Detective: I have a split personality, but I'm not a murderer

Inside the lab!

Hearing that the second discovery of the High Court was red mud, everyone was stunned.

Even Xiong Leilei found out that it was not right:

“Brother, red mud can’t be considered a discovery, can it?!

Do you know that the previous red mud leakage accident caused a lot of red mud in the lake, and caused pollution and corrosive environment of the lake?

Isn’t it normal for that car to soak in the lake for so many years and find red mud on the tires of the car?

How can this serve as a clue? ”

“That’s right!”

He Fudao also wondered

“You should have read our previous appraisal report.

We also found red mud in places like car tires and even roofs.

But this is not a clue at all! ”

Hearing the doubts of the two, Gao Ting said with a smile

“If the red mud is found on the surface of the car body and tires, it naturally cannot be used as a clue.

But the red mud I found was inside the tire rubber! ”

“Huh?”

“Inside the rubber?”

“What do you mean?”

“How did the red mud get into the rubber?”

“High Court, you quickly explain and explain!”

……

“It’s actually very simple!”

Gao Ting said: “This involves the specific process of throwing the car by the kidnappers.

After the kidnappers were successfully kidnapped, they should have driven Cadillac to the hiding place found in advance.

Because they want to immediately call the Zhou family for blackmail, so as to avoid the Zhou family finding no one to call the police directly.

Only then did they have time to dispose of the bodies of the three dead and arrange for the sinking of the car.

They must have driven the Cadillac to the lake, poured gasoline on the car, and then sank the car. ”

“It should be the process!”

Lin Xiaoxiao asked while recording in the small book

“But does this have any effect on the identification of physical evidence, as well as the red mud you found?”

“Of course there is!”

Gao Ting said with a smile

“Everyone knows that in order to increase friction, the tires of cars are patterned.

And these concave patterns are easy to squeeze into fine gravel and other substances. ”

“But we thought of this too!”

A technician said:

“Wheel gaps are a key focus in the assurance process.

In many cases, the murderers were caught because of the clues left in the gap between the wheels, revealing that they had been to the place of the crime.

But in this case, we all looked for the gap in the wheel.

But only ordinary sediment and other substances were found.

And there are very few of them! ”

Gao Ting nodded again:

“I found out that too!

Given that very little substance is found on the wheels, there should be an operation to clean the vehicle and clean the tires before the kidnappers burn the car.

I also trust you that you will not miss the material of the tire gap.

But what I thought at the time was that the temperature at which the rubber softened was only 80 degrees.

As the temperature rises, it becomes a viscous flow state!

In this process, it is possible that the material in the gap or surface of the tire is mixed with the softened rubber and covered by it, leaving the gap and the original position.

That’s what caused us to miss them! ”

“Huh? Can it still be like this? ”

“That’s a reasonable idea!”

“However, even if the temperature of the rubber is high, it will not become a pure liquid, it will only crack.

So the substances that can be covered by them must be very, very small.

Coupled with mixing with rubber, I’m afraid there is no way to find and identify!? ”

“It’s really difficult!”

Gao Ting smiled lightly

“I spent most of my afternoon this afternoon.

Luckily, I was able to find the red particles wrapped in a thin layer of rubber.

I used a variety of methods such as differential thermal analyzer, X-diffraction, infrared absorption spectroscopy, and Mössbauer spectroscopy to identify the particles multiple times.

Its main chemical components were found to be aluminum oxide, silica, iron oxide and calcium oxide.

It is also mixed with calcite, aragonite, diaspore trihydrate, opal and many more.

Everyone should know that these substances are all components of red mud…”

As soon as Gao Ting finished speaking, Zhou Yiting’s eyes lit up:

“The red mud particles are covered in tire rubber, so when the kidnappers burned the car, the red mud must have been on the tires.

Although there is red mud in the lake, the car is burned before it is pushed into the lake, so the red mud cannot come from the lake.

That said, Cadillac has most likely been to places where there is red mud on the ground!

Don’t…… Is it the factory that leaked red mud all those years ago?

The hiding place of the kidnappers, most likely near the aluminum factory?

Or, the area along the red mud leak? ”

“That’s right!”

Gao Ting nodded

“If I were a kidnapper, I would have chosen to be near the aluminum factory, or even hide directly inside the factory.

Because it is a well-known dangerous area, pollution, poison, corrosion labels, imprinted in everyone’s hearts.

People don’t go there easily! ”

“So, the place where the kidnapping took place and the hiding place of the kidnappers have the scope of investigation?”

Team Wang’s voice was extremely excited.

Sun Bureau also said excitedly

“This case, it seems that it is really going to be solved?”

Xiong Leilei patted Gao Ting’s shoulder heavily and said happily

“Brother, you are really powerful!

Even if the case investigation is strong, the physical evidence identification is so good!

Quickly say, what other surprise do you have, is it brother I don’t know? ”

And now the happiest one is Zhou Yiting.

She had almost foreseen that her father’s body would finally be found.

Even, there is a high probability that the murderer can be directly caught.

And all this thanks to the High Court.

“Uncle Sun, how about it, I’ll just say that the person I am looking for this time is very reliable and very powerful!”

Zhou Yiting looked at Sun Changming proudly.

“What did you find?”

Director Sun Changming was very unconvinced:

“Gao Ting is obviously the first to excavate, right?

If it weren’t for our Investigation Bureau yesterday, we discovered the talent of Gao Ting, and still helped him correct his name in the report, could you find him to help? ”

He knew that Zhou Yiting’s mouth was strong, and without waiting for her to refute, he said directly:

“Wang Mingjun, you immediately take two groups of people to the residence of the residents of Huba Mountain and the vicinity of the aluminum factory in the abandoned industrial zone to carry out reconnaissance!”

“Yes, Chief!”

Team Wang quickly took the investigators on the scene and left the laboratory.

Gao Ting and Zhou Yiting also followed.

Moments later, when all the investigators had left, there were only a group of technicians left in the laboratory.

Especially the technical captains, they watched the high court identify the red mud information, and their brows were tighter than the other.

“How did the High Court find this red mud granule?”

“I don’t know!

Before he judged the material of the carbonized particles, and also found hydrated lime and fungus spores from the gaps, although I also felt outrageous, but I could understand and accept it to some extent.

But how did he find and identify this red mud particles? ”

“Yes, how does he know which part of the tire is soft, there may be evidence?”

“This appraisal technique is also outrageous!

How many particles are tightly wrapped and stuck by rubber, and this can be identified? ”

“There is no problem with the identification results, the particles are indeed red mud!

But the identification process, I can’t understand it, I really can’t understand it! ”

“This high court is somewhat outrageous!”
