Detective Conan: Twelve Death Warlocks

When the police were called, Guo Yixin was still yawning in the dormitory of Dongdu University. Her cousin simply tortured her to the point where it could not be further improved.

Looking at the time, it was just past 8:30, but the call was from Miwako Sato, who was on night shift, so she rushed to the scene in casual clothes. The person who died was Numata Jujiro, a graduate student at the school, and the person who found the body was

But it was Miss Yong Shanmao, the secretary of the instructor in charge of the laboratory, Jin Junyou.

Guo Yixin brought her trainee police officer's certificate with her and quickly took over the scene, while Chiba Kazunobu arrived with people soon after changing shifts.

"Sakuranomiya, didn't you sleep well last night?" Chiba Kazuno looked at her drooping eyelids, looking a little surprised.

"Forget it, the instructor assigned a lot of homework, and I checked the information until five o'clock in the morning. As a result, just after eight o'clock, Officer Sato called. So I hurried to the scene. At present, it seems that it should be

Sudden death is the right thing to do."

"No!" A voice suddenly appeared behind them.

Miwako Sakuramiya turned her head and looked a little surprised: "Mr. Subaru, do you also work in this laboratory?"

This person was none other than Subaru Okiya, who had disappeared for a while. Subaru Okiya smiled, but then looked at the scene: "Judging from the condition of the corpse, it seems that the face is a little distorted, as if he had experienced a great deal of pain before death.

It was painful, and there was no obvious trauma on the body. Judging from the degree of rigor mortis after death, it had been at least about seven to twelve hours. There seemed to be some vomit near the bottom of the deceased's head, yes.

Right! So, overall, it’s more like poisoning.”

"Poison?" Chiba and Nobu were a little surprised, but then nodded, Subaru Okiya was right.

Okiya Subaru just smiled, and then said: "However, before that, it is better to retrieve the surveillance video first, maybe we can find something else. I still have work in the laboratory, so I left.

"

Seeing Subaru Okiya leave, Chiba and Shin were somewhat surprised, and couldn't help but frown, because the man in front of him made it difficult to see his inner thoughts.

Through the surveillance video at the door, it was found that the deceased Jujiro Numata did not leave the laboratory last night, and no one came in. Chiba Kazuno couldn't help but frowned, and asked the secretary Nagayama Neko about the situation: "In addition, there are

Is there somewhere else I can go out?”

"No." Yong Shanmao shook his head gently.

Chiba Kazunobu said nothing and asked other police officers to continue the investigation. At nine o'clock in the morning, others also arrived, including their teacher Kon Junyu. But without exception, they were all invited to the building next to them.

, everyone was a little confused and didn’t know what happened in the laboratory.

Half an hour later, Kazanobu Chiba and Miwako Sakuramiya arrived in the room and sat on the other side of the table. Secretary Nagayama Neko, who came in behind them, also walked in and sat with his colleagues. Waiting for everyone to sit down.

, Chiba Kazushi looked at them, took the report and said: "Now let's report the case."

Sakuramiya Miwako sat next to me and took notes.

"In fact, around eight o'clock in the morning, the Metropolitan Police Department received a report from Ms. Nagayama that Toto University graduate student Jujiro Numata died in the laboratory where he was researching."

Kon Junyu was obviously a little surprised: "What did you say? Numata...is dead?"

Chiba and Shin nodded slightly, but still said: "So, I want to hear your opinions."

Everyone's expressions changed, but Konshunyu spoke first: "Numata is a graduate student I recruited recently. He has been helping everyone, but his personality is a bit irritable. I remember that he seemed to be doing some experiments again last night.

As a result, Numata was still in the overtime room before I left."

Chiba Heshen nodded slightly. He had seen this on the surveillance camera.

Secretary Naga Shanmao answered and added: "In fact, he is re-doing Miss Irie's experiment. I remember they had a dispute yesterday afternoon, and Numata was scolded by Irie."

Irie Xixia had a headache: "It was because he put the labels wrong and forgot the order, so he had to redo them. But he was present when the experiment was done before, so he said he would supplement the experimental subjects on my behalf, but I didn't expect him

I actually did this experiment so late at night. In the final analysis, I was too impatient, and this child was really..."

Seeing that Miwako Sakuramiya had already memorized it, Kazunobu Chiba nodded slightly: "I already understand the general outline of the matter. However, the police investigation found that this was a poisoning case, and it is certain that

, the murderer is among you. Therefore, I would also like to ask you to check your belongings and ask you some relevant information."

Chiba Kazushi's words caught them by surprise. They originally thought he died suddenly, but the incident turned into a poisoning case.

Jin Junyu nodded slightly: "Okay, after all, Numata is also my student, and I also want to know the truth about his death. Let's start with me!"

"Thank you for supporting our work."

Sakuramiya Miwako picked up the report that Chiba Kazunobu had left there, flipped through a few pages, took photos and sent them to a certain famous detective. When he saw the information, the other party was also shocked, and then frowned.

The police's evidence collection work was actually very detailed, but they lacked the organic combination of evidence. There was no obvious poisonous reaction at the scene, so they could only investigate from other places. However, the only thing found in the medicine cabinet was sulfuric acid (H2SO4

), hydrochloric acid (HCL), glacial vinegar (CH3COOH) and ethanol (CH3CH2OH).

"It shouldn't be these."

"But I think it's some plant alkaloids! It's also very toxic. It's like that drug called scopolamine."

Conan nodded slightly and sent this to Miwako Sakuramiya, asking her to call the police for analysis. However, Haibara Ai next to her was a little emotional: "Isn't there a liquid chromatograph that can be analyzed at this site? As long as it is carried out.

If you check it, you should find other ingredients. However, coffee is also a plant at the moment, and even if you use other instruments, you can't find anything else."

Conan couldn't help but be a little surprised, but he didn't say anything else immediately. As a forward-looking scientist, Haihara Ai can create such a heaven-defying drug - APTX4869, which means that she is very clear about this. So she doesn't know what's going on.

There is no need to doubt whether there is a problem with Haihara Ai's inference.

Because professional personnel quickly tested the coffee, they found the presence of an organic substance that was not coffee, which surprised Miwako Sakuramiya.
