's serious and strict teaching attitude, so they conspired to pull off a very bad prank:

They deliberately got Coach Sakata drunk at the dinner table, and then allowed Coach Sakata, who was already unconscious, to drive home after drinking.

They even tampered with the brakes to make it harder to stop the car.

Let a drunk person drive a car that has been tampered with, and the result will naturally be a tragedy.

Sakata Yusuke didn't know about this at first.

But among those six people, one of them happened to be a serial murderer on the run twenty years later.

When Officer Sakata was chasing the murderer, he learned the truth from him.

So he secretly imprisoned the murderer, and began to retaliate and liquidate his enemies such as Nagao, Nishikou, and Yean.

"I originally planned to kill the other five people and then put the blame on the fugitive murderer."

"He was one of the six people who killed my father that year. He knew Nagao, Nishiguchi and others. The police will definitely give priority to suspecting this 'roving murderer'."

"It's a pity that all my plans are of no use now."

Sakata Yusuke sighed helplessly.

"Manager Lin, you are right."

"As a police officer, I betrayed the trust of the people and committed an unforgivable crime."

"But...I don't regret it!"

He gritted his teeth and said:

"It was those six bastards who conspired to kill my father."

"The law can no longer punish them, so I can only punish them!"

Lin Xinyi: "."

Looking at the murderer with tears in his eyes, he remained silent and did not speak.

In traditional moral concepts, it is natural for a son to avenge his father.

It can be understood logically.

But there are no rules. As a law enforcer, Lin Xinyi must clearly oppose this kind of criminal behavior:

"Bring Officer Sakata away."

"Everyone has to pay for what they do."

"Since you have chosen this path, please take responsibility for it."

The police officers swarmed over.

Yusuke Sakata also completely gave up resistance and surrendered.

This serial murder case that shocked Osaka came to an end.

"well"

Watching Sakata Yusuke being escorted away, Hattori Heizo sighed lightly.

Immediately afterwards, the head of the provincial police headquarters, who was dignified in his bones, quietly cast a friendly look at Lin Xinyi:

"Manager Lin, thank you."

"If it hadn't been for you, I'm afraid more citizens in Osaka would have been harmed."

"It's just a matter of duty." Lin Xinyi replied casually.

He is not good at making polite remarks, nor does he like to get close to others.

What's more, he is still an undercover agent who always wants to give up and leave, and has no ambitions for career development.

Therefore, even when faced with Hattori Heizo, a super leader who can be called "Osaka Qi Tongwei" (the top leader of the provincial police), Lin Xinyi can neither be humble nor overbearing.

Hattori Heizang's eyes were filled with admiration.

He has a very strong aura, and when young police officers see him, they often appear reserved and nervous.

But Lin Xinyi was able to talk to him as an equal without being humble or arrogant.

“Talented people are just different.”

"It seems that I really invited the right person when I asked you to come to our Osaka to be our guide."

To the ears of the Osaka Prefectural Police officers around him, it was like his father praising "someone else's child" again.

But now they will no longer have any opinions.

Because Lin Xinyi has proven his strength:

It only took him one meal to solve the serial murder case that troubled the Osaka Prefectural Police.

What's even more embarrassing is that the murderer is one of their own - this is a huge embarrassment to the Osaka Prefectural Police.

"Forest Manager."

Under the helpless admiration of his subordinates, Hattori Heizo continued to release his enthusiasm and kindness to Lin Xinyi:

"Although the case has been solved, it is a rare time for everyone to come to Osaka. It would be a pity to go back without having fun for two days."

"If you don't mind, can you stay at my house today?"

"I also want to talk to you about something."

In the evening, Hattori's house.

Walking into this Japanese-style mansion that makes it difficult to tell whether it is a manor or a wilderness. The courtyard is decorated like a scenic spot. Lin Xinyi knew even more clearly:

Hattori Heiji was more than just a back wave, it was a tsunami.

But at this moment, this enviable winner in life was helplessly enduring the lecture in front of his father:

"Heiji, this incident should have made you more awake, right?"

"You always underestimate the work of the police because of your talent and arrogance, but compared with our forest management officer, you still have a lot to learn."

Hattori Heizang educated his son with great care.

Lin Xinyi had previously become "other people's children" that he used to stimulate his subordinates, and now he used this example on his own son.

"Dad, I know what you're going to say."

Hattori Heiji contradicted unconvincingly:

"Don't you just want me to give up the idea of ​​being a detective, take over from you, and become a policeman?"

"That's impossible. No matter what, it's my dream to be a detective!"

"Haha." Lin Xinyi laughed slightly at the side.

He knew why the Hattori Headquarters invited him to his home as a guest.

The purpose was to have him speak out and help convince Hattori Heiji to give up his dream of being a detective and change his career to become a police officer.

Dreams are worthy of respect.

But Lin Xinyi prefers to start from reality:

"It may sound ugly to say it, but the detective profession will be eliminated by the times sooner or later."

"At least, in the future, the investigation of front-line criminal cases will be fully police-led."

Under the appreciative and expectant gaze of Hattori Heizo, Lin Xinyi naturally expressed his expectation:

"As long as the police can truly and effectively use the power of criminal science and technology, there will be no case that requires the help of detectives."

"Mr. Lin, I know what you mean."

Hattori Heiji insisted on his own philosophy tit for tat:

"Through the exchanges with Miss Maori these days, I also know the role that criminal science and technology can play."

"But the police can use this knowledge and technology, but can't detectives use it?"

"I'm always learning too"

"What you know, I, as a detective, can definitely learn."

"No, you still got it wrong."

Lin Xinyi shook his head and sighed:

"The promotion of criminal science and technology means that the division of criminal investigation procedures will become more detailed and standardized."

"Solving crimes will increasingly rely on collective strength rather than individual wisdom."

"For example"

He paused slightly, then smiled and asked about Hattori Heiji:

"Mr. Heiji, do you think you can survey the scene by yourself?"

"This" Hattori Heiji was speechless for a moment.

In the past, crimes were solved by detectives who went to the scene and scanned the scene with their naked eyes.

Then miraculously, it was like turning on ‘Witcher Vision’ with one click——

Those key clues to solve the case will always pop into the eyes of the famous detective at just the right time.

This relies more or less on metaphysics and luck.

But in fact, surveying the site is a huge workload.

To do this job well, multiple police officers are required, carrying various professional equipment such as multi-band light sources, electrostatic adsorbers, and luminol reagents, to search for traces inch by inch in the area.

Among them are forensic personnel, trace inspection personnel, and professional on-site photographers——

Don’t think taking pictures is easy.

On-site surveys often require special photography skills. The shooting methods include one-way shooting, opposite shooting, multi-directional shooting, rotational segmented shooting, linear segmented shooting, and proportional shooting.

Crime scene photography itself is also a profession that requires a lot of research.

"You said you could learn criminal science technology."

"Forensic medicine, trace examination, on-site photography, there are so many majors, how many can you master by yourself?"

"Even if you can learn it, can you do all this work by yourself?"

"This is it"

Hattori Heiji said awkwardly:

"Let the police officers from the forensics department be responsible for the on-site investigation."

"As a detective, I only need to make inferences and analysis based on the results of their investigation."

"good."

Lin Xinyi did not refute, but continued to ask:

"Then have you ever thought about whether you can complete the most basic interview and investigation work alone?"

Interviews and surveys sound easy, but in fact the workload is huge.

Police officers sometimes need to visit surrounding residents on a large scale near the scene, often checking dozens or hundreds of households.

"I definitely can't do this alone."

Hattori Heiji answered calmly:

"In the past, officers from the Osaka Prefectural Police would help with this kind of work."

"Um."

Lin Xin nodded and asked again:

"Solving crimes sometimes requires large-scale road surveillance, spending dozens or hundreds of police personnel to watch the video frame by frame."

"What are you going to do alone?"

"This" Hattori Heiji shook his head and smiled bitterly: "For road monitoring, we need the help of the police from the Prefectural Police Traffic Department."

"For security monitoring, police officers from the Search Section 1 must be responsible for conducting investigations."

"Okay." Lin Xinyi continued to ask: "I have collected the physical evidence, and I still need to take it for appraisal."

"And the major task of identification alone is divided into:"

"Department of Forensic Medicine (body fluid, tissue identification, DNA identification)"

"Electrical Department (Electrical Accidents, Fire Causes, Voiceprints)"

"Mechanical Department (Mechanical Accidents, Causes of Traffic Accidents, Identification of Firearms and Swords, Identification of Traces)"

"Document Appraisal Department (Document and Currency Appraisal)."

"Department of Psychology (polygraph detection, intelligence examination, personality examination, dialect identification, linguistic psychology)"

"Department of Chemistry (gases, gunpowder, oils, poisons, drugs, organic solvents)"

He calmly listed a long list of different types of appraisal work.

Each of these jobs requires corresponding professionals.

"Still the same question, with so many professional contents, how many can you learn by yourself?"

"As a detective, if you get physical evidence, can you complete the identification yourself?"

Lin Shinichi kept asking questions, and Hattori Heiji answered bravely:

"This is the work of Kesouyan."

"Just leave the appraisal work to the appraisers from Kesouyan."

At this point, he was almost speechless.

Lin Xinyi summed it up loudly and asked:

"do you understand?"

"If you want to solve the case, you need external investigation from the search section, investigation from the forensics section, appraisal from the scientific search institute, as well as assistance from multiple departments such as traffic and roads, household registration management and so on."

"The police do most of the work of solving crimes."

"And you are only responsible for one part, that is, the central coordination."

Lin Xinyi paused for a moment and then asked Hattori Heiji a soul-like question:

"In that case."

"Then Mr. Heiji, you are a good detective. What is the difference between you and a 'police detective'?"

"I" Hattori Heiji was completely stupid:

yes

If the police had to do all the work.

So is there any difference between being a detective and a police officer?

Quietly, Hattori Heiji's dream was shattered.

The second update will be much later
