Friday, April 14, night, the scene of the incident in the mountains of Gunma Prefecture.

Under the light of the searchlights on the police car, the forensic officers were busy in the wind and snow, and Triangle said that he had no appetite for dinner, and sat back in the car alone.

Yamazaki and Mori were eating dinner, and whispered to the somewhat absent-minded Yamamura police officer what had happened, as well as some guesses and suggestions.

Officer Yamamura nodded and said, "It turned out that he killed him, but this matter, isn't it really a suicide?"

Yamazaki laughed: "Officer, before there is no evidence, he committed suicide." ”

Officer Yamamura smiled a little embarrassedly: "That's right, everything will be known when it is identified." ””

"Alright, let's go, if you want to eat supper, you have to work hard. Maori said angrily.

"Yes, Mr. Maori, you are so right. The police officer of the mountain village cheered up, reluctantly said goodbye to the hot pot, and went to assign the task.

At Yamazaki's suggestion, Mori also called the Yumi police officer in Tokyo and asked her to retrieve the video again to see the situation of the car that Tsutoshi Triangle was driving.

By the way, I returned the favor that asked her to help with the commission before, or transferred it to Officer Sato.

Officer Yumi will definitely inform Officer Sato of the incident and let her investigate, so as to increase Officer Sato's merits, and Officer Yumi has participated in the investigation before and after, and she can also get a little light. ……

Over time, some forensic results came out one after another.

According to the snow thickness data released by the meteorological department, as well as the thickness of the snow on the body and tires, it is speculated that the vehicle has been parked in the snow for 11 hours, that is, it stopped at about half past seven in the morning.

This data is a little different from the time it appeared at the highway toll booth in the morning, but it was a normal speed, because there was snow, so it was different.

On the vehicle where the accident occurred, only the fingerprints of two people have been found so far, Atsushi Triangle and Yasumi Osaka.

There was an unfinished can of drink in the car, which was preliminarily determined to contain fast-acting sleeping pills.

The time of death of Yasumi Osaka is preliminarily presumed to be around 12:30 p.m., and the cause of death was charcoal burning in a closed car, and finally suffocated due to lack of oxygen.

Although it is certain that the car came in the morning and then turned off the air conditioner in the car, charcoal can also be used for heating, as long as the windows are open, it is fine.

Therefore, it is uncertain when the windows of the car began to be closed and charcoal burned.

In addition, the volume of charcoal in the charcoal furnace is very small, so it is not possible to determine how long the charcoal burned according to the amount of charcoal burned, and it can only be estimated that it is an hour.

The mountain village police officer smacked his tongue and said, "That is to say, she committed suicide at half past eleven in the morning and killed for an hour." ”

Maori said, "Stupid, that's why she drank sleeping pills." ”

The forensic officer said: "I don't know this yet, but because of carbon monoxide poisoning, she was not in pain when she died." ”

The mountain village police officer held his chin and said: "Well, carbon monoxide is colorless and odorless, it is the number one killer of fires, and it is also a must be paid attention to in winter for home heating, even eating hot pot." ”

Yamazaki was amused in his heart, and he was still thinking about hot pot.

Ignoring Officer Yamamura, Mori calls Officer Yumi to report on the progress of the investigation, and Officer Yumi tells Mori that she is rushing to Tsuruto's apartment, and Officer Sato is taking Officer Takagi to Atsushi Triangle's club, and that there will be further information soon. ……

Tokyo.

The employees of the company where Atsushi Triangle works have just finished working overtime, and Officers Sato and Takagi are just in the right place.

It is understood that Triangle Du arrived at the club at 9 o'clock this morning, did not arrive late, and then spent the whole day at the club, saying that he left early in the afternoon, but in fact he went home to sort out the documents and materials for tomorrow.

In other words, at the time of Yasumi Osaka's death, to be more precise, two and a half hours before Yasumi Osaka's death, Atsushi Triangle was already in Tokyo.

Officer Sato used his mobile phone and hands-free to call Officer Yumi, explained the matter, and then asked, "Yumi, this is the case on my side, there is no clue, how is it on your side?"

Officer Yumi said with some distress: "Something's wrong."

Officer Takagi asked, "What do you say?"

Officer Yumi said, "It has been confirmed that Miss Yasumi went out with the Kazuda Crown at around six o'clock this morning, but she was the only one in the car. ”

Officer Sato said, "What's wrong with this? Mr. Triangle, he could have waited for Miss Yasumi to come over at the scene on Gunma's side." ”

"That's right, as long as it's agreed in advance. "Then he can use the sleeping pills in the drink to put Miss Yasumi down, and set up a mechanism to control the charcoal stove so that it burns again until 11 a.m." ”

"Let's not talk about it for now. Officer Yumi asked, "Have you two thought about it, how did he get back to the club?"

Officer Takagi said, "I think it's a car, or a highway bus." ”

Officer Yumi sneered: "Ha, don't even think about it, no matter which way he goes, when he arrives in Tokyo, it will be during the morning rush hour at work, and it will be absolutely impossible for him to return to the club in time." ”

"You're a traffic cop, and I trust your judgment, but can you guarantee that it's 100 percent?" Officer Sato asked, "Can you guarantee that he won't be able to make it back?"

"This ......" Officer Yumi was speechless.

"That's it," Officer Sato said, "don't waste any time, we'll see you at the road center." ”

"Well, I can only check the monitoring slowly. Officer Yumi said, then called Mori to inform him of the investigation. ……

Gunma Prefecture.

Maori received a notice here, and Triangle also received a call from a colleague who learned that the police were investigating him.

Triangle asked angrily, "Mr. Maori, Officer Yamamura, what do you mean, why did the police come to my club to check on me?"

Maori hurriedly said: "Rest the anger and anger, this is just a routine investigation, a routine investigation." ”

"You don't believe what I say, you doubt me. ”

"That's right, we're suspecting you," Officer Yamamura couldn't help but say, "The person who discovers the incident is often the murderer of the incident." ”

Triangle shouted: "Nonsense, I can't commit a crime at all." ”

Yamazaki's heart moved, "Why?"

"Didn't you say it yourself?" the car was parked here at half past seven in the morning. ”

Officer Yamamura asked, "So what?"

"Driving back to Tokyo from here coincides with rush hour, so I won't be able to get back to the club in time," says Atsushi Delta. ”

Hearing this, Yamazaki finally confirmed that Triangle Atsushi was the murderer.

This rush hour is not only the rush hour for people from Tokyo to the surrounding prefectures, but also the rush hour for people from the surrounding prefectures to Tokyo to go to work in the morning, which is a traffic flow of millions of cars.

Officer Yumi was able to know the situation and the time required to get from the scene in Gunma Prefecture to the Triangle Atsushi Kaisha because she was a traffic police officer by profession and she had a lot of experience in this area.

As for Atsushi Triangle, he lives in Tokyo, and the club is also in Tokyo, so he usually doesn't encounter rush hours outside Tokyo at all, that is, he has no experience.

As for the distance and time calculated based on a previous trip to Gunma Prefecture and then returning to Tokyo in the morning, it is impossible.

Because there was a large-scale snow damage this year, and if there was snow damage in Gunma Prefecture in previous years, they would not have come to travel.

And if you come to travel first, and then you are trapped by snow, it is absolutely impossible to return to the morning rush hour, because when it is not urgent, the roads are cleaned at dawn, and during the morning rush hour, the general roads are not cleared.

Therefore, Triangle Atsu's words only show that he has recently experimented, so he learned that he could not return to his club in time from this scene in Gunma Prefecture as a proof of his alibi.

However, he did this experiment, and the inability to return to the club in time was used as evidence, which also showed that he was the murderer.

And if you find out what means he used and return to the club in time, you will find evidence that he killed people.

The question is, how the hell did he get back?......

Since there was no way to answer the question and there was no evidence, the mountain village police officer could only let him go and ask him to go to the police station tomorrow to make a detailed record.

It could detain him, but it didn't make any sense, as long as someone followed and monitored. ……

And the triangle is alone, and the scene is all his own people, and it suddenly becomes lively.

If you don't say it, I won't say it, in a snowy day, eat some hot pot to warm up, that's really not too comfortable. ……
