In Conan, people have a brain option system.

Chapter 159: Outright Murder (12)

Conan hid behind Dr. Agasa and expressed his reasoning with the help of the bow voice changer.

Since Masumi Sera was not there this time, Conan had no way to properly examine the body.

Therefore, we can only judge the cause of death based on the current observed situation.

After hearing Dr. Agasa's (Conan) reasoning, the police officers present all nodded and showed expressions of sudden enlightenment.

However, the inspector of the Kanagawa Prefectural Police Headquarters obviously still had doubts about the cause of death of Kenji Furusawa.

After all, in Hakone, a place with natural hot springs and close to volcanoes,

Hydrogen sulfide poisoning is not an uncommon condition.

"Dr. Agasa, did you conclude that the deceased did not die of drowning simply because he did not float on the water?"

"In Hakone, hydrogen sulfide poisoning is not uncommon, but there have been almost no deaths from hydrogen sulfide poisoning."

"Generally speaking, hydrogen sulfide poisoning would at most cause coma."

Hearing the words of the deputy inspector, Kunio Koizumi, the owner of Kosenan, also interrupted and echoed:

"Yes, this happens occasionally in Hakone."

"That is, someone inhaled too much hydrogen sulfide gas without realizing it, causing their head to become unclear and they fell into the hot spring."

"And this Mr. Gu Ze appeared in the female hot spring area. I think he might want to sneak into the female hot spring area and do some perverted things while no one is there."

"As a result, he accidentally fell into the hot spring and drowned."

"No, although this is possible, the cause of death in this case was clearly not drowning."

Conan spoke up and denied what Inspector Koizumi Kunio said.

"First of all, if the deceased accidentally fell into the hot spring, he would have struggled and tried to breathe while drowning, which would have caused a large amount of water and air to be inhaled into his respiratory tract."

"Because the airway is partially blocked by water, air and water will mix together and enter the lungs, which will cause the body to float faster."

"This time the deceased did not have this situation, which means he must have lost consciousness when he entered the hot spring."

"That doesn't mean he died of hydrogen sulfide poisoning, does it?"

The hot spring hotel owner Kunio Koizumi continued to ask.

"At least a forensic autopsy should be performed to confirm that he really didn't die from drowning, right?"

Generally speaking, if the police want to determine whether a person died from drowning, they must perform a forensic autopsy.

After cutting open the deceased's lungs, observe whether the lungs are over-inflated and whether a large amount of pink foam appears to determine whether the deceased died of drowning.

“In fact, even without a forensic autopsy, it is possible to determine whether the deceased died of drowning.”

"You can directly observe the secretions from the mouth and nose, or use a tracheal tube to obtain a sample of the fluid in the respiratory tract to determine whether there may be signs of drowning."

"The former only requires observation, while the latter can be determined with the help of the equipment in the ambulance."

Conan said.

"In addition, the characteristics of hydrogen sulfide poisoning victims include cyanosis of the skin and hypoxia. The victims' muscles also become loose and their eyes become bloodshot."

Upon hearing this, the inspector of Kanagawa Prefectural Police Headquarters quickly sent police officers to pry open the deceased's eyes.

Sure enough, it was discovered that under the deceased's bluish-purple eyelids, both eyeballs were congested.

"If it is true as the police officer said, that the deceased just inhaled too much hydrogen sulfide, causing his brain to become unconscious, it would be impossible for him to have such obvious symptoms of poisoning." "If you still don't believe what I say, Mr. Koizumi, you can also observe the deceased's blood."

"Hydrogen sulfide combines with hemoglobin to form sulfhemoglobin, which gives the blood an abnormal color. You will understand once you have seen it."

After hearing what Dr. Agasa said to this extent, Kunio Koizumi finally stopped arguing.

The deputy inspector who had been observing the situation from the side looked at Kunio Koizumi with suspicion and asked:

"Mr. Koizumi, you seem to be trying hard to deny that the deceased died of hydrogen sulfide poisoning."

"Could it be that you know something?"

After hearing the questions from the inspector, Kunio Koizumi immediately showed a frightened expression.

He hastened to avoid the officer's sight.

His reaction also made the surrounding police officers even more suspicious.

"No, it probably has nothing to do with Mr. Koizumi."

Just when everyone began to suspect Kunio Koizumi, Conan spoke again.

"I think Mr. Koizumi is just worried that the news that Mr. Kozawa died here from hydrogen sulfide poisoning will spread."

"After all, if Mr. Gu Ze accidentally fell into the water while trying to peek, then it has little to do with the hot spring hotel."

"And if Mr. Gu Ze died here due to hydrogen sulfide poisoning, it is very likely to affect the business of the hot spring hotel."

"After all, everyone knows that hydrogen sulfide may be produced in all the soil near the hot springs."

"If tourists thought that the hydrogen sulfide produced by the hot springs at Kosen-an was lethal, they would definitely not dare to come anymore."

After hearing Dr. Agasa's explanation, the police at the scene once again looked at Kunio Koizumi.

Then he saw Kunio Koizumi nodding awkwardly.

Faced with the death of a person in his own hot spring hotel, Kunio Koizumi's first reaction was to hope that it would not affect his business.

After realizing this, many police officers present showed a look of disgust on their faces.

But then, what Dr. Agasa said shocked the police and Kunio Koizumi:
"Don't worry about this, Mr. Koizumi."

"Because Mr. Guze's death was clearly not an accident, but a complete murder."

"And the person who did it must be in this hotel and is acquainted with Mr. Gu Ze."

When Conan said this, he suddenly heard a group of childish and familiar voices:
"It's finally time for our Junior Detective Team to make their debut—!"

Everyone present looked in the direction where the sound came from.

I saw three elementary school students, two boys and one girl, acting like detectives and speaking with confidence.

"Hey! What are you guys doing here? Go back now!"

When Haibara Ai saw Yoshida Ayumi and others suddenly appear, she hurried forward and wanted to push the little guys back.

However, Mitsuhiko Tsuburaya and Genta Kojima, who were very mischievous on weekdays, ignored Haibara Ai's orders as expected.

The three little guys all had extremely serious and solemn expressions on their faces.

"Someone actually killed Kamen Rider. This kind of thing is absolutely unforgivable!"
