Chapter 529 The real cause of death(1/3)
People in this scientific world can indeed beat people's chests into pulverized fractures with their bare hands.
And those who can have such strength are not necessarily the middle-aged men that ordinary people imagine.
The murderer may be a female high school student who has practiced karate, or it may be an elementary school student who wears foot strength.
Once these scientific elements are mixed in, the murderer's gender, age, and occupation all become an unfathomable mystery.
Not even the most basic criminal profiling was possible.
The difficulty of detecting the case suddenly increased.
"No, that won't be the case."
Lin Xinyi was confused for a moment, but quickly rejected the idea:
"The injuries on the deceased were definitely not caused by unarmed attacks!"
"Why?" Officer Fang Gu cast a curious look.
The answer is simple.
Because according to the laws of science summarized by Lin Xinyi in the past:
Supernatural forces do exist in this world, but these supernatural forces never appear in criminal cases.
Otherwise, how could the famous detectives survive?
The comminuted fracture may be caused by the Vajra Palm.
The sudden death from poisoning may be due to the magical power of five poisons.
The recording evidence may have been forged by a voice changer.
The person captured by surveillance may not be a real person, but may be disguised by someone else using disguise.
Even the murder chamber that famous detectives love to crack may be a fake secret room violently created by the murderer who jumped out of the window from a height of five floors.
Anyway...
If these supernatural forces are mixed into criminal investigation reasoning, it will be impossible to reason at all, and it can hardly be called a criminal investigation.
And this world is the world of detectives.
God will not embarrass these famous detectives and make them lose their jobs due to scientific reasons.
Therefore, Lin Xinyi can be sure that the heavy injuries suffered by the deceased's chest were not caused by the palm of a martial arts master.
However, such an answer cannot be said directly.
Fortunately, Lin Xinyi had a very likely guess as to the cause of death of the deceased.
So he did not rush to answer Officer Furuya's question, but silently picked up the file and carefully observed the close-up photos of various parts of the unknown body, especially the area where the ribs of the deceased's chest were comminutedly fractured.
"This is not an unarmed attack injury."
"It was a gunshot wound caused by a shotgun blast at close range."
Lin Xinyi finally came to a definite conclusion.
As he spoke, he pointed to the close-up photo of the deceased’s back:
"see it?"
"There is still part of the skin attached to the deceased's back, and on this part of the skin and flesh, there are multiple hole-like damages visible to the naked eye."
"This is the damage caused when the lead shot from the shotgun entered the chest, passed through the chest, and flew out from the back."
"What?" Officer Fangtani was slightly startled: "Are these holes on the deceased's back caused by shotgun blasts?"
"But, Mr. Lin..."
He took a closer look at the close-up photo of the deceased's back:
"Isn't this a hole made by maggots?"
"How can you be sure that they are shotgun holes?"
There were indeed many holes in the deceased's back.
But there were many tiny maggots crawling in those holes.
They drilled in and out of these holes, constantly gnawing at the flesh and blood of the corpse.
At first glance, one would subconsciously think that these holes were chewed out by these little guys.
"This is the difficulty in identifying gunshot wounds on highly decomposed corpses."
Lin Xinyi explained calmly:
"On fresh corpses, the identification of gunshot wounds can be said to be very simple."
"You don't need to analyze the shape of the injection port like a forensic doctor, and you don't need to know how to observe phenomena such as the embedding of gunpowder particles and the adhesion of gunpowder smoke halo. Ordinary people can tell with their eyes whether the deceased was shot to death."
There was a small, heartbreaking hole in the body. It was obvious what the murder weapon was.
"But this simple visual identification method cannot be applied to this kind of white-bone, high-rot corpse."
"Because the bullet holes will be severely deformed after the flesh and blood rot and fester, their shape is very similar to the 'wormholes' drilled by maggots."
"And flies lay eggs on corpses, and they like to drill into the holes on the corpse."
Flies like to drill holes to lay their eggs.
This is because this allows their larvae to directly break through the skin barrier after hatching and more easily eat the flesh and blood of the corpse to obtain energy for growth and development.
Eyes, mouth, nostrils, ears, and some weird holes....
These are the places where fly maggots visit first.
When Lin Xinyi last solved the "Chigui Village Fire Festival Murder Case", he relied on the maggots found inside the back door of the deceased.
Same thing:
If there are bullet holes in a corpse, these bullet holes with delicious blood will definitely attract the flies that lay their eggs first.
Maggots will first hatch from the tunnel inside the bullet hole and eat the flesh and blood around the tunnel.
Over time, the maggots will eat all the meat.
Naturally, the bullet holes in this piece of meat no longer exist.
Even if the flesh and skin at the shot site has not been completely chewed away, like this corpse now, bullet holes can still be seen in the remaining skin.
These bullet holes have long been deformed, expanded, and changed in shape due to the decay of flesh and blood and the erosion of maggots.
It no longer looks like a bullet hole, but more like a wormhole made by maggots.
"If there are clothes of the deceased left at the scene, the bullet holes in the clothes can be used to identify gunshot wounds."
"But in this case, the deceased..."
The deceased had no clothes on him at all.
Not only was there no clothes, the deceased's ID, cell phone, wallet, and other personal belongings were not left at all. It seemed that they had all been taken away by the murderer.
Only an empty cash box was left at the scene.
There was also an unknown female corpse that was so decomposed that it was difficult to identify the wounds.
"No clothes of the deceased were found at the scene."
"Shotshot holes can easily be confused with maggot infestation."
"And the chest ribs have multiple comminuted fractures..."
"It is indeed possible that it was caused by a bare-handed strike."
"In this case, it is understandable that there will be a misjudgment."
As Lin Xinyi talked, he came to understand a little bit about the colleague who misjudged the cause of death.
But he still remained a bit dissatisfied because:
"The fracture shapes of comminuted fractures caused by shotgun blasts and comminuted fractures caused by bare-handed blows are definitely different in detail."
"As long as you observe carefully and analyze patiently, it is not difficult to distinguish between the two."
As he spoke, Lin Xinyi took out another close-up of the deceased's ribs:
"These comminuted fractures are not ordinary fractures. The fractures are all accompanied by some inconspicuous round bone defects."
"This round fracture defect is the mark left on the bone when the lead shot passes through the human body."
"Look carefully at the size of the distribution area of the shotgun pellets, combined with the fact that the pellets did not remain in the human body, but all pierced the chest and passed out from the back."
"It is not difficult to prove that the murderer shot the deceased in the front chest from a relatively close distance."
"So the area where these lead shot spread is not too large."
"And the projectile itself has enough kinetic energy to penetrate the human body, pierce the back and fly out."
"I see..."
Officer Furitani followed the instructions and observed carefully, and sure enough, he discovered small round bone defects from the fractures of the corpse.
