"Is there more than one murderer?"

"You mean, there were two people who committed violence against the deceased 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're still lacking a little experience."

Lin Xin smiled, then pointed to the upper arms on both sides of the corpse close to his shoulder, and said carefully:

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

"I noticed... Any questions? ”

Asai Narumi's tone was very puzzled:

The deceased had extensive bruises on both upper arms.

To the poor deceased, who was swollen and purple almost all over, and did not have a good piece of meat, these two bruises looked nothing at all.

Even, it seems a little lighter.

"It's because the injury is too light that it looks suspicious."

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

"Matsubara Katsu has a lot of strength and likes to beat people with fists, kicks and sticks."

"So the wounds he made were often accompanied by severe epidermal peeling injuries."

"And the skin on the big arms on either side of the deceased..."

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

"This..."Narumi Asai had already figured out something was wrong: "yes... If the bruise had been violently beaten, the surface of the skin would not have been so intact! ”

And Lin Xinyi continued:

"What's even stranger is that compared to the bar damage caused by sticks, the block damage caused by punches and kicks..."

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

"Is this a hit?"

"If you want to be beaten, you can only be hit on one side of the arm, and it can't be evenly hit on all sides, right?"

"Look at it again..."

Lin Xinyi raised the deceased's hand and let Asai Narumi see the deceased's fingertips clearly:

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

"There are still some red and black spots under his fingernails."

"Asai, do you know why?"

Asai Narumi pondered.

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

"Damn... So that's it..."

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

"But the real cause should be the lack of blood supply to the distal hand, which caused the necrosis of the fingertip muscles, so there is slight swelling."

"The cause of the lack of blood supply to the distal hand is..."

"It was because the deceased's upper arm 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 is different from the injuries of other parts of the deceased's body. ”

"The bruises on his large arms on either side were not blunt force blows, but..."

"It's a crush injury!" Narumi Asai blurted out: "This is a large bruise that can only be formed when the arm is squeezed by a heavy object for a long time. ”

"And this weight is still very soft, otherwise it would not have been possible to not even cause a little peeling of the epidermis."

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

"So..."

After being inspired by Lin Shinichi, Asai Narumi was already able to draw inferences from each other:

"So, it could be someone pressing the deceased's arm with a soft object like a quilt, pillow, or something."

"Then kneel down and press it onto the quilt and pillow, and apply heavy pressure evenly downward."

"That's right." Lin Xinyi said: "This is a very terrible method of killing. ”

"Because the weight is soft enough, the indentation is not noticeable after the sustained weight is applied."

"And the deceased, who was covered in injuries and pain, may not even notice the slight bruises on his arms that are not broken."

"When the muscles of the arm that have been squeezed for a long time are necrotic and congested, and the bruise worsens to the point that it is swollen and purple, and cannot be ignored..."

"His life is coming to an end."

Lin Xinyi sighed so embarrassedly.

But Asai Narumi was relieved from his excitement.

He pondered Lin Xinyi's statement carefully, and immediately found that it was wrong:

"Wait, the bruises caused by this method are really not obvious at first."

"However, for a long time it was pressed on the arm of the deceased..."

"The fact itself couldn't be more obvious, right?"

"Wouldn't it have been discovered that something so heavy had been pressed on the deceased's body for so long?"

"It depends on the results."

Lin Xinyi replied unhurriedly:

"Under normal circumstances, it is impossible not to notice that your arm is pressed by a heavy object."

"But if the deceased was in a drunken state at the time, of course, the more likely guess is..."

"The deceased drank sleeping pills, so he was unconscious and let the murderer do it."

"So as soon as I got my heart's work, I immediately sent it to the scientific search for identification."

"In addition to identifying blood potassium, myoglobin concentrations and other indicators that can prove crush syndrome, I also want them to help see if there are any sleeping pills in the blood of the deceased."

"If there is, then our suspicions can be confirmed to a certain extent."

"Hmm..."

Asai Narumi followed this line of thought and thought about it carefully:

"Indeed, if all of this can be confirmed, I'm afraid that Matsubara is not the only murderer."

"Because he would not have abused the dead by squeezing his arm with a heavy object"

"If it's abuse, there's no need for him to cover it up with a soft object."

"And Matsubara's purpose is just to use violence to vent his emotions, and for him, the use of fists, feet, and sticks is more direct and refreshing."

"So..."Narumi Asai raised his head and looked at Lin Xinyi: "Mr. Lin, who will this second murderer be?" ”

"Alas..."Lin Xinyi sighed deeply.

Speaking of which, even though he didn't know the dead Mr. Kenichi Matsubara, he still felt sorry for him.

"Let's say our previous conjectures aren't biased."

"The one who can enter the deceased's room while he is asleep and put heavy pressure on his arm for a long time..."

"Who else but the family who lives with him?"

"Family..."

Speaking of this word, Asai Narumi's expression became a little complicated.

For him, who has suffered drastic changes since he was a child, his family will always be his most beautiful and precious thing.

But now, in the body of this unfortunate Mr. Kenichi Matsubara, the "family" seems to have become the most terrible demon.

"How many people are in the deceased's family?"

Asai asked in a low voice.

Somehow, he was a little nervous about the issue.

"I asked beforehand, and there were only three people in the deceased's family."

"The only people who live with him are the Matsubara couple as parents."

Lin Xinyi's voice was full of sighs.

"There are only three people..."

Asai Narumi was slightly stunned:

The second murderer is most likely the family who lived with the deceased, but only his parents lived with him.

That being the case, in addition to Katsu Matsubara, who inflicted domestic violence on him.

The second murderer who squeezed his arm with a heavy object could only be...

"Mrs. Matsubara?!"

Asai Narumi's expression was extremely shocked.

His mind couldn't help but flash the sad look of the lady Matsubara crying in the office.

Could it really be her?

Narumi Asai couldn't believe it:

"How could Madame Matsubara know how to aggravate the deceased's injuries by squeezing such a heavy object?"

"It's only been two years since the academic research on crush syndrome began, and this should only be understood by people with a certain amount of medical knowledge, right?"

"Madame Matsubara's profession is not a doctor!"

"Lady Matsubara is indeed not a doctor." Lin Xinyi replied, "But haven't you heard her say it before?" ”

"She was once subjected to domestic violence by Katsu Matsubara, and was hospitalized twice when she was serious."

"If she had been ill for a long time, and if she had experienced this symptom herself, Mrs. Matsubara would naturally have some understanding of crush syndrome."

"This..."Narumi Asai was speechless.

But he still instinctively didn't want to believe that the murderer would be the poor Matsubara lady:

"Mrs. Matsubara is obviously also a victim of domestic violence, why did she do such a cruel thing to the deceased?"

"And... And that's her own son? ”

"Because it's most likely not her own son."

"The registered age of the deceased is already 24 years old, and Mrs. Matsubara doesn't look like she can have a 24-year-old son."

Mrs. Matsubara looked much younger than Katsu Matsubara.

Although Fei Mi, Yukiko and Belmode have proven with facts that the old aunts in this world have a life-long shelf life.

So theoretically, Mrs. Matsubara may just be just looking young.

But Lin Xinyi was still willing to believe his guess.

After all, tigers don't eat children, and he can't imagine that a woman would murder his own son.

"If Mrs. Matsubara is a stepmother and the deceased is not his own son, everything can be explained."

"Because of Matsubara's domestic violence, she has a hatred for the Matsubara family."

"So she wants to kill Kenichi Matsubara."

"In this way, Matsubara will not only lose his only offspring, but he will also have to be charged with manslaughter."

"After all, he did brutally beat the deceased."

"As long as we police are involved in the investigation, if the autopsy is not careful enough, it is easy to assume that the death of the deceased is entirely due to Katsu Matsubara's domestic violence."

"But in fact, in the course of Kenichi Matsubara's death..."

"The crush injury caused by the second murderer also played an extremely important role."

He is accustomed to seeing the darkness of society, and has never been afraid to speculate on the psychology of suspects with the greatest malice.

But such a callous speculation is still unbearable:

"If only everything could work out the way the murderer thinks."

"She will be able to say goodbye to the Songwon family forever as a pure victim."

"In her opinion, maybe this is a perfect revenge, right?"

Hearing this, Asai Narumi was silent for a long time.

"Is this really the case..."

"In this case, it would be too sad for Mr. Kenichi Matsubara to be born in such a family."

Compared to Kenichi Matsubara, he even felt that his experience was happy.

"Alas...."Lin Xinyi also sighed:

"Before the autopsy began, I asked for a search lesson in advance to investigate the situation of the Matsubara family."

"And the last voice of the deceased has been conveyed."

"Let's go, it's time to talk to the Matsubara couple."

Lin Xinyi's voice became extremely solemn:

"We can't change his tragedy, but at least... Don't let justice be absent. ”
