He first cut open the back, the chest, the two most bruised and swollen areas:

"The skin tissue of the back and chest was cut to reveal extensive bleeding in the superficial and deep muscles, loose muscle tissue, and edema."

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

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

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

And looking at the irregular boundary shape, it is more certain that this is caused by repeated beatings

If it is caused by the extrusion of a large heavy object, the necrotic muscle tissue will be connected into one piece and the shape will be more regular.

"and also…"

With the help of Asai, Lin Xinyi opened the chest cavity and abdominal cavity.

Leaving aside the varying degrees of failure of other organs, the condition of the heart, kidney, and bladder is the most important thing to determine whether the deceased died of crush syndrome.

"The hard work has been extracted, and now it will be sent to Kesouyan for identification."

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

After some busy work, Lin Xinyi started to check his kidneys.

The two kidneys of the deceased were obviously enlarged, and there was a problem at first glance.

Take it out for histological examination:

"Glomerular hyaline degeneration, degeneration, swelling, necrosis, and shedding of epithelial cells in the proximal convoluted tubule, and red stained protein casts in the distal convoluted tubule and collecting duct..."

"It's a symptom of kidney failure, and it's one of the must-haves in identifying crush syndrome."

Lin Xinyi found more conclusive evidence.

As for the bladder inspected by Shigemi Asai, the problem is even more obvious:

"The urine is the color of soy sauce..."

"I can't help but know that the concentration of myoglobin in the urine exceeds the standard."

A large amount of myoglobin released after muscle tissue necrosis is one of the culprits leading to kidney failure.

Therefore, brown myoglobinuria is strong evidence for identifying crush syndrome.

"Mr. Lin."

Naruto Asai breathed a sigh of relief:

"Should we be able to draw conclusions now?"

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

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

He thought that he could get a positive answer from Lin Xinyi now.

But Lin Xinyi's answer was:

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

"Then, we can try to confirm the identity of the murderer next."

"Hey?" Asai Chengshi was slightly taken aback: "Hasn't the identity of the murderer been confirmed?"

"Besides the violent Matsubara Katsura, who else?"

"He is indeed a murderer."

"Without his violence three days ago, the crush syndrome of the deceased 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?"

Chapter 226 The House of Tragedy

"Murderer, more than one murderer?"

"You mean, there were two people who were violent to the dead man while he was alive?"

"Wait... can this also be seen from the corpse?"

Hearing such bizarre remarks, Asai Narumi's expression was a little stunned.

"Haha, you still lack a little experience."

Lin Xin smiled, pointed to the upper arms on both sides of the corpse near the shoulders, and said in detail:

"Asai, did you notice the bruises on the upper arms on both sides of the deceased when you checked the autopsy?"

"I noticed... Is there a problem?"

Shigemi Asai's tone was very puzzled:

The left and right upper arms of the deceased had large bruises.

These two bruises looked inconspicuous to the poor dead man who was almost swollen and purple, without a good piece of flesh.

Even, it seems a little lighter.

"It's because the injury is so minor that it looks suspicious."

Lin Xinyi pointed to the dead man's swollen and purple arm:

"Matsubara Katsura is quite strong, and he likes to beat people with fists, kicks and sticks."

"So the wounds he made are often accompanied by severe skin peeling damage."

"And the skin on both sides of the deceased's arms..."

"You see, although there is visible subcutaneous bleeding, the surface of the skin is still intact."

"This..." Asai Chengmi had already figured out something was wrong: "That's right... If this bruise was caused by a violent beating, the surface of the skin could not be so intact!"

And Lin Xinyi continued:

"What's even more strange is that compared with the strip damage caused by sticks and the block damage caused by fists..."

"The bruises on the deceased's upper arm were very large, covering almost half of the upper arm from front to back."

"Is this possible to fight?"

"If you want to be beaten, you can only be hit on one side of the arm. It is impossible to be hit evenly on all sides?"

"Look here again..."

Lin Xinyi raised the dead man's hand, allowing Asai Narumi to see clearly the dead man's fingertips:

"The fingertips of the deceased also had less obvious cyanotic swelling."

"Under his nails, there are still some red and black spots."

"Asai, do you know why?"

Asai Chengshi thought for a while.

And the knowledge reserves of medical students made him understand quickly:

"Damn it...so that's how it is..."

"When I did the autopsy, I thought those fingers were bruises from abuse."

"But the real reason should be that the blood supply to the distal part of the hand is insufficient, resulting in necrosis of the fingertip muscles, so there is a slight swelling."

"And the reason for the lack of blood supply to the distal hand is..."

"It's because the upper arm of the deceased was squeezed by a heavy object for a long time, resulting in poor blood circulation!"

"That's right!" Lin Xinyi nodded with satisfaction: "So, it's different from the injuries on other parts of the deceased's body."

"The bruises on both of his upper arms were not blunt force trauma, but..."

"It's a crush injury!" Asai Shiromi blurted out, "This is a large area of ​​bruises formed when the arm is squeezed by a heavy object for a long time."

"And this heavy object is still very soft, otherwise it would not have caused even a little peeling of the skin."

"But in life, it's hard to find something that is both soft enough and heavy enough."

"so…"

After being inspired by Hayashi Shinichi, Asai Chengshi has been able to draw inferences from one instance and put forward guesses:

"So, it's possible that someone was pressing down on the deceased's arm with a soft object like a quilt, a pillow."

"Then kneel down and press down on the quilt and pillow, applying heavy pressure evenly down."

"That's right." Lin Xinyi said, "This is a terrible method of killing people."

"Because the weight is soft enough, the indentation is very indistinct after applying constant heavy pressure."

"And the deceased may not have noticed the extra minor bruises on his arms when he was covered in injuries and pain."

"Wait until the arm muscles that have been squeezed for a long time are necrotic and congested, and the bruise has deteriorated to the point where it is too swollen and purple to ignore..."

"His life has come to an end."

Lin Xinyi sighed so sadly.

But Asai Chengshi was relieved from the excitement.

He thought about Lin Xinyi's statement carefully, and immediately realized that it was wrong:

"Wait, the bruises from this method are really not noticeable at first."

"However, being pressed on the dead man's arm for a long time..."

"Isn't that too obvious in itself?"

"There is such a heavy thing on the dead body, and it has been pressed for such a long time, won't it be discovered?"

"It depends on the appraisal results."
