On The Day Of My 100th Blind Date, I Arrested My Date Chapter 180

Click.

Projection switching.

There are two sets of tire marks.

"We collected a total of two sets of tire tracks at the scene."

"The first set of tire marks are the tire marks of a tricycle."

"We compared the tricycles of Wang Fugui and his wife, and we can confirm that the tire tracks on the tricycle belong to them."

"The other set of tire tracks is weirder."

"Everyone look at the screen..."

Click to switch the screen.

Appeared above are four tire marks.

"Of the four tire marks, the two in the middle are the same, but the two on the sides are not."

"Team Leader Chen, the general situation at the scene is basically this."

Chen Yan nodded.

Get up and walk to the whiteboard.

"According to the current situation we have, we first need to confirm the identity of the deceased."

"Judging from the degree of physical damage to the deceased, the murderer either had a deep hatred with the deceased, or deliberately damaged the body to mislead our investigation."

"Now, let me arrange the next stage of work."

"Captain Zhao, please work hard. Divide all the detectives of the fourth detective team into five groups and follow up my next deployment."

Zhao Haiyang stood up and saluted, "Yes, Team Leader Chen"

"The first group is responsible for tracing the origin of the necklace on the neck of the deceased."

Click.

The screen switching is exactly the picture of the necklace on the neck of the deceased's body.

"This necklace is the only thing on the body of the deceased."

"Necklace material, gold, and here... branded."

"The first group is responsible for finding the origin of this necklace, who bought it, and where did it come from."

"When the murderer killed the deceased, it was impossible not to notice the existence of this necklace."

"However, he still kept this necklace, which shows that the possibility of the other party seeking wealth is relatively small, and the possibility of vendetta and love killing is relatively high."

"Finding the necklace makes it possible to confirm the identity of the deceased."

"The second group visited various plastic surgery hospitals in Shen City."

Click.

The projection screen switched again: "Look here, the nose of the deceased was cut off by a sharp blade."

"The nasal bone is exposed, but there are friction marks on the nasal bone of the deceased. From this point of view, the deceased should have undergone nose plastic surgery before his death."

"Track down all the hospitals in Shenshi that can perform nose plastic surgery, and see if you can find out the identity of the deceased."

"At the same time, the third group followed up the situation of the deceased's broken fingers. Judging from the scars on the deceased's toes, it was similar to the operation performed in the early years. In major hospitals, all people who had undergone the fourth toe removal operation were inquired. Check your identity."

"The fourth group... trace the origin of the thorns in the deceased's body."

The projections are replaced again.

"This kind of thorn bar is a common thorn bush in the wild, but this kind of thing, because it has sharp thorns, even in rural areas, ordinary people will not collect it for burning fire."

"So, when it's okay, no one makes this kind of thing."

"Check it out, where is there such a thorn bush near the place where the corpse was thrown."

In fact, judging from Chen Yan's judgment, the fatal injury of the deceased should be that after being stabbed by a thorn bar, he bleeds too much and died.

The murderer was so cruel, what kind of hatred did he have with the deceased?

In addition, the deceased had welts intertwined, both new and old.

It shows that the deceased may have been bullied for a long time before his death.

When it comes to the investigation of the thorns, the faces of many detectives are not very good-looking.

Such a brutal crime scene is extremely rare.

The murderer's behavior can already be described as perverted.

"The fifth group, focusing on tracing tire tracks."

Chen Yan sorted out his thoughts and continued to deploy the work: "On the one hand, the tricycle of the reporter Wang Fugui and his wife must be inspected."

"Including whether there is friction between the iron cage and the box in the carriage, and whether the tire marks match the scene of the tricycle under different load-bearing conditions."

Although Wang Fugui and his wife were the reporters, but there was no surveillance at the time, and the two were also suspected of committing the crime.

So, check the tricycles they use.

On the one hand, if they shouted to catch the thief, then they should use the iron dragon transported by the tricycle.

Then, during transportation, the iron cage is bound to come into contact with the box of the tricycle.

In this way, it is easier to find some clues.

On the other hand, even if the other party has been prepared, such as wrapping the cage with something like a quilt to avoid bumping.

However, the weight of the iron cage plus the deceased is at least 150 kilograms.

In this case, the tricycle's increased load of 150 kilograms is definitely different from the tire traces when it only carried Wang Fugui and his wife.

"And a second set of tire tracks."

Click.

Switching the screen, Chen Yan pointed to the second set of tire marks: "This set of tire marks, the two tire marks in the middle are the same, and they should be motorcycle tire marks."

"On both sides, there are different tire marks, but the depth of the indentation is basically the same."

"So, it's very likely a motorcycle pulling a cart, and the tires on both sides of the cart are not the same."

This is a good explanation.

If the tires of the trolley are severely worn on one side, it is also possible to change to a tire with a different pattern.

After all, trolleys are pushed manually.

The speed is not fast, and even if the tire patterns on both sides are inconsistent, there will be no rollover.

After the five tasks were arranged, everyone took the lead.

In the conference room, there are only Chen Yan and Zhao Haiyang.

This case is somewhat unusual.

The murderer's ruthlessness far exceeded Chen Yan's imagination.

Its approach is even a bit perverted.

The marks on the deceased's body also indicate that the deceased may have been often bullied during his lifetime.

However, this person is very beautiful, otherwise, he would not have undergone nose plastic surgery.

And iron cages.

The place that should have been locked has been welded.

Judging from the traces of welding, it should be the situation in the past few days.

However, is welding such a thing accessible to ordinary people?

Chen Yan looked at Zhao Haiyang: "Captain Zhao, he is still separating a group of people to follow up all the welding shops within 100 kilometers of the place where the corpse was thrown."

"The other party can weld the iron cage to death, so there must be welding equipment."

"This kind of thing, most people don't have it."

Zhao Haiyang nodded: "Okay, I'll make arrangements now."

Leaving the conference room, Zhao Haiyang was busy making arrangements.

afternoon.

Group 5 was the first to return the message.

"Team Leader Chen, the tricycle of Wang Fugui and his wife, the inspection results have come out."

Click, the screen projection is turned on.

"We checked Wang Fugui's tricycle and found no related bump marks on the box."

"At the same time, we compared the tire indentation depth of the tricycle."

"It fits the situation of the tricycle carrying Wang Fugui and her wife."

Chen Yan nodded: "That is to say, the possibility of Wang Fugui and his wife using a tricycle to transport the iron cage is basically ruled out?"

The fifth group leader nodded: "It's true."

"Also, Wang Fugui and his wife are still in shock."

"When we went to visit, both of them stuttered."

"Obviously haven't recovered from the shock caused today."

Indeed, I went to the net fishing early in the morning, and a corpse came to the net.

Moreover, the corpse was brutally destroyed...

"The other group of car marks, how is the investigation?"

"The investigation results of this group of car marks have made great progress."

"In the afternoon, we simulated the scene of a motorcycle and a trolley on the scene."

"At the same time, a driver drove a motorcycle and put the weight equivalent to the iron cage and the corpse into the cart..."

"It turns out that the indentation is a little shallower than the traces on the spot!"

Shallow indentation?

What's the meaning?

A shallow indentation means that the cart or motorcycle is not carrying enough weight.

What is the cause?

This kind of simulation does not mean that it can be done by just finding a cart.

Such things as car marks~www.mtlnovel.com~ show much more information than expected.

First of all, it is the tire pressure of the tire. No matter how the load changes, through the tire marks, it can actually be inferred that the normal tire pressure of the tire.

Because the load weight changes, the tire contact area increases.

This increase in area has two aspects, one is the tire sidewall contacting the ground, the other is the tire landing point, and the front and rear ground contact areas are increased.

Through the model calculation, there is a fixed calculation method for the ground contact area of the front and rear of the tire and the sidewall for different load capacities.

This is tire track analysis.

Actually, it is a science.

At present, this method is very mature.

So there are only two reasons for this problem.

Chen Yan frowned slightly and looked at the person in charge of the fifth group: "You mean...the corpse thrower is a fat man with a large weight...or is it that the person throwing the corpse is not alone?"
