Chapter 868 Capturing the Prisoner
  Being able to catch Kurosawa Tomoyo is actually a good result.

At least it can curb the subsequent arson cases.

At the same time, it also helped Tangze eliminate a layer of "smoke bombs" surrounding the murder case.

After eliminating the smoke bomb, Tang Ze began to sort out the case based on an ordinary judgment of murder, arson, and destruction of corpses.

In this way, he can objectively judge all clues to the greatest extent possible.

So he asked Uye Naoki to bring the information on the arson case, and then confirmed one thing.

In the two cases that Kurosawa Tomoyo denied, the ignition device used was an electric stove, and both were the same type of electric stove.

If you add the case of Kiriko Kodanagi, there are similarities between the three cases.

After Karasawa informed Naoki Kamei of this situation, when he saw the burned black electric stove in the photo, he couldn't help but be surprised: "Why are they all this wireless stove?"

"Look, this electric stove was burned in the warehouse of this IT company." Karasawa pointed to the content on the document: "In other words, it is not connected to the socket."

"Did the prisoner use the residual electricity in the circuit to turn on the electric stove and then use it as an ignition point to commit the crime?"

Hearing this, Uye Naoki speculated: "But this is a bit strange. How did the prisoner know that the heater had electricity."

"Do you think only someone turned on the electric stove?" Tang Ze clicked on the information and said: "I think something turned on the stove automatically and caused the fire."

"Eh? Open automatically?" Naoki Ueijing said in surprise: "But how is it possible..."

"Why isn't it possible?"

Tangze clicked on the black electric stove in the photo and said, "Don't forget, this is the latest design.

And since there is no experience from others, there may be defects, right?
  Don’t forget what kind of person Koyanagi Tsutoko is. "

"Senior, are you saying that Kiriko Koyanagi has been staying late at the union office recently just to investigate the defects of this heater!?"

After hearing what Karasawa said, Naoki Uyei quickly reacted and understood what Karasawa meant: "Then, the senior executives of the company are very suspicious!"

"Let's not talk about this for now. We need to find evidence of Koyanagi Tsutoniko's investigation to truly prove this."

Karasawa asked Naoki Kamei to go to the Forensic Section to collect the physical evidence collected by the union office, focusing on the paper materials.

However, because of the fire, most of these paper materials were burned to pieces, and more of them turned into fuel for the flames after the fire.

But even so, there is still a tall pile of paper left.

"Senior, what we are looking for is the deceased's record of investigating the electric furnace. But was this record recorded or was it simply destroyed in the fire..."

Naoki Uyei was rummaging through documents while maintaining a pessimistic attitude towards the work at hand.

"No, it's not as troublesome as you think. You overlooked a very crucial point."

Karasawa said: "Yamashita I also said before that Koyanagi Tsutoniko has been taking a ride home recently, which is a bit unusual."

"So we are still looking for an invoice?" Naoki Uyei said and found an invoice among the documents he was looking for.

"It's an overtime invoice named Kamijose." Naoki Kamei looked at it and said, "It's from Smooth Transportation Company, not the deceased."

"I found one here. It's from the same company as the one you have." Tang Ze shook the invoice in his hand.

The two of them rummaged around and quickly screened out the recent taxi invoices of Koyanagi Tsutoni and discovered the problem.

Those are the invoices issued by these taxis, each one issued by a different taxi company.

This is very strange. Karasawa and the two also looked for other people's taxi invoices, but found that all of them combined did not have as many taxi invoices as Kodanagi Tsutoni's.

Of course, this completeness does not refer to anything else, but to the taxi company's invoice.

Smooth Transportation Company, Tongxing Transportation Company, KM Wireless, and Boat Song Transportation Company.
  Invoices issued by various transportation companies were included, and because they all had dates, the two quickly arranged in order the vehicles the other party had taken during this period.

Unfortunately, these invoices were only up to the day before the incident. It is not clear which transportation company's taxi Kodanagi took on the day of the incident.

However, no physical evidence could be found, and the two of them still had witnesses to this method.

So Karasawa and the two went to the company again with the taxi receipt from Koyanagi Tsutoni and visited Yamashita I and Harada Makoto.

"Ms. Koyanagi Tsu has been taking a different taxi every night recently. Which company was the taxi from on the day of the fire?"

Spreading various invoices on the coffee table, Tang Ze explained the purpose of his visit to the two of them.

"I remember...it seemed like there was a rental of "Captain Riding the Wind" that night." Harada recalled after hearing Karasawa's words.

"It's a different rental company again..." Tang Ze nodded clearly, a light flashing in his eyes.

"This should be your company's taxi invoice, right?" Takagi said and picked up an invoice: "I think except for Ms. Koyanagizu, most of you use this taxi company with smooth traffic."

"Yes, our company cooperates with Smooth Traffic. Under normal circumstances, we only rent out Smooth Traffic."

"I understand." Tang Ze nodded, stood up and said goodbye to the two of them.

Although this visit was short, it completely confirmed Tangze's speculation.

"Senior, is there any connection between the taxi and this arson case?" After getting in the car, Uye Naoki vaguely felt that he had caught something, but he could not connect it.

"Think about it carefully." Tang Ze smiled slightly: "This is a key clue."

"I understand." After knowing that this was Karasawa's test, Naoki Kamei breathed a sigh of relief.

This also proves that Tangze Criminal has seen through the truth of the case and even found the prisoner, and then he will test himself.

So while rushing back, Naoki Ueijing's brain started to think separately.

However, until halfway through, Naoki Kamei still had no idea. As he sighed, he subconsciously glanced out the window, wanting to see how long he would have to think.

"Eh? Senior, this doesn't seem to be the way back to the Metropolitan Police Department, right?" Uekai Naoki glanced at the scene on the roadside and quickly reacted: "Is it from the Department of Science and Technology?"

"That's right, do you have any idea over there?" Tang Ze asked with a smile while driving.

"I didn't think so before, but now I seem to understand."

When Naoki Kamei realized that Karasawa was planning to return to science and research, and realized that the other party might be conducting experiments, he immediately thought of the connection between taxis and electric furnaces.

"Oh? Tell me." Tang Ze said with a smile.

"It's the radio, right?" After all, Naoki Uyei is also the chief of Karasawa's next term. He has good abilities, and during the time he joined the job, he was either with Karasawa or working with Takagi to solve the case involving Mouri Kogoro. .

It can be said that under such high-intensity cases, Naoki Uyei has gradually become a qualified criminal.

Of course, the reason why he didn't lie down was because of the ideas that Tang Ze had instilled in him since he joined the company. Otherwise, this guy would have become a tool.

After hearing Uye Naoki's thoughtful answer, Karasawa nodded with satisfaction.

Then the two of them came to Kesouyan and brought two things from Hiroshi Saito that the other party had already prepared.

Wireless stoves and intercoms produced by Air Electric.

"Then let's start testing."

Karasawa nodded towards Hiroshi Saito, who unplugged the wire from behind the electric stove and placed it on the table.

After that, Hiroshi Saito turned on the intercom and began to adjust the frequency of the intercom.

After adjusting to a certain frequency, the intercom placed on the table automatically turned on without anyone touching it.

"So what Kurosawa Tomoe said is true. The three arson cases were not committed by the other party, but because of the radio frequency of the walkie-talkie?"

After confirming his guess, Uye Naoki clenched his fists, as if he was happy that he had found the answer.

"Yes, I think Koyanagi Tongko also discovered this, so she stayed at night to experiment."

Karasawa said: "You must know that the intercom frequency of each taxi is different. The other party takes a different taxi, and it is also to test which taxi company's frequency this electric furnace will respond to."

As a person who lived in an era where technology continued to advance in his previous life, Tang Zeke had a much broader vision than people in this backward era.

Wireless stoves may be the latest innovation nowadays, but to Karasawa they are a commodity that can be seen everywhere.

In the future, the next software on the mobile phone will turn on the air conditioner, so combined with the fact that Kiriko Kodanagi has been coming home late recently, Karasawa quickly determined that the intercom in the taxi might be causing the problem with the heater.

"What kind of radio wave is that? Does it correspond to the radio frequency zone of wireless taxis?" Naoki Uyei quickly looked at Hiroshi Saito.

"Before you came, I had already done experiments, and after comparison, I found this company."

Hiroshi Saito took out a table listing the intercom frequencies of various companies. After comparing it with the frequency on the intercom screen, he found that this frequency was consistent with the frequency of the rental company "Captain Riding the Wind"!
  "This...this is the taxi that Koyanagi Tsutoniko took the night she was murdered!"

After Naoki Kamei saw the rental company with the corresponding frequency, he was stunned and said: "Then the death of Kiriko Koyanagi is an accident..."

As soon as he said this, Naoki Kamei shook his head and denied this statement: "No, it was obviously Ms. Koyanagi Tsu who had prepared the fire extinguisher in advance. It is impossible for the other party to be buried in the sea of ​​​​fire...

So fire and homicide cases should be separated!
  After Koyanagi Tsutoniko was killed, the taxi called also came to the downstairs of the company.

And it happened that the intercom frequency of the "Captain Chengfeng" called today was able to turn on the furnace switch, so an ordinary murder case was added to the arson case. "

"The analysis is good. This is the basic situation."

Karasawa nodded, "The remaining two arson cases have now been accounted for. Let's tell Gongchang Police Department later and ask him to contact the relevant departments to investigate "Al Electrical Appliances"."

"It's just senior, so the murder of Koyanagi Tsutoniko has become more confusing again."

Uye Naoki said with a serious expression: "Those people at the top of the company all had the motive to kill the deceased in order to keep this scandal secret."

"No, the prisoner has been exposed unintentionally." Tang Ze smiled and said, "Let's invite him over next."

.........

In the interrogation room, a young man in a suit looked at the two people in front of him uneasily: "Um...did I do something?"

"Mr. Harada, I think you should know the most about this, right?" Tang Ze looked at the young man in front of him and smiled slightly: "Since you are invited here, you should actually have some guesses, right? "

"You suspect that I am a prisoner!?" Harada was a little shocked and angry after hearing Karasawa's words: "How is this possible..."

"Do you still remember what you said when we got the invoice?"

Karasawa directly interrupted Harada's words and asked the other party.

"I said that the taxi that President Koyanagi Tsu took that night was a "Captain Riding the Wind". Is there any problem?"

Harada Zhen repeated what he said that day, but there was still a look of confusion on his face.

"It seems you haven't realized the problem yet."

Tang Ze looked at the other party and said, "We asked you about the timeline of the day when the crime occurred, and asked you and Mr. Ishita about it.

Then both of you said that you went home after get off work and never came to the union office.

However, we contacted the taxi company "Captain Chengfeng" and learned from the driver that the taxi that Ms. Koyanagi Tsu called was close to early in the morning, but she did not get in the taxi in the end.

Because she was killed before she even got into the car. "

Looking at Harada Makoto, whose face was pale and his pupils were beginning to tremble, Karasawa stood up and leaned forward, looking down at the young man in front of him with sharp eyes like knives, and said word by word:

"In other words, only those who were still in the company at the time knew that Ms. Koyanagi Jin called the Captain Wind Taxi!"

Karasawa's questioning made Harada's body tremble even more. Seeing this, Naoki Kamei slapped the table and shouted: "That night, you were with Ms. Koyanagi Tsu, but you hid this fact!

In the end what happened! ! Did you kill Kiriko Kodanagi? ? "

"I…"

Harada shivered immediately after being hit like this, but he quickly calmed down.

Harada Zhen slowly lowered his head and looked at the ring in his hand, his face showing a complicated expression that seemed to be smiling and crying. There were memories and sweetness in it, but more of it was still pain...

But with a hint of relief, Harada really told everything that happened that night.

Although Kiriko Koyanagi is rumored to be an older woman in her forties who has not yet started a family, she actually already has a lover.

And that lover was him who had only been in the company for two years.

Because they were in the same company and there was a big age difference between the two, they maintained an underground romance.

Originally everything was wonderful, but things have taken a turn for the worse recently.
