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

In the laboratory!

Everyone was stunned when they heard that Highgarden's second discovery was red mud.

Even Xiong Leilei found something wrong:

"Brother, can red mud be considered a discovery?!

The previous red mud leakage accident resulted in a lot of red mud in the lake, which caused pollution of the lake water and corroded the environment. Do you know this?

The car has been soaked in the lake for so many years. Isn't it normal to find red mud on the tires?

How could this be a clue?"

"That's right!"

He Fudao was also puzzled and said:

"You should have read our previous appraisal report.

We've also found red mud on car tires and even on car roofs.

But this cannot be used as a clue at all!"

Hearing the doubts of the two people, Gao Ting smiled and said:

"If red mud is found on the car body and tire surface, it cannot be used as a clue.

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

"ah?"

"Rubber interior?"

"What's the meaning?"

"How did the red mud get into the rubber?"

"Highgarden, please explain!"

……

"it's actually really easy!

Gao Ting said:"This involves the specific process of the kidnapper dumping the car."

After the kidnappers succeeded in kidnapping, they should have driven the Cadillac to the hiding place they had found in advance.

Because they wanted to make a blackmail call to the Zhou family immediately to prevent the Zhou family from finding someone to call the police directly.

After that, they had time to dispose of the bodies of the three deceased and arrange to sink the car.

They must have driven the Cadillac to the lake, poured gasoline on it, burned it, and then sunk it."

"This should be the process!"

Lin Xiaoxiao asked while recording in a small notebook:

"But does this have any impact on the identification of physical evidence and the red mud you found?"

"Of course! Gao

Ting smiled and said:

"As we all know, in order to increase friction, car tires are patterned.

And these concave patterns can easily squeeze in fine gravel and other substances."

"However, we have also thought of this!"

A technician said:

"The wheel gap is an area that needs to be focused on during the forensic process.

In many cases, the murderers were arrested because clues left in the gaps in the wheels revealed that they had been to the crime scene.

But in this case, we searched for all the gaps in the wheels.

But only ordinary sediment and other materials were found.

And the quantity is very small!"

High Court nodded again:

"I also discovered this!

Given that very little material was found on the wheels, the kidnappers should have washed the vehicle and cleaned the tires before burning the car.

I also believe that you will not miss the material in the tire gap.

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

As the temperature increases, it will become a viscous flow state!

During this process, is it possible that the material in the tire gap or surface will be mixed with the softened rubber and covered by it, leaving the gap and its original position?

That's why we missed them!"

"ah? Can it still be like this?"

"This idea is somewhat reasonable!"

"However, no matter how high the temperature is, rubber will not turn into a pure liquid state, but will only crack.

Therefore, the material that can be covered by them must be very, very small.

Plus, it’s mixed with rubber, so I’m afraid there’s no way to find and identify it! ?"

"It is indeed very difficult!

Gao Ting smiled lightly and said :

"I basically spent the whole afternoon on this.

Fortunately, I finally found the red particles wrapped in a thin layer of rubber.

I used differential thermal analyzer, X-ray diffraction, infrared absorption spectroscopy, Mössbauer spectroscopy and other methods to identify the particles many times.

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

It is also mixed with calcite, aragonite, gibbsite, opal, etc.

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 were covered in tire rubber, so the red mud must have been on the tires when the kidnappers burned the car.

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

In other words, Cadillac has probably been somewhere with red mud on the ground!

Could it be...the factory that leaked red mud many years ago?

The kidnapper's hiding place is probably near the aluminum factory?

Or the area along the red mud spill?"

"That's right!"

Gao Ting nodded and said:

"If I were a kidnapper, I would probably choose to hide near the aluminum factory, or even hide directly in the factory.

Because it is a dangerous area known far and near, and the labels of pollution, toxicity, and corrosion are imprinted on everyone's mind.

No one would go there easily!"

"So, both the place where the kidnapping took place and the place where the kidnappers were hiding are within the scope of investigation?"

Captain Wang's voice was extremely excited.

Ju Sun also said excitedly:

"This case seems to be really going to be solved?"

Xiong Leilei patted Gao Ting's shoulder heavily and said happily:

"Brother, you are so awesome!

It doesn’t matter that the investigation of the case was excellent, but the identification of physical evidence was so impressive!

Come on, tell me, do you have any other surprises that I don’t know about, brother?"

The happiest person now is Zhou Yiting.

She has almost foreseen that her father's body will finally be found.

There is even a high probability that the murderer will be caught directly.

And all this is thanks to Gao court

"Uncle Sun, what do you think? Let me just say that the person I found 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:

"We obviously discovered Highgarden first, okay?

If our investigation bureau hadn't discovered the talent of Gao Ting yesterday and helped him clear his name in the report, would you have been able to find his help?"

He knew that Zhou Yiting had a sharp mouth, so he said directly without waiting for her to refute:

"Wang Mingjun, you immediately take two groups of people to conduct investigations where the residents of Huba Mountain lived and near the aluminum factory in the abandoned industrial zone!"

"Yes, Director!"

Team Wang quickly left the laboratory with the investigators on site.

Gao Ting and Zhou Yiting also followed.

A moment later, when all the investigators left, only a group of technicians were left in the laboratory.

Especially the technical captain They looked at the information on the identification of red mud by High Court, and their brows became more and more furrowed.

"How did High Court discover these red mud particles?"

"I do not know!

He had previously determined the material of the carbonized particles and found slaked lime and fungus spores from the gaps. Although I also felt that it was outrageous, I could still understand and accept it to a certain extent.

But how did he discover and identify these red mud particles?"

"Yes, how does he know which part of the tire is softened? Maybe there is evidence?"

"This method of identification is also outrageous!

A few particles are tightly wrapped and stuck in rubber. Can you identify it?"

"There was nothing wrong with the identification results. The particles were indeed red mud!

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

"This High Court is somewhat outrageous!"
