In Conan, people have a brain option system.

Chapter 86: Locking in the Murderer
"Is my unit dead?!"

When Akikawa Sosuke heard what Maori Ran said, he was also a little surprised.

He also had an impression of the director named "Sogabe".

He was one of the directors sitting at the first table where Yoko Nono took him to say hello at the dinner yesterday.

Akikawa Sosuke clearly remembered that Sogabe Ryo looked drowsy throughout the dinner.

And after being teased by Yoko Okino, he said that if he had known earlier, he should have slept in the hotel.

"Both Tsunekazu Kosaka and Ryo Sogabe were directors I greeted at the first table."

'There is only one person left, and that is Soma Miho, who had been joking with Okino Yoko and suddenly had a backache before shaking hands with me.'

'Although the situations of Tsunekazu Kosaka, Ryo Sogabe, and Miho Soma are different, they all have something in common.'

'Now that we know that Doctor Ohkawa Takao knows Kosaka Tsunekazu, there is a high possibility that he knows the remaining two.'

"If the cause of Sogabe Ryo's death is similar to that of Kosaka Tsunekazu, then the murderer is most likely Horita Yoshitoki, who had a grudge against Ohkawa Takao."

Akikawa Sosuke keenly realized the connection between Sogabe Ryo's death and yesterday's case.

But there was still something about this matter that made him feel uncomfortable.

That was when Takao Ohkawa just invited himself to Yoshitoki Horita's personal exhibition hall.

"If it was Yoshitoki Hotta who invited me, I would understand."

'He probably wants me to provide him with an alibi.'

'Or, if you think about it more extreme, he might even want to pin the blame of his murder on me.'

"But in this case, Takao Ohkawa is clearly the 'victim'."

'Then what was his purpose in inviting me to the Yoshitoki Horita exhibition hall?'

Just when Akikawa Sosuke was unable to make an accurate judgment due to the lack of known information,
Then Ran Mao Li whispered to Suzuki Sonoko again:

"Sonoko, why don't we go over and take a look? I'm worried that Conan might be in danger."

"But isn't Sera there too?"

"But Sera is only one person after all. I'm not sure she can fully protect Conan."

"That's true. It's time for the great detective Suzuki Sonoko to appear."

Suzuki Sonoko was persuaded by Mouri Ran, and then stood up with her.

She looked at Akikawa Sosuke.

"Mr. Akikawa, Xiaolan and I will be out for a while. You and Ms. Itakura can stay here."

After Suzuki Sonoko finished speaking, she and Mouri Ran quickly walked towards the place where Sera Masumi and Conan had just left.

Akikawa Sosuke looked at Itakura Misaki who was standing aside.

"I'm going to the bathroom and will be back in a moment."

Itakura Misaki, who was sitting on the other side of Akigawa Sosuke, did not hear what Mori Ran whispered to Suzuki Sonoko, but she nodded slightly without any suspicion.

Akikawa Sosuke followed Mori Ran and Suzuki Sonoko from a distance behind.

We came to the personal lounge inside the exhibition hall, which was specially prepared for directors and screenwriters.

Here, Akikawa Sosuke saw several film exhibition staff and security personnel surrounding the personal lounge.

In Sogabe Ryo's lounge, Conan and Sera Masumi can be seen checking Sogabe Ryo's body lying on the ground.

"Forget about Sera Masumi, why was Conan, a primary school student, able to enter the crime scene so openly?"

Akikawa Sosuke was puzzled in his heart, and then moved a little closer to Sogabe Ryo's lounge.

Then I could see clearly that there were two very obvious holes on Sogabe Ryo's forehead and arm.

"Gunshot wound?!" Akikawa Sosuke was extremely shocked after seeing this scene.

He thought that Sogabe Ryo had died in the same way as yesterday, due to breathing problems.

However, I didn't expect that his way of death was completely different from yesterday, it was a more direct gunshot wound.

"I can't see the wound on my forehead clearly, but I guess it's a blind spot wound."

'The wound on the arm is a penetrating wound, and the wound on the arm has life reactions.'

The so-called blind tube injury, simply put, is the damage caused by the bullet remaining in the body.

A penetrating wound is one in which the bullet penetrates the body and then exits the body.

'That is to say, the murderer shot Sogabe Ryo in the arm first, and then shot him in the forehead.'

Akikawa Sosuke was very familiar with gunshot wounds, so he was able to determine the source of Sogabe Ryo's wounds and the cause of death at just one glance.

He began to observe the blood on Sogabe Ryo's forehead and arms.

I found that the color of the blood was no longer bright red or dark red, but was gradually approaching dark red.

But the room temperature will also affect the change of blood color.

Now Akikawa Sosuke was just looking from a distance and was unable to get close to Sogabe's personal lounge, so he had no way of judging the specific temperature inside the room.

'The running time of Sogabe Ryo's film is 70 minutes, and after the screening, there is 15 minutes for the audience to leave and for the staff to clean up.'

'Sogabe Ryo needs to give a speech before the movie starts, which means he is still alive before the last movie is shown.'

'That way, including the time we had to wait before the movie started, his death would have taken no more than 100 minutes.'

'So the environment in the room cannot be a "low temperature environment" below 10 degrees Celsius, because 100 minutes is not enough for the blood in a low temperature environment to turn this dark red.'

'The handsome detective is fine, but the Death God's elementary school student has sweat on his neck and forehead, so the indoor environment is probably a "high temperature environment" of over 30 degrees Celsius.'

"Then, considering the "high temperature environment" of over 30 degrees Celsius, Sogabe Ryo's death should have been less than an hour."

Akikawa Sosuke also made a rough estimate of the indoor temperature of Sogabe Ryo's personal lounge and the time when he was killed.

Although there must be a lot of people entering and leaving the exhibition hall during this period.

This little bit of information alone is not enough to identify the murderer.

However, the death of Sogabe Ryo made Akikawa Sosuke instantly sort out the confusion in his mind.

Why was Sogabe Ryo's death different from that of Kousaka Tsunekazu yesterday?
Why did Takao Ohkawa, who was clearly the "victim", invite himself to go to Yoshitoki Horita's exhibition hall at one o'clock?

The reason is——

Although Tsunekazu Kosaka and Ryo Sogabe have something in common,
But the murderer who killed the two was a completely different person.

It is still unclear whether the person who killed the former was Yoshitoki Horita.

But the murderer who killed the latter is already very clear.

The murderer changed the temperature in the room simply to make the police and detectives misjudge the time of death of the deceased.

If the indoor temperature is kept at a normal temperature of 20-25℃,

It takes at least 60 minutes for the blood to turn from bright red to dark red.

At that time, Akikawa Sosuke was still watching a movie with Itakura Misaki in Oda Ema's screening room.

The same is true for the Death God Student and others.

In addition, there is another character who also has an alibi and is related to Sogabe Ryo.

——Takao Ohkawa, a plastic surgeon who graduated from the Faculty of Medicine of the University of Tokyo.
