Three hours later, Kasumigaseki, Metropolitan Police Department building.

In just three hours, the salvage personnel were lucky to find the documents carried by the deceased from the torn clothes on the subsequent salvage.

Based on this, the police quickly confirmed the identity of the deceased and quickly contacted the deceased's family.

After the cooperation of the deceased's family, it was confirmed that the deceased did disappear suddenly in the middle of the night last night, and left a suicide note written by himself at home.

Faced with this evidence, the police are even more convinced that the deceased died by throwing himself into the water.

In this way, the case of corpse mutilation was successfully solved.

And Lin Xinyi, Kudo, and Xiaolan, who had just cooperated with the police to complete the record, also completely got rid of the case, and they said hello to the police officers in charge of the case, and they were ready to leave.

"Brother Lin!"

Before parting, the Dusk Police Department also patted Lin Xinyi's shoulder enthusiastically with his big fat hand:

"Thanks to you this time, the case can be solved so quickly."

"If I have the opportunity in the future, I hope to cooperate more!"

The more free crime-solving tools people are, the better.

Therefore, the Twilight Police Department will not be like those young police officers, because they have been ridiculed by Lin Xinyi, they are estranged.

"Hmm..."

Lin Xinyi responded very insincerely:

He has made up his mind to change to a relaxed lifestyle, and if nothing else, he will not have any chance to cooperate with the police in the future.

However, to send the Buddha to the west, Lin Xinyi deliberately reminded the Dusk Police Department at the last moment:

"By the way, Officer Twilight."

"I also took a blood sample of the deceased's heart with a puncture needle during the on-site autopsy."

"That blood sample is now being inspected and kept by Komatsu, if possible, please ensure that the blood sample is sent to a professional identification agency for toxicology testing."

"W-What?"

Officer Twilight's chubby round face trembled:

"Blood samples sent for testing... Are you suspecting the presence of toxins in the deceased's body? ”

"But didn't the deceased die by suicide and drowning?"

"And we've all contacted her family and found her suicide note!"

Lin Xinyi's words were like a depth charge.

Officer Twilight was blown up and dazed. Detective Kudo Shinichi, who was originally busy talking and laughing with Xiaolan next to him, was also blown up and instantly forgot his childhood sweetheart:

"Mr. Lin Xinyi..."

"Did you find any evidence that I hadn't noticed?"

Kudo Shinichi bit the word "again" very hard.

But Lin Xinyi replied very calmly:

"No, not at all."

"I did not find any signs of poisoning on the body surface of the deceased, nor did I find traces of restraint injuries and resistance injuries from the deceased's wrists, forearms, etc."

"From all the evidence that can be collected so far, the deceased died by suicide."

"But, I've said it before..."

"The most taboo thing in forensics is preconceived."

"You think it's a suicide, but in fact it's probably a suicide by drowning."

"You think it's a suicide by drowning, but there may be another fact lurking behind it."

He methodically pointed out the direction of the next investigation for the Twilight Police Department:

"This time I just did a basic autopsy for the deceased, and many things are not visible to the naked eye."

"For example, the deceased may have been stunned by sleeping pills and thrown into the water to disguise suicide."

"Cases like this are not uncommon, and clues can only be found through blood tests."

"To further confirm that the deceased committed suicide, it is important not only to do a blood test, but also to do a good job of investigating whether the deceased had a motive for suicide before his death."

"If possible, an autopsy must be performed to determine whether the deceased had subcutaneous hemorrhage from injuries before death – I stressed this to you at the scene."

"Please keep the suicide note written by the deceased himself, if any suspicious points are found in the subsequent investigation, the police will still have to do handwriting identification on the suicide note."

In the end, Lin Xinyi paused slightly and said solemnly:

"As long as there is room for doubt, we must not give up our doubts easily."

"After all, our job is to find out the truth, not to rush to a conclusion and deal with the indicators."

"This..."

The Dusk Police Department blushed slightly when Lin Xinyi said it.

Truth be told, neither he nor the other police officers were relieved to learn that the deceased had died by suicide.

There is a result, the case is solved, and the pressure is gone.

Everyone just wants to get the case settled smoothly.

In this situation, without any other clues, no one will "have nothing to do" and suspect deeper.

"I see..."

"Only those who can truly understand the suffering of the deceased can always maintain this persistence in doubting to the end."

Kudo Shinichi further understood what Lin Shinichi had said before.

The Twilight Police Department nodded solemnly after some thought:

"I see, Brother Lin."

"I will send that blood sample to the scientific research institute for testing, and the body will also be entrusted to the forensic laboratory of the partner university for autopsy."

"I promise that if we find something suspicious, our Metropolitan Police Department will definitely investigate it to the end."

"That's good."

Lin Xinyi finally put his mind at ease.

Although his current identity is neither a forensic doctor nor a criminal policeman, there is no need to worry so much about the case.

But it can't be helped... The level of work shown by the Tokyo Metropolitan Police Department is really unsettling.

"Goodbye, Dusk Police."

"And Kudo, Miss Maoriran."

Lin Xin said goodbye to the few people he knew today, and prepared to leave the Metropolitan Police Department directly.

"Wait!"

Kudo Shinichi hesitated for a moment, but finally chased after him quickly:

"Mr. Lin Xinyi, I still have a question for you."

"Just ask." Lin Xinyi stopped very cooperatively.

But the young detective hesitated for a moment before carefully considering the vocabulary and said:

"Mr. Lin Xinyi."

"Someone as capable as you..."

"Why do you want to make that choice?"

“？？？” Xiaolan and the Twilight Police Department both had question marks on their faces.

But Lin Xinyi shrugged his shoulders and gave an even more incomprehensible reply: "Who knows? ”

"Then we'll have a chance to meet again in the future, right?"

The conversation between Kudo and Shinichi Hayashi is like an encrypted telegram.

I only heard Lin Xinyi reply again: "Of course, the current 'me' is already a new me. ”

After saying that, he smiled naturally, then turned around and walked out of the Metropolitan Police Department gate with strong steps.

Lin Xinyi left like this.

The Twilight Police Department also had a lot to do, so he quickly gave up thinking and went back to the office.

Only Xiaolan was at a loss for a while, and finally grabbed the corner of Kudo Shinichi's clothes curiously:

"Shinichi, what exactly were you talking to Mr. Lin just now?"

"What does it mean to come out with 'that kind of choice'? Is there anything Mr. Lin did that I don't know? ”

"Haha..."

Shinichi Kudo showed a relaxed smile:

"You really didn't see it at all, Xiaolan."

"Don't sell it!" Xiaolan clenched her fists in shame.

"Ahem... Remember the conversation we had before we found the body? ”

Kudo Shinichi cleared his throat and finally revealed the mystery:

"What is Mr. Lin doing in the park in a black suit early in the morning?"

"Also, why are his trouser legs and shoes wet?"

"Huh... Oh yes..."

Xiaolan was slightly stunned, only to realize that the problem was not simple.

Because his trouser legs and shoes were wet with water, Lin Xinyi was suspected of being a suspect at the beginning.

But now it turns out that he is not a murderer, and he has not thrown the corpse at all, so how can he get his trouser legs wet when he is so dignified?

"When I found the broken body, I immediately suspected that Mr. Lin was the murderer."

"And he rushed to the scene as soon as we found the body, which made me even more suspicious of him."

"But actually, before this case..."

"I actually have another guess about the reason why Mr. Lin got his trouser leg wet."

Kudo Shimba's voice gave Xiaolan a brief time to think.

Seeing that Xiaolan still hadn't guessed the answer, he continued to remind:

"You know, we also smelled a strong smell of smoke from Mr. Lin at that time."

"He was sorting out the things in his pocket at the time, and I saw an empty cigarette box in his pocket."

"By all indications, he's been smoking a lot of cigarettes lately, but his fingers are clean – people who smoke a lot of cigarettes often have a noticeable burnt yellow mark between their index and middle fingers."

And at the same time, I noticed the phone he was holding:"

"There is a lot of dirt between the cracks of his mobile phone keyboard, which is a manifestation of the owner's sloppy living habits, lack of personal hygiene, and unkemptness."

"But if you look at it today, the suit on his body has been meticulously tied, the neckline and cuffs are not messy at all, and his hair and face are also cleaned."

Shinichi Kudo has almost already given the answer:

"Why would a person who doesn't usually smoke much smoke so much?"

"Why would a person who is usually unkempt suddenly clean himself up so cleanly?"

"It's... Don't? ”

Xiaolan covered her mouth in surprise.

She had a terrible guess in her mind.

"That's right."

Looking at the direction in which Lin Shinichi disappeared, Kudo Shinichi sighed softly:

"Mr. Lin Xinyi is the same as the lady who died."

"He went to kill himself."

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

Leaving the Metropolitan Police Department alone, thinking of the worried gaze of Kudo Shinichi just now, Lin Shinichi couldn't help but recall his experience when he first arrived here:

When he crossed over in the morning, he opened his eyes and found himself standing in the cold river in a daze.

Soon, Lin Xinyi faintly realized the intention of the original owner to appear here, so he quickly went ashore to find a park bench to sit down, and began to look for clues from his body that could help him further understand "himself".

Then, it was his chance encounter with Kudo Shinichi and Mao Lilan.

"That detective is also quite interesting."

Thinking back to the experience at that time, Lin Xinyi couldn't help but smile:

"He pestered me to ask me questions at that time, in fact, he wanted to confirm my mental state and prevent me from jumping into the river again, right?"

"Heh, that's a nice guy..."

"As you say, I hope we will have a chance to meet again in the future."

Lin Xin thought about it for a while, and added a premise in his heart:

"Uh... As long as it is not at the scene of the crime. ”
