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

Chapter 368: A Button

Chapter 369 A Button

The scratches are fine and the marks left are not particularly deep.

However, being able to leave scratches on the bone shows that the murderer used a lot of force when stabbing him!

Under the blessing of the visual gene lock, the scratches on the ribs gradually magnified in Chen Yan's eyes.

The first is the judgment of the technique of holding the knife in the palm of the hand.

The murderer stabbed the deceased in the back of the heart from behind.

The sharp blade pierced the back of the chest, pierced the heart, and the tip of the knife finally hit the inside of the ribs, leaving scratches.

This kind of penetrating injury shows that the murderer was very strong at that time.

To achieve such a large force, the general method of holding a knife is not enough.

The force of holding the knife in the forehand and stabbing into the chest from the back is not so strong.

If you want to penetrate with a knife, you should hold the knife with your backhand.

From top to bottom, in one swoop!

With the help of the knife's inertia, the knife pierced through the back of the chest, then through the heart, and reached the ribs.

While observing, Chen Yan waved his right hand slightly, imitating the stabbing action of the murderer at that time.

Seeing Chen Yan's actions, Zhang Man knew what Chen Yan wanted to do.

Restoring the murder scene.

In this way, to a certain extent, the process of the crime scene can be judged.

Thus inferring some characteristics of the murderer.

Next is to analyze the direction of the scratches.

Chen Yan lay beside his ribs, carefully judging.

The knife cuts to the ribs, and from the beginning to the end, the deep and light marks are different.

Generally speaking, the scratches produced by any tool touching an object are from shallow to deep.

The same goes for the point of the knife touching the ribs.

From the first contact,

In the end, because of the blockage of the bone, the knife stopped moving.

Scratching is also a process from shallow to deep.

Observe carefully, the marks on the ribs start from bottom to top.

That's where it gets interesting.

The murderer held the knife in his backhand and stabbed the victim suddenly.

The direction of movement of the tool turned out to be from bottom to top...

what does that mean?

It means that the position where the murderer raises his hand to attack is shorter than the victim's chest!

Standing up, Chen Yan waved his arms towards the air.

After a while, Chen Yan looked at Zhang Man: Sister Zhang, please, let me simulate the scene of the crime.

Zhang Man nodded: Okay!

Zhang Man's height is 167, which is about the same height as the victim.

Standing behind Zhang Man, Chen Yan kept adjusting his position.

The right hand is holding a scalpel taken from the dissecting table in the backhand.

With Chen Yan's height, Zhang Man's back was stabbed with a knife. If the tip of the knife passed through the heart and pressed against the ribs, the direction of the rib scratches caused by the knife point should be from top to bottom, from shallow to deep.

Chen Yan slowly bent his legs, lowering his height.

In my mind, Zhang Man's body seemed to be slowly fading away.

Only a skeleton remains.

The third rib protects the heart, and the scalpel in his hand is constantly adjusting its position.

Pooh!

The tip of the knife went down and pierced into the back of the chest.

Then it penetrates the beating heart and hits the third rib!

creak!

The ear-piercing sound of rubbing seemed to resound in Chen Yan's mind.

Everything happens in imagination.

The scratches, from bottom to top, correspond exactly to the scratches on the skeleton.

At this time, Chen Yan was almost squatting on the ground.

One meter two!

At this time, Chen Yan's arm was 1.2 meters high, just under Zhang Man's armpit.

And Chen Yan's height at the moment is 1.4 meters!

The murderer is about 1.4 meters tall!

And... the tools he used... are very special!

very special.

Yes.

Why special?

Because the ribs of the human body are different from those of ordinary animals, especially the pork chops, lamb chops or steaks that people often eat.

In general reptile mammals, the ribs protect the internal organs and are not completely wrapped.

In the abdomen, from top to bottom, it is gradually opened.

However, humans, as well as mammals that can walk upright, such as monkeys, orangutans, and baboons, have ribs that are fully surrounded.

Starting from the sternum, it spreads in a circle, forming a cage shape, protecting all vital organs in the ribs.

Therefore, the murderer killed the victim even with a knife from the back.

If the knife used by the opponent is just a sharp knife that we usually use, then it will definitely touch the ribs on the back.

That is to say, if a general knife wants to penetrate the chest cavity from the back of the human body, pierce the heart, and injure the inner side of the third rib, it must first injure the ribs on the back.

But Chen Yan did not find any scars on the back ribs of the skeleton.

Therefore, the knife used by the murderer is very thin and long.

The width is very narrow so that it can penetrate the ribs behind without hurting the ribs.

The length is sufficient to penetrate the entire chest cavity and damage the inner ribs in front.

So, will the murderer specially create a slender knife specifically to cause this kind of injury?

Unless the other party is a superb blacksmith, but in modern society, blacksmithing...

It's not that there is no such possibility, but Chen Yan thinks the possibility is very small.

Don't forget, Chen Yan once received a tool cognition map rewarded by the system.

Knives that can cause such injuries are readily available.

In reality, the most used and most common is... a ham slicing knife!

A kind of western food knife.

Slender and sharp.

With such a judgment, Chen Yan focused his attention on the button found in the mouth of the skeleton.

a button!

After Zhao Kuo called the police, the on-site investigators of the detective team found an important physical evidence at the cemetery.

A black button with gold trim.

Ten years ago, when Zhao Kuo buried his father's ashes, he put a lot of funerary objects.

However, there must be no buttons inside.

According to local customs, a set of shrouds was buried in Zhao Kuo's father's tomb.

But there will be no buttons on the shroud.

It is a custom that the shroud is put on after death.

Because after death, it is impossible to wear clothes like normal people, so the structure is special.

In other words, the button could only have been brought in by the deceased, not in the cemetery.

The buttons are obviously of excellent quality.

According to Zhang Man's judgment, the deceased should have died 4 years ago.

After such a long time in the past, the buttons still look like new, which shows the quality of the buttons.

Captain Liu, have you found the source of the buttons?

Liu Qingshan Yaoyao headed: I asked several detectives to go to the market to ask, and they all said that they had never seen this kind of button.

In this case...

Captain Liu, in this way, it is impossible for this button to appear in the grave for no reason.

So, finding the source of this button is likely to be an important clue to solve the case.

Compared on the Internet, the quality of this button is very good and the gold edge is gold-plated.

A button is trimmed with gold, and its owner must not be an ordinary person.

Go to the Internet to compare, especially on some foreign websites, and compare some special clothing.

There is no such luxurious button culture in Huaguo.

On the contrary, in foreign countries, some aristocrats left over to the present pursue the inheritance of clothing, and have high requirements for buttons, brooches, etc. clothing.

After all, buttons and suits are originally Western clothing, and it was only introduced to China in the past 100 years.

Moreover, the knife used by the murderer is likely to be a ham slicing knife. Focus on checking some chef's accessories to see if there are such button decorations.

In the previous case, Chen Yan obtained a lot of information in this regard in the cognitive map of luxury accessories.

Okay, I'll arrange it now.

Case investigation is progressing.

The comparison results of the DNA information of the bones are still being compared.

The missing persons information database has been compared and nothing has been found.

Now, the detectives on Liu Qingshan's side are comparing the information in the DNA database.

Results are expected this afternoon.

However, Chen Yan is not hopeful about this comparison.

After handling so many cases, there has never been a successful comparison in this DNA database.

The other is the analysis of organic matter in the cemetery.

This can determine whether the deceased entered the cemetery, whether it was a corpse or a skeleton.

This clue is clearly related to the button clue.

If the deceased was the skeleton itself when it entered the cemetery, the buttons may have been left behind by the murderer.

Even, the murderer was confusing the public at all.

And if the murderer entered the grave as a corpse, it would rot and ossify later.

Then, the buttons in the mouth of the deceased are likely to be clues left by the deceased intentionally.

After three hours, all the analysis is over!
