Detectives of Detective World

The police department's speculation is not unreasonable, after all, the arsonist's method is to set fire with a stove.

Although the stove catches fire in an instant, people who are not prepared will not be able to put it out, but it is limited to this, and it will not cause a violent combustion environment such as a secondary explosion.

In other words, even if there is no way to put out the manpower, there is no problem in escaping directly, which is why there were no casualties in the previous few times.

So this time the situation is very intriguing, because the deceased is dead, so people have to think more about whether the fire was deliberately set to kill.

"Vengeance?"

Officer Mumu pondered after hearing the words: "It seems that we will focus on investigating the customers and staff of the company "Aier Electric" to see if anyone has a grudge against Koyanagi Tsutoko."

"The previous investigation direction cannot be completely abandoned."

Tang Ze made a simple psychological profile of the perpetrator of the arson case, and then said: "In addition to customers and staff, people who have not become staff should also be investigated. Compared with the previous two types of people, perhaps this type of People are more likely to be motivated.”

"Well... it does make sense, then let's do both lines at the same time!"

Officer Mu Mu pondered for a moment, then nodded and looked at the Chief Gong Police Department: "You are in charge of the investigation of the previous companies, and you have to trouble the Chief Gong Police Department to continue the investigation.

We mainly investigate the interpersonal relationship of the deceased Koyanagizu Kiriko. After all, the current situation is still unclear, and there are various possibilities. "

After simply assigning the direction of the follow-up investigation, Tang Ze focused his attention on the fire extinguisher again.

"Criminal Tang Ze, I just saw that you have been looking at the fire extinguisher. Did you find something strange?"

Naoki Naoki, who was quietly listening to several people's speculation, noticed Tang Ze's actions, and couldn't help asking.

After all, based on his understanding of Tang Ze's criminal record, there must be a reason for the other party to care so much about fire extinguishers.

"Well, I just felt a little strange at first glance, but now I have found the problem."

Tang Ze nodded and approached the scorched black fire extinguisher, and pointed to the flexible pipe of the fire extinguisher sagging on the ground: "Normally, when the fire extinguisher is stored, the flexible pipe is fixed, right?

But this fire extinguisher next to the stove,

Not only has the hose been removed, but the safety fan has also been opened.

Do you think that such a fire extinguisher is placed next to the heater and is picked up in a hurry?

It has already been done to this point, and there is no dry powder sprayed by the fire extinguisher in the room. Is it a little abnormal? "

"Ah, indeed..."

Hearing Tang Ze pointed out something wrong, the group also realized the problem.

"If you pick up the fire extinguisher in a panic after a fire, it is normal to hold the fire extinguisher even when you are burned to death."

Chief Gong of the Fire Division made a judgment based on his own experience, "After all, people want to grab the last straw to survive before they die.

And whether this fire extinguisher was useful to the food at that time, it would not be thrown aside by the deceased at will. "

"That means, this fire extinguisher was prepared before the fire broke out?" Takagi subconsciously walked out of the reasoning after hearing the reasoning of the two.

"Yeah, it seems to have known in advance that there would be a fire."

Tang Ze's eyes flashed a ray of light: "Obviously, he knew that there might be a fire, and he even prepared for it, but he was burned to death...

No, was she really burned to death? "

"The fog is heavy, is there still ordinary murder and arson to cover up this line..."

Hearing Tang Ze's reasoning, Officer Mumu had a headache and said, "Then the investigation in this direction will be handed over to Tang Ze's criminal investigation?

We are working in three directions at the same time, and we need to solve the case as soon as possible. Now many people are expressing their dissatisfaction and feel that their safety cannot be guaranteed. "

Think about it too, 4 cases were committed in two days, and this case even killed people tonight. It is conceivable how dissatisfied the public will be when the news is broadcast by the media.

The soldiers were divided into three directions, and it was helpless to start the investigation in three directions. After all, every direction could lead to the truth, and now they could not give up any possibility in the race against time.

But no matter how anxious it is, it's useless. After saying goodbye to Officer Mumu and Chief Gong, Tang Ze did return home and rested directly.

No way, both of them have a large number of people who need to be investigated in their respective directions, and Tang Ze treats the case as an ordinary homicide.

And it is very late now, and there is no way to start an investigation, and he also needs a presentation report to preliminarily determine whether his speculation is necessary to proceed.

Early the next morning, Tang Ze got the autopsy report from his subordinates that Ma Shengshi had worked overtime overnight.

According to the results of the autopsy, the cause of Koyanagizu Kiriko's death was suffocation.

However, because of the serious damage to the corpse this time, the head, neck, and half of the body were burned in the eyes, and there was no way to tell whether the other party was suffocated by the smoke from the burning.

After seeing this piece of news, Tang Ze felt that his judgment did not seem to be wrong. The other party might have really been killed, and the prisoner lit the fire in order to destroy the scar on his neck and to blame the serial arsonist.

Not only because of this autopsy report, but also because of the location where Koyanazu Kiriko fell.

Generally speaking, when a fire occurs, people will always stay away from the fire point.

But after seeing the photos of the crime scene, Tang Ze found that Koyanagi Tsutoko fell very close to the fire, which is why her body was burned so heavily.

But if so, shouldn't there be signs of struggle?

You must know that being burned is a very painful thing, and when Koyanagi Tsutoko was dying, there was no movement at all. This is obviously a problem.

Now that he has doubts, all he has to do is to unravel these unnatural parts of the crime scene and restore the truth of the case.

Because the police officer Mumu is responsible for investigating the interpersonal relationships around Koyanagi Tsutoko to see if there is a grudge with others in life or work, it is natural that Tang Ze does not need to conduct additional investigations in this regard.

So after reading the autopsy report, he took Naoki Uei to the "Aier Electric" company where Koyanasu Kiriko was working.

......

"A fire extinguisher?"

After a brief self-introduction to the two subordinates of Koyanagi Tsutoko, Tang Ze took the lead in asking what he cared about.

"Yes, I don't know where the fire extinguisher is usually placed?" Tang Ze nodded and asked again.

"In the nearest corridor." Yamashita replied with glasses and a flat head.

"That's it."

Tang Ze nodded and didn't say much, then looked at the two and asked, "I don't know how Ms. Koyanagi is different from usual recently?"

"Different place..."

Maharaja Harada, who looked younger, scratched his head and said, "Speaking of which, the president has always been the last to leave recently.

We leave by car every night. "

"Every night?"

Hearing Harada's words, Tang Ze raised his eyebrows.

This is indeed a somewhat unusual thing, maybe taking a taxi in other countries is not a big deal, but the cost of neon taxis is very high.

And being able to take a taxi home every day is a luxury benefit for a company.

"Can you elaborate?"

After hearing the man's words, Naoki Uei naturally realized that it was abnormal, so he continued to ask: "Since I went back so late, it should be working overtime, right? What do you do?"

"This... we don't know what to say."

Yamashita adjusted his glasses: "The labor union hasn't been so busy recently, and we don't know why the president stays here every day..."

"Don't you come here often?" Tang Ze wondered.

"Because this is the union's office, the daily work is not actually here." Harada Ma opened his mouth to explain: "Usually our staff only come here on Mondays."

"Is that so?" Tang Ze nodded and looked at the two and said, "Just in case, did you two come here yesterday?"

"No."

"I didn't come either."

The two men shook their heads one after another, indicating that they went home directly after get off work and did not come to the guild.

"Really... But Ms. Koyanagi actually stays every night..." Tang Ze was thinking back and forth, "what is it doing...?"

"Perhaps as the president of the union, there are some things that can only be handled by her." Harada Ma said.

"Guild president..." Tang Ze murmured twice, then looked at the two of them and said, "Do you have any promotional materials about Ms. Koyanagi? I want to read it."

"some."

Yamashita nodded: "I'll get it, Harada, please take the two criminals to the reception room first, it's always a little bad to stand here..."

"I know Senior Yamashita." The young Harada nodded, stretched out his hand towards the two and said, "Please come with me."

The three of them came to the reception room from the burnt-out dark union office. Looking at the decorations as usual, the inexplicable feeling of depression before dissipated a lot from their hearts.

Being able to go to Harada Makoto was obviously relieved. Obviously, talking at the crime scene is still a little stressful for ordinary people, especially if the other party is still his acquaintance.

But it's also human nature,

"That's it."

The three did not sit on the sofa chatting and waiting for a few minutes. Yamashita handed over a company brochure.

Because the other party had already turned to the page where Ms. Koyanagi was located, Tang Ze easily read the manual after taking it.

Of course, this is not the purpose of Tang Ze asking for the manual, he just wants to let the two reveal more information through this.

"It says that Ms. Koyanagi nominated her own candidate?"

Tang Ze looked at the information and found one of the points to start the topic.

"Because President Koyanagi is a person with a strong sense of justice." Harada Ma smiled when he heard the words: "And the execution is also very strong, and she is also called "Iron Lady"."

"Perhaps it's because I'm still single, so I don't have any burden." Yamashita said this and Harada Ma said that they looked at each other and smiled, as if this itself was something that would make people smile.

"I'm forty-two years old this year, but I haven't been married yet." Naoki Uai looked at the information in his hand and read it out: "This is really..."

"Actually, this matter is actually well known in the company." Yamashita smiled and said, "I seem to have gone on a blind date recently."

"Blind date?" Tang Ze raised his eyebrows: "At her age..."

Tang Ze deliberately didn't finish his words, but left the second half, and this kind of open-ended blank topic will also allow the other party to say what he wants to say.

Sure enough, Harada Zhen heard Tang Ze's words and smiled: "I heard that President Koyanagi didn't have this idea at first, but was persuaded by the company's people later."

"Haha... The two of you seem to know President Koyanagi very well." Naoki Uei smiled and probed quietly.

It has been so long since he joined Tang Ze and he has handled so many cases with Tang Ze. Naoki Uai is no longer the little cute newcomer he used to be, and he has also learned a lot in various cases.

For example, use a language that is slightly "over the limit" to test the other party to see the other party's attitude, and if the other party is very sensitive in this regard, his next question will be more "mean" and straightforward.

Until the other party can't help but start to get angry, at this time Tang Ze will stand up and act as a peacemaker to ease the emotions between the two sides.

It's just a pity that this method is not always useful, at least the two people in front of them didn't feel the slightest offense.

"That's because she's a celebrity."

In the face of Naoki Naoki's question, Yamashita explained with a smile.

"Celebrity? Because she is the president of the guild? Or is she unmarried at an older age?" Tang Ze asked.

"No, not at all." Yamashita shook his head: "It's because the union's activities exceeded the original limit."

"Can you tell me in detail?" Tang Ze asked.

"The duty of the trade union is to ensure the benefits that the employees deserve, but the president, she even intervenes in other affairs to find fault."

Yamashita explained: "For example, you are not satisfied with the company's products, for example, you don't need this function or the style is not good.

It can be said that it is completely the complaints specialist within the company. "

"Well... it's considered to be enthusiastic about work." Harada seemed to make a round after hearing the senior's words.

"But her self-righteousness is annoying."

Hearing Harada's remarks, Yamashita seemed to blurt out his true feelings because of his instinctive disgust.

"Oh? Are you hated?" Naoki Naoki's eyes sharpened immediately after hearing Yamashita's words.

Yamashita was stunned for a moment. When he turned to look at Naoki Ukai, he realized that he had made a blunder. He rubbed his hands unnaturally, and finally said slowly, "Actually, Xiaoyanasu is a disgusting guy..."

"what?"

Naoki Kamijou leaned forward and shocked Yamashita, and he quickly explained, "I didn't say that, it's the company's rumor..."
