Gongchang Police Department's speculation is not unreasonable. After all, the arsonist's method is to use a heater to set the fire.
Although the furnace catches fire in an instant, it will make it impossible for unprepared people to put it out, but it is limited to this, and it will not cause a secondary explosion or other violent combustion environment.
In other words, even if manpower cannot extinguish it, it is still no problem to escape directly. This is also the reason why there were no casualties in the previous few times.
So this situation is very intriguing. Because the deceased is dead, people have to wonder whether the fire was deliberately set to kill people.
"Vendetta..."
After hearing this, Police Officer Megure said in a deep voice: "It seems that we need to conduct a key investigation on the customers and employees of the company "Al Electric" to see if anyone has a grudge against Koyanagi Tsutoni."
"The previous investigation direction cannot be completely abandoned."
Karasawa made a simple psychological profile of the criminal who committed the arson case, and then said: "In addition to customers and employees, people who have not become employees must also be investigated. Compared with the previous two types of people, perhaps this kind of people
People are more likely to be motivated.”
"Well...it does make sense, then let's proceed with the two lines at the same time!"
Officer Megure pondered for a moment and then nodded, looking at the Gongchang Police Department: "You were responsible for investigating the previous companies, so I have to trouble the Gongchang Police Department to continue the investigation.
We are mainly conducting investigations based on the interpersonal relationships of the deceased, Kiriko Koyanagi. After all, the situation is still unclear and there are various possibilities."
After simply assigning the direction of the subsequent investigation, Tang Ze once again focused on the fire extinguisher.
"Tang Ze Criminal, I saw you were looking at the fire extinguisher just now. Did you find anything strange?"
Uye Naoki, who was quietly listening to the speculations of several people, noticed Karasawa's actions and couldn't help but ask.
After all, based on his understanding of Tang Ze's crime, there must be a reason why the other party cares so much about fire extinguishers.
"Well, I just felt something strange when I took a quick look at it, but now I've discovered a problem."
Tangze nodded and approached the burnt fire extinguisher, pointing to the flexible pipe of the fire extinguisher hanging on the ground: "Normally, when the fire extinguisher is stored, the hose is fixed, right?
But for the fire extinguisher next to the heater, not only the hose has been removed, but the safety fan has also been turned on.
Do you think that if a fire extinguisher like this is placed next to the stove, it will be picked up in a hurry?
We have already reached this point, but there is no dry powder sprayed by the fire extinguisher in the room. Isn’t it a little abnormal?”
"Ah, it is indeed..."
After hearing Tang Ze point out what was wrong, the group also realized what the problem was.
"If you pick up the fire extinguisher in a panic after a fire breaks out, it is normal to hold the fire extinguisher even when you are burned to death."
Police Chief Gong of the Fire Department made this judgment based on his own experience, “After all, people want to grab the last straw to survive before they die.
And regardless of whether this fire extinguisher was useful for the food at that time, it would not have been thrown aside by the deceased."
"That means that this fire extinguisher was prepared before the fire broke out?" Takagi subconsciously came up with the reasoning after hearing the two people's reasoning.
"Yeah, it seems like we knew in advance that there would be a fire."
A glint flashed in Tang Ze's eyes: "I knew clearly that a fire might break out and even made preparations, but I was burned to death...
No, was she really burned to death?"
"It's so foggy. Is there any way to cover this up with ordinary murders and arson..."
Hearing Karasawa's reasoning, Officer Memu felt a little headache and said, "How about I leave the investigation in this direction to you, Karasawa Criminal Investigation?
We are working in three directions at the same time to solve the case as soon as possible. Now many people have expressed dissatisfaction and feel that their safety is not guaranteed."
Think about it, four cases were committed in two days, and this case tonight even killed someone. You can imagine how dissatisfied the people will be after the media broadcast this news.
The troops were divided into three directions, and it was a helpless move to start the investigation in three directions. After all, each direction may lead to the truth, and they could not give up any possibility now that they were racing against time.
But it was useless no matter how anxious he was. After bidding farewell to Officer Megure and Police Yumaga, Karasawa did return home and rest directly.
There was no way, both of them had a large number of personnel to investigate in their respective directions, but Tangze regarded the case as an ordinary murder case.
But it was too late now, and there was no way to start the investigation, and he also needed a demonstration report to make a preliminary judgment on whether his speculation was necessary.
Early the next morning, Karasawa received from his subordinates the autopsy report that Aso Minoru had worked overtime to complete.
According to the results of the autopsy, the cause of death was suffocation.
However, because the damage to the corpse this time was relatively serious, with the head, neck and half of the body burning, it was impossible 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 seemed to be correct. After the other party was actually killed, the prisoner lit the fire in order to destroy the scars on his neck and blame the serial arsonist.
Not only because of the autopsy report, but also because of the position where Kiriko Kodanagi fell.
Generally speaking, when a fire breaks out, people will always stay away from the fire point.
But after Karasawa looked at the photos of the crime scene, he discovered that the place where Koyanagi Tsutoniko fell was very close to the fire point, which is why her body was so badly burned.
But if that's the case, shouldn't there be signs of struggle?
You must know that being burned by fire is a very painful thing, but when Koyanagi Tsutoniko was dying, she did not make any movement. This is obviously a problem.
Now that he has questions, all he has to do is to unravel these unnatural places at the crime scene and restore the truth of the case.
Because Officer Megure is responsible for investigating the interpersonal relationships around Koyanagi Tsutoni to see if there are any grudges with others in life or work, there is naturally no need for Karasawa to conduct additional investigations in this regard.
So after reading the autopsy report, he took Uye Naoki to the "Al Electrical" company where Koyanagi Tsutoniko worked.
.......
"Fire extinguisher?"
After the two subordinates who met Koyanagi Tsutoni introduced themselves briefly, Karasawa took the lead in asking about the things he was concerned about.
"Yes, I wonder where the fire extinguisher is usually placed?" Tangze nodded and asked again.
"In the nearest corridor." Yamashita answered with glasses and a crew cut.
"That's right."
Karasawa nodded without saying anything, and immediately looked at the two of them and asked, "I wonder if Ms. Koyanagi Tsu has done anything different from usual in recent times?"
"A different place..."
Harada Makoto, who looked younger on the side, scratched his head and said: "Speaking of which, she has always been the last to leave in recent times.
I leave by taxi every night.”
"Every night?"
Hearing Harada's true words, Karasawa raised his eyebrows.
This is indeed an unusual thing. Maybe taking a taxi is not a big deal in other countries, but the cost of neon taxis is very high.
Being able to take a taxi home every day can be considered a luxury benefit for a company.
"Can you tell me more about it?"
After Naoki Ueijing heard what the man said, he naturally realized that something was wrong, so he continued to ask: "Since you go back so late, you must be working overtime. What exactly do you do?"
"This... we don't know what to say."
Yamashita adjusted his glasses: "The union has not been so busy recently, and we don't know why the president stays here every day..."
"Don't you come here often?" Tang Ze asked doubtfully.
"Because this is the office of the labor union, the daily work is not actually here." Harada explained: "Normally, our employees only come here on Mondays."
"Is that so?" Tang Ze nodded and looked at the two of them and said, "Just in case, did you two come here yesterday?"
"No."
"I'm not coming either."
The two men shook their heads, indicating that they went home directly after get off work and did not come to the guild.
"Really...but Ms. Koyanagi Tsu actually stays here every night..." Karasawa walked back and forth thinking, "What on earth are you doing...?"
"Maybe as the president of the union, there are some things that only she can handle." Harada said.
"Guild President..." Karasawa murmured twice, then looked at the two of them and said, "I wonder if there are any promotional materials about Ms. Koyanagi Tsu? I would like to read them."
"some."
Yamashita nodded: "I'll get it. Harada, please take the two criminal gentlemen to the reception room first. It's not good to stand here all the time..."
"I understand, Yamashita-senpai." Young Harada nodded, stretched out his hand towards the two of them and said, "Please follow me."
The three of them walked from the burned-out union office to the reception room. Looking at the decorations as usual, the inexplicable feeling of depression from before also dissipated a lot from their hearts.
Harada's expression was visibly relaxed after arriving at the crime scene. Obviously, talking at a crime scene is still a bit stressful for ordinary people, especially when the other party is an acquaintance of one's own.
But this is also human nature,
"This is it."
The three of them sat on the sofa chatting and waited for a few minutes. Yamashita handed over a company brochure.
Because the other party had already turned to the page where Ms. Koyanagizu was, Karasawa easily read the information in the manual after taking it.
Of course, this was not the purpose of Karasawa asking for the manual, he just wanted to use this to let the two of them reveal more information.
"It says here that Ms. Koyanagi Jin was nominated as a candidate by herself?"
Tang Ze looked at the information and found one of the points to start the topic.
"Because President Koyanagi Tsu is a person with a strong sense of justice." Harada Makoto smiled after hearing this: "And he also has a strong execution ability, and is even called the "Iron Lady"."
"Perhaps it's because I'm still single, so I don't have any burdens." When Yamashita said this, he and Harada smiled at each other, as if the mere mention of it was something that would make people smile.
"I am forty-two years old this year, but I have not been married once." Naoki Uyei 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, "It seems that I have gone on a blind date recently."
"A blind date?" Tang Ze raised his eyebrows: "At her age..."
Tang Ze deliberately did not finish what he said, but left the second half. This kind of open blank topic will also allow the other party to say what he wants to say.
As expected, Harada heard what Karasawa said and laughed: "I heard that Chairman Koyanagi Tsu had no idea about this at first, but he was persuaded by people in the company later."
"Haha... You two seem to know President Koyanagi Tsu very well." Naoki Uyei smiled and made a test sound quietly.
It has been so long since he joined the company and he has handled so many cases with Karasawa that Naoki Kamei is no longer the cute little rookie he was before. He has also learned a lot from various cases.
For example, you can use a language that is slightly "over the line" to test the other person and see the other person's attitude. If the other person is very sensitive in this regard, then 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 step forward and act as a peacemaker to ease the emotions between the two parties.
It's a pity that this method doesn't work every time. At least the two people in front of me didn't feel the slightest offense.
"That's because she's a celebrity."
Faced with Uami Naoki's question, Yamashita smiled and explained.
"Celebrity? Because she is the president of the guild? Or is she older and unmarried?" Tang Ze asked.
"No, none of them." Yamashita shook his head: "It's because the union's activities have exceeded the original limits."
"Can you tell me in detail?" Tang Ze asked.
"The duty of the union is to ensure the benefits that employees deserve, but the president even interferes in other affairs to find trouble."
Yamashita explained: "For example, if you are not satisfied with the company's products, you don't need this function or the style is not good.
It can be said that he is completely the complaint specialist within the company.”
"Well... I guess he is enthusiastic about his work." Harada seemed to calm down after hearing his senior's words.
"But her self-righteousness is annoying."
After hearing Harada's words to smooth things over, Yamashita seemed to blurt out his true feelings out of instinctive disgust.
"Oh? Are you hated?" Naoki Uye's eyes immediately became sharp after hearing what Yamashita said.
Yamashita was suddenly startled, and when he turned to look at Uami Naoki, he realized that he had made a mistake. He rubbed his hands with a somewhat unnatural expression, and finally said slowly: "Actually, Koyanagi is an annoying guy..."
"What?"
Uye Naoki leaned forward, startling Yamashita I. He quickly explained: "I didn't say that, it was a rumor from the company..."
