Section 379

This question is quite explosive in the whole approach to science.

Since it is not in the car... Zhou Chen's eye of insight falls on the outside of the car.

"Huh?"

Zhou Chen squatted down, staring at the side of the car.

His eyes were fixed on the rear door of the car.

His sight slowly moved, looking at the car body above the tire and the side outer panel of the trunk.

"Such a clean... line!"

Zhou Chen pointed at the side of the car, from the rear door to the end of the trunk.

Yang Xu and the guards looked at each other, and the two police kings squatted down and observed carefully.

The car was black, and it had not been washed for many days.

Anyone who has a car knows that dust easily falls on the car body.

These dusts are hard to see if you don't get close... .......

When you get close, especially for black cars, it will be very obvious.

Strangely, the whole car looks like there is a layer of dust.

There is only a very clean trace from the door to the side of the trunk.

The dust on it is gone!

The width of this mark is 7 to 8 centimeters and the length is about 50 centimeters.

Zhou Chen's eyes approached the car body, getting closer and closer, and he said, "Call the forensic doctor."

Twenty minutes later, the forensic doctor from City E arrived.

"Check the car body."

Zhou Chen pointed to the "clean" mark on the car body.

The two forensic doctors looked at each other and followed the command to check the mark.

But through the magnifying glass and even the microscope, no suspicious objects were found.

"How could there be none?"

Zhou Chen frowned, "Where is the cowhide that was used to hold the body?"

"Evidence room." The guard said.

The police have a special evidence identification agency responsible for the collection, inspection and technical analysis of on-site evidence.

Evidence identification department!

After everyone arrived, the cowhide that had "strangled" a person alive was placed in front of Zhou Chen.

"Restore the original state before the autopsy." Zhou Chen ordered again.

The two forensic doctors began to work, putting fillers into the entire cowhide to restore it to the "bag" 2.7 shape when the cowhide was first found.

Zhou Chen, with his eyes of insight turned on, looked at the cowhide again.

Soon, he found a trace.

This trace was very similar to the trace of dust on the suspect vehicle.

The length of the trace was also exactly the same.

When the forensic doctor examined the cowhide, he found nothing.

"Is there such a glue?"

Zhou Chen looked at the forensic doctors and asked, "When it is used, its stickiness is very strong. It can stick to certain objects and can hold up objects weighing 70 to 80 kilograms. But when it encounters air, it will not stay for a long time, and the stickiness will disappear, causing the stuck objects to fall off. This glue can also evaporate on its own without leaving any traces?"

After hearing this, the two police kings and the two forensic doctors were stunned.

Is there such a glue in the world?

The answer is... yes! .

Chapter 365 What are you talking about (5 more)

"Single-component moisture-reactive polyurethane glue."

"This glue is very sticky and can completely stick to objects in about half a minute, but it also has a bad feature. It evaporates very quickly after contact with air."

"This glue is often used in some closed spaces. If used in an environment with air circulation, for example, 10 grams of this glue can evaporate completely within 30 to 45 minutes without leaving any trace."

"But within about 20 to 30 minutes, in the air, it still has considerable stickiness."

"Exceeding this time period, it will lose its stickiness due to contact with air evaporation, and the adhesive will fall off."

A forensic doctor looked at Zhou Chen with an expression of seeing a ghost.

Yang Xu and the guards also looked at Zhou Chen as if they had seen a ghost.

We all have human brains. Isn't your excellence a bit too much?

Let the fools talk about the awesomeness... Zhou Chen looked at the forensic doctor calmly and said, "Prepare some glue in your mouth."

An hour later.

A forensic doctor brought the glue to everyone.

Zhou Chen asked the forensic doctor to fill the "cowhide bag" with the weight of 27 people, in a ball shape.

Then the suspected vehicle was driven over.

Zhou Chen took a brush and brushed a line of glue on the side of the car body.

Pick up the "cowhide bag" and stick it on the car body with glue.

One second, two seconds, three seconds...half a minute later.

Zhou Chen let go.

The "cowhide bag" weighing about 60 kilograms was firmly attached to the car body.

Zhou Chen personally drove the car for an experiment and drove for a few minutes.

The "cowhide bag" was still firmly attached to the car body and did not fall off.

Stop the car and Zhou Chen got out of the car.

Everyone stood outside the car like a sculpture, looking at the "cowhide bag".

Time passed slowly, about twenty minutes.

With a click, the ‘cowhide bag’ fell off the car body by itself.

Everyone’s expression became complicated, Yang Xu and the guards smiled bitterly.

The two police kings were slapped in the face by Zhou Chen.

The two forensic doctors showed an expression of sudden enlightenment on their faces, so that’s it.

Everyone imagined a scene.

Someone took the body wrapped in cowhide and stuck it to the car body in a corner away from surveillance.

Moreover, he calculated the time and knew that the driver would drive away later.

When the driver drove on the road, the vehicle drove for a while, and the ‘cowhide bag’ containing the body fell off the car body.

The body was dumped!

The driver was then brought in.

Zhou Chen's interrogation revealed that the place where he parked his car that night was about ten kilometers away from the scene of the body dumping.

The crowd came to an open-air parking lot.

The parking space of the suspect vehicle was a bit strange.

Parking lots are usually vertical parking spaces.

In front of us is a horizontal parking space in the parking lot.

When the vehicle was parked, it was next to a half-person-high green belt on the right.

There was no surveillance around.

Suppose someone entered here from the green belt and secretly put a "cowhide bag" on the vehicle, it would be difficult for the driver to find out.

Zhou Chen stood in the parking lot, watching the two police kings investigate the scene.

"Found it." Yang Xu shouted.

Zhou Chen walked over and saw Yang Xu squatting on the green belt, pointing to the ground soil.

There were several footprints on the soil!

It can be guessed that they should be the footprints left by the murderer when he dumped the body.

Based on the size, depth, and shoe shape of the footprints, it can be roughly inferred that the murderer's height is about 175 to 182 and his weight is between 70 kg and 80 kg.

Through the footprints, we went to the other side of the green belt, which was also an open-air parking lot.

This green belt just separated the two parking lots.

"The other party should have driven here at the time."

Yang Xu reasoned, "Sitting in the car, we can also observe the drivers of some vehicles on the opposite side, calculate the time, and then stick the cowhide bag on the suspected vehicle to create a body dump."

"There is a question."

The guard was puzzled, "Why did he go to so much trouble? Can't he just dump the body in the parking lot?"

This is indeed a question.

No one can guess why the murderer did this.

The police began to investigate the parking lot, looking for the suspected vehicle that the murderer may have driven.

How to find it if there is no surveillance around?
