"But."

Someone in the crowd asked:

"We have encountered car fire cases before, but there was no explosion?"

"According to normal circumstances, there will be fusible parts near the fuel port or other locations of the metal fuel tank, which will melt when encountering high temperatures. At this time, the gasoline inside the fuel tank will leak out, and there will be no explosion. It will only burn. right"

Sakaki looked and saw that several police officers from the Ministry of Transportation were talking.

They have been dealing with cars all year round and naturally understand the safety of car structures.

It is very difficult to make a car explode, but

It's not impossible.

"That's right."

Sakaki nodded lightly:

"You just said it was normal."

"The vehicle Kiichiro Numabuchi was riding in was tampered with in advance by the murderer, causing a small amount of oil leakage."

"If an oil leak occurs, it means there are holes in the tank where air can get in."

He took a puff of cigarette, paused briefly, and continued to explain:

"Gasoline doesn't explode, it just burns."

"What really causes the explosion is the oil vapor produced when volatile gasoline comes into contact with the air."

"Oil and gas are very unstable. When exposed to open flames or sparks, they can easily burn or explode!"

Having said this, he led everyone to the Nissan that had put out the fire, pointed to the tattered car body and said:

"You can check the vehicle."

"If I'm not wrong."

"You should be able to find clues."

The flame will purify everything, but it cannot instantly melt copper wires and metal fuel tanks.

The body, which looked like charcoal, was put into a body bag and sent to the hospital for autopsy.

Criminals from the Forensic Section of the Osaka Prefectural Police Headquarters put on gloves and began to examine the scene for traces.

this.

It's the first step to catching the murderer.

If you don't even know the murderer's modus operandi, how can you convict him?

A few minutes passed.

The forensics class searching for evidence in the ruins quickly came back holding a few iron plates:

"Mr. Sakaki Makoto!"

"We found pieces of the fuel tank, and sure enough we found holes in it!"

Everyone looks at

The hole is located in the upper middle of the fuel tank. Although it is covered with black impurities left after burning gasoline, it can still be seen clearly.

"Um."

Wearing white gloves, Sakaki wiped off the black mud near the hole and said to the round hole:

"As expected."

"Mr. Sakaki Makoto already knows the tactics used by the prisoner?"

Conan's eyes lit up.

"I was exposed to a similar case in my early years, and the prisoner used the same method."

Nodding, Sakaki said:

“The purpose of drilling holes in the tank is to allow air to enter the tank.”

"During driving, the temperature and pressure of the fuel tank are very high. At this time, the gasoline will evaporate at an accelerated rate, producing a large amount of explosive oil vapor."

"As long as Kiichiro Numabuchi slams on the accelerator, the battery will work, high-voltage current will be connected, sparks will be generated, igniting the cotton ball, which will then ignite the oil and gas."

"boom!"

The tips of the five fingers gathered together and suddenly relaxed, and everyone's hearts trembled when they heard it.

So far

Everyone understood.

The technique used by the prisoner is not very difficult, but it requires a lot of knowledge about cars.

The hole drilled in the upper middle of the fuel tank allows the Nissan to leak enough gasoline while driving, allowing air to flow in and produce a large amount of oil and gas.

At this time, as long as Numabuchi Kiichiro depresses the accelerator, the battery current will be stimulated.

"How could the murderer calculate so accurately?"

Hattori Heiji asked calmly:

"I don't believe this is a coincidence!"

"Of course it's not a coincidence."

Holding a cigarette in his mouth, Sakaki picked up a piece of rubber patent leather on the ground, his eyes extremely cold:

"Everything was planned by the murderer."

"Calculated?!"

Conan was shocked:

"How?"

"The murderer's plan was to have Numabuchi Kiichiro's car explode during the police car chase and take the opportunity to get away with it."

Sakaki Cheng also didn't believe that the murderer planned from the beginning to let the car explosion affect the police.

That's too metaphysical.

But the murderer was fully capable of controlling when the car would explode.

"Look at this piece of tire paint"

Sakaki Cheng put the patent leather in his palm and stretched it out in front of everyone.

When everyone looked around, they saw.

The patent leather was riddled with cracks.

"What happened to the patent leather?"

"Before Kiichiro Numabuchi got into the car, he must have been in a hurry and could not have had time to check the condition of the car."

Sakaki Cheng said:

"The maximum tire pressure that the tire can withstand is 350-420kpa. If the murderer increases the rear tire pressure to 350kpa, bringing the tire to the limit, then the fuel tank will explode again."

"There is no doubt that the tire will not be able to withstand the pressure and will collapse in an instant."

"Because the engine and transmission are near the front of the car, most cars are heavy at the front and light at the rear, especially Japanese cars from the 1990s, which are famous for being light and fuel-efficient."

"After the tire explodes, a powerful shock wave reacts with the ground and overturns the car. When the fuel tank explodes, the car overturns and burning gasoline will instantly pour into the cab, ensuring the driver's death."

grass!

Everyone looked at each other and shuddered.

How cruel this must be!

Just let the car explode.

Do you need double insurance?

Kiichiro Numabuchi probably dug your ancestral grave!

Crushing bones and ashes?

What a snake-hearted person

"Not only that, the murderer also designed a time difference."

Pushing up his sunglasses, Sakaki sneered:

"The alarm was raised every thirty minutes just to wait for the gas tank to be filled with air."

"Numabuchi Kiichiro doesn't want his whereabouts to be exposed. He will definitely abide by traffic laws and drive carefully. In this way."

"The copper wire cotton ball located above the oil surface will naturally not be stained by gasoline."

"When the gasoline is almost gone and the police find the vehicle in which Kiichiro Numabuchi is riding, then Kiichiro Numabuchi will run away in a panic and step on the accelerator!"

"High-pressure tires will reduce friction and grip, and the body will vibrate greatly, the fuel tank will shake, and the cotton balls will be covered with gasoline."

Every detail is planned.

The murderer not only calculated the time for the police to dispatch the police, but also calculated that Numabuchi Kiichiro would resist arrest.

Of course, this is not difficult.

As a serial murderer, Numabuchi Kiichiro will be sentenced to death if caught.

There is no doubt about it.

No matter how hard it is, he will die, will the other party just surrender?

The answer is no.

He will definitely fight to the death.

"Damn it!!!"

Hattori Heiji roared angrily, turned around and rushed towards the police car:

"Otaki Police Department!"

"Let's go find Sotaro Goji!!!"

"yes!"

Otaki Goro immediately followed.

Followed closely.

There are also a group of police officers from Osaka Prefecture.

They were really angry.

"Mr. Sakaki Makoto."

Nakamori Ginzo (Kidd) stepped forward and asked:

"Are we going?"

"What do you think?"

Sakaki said calmly:

"Go and get Ma Yuan's mother's fortune."

"Why"

Kidd ran back to the car and came back with two boxes of Dafu.

Sakaki Makoto

He took the Dafu and placed it in front of the Nissan.

Then he turned around and strode towards the police car.

Kidd happened to catch a glimpse of his profile and his eyes widened immediately.

Sakaki's eyes.

As cold as a cold knife.
