Detectives of Detective World

This assassination technique has various advantages.

But the only drawback is that it is too difficult.

"In other words, the prisoner knows the structure of the human body very well and is used to killing people like this?"

After hearing Karasawa's analysis, Ayanokouji Fumimaro frowned and said: "This is not something ordinary people can do. Even doctors who understand the structure of the human body may not be able to do it."

After all, theory is theory, but hands-on practice requires more experience.

"That's right, so I guess the other person is either a former soldier or a habitual murderer." Tang Ze nodded and said with a serious expression: "This prisoner is very dangerous."

"In fact, I have some suspicions that this is a serial killer."

Ayanokouji Fumimaro said: "I did some research before and found that this method is very similar to the murderer of the "Teenage Killer Serial Case" that appeared two years ago.

At that time, all three of them were fatally stabbed in the back, and they were called "Kyoto murderers" by the people of Kyoto. "

Following Ayanokouji Fumimaro's words, photos of three girls were displayed on the projection in the conference room in front.

Feiyu asked the director to send a new researcher to run errands with him.

Although there was no obvious retreat due to the identity of the prisoner, the appearance of that piece of evidence clarified the direction.

And that person also knew his identity and sent a letter to my house.

Feiyu nodded and said: "Do you know if you can find out where you got those spores?

"Thank you for your call. That's the Jingluo Hotel over there. You are Lishui, the backstage waiter, at your service. Is there anything I can help you with?"

On the other hand, if we focus on scientific research, all the evidence will be sent there for identification, ensuring that Feiyu can keep up with the progress of the case and can legitimately participate in the investigation.

"He is bad, you are Jun Tsukidate." The male researcher behind him looked young, and he was also a beautiful woman who would make Daishichirou Mouri look crazy and attentive.

Because there is no name under the letter, we also know who mailed it.

Cutting one side of the letter, the big white man took out the envelope and opened the white paper outside.

"A watch?" the man backstage asked sweetly: "Do you still remember the time and place?"

I knew that the other party wanted to call the police, but chose to send a letter instead. It was not because he wanted to threaten himself.

And the case was the "Multi-Male Killer Serial Case" two years later.

"Um."

Of course, we have also recruited very few new people for the sequel, so Feiyu saw that there were not many people on site who were more skilled.

I returned to the scene of the crime again and saw a hotel next to the renovated warehouse.

Tsukidate Jun finished looking at the zoomed-in image under the microscope and said, "That's right. Those steamed buns are often used over there."

Leaving the phone booth, the big white man slowly blended into the crowd.

Because Feiyu also worked with members of the local science search and research team in Kyoto to solve the case of "Arashiyama Girl", some members are still relatively unfamiliar.

Feiyu frowned and said thoughtfully: "But no matter what kind it is, that prisoner is obviously a "pleasure prisoner."

Luo Bi nodded, then took Qingtian Yuhua and left in a roundabout way.

Just when Fei Yu and the two were about to say goodbye, they unexpectedly thought that the office was suddenly pushed away.

After all, my purpose this time was not to provide some guidance to the Kyoto Science Research Institute, but in the name of participating in the case, it was also to observe the operation and guidance of the Science Research Institute on the spot.

In addition, during the autopsy, some slightly large substances were collected from the victim's nails. Unfortunately, the eighth person's skin was not detected.

The DNA of the beard collected from the fingernails of the second victim was exactly the same as that of the hair collected this time from Saru Tang Zeqi.

In addition to the footprints left by the deceased, another part was identified as the murderer's footprints. Except for the identification as female, there was no record before the database comparison.

Wu Sunli nodded repeatedly after hearing the other party's words, but he did not go to pick up the luggage immediately. Instead, he went to the refrigerator in the corner to get a drink of water.

"Ah, bad. You will investigate immediately and will contact you again. What is your contact information?"

And there was a sentence written under the letter.

And since you can clearly see the scene inside the house from above, if no one was standing in this position yesterday, it would be surprising to see yourself killing people.

But when I saw the content of the letter, my face instantly turned ferocious, and my eyes were full of scarlet murderous intent.

"It's easy." Tsukidate Jun shook his head and said: "As for the spores of shiitake mushrooms, it is impossible to stick to them even when cooking, so the source is very troublesome."

The address shown below is "Kobe".

"It's really a bad idea, Feiyu Criminal." Before Yue Guanjun finished explaining to the other party, he smiled apologetically at Luo Bi: "If you don't need help, he is welcome to come back at any time."

Naturally, we at Kesouyan have less professional staff. If we wanted to ask, we only went to the Fungi Research Institute in Kyoto.

I picked up the envelope again, and before checking it carelessly, I noticed that there was a postmark stamped under the surface.

That is absolutely tolerated by white people.

In those eight words, Jun Tsukidate explained the vagueness, and the office became intense again.

Then naturally I can only tell the other party to shut up.

And right now we are identifying those.

After all, when two people are working together, they still need a partner.

——[You saw him kill someone. 】

"Ah, it's used. You just found it. It's really troublesome!"

Now that the other party was killed using the same method, it is difficult to imagine that the other party investigated the murderer, which caused a crisis for the other party, and finally killed me and silenced me.

In other words, apart from determining the gender, is there any gain?

At this point, the intelligence coordination has been completed, and the investigation of the murder case has been concluded around the direction of the "serial murderer".

"So that's what happened."

"Ah, my teacher Sunli!"

Feiyu was used to this. After all, he was a criminal, a mystery writer, and a rich man.

It was a very unpoetic name, and Luo Bi didn't know that the other person was her fan until she talked to him. When she learned that he was going to work hard with her, she took the initiative to sign up to act with her.

The two drove slowly to the Fungi Research Institute, and then picked up the researcher who had delayed contact.

"Changing knives? Is it a sense of ritual or a desire to collect?"

"That's wrong. Apart from this, there is no very important information."

"Ah, it must be something sent from England." Gosunli looked in the direction Tsukidate Jun was pointing and smiled.

When Feiyu and his wife returned to Kesouyan, some identification results that took time to wait were also released.

"Did you go down to the conference room on the eighth floor last night?"

But no one, even after taking a break, still clings to the case, and is even close to tracking down his own body step by step.

It must be said that everything after that is just speculation, so everything is connected from the end of that message.

Not only that, every victim has a different heart wound.

As expected, Feiyu was not disappointed when he heard Tsukidate Jun's words. Instead, he nodded and stood up and thanked: "No matter what, I'd better thank Teacher Tsukidate for your help."

So I'm curious to know what the contents of the letter are.

The first is the shoe prints collected from the site.

Tsukidate Jun shouted immediately before seeing the other party: "Teacher, his luggage has always been placed under the table like this. It hasn't been broken for a long time."

"He's bad. You are Luo Biruihua from Kesouyan."

However, the following pieces of evidence yielded little results, but the hair extracted from the clothes worn by the deceased was quite fruitful.

"It should be on the eighth floor of their conference room." Da Baibai recalled: "As for the time, it should have been last night."

When the white man thought of the condescending expression of the sender, his expression became more terrifying and ferocious.

In other words, the prisoner will change his knife every time he kills a person. "

The smallest characteristic that a prisoner should have is not being immersed in the arrogance of killing and having no way to extricate himself.

But I never thought that someone would actually see me when I was trying to silence the other party.

His breathing became calm again, and the ferocious look on his face gradually disappeared, as if he had never been special before.

“Post-criminal?”

But the specific species of plant spores is unclear.

Restoration of shoe prints, restoration of the shape of the murder weapon from corpse wounds, hair under clothes

"Yes, did you do anything to help me?"

Each piece of physical evidence was tested and analyzed, and soon Feiyu also obtained first-hand identification materials.

Therefore, I can naturally go to search together with criminals like Ayanooji Fumimaro, but if the local criminals have a "self-exclusion" mentality.

Before that, Jinxiu had been working as a detective, investigating the unsolved case.

Ayanodaoji Fumimaro said with a solemn expression: "The person in charge of that case two years later was Saruto Sawachichi, who was in the Investigation Division 1 at that time."

The male backstage man repeated it, waited for a moment and then said with a slow smile: "I found it, it's the branch president's meeting that the Communist Party of China has withdrawn from, right?"

Among them, the DNA identification results of the hair attached to the underside of Sarutobi's criminal hood were found to have no criminal record before being compared with the database.

"Those are the spores of shiitake mushrooms!"

Feiyu saw that the clues from scientific research could only go so far, and he was willing to continue to be idle, so he took the initiative to take over the task and went to the Fungi Research Institute.

It doesn’t mean that our speculations haven’t been completely confirmed before and after that case.

As they watched the two leave, the colleagues in the office gathered together and asked about Tsukidate Junlai.

Two years later, before I killed eight people and realized that I was not exposed to the risk, I directly chose to lie dormant in a high profile.

"These things have been here for a long time, please take them away as soon as possible." Yue Guan said with a bad temper.

Qingtian Yuhua introduced before bowing to the young researcher: "That is Hiyu Criminal from Tokyo."

Spores of certain plants.

Obviously, it is because the old people have been working hard and the opportunities are given to newcomers, and we have all taken over the lower-end and more technical scientific identification.

Looking up, I saw an aunt in the hotel was cleaning outside.

Before Feiyu went to Kyoto for scientific research, the items left at the scene had not yet been delivered to the victim, and all the researchers had finished and started busy.

In addition, there is hair wax attached under the hair. Unfortunately, it is a niche brand and there is no possibility of tracing it.

In a dark room.

Before the two people who were still chatting heard the noise, they subconsciously looked at the door and found a female researcher wearing glasses walking back.

"Ah, that's right. You left your watch outside their hotel." The big white man said in a grumpy tone.

In that case, the prisoner was able to stop in time and the prisoner was safe. "

None of the hairs belonged to the deceased, but to the eighth person. It was very unlikely that they were left by the murderer.

Before the pleasantries were over, Feiyu took out the information and handed it to the other party.

Boiling murderous intent was brewing in my heart, but I became more and more calm.

After Ayanodaji Fumimaro's words fell, all the criminals present were in an uproar, and soon they started talking loudly.

Seeing that Feiyu and the others were about to leave, Tsukidate Jun quickly got up and saw them off with a bad look on his face.

In order to clarify this point, a professional plant expert who studies fungi is needed.

But whether it's money or asking me to help with things, I can definitely tolerate threats like that.

As for Feiyu, he later went to Kesouyan.

However, Luo Bi has no family, so no matter how beautiful the other person is, it has something to do with her family.

"Co-Exit Branch Directors' Meeting, Kobe"

And without exception, they are all women in their twenties.

Next, we need to consider other possibilities, and we can't just continue investigating in that direction.

In addition to hair wax, we also detected another thing.

As for the shape of the murder weapon reconstructed from the wound under the victim, it was a slightly curved scimitar, which was quite strange.

After identification, the owner of the hair is an adult woman with type A blood, and DNA identification is now being carried out.

"Is that so?"

If it can definitely be found, this is not an important clue to the case. "

The big white man rolled his eyes and slowly stepped back into the hotel.

In that dark room, the big white man sat behind the table and opened a letter.

"Ah, yes, yes, yes, it's not that meeting." Before the big white man heard the message from the male backstage, a sinister smile appeared on his lips.

The rays of sunlight receded, giving the entire room a dark tone.

Either one is likely to inspire admiration.

Everything can be connected naturally, and the scene is full of experienced criminals, so there is no need to say that.

I slowly left the hotel, and the white man walked to the phone booth in the corner and dialed the backend of the hotel.

Ayanokouji Fumimaro said with a solemn expression: "Besides this, there is another point. No matter whether it was before or this time, no murder weapon was found.

"Bad, bad, you know."

"The murderer was not caught at that time, so it is very likely that he is the same person as this time."

After saying that, the big white man hung up the phone directly.

But my excitement lasted only a moment.

As the criminal responsible for that case, Sarutō Sawachichi has been thinking about it even though it has not been solved.

Without the target, the efficiency of the search can be reduced by any amount, which can be regarded as a small or big breakthrough.

Before the complicated self-introduction, Feiyu also knew the other person's name, Qingtian Yuhua.

There was a little bit of bad curiosity in my eyes.
