"But..."
Someone in the crowd raised a question:
"We've had car fires before, but there weren't any explosions, right?"
"Normally, there will be fusible parts near the refueling port or other locations of the metal fuel tank, which will melt when exposed to high temperatures. At this time, the gasoline inside the tank will leak out, and there will be no explosion, only combustion..."
Sakaki Makoto looked over and saw that several traffic police officers were talking.
They deal 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 Makoto nodded slightly:
"You just said it was normal."
"The vehicle that Kiichiro Numabuchi was riding in had been tampered with by the murderer in advance, causing a small amount of oil leakage..."
"Oil leaks occur because there are holes in the tank that allow air to get in."
He took a puff of his cigarette, paused for a moment, and continued to explain:
"Gasoline doesn't explode, it just burns."
"What really caused the explosion was the oil gas produced when the volatile gasoline came into contact with the air."
"Oil and gas are very unstable. If they encounter open flames or sparks, they can easily burn and explode!"
At this point, he led everyone to the Nissan, whose fire had been put out, and pointed at the shattered car frame and said:
"You can check the vehicle."
"If I'm not mistaken..."
"We should be able to find some clues."
Flames will purify everything, but they cannot melt copper wire or metal fuel tanks instantly.
The charred body was put into a body bag and sent to the hospital for an autopsy...
The criminals from the Forensic Investigation Division of the Osaka Prefectural Police Headquarters put on gloves and began to examine the scene for traces.
this...
It is the first step to catch the murderer.
How can we convict a murderer if we don’t even know how he committed the crime?
After a few minutes...
The forensic team that was searching for evidence in the ruins soon came back with a few iron plates:
"Mr. Sakaki Makoto!"
"We found the pieces of the fuel tank, and sure enough, we found holes in it!"
Everyone looked...
The hole is located in the upper middle part of the fuel tank. Although it is covered with black impurities left after the burning gasoline, it can still be seen clearly.
"Um."
Wearing white gloves, Sakaki Makoto wiped off the black mud near the hole and said to the small round hole:
"As expected..."
"Mr. Sakaki already knows the methods used by the criminal?"
Conan's eyes lit up.
"I was involved in a similar case in my early years, and the criminal used the same method."
Nodding, Sakaki Makoto said:
“The holes drilled in the fuel tank are to allow air to enter the tank.”
"During driving, the temperature and pressure of the fuel tank are very high, and the gasoline will evaporate faster, producing a large amount of explosive oil and gas."
"As long as Kiichiro Numabuchi steps on the accelerator, the battery will start to work, the high voltage current will be connected, sparks will be generated, the cotton ball will ignite, and the cotton ball will then detonate the oil and gas..."
"boom!"
The five fingertips gathered together and then suddenly stretched out, and everyone's heart trembled when they heard it.
So far...
Everyone understood.
The method used by the criminal is not very difficult, but it requires a lot of knowledge about cars.
The hole drilled in the upper middle part of the fuel tank allows air to rush in and produce a large amount of oil and gas when enough gasoline leaks out during driving.
At this time, as long as Kiichiro Numabuchi stepped on the accelerator hard to stimulate the battery current...
"How could the murderer calculate so accurately?"
Hattori Heiji asked with a sullen face:
"I don't believe this is a coincidence!"
"It's certainly not a coincidence."
With a cigarette in his mouth, Sakaki Makoto picked up a piece of rubber paint from the ground, his eyes extremely cold:
"Everything was calculated by the murderer."
"Calculated?!"
Conan was shocked:
"How did you do that?"
"The murderer planned to have Kiichiro Numabuchi's car explode during a police chase, and take the opportunity to escape the crime."
Sakaki Makoto also didn't believe that the murderer had intended to let the car explosion affect the police from the beginning...
That's too metaphysical.
But the murderer is fully capable of controlling when the car explodes.
"Look at this tire paint..."
Sakaki Makoto placed the patent leather in his palm and held it out in front of everyone.
Everyone looked over and saw...
The patent leather is covered with cracks.
"What happened to the patent leather?"
"Before Kiichiro Numabuchi got on the bus, he must have been in a hurry and couldn't have had the time to check the condition of the bus."
Sakaki Makoto said:
"The maximum tire pressure a tire can withstand is 350-420kpa. If the murderer raised the rear tire pressure to 350kpa, the tire would be on the verge of its limit, and the fuel tank would explode at this time..."
"There is no doubt that the tire will not be able to withstand the pressure and will fall apart in an instant."
"Because the engine and transmission are near the front of the car, most cars are front-heavy and rear-light, especially Japanese cars from the 1990s, which are known for being light and fuel-efficient."
"After the tire exploded, the powerful shock wave reacted with the ground and flipped the car over. In the case of a fuel tank explosion, the car turned upside down and the burning gasoline instantly poured into the cab, ensuring the driver's death."
grass!
Everyone looked at each other and shuddered.
How cruel is this!
Even if the car explodes...
