Coroner Coroner

"Otherwise, he wouldn't even be able to deal with it so awkwardly and reluctantly, even Councilor Oki, who was fatally injured and whose strength was reduced to nine out of ten."

The murderer succeeded in backstabbing at the very beginning, but was dragged into a tangled struggle by the seriously injured Mr. Oki.

This shows that his own fighting power is really unsightly.

"The evidence doesn't stop there..."

Lin Xinyi pointed to the photos of Mr. Oki's head and face wounds, and added:

"The deceased's head and face had multiple injuries caused by blunt blows with sticks."

"These injuries look serious, but they didn't hurt the bones, they were just superficial flesh injuries."

Councilor Oki's head was beaten to pieces, and his head was bloodied. It looked bloody and bloody, but in fact, the damage was limited, only the flesh was injured.

And the murderer came to kill people at that time, so he would definitely not show mercy.

Since the murderer tried his best to hit the dead man's head with a stick repeatedly repeatedly, it still only caused such a limited degree of damage.

That just means...

"He has very little strength."

"Even if he hit the deceased's head with a wooden stick with all his strength, he still failed to injure the deceased's skull."

Lin Xinyi slowly came to a conclusion:

"This murderer is a guy with extremely low individual ability."

"Leaving aside the small probability factors such as disease, premature aging, developmental delay, and malnutrition, in general criminal cases, this often means:"

"The murderer is a minor, or an old man."

"So that's how it is..." Officer Jiang Gu quickly understood Lin Xinyi's meaning:

On the night of the incident, the hotel in the twin tower skyscrapers had not yet opened.

Living in that hotel, the only people who have the best chance of attacking Senator Oki are Tokiwa Mio, Kizuki Mine, and the employees of Tokiwa Company.

And among these, the others were in the prime of life.

Only Ruyuefengshui is a 60-year-old man who has to walk with a cane, which meets the characteristics of "low physical fitness".

Therefore, this well-known old painter is undoubtedly the number one suspect in this case.

"But…"

Police officer Jianggu followed up with a but:

"The identity of this old Mr. Ruyue Fengshui is just the ancient painting teacher of Chairman Toki Pan."

"He and the deceased Councilor Oki were only introduced by Chairman Tokiwa on social occasions, and they met each other as nodding acquaintances."

"The two sides can't talk about any friendship, and there is no exchange of financial interests."

"For Kisaragi Mine, it seems that he has no motive to kill Representative Oki at all."

"This..." Lin Xinyi spread his hands helplessly: "I can't explain the motive."

He has gradually gotten used to it now, and he doesn't really investigate the case from the motive of killing.

Because the murder motives of some murderers in this world are really weird:

Last time, Zemu Fair just turned into a self-destruct truck and blew up a water crystal building just because a rich man who had nothing to do with him spent his own money ruining his precious wine.

How does this make people check their motives?

Whoever understands this motivation is not far from a bed in a mental hospital.

"Anyway..."

"Let's put motivation aside."

Lin Xinyi skipped this topic.

But at the same time, he understands Jiang Guling's doubts:

"Because there is no motive for the murder on the surface, so even if there is suspicion on Ru Yuefeng Shui, the suspicion must be greatly discounted."

"And the security facilities of the twin-tower skyscrapers are extremely poor, and the possibility of outsiders sneaking in to commit crimes cannot be ruled out at all."

"So, to be on the safe side, we have to consider:"

"This murderer with low physical fitness may not be Ru Yuefeng Shui, but a mysterious person who sneaked in from the outside world."

This mysterious person may or may not exist.

And since the police can't find out the motive of killing the number one suspect, Ru Yuefengshui, they must consider more carefully the possibility that the mysterious person is real.

"But I have one more proof:"

Lin Xinyi paused slightly, and emphasized in a serious tone:

"This evidence can further aggravate the suspicion on Ru Yuefeng Shui."

"And this evidence is... the murder weapon!"

He pointed his finger at the close-up photo of the head of the deceased Mr. Oki again:

"The hollow subcutaneous hemorrhage injury on the left temporal part indicates that the murder weapon used by the murderer to attack the head of the deceased was a blunt weapon like a stick."

"The deceased had multiple injuries on the head and face, most of which were simple skin peeling and skin bleeding."

"The bleeding was relatively mild and the boundaries were not very clear."

"In addition, the murderer hit the deceased's head several times with all his strength with a stick, but failed to break the skull and cause bone damage."

"This incidates that"

"The murderer used a regular, slender, smooth-surfaced wooden club, not a metal club."

Lin Xinyi first presented evidence and determined the material type of the object that caused the injury.

Then, he said in a more emphatic tone:

"The deceased had a 12cmx2cm hollow subcutaneous hemorrhage in the left temporal region."

"Attention, this 2cm."

2cm is the width of the stick scar.

The sticks will be slightly wider than this, but not by much.

"In order to ensure the lethality and ease of use, generally the wooden sticks that can be selected by murderers as murder weapons are relatively strong and thick."

"So in cases where a wooden stick is used as the murder weapon, the width of the blow wound is generally more than 3cm."

"And in this case, the width of the wound on the deceased was only 2cm."

"This shows that the wooden stick used by the murderer is different from ordinary stick-like murder weapons, and its shape is relatively slender."

"Hmm..." Officer Jiang Gu nodded slightly.

He seems to have quietly realized something:

Just listen to Lin Xinyi continue to explain:

"In addition to the dagger used in the sneak attack at the beginning, the murderer also used wooden sticks when he entangled in the fight."

"But Officer Jianggu, do you still remember what happened when we investigated the case last time?"

"That's when we discussed:"

"Generally, when a murderer comes to commit a crime, he will only carry a weapon that is convenient for him."

"If there is a second weapon, it is often the murderer."

"The scene of the crime is a private room in a luxurious hotel where Senator Oki lives."

"How can there be such a regular, slender, smooth-surfaced cylindrical wooden stick in such a high-end hotel room?"

Of course there is no such thing as a wooden stick in a hotel room.

The stick was not taken by the murderer from the scene.

It was brought to the scene by the murderer himself.

So, here comes the question:

"Why did the murderer in this case carry two weapons?"

"Could it be because he expected that he would not be able to deal with Mr. Damu with a dagger, so besides the dagger, he had to bring another stick for self-defense?"

"But if it's for this reason..."

"Ordinary people would not choose to carry something like a wooden stick, which is too long, inconvenient to carry, and has limited lethality, as their own self-defense weapon?"

"Bring a dagger, or a weapon like a hammer or scissors. Isn't it better than a wooden stick?"

"And most importantly..."

Lin Xinyi asked several key questions one after another.

On this last question, he quietly aggravated his tone:

"The dagger fits perfectly in the bosom, but not the slender stick."

"And the murderer entered the scene peacefully as an acquaintance, and then took advantage of people's unpreparedness to wait for an opportunity to sneak attack."

"But at that time, he was holding such a slender and conspicuous wooden stick in his hand."

"Will this not be seen by Mr. Oki?"

"Since Senator Damu saw this wooden stick that could be used as a murder weapon, why didn't he become alert and let the murderer succeed in a sneak attack?"

"This..." Jiang Gu Zero smiled, "I understand."

Lin Xinyi's reminder made him think through everything in an instant:

"Because that wooden stick has other uses, it was not brought into the scene by the murderer as a self-defense weapon."

"So even if Mr. Damu sees this wooden stick, he won't be suspicious."

"after all…"

Jiang Guling paused slightly.

His gaze, and Lin Xinyi's gaze, both focused on that photo.
