"The murderer is also likely to be left-handed."

"Because according to the on-site investigation records? The blood ejected from the carotid artery of the deceased even splashed unimpededly onto the TV wall 1.8 meters away."

"And the distribution is even and the area is relatively wide. Blood droplets are sprayed from the ceiling to the floor."

"This shows that the deceased should have been in a standing posture at the time, and when there was no obstacle in front of him, the murderer held his head with one hand to support his body from behind, and cut off his neck with the other."

"And if you kill someone in such a posture..."

Asai Chengmi simulated a gesture of wiping someone's neck from behind:

"Hold the knife with the right hand, and the knife edge left on the neck of the deceased should be from left to right."

"And the incisions on the neck of the deceased were from right to left."

"This shows that the murderer is likely to be left-handed. He held a knife in his left hand and cut the neck of the deceased from right to left from behind."

"I see." The expressions of Sato, Shiratori, and Takagi became more solemn:

Oda Kiritoshi also had a motive for committing the crime.

And he happens to be left-handed.

The minister's son and the criminal's characteristics are becoming more and more consistent, which is what all the police don't want to see.

"However, it's not necessarily true..."

Asai Narumi thought about it, and added:

"Because the murder weapon used by the murderer is a scalpel."

"With the sharpness of a scalpel, it doesn't take much effort, just a little stroke can cut through the skin and subcutaneous tissue, and cut off the trachea and carotid artery."

"So, if I were to kill someone with a scalpel..."

"I may choose to use my more dominant right hand to hold the head of the deceased, so as to prevent the other party from struggling and resisting to the greatest extent."

"Then hold the knife with your left hand—it doesn't matter if you don't use your left hand, anyway, you can kill the dead with just one swipe."

Asai Chengshi analyzed the movements and gestures of killing people with a scalpel well.

It looked as if he had practiced this way in private.

"Well…"

"In this case, the possibility of the murderer being right-handed is not small."

"Then our future investigations will still focus on left-handed people, and at the same time, we can't ignore the suspects who are right-handed."

"In short, I'd rather work hard to cast the net wider than let the fish escape."

Lin Xinyi followed the train of thought of Naruto Asai to sum up, but his expression couldn't help being a little weird:

Naomi Asai is a doctor.

When he was planning his revenge plan before, maybe he really thought about how to use his best scalpel to kill people?

"Wait...a scalpel?"

Lin Xinyi suddenly thought of something:

"Did the murderer bring the scalpel himself, or did he take it from the crime scene, that is, the deceased's home?"

"Of course it was taken from the deceased's house..."

Miwako Sato quickly replied:

"The deceased Dr. Renye had an instrument box for storing various surgical instruments in his home. A scalpel handle was missing in it, and there was also a newly torn wrapping paper for a disposable surgical blade."

"Because the murder weapon was originally taken from the deceased's home, and it was a scalpel that the deceased was good at using during his lifetime, we judged that he committed suicide at that time."

The deceased Ninoho was an expert in heart surgery.

Like Lin Xinyi, he is a doctor who relies on a scalpel for his living.

Some of these doctors would keep a set of surgical instruments at home, and usually use pigskin, pig heart, grapes and other things to simulate the human body to practice cutting and suturing techniques.

So it's not unusual to find surgical instruments in his home.

It is normal for the murderer to think of the identity of Dr. Ren Yebao, and deliberately go to kill with a scalpel and pretend to commit suicide.

"I understand…"

Lin Xin nodded his head, but his brows were still furrowed.

He also stopped discussing with his subordinates, but picked up the stack of case materials and looked through them carefully.

As he expected, the police officers from the Forensics Division who were involved in handling the case at that time were not good at anything else, but they were excellent at taking pictures.

They were not afraid of wasting film, and took pictures of the crime scene inside and out.

The murder weapon, the surgical instrument box from which the murder weapon was used, and even the original scene around the instrument box were all recorded completely.

This played a huge role in Lin Xinyi's current investigation.

He took a few photos and pondered over them, and suddenly said:

"Oda Kiritoshi also..."

"The murderer should not be him."

Chapter 344 How hard is it to choose a "color number"

Odagiri Toshiya, isn't he the murderer?

Everyone looked at each other in blank dismay:

Obviously all doubts point to this rebellious young minister.

Why is he suddenly unsuspecting?

Is this the conclusion that can be drawn by looking at two photos?

Everyone was puzzled in their hearts, and the active police officer Shiratori couldn't help but cast a subtle look at Lin Xinyi:

Your forest management officer will not say that you want to enforce the law impartially.

In fact, he was sent by the minister to divert the direction of the investigation and to clean up his son, right?

if so…

Then he can only let Shiratori come to the knight of justice, and let Miss Miwako see who is the real upright.

Mr. Shiratori Ren Saburo, the more he thinks about it, the more passionate he feels.

But Lin Xinyi's expression didn't change at all.

He didn't feel guilty at all to excuse the minister, but explained calmly:

"The proof is in these two photographs."

"Just look at it and you'll know."

As he spoke, Lin Xinyi took out two photos from the stack of documents.

One was a close-up of the murder weapon, the bloody scalpel.

One is the overall photo of the surgical instrument box and its surrounding environment.

The surgical instrument box was placed on a wide table not far from the living room, which seemed to be used as a practice console by Dr. Renye.

In the photo, the lid of the box is wide open, and there are all kinds of unnamed knife handles, pliers, and scissors that look similar in shape and are neatly placed inside.

What everyone can see at a glance is that there is one less knife handle placed in the box.

There was also a single-use surgical blade wrapper that had been torn open.

And on the table outside the instrument box, there was also a pair of strangely shaped pliers with long handles.

"Is... what's the problem?"

Everyone looked at each other with blank eyes.

They obviously didn't understand what Lin Xinyi wanted to express.

"Hmm..." Lin Xinyi felt helpless: "Asai, didn't you see anything?"

Asai Chengcheng is now a forensic doctor who deals with scalpels every day, so he should understand.

But his performance is not much better than the three amateurs Sato, Shiratori and Takagi:

"What, what's the matter..."

"These two photos can only show that the murderer took the scalpel from the deceased's home, right?"

"And the location of the surgical instrument box is relatively conspicuous, and you can notice it at a glance—"

"Even Odagiri Toshi, who only had a relationship with the deceased in extortion, could easily find him if he was not familiar with the situation of the deceased's family."

"This does not mean that Oda Kiritoshi is not the murderer!"

Asai Chengmi's thinking is very active.

But his focus and direction of thinking were wrong.

"Okay..." Lin Xinyi sighed softly, "You guys follow me to the anatomy room of the forensics class."

"What are you doing in the autopsy room?"

"Do an experiment."

Lin Xinyi did not directly answer the doubts in everyone's minds, but instead played tricks.

Because he also wanted to pass an experiment to verify whether his guess was correct.

In this way, under the leadership of Lin Xinyi, a group of people came from the search class to the forensics class curiously and puzzledly, and then entered the instrument room of the dissection room.

Lin Xin took them to the instrument cabinet where various surgical instruments were stored, and asked:

"Imagine if you guys were murderers:"

"If you want to cut someone's neck with a knife, which scalpel would you use?"

"Which scalpel to choose?"
