Chapter 418 Poor secret room techniques

When Lin Xinyi followed Mao Lilan, who came to report the news, and hurried to Usui Ritsuko's room, the room was already surrounded by people.

There were hotel staff, Fei Yingli and several of her lawyer colleagues,

Hoshi Saku and Kogoro Mori were also here. They blocked the door of the crime scene tightly and spontaneously maintained order.

"Mr. Saku."

Lin Xin got straight to the point as soon as he came up:

"I heard from Miss Maori that you were the first one to enter the scene."

"Can you tell me the specific situation at that time?"

"Of course." Saku Hashi nodded in response:

"A few of our colleagues had made an appointment to go to Mount Asama together in the morning."

"But Miss Ui Bing didn't show up until everyone finished breakfast, and no one answered her phone."

"We felt strange, so we came to her room to look for her."

Fashi Saku paused for a moment, then quietly increased his tone:

"No one answered the door, and even if I called her loudly, there was no reply."

"We felt something was wrong, and the door to her room was still hung with an anti-theft chain, so it couldn't be opened from the outside."

"So, there is no way."

"Because I was worried that something would happen to Miss Ui Bing in the room, I was so desperate that I could only force the door open."

"But it's too late."

He staggered his body, allowing Lin Xinyi to see the body lying on his back on the big bed in the room:

"When I opened the door, Miss Ui Bing was already dead."

Lin Xinyi thought for a while.

He quickly grasped the key point of Saku Hashi's statement:

"Mr. Saku, are you saying that the door has an anti-theft chain from the inside and is always locked?"

The door was locked with an anti-theft chain and could not be entered from the outside, but the person inside was dead.

Isn't this a typical locked room murder?

Or is this a simple accident?

"No"

Mao Lilan shook his head cautiously:

"Mr. Lin, I think this was a secret room murder."

"Oh?" Lin Xinyi frowned quietly:

"Have you found evidence that this is homicide?"

"Yeah." Mao Lilan expressed his opinion hesitantly:

"When Mr. Saku and other lawyers knocked on the door, my mother, myself, and Conan happened to be passing by."

"So I entered the scene as soon as possible and did a rough inspection of Miss Ui Bing's body before I went to find Mr. Lin who came here."

Hearing this, Lin Xinyi felt relieved a little:

Since both Conan and Mao Lilan were present when the crime occurred, the crime scene should have been completely protected in a timely manner, and there was no possibility of it being sabotaged or manipulated secretly.

Lin Xinyi nodded with satisfaction and signaled Mao Lilan to continue.

Mao Lilan immediately turned his head and looked at the body lying on the bed in the room:

"I have seen the body of Ritsuko Usui."

"Her face was bruised and swollen, her ten nail beds were cyanotic, and she had extensive spotting of conjunctiva in both eyes."

These are typical characteristics of death by suffocation.

The direct cause of Ritsuko Usui's death was almost certainly suffocation.

So, what causes suffocation?

The most common killing methods in this criminal case are covering, strangling, strangulation, and suffocation.

"Much killing, strangulation, and strangulation, these three violent methods of suffocation, will leave extremely obvious traces of covering, strangulation, and strangulation marks on the deceased, such as subcutaneous bleeding and epidermal peeling."

"But there are no traces of these on Miss Ui Bing at all."

"Her face and neck were 'clean' with no visible damage."

"But. I opened her lips and found:"

"There was a small amount of blood in her mouth, and there was obvious damage to the oral mucosa."

There were no injuries on his face and neck, but there was damage to the oral mucosa.

This almost clearly reveals the cause of death of the deceased:

"Suffocate?"

Lin Xinyi came up with Mao Lilan's idea.

Using soft objects such as pillows and quilts to suffocate the victim's mouth and nose can suffocate the victim without leaving any obvious traces on the body surface.

If it were the former Metropolitan Police Department, seeing such a "clean" looking corpse, they would probably have happily closed the case "accidentally" and gone back to have a celebration banquet.

But now, this trick cannot fool the police officers who have been specially trained by Lin Xinyi:

Suffocating someone's mouth and nose with a pillow will not leave obvious scars on the body surface, but there is still a process of "downward pressure".

Although pillows are soft, human teeth are very hard.

Therefore, when the victim's head is held down and suffocated, the teeth will definitely squeeze violently against the oral mucosa, resulting in mucosal damage and oral bleeding.

"Miss Ui Bing had a small amount of bleeding from her mouth, and she died of suffocation."

"So I judge that she most likely died of suffocation caused by others, and she used secret room killing techniques."

"And her body was found on the bed, with a pillow next to it that could be used as a crime tool, which further proves my guess."

Mao Lilan concluded.

Lin Xinyi, who had nodded repeatedly before, now quietly stopped and pondered:

"Minor bleeding"

"You said the bleeding in her mouth was a 'small amount'. How much was it?"

"Uh" Mao Lilan was confused.

She didn't know how to answer this question specifically:

"There are very few details about the situation. It's up to you, Mr. Lin, to see for yourself!"

"Yeah." Lin Xinyi didn't ask any more questions.

He was not in a hurry to enter the room to survey the scene and examine the body, but stopped at the door.

He carefully observed the anti-theft chain that was broken by Saku Hashi.

This anti-theft chain was locked from the inside when the crime occurred. It was it that turned the scene into a so-called secret room.

"There's something wrong with this anti-theft chain."

'It's been tampered with. ’

Lin Xinyi barely hesitated for half a second and saw this clumsy secret room technique at a glance:

"This anti-theft chain was not broken by a collision,"

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

He even named the tool the murderer used to cut the anti-theft chain.

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

For example, a vise:

The clamp blade just contacts the object and continuously exerts pressure. Once the stress at the contact part of the object exceeds the elastic limit, plastic yield will occur and plastic deformation will occur, reflecting the characteristics of the clamp blade.

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

These marks were special enough to Lin Xin, allowing him to identify the tools used by the murderer at a glance:

"The murderer probably used a vise to cut off the anti-theft chain after the murder."

"Then."

Lin Xinyi gently leaned down, searched carefully, and soon found a short fishing line as thin as cow hair on the carpet near the door:

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

"In this way, the anti-theft link looks like it has not been broken yet."

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

"When others discovered the problem and broke in through the door, it looked like they had broken the anti-theft chain, but in fact, it was just this small fishing line that was broken."

In just a few words, he exposed the murderer's secret room murder plot.

At the same time, everyone's expressions looking at Saku Hashi suddenly became strange:

"Mr. Saku, you."

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

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

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

In this way, the person who invisibly "cooperated" with the murderer to break down the door looked very suspicious.

Say it politely.

There is a high possibility that he is the murderer.

"Hey, hey."

Faced with everyone’s doubts and vigilance, Saku Hoshi’s attitude was very calm:

"Don't look at me like that."

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

"." There was silence for a while.

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

In the end, it was Lin Xinyi and Sakubo Fashi who said:

"That's right."

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

“I’ll wait until I conduct a detailed on-site investigation to tell you everything.”

Lin Xinyi did not take advantage of the opportunity to question Saku Hoshi.

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

"Mr. Lin"

Mao Lilan followed up carefully and whispered in his ear again:

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

"Yeah." Lin Xin kept speaking his thoughts bluntly: "I don't think he looks like him."

"because."

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

As long as a person has a little training in systematic trace inspection, he can see the mystery behind it.

Hoshi Saku is a famous lawyer in Tokyo who specializes in criminal litigation. He is very familiar with the Metropolitan Police Department, the forensics department, Lin Shinichi, and even the dogs around Lin Shinichi.

Since Saku Hoshi knows the power of the forensics class and knows the three trump cards of the forensics class, they are all in this hotel at the moment.

Then he still dares to kill people in such a clumsy way?

Isn't this a show of force in front of Guan Gong, who comes to kill people?

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

So he didn't rush to question Saku Hoshi.

Instead, they were given priority to enter the scene and perform a postmortem examination on the deceased Ritsuko Usui.

This inspection took very little effort.

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

"Dander."

"The deceased had skin flakes in his fingernails!"

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

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

Then the skin flakes are almost certain to come from the murderer.

There was a high probability that the murderer was scratched by her in the struggle when she was killing Ritsuko Usui.

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

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

Lin Xinyi came to the conclusion in a relaxed tone.

"Scratch?"

Mouri Kogoro, who was waiting outside the room and consciously helped his daughter act as an investigation assistant, immediately became excited:

Secret room murders are 100% committed by acquaintances.

Therefore, the scope of the suspect is also easy to lock.

Even Mouri Kogoro, who specializes in catching rapes, could quickly think at this moment that the lawyer colleagues of Ritsuko Usui present were the most suspicious:

"quick--"

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

Keep the change, please.

A voice sounded coldly.

Fei Yingli stood up with a gloomy face:

"That person is me."

The second is later
