Chapter 479 Takagi's 300 Questions (Please Vote and Subscribe!!!)

Sakaki's words left Megure Thirteen and others completely confused.

In their understanding, it is normal for people who die in fires to have soot in their mouths and respiratory tracts.

but.

There was only a very small amount of carbon ash in Ota Kunimatsu's mouth.

Doesn’t this just prove that Ota Kunimatsu had been killed before the fire?

Could it be

What else is hidden in it?

"Brother Sakaki, please stop being so secretive!"

Mumu Shisan said:

“Why is Ota Kunisong the source of fire?”

"It's simple, shock!"

Pushing up his sunglasses, Sakaki looked at the ceiling and said:

"In a fire scene, high-temperature flames or hot airflow will act on the sensory nerve endings of the skin, causing severe pain and causing primary shock through nerve reflexes!"

"Just like on the battlefield, a soldier who is hit by a petrol bomb will first howl in pain, run around, and finally fall to the ground suddenly."

"When the soldier first fell to the ground, he was not dead yet and his life activities were still there, but..."

Pursing his lips, he added:

"This is a very painful and long process."

Primary traumatic shock, also known as acute traumatic neurogenic vascular failure, refers to the strong mechanical stimulation of peripheral afferent nerves on the body surface or internal organs, causing abnormal sympathetic or parasympathetic nerve reflexes, leading to microcirculation disorders in important organs of life, die.

In layman's terms

When areas rich in nerve endings such as the carotid sinus, upper abdomen, spermatic cord, and vulva receive a fatal blow, it may cause a sudden drop in blood pressure, syncope, bradycardia, or even cardiac arrest.

Dying from pain is a real way of dying.

so.

When boys go out, they must protect their important parts and be careful of the impact of broken eggs.

Everyone looked at each other, still not understanding what the shock had to do with Tinder.

"Hmm"

Conan, who was bowing his head in thought, said at this time:

"Mr. Sakaki, do you mean that Ota Kunimatsu was burned alive?"

"Did he accidentally cause this fire during his struggle?"

"That's right!"

Nodding heavily, Sakaki said:

"This is also the reason why Ota Kunimatsu was obviously burned to death, but there was no accumulation of carbon ash in his mouth, nose, throat and stomach!"

If so inferred

The reason for the severe carbonization of the body was also found.

"Is it possible that Ota Kunimatsu was killed first and then set on fire to destroy the body and eliminate all traces?"

Takagi Wataru, who had been taking notes, raised his hand and asked:

"In this way, there won't be too much carbon ash accumulated in the mouth of the corpse."

"Blood stains."

Glancing at him, Sakaki replied:

"People are fragile but also very strong."

"There are only a few ways to kill a grown man."

"Flame can wipe out most of the clues and evidence, but it cannot completely eliminate the blood residue at the scene."

At this point, he paused briefly and pointed to the corpse's cut stomach:

"Of course, we cannot rule out the possibility that Ota Kunimatsu was poisoned, so..."

"I'm just going to cut open his stomach and do a preliminary drug test."

"Where's the cyanide?"

As a good student, Takagi Wataru successfully came up with a hundred thousand whys:

"If Ota Kunimatsu was poisoned with cyanide first and the prisoner set fire to it, there would be no traces left."

The corner of his mouth twitched slightly, Sakaki was really confused by the question.

He was finally convinced.

Takagi is involved in one problem after another, and everything is tricky and difficult to solve.

Now the method of death is linked to cyanide

Without professional equipment on hand, it is difficult to check whether there are cyanide residues in the body.

but.

"The probability of inmates using cyanide is low."

Miss Miyano, who was watching coldly, came over and answered Sakaki's doubts:

"Ultimately, the way cyanide causes death is by paralyzing the human body's respiratory muscles, causing the central nervous system to lose function and organ failure."

"And the corpses poisoned by cyanide all have one characteristic in common!"

As soon as his eyes lit up, Sakaki knew what she wanted to say.

yes!

Why didn't I think of such a simple point?

Just like Nao Kamikawa who was almost poisoned by cyanide, if Ota Kunimatsu was also poisoned by cyanide, his mouth should be completely open.

There are two ways people breathe:

Inhale through nose and mouth.

Breathing is an essential part of maintaining life. When a certain channel is blocked, people will inevitably use another breathing method to absorb oxygen.

For example, telangiectasia caused by rhinitis causes tight cavities and poor breathing.

Sakaki once conducted an experiment:

He pinched the nose of his sleeping partner and found that after a brief period of stillness, the other person's breathing pattern changed from the nose to the mouth, and at the same time.

Wake up.

This phenomenon shows that the two breathing methods of the human body can be freely switched. It is a muscle reflex and can be performed even without consciousness.

so.

People who are poisoned by cyanide will definitely open their mouths and try to breathe.

But Ota Kunimatsu's body did not have such movements, and his mouth was opened by Sakaki Makoto himself.

"I see."

Takagi Wataru nodded, wrote down what Miss Miyano said, and asked again:

"Is it possible that it was suicide?"

Sakaki Makoto: "."

For some reason, he suddenly wanted to give Takagi Wataru a stick.

Day by day.

Why are there so many problems?

It's a good thing to ask for advice humbly, but asking too many questions at once can easily arouse others' resentment.

Such as now

"With a happy family, good health, no bad habits, and no mental illness, why did Ota Kunimatsu commit suicide?"

Sakaki glared at him angrily:

"Even if he wants to commit suicide, does he have a grudge against himself by burning himself to death in such a cruel way?"

"Well"

Suddenly, his words choked, and Takagi Sheba was speechless.

To solve a case, pay attention to evidence and commit the crime.

You need motivation.

There must be a reason why Ota Kunimatsu was burned alive in the gymnasium.

"Memu Police Department, please investigate the suspects who had no alibi in the school at the time of the incident."

Because the school gate was blocked in advance, it was impossible for the suspect to escape in the chaos.

This also provides Sakaki with the possibility of quickly solving the case.

After hearing his words, Mumu Shisan immediately sent his men to investigate the classrooms without saying a word.

ten minutes later

"Brother Sakaki Cheng, after police investigation, it was found that most of the teachers were in class at the time of the incident, but they had no alibi."

Mumu Shisan led the three people forward.

Sakaki looked intently and saw.

They were two men and one woman. The first was a middle-aged man wearing plastic clothes and muddy boots. He looked like a gardener.

The second person is a school janitor with a dark face and weather-beaten appearance.

The third person is a young girl with pretty appearance and looks about twenty years old.

"Gardener Toshio Samejima, cleaner Koizumi Ryuji, and college student Risa Goto"

Miwako Sato recited her name and the introduction was completed:

"That's the three of them."
