Coroner Coroner

"This anti-theft chain is not broken,"

"It was cut off with a vise before it was hit."

He even spoke out the tool used by the murderer to cut the anti-theft chain.

Because several common cutting tools, such as pliers, scissors, bolt cutters, etc., have different shapes and different ways of exerting force, the traces formed are also completely different.

For example, a vise:

When the pincer blade just touches the object and the pressure is continuously applied, once the stress on the contact part of the object exceeds the elastic limit, plastic yield will occur and plastic deformation will occur, reflecting the characteristics of the pincer blade.

When the blade moves inside the object, the hardness of the blade is generally greater than that of the object, and line marks will appear on the object.

These traces are special enough for Lin Xin to allow him to identify the tools used by the murderer at a glance:

"The murderer should have cut off the anti-theft chain with a vise after the murder."

"Then…"

Lin Xinyi bent down slightly, searched carefully, and soon found a short fishing line as thin as a cow's hair on the carpet near the door:

"Then he walked out of the room and used this short fishing line to fasten the broken anti-theft chain again."

"In this way, the anti-theft chain looks like it hasn't been broken."

"This room has become the so-called 'secret room'."

"Wait for someone to find out the problem and break into the door... It looks like the anti-theft chain has been broken, but in fact, it's just this little fishing line that was broken."

In a few words, he exposed the murderer's conspiracy in the secret room.

At the same time, the expression of everyone looking at Hoshi Saku suddenly became weird:

"Mr. Saku, you..."

At that time, it was Saku Hoshi who broke the anti-theft chain under the pretext of "hurrying in to check the situation".

And this anti-theft chain is a trick set by the murderer.

Just wait for someone to come and slam the door violently, "breaking" the anti-theft chain that had been cut long ago, and completely complete this secret room technique.

In this way, the person who invisibly "cooperated" with the murderer's knock on the door looked very suspicious.

bluntly speaking...

There's a good chance he's the murderer.

"Hello..."

In the face of everyone's doubts and vigilance, Hoshi Saku's attitude was very calm:

"Don't look at me like that."

"I just chose to knock on the door out of desperation. Just this, can't prove that I am the murderer?"

"..." A moment of silence.

In the silence, the suspicion in everyone's eyes has not been alleviated in the slightest.

In the end, it was Lin Xin and Saku Hoshi who said:

"Yes."

"It's too early to say who the murderer is."

"Everything will be discussed after I have done a detailed site survey."

Lin Xinyi didn't take advantage of the situation to interrogate Saku Hoshi.

Instead, he put on a mask, hair cover, and gloves on his own, and slowly walked into the scene with the forensic investigation box he carried with him.

"Mr. Lin..."

Mao Lilan followed up cautiously, and whispered in his ear:

"Do you think Mr. Saku Hoshi is not the murderer?"

"Hmm." Lin Xin has been bluntly expressing his thoughts: "I don't think he looks like him."

"because…"

Because the level of this secret room technique is too low.

Those who have undergone a little trace inspection training will be able to see the mystery behind this.

Hoshi Saku, on the other hand, is a famous lawyer in Tokyo who specializes in criminal proceedings. He is very familiar with the Metropolitan Police Department, the forensics department, Lin Xinyi, and even the dog beside Lin Xinyi.

Since Saku Hoshi knew the strength of the forensic class and the three trump cards of the forensic class, they were all in this hotel at the moment.

Then he dared to use such a clumsy method to kill people?

Isn't this just playing big swords in front of Guan Gong and sending people's heads at the door?

Therefore, Lin Xin subconsciously felt that this lawyer Saku did not look like a murderer.

So he was not in a hurry to question Saku Hoshi.

Instead, he entered the scene first and checked the body form of the deceased Ritsuko Usui.

And this inspection took almost no effort...

Lin Xinyi immediately made a major discovery that could influence the case:

"Dandruff..."

"The dead man had dandruff in his fingernails!"

Both Lin Xinyi and Mao Lilan breathed a sigh of relief:

If leather shoes are found in the fingernails of the deceased, and the deceased himself does not have any scratch marks that can be formed independently.

Then the dander is almost certainly from the murderer.

There is a high probability that the murderer was scratched by Ubing Ritsuko while she was struggling.

"Now, we have to give priority to finding the person with the scratch marks on his body."

"Compared to Mr. Saku Hoshi, that person is the biggest suspect in this case."

Lin Xinyi came to a conclusion with ease.

"Scratched?"

Kogoro Mori, who was waiting outside the room and volunteered to help his daughter as an investigation assistant, immediately became excited:

Murder in a secret room is 100% committed by an acquaintance.

So the range of suspects is also well locked.

Even Kogoro Mori, who specializes in catching rapes, can quickly think that the lawyer colleagues of Ritsuko Ubing present are the most suspicious:

"quick--"

"You all take off your coats and see who gets scratches!"

"keep the change."

A voice sounded coldly.

Fei Yingli stood up with a gloomy face:

"That person is me."

Chapter 414 The Suspect Concubine Yingri

Under the suspicious eyes of everyone, Fei Yingli lifted up her cuffs slightly.

I saw three shocking scratches on her originally clean and flawless arm.

"It was scratched by Ritsuko Ubing."

Fei Yingli said without hesitation:

"If there's flakes in her nails, it's probably mine."

"Ying, Yingli?" Kogoro's smile froze on his face.

He never expected that the number one suspect he was looking for was actually his wife.

"why?!"

Mori Kogoro asked in disbelief:

"Eri, aren't you and Usui-san friends?"

"Why are you fighting?"

"Friend?" Fei Yingli frowned: "Do you still know that she is my friend?"

"Then you were in front of me yesterday, with her..."

She subconsciously wanted to express the resentment that had been suppressed in her heart for a long time, but her face turned red, and she hesitated to speak.

"Eri..." Mori Kogoro realized belatedly: "You are..."

"Don't be sentimental."

Fei Yingli lowered her head and pushed the glasses on the bridge of her nose, as if she didn't pay attention to this man at all.

She still maintains that duplicity and aloofness:

"I don't care what kind of woman you want to mess with."

"What I care about is why Usui Ritsuko did this to me."

"What is she contradicting me?"

"So, after the banquet last night, I went to Usui's room to have a showdown with her, and then chatted with her for a while."

The negotiations obviously did not end in a peaceful way.

Fei Yingli doesn't need to go into details, everyone can imagine the fierce scene of a pair of "plastic sisters" turning from literary fighting to martial fighting after their faces were completely torn apart last night.

"At the end of the chat, Ubing was too emotional."
