Chapter 256 Mixing two detergents will produce poisonous gas

Thanks to Kudo Yusaku being a well-known mystery writer, fans often send fan letters to Kudo Shinichi. At the same time, many former die-hard fans of Kudo Shinichi also send letters to Kudo Shinichi.

Therefore, even if the black organization monitors the Kudo Shin family's mailbox and Aoki Matsuda adds a letter, it will not arouse the other party's suspicion.

What's more, by this time, Miyano Yasushi should have made changes to the death list, and the black organization will not continue to investigate whether Kudo Shinichi is dead or not for the time being.

At this time, even if Gin and Vodka did not catch the mole and counterfeit wine, they should still be keeping an eye on Miyano Akemi. Therefore, it is a very safe time to send the second letter to Conan at this time.

Just do it.

Aoki Song carefully held the envelope, took advantage of the lunch break, drove to the edge of the city, and stuffed the envelope with Osaka's characteristic stamps directly into a mailbox. He would have work in a few hours.

The personnel come to collect the letters uniformly, and then divide the letters into regions and deliver the letters one by one to the sender's address.

In the second letter, Aokimatsu didn't reveal anything more. He just told Conan that if they don't contact Miyano Akemi, there will be no way for Miyano Shiho to copy a complete APTX4869 through Miyano Akemi before escaping from the black organization.

Drug information.

As for time and operation, whether it can be successful or not, Aoki Song doesn't know.

However, he felt that there was a high chance of encountering a "plot kill" and it was impossible for Conan to obtain the complete information on the "APTX4869 drug" so easily.

This can also be regarded as an experiment by Aoki Song to see if Conan, as the protagonist, can't be invincible in the plot. If he can, then Conan is truly invincible.

If not, then everything is back to how it was in the cartoon, with no changes. Aoki Song has nothing to lose, since the guinea pig is not him anyway.

After sending the letter, Aoki Song was very relaxed and didn't care about Conan's reaction after receiving the letter.

Anyway, he has been hiding in the dark, and it is impossible for Conan to take off his vest. Aoki Song will not expose Conan's true identity foolishly. In this case, Conan will try his best to hide himself in front of Aoki Song.

's true identity.

Three layers of buff.

Completely stress-free.

I just don’t know if Conan will stop for a few days after receiving the letter.

Facts prove - no!

Early the next morning, the Metropolitan Police Department received a report from Mao Lilan. Needless to say, Aoki Song rushed to the scene with Takagi Wataru and others.

The scene is not big, but it is a bit shocking.

Because the workload was really heavy - the areas where the bathroom door, windows and walls were connected were covered with dense tape, and three big words "Farewell" were also taped on the glass door.

The first time he saw this scene, Aoki Song recalled this case in his mind.

There's no way this case is too classic.

Aoki Song also learned something from this case - do not use two different acid-base cleaners at the same time, because the mixture of two different acid-base cleaners will produce poisonous gas. If used in a closed room, it will cause poisoning.

die.

From then on, Aoki Song only bought these things from one brand.

He doesn't know much about acids and alkalis, and he has no interest in checking them online one by one. Moreover, even if he checks, the words on the Internet may not be correct. But there should be no problem with products under the same brand no matter how they are mixed.

question.

As usual, Aoki Song asked Takagi Wataru to understand the basic situation of the deceased, and he walked into the bathroom to inspect the scene after the Forensics Division took photos of various places at the scene.

At first glance, there are three strange places in this scene.

First, the deceased cut his wrists to death, but there were multiple scars on his wrists. Judging from these scars, the deceased cut his wrists many times, and he did not cut his wrists in one place, but he cut them over and over.

Moved the position slightly.

When people choose to commit suicide by cutting their wrists, it is indeed impossible to be as precise as a machine, and they will cut the same position every time. But people who really want to commit suicide will subconsciously try to move towards the same position in order to enlarge the wound and bleed more.

Cut.

As for the deceased, not only were there multiple scars on his wrist, but they were also in different directions. They looked like they were drawing an "X", with several cuts on the left and several on the right. The area was as wide as a knuckle, which was not normal.

Aoki Song remembers that when he took this class in the police academy, he said that whether it was a person who wanted to die or someone who was hesitant, if he chose to slit his wrist, the wounds would almost be parallel when he took the initiative and was not threatened.

Wounds, not such cross wounds.

Even if there is a slight angle error, it is unlikely that the angle between the two scars will reach 90 degrees.

Would someone really slit their wrists when committing suicide?

Second, the blood stains on the edge of the bathtub.

On the surface, after cutting his wrist, the deceased put his hand in a bathtub filled with water and pressed the heat preservation button in order to keep the wound on his wrist bleeding and cause him to bleed to death.

This method of suicide is not strange, but what is strange is that there are still blood spatters on the inner wall of the bathtub, but there are no blood stains on the top of the bathtub wall. Some of the blood stains are obviously wrong.

Some of them looked like someone had wiped away the blood stains on the bathtub wall. Of course, it was also possible that there was something on it at the time, but it was gone now.

In other words, this case is definitely not a suicide, but a homicide.

Of course, as Aoki Song, who has already recalled the course of this case, he not only knows who the murderer of this case is, but also knows where the evidence is.

However, you can't identify the murderer right away, otherwise it will arouse other people's suspicions.

The process that needs to be followed still needs to be followed.

The third strange place is not the two bottles of cleaning fluid poured on the floor, but the bathroom door.

No one else knows what fighting power Mouri Kogoro and Mouri Ran have, how could Aoki Song not know.

There is also a sister of the deceased. The bathroom door is a transparent glass door. Although I don’t know the quality, it is definitely not as good as an all-wooden door.

Even if it is fixed with tape, under the impact of Maori and his daughter, the door is not only not hit or damaged, but also the corners of the door frame are not deformed, and the connection with the wall is not loosened due to the huge force. The quality is really good.

.

Is there really such a door?

All metal security doors are not of such good quality!

Aoki Song still has great trust in the strength of Mouri Kogoro and Mouri Lan.

Not to mention that he recalled the case, even if he hadn't and without Conan as a guiding light, Aoki Song could still assert that this was definitely not a suicide.

After Aoki Song finished examining the crime scene, Takagi Wataru came over and reported, "The police department, the deceased's name is Qingdao Mina, and she is 24 years old. The person who discovered the deceased's death was the deceased's sister, Miss Qingdao Quandai."

A forensic criminal who followed Aoki Song out of the crime scene continued: "The cause of death of the deceased was a stab wound on his left wrist, accompanied by blood loss caused by a ruptured artery.

In addition, we also found hydrochloric acid and acidic bathroom cleaners in the corner of the bathroom. However, after testing, although the outer packaging of the cleaners is different, they are actually a kind of detergent and will not produce poisonous gas after mixing.

"

At this time, the "great smart" Mouri Kogoro on the side couldn't help but said: "Is it possible that Ms. Mina initially wanted to commit suicide by using the poisonous gas produced by mixing two different detergents, but only after sealing the bathroom, she discovered these two

The bottles of detergent are all the same, so this one was changed to suicide by cutting one's wrists."

Qingmusong shook his head, and then said decisively: "This is not suicide, this is homicide."

"This, how is this possible!" Mouri Kogoro was shocked.

Conan's eyes lit up when he heard this. He had already noticed the blood stains on the wall of the bathtub.

How could a person who wanted to commit suicide still have the heart to wipe the bathtub after cutting his wrists?

If there was something covering it, why didn't they find it after they broke into the bathroom?

There is only one situation that can explain all this - that is, the deceased was killed by him, the blood stains may have been wiped by the murderer accidentally, or the things placed there were taken away by the murderer.

[Sure enough, Brother Aoki’s judgment is that it was homicide. 】

Aoki Song's judgment also made Conan more convinced of his own ideas. This case was a homicide and not a suicide!

"Police Department, we found an invoice in the living room. Judging from the items purchased on it, it should be the origin of the two bottles of detergent in the bathroom." A criminal came over and said with an evidence bag.

Aoki Song took it and looked at it, then said: "Go to this convenience store to confirm this and see who purchased these things. It is best to have a witness or surveillance."

"Yes, I'll go right away." The other party responded.

At this time, the criminal officer from the forensics department also reported: "Police department, we have checked the tape on the door, and there is only one fingerprint on it, which should be that of Miss Qingdao Meicai."

"I see."

Qingmusong was not surprised by this, and even if there were Qingdao Quandai's fingerprints on it, the two sisters lived together, and the other party had an explanation.

Another criminal came over at this time to report that they found traces of tape on the edge of the coffee table in the living room.

"Miss Quandai, can you explain why there are traces of tape on all sides of the coffee table in the living room?" Aoki Song looked at Qingdao Quandai and asked.

Qingdao Quandai was a little nervous when he heard this. After all, the police officer in front of him insisted that this was a homicide, not a suicide. Qingdao Quandai was a little flustered, but he still said bravely: "I'm moving out soon, and I'm packing up my belongings."

When packing things, I need to use tape, so Meicai helped me tear it up and stick it around the coffee table."

Qingdao Quandai also thought about lying, but she was not the only one who knew about this. If that person heard the news, he would have rushed over immediately.

At other times, once her lies were exposed, the police would be more suspicious of her. It is not easy to tell the truth now and reduce their own suspicions.

Sure enough, after Qingdao Quandai said this, she saw that the police officer stopped asking her questions for the time being and seemed to have believed this reason.
