Chapter 626 An Unexpected Discovery

Why do you say that?

Just because there weren't any fingerprints on the shards of glass.

Whether these fragments are broken intentionally or accidentally and left on the road, normally they will leave fingerprints.

Wine bottle fragments should not have only one person's fingerprints. Things like wine bottles go through many links from manufacturing to sales, and people in these links may leave fingerprints on the bottle.

Now technicians have not found any fingerprints on the bottle fragments, which means that the bottle has been wiped by someone else and all the fingerprints on it have been removed.

Who would do this, only the murderer!

So Chen Yan believed that these bottle fragments were most likely left by Wang Xu's murderer, and why did he break the bottle?

Chen Yan's speculation seems to have come true.

"What about the cleaning lady who reported the crime? What did he say?"

"He determined that there were no bottle fragments on the road the day before the incident. These bottle fragments were swept from the road to the side of the road and were discovered before he called the police."

"You're telling me that these bottle fragments were still on the road before the cleaning staff cleaned them up?"

"Yes, it was just a day ago. The cleaning staff remembered it very clearly. She even remembered the approximate location."

Zhang Chaoyang took out a sketch: "At that time, these fragments were not in one place, but scattered at about three points on the road."

Looking at the distribution points of the three fragments on the sketch, the originally vague guess in Chen Yan's mind became clearer and clearer.

Gradually, a clear reasoning and judgment was formed, but the position of the three points was somewhat deliberate.

From the direction of Changjiang Road to Huanghe Road, there are two points where glass fragments are distributed, about 20 meters apart from each other. The other point is in the direction of Huanghe Road to Changjiang Road, distributed between the two points on the opposite side.

There are glass fragments distributed on both sides of the road, and they are relatively concentrated, and the distribution is so regular, and traces have been cleaned on the fragments. Why did the murderer do this?

What is the effect of this, and what does the murderer want to achieve?

Chen Yan frowned and thought for a moment: "Let's go and restore the scene."

Since you can't figure it out, let's reconstruct the scene and see what the murderer did for this purpose.

No need to go to any extra trouble, there is a parking lot in the backyard of the Second Detective Squadron, and you can simulate the road conditions on Binhe Road by randomly drawing two markings.

Binhe Road is a auxiliary road connecting Changjiang Road and Huanghe Road. The lanes are not wide, with only one lane on the left and right.

Soon, the corresponding scene was rearranged. Zhang Chaoyang looked at Chen Yan and saw him nodding. Angel said on the intercom: "Start."

At the command, a car in the distance was driving at a constant speed. A cone directly in front indicated the glass fragments. The driver of the car was Wang Gang. He was now simulating the state of Wang Xu's driving at that time.

In the middle of the night, a pile of glass fragments was found directly in front of the empty riverside road. What would a normal driver do?

Just push it over?

That was what an idiot did, so Wang Gang lightly swerved the vehicle from the right side of the road to the left side, avoiding the first cone, which was the first pile of wine bottle fragments.

But just as the vehicle drove over, another cone appeared in front of Wang Gang. At this time, Wang Gang had only one choice, which was to apply the brakes to slow down, then turn sharply and return to the road on the right.

At this time, the speed of the vehicle driven by Wang Gang was already very slow, less than 20 kilometers per hour. However, after Wang Gang turned around again, another cone appeared, and because the distance between the cones on both sides of the road was relatively close, Wang Gang could only step on it again. Apply the brakes, slow down, and turn left.

However, because the distance between the front and rear was too short, Wang Gang was unable to turn the wheel in one go. He had to stop halfway, fall backwards, and turn the steering wheel twice to avoid the cone again.

Seeing this scene, Chen Yan, Zhang Chaoyang, and Liu Qingshan all widened their eyes and looked at the car driven by Wang Gang stopped in the middle of the road.

Everyone followed Chen Yan and investigated more than forty cases in the past two years. Their experience has already changed, so of course they can see something fishy in it.

After Chen Yan suggested reenacting the fragments at the scene, Zhang Chaoyang sent people back to Binhe Road to conduct detailed distance measurements of all the glass fragments.

Moreover, the model of the vehicle driven by Wang Gang was exactly the same as the model of the vehicle driven by Wang Xu at the time of the incident.

In other words, the distance between the cones at the restoration site perfectly represents the distance between the glass fragments at the crime scene, and the turning radius of the vehicle driven by Wang Gang is exactly the same as that of the vehicle driven by Wang Xu.

The consequence of this is that Wang Xu should have... no, he must have parked his car on Binhe Road on the night of the incident.

The parking method was carefully planned by the murderer, and it may have two purposes.

The first is to force Wang Xu to stop the car and then implement the murder plan.

Second, fake the scene of the crime committed by an acquaintance to confuse the police’s investigation direction.

And it is obvious that the murderer's goal has been achieved. All the early detection directions of Chen Yan and others were centered around Wang Xu's acquaintances.

But now it seems things have changed.

Liu Qingshan walked to the car and said in a deep voice: "Is this how the murderer made Wang Xu stop the car?"

This is a reconstruction of the crime scene, so there is nothing wrong with it. There is certainly nothing wrong with Liu Qingshan's judgment.

"But if the murderer is not an acquaintance of Wang Xu, even if the other party stops the car, the door handle is locked at this time. How did the murderer get in the car?"

"In addition, we found at the crime scene that there was no struggle before Wang Xu was killed. Although he was knocked unconscious by ether, if the other party did not know Wang Xu, could he easily stun Wang Xu?"

Liu Qingshan’s words revealed many people’s questions.

Chen Yan smiled, stepped forward, and checked the location of the vehicle: "Actually, it is precisely because of this that we can confirm that the murderer who killed Wang Xu is probably not an acquaintance of his."

"The location of the bottle fragments at the scene allows us to confirm that Wang Xu was forced to stop the car out of desperation."

"But if the murderer is really familiar with Wang Xu, does he still need to set up these obstacles for Wang Xu to stop?"

Um?

yes.

Why did the other party ask Wang Xu to stop the car in this way? It was because the murderer probably didn't know Wang Xu and there was no way to make him stop the car.

Assuming that the murderer is Wang Xu's friend or acquaintance, he doesn't need these methods at all. He only needs to wave to Wang Xu to stop the car.

"But if the other party doesn't know Wang Xu, how did he get in the car?"

"Don't forget Wang Xu's profession."

"Profession?"

Chen Yan nodded: "Wang Xu is a project supervisor. According to the clues we have obtained from the current investigation, we can confirm that Wang Xu likes to accept some red envelopes or gifts such as tobacco and alcohol during his daily work."

"Wang Xu is actually less wary of strangers than ordinary people, because in the process of project supervision, he may receive red envelopes from anyone. It doesn't matter to him whether he is an acquaintance or not. What is important is that the other party can It cannot bring him any benefit.”

"If I were the murderer, I just need to put on a safety helmet, emphasize my identity as a construction worker, and hold two pieces of Huazi in my hand. Will Wang Xu let me get in the car?"

Um?

Liu Qingshan and others were slightly startled. What Chen Yan said seemed to make sense.

Especially for contractors and construction workers, Liu Qingshan and the others actually come into contact with quite a few.

Each grassroots detective unit attaches great importance to the management of construction sites within its jurisdiction. Sometimes when they go to inspect, the other party likes to stuff some cigarettes.

Most people don't think it's a big gift, so smoking a cigarette is nothing.

Therefore, there is a high probability that Wang Xu will let the other party get on the bus.
