Hearing this, even if he is not very good at reasoning, Sonoko can understand the dilemma Kudo Shinichi is facing at this moment:

The tactics can be seen through at a glance, but there is no physical evidence that can identify the murderer.

He wore latex gloves and did not leave any fingerprints at the scene.

After killing the man, he threw the gloves into the toilet and flushed them. There was no chance of collecting skin flakes from the items he left behind.

Looking around, except for a few bloody fingerprints without fingerprints, the naked eye could not find any shoe prints, palm prints or other useful traces.

"In that case..."

Seeing that Kudo was in trouble, Suzuki Sonoko couldn't help but look forward to her idol's answer:

"Mr. Lin Xinyi, what do you think of this case?"

"Huh?" Lin Xinyi, who had been silent, finally responded.

He had just been staring down at the corpse and the blood-stained floor, as if in a daze.

But now, when she raised her head, Yuanzi suddenly discovered...

There was no trace of confusion in Lin Xinyi's eyes:

"What Kudo just said is very accurate."

"Although the possibility of deliberate murder cannot be completely ruled out."

"But judging from the current clues, it is more likely that the robbery and murder were impromptu."

Lin Xinyi began by characterizing the case.

Although his words were chosen more carefully, in the final analysis, the meaning he expressed was exactly the same as Kudo's.

It’s just that Kudo likes to start from clues on the scene, and he is more accustomed to observing corpses:

"After preliminary inspection, there are only two visible injuries on the deceased's body:"

"The first place was a small area of ​​subcutaneous bleeding on the back of the neck, which was caused by external force."

"This form of attack on the back of the neck shows that the murderer did not intend to kill at the beginning, but just wanted to make the deceased unconscious."

"So Kudo is right, this case is most likely a robbery."

Through the scars on the deceased's neck, Lin Xinyi confirmed Kudo's inference about the case.

Then, he gave Suzuki Sonoko a meaningful look:

"Speaking of which, the injury on the deceased is very similar to the bruise on your neck, Miss Suzuki."

"She must have suffered the same attack as you."

"But unfortunately, this lady is not as alert as you."

"She was not knocked unconscious by the murderer's blow, nor was she knocked unconscious by fashion like you, Miss Suzuki, but..."

Suzuki Sonoko: "..."

She felt a chill run down her spine.

It seems that the deceased had the same experience as her. They both went to an unoccupied bathroom to put on makeup, and were attacked on the back of the neck.

But she reacted in time and pretended to faint.

Otherwise, I am afraid she would be brutally killed by the murderer in this bathroom just like the deceased.

"Fortunately...fortunately."

Suzuki Sonoko whispered with some fear.

Lin Xinyi continued to elaborate on his thoughts and findings:

"The second injury was an oblique wound located on the xiphoid process of the chest. The wound edge was neat, the wound wall was smooth, there was no inter-tissue bridge in the wound cavity, and the wound angle was blunt and sharp."

"This was an apparent stab wound with a single-edged sharp instrument."

"Judging from the deceased's pale skin and fingernails on both hands, as well as the amount of bleeding in the chest and abdomen..."

Lin Xinyi moved his gaze to the chest and abdomen of the deceased, which was completely stained red with blood:

"Judging from the angle of entry of the knife and the length of the murder weapon... the knife should have cut the pericardium, ruptured the inferior vena cava, entered the right chest cavity and pierced the lungs, eventually causing hemorrhagic shock and death.

.”

After saying this, Lin Xinyi directly summarized the clues and reviewed the case process:

"Based on existing clues, it is speculated that the murderer was probably waiting for the train at the platform when he saw the deceased entering the bathroom alone to put on makeup."

"Because the deceased was fashionably dressed and well-groomed, and looked like a wealthy man."

"The bathroom is under maintenance and no one is entering or leaving, so it is more suitable for committing crimes."

"So the murderer made an impromptu decision and quietly followed the deceased into the bathroom, intending to attack the neck from behind to knock the deceased unconscious, and then rob her of property."

"But...the deceased was not knocked unconscious as easily as the murderer imagined."

"Not only did the deceased not faint, but he was still awake and ready to call for help, and even resisted."

"This makes the murderer very nervous - because the platform is full of people outside, and if he makes any noise, he will be discovered immediately."

"So, in order to control the situation in time...the murderer took out the short knife he carried with him and stabbed the lady in the chest without hesitation."

Lin Xinyi took a deep look at the lady who died tragically in a pool of blood:

"For such a simple and ridiculous reason..."

"A young life has been lost."

Seeing too many cases will always make people lament the fragility of life and the impermanence of fate.

Suzuki Sonoko felt the sentimentality shown by Lin Xinyi, and couldn't help but become quiet.

But, after a brief moment of silence...

"etc..."

Suzuki Sonoko suddenly reacted:

"Isn't this similar to what Kudo just said?"

Although the way of telling is different and the way of discovery is also different, what Lin Xinyi is talking about now is nothing more than repeating Kudo's reasoning.

In fact, there were some places that he didn't go into detail enough with Kudo.

For example, Kudo also confirmed through bloody fingerprints and small blood drops that the murderer was wearing latex gloves, and knew that the murderer went to the toilet stall after killing the person and flushed the gloves down the toilet.

In contrast, Lin Xinyi's reasoning focuses more on restoring the details of the deceased's life experience and describing the pain the deceased suffered, but...

After talking about it for a while, the most critical issue has never been solved:

"How to find out the identity of the murderer?"

Suzuki Sonoko asked in confusion, and Kudo Shinichi also cast a curious look.

"It's very simple."

Lin Xinyi answered very lightly:

"The murderer is stained with the blood of the deceased. All he needs to do is find the one with the blood on him."

"Isn't this...impossible?"

Kudo Shinichi immediately raised objections:

"There was no clothing left at the scene, indicating that the deceased escaped directly wearing the clothes he wore when he committed the crime."

"If blood splatters and gets on his body, how can the murderer blend into the crowd wearing blood-stained clothes?"

"And if the blood didn't splash and just flowed along the blade..." "The murderer's hands were covered by gloves. As long as he paid a little attention, there would be no blood on his body at all."

"No... having gloves to block it just makes the possibility of getting blood very small."

"But that doesn't guarantee there won't be."

Lin Xinyi retorted in a similar way.

"Forehead..."

Kudo was speechless:

Indeed, there is no guarantee that it will not happen.

Then try to look for them, maybe you will find someone with blood on them.

There is nothing wrong with this idea, but...

This is more like trying his luck, and does not show the technical level that Lin Xinyi should have.

If you are unlucky and don't bump into it...then you will have to waste the effort of checking more than 100 people.

And those are more than 100 impatient Tokyo citizens. If they can stay here now, they are already giving face to Mao Lilan's fist.

But after all, Xiaolan would not take action, and those passengers would never wait there obediently, letting the investigators think of a way to come over and try to investigate.

If it drags on for too long and more than 100 citizens gather to make a fuss, even the Metropolitan Police Department will have to let him go.
To be continued...
