On The Day Of My 100th Blind Date, I Arrested My Date Chapter 368

Chapter 369 A Button

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

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

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

The first is the judgment of the hand holding the knife.

The killer stabbed the dead man in the back from behind.

The sharp blade pierced the back of the chest, pierced the heart, and the tip of the blade ended up on the inside of the rib, leaving a scratch.

This kind of penetrating injury was caused, which shows that the murderer was very powerful at that time.

If you want to achieve such a great strength, the general method of holding a knife is not enough.

The force of the knife in the forehand stabbed into the chest from behind is not so strong.

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

From top to bottom, swing out!

With the inertia of the knife, the knife pierced the back of the chest, then penetrated 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.

Restore the murder scene.

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

Thereby infer some characteristics of the murderer.

Next is to analyze the direction of the scratches.

Chen Yan lay beside his ribs and judged carefully.

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

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

The same goes for the tip of the knife touching the rib.

From the first contact, to the last because of the blocking of the bone, the tool stops moving.

Scratches are also a process from shallow to deep.

Carefully observe, the marks on the ribs, the shade changes are from bottom to top.

This is 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 raised his hand to attack is shorter than the victim's chest!

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

After a while, Chen Yan looked at Zhang Man: "Sister Zhang, please, imitate the situation at the crime scene with me."

Zhang Man nodded: "Okay!"

Zhang Man's height is 167, which is similar to the height of the victim.

Standing behind Zhang Man, Chen Yan constantly adjusted his position.

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

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

Chen Yan slowly bent his legs and lowered his height.

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

Only one skeleton remains.

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

puff!

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

Then pierce the beating heart and hit the third rib!

creak!

The harsh rubbing sound 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 about to squat on the ground.

One meter two!

At this time, Chen Yan's arm height was one meter two, just below Zhang Man's armpit.

And Chen Yan's height at the moment is one meter four!

"The murderer is about 1.4 meters tall!"

"And... the tools he uses... 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 rib is not fully encapsulated in the part that protects the internal organs.

In the abdomen, from top to bottom, it gradually opens.

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

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

Therefore, the murderer even kills the victim with a knife from behind.

If the knife used by the other party is only the sharp knife we usually use, it will definitely touch the ribs behind.

That is to say, if an ordinary 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 rib 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 narrow enough to penetrate the ribs on the back without hurting the ribs.

Long enough to penetrate the entire rib cage and injure the inside of the front ribs.

So, will the murderer specially create a slender knife 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 believes that the possibility is very small.

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

Knives capable of inflicting such injuries are readily available.

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

A kind of western knives.

Slender and sharp.

With such a judgment, Chen Yan focused his eyes on the button found in the skeleton's mouth.

A button!

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

A button with gold trim on a black background.

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

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 are no buttons on the shroud.

This is the custom, 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 originally in the cemetery.

The quality of the buttons is clearly excellent.

According to Zhang Man's judgment, the time of death of the deceased should have been 4 years ago.

After so long, the buttons still look like new, which shows the quality of the buttons.

"Liu team, have you found the source of the button?"

Liu Qingshan Yaoyao: "I asked a few detectives to go to the market to ask, and they all said that they have never seen such buttons."

In that case...

"Liu team, 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 detect the case."

"Go to the Internet to compare, the button is of good quality and the gold-edged composition is gold-plated."

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

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

In China, there is no such luxurious button culture.

On the contrary, in foreign countries, some nobles who have been left to the present pursue the inheritance of clothing, and have high requirements on buttons, brooches and other clothing.

After all, buttons and suits were originally Western clothing, and were 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 is such a button decoration."

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

"Okay, I'll arrange it."

The investigation of the case 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 in the afternoon.

However, UU Reading www.uukanshu.com Chen Yan is not hopeful for this comparison.

After so many cases, the comparison in this DNA database has never been successful.

Another is the analysis of organic matter in the cemetery.

This can determine when the deceased enters the cemetery, whether it is a corpse or a skeleton.

This clue is clearly related to the button's clue.

If the deceased entered the cemetery as a skeleton, the button may have been left by the murderer.

Even, it is the murderer who confuses the public.

And if the murderer enters the grave as a corpse, it rots and ossifies later.

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

After three hours, all the analysis is over!
