In Conan, people have a brain option system.

Chapter 8 The Missing Smoking Gun

Takuto Nakajima returned to the room that the hospital had lent to the Metropolitan Police Department detectives for their office.

Here, in addition to Conan and Chiba Kazunobu who were already there, there is another one.

It is the high school detective who has been very popular recently - Masumi Sera.

"Hello, Officer Nakajima."

"Ms. Sera, thank you for your help this time."

Takuto Nakajima had heard of Sera Masumi's name a long time ago, but after meeting her face to face this time, he couldn't help but marvel at Sera Masumi's appearance.

A face that is so delicate that it seems a little unreasonably pretty, unique dark green eyes, paired with a light grey baseball cap and a very capable and refreshing short-sleeved shirt outfit, he is simply extremely handsome.

Masumi Sera's personal temperament is far more outstanding than what is published in newspapers and on the Internet.

Takuto Nakajima now finally understands why Masumi Sera, as a JK detective, has such a large number of female fans.

"With such looks and temperament, I'm sure he'll be able to attract a lot of girls wherever he goes. But the one with such a handsome temperament is a high school girl."

Takuto Nakajima complained in his mind.

After greeting Takuto Nakajima, Masumi Sera once again turned his gaze back to the table.

On the table was information collected by the Metropolitan Police Department about Akikawa Sousuke and his mother Akikawa Ryoko.

And the documents and information about this case that are allowed to be made public for detectives to review.

"Nakajima-kun, what's going on?"

At this time, Chiba Heshen opened his mouth and asked Nakajima Takuto.

"Not bad. He was wary of me at first, but now he has basically gained my trust."

"Just like what Inspector Toda said, Akikawa actually has a strong desire to communicate with other people."

"I think after we go back and give him some advice, he should be willing to surrender himself."

Hearing this, Sera Masumi suddenly raised his head and looked fiercely at Nakajima Takuto.

"Excuse me, Officer Nakajima, you are not trying to induce a confession, are you?"

"No, how could we possibly do such a thing?!"

Takuto Nakajima was startled by the sudden sharp gaze from Masumi Sera and quickly responded.

"Then I'm really sorry."

When Sera Masumi heard him say this, he slowly withdrew his gaze and turned his eyes back to the table.

Just now, Takuto Nakajima was completely overwhelmed by Sera Masumi's momentum. Looking back now, Takuto Nakajima feels a little ashamed.

Perhaps because he felt guilty for having the correct answer guessed, Nakajima Takuto did not hold it against Sera Masumi's rude behavior just now.

Takuto Nakajima couldn't help but sigh in his heart once again, "He's really worthy of being a detective, he's so sharp."

If outsiders really knew what they had done, the Metropolitan Police Department would probably be pushed to the forefront of public opinion again.

Nakajima Takuto was still confused about some of the things Conan said last night. Now that Sera Masumi happened to be here, he asked:
"Ms. Sera, I want to ask, how did you determine that Akikawa Sosuke's dagger attack occurred after the car accident?"

"Through the marks of strangulation."

As Sera Masumi said this, he took out a photo. It was a photo of the deceased Akikawa Ryoko that was taken yesterday by a detective from the Metropolitan Police Department.

"You can see that there is a 5-centimeter-thick mark from the right trapezius muscle of the deceased diagonally downward, which is obviously from the car's seat belt."

Most of the car drivers' seats in Japan are on the right side, so the seat belt is tied from the right shoulder to the lower left, which is consistent with the position of the strangulation mark. "Then shouldn't this strangulation mark be left in the car accident? Because the car was violently unbalanced and the seat belt left strangulation marks on the deceased?"

"If that's the case, Akikawa Sosuke, who was sitting in the passenger seat and weighed less than his mother, should have had a mark in the opposite direction."

"And yesterday, Conan helped me check the suspect Akikawa's body, and found no such marks."

Nakajima Takuto nodded slightly, "Indeed, he does look much weaker than his mother. Logically, the impact force that was enough to leave belt marks on his mother should have left marks on him as well."

"Of course, I also checked the victim's body yesterday and confirmed that he was not prone to scarring. This shows that the seat belt scar was not left in a car accident."

"Then it can only be left behind by the victim during his violent struggle after being stabbed."

"Knowing this, we can conclude that the stabbing with a dagger took place after the car accident. And then, I heard that triazolam was found in the body of the suspect Akikawa, right?"

"Yes."

"Then the whole process of the case has become clear." Sera Masumi said with a smile.

"That is to say." Nakajima Takuto suddenly became excited, "Have you already got solid evidence?"

"No"

The smile on Sera Masumi's face suddenly turned into embarrassment.

"No fingerprints of Akikawa Sosuke were found on the dagger or the body of the deceased, and the car was not locked when Officer Miyamoto found it. The car was old and did not have an automatic locking function. The witness testimony about the rear-end collision was also somewhat unclear."

"In other words, there is still a tiny possibility that a third party committed the crime."

"."

Takuto Nakajima felt a little speechless.

Akikawa Sosuke's motive, crime process, and murder weapon have all been determined.

There are no other suspects at the scene.

That basically confirmed that the detective's judgment yesterday was not wrong, and it was indeed Akikawa Sosuke who killed someone.

The only thing missing is evidence that Akikawa Sosuke is the murderer.

This situation is not uncommon. The Metropolitan Police Department has always either interrogated the suspect or asked him to confess voluntarily.

The former requires a lot of visits and investigations.

Although the detectives have obtained a search warrant, it will take some time.

It would be best if he could get Akikawa Sosuke to confess his guilt before that.

It can not only save manpower and time, but also gain merit.

"It's almost time. I should go get him food."

Nakajima Takuto stood up and left the room.

"Although it's a bit inappropriate to use this word to describe a murderer, I still think that Qiuchuan is not a bad person."

"After all, it was his mother who made the mistake first. He was locked up at home every day and he probably didn't have the basic legal literacy to do such a thing impulsively."

"If I go back this time and have a good talk with him, he will probably admit it on his own initiative."

Takuto Nakajima thought to himself, and then walked towards the direction of the meal being prepared in the hospital.

"Indeed, as Inspector Toda said, this is much easier than wasting manpower and time on investigations."
