Detectives of Detective World

Being able to catch Kurosawa Tomoshi is already a good result.

At least it can curb the continuous occurrence of arson cases.

At the same time, it also helped Tang Ze eliminate a layer of "smoke bombs" that shrouded the murder case.

After excluding the smoke bombs, Tang Ze began to sort out the case with an ordinary judgment of murder, arson and destruction of corpses.

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

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

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

If the case of Kiriko Koyanagizu is added, the three cases have similarities.

After Tang Ze informed Naoki Uejing of this situation, when he saw the blackened electric stove in the photo, he couldn't help but wondered: "Why is it all this wireless stove?"

"Look, this electric stove was burned in the warehouse of this IT company." Tang Ze pointed to the content on the information: "That is to say, there is no socket connected."

"Did the criminal use the residual electricity in the circuit to turn on the electric furnace, and then used it as an ignition point to commit the crime?"

Uejing Naoki speculated after hearing the words: "But it's also a bit strange, how did the prisoner know that the heater has electricity?"

"Do you think that only someone turned on the electric stove?" Tang Ze clicked on some information and said, "I think something turned on the stove automatically, causing the fire."

"Eh? Automatically open?" Naoki Uesi said in surprise, "But how is it possible..."

"Why is it impossible?"

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

And since there is no previous experience, there may be defects, isn't it?

Don't forget what kind of person Koyanagizu Kiriko is. "

"Senior, do you mean that Xiao Yanazu Kiriko came home late from the trade union office recently, just to investigate the defects of this heater!?"

Umi Naoki also reacted quickly after hearing Tang Ze's words,

I understood Tang Ze's meaning: "In that case, those high-level executives of the company are very suspicious!"

"Let's not talk about that, we need to find evidence of Koyanagizu Kiriko's investigation to really prove this point."

Tang Ze asked Shangjing Naoki to examine the physical evidence collected by the Kona trade union office, focusing on those 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 very high pile of paper left.

"Senior, what we are looking for is the record of the deceased investigating the electric furnace, but has this record been recorded or was simply destroyed in the fire..."

Umi Naoki was looking for documents while holding a pessimistic attitude towards the work at hand.

"No, it's not as troublesome as you imagined. You've overlooked a very important point."

Tang Ze said, "Yamashita also said before that Kiriko Koyanagizu has been taking a ride home recently, which is a bit unusual."

"So we still need to look for an invoice?" Uesi Naoki said and found an invoice among the documents he was rummaging through.

"It's an overtime receipt called Kamijoze." Naoki Uesai looked at it and said, "It's from Shunli Transportation Company, not from the deceased."

"I found one here, and it's from the same company as the one in your hand." Tang Ze shook the invoice in his hand.

The two kept searching, and quickly screened out the invoices of Tongzi Xiaoyanagijin's recent taxi ride, and found the problem.

That is the invoice issued by these taxis, each issued by a different taxi company.

This is very strange. Tang Ze and the others also found other people's taxi receipts, only to find that the sum of everyone's taxi receipts was not as complete as that of Little Liujin Tongzi's taxi receipts.

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

Shunli Transportation Company, Tongtong Transportation, KM Wireless, Chuange Transportation Company...

The invoices issued by various transportation companies were included in it, and because there were dates on them, the two quickly arranged the vehicles that the other party took during this period in order.

Unfortunately, these invoices are only up to the day before the incident, and it is not clear which transportation company's taxi Koyanagizu Koko took on the day of the incident.

However, no physical evidence can be found, and the two still have witnesses to this method.

So Tang Ze and the two of them went to the company again with the invoice for Koyanagizu Kiriko's taxi ride, and visited Yamashitai and Harada Makoto.

"Ms. Koyanagitsu has been taking a different taxi every night recently. May I ask which company was the taxi on the day of the fire?"

Spreading all kinds of invoices on the coffee table, Tang Ze explained the purpose of this visit to the two.

"I remember...that night it seemed to be a taxi from "Captain Riding the Wind." Makoto Harada recalled after hearing Tang Ze's words.

"It's a different rental company again..." Tang Ze nodded knowingly, a gleam flashed in his eyes.

"This should be your company's taxi invoice, right?" Takagi said this and picked up a receipt: "I see that except for Ms. Koyanagitsu, most of you take taxis from this smooth traffic taxi."

"That's right, our company cooperates with Shunli Traffic, and generally only rents out Shunli Traffic."

"I understand." Tang Ze nodded, got up and bid farewell to the two.

Although the visit this time was short, it completely confirmed Tang Ze's speculation.

"Senior, is there any connection between the taxi and this arson case?" After getting into the car, Umi Naoki faintly felt that he had caught something, but he couldn't connect it.

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

"I see." Knowing that this is Tang Ze's test, Naoki Uesi heaved a sigh of relief.

This also proves that criminal Tang Ze has seen through the truth of the case and even found the criminal, so he will test himself.

So in the process of rushing back, Naoki Uesi's brain started to work separately and began to think.

It's just that until halfway, Naoki Uesi still had no clue. When he sighed, he subconsciously looked out the window, wanting to see how much time he still had to think.

"Eh? Senior, this doesn't seem to be the way back to the Metropolitan Police Department?" Umi Naoki glanced at the scene on the side of the road, and quickly reacted: "Is it from Kesouyan?"

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

"I didn't have it before, but now I seem to understand."

When Naoki Uesi realized that Tang Ze was planning to return to Kesouyan, and realized that the other party might be doing an experiment, he immediately thought of the connection between the taxi and the electric furnace.

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

"Is it the radio?"

After all, Naoki Uesi is also the chief of Karazawa's next term, and he has good abilities, and during the period of joining the job, he either stayed with Karazawa or worked with Takagi to solve the case of Mori Kogoro.

It can be said that under such high-intensity cases, Naoki Uesi 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 job, otherwise this guy would have become a tool man.

Tang Ze nodded in satisfaction after hearing Naoki Uekai's thoughtful answer.

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

Radio stoves and intercoms produced by Aire Electric.

"Then, let's start the experiment."

Tang Ze nodded towards Saito Hiroshi, who unplugged the wire behind the electric stove and put it on the table.

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

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

"So what Kurosawa said is true, the three arson cases were not done by the other party, but because of the radio frequency of the intercom?"

Uejing Naoki shook his fist after confirming the guess, as if he was happy to find the answer.

"That's right, I think Koyanagizu Tongko also discovered this, so she stayed to experiment at night."

Tang Ze said: "You must know that the intercom frequency of each taxi is different. The other party takes different taxis to test which taxi company's frequency the electric stove will respond to."

As a person who lived in an era where technology was constantly advancing in his previous life, Tang Ze had a much broader vision than people in this backward era.

The wireless stove may be the latest innovation now, but for Tang Ze, it is 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 abnormal late return of Koyanagi Tsu Kiriko, Tang Ze quickly judged that the intercom in the taxi may have caused the heater to have a problem.

"What kind of radio wave is that, corresponding to the radio frequency zone of the wireless taxi?" Umi Naoki looked at Saito Hiroshi quickly.

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

Hiroshi Saito took out a table listing the intercom frequencies of various companies, and compared it with the frequency on the intercom screen, he found that this frequency was consistent with the frequency of the rental company "Captain Wind"!

"This... this is the taxi that Kiriko Koyanagizu was killed on the night she was killed!"

After seeing the rental company with the corresponding frequency, Naoki Uejing said in astonishment, "Then, the death of Kiriko Koyanagitsu was an accident..."

As soon as he said this, Naoki Uesi shook his head and denied this statement: "No, the fire extinguisher was obviously prepared by Ms. Koyanagitsu in advance, and the other party could not be buried in the sea of ​​flames...

So fire and homicide cases should be separated!

After Koyanagizu Kiriko was killed, the taxi she called also came downstairs to the company.

And it just so happened that the intercom frequency of "Captain Riding the Wind" that was called today could turn on the heater, and this allowed an ordinary murder case to be added to the arson case. "

"The analysis is good, and the basic situation is like this."

Tang Ze nodded, "The remaining two arson cases have now been explained, let's tell the Gongchang police department later, and ask him to contact the relevant department to investigate "Aier Electronics."

"It's just senior, so the case of Xiao Liujin Tongzi's murder has become blurred again."

Uejing Naoki said with a serious expression: "The people at the top of the company have the motive of killing the deceased in order to keep this scandal a secret."

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

………

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

"Mr. Harada, I think you should be the clearest 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 guessed, right? "

"You suspect that I'm a criminal!?" Harada was a little shocked when he heard Tang Ze's words: "How is this possible..."

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

Tang Ze directly interrupted Harada Makoto and asked the other party.

"I said that the taxi Chairman Koyanagitsu took that night was "Captain Riding the Wind". Is there any problem?"

Harada repeated what he said that day, but his face was still blank.

"It seems you haven't realized what the problem is."

Tang Ze looked at the other party and said, "We asked you that day, about the timeline of you and Mr. Inoshita on the day when the incident happened.

Then both of you said you went home after get off work and never visited the union office at all.

But we contacted the taxi company "Captain Riding the Wind" and learned from the driver that the taxi called by Ms. Koyanagitsu was close to midnight that day, but we didn't get in the taxi in the end.

Because she was killed before getting into the car. "

Looking at Makoto Harada, whose face was pale and his pupils began to tremble gradually, Tang Ze stood up and leaned forward, looking down at the young man in front of him with sharp eyes like knives:

"That is to say, only those who were still in the company at the time knew about Ms. Koyanagitsu calling the "Captain Riding Wind" taxi!"

Tang Ze's questioning made Harada's body tremble even more, Naoki Uaijing saw the slap on the table and shouted: "That night, you were with Ms. Koyanagitsu, but you concealed this fact!

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

"I…"

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

Makoto Harada slowly lowered his head, looked at the ring in his hand, his complexion showed a complex expression of smiling and crying, there were memories, sweetness, but more pain...

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

Although Xiaoyanagijin Tongzi is rumored to be an older woman in her forties who has not yet married, in fact she already has a lover.

And that lover is him who has only been in the company for two years.

Because they are in the same company, and the age difference between the two is too large, they have always maintained an underground relationship.

All of this was originally beautiful, but things have taken a turn for the worse recently.
