"Louder, I can't hear you."

"Wait, what's going on... I feel like my ears are buzzing."

After discovering that there was something obviously wrong with his body, he who had been in a daze all night finally woke up completely.

Tsuji Hiroki couldn't help covering his ears and eyes in shock:

"And the eyes...the eyes also feel a lot blurred."

"..." Lin Xinyi was silent for a while.

"Tinnitus, hearing loss, as a result of increased intracranial pressure that ruptures the eardrum."

"Impaired vision is also the reason."

Then, he tried to reach Tsuji Hiroki's chest, and pressed his chest lightly: "Does it hurt?"

"Yes, a little..." Tsuji Hiroki frowned and replied, "And I feel that my lungs are also hurting, and it is difficult to breathe."

"Sure enough, it's the same as I thought..."

"Such a severe facial cyanosis, even some subcutaneous congestion on the shoulders and upper chest."

Lin Xinyi paused for a moment, and said a shocking conclusion:

"This is not a mechanical suffocation caused by a simple accident..."

"It's traumatic suffocation caused by external violent compression of the chest!"

"Hey?!"

The victim himself was still confused, but Mao Lilan was shocked:

"Mr. Hayashi, you mean... Mr. Hiroki Tsuji's chest was violently squeezed?"

"But, Mr. Tsuji's chest has no trace of being squeezed by external force at all!"

"It's enough to use soft objects such as pillows and quilts."

"In this way, no obvious indentation will be left on the victim's body surface, and it is difficult to find problems only by physical examination."

Lin Xinyi explained methodically:

"And this time the 'squeeze murder method' is different from the previous case of the Songyuan family."

"Ms. Matsubara wanted to use prolonged heavy compression to cause extensive muscle necrosis in the victim, thereby inducing crush syndrome and causing the victim to die suddenly after a period of time."

"But this time, the murderer suppressed the movement of the thorax by squeezing the chest, making the victim unable to breathe, and finally suffocated to death in a short period of time."

"Because the force was not applied for a long time, the degree of muscle necrosis was not large."

"With padded cushioning, it protects the skin on the body surface."

"Therefore, Mr. Tsuji could not see any external damage to his chest, nor could he see obvious subcutaneous hemorrhage."

He carefully analyzed the murderer's method of killing, and then said with emotion:

"In this way, it is difficult to distinguish the signs of suffocation from 'accidental suffocation' just by checking the body surface."

"In the absence of an autopsy, it is normal to make mistakes in judgment."

People are not dead yet, so naturally there is no way to do an autopsy.

So we can only wait for Tsuji Hiroki to wake up, and diagnose his condition according to the method of a doctor who treats a living person.

"Then, Mr. Lin..."

Although Mao Lilan lacked professional knowledge, she still responded quickly:

"You just judged from Mr. Tsuji's visual and hearing impairment just now that his suffocation was actually caused by a violent squeeze on his chest?"

"That's right." Lin Xin nodded.

"Different from the relatively 'mild' form of suffocation by being suffocated by a pillow..."

"When the chest is severely squeezed, when the chest and upper abdomen are violently squeezed, the injured person's glottis is suddenly closed, and the air in the trachea and lungs cannot escape."

"Both factors work together to cause a sudden increase in intrathoracic pressure."

"The increased pressure on the right heart and the superior vena cava system, which lacks venous valves, regurgitates venous blood into the upper chest, neck, and face, leading to what we see as a cyanotic swelling that can spread from the cheeks to the upper chest. "

"Of course, based on this alone, it is difficult to distinguish it from the severe suffocation symptoms that may occur during suffocation."

"but…"

He paused slightly, and his tone quietly increased:

"When the intrathoracic pressure increases, the pressure will also be transmitted to the intracranial through the blood in the blood vessels, resulting in a significant increase in intracranial pressure."

"The cerebrospinal fluid is forced through the lymphatic space around the central blood vessel to reach the lymphatic space of the retinal blood vessels, causing blood vessel rupture and lymphatic overflow into the retinal tissue, and white exudates and hemorrhages appear in the fundus."

"This is reflected clinically..."

"You have vision loss immediately after the injury, visual field damage."

"And also because of increased intracranial pressure, the eardrum may be damaged, leading to tinnitus and hearing loss."

"So, judging from Mr. Tsuji's current vision and hearing loss..."

With a firm gaze, Lin Xin made a firm conclusion:

"Mr. Tsuji's chest must have been continuously squeezed by an external force!"

"And now he feels pain in his lungs and difficulty breathing. It is likely that the organ was damaged during the compression process, resulting in the lung contusion that often occurs in traumatic asphyxia."

"Get the doctor in that direction to do a chest X-ray and CT for Mr. Tsuji, and it should be easy to diagnose the results.".

This place happens to be a hospital, and if a doctor from the hospital comes over for an examination, he will definitely get a more professional and authoritative conclusion than him.

So, it is now almost certain that...

What Tsuji Hiroki encountered yesterday was definitely more than just an accident.

"That is to say..."

"The murderer took advantage of Mr. Tsuji's drunkenness, covered his chest with pillows and quilts, and continued to squeeze his chest hard?"

"But...how does that explain the pillow marks on his face, and my dad's testimony?"

Mao Lilan asked a question in a timely manner: "Mr. Tsuji Hiroki did lie on the pillow when he was drunk, and he was bored for a while."

"Otherwise, he wouldn't have the pillow mark on his face."

"Yes, Mr. Tsuji did suffocate himself in the pillow."

Lin Xinyi smiled:

"But it doesn't contradict the murderer's violence against him later, does it?"

Tsuji Hiroki did fall headfirst on the pillow after being drunk, but it was not necessarily the reason why he fell into such a serious suffocation state.

Because the human body feels uncomfortable in sleep, it will turn over by itself.

Although the muscles of a drunk person are weak, it is easy to fail to turn over.

But people and their physiques cannot be generalized.

It is indeed extremely dangerous to sleep on the stomach after being drunk, but not everyone will be unable to turn over and suffocate themselves to death.

In particular, Tsuji Hiroki himself is still a professional athlete with good physical fitness.

He might lie drunk for a while, feel bored and uncomfortable, and then turn over by himself in a daze.

"Mr. Tsuji was indeed suffocated by the pillow for a while, but he was not so suffocated that he was suffocated."

"However, this may have given the killer inspiration."

Lin Xinyi told his own reconstruction of the incident:

"Seeing Mr. Tsuji almost unconsciously suffocating himself, the murderer on the side may suddenly think of using this opportunity to secretly assassinate the killer."

"Suffocation caused by squeezing the chest, disguised as suffocation caused by suffocation on the pillow after being drunk."

"And the facial marks that Mr. Tsuji bored himself out before can become the true but false evidence."

"By killing people in this way, it is very likely that the police will judge the victim's death as a pure drunken accident."

"However, he failed."

"On the one hand, it's because Mr. Tsuji's physical fitness is too good."

As above, people and their physiques cannot be generalized.

In the case of a newborn baby, the weight of a fist can kill.

So occasionally in reality, the kind of tragedy that parents put their arms on the child's chest unconsciously while sleeping, resulting in the baby's suffocation and death.

For an average adult, a weight of 40-50 kg on the chest and abdomen may cause death by suffocation.

But this number can be doubled for the physically fit, reaching an exaggerated 80-100kg.

Tsuji Hiroki is a professional athlete, and his body is not generally strong.

Even if the murderer puts all his strength on it, he won't be able to kill him for a while.

Of course, after a long time, Tsuji Hiroki will definitely lead to death.

but…

"But at that moment, Miss Morley, you happened to be upstairs looking for Papa."

"Hearing your footsteps going up the stairs, the murderer must not dare to continue to commit murder."

Lin Xinyi said with some amusement:

"So, the murderer put Mr. Tsuji, who had been severely suffocated, back to the original lying position, trying to cover up his traces of violence and forge a simple accident scene."

"And he didn't have time to leave before you entered the bedroom, so he could only pretend to be drunk and lie on that bed."

"Then, the murderer can only be..."

At that time, apart from Tsuji Hiroki, there were only Sawaki Hiroki and Mori Kogoro in the room.

And Mao Lilan personally verified that her father slept like a dead pig at that time.

Obviously, the murderer can only be...

"Sawaki is fair!"
