Coroner Coroner

The technique can be seen at a glance, but there is no physical evidence that can lock the murderer.

He was wearing latex gloves and there were no fingerprints left at the scene.

After killing the man, he threw the gloves down the toilet and flushed it, and there was no chance to collect dander from the items he left behind.

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

"In that case..."

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

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

"Huh?" Lin Xinyi, who had been silent for a while, finally reacted.

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

But now, looking up, Sonoko suddenly found...

Lin Xinyi's eyes were not at all dazed:

"What Kudo just said is very accurate."

"Although intentional murder cannot be completely ruled out."

"But from the current clues, it is more likely to be a temporary robbery and murder."

Lin Xinyi started by defining the case first.

Although his words were more cautious, in the final analysis, the meaning of his words was exactly the same as that of Kudo.

It's just that Kudo likes to start from on-site clues, and he is more used to observing corpses:

"After a preliminary examination, there were only two visible scars on the body of the deceased:"

"The first is a small area of ​​subcutaneous hemorrhage at the back of the neck, which is caused by external force."

"This type of attack on the back of the neck shows that the killer did not intend to kill in the first place, but just wanted to make the deceased unconscious."

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

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

"She should 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, nor was she stunned in time like you, Miss Suzuki, and as a result..."

Suzuki Sonoko: "..."

She heard a chill down her spine.

The deceased said that it was the same as her experience. They all went to the bathroom where no one was going to put on makeup, and they were all attacked on the back of the neck by someone here.

It's just that she reacted in time and pretended to faint.

Otherwise, she would probably be brutally murdered in this bathroom by the murderer just like the deceased.

"Fortunately...fortunately."

Suzuki Sonoko muttered softly with some fear.

And Lin Xinyi continued to explain his own ideas and findings:

"The second injury is an oblique wound located at the xiphoid process of the chest. The wound margin is neat, the wound wall is smooth, and there is no bridge between tissues in the wound cavity. The wound angle is blunt and sharp."

"It was a clear single-edged sharps stab wound."

"And judging from the pale skin and fingernails of the deceased, as well as the amount of bleeding in the chest and abdomen..."

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

"From the perspective of the knife, and the length of the weapon... The knife should have cut the pericardium, causing the inferior vena cava to rupture, entering the right thoracic cavity and puncturing the lungs, eventually causing hemorrhagic shock and death."

After saying this, Lin Xinyi directly summed up the clues and restored the case process:

"According to the existing clues, it is speculated that the murderer is likely to see the deceased person who entered the bathroom alone in order to put on makeup while waiting for the bus at the platform."

"Because the deceased was dressed stylishly and well-dressed and looked like a rich man."

"And the bathroom is being repaired and no one comes out, which is more suitable for committing crimes."

"So the murderer made up his mind and quietly followed the deceased into the bathroom, preparing to attack the back of the neck from behind to stun the deceased, and then rob her of property."

"But... the deceased was not as easily stunned as the murderer thought."

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

"It made the murderer very nervous - because the outside is a platform where people come and go, and if there is any movement, he will be found immediately."

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

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 is lost."

Seeing a lot of cases will always make people sigh at the fragility of life and the impermanence of fate.

Suzuki Sonoko felt the kind of sentimentality that Lin Xinyi showed, and could not help but become quiet.

But, after a brief quiet...

"and many more…"

Suzuki Sonoko suddenly reacted:

"Are these similar to what Kudo just said?"

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

Even, in some places, he hadn't explained the details of Kudo.

For example, Kudo also confirmed through blood fingerprints and small blood droplets that the murderer was wearing latex gloves, knowing that the murderer went to the toilet cubicle after killing people and flushed the gloves into the toilet.

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

After some talk, the most critical problem has never been solved:

"How to lock the identity of the murderer?"

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

"It's simple."

Lin Xinyi replied very lightly:

"The murderer got the blood of the deceased, just find the one with blood on his body."

"That's not possible, is it?"

Kudo Shinichi immediately objected:

"No clothes were left at the scene, which means that the deceased escaped directly wearing the clothes he used to commit the murder."

"If the blood splattered on the body, how could the murderer get into the crowd wearing this blood-stained clothes?"

"And if the blood doesn't splatter, it just flows down the blade..." "The murderer has gloves on his hands. As long as he pays a little attention, his body won't get blood at all."

"No... There are gloves to block it, it just makes the possibility of blood stained 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 there will be none.

Then try to look for it, maybe you will find one with blood on her body.

There's nothing wrong with this idea, but...

This is more like hitting luck, not showing the technical level that Lin Xinyi should have.

If you are unlucky and don't hit it... then you will have to waste your efforts to investigate more than 100 people.

And those are more than 100 impatient Tokyo citizens. They can stay here now, which is already giving Maurilan a fist face.

But Xiaolan wouldn't really do it after all, and those passengers would never wait there honestly, so that the investigators thought of a way to come over and try to investigate.

If the time drags on for a long time, more than 100 citizens will gather in a crowd and make a commotion, even the Metropolitan Police Department will have to obediently let them go.

Therefore, it is necessary to come up with an accurate and effective investigation method as soon as possible.

Kudo was thinking so.

But then, unexpectedly, Lin Xinyi immediately added evidence for his point:

"The possibility of getting blood is there."

"And I can prove that the murderer must have the blood of the deceased on his body."

"Look at those little blood droplets on the ground—"

With that said, Lin Xinyi pointed his finger at the long string of small blood droplets on the ground.

These little blood droplets spread from the lodging place of the dead body to the toilet cubicle where the murderer abandoned the knife.

Obviously, as Kudo reasoned, this was the blood dripping from the murderer's knife on the way to the toilet cubicle after killing people.

But Lin Xinyi saw more things from these small blood droplets:

"This kind of blood drop is called dripping blood in trace science."

"The so-called drip-like blood stains are blood stains formed by the blood dripping onto the surface of an object under the action of gravity."

"This bloodstain is generally circular or quasi-circular."

"However, in most cases, the surface of the object on which the blood dripped was not smooth."
