Coroner Coroner

That was the photo of the suspect Ru Yuefengshui in the case file.

In the photo, the old painter Ru Yuefengshui is wearing a simple and simple bathrobe, with a slightly hunched body, holding...

Also leaning on a strong and slender wooden crutch.

"The second murder weapon used by the murderer is the crutch that he usually carries with him."

"No one would be suspicious of an old man on crutches."

"The murderer... is Ruyuefengshui!"

Chapter 437

The so-called "wooden stick-like weapon" is crutches.

Knowing this can explain a lot of things:

The murderer didn't deliberately bring a slender wooden stick that didn't go well, but he usually carried a cane with him.

Because of this, Senator Oki did not become suspicious when he saw the "weapon" carried by the murderer.

"Also, what if the murderer is a mysterious person who sneaked in from the outside world."

"If this mysterious person sneaked into the building unknowingly, I'm afraid he wouldn't bring such an inconvenient and ineffective weapon like a wooden stick."

"This further shows that the murderer is the inseparable Ruyuefengshui, not some mysterious person who sneaked in from the outside world."

After analyzing this point, the identity of the murderer can basically be determined.

Then...

"How to find evidence that he is the murderer?"

Unknowingly, Officer Jianggu still forgot the purpose of his visit this time.

He was no longer in a hurry to worry about whether the original Jiaming case was related to the organization, but he was quite concerned, thinking about ways to bring justice to the dead and punish the murderer:

"We have come to this conclusion, to a certain extent, by the profile of the perpetrator deduced from the traces at the scene."

"Just relying on these more inferential clues, I'm afraid it's not enough for Mr. Ruyue Fengshui to plead guilty."

Jiang Gu Ling talked about the biggest problem at present:

Ru Yuefeng Shui is indeed the number one suspect, but the police still lack evidence to convict him.

"This..." Hearing this question, Lin Xinyi also quietly frowned.

He didn't give a direct answer, but carefully looked at Ruyuefengshui in the photo, and the crutch in his hand.

The elderly are nostalgic for the old, and this crutch is very old at first glance.

The armrests looked like they were going to be polished and covered with pulp.

As for the bottom of the crutches, the parts that often come into contact with the ground, walls, and roadsides...

The wood paint covering it has also peeled off little by little, exposing the cracked wood inside.

"This crutch..."

"Is the Ruyuefeng water still in your hand?"

Lin Xinyi asked thoughtfully.

"It should still be in his hands."

"This file photo of crutches was taken by the police officer we sent to investigate and question, and it was taken by Ruyuefengshui at the scene."

Jiang Gu Ling gave an affirmative answer.

He also understood what Lin Xinyi meant by asking this question:

"Mr. Lin, do you want to find evidence of Ruyuefengshui's murder from this crutch?"

"But the problem is... since he dared to keep the crutch as one of the murder weapons in his hand after committing the crime, he should have already cleaned up the traces on it."

Two days have passed since the death of Senator Oki.

These 2 days are enough for Ruyuefeng water to clean up the murder weapon.

Unless he was a fool, he would not keep a crutch still stained with the blood of the dead in his hand.

"But we can try our luck."

Lin Xinyi pointed to the cane on the photo and said:

"see it?"

"The base of the cane has chipped paint and there are gaps in the exposed wood surface."

"And when the murderer used this crutch to hit the deceased on the head during the fight, most likely he would hold the top of the crutch with his hand and attack with the bottom part in the most convenient way."

"This means that the bottom of the crutch was in direct contact with the wound on the head of the deceased, and it must be stained with the blood of the deceased."

"The blood is likely to seep into the gaps in the wood and seep into the inside of the crutch."

"if so…"

Lin Xinyi paused slightly, and emphasized:

"Then the blood inside the wood cannot be cleaned by ordinary cleaning methods."

Ground cracks, brick cracks, knife handle gaps, wood gaps, these inconspicuous gaps in life have always been the focus of forensic medicine.

And those murderers thought they could clean up the physical evidence, but in fact they often only cleaned the surface.

like this crutch...

"If you just wipe the surface, you won't be able to contaminate the blood stains inside the wood."

"Unless he threw the whole crutch into a chemical reagent for a long time, the blood soaked into the wood would be basically impossible to clean."

"So, we can take our chances."

"Perhaps the blood of the deceased Councilor Oki can be tested from Ru Yuefengshui's crutches."

Lin Xinyi's voice was full of confidence.

He believed that the old man like the moon was not so smart, nor was he so cautious.

After all, if he was really cautious enough, he should have thrown away the bloody crutch long ago, or burned it clean.

But Ru Yuefeng Shui still kept the crutch in his hand.

This shows that he is really too "confident".

And once people are overconfident, they will neglect the details.

"Officer Jiangu, inform your colleagues."

"Let them control Ruyuefeng Shui as soon as possible, and then send his crutches to Kesouyan for blood test."

Lin Xinyi's tone was very firm.

But hearing his plan, Jiang Gu Ling hesitated:

"Isn't it a little reckless to go to Ruyuefengshui for a showdown now?"

"If the other party really cleaned up the murder weapon thoroughly, and no blood can be detected in the crutches, then..."

Then you can only spread your hands and let people go.

Moreover, the other party will definitely be vigilant about this after such a frightening operation, and will be a hundred times more cautious than before.

It is difficult to find a breakthrough from him again.

"Eh..." Lin Xinyi was also speechless.

He also understands the risks involved.

But now no one can think of another way, what else can we do if we don't try our luck like this?

At least, it seems that the police have a good chance of winning in this gamble.

It's okay to take a risk and gamble.

Lin Xinyi originally thought so in his heart.

But when police officer Jianggu said it so solemnly, he couldn't help becoming a little tangled:

"The way... other than luck, is there any other way?"

He bowed his head in thought for a while.

As he was thinking about it, his expression quietly became weird.

He does have a way.

Moreover, this method was thought of in a few seconds by him without any thought at first.

"Uh... so..."

Lin Xinyi hesitated several times, and finally said the words in a subtle tone:

"We're still on the sidelines."

"Anyway, Ru Yuefeng Shui has confidently left the crutch behind, so she must believe in herself, and has cleaned up the blood stains on it."

"As long as we don't startle the snake and make him vigilant again, he won't deal with this crutch again."

As long as they don't show their cards, Ru Yuefeng Shui will still keep the crutch in his hand.

This does not affect the preservation of evidence.

And at the same time…

“We also have to be prepared secondhand.”

"That's..." Lin Xinyi's voice was even weirder: "Send someone to secretly monitor Ruyue Fengshui and Tokiwa Mio's movements."

"I think that Ruyuefengshui will probably continue to commit crimes."

"That Chairman Chang Pan may be his next target."

Lin Xinyi gave a strategy of "waiting for the rabbit".
