"Hmm"

Pulling open the heavy solid board, a puff of smoke rose up.

Fanning his palms to scatter the smoke, Sakaki looked intently.

The clothes were completely burned, the body was curled up into a ball, the arms were raised high, the internal organs were exposed, and the area below the knees was completely shattered. It was black as if a layer of ink had been splashed on it. The surface skin was burned away, and even the muscle tissue underneath was carbonized.

The only thing that was still intact was the exposed and dazzling white ribs.

“It’s so miserable”

Hattori Heiji whispered:

"Even if you are in a fire, it shouldn't be burned so completely. It's just like, like"

"It's like being cremated."

Conan continued the second half of his sentence.

Burning to death is definitely one of the most painful ways to die.

Snap!

Putting on his gloves, Sakaki knelt down and stretched out his palms

The almost completely carbonized body couldn't even withstand his gentle touch and broke into pieces instantly.

"It's troublesome."

Sakaki frowned.

The body was burned to such an extent that it was very difficult to find any clues from it.

Fortunately

Because the body was curled up and the internal organs were protected by the ribs, the damage was not serious.

This is also one of the few ways to get clues.

What a blessing in misfortune.

"Don't do anything"

Sakaki Cheng stopped Miss Miyano who wanted to conduct an autopsy:

"I'll do it."

His eyes were extremely serious. Miss Miyano hesitated but did not intervene.

As much as possible, Sakaki Makoto did not want Miss Miyano to come into contact with the corpse of such a painful death.

It would be better to stop and watch, if an autopsy is performed.

It is bound to cause serious psychological burden to Miss Miyano.

some pressure

He could just bear it alone.

Letting the corpse face up, Sakaki carefully opened the corpse's eyelids.

The lens is severe, or

It had dried to a sticky mass.

Sakaki's face became more solemn.

He turned to examine the head and crotch of the body, and measured the length.

"The body is 95cm long, male."

After opening Sa Sa's mouth, which was dripping with powder, Conan turned on the flashlight and illuminated the mouth of the corpse for Sakaki Cheng.

"There are smoke stains on the teeth, a little carbon ash on the lips, tongue and throat, and there are burn marks."

Without professional tools, Sakaki couldn't tell the age of the other person from the corpse's teeth.

but.

He picked up the key that had fallen next to the body and looked at it in the light.

"This is."

The old principal who was watching his every move from behind suddenly said:

"The key to the gymnasium warehouse!"

"Um"

With a serious face, Sakaki said word by word:

"Teacher Uematsu, are there any adults missing from the school?"

The old principal reacted immediately and said to the secretary standing aside:

"Go and find out who is missing in our school."

"yes."

The secretary hurriedly walked out of the warehouse, found two helpers, and checked each classroom one by one.

About 15 minutes later.

Da da da.

"headmaster!"

Wearing high heels, the secretary ran back:

"Teacher Ohta from the health room is missing!"

"Can he get through on the phone?"

"I tried it, but it doesn't work!"

"This Mr. Ota you are talking about, is he using a Samsung flip phone?"

The old principal and secretary looked down

Conan walked over with a phone in his hand with the battery exploded, the screen shattered, and only an empty shell left:

"I just found this from the ruins."

I saw the Samsung logo on the empty shell.

The old principal closed his eyes and nodded sadly:

"I didn't expect that Ota Kunimatsu-sensei would be so excited!"

With a flash of his eyes, Sakaki noticed something was wrong.

Health room teacher

Why did he come to the stadium alone with the key to the sports warehouse?

Why didn't he escape when the fire broke out?

What was the cause of the fire?

Hattori Heiji had the same question as him. While waiting for his secretary to come back, he specifically went to ask the fire brigade and learned that

"The fire was probably caused by sparks igniting the mats in the sports warehouse."

Burning corpses to eliminate traces is not groundless.

Among the countless cases Sakaki has encountered, the fire scene is definitely the most difficult to investigate, bar none.

When a fire occurs, it only takes 10-15 minutes for the fire temperature to rise to 400°C. If people in the fire area cannot evacuate in time at this time, they will be poisoned by smoke, suffocated, and even scalded or burned alive.

This is just the temperature when the fire started.

If there are ordinary organic matter in the fire scene, such as cloth, wooden boards, etc.

Taking a closed gymnasium as an example, the flame, hot air layer and walls will quickly accumulate heat, and finally return the heat to the combustibles in the form of convection and radiation, thus intensifying the gasification (thermal decomposition) and combustion of the combustibles.

Especially radiant heat, strong radiation will pose a great threat to nearby buildings. When the radiant heat reaches a certain level, combustible materials far away from the fire object will also be ignited, and the fire will further intensify. This interaction will also called

Flashover.

Once the flashover mode is entered, the temperature at the fire site will soar from 400-500℃ to 800-900℃, and the local temperature can even be as high as 1100℃, which is related to the type of combustibles at the fire site.

The gymnasium covered with wood is simply the best lover of flames.

The wall has been battered but still strong, which shows that Didan Primary School did not cut corners in the construction of the gymnasium.

What puzzled Sakaki.

Why did health teacher Kunimatsu Ota accidentally cause a fire?

Could it be that when he was smoking, the cigarette butt accidentally dropped on the mat?

But this doesn’t make sense

No matter how fast the fire spreads, Ota Kunimatsu, who has the key, can escape calmly without being burned alive.

All signs indicate that this fire is not as simple as it seems.

The piercing sirens sounded from far to near, and sounded in the distance.

After a long wait, Memu Shisan and a man with a crew cut who looked a little unfamiliar finally arrived with their men.

"Brother Sakaki Makoto?!"

Megure Thirteen, who entered the gymnasium with Takagi Wataru and Sato Miwako, immediately saw Sakaki Makoto surrounded by the crowd:

"Why are you here?"

"I went back to school to visit my teacher and accidentally ran into a case. Who is this?"

"He is the police chief of the Investigation Section 1, specializing in arson cases."

Memu Shisan introduced the flat-headed man next to him:

"This time, because the body was found, we also came with the three forces."

"Hello."

After a brief answer, Sakaki Cheng asked directly without any intention of small talk:

"Megure Police Department, can I perform an autopsy on the body?"

"Ah, sure."

Megure Thirteen, who has not yet figured out the situation, shows his 100% trust in Sakaki.

At the same time, he was also keenly aware of it.

This case is likely to be a murder.

Otherwise, why would Brother Sakaki do an autopsy?

There must have been something fishy!

After receiving an agreed answer, Sakaki asked the firefighters for a knife, but they didn't have an ordinary knife, so they took it off.

An ax hanging from his waist.

Depend on.

Sakaki weighed the fire axe, somewhat dumbfounded.

This was the first time in his life that he used an ax to perform an autopsy.

It can be considered the only one in eternity.

After comparing it with the corpse's stomach, Sakaki raised his axe.
