Conan, My Neighbor Kurosawa Jin

Looking at Conan's running figure, Toru Amuro had a smile on his face. It seemed that he would soon know who the murderer was.

Half an hour later, when Officer Megure and the others were still carefully investigating clues and investigating whether there was any conflict between the four suspects and the deceased, Toru Amuro suddenly stood up.

"Officer Megure, I already know who the murderer is."

"Mr. Amuro, is it true?" Officer Megure was a little surprised. Although Toru Amuro had been following them just now, he didn't seem to be searching for anything. How could he suddenly figure out who the murderer was?

But thinking about Tohru Amuro's outstanding performance in previous cases, Officer Megure put aside his doubts.

"Aren't you just a waiter?"

"Yes, aren't you still a detective?"

"Officer, it's up to you to investigate!"

Several suspects were noisy, obviously not believing Amuro Toru at all.

"Quiet, everyone, please be quiet!" Officer Takagi clapped his hands and signaled everyone to quiet down. Seeing that everyone stopped talking, he explained that Toru Amuro was a detective and introduced Toru Amuro's past. Help the police solve the case through reasoning.

Seeing that the police had said this, the suspects calmed down and stopped looking at Toru Amuro with suspicion.

"The cause of death of the deceased was indeed poisoning. Through monitoring and testing of the food he ate, it can be inferred that the deceased died of a disulfiram-like reaction.

What can cause this reaction is generally taking drugs containing alcohol and disulfiram-like structures, the most common ones being alcohol and cephalosporins.

Coupled with the time of death and the fact that the deceased took something before death, it can be inferred that the murderer is indeed among the four of you. "After Toru Amuro finished speaking, he looked at the four suspects and saw no big reaction, and then continued, "After checking the surveillance, the deceased only drank a cup of coffee and a cup of lemonade before his death. Didn't eat anything else.

Originally, I thought the deceased drank the wrong coffee from the second suspect. He drank the other suspect’s coffee containing alcohol and then took cephalosporins, which led to a disulfiram-like reaction. However, after detailed inspection by the forensic department, it was found that the coffee the deceased drank was indeed his own cup, and it did not contain alcohol.

This also made me suspicious, wondering if there was a mistake in my inference. But then I heard what Yuantai said, and I suddenly had a new idea. What if the deceased's coffee contained more cephalosporins than alcohol?

What the deceased took later was not cephalosporins, but alcohol.

Someone secretly changed the deceased's medication while he was not paying attention, replacing the cephalosporins he was taking with capsules containing alcohol.

Then he added cephalosporin powder to what the deceased ordered. Coffee is inherently bitter, and even if cephalosporin has some bitter taste, it can be well concealed without being discovered by the deceased.

Then, as long as something happens to the deceased, and taking advantage of the chaos, he secretly replaces the medicine on the deceased, then everything can be concealed.

I had previously asked the police officers from the forensics department to investigate the contents of the coffee, and indeed a large amount of cephalosporins were found in it. Now, just check their belongings and take a look at the medicine capsules they carry. Pretending to be what this is, everything will be revealed. "

"Please, please cooperate with our investigation!" After receiving confirmation from the forensic department, Officer Megure and the others surrounded the four suspects and looked at them seriously.

The four of them were all a little panicked, but facing the police's gaze, they still handed over everything they had in their hands. Only the first suspect was very panicked and held on to his backpack tightly without letting go.

Looking at her expression, Officer Megure and the others already knew who the murderer was.

Facing the gaze of Officer Megure and the others, the first suspect finally gave up after a long stalemate, and then he fell down on a chair nearby, his face pale and his head lowered, without looking at Officer Takagi. What was found inside the bag.

After all, she knew exactly what was in her bag.

Officer Takagi successfully found a bottle of medicine in his backpack. The capsules inside were very similar to those taken by the deceased. When they checked before, they thought it was just an ordinary medicine, so they didn't carefully check the contents of the capsule.

After all, the deceased died of a disulfiram-like reaction, and everyone subconsciously thought that the drug the deceased took was cephalosporin. If this was the case, there was no possibility that anyone else would use drugs to kill the deceased.

But now, even without the police from the forensics department, Officer Takagi immediately knew what was inside the capsule the moment he opened it.

Looking at the viscous liquid with a strong alcohol flavor flowing out of the capsule, Officer Takagi nodded to Officer Megure, and everyone looked at the first guest.

"It was indeed me. I pretended to accidentally bump into each other while the clerk was serving them coffee, and took the opportunity to sprinkle the medicine in my finger into the non-alcoholic coffee.

The medicine I gave dissolved quickly, and the clerk didn't notice it, so she handed them two cups of coffee, and as expected, the man chose the one without the alcohol smell. "The first customer lowered her head and said, since the capsule has been found on her body, she has been exposed. As for other evidence, it can be easily found under the police's investigation.

"Why did you kill the deceased? Was it because of the photos?"

"It's not just those photos. If you're just being photographed smoking, drinking, or getting tattoos, it doesn't really matter. It's all in the past. The school may not give me a promotion because of these, but it's also impossible because of this. I was fired, and at worst I could become an ordinary teacher.

In addition to smoking, drinking, and getting tattoos, I also did some outrageous things at that time. Once those things were exposed, I would go to jail. And he happened to take those photos and used them to threaten me. In fact, this is not the first time he has come to me, but it was just secretly before. "The first customer said in a broken voice. If the money was just for smoking, drinking, and getting tattoos, it would be fine. These are not illegal, but when she was a member of society, she had hurt people and even left them disabled and seriously injured.

Later, I felt scared because of this incident, so I changed my mind and went to college again with a different identity.

Now, except for her parents, no one knows about her past.

But this man actually found her with her previous photos and threatened her that if she didn't get money, he would send these photos to the school.

Seeing that the other party's appetite was getting bigger every time, the first guest finally couldn't bear it anymore. She had dared to kill people before when she was a teenager, let alone now.

"How did you switch the drugs? How did you know that the deceased would definitely take the capsules." Officer Takagi asked.

“We met before, and it happened that one time he had a cold and was taking cephalosporin, and I remembered the medicine he took at that time.

The last time we met, I deliberately made him sick and caught a cold. I guessed that he would definitely still take cephalosporins this time. Later, while the two of us were meeting, I changed the medicine in his bag while he was not paying attention.

The result was just as I expected. As long as he ate the cephalosporins I replaced and drank coffee, he would definitely be poisoned.

And I took advantage of the chaos to secretly replace the medicine on him. "The first guest said honestly. After speaking, he stretched out his hand, revealing his long nails.

"Did you hide the medicine under your nails?" Azusa Enomoto suddenly wondered when the first customer added something to the coffee.

"Well, I ground the cephalosporin into powder and hid it in my nails. After I finished injecting it, I washed it off, but I think I can still check it out, right?" The first guest leaned on the chair, with a trace on the corner of his mouth. A mocking smile.

Officer Takagi nodded. If it were a group of people, the police would not check everyone's fingernails carefully, not to mention that the drugs inside were non-toxic anti-inflammatory drugs.

But if there is only one suspect, how can it be impossible to find him?
