Dissection room.

Lin Shinichi and Asai Narumi had already changed into a triplet dissection suit and wrapped themselves tightly.

And this post-mortem is not anything else, but the equipment is good enough and complete.

Therefore, Lin Xinyi also specially used anti-cut gloves this time.

A layer of cut-resistant gloves over latex gloves is very useful when dissecting.

Because cut-resistant gloves are not as easy to be cut by a knife as latex gloves, wearing them can protect you as much as possible from being cut by a scalpel.

Moreover, it is resistant to cutting and slipping.

For example, when opening the chest cavity of the deceased, it is necessary to peel off the fat and muscle layer with the hands to both sides...

These cut-resistant gloves can help increase friction and make it easier to exert force, so that one of them can't grip tightly and let those human tissues slip out.

"Asai, put on the gas mask again."

As he spoke, Lin Xinyi put on a high-end gas mask for himself.

He rarely used this kind of luxury before, and basically wore a disposable mask and went into battle.

But now it's different... The situation in the identification class is that people are stupid and have a lot of money, and he doesn't need to help save money and materials.

So, after putting on a suit of high-end equipment, Lin Shinichi walked into the dissection room with Asai Narumi.

And the police officers who made the hand had already helped send the body of the deceased to the autopsy table in advance.

The young man, "Kenichi Matsubara", was lying quietly on the cold stainless steel dissecting table at the moment, waiting for someone to find the truth for him.

"Mr. Lin..."

Asai Narumi looked at the corpse that had already been examined by him, and finally couldn't help but ask curiously:

"Is Kenichi Matsubara's death really related to his father's violent abuse three days ago?"

"He died three days after his injuries and didn't show any serious symptoms in the meantime, is this possible?"

"Of course it is."

Lin Xinyi replied calmly.

And looking at Asai Narumi's eyes full of curiosity, his expression couldn't help but become serious:

"Asai, have you heard of crush syndrome?"

"Crush syndrome" Asai into a solid head jump.

Unlike Mao Lilan, a rookie assistant who has just started, Asai Narumi is a serious medical student at a prestigious school and has a deep enough medical foundation.

Without Lin Xinyi's detailed explanation, he can understand the professional knowledge mentioned by Lin Xinyi:

"Crush syndrome is a series of pathophysiological changes that occur after the squeezing of heavy objects for a long time in the muscle-rich parts of the human body is squeezed by heavy objects."

"The main clinical manifestations are acute renal failure characterized by limb swelling, myoglobinuria, and hyperkalemia."

"If left untreated, patients do die after a period of crushing."

Narumi Asai carefully recalled what he had learned about crush syndrome:

To put it bluntly, the body has been pressed by heavy objects for too long, and it has been pressed out of a fatal illness.

And this knowledge is not unfamiliar to him, and to most of the medical staff nowadays.

Because in the medical community, there was the earliest research on crush syndrome, and what made crush syndrome known to the world was the book.

This is mainly because...

There are many earthquakes in this book.

In the aftermath of an earthquake, it is not uncommon for people to be trapped in the rubble and squeezed by heavy objects for long periods of time.

Even if these victims are lucky enough to be rescued from the rubble by the rescue team, if they do not receive timely and professional treatment, they may die suddenly and "mysteriously" after a period of time due to crush syndrome caused by prolonged limb compression.

This can be a few hours or a few days.

In the opinion of those who don't know:

When the wounded were rescued, they were obviously fine, but why did they disappear after a few days of recuperation?

It was crush syndrome that caused their deaths.

And this problem has gone unnoticed for many years.

It wasn't until the Great Hanshin Earthquake in 1995, when rescuers discovered that many injured people had died suddenly of unknown causes after being rescued, that the medical community began to notice the existence of crush syndrome.

Therefore, in the current era, the medical community's research on crush syndrome has actually just begun.

In the past two years, Asai has been lurking on the island as a community doctor, and has not studied in a hospital or school, nor has he had access to the latest medical research.

Although he had learned about crush syndrome from the press, he did not know much about it:

"In the case of crush syndrome, the patient may indeed die suddenly after 3 days due to acute kidney failure due to deterioration of the condition."

"But... Wasn't the deceased a victim of domestic violence? ”

"He was injured by a blunt object, and he was not continuously squeezed by a heavy object, how could he get crush syndrome?"

Asai asked with some confusion.

"Haha... You can't think too restrictively. ”

Although the name of this disease is "crushing", in fact, direct blows to the limbs can also cause crush syndrome. ”

"Because violent blows can cause subcutaneous bleeding and muscle damage similar to or even more severe than heavy body squeezing."

"Severe injury to the body can lead to microcirculation disorders, tissue hypoperfusion, and aggravated damage to kidney function."

"Myoglobin damage caused by injury forms methaemoglobin casts in acidic urine and deposits them in the renal tubules, causing renal tubular degeneration and necrosis, causing acute renal failure."

“.....”

"In short, in terms of the formation mechanism, there is not much difference between 'squeezing' and 'beating'."

Lin Xinyi explained methodically:

"So in our forensics, no, not just forensics..."

"In the daily work of doctors, crush injuries caused by stick blows, punches and kicks are the most common."

"After all, natural disasters like earthquakes can't happen every day."

"And man's malice towards man is much more powerful than natural disasters."

"I see..."Narumi Asai quickly reacted:

"The deceased did not receive timely treatment after being subjected to domestic violence, so his condition continued to deteriorate during these 3 days, and finally died suddenly on the street due to acute kidney failure caused by crush syndrome!"

"And the murderer who killed him was none other than his bastard father who was fists and kicks his family!"

He made a conclusion with such indignation.

But Lin Xinyi, who put forward this point, "sang the opposite":

"Don't use such certainty."

"We have to use autopsy to find evidence before we can make a conclusion."

Lin Xinyi's attitude has always been cautious.

Until definitive evidence is found, he will have some guesses, but will also always keep his suspicions open.

Otherwise, this is a purposeful search for evidence, and subjective bias is prone to occur in the investigation.

To put it to the extreme, this is like asking a red neck, who is itself anti-science, to do a scientific experiment to verify the effectiveness of masks

They came to the conclusion that the mask was completely useless and that there was a mind control antenna hidden inside.

"So, let's start dissecting!"

"Let the dead tell us what he died for."

As soon as Lin Xinyi said this, he stood on the right side of the autopsy table and bowed solemnly to the deceased.

Narumi Asai bowed to the deceased with the same seriousness.

He used to be a victim of the police's disregard for life and dereliction of duty, so he can better understand the weight of the word "respect".

Then, the dissection began.

With the professional assistant of Narumi Asai, Lin Shinichi's dissection work went very smoothly.

He first cut open his back and chest, the two areas with the most bruises and swelling:

"Cutting the skin tissue of the back and chest can show massive bleeding in the superficial and deep muscles, loose muscle tissue, and edema."

"Extensive subcutaneous bleeding, which is one of the typical symptoms of crush syndrome."

Necrotic muscle tissue is noticeably pale, brittle, and looks like dead fish meat.

There is a clear demarcation between this and the surrounding musculature.

Looking at the irregular shape of the demarcation, it is even more certain that it is the result of repeated beatings

If it is caused by the compression of a large heavy object, the necrotic muscle tissue will join together and have a more regular shape.

"And..."

Lin Xinyi opened the chest cavity and abdominal cavity with the help of shallow well.

Leaving aside the varying degrees of failure of the other organs, the most important thing to identify as having died of crush syndrome is the condition of the heart, kidneys, and bladder.

"The painstaking work has been extracted, and now it will be sent to the scientific search and research for identification."

"If the blood potassium, magnesium, and myoglobin concentrations are seriously exceeded, it can be proved that crush syndrome caused death."

After a busy time, Lin Xin began to check his kidneys.

Both of the deceased's kidneys were visibly enlarged, and there was a problem at first glance.

Remove it again for histological examination:

"Glomerular vitreous degeneration, partial epithelial cells of the proximal convoluted tubule are degenerated, swollen, necrotic, and shedding, and erythroprotein casts are seen in the distal convoluted tubules and collecting ducts..."

"This is a symptom of kidney failure and is one of the necessary conditions to distinguish crush syndrome."

Lin Xinyi found more conclusive evidence.

On the side of the bladder that Asai Narumi was in charge of examining, the problem was even more obvious:

"The urine is soy sauce..."

"I don't know by identification, but I also know that the concentration of myoglobin in the urine exceeds the standard."

The large amount of myoglobin released after muscle tissue necrosis is one of the main culprits of kidney failure.

Therefore, brown myoglobinuria is strong evidence to identify crush syndrome.

"Mr. Lin."

Narumi Asai breathed a sigh of relief:

"I think I can jump to conclusions, right?"

"The deceased died of sudden death from acute renal failure caused by crush syndrome."

"And the murderer who killed him is undoubtedly Katsu Matsubara, who has already admitted to domestic violence!"

He thought that he could get Lin Xinyi's affirmative answer now.

But Lin Xinyi's answer was:

"Indeed, we have ascertained the cause of death of the deceased."

"Then, let's try to confirm the identity of the murderer."

"Huh?" Asai Narumi was slightly stunned: "Hasn't the identity of the murderer been confirmed?" ”

"Who else but the violent Matsubara Katsu?"

"He is indeed a murderer."

"Without his violence three days ago, the deceased's crush syndrome could not have been so severe."

Lin Xinyi paused slightly, and his tone became a little subtle:

"But, who said..."

"There can only be one murderer?"
