According to Lin Xinyi's instructions, Mao Lilan quietly greeted the two police officers who were on duty outside the ward, and asked them to keep an eye on Zemu Fair.

Sawaki didn't seem to be aware of everyone's wariness of him, and he behaved very naturally and calmly.

When Mao Lilan walked in front of him, he naturally took the initiative to say hello:

"Xiaolan, it's the forest manager of the Metropolitan Police Department who is in the ward now, right?"

"Is he here because of the accident that happened to Mr. Tsuji yesterday, and what else is wrong?"

"No, I don't." Mao Lilan shook his head, and replied with a false answer: "Mr. Lin has checked it, and he also said that Mr. Tsuji should have been suffocated by an accident. ”

"That's right..."Sawaki's smile was still calm.

And after a casual question of understatement, he got up from his seat again:

"I'll go to the bathroom first."

"Since Mr. Tsuji is fine, this is another simple accident, and I should leave later."

Sawaki said to himself while taking a calm and steady step and slowly walked towards the bathroom.

"Hmm... Good. Maolilan stopped talking.

At present, there is a high probability that this matter was an accident, and she couldn't find a reason to keep Sawaki Fair and Strong.

Moreover, now this guy is going to the toilet, and she is not easy to follow as a girl.

Mao Lilan had no choice but to give the two police officers a sneaky look and tell them to pay attention to the monitoring and tracking of Sawaki Fair.

In this way, Sawaki walked to the bathroom with a natural expression.

The two police officers also pretended to be "inspired", clinging to him and teaming up to go to the toilet.

And after they left...

"Mr. Tsuji, Mr. Tsuji, are you awake?"

Lin Xinyi's tentative cry came from the ward.

"Mr. Tsuji woke up?"

Mao Lilan was slightly stunned, and then hurried back to the ward.

She was very curious in her heart, what Lin Xinyi just said, what the "remaining possibility" was.

"Hmm... My chest is so tight..."

Hiroki Tsuji's unconscious murmur rang out in the hospital room.

He sat up from the sickbed in a daze, squinted his eyes tightly like a dazzled old man, and looked at Lin Xinyi who was sitting in front of the sickbed:

"You... You are... Yesterday, the forest manager? ”

"Why are you here?"

"Wait... What really happened last night? ”

"How can I only remember that Mr. Kogoro secretly kissed me in bed..."

Hiroki Tsuji had apparently not fully recovered from his hangover and coma, and it was a bit difficult to talk to him.

But without a conversation, Lin Xinyi had already discovered that something was wrong.

He carefully looked at Hiroki Tsuji's bruised and swollen eyelids, and watched him squint at the pair of panda eyes that were quite serious, and struggled to make an expression of "subway old man's mobile phone .jpg".

And looking through the eyes that were slitted together, it was not difficult to see the scarlet bloodshot in Hiroki Tsuji's eyes that had not faded until now.

"Mr. Tsuji, are you squinting at me like this because..."

Lin Xinyi's tone became extremely solemn:

"You can't see clearly?"

"Huh?" Hiroki Tsuji was slightly stunned: "Manager Lin, what did you say?" ”

"Be louder, I can't hear you."

"Wait, what's going on... It felt like it was buzzing in my ears. ”

After discovering that there was something obviously wrong with his body, he finally woke up completely after being confused all night.

Hiroki Tsuji couldn't help but cover his ears and eyes with a shocked look:

"And the eyes... My eyes also feel a lot blurry. ”

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

"Tinnitus, hearing loss, which is a consequence of increased intracranial pressure that causes the eardrum to rupture."

"This is also the reason for the impaired vision."

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

"Yes, a little," Hiroki Tsuji replied with a frown, "and I feel like my lungs are also hurting, and I have some difficulty breathing." ”

"Sure enough, just as I thought..."

"Such severe cyanosis of the face, even the shoulders and upper chest have dotted subcutaneous bruises."

Lin Xinyi paused slightly, and said a terrifying conclusion:

"It's not mechanical asphyxiation caused by a simple accident...."

"It's traumatic suffocation caused by external violence in the chest!"

"Huh?!"

The victim himself was still in the clouds, and Mao Lilan was already shocked:

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

"However, Mr. Tsuji's chest has no signs of being squeezed by external forces at all!"

"Just use a soft object like a pillow or quilt."

"In this way, there will be no obvious indentations on the victim's body surface, and it is difficult to detect the problem just by examining the body surface."

Lin Xinyi explained in an orderly manner:

"And this time's 'squeezing and killing method' is different from the previous case of the Matsubara family."

"Mrs. Matsubara wanted to use the long-term heavy squeeze to cause a large area of necrosis of the victim's muscles, so as to induce crush syndrome, so that the victim died suddenly after a period of time."

"But this time, the murderer inhibited the movement of the chest by squeezing the chest, so that the victim could not breathe, and finally suffocated to death in a short time."

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

"Plus, it's cushioned to protect the skin on the surface."

"So Mr. Tsuji couldn't see the external damage on his chest, and he couldn't see any obvious subcutaneous bleeding."

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

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

"It's normal to make mistakes in judgment without an autopsy."

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

So I had to wait for Hiroki Tsuji to come to his senses and diagnose his condition according to the method of the doctor who treated the living.

"Then, Mr. Lin..."

Despite its lack of expertise, Māoriland was quick to respond:

"You just judged from the sight and hearing impairment that Mr. Tsuji showed just now, and his suffocation was actually due to violent squeezing of his chest?"

"That's right." Lin Xin nodded.

"It's different from the relatively 'gentle' way of suffocating with a pillow..."

"When the chest is severely compressed, when the chest and upper abdomen are violently compressed, the victim's glottis suddenly closes, and the air in the trachea and lungs cannot escape."

"The combination of these two factors causes a sudden increase in intrathoracic pressure."

"The increased pressure compresses the right heart and the superior vena cava system, which lacks a venous valve, causing venous blood to flow back up to the upper chest, neck, and face, resulting in the cyanosis that we see that can spread from the cheeks to the upper chest."

"Of course, this alone makes it difficult to distinguish it from the severe suffocation symptoms that can occur when suffocating."

"But..."

He paused slightly, and his tone quietly increased:

"When intrathoracic pressure is high, the pressure can also be transmitted to the skull through the blood in the blood vessels, resulting in a significant increase in intracranial pressure."

"Cerebrospinal fluid is forced through the lymphatic space around the central blood vessels to reach the lymphatic space of the retinal blood vessels, causing blood vessel rupture and lymphatic overflow into the human retinal tissue, resulting in white exudate and hemorrhage in the fundus."

"This is reflected in the clinic..."

"There will be symptoms of vision loss and visual impairment immediately after the injury."

"And because of the increase in intracranial pressure, the eardrum may be damaged, resulting in tinnitus and hearing attenuation."

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

Lin Xinyi's eyes firmly came to a conclusion:

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

"He now feels pain in his lungs, difficulty breathing, and most likely organ damage during compression, resulting in the lung contusion that often occurs in traumatic asphyxia."

"Having a doctor do a chest X-ray and CT scan for Mr. Tsuji in this direction should make it easy to diagnose the results.".

This happens to be the hospital, and if the doctor from the hospital comes to check it, he will definitely be able to come to a more professional and authoritative conclusion than him.

So, now it's pretty much certain that...

What happened to Hiroki Tsuji yesterday was definitely not just an accident.

"That is to say..."

"The murderer took advantage of Mr. Tsuji's drunkenness, put a pillow and quilt on him, and continued to squeeze his chest hard?"

"But... How does this explain the pillow marks on his face, as well as my dad's testimony? ”

Mao Lilan asked a question at the right time: "Mr. Hiroki Tsuji did get drunk and lay on the pillow himself, and he was bored for a while. ”

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

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

Lin Xin smiled:

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

Hiroki Tsuji did fall on the pillow after being drunk, but it didn't necessarily fall into such a serious state of suffocation because of this.

Because the human body feels uncomfortable in sleep, it will turn over on its own.

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

But people and human constitutions cannot be generalized.

It is indeed extremely dangerous to fall asleep on your stomach after being drunk, but not everyone will be able to roll over and suffocate themselves to death.

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

He may have been drunk for a while, feeling uncomfortable, so he turned over himself in a daze.

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

"However, it may have inspired the murderer."

Lin Xinyi told the story of the case that he had restored:

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

"The suffocation caused by squeezing the chest is disguised as the suffocation caused by being drunk and stuffed on the pillow."

"And the marks on Mr. Tsuji's own face that he had stuffed himself before can be evidence of the truth but the error."

"If you kill someone in this way, it is very likely that the police will judge the victim's death as a simple drunken accident."

"But he didn't make it."

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

Ibid., people and human constitutions cannot be generalized.

In the case of a newborn baby, the weight of a fist can lead to death.

So in reality, there are occasional tragedies where parents unconsciously put their arms on their children's chests while sleeping, resulting in the death of suffocation of babies.

In the average adult, a weight of 40~50kg in the chest and abdomen may lead to suffocation.

But this figure can be doubled for the able-bodied, reaching an exaggerated 80~100kg.

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

Even if the murderer pressed the strength of his whole body, he would not be able to crush him for a while.

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

But...

"But at that time, Miss Maori, you happened to come upstairs to find your father."

"Hearing your footsteps going up the stairs, that murderer will definitely not dare to continue the murder."

Lin Xinyi said with some amusement:

"Therefore, the murderer put Mr. Tsuji, who was already seriously suffocated, back to the position where he was lying on his stomach, trying to cover up his traces of violence and fake a simple accident scene."

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

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

At that time, in addition to Hiroki Tsuji, there were only Fair Sawaki and Kogoro Mori in the room.

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

Obviously, this murderer can only be...

"Sawaki is fair!"
