Chapter 163 Doubts (12)

The detectives at the scene were divided into two groups.

A group of people went to look for the black suitcase used to dump the body.

Another group of people went to the guest room area on the second floor to search the rooms of the three suspects and the deceased.

It's almost seven-thirty in the morning.

Many tourists have already woken up.

In addition, the group of people who came to search the room was quite large, so many people opened the door and checked the situation out of curiosity.

Japanese criminal police are not like traffic police; they usually do not wear police uniforms when investigating cases.

However, the criminal policemen's uniform formal attire and their temperament that was completely different from other tourists still made many tourists recognize their identities.

Itakura Misaki also opened the door and stuck her head out to check the situation.

In the morning, she vaguely heard the sound of sirens in her sleep, and then woke up immediately.

Although there is no basis for this, whenever Itakura Misaki learns that a case has occurred, she subconsciously feels that it is her artist who has been murdered.

She also hurriedly contacted Akikawa Sosuke.

However, no response was received.

"I feel like I'm having a nervous breakdown. Whenever I hear a siren, my heart starts pounding."

Itakura Misaki prayed in her heart that Akigawa Sousuke just hadn't gotten up yet.

Then, several people who looked like detectives were seen standing at the door of Akikawa Sosuke's room.

"!!!"

Itakura Misaki felt her heart sink suddenly, and then she hurried out.

"Hello, may I ask what happened?"

Itakura Misaki asked the people who looked like detectives who were about to enter Akikawa Sorasuke's room.

"Do you know Akikawa Sosuke?"

The detective looked over and asked.

"I'm Mr. Akikawa's agent. Could it be that Mr. Akikawa has been murdered again?"

"again?"

The two detectives looked at each other, confused by what Itakura Misaki said.

What do you mean?
Could it be that the person who lives here is often murdered?

"It's not that someone was murdered, someone died. Akikawa Sosuke is one of the suspects, and we are going to search his room now.

"Is that so? That's great."

Itakura Misaki also breathed a sigh of relief when she heard this.

The two detectives were also confused when they saw Itakura Misaki's reaction.

What's going on? When this female agent saw that her own artist was suspected of being the murderer, she looked relieved?
After thanking the two detectives, Itakura Misaki returned to her room.

After closing the door, she patted her chest, where her heart was pounding, and let out a long breath.

"It turns out that he was not murdered, but was treated as a suspect."

Having spent such a long time with Akikawa Sosuke, she still has great confidence in the character of her artist.

In Itakura Misaki's heart.

Akikawa Sosuke is like a little white rabbit, simple, cute and harmless.

Although sometimes Akikawa Sosuke can guess what other people are thinking, which is a bit scary.

However, Itakura Misaki believes that Akikawa Sousuke will neither do nor have the ability to do anything to harm others.
-

the other side.

Professor Agasa, a group of little guys from the Junior Detective League, and several detectives are in the room of the deceased Kenji Furusawa.

However, Kenji Furusawa's room was clean.

I didn’t see anything that could be used to make hydrogen sulfide gas. “The air conditioner in the room was always on, and the room card was inserted into the card-operated switch.”

"There is only one room card per person. If Kenji Furusawa wants to leave the room, he will definitely take the room card with him."

"Of course, there is also the possibility that Kenji Furusawa got drunk and forgot to take the room card, but judging from the indentations on the bed sheet, this is undoubtedly the murder scene."

Conan looked at the wrinkles on the bed sheet and muttered to himself.

It can be clearly seen that there are traces of someone lying on the white sheets and being dragged.

"If this is a murder scene, it doesn't make sense."

Haibara Ai, who was next to Conan, spoke.

"The first thing the detective did when he entered the room just now was to detect the concentration of hydrogen sulfide in the room."

"The detection equipment did not show any numerical value, which means that the concentration of hydrogen sulfide in the air in the room is so low that it cannot be detected at all."

"Moreover, the windows in the room were not opened, and the ventilation system was also not turned on."

"If the murderer killed Kenji Furusawa with hydrogen sulfide gas here, how is it possible that there is not even a trace of hydrogen sulfide detected in the room?"

At this time, the police had also finished searching Kenji Furusawa's personal belongings and everything in the room.

"It seems that there is nothing suspicious here."

"Excuse me, is it possible to make hydrogen sulfide gas using the things already in the room?"

A detective came forward and asked Dr. Agasa.

"impossible!"

Dr. Agasa was about to speak, but Haibara Ai answered the detective's question first.

"Hydrogen sulfide is definitely not a gas that can be easily produced using common things in daily life."

"Otherwise, anyone can easily kill people with hydrogen sulfide."

When the detective saw that the person answering his question was a little girl who looked only 7-8 years old, he showed an expression of surprise.

What amazed them even more was...

The little boy wearing round-frame glasses next to the little girl with brown short hair also said something quite shocking:

"Is hydrogen sulfide difficult to make? Isn't it easy to make it by using something containing sulfide and reacting it with acid?"

"I remember that some shampoos and shower gels contain sulfide ingredients, right? For example, selenium sulfide or something like that."

Conan asked doubtfully.

Anti-dandruff shampoos usually contain selenium sulfide, which has anti-fungal and sebum secretion regulating effects.

Conan speculated that perhaps the murderer used shampoo to make hydrogen sulfide.

However, his guess was quickly denied by Haibara Ai.

"No, first of all, the chemical properties of selenium sulfide are relatively stable, and the possibility of it reacting with acid to produce hydrogen sulfide is very low."

"Secondly, the concentration of selenium sulfide in regular shampoo is very low. Even if it is used to produce hydrogen sulfide gas, the concentration is not enough to kill people."

As the developer of the second-generation APTX-4869 drug, Haihara Ai has extensive knowledge in pharmacology, toxicology, biochemistry and other related fields.

Because of this, she was able to determine from the concentration of hydrogen sulfide in the air at the scene that this was a homicide.

Similarly, this room was the murder scene, but there was not a trace of hydrogen sulfide remaining in the air, which made Haibara Ai feel that something was very wrong.

Hearing this, Conan once again showed a thoughtful expression.

"So there are two suspicious points in this case."

"How did the murderer make hydrogen sulfide?"

"And how did he manage to ensure that there was not even a trace of hydrogen sulfide left in the air at the crime scene?"

Just when Conan was confused, he suddenly heard Kojima Genta's excited voice:

"Wow! Look, it's Kamen Rider's mask!"
