In Conan, people have a brain option system

Ten minutes ago.

In the laundry room of the Empire Theatre.

Megure Thirteen, Chiba Kazanobu, Mouri Kogoro and several police officers present listened to Sera Masumi's reasoning.

The weapon used by the murderer to strangle the deceased was known.

"Then the last thing left is to determine the time of the death of the deceased and lock in the time period when we need to confirm the alibi with the suspect."

As Memu Thirteen said, he heard Conan's childish voice in the laundry room:

"Hey! There are light red patches on the dead brother's back!"

Everyone in the room looked in the direction of the sound.

Then I saw Conan wearing a red bow tie.

He actually lifted up the deceased's clothes and stared at the deceased's back with a surprised expression.

"Hey——! You brat, what are you doing again!!"

Mouri Kogoro rushed forward, picked up Conan by the back of his collar, and threw him away.

"That's a dead person! Moreover, disturbing the body may destroy important evidence!"

Mouri Kogoro looked at Conan and said with some annoyance.

"No, thanks to little brother Conan, we should be able to pinpoint the time of the deceased's death."

As Detective Chiba Kazunobu spoke, he stepped forward, lifted the body of the deceased from the side, and then lifted off the clothes of the deceased.

Then I discovered that it was exactly what Conan said.

There were many light red and lavender patches on the deceased's back.

"These are body spots, which usually appear within half an hour to two hours after a person dies, depending on the ambient temperature."

Sera Masumi walked to the corpse and squatted down. After observing the corpse spots on the deceased's back, he explained aloud.

"Plachma is a phenomenon where blood is deposited in low areas of the body after it has stagnated."

"When we found the deceased, he was lying on his back, so the blood would naturally sink to his back."

"If my guess is correct, the deceased's buttocks and hind legs should also have the same spots on his body."

Hearing this, Chiba and Shin also lifted up the deceased's pants, nodded and said:

"That's right."

"In other words, the deceased remained lying on his back after death." Mouri Kogoro said.

"Yes."

Sera Masumi nodded.

"If the body is moved after death, the spots in the original location may partially or completely disappear and reform in the new location."

"These changes can help infer whether the body has been moved."

Masumi Sera stretched out her hand to the back of the deceased.

She stretched out her fingers and pressed the spots on the deceased's back through her gloves.

It was found that the color of the light red corpse spots will fade quickly after being pressed.

"The corpse spots on the back of the deceased still have the characteristic of fading after being pressed, so it can be judged that this is still in the early stage of corpse spots."

"In addition, although the deceased had body spots, he did not suffer from rigor mortis."

"We can tell that the deceased died within two hours."

"Many criminals know that rigor mortis will appear about two hours after death, but many people do not know that corpse spots will appear half an hour after death, so they think that the police cannot determine the time of death of the deceased."

Mumu Shisan nodded and added.

"Since this body only has spots and no rigor mortis, that means the deceased should have died about half an hour ago?"

Mouri Kogoro stroked his chin with his hand and analyzed.

"No!"

Conan once again rejected Mouri Kogoro's judgment.

"Sister Sera just said that the appearance of corpse spots will also change depending on the ambient temperature."

"Uncle, don't you think that the temperature in this room is much colder than other rooms?"

“Indeed”

"It seems so."

Several police officers nodded when they heard Conan's words.

Sera Masumi also continued to explain:

"The air conditioning is not turned on in the laundry room, and the indoor temperature is undoubtedly lower than the normal ambient temperature of 20 degrees Celsius, so this is a 'low temperature environment.'"

"At this temperature, the appearance of corpse spots will be greatly delayed."

"In this case, the time of death of the deceased should not be about half an hour, but about one to two hours."

"In addition, I have just judged that the current corpse stains are still in the 'initial stage', so the correct time of death of the deceased should be an hour ago."

"That is, the period between before the second act of the stage play begins and just after the second act begins."

"In addition, Akikawa said that he was told to go to the laundry room at the beginning of the second act, and he only left after watching the performance of the second act."

"If this is true, then he would not have the conditions to commit the crime."

"Because the deceased was still in his dressing room when he was killed."

"And because Akikawa arrived at the laundry room much later than the murderer expected, the murderer fled the laundry room in a hurry."

"In this case, there was absolutely no way he could properly dispose of the murder weapon."

As Sera Masumi said, she also patted her palms lightly.

"Now the full picture of this case is clear, and it's time to find out the real culprit!"

——

"Excuse me, what was Mr. Nishihara doing at the beginning of the second act?"

Sera Masumi looked at Koichi Nishihara who was obviously shaken in front of him with a smile, and repeated his question again.

"I was in my lounge."

Nishihara Koichi answered.

"Can anyone please prove this to Mr. Nishihara?"

"No."

At this time, another police officer in charge of questioning came back and reported to Memu Thirteen:

"I have just confirmed what Ms. Yoko said with director Nakamura. He confirmed that Mr. Nishihara and Mr. Akikawa auditioned for the same role and failed."

"In addition, Director Nakamura also mentioned another point."

"That is, with Mr. Nishihara's status in the Japanese film and television industry, it is a bit strange to come and audition for a minor supporting role."

After hearing what the police said, the surrounding artists started talking.

"Indeed, I was a little surprised at first. It's very strange that Mr. Nishihara would come to the stage to play a supporting role."

"Yes, yes, and Mr. Nishihara has no experience in stage plays before."

As soon as Nishihara Ko heard the comments from the people around him, his already chaotic heart began to become even more panicked.

Conan looked at Nishihara Koichi's reaction and raised the corner of his mouth slightly.

Then he came to Okino Yoko, raised his head, and showed a confused and innocent look:

"Miss Yoko, didn't you warn Mr. Nishihara not to have any contact with Brother Akikawa again?"

"I think Ms. Yoko gave the warning not just because Mr. Nishihara once auditioned with Brother Akikawa and failed, right?"

Okino Yoko looked at Conan with a troubled expression.

After a moment, she whispered:

"Conan-kun is right."

"Mr. Nishihara, he committed two violent incidents of wounding in middle school and high school."

"I was worried that Mr. Akikawa would be harmed, so I warned Mr. Nishihara."
