Chapter 442 Ke Xue’s Reasoning
The so-called "wooden stick weapon" is a cane.
Knowing this can explain many problems:
The murderer did not deliberately bring a long and awkward stick with him, but he usually carried a cane with him.
Because of this, Representative Ohgi did not become suspicious when he saw the "murder weapon" carried by the murderer.
"And what if the murderer is some kind of 'mysterious person' who sneaked in from the outside world."
"If this mysterious man sneaked into the building unknowingly, I'm afraid he wouldn't have brought a weapon like a stick, which is both intrusive and difficult to use."
"This further proves that the murderer is Ruyue Fengshui who can't be taken away from him, rather than some mysterious person from the outside world."
After analyzing this, the identity of the murderer can basically be determined.
So
"How to find evidence that he is the murderer?"
Unknowingly, Officer Fangtani still forgot the purpose of his visit.
He was no longer anxious to wonder whether the Yuan Jiaming case was related to the organization. Instead, he was quite concerned about ways to bring justice to the deceased and let the murderer be punished:
"We came to this conclusion to a certain extent by relying on the criminal profile deduced from the traces at the scene."
"These more inferential clues alone may not be enough to convince Mr. Ruyue Fengshui to plead guilty."
Jiangu Ling talked about the biggest problem at present:
Ruyue Fengshui is indeed the number one suspect, but the police still lack the evidence to convict him.
"This" Lin Xinyi frowned quietly when he heard this question.
He did not give a direct answer, but carefully looked at Ruyue Fengshui in the photo and the crutch in his hand.
Old people are nostalgic, and this crutch looks very old at first glance.
The armrests looked like they were being polished and patinated.
As for the bottom of the crutch, it is the part that often comes into contact with the ground, walls, and curbs.
The wood paint covering it had already peeled off bit by bit, revealing the cracked wood inside.
"This crutch."
"Do you still have Ruyue Peak Water in your hand?"
Lin Xinyi asked thoughtfully.
"It should still be in his hands."
"This file photo of a person holding a cane was taken by the police officers we sent to investigate and interrogate Ruyue Fengshui at the scene."
Jiangu Ling gave an affirmative answer.
He also understood what Lin Xinyi meant by asking this question:
"Mr. Lin, do you want to find evidence from this crutch that Ruyue Fengshui committed murder?"
"But the problem is that since he dared to leave the crutch as one of the murder weapons in his hand after committing the crime, he should have cleaned up the traces on it."
Two days have passed since Representative Oki's death.
These two days were enough for Ruyuefengshui to clean the murder weapon.
Unless he is a fool, he will not keep a cane with the blood of the deceased in his hand.
"But we can try our luck."
Lin Xinyi pointed to the crutch in the photo and said:
"see it?"
"The cane has paint peeling off at the bottom and there are still gaps on the exposed wood surface."
"When the murderer used the crutch to hit the deceased on the head during the struggle, he would probably use the most convenient way to hold the top of the crutch with his hand and use the bottom part to attack."
"This means that the bottom of the crutch had been in direct contact with the head wound of the deceased, and it would definitely be stained with the blood of the deceased."
"The blood will most likely seep into the gaps in the wood and soak into the inside of the crutch."
"If this is the case"
Lin Xinyi paused slightly and emphasized:
"Then the blood inside the wood cannot be cleaned by ordinary cleaning methods."
Cracks in the floor, cracks in bricks, cracks in knife handles, and cracks in wood, these inconspicuous gaps in life have always been the focus of forensic medicine.
And those murderers think they can clean the physical evidence, but in fact they often only clean the surface.
like this crutch
"If you just wipe the surface, the blood stains inside the wood will not be contaminated."
"Unless he soaked the entire crutch in chemical reagents for a long time, it is basically impossible to clean the blood that soaked into the inside of the wood."
"So, we can try our luck."
"Perhaps we can detect the blood of the deceased Representative Oki from Kisaragi Fengshui's crutches."
Lin Xinyi's voice was full of confidence.
He believed that the old man Ruyue was not that smart or cautious.
After all, if he was really cautious enough, he would have thrown away the bloody cane or burned it clean.
But Ruyue Fengshui just kept the crutch in his hand.
This shows that he is too "confident".
And once people are overconfident, they will neglect details.
"Officer Furuya, inform your colleagues."
"Let them control Ruyue Fengshui as soon as possible, and then send his crutches to Kesouyan for blood stain identification."
Lin Xinyi's tone was very firm.
But after hearing his plan, Jiang Guling was a little hesitant:
"Isn't it a bit reckless to go to Ruyue Fengshui for a showdown now?"
"If the other party really cleaned the murder weapon thoroughly and no blood was detected in the crutch, then..."
Then we can only spread our hands and let him go.
Moreover, after such a sudden attack, the other party will definitely become vigilant and be a hundred times more cautious than before.
It would be difficult to find a breakthrough from him.
"Uh" Lin Xinyi was speechless.
He also understands the risks involved.
But now no one can think of any other way. What else can we do if we don't try our luck?
At least, it seems now that the police have a good chance of winning in this bet.
It's not a bad idea to take the risk and take a gamble.
Lin Xinyi originally thought so.
But when Officer Jianggu said it with such solemnity, he couldn't help but become a little confused:
"Apart from trying luck, is there any other way?"
He lowered his head and thought for a while.
As he thought about it, his expression quietly became weird.
He does have an idea.
Moreover, he came up with this method in a matter of seconds without spending much thought at first.
"Well, let's do that."
Lin Xinyi hesitated several times, and finally spoke in a subtle tone:
"We'll just wait and see."
"Anyway, Ruyue Fengshui has left the crutch 'confidently', so he must believe that he has cleaned up the blood stains on it."
"As long as we don't alert him and make him alert again, he won't handle this crutch again."
As long as they don't show off, Ruyue Fengshui will still keep the crutch in his hand.
This does not affect the preservation of evidence.
And at the same time.
"We also need to make secondary preparations."
"That is" Lin Xinyi's voice became even weirder: "Sent people to secretly monitor the movements of Ruyue Fengshui and Tokiwa Mio."
"I think Ruyue Fengshui is likely to continue committing crimes."
"That Chairman Tokiwa might be his next target."
Lin Xinyi gave a "wait and wait" strategy.
If Ruyue Fengshui really committed another crime, the police would be able to catch him.
But the problem is
"Mr. Lin, how are you sure?"
"Will Ruyue Fengshui continue to commit crimes?"
"Besides, the target is Miss Tokiwa Mio?"
Officer Fang Gu's eyes were full of doubts.
"Uh" Lin Xinyi was embarrassed for a while:
Why does he know?
Of course it depends on Ke Xue.
Mio Tokiwa is a classmate of Kogoro Mori.
By some strange combination of circumstances, I was almost able to meet Conan face to face.
Now that Senator Oki and Jiaki Hara around Mio Tokiwa have been "killed", will she herself not be safe?
Based on this scientific reasoning, Lin Xinyi came up with the strategy of waiting for the rabbit.
Maybe this method is really useful, that is
"How do I explain this?"
Lin Xinyi was so confused that he felt guilty.
He hesitated and hesitated for a long time without making a sound.
finally.
"I see!"
Fang Gu Ling's eyes lit up.
He understood what Lin Xinyi meant:
"Mr. Lin, have you deduced Ruyue Fengshui's motive for murder?"
"." Lin Xinyi was slightly startled: "Huh?"
Just listen to Officer Fang Gu continue to say:
"Ruyue Fengshui first killed Representative Omu, and then left the same painted bowl as a symbol at the death scene of Yuan Jiaming."
"This means that Representative Ogi and Hara Jiaming are both on his killing list - even though Yuan Jiaming may not have been killed by him."
"Ruyue Fengshui wanted to kill these two people from the beginning."
"In serial murder cases, there are often some similarities between the victims."
"Assembly Ogi and Yoshiaki Hara, one is a Nishitama City Councilor and the other is a senior executive of Joban Group."
"The only connection between the two of them is..."
“Twin Towers Skyscraper!”
Representative Oki and Hara Jiaming were originally two people with completely different personalities, different origins, and completely unrelated lives.
It was because the Joban Group wanted to build a twin-tower skyscraper in Nishitama City and needed to have a relationship with Representative Oki. As a company executive, Hara Jiaki got to know him.
The person who introduced them was naturally the chairman of the Joban Group, Ms. Mio Joban.
"Although I still haven't figured out the murderer's motive."
"But the only connection between the two victims was the Twin Towers skyscraper."
"And this twin-tower skyscraper was built by Miss Tokiwa Mio."
"If Congressman Omu and Yuan Jiaming are really on the death list of Ruyue Fengshui because of their relationship with that building."
"Then Miss Tokiwa Mio is undoubtedly his next target!"
Fangtani Rei made some methodical reasoning.
It actually helped Lin Xinyi's metaphysical crime-solving method to provide a complete set of theoretical basis.
"Mr. Lin"
Officer Fangtani did not forget to praise him:
"I didn't expect that you are not only good at discovering and analyzing traces."
"His attainments in reasoning are not low at all."
"From the connection between the two victims, we can work backwards to deduce the murderer's motive, and then focus on the next victim who is most likely to be targeted by the murderer - this idea is indeed well-founded!"
"Uh haha"
Lin Xinyi smiled awkwardly:
"That's right. That's what I thought."
