Coroner Coroner

Lin Xinyi threw out several questions in a row, with a rather intimidating manner.

But Qianjian Jiangdai laughed easily instead:

It turned out that this was Lin Xinyi's strategy.

The forensic method did not work, and the police's stupid method was used.

It is nothing more than continuously asking the suspect to answer questions through interrogation, describing in detail his experience during the time period of the crime, and then trying to find loopholes in the details.

If the suspect is the real murderer, then the experience described in his testimony can only be fabricated.

Since it is fabricated, theoretically the police may find loopholes in his testimony.

If there is a contradiction between the testimony and the facts and it is found to be a forged testimony, then this can become a kind of powerful criminal evidence in court.

"It's a good idea."

"But...is it really that easy to find loopholes in my testimony?"

If this kind of stupid method can be eaten all over the world with one trick, then why do you need a detective?

Qianjian Jiangdai smiled helplessly in his heart.

Then he organized his language again and replied carefully:

"When did I come to the Pavilion of Twilight, Mr. Lin, it's not like you don't know."

"It was around 6 p.m., and you brought me here when the car broke down halfway, didn't you?"

There is only one way to the Twilight Pavilion.

The first to arrive was Ogami Tokuzen, followed by the maid, Ikumi Gunida, and Haruka Motegi.

On the way Motegi Haruki came, he didn't run into Senma Kodai whose car broke down.

The Qianjian generation could only drive to this mountain road after Motegi Haruki and before Lin Xinyi arrived, that is, around 6 pm.

This is an established fact, and she cannot change it.

Therefore, Qianjian Xiadai can only follow this situation:

"I didn't drive to this mountainous area until around 6 p.m.."

"As a result, the car broke down halfway before reaching the Twilight Pavilion."

"As for before 4 p.m...."

"I should still be at home."

Qianjian Jiangdai explained unhurriedly:

"I have a villa in the countryside of Tottori Prefecture, which is about four and ten minutes away by car."

"Because the drive was so short, I didn't go to a store, a petrol station or anyone else to see me."

"And I usually only live alone, so no one can prove it during the time I was at home."

No one can prove she was at home at the time.

That is, no one can prove that she was not at home at the time.

The experience fabricated by Qianjian Jiangdai seems vague and suspicious, but in fact it caused the police the most headache.

There was no one else in the whole story except her, and Lin Xinyi couldn't find out even if he wanted to.

And the roads in this world are not monitored.

She walked the whole journey on a sparsely populated country road.

No one knew exactly when she drove away from home and when she rushed to the mountainous area where the Twilight Pavilion was located.

Qianjian Jiangdai felt that he was very stable.

That's what she was thinking.

But suddenly Lin Xinyi asked:

"Detective Qianjian, when you came here early this afternoon to poison the teacup, did you bring your mobile phone with you?"

"Huh?" Qianjian Jiangdai was slightly taken aback.

"Is the phone turned on?"

"..." Qianjian Xiangdai had a bad premonition in his heart.

"It seems to be powered on."

Lin Xinyi smiled:

"The Twilight Pavilion is indeed outside the coverage of mobile phone signals."

"But the only mountain road that comes here from the outside world, there is still a section of the road that is covered by signals."

"If your mobile phone is on and you drive here, the mobile phone number will automatically shake hands with the local base station to connect."

"There will be a registration record of your mobile phone number on the local base station."

"This record includes the time when you appeared in this mountain area."

"Understood, Detective Qianjian?"

Mobile phone numbers can be used to check historical action trajectories, which is something everyone who has experienced epidemic prevention and control knows.

Qianjian Jiangdai said that he was still at home at 4 pm.

But as long as you check the mobile phone number registration records of the base station, you will know which base station she was in at that time.

"I recorded everything I said just now."

Lin Xinyi took out the recording pen hidden in his pocket, and said with a smile:

"All the detectives here can also be witnesses."

"Qianjian mother-in-law, if the base station registration record shows that your location at that time does not match your testimony, then you have nothing to explain."

"You..." Qianjian Jiangdai's face darkened:

"Stop joking, Mr. Lin."

"The communication system can only grasp the LAC location area code and base station number of the mobile phone in real time, and will not record historical information."

"As long as there is no call, no text message, and no bill generated, the operator will not record the user's historical action trajectory."

She is also a famous detective living in the age of technology.

Although I haven't studied in Hawaii, it can be said that I have read a lot.

Use this common sense of communication to bluff people, who do you look down on?

"Oh, so you understand."

"No wonder you dare to make it up."

Faced with the calmness of Qian Jian, Lin Xin showed no sign of timidity.

So what if she understands modern science?

What he knows is futuristic science fiction.

"Sorry, Thousand Detectives."

"You are right, the base station can only be used for real-time positioning, and will not save historical registration records."

"but…"

However, operators can collect and store these real-time information through third-party systems.

Because in the future era of big data, these user data are valuable treasures that can be tapped.

Although I don't know if there is such a real-time data collection system.

嗏

"I have." Lin Xin spread his hands:

"After receiving the invitation from the Twilight Pavilion, it was two days ago."

"I asked a 'friend' to cooperate with the communication operator to secretly monitor the signal base stations closest to the Twilight Pavilion."

Friend naturally refers to artificial intelligence Noah's Ark.

As for the operator... This communication company was run by Sonoko Suzuki's family.

With such a strong network of people and such sci-fi technology, isn't it easy to collect real-time registration information of several base stations?

"That is to say..."

"Who has been here in the past two days, and when did they come?"

"As long as he has a mobile phone with him, I have records in my hand."

Chapter 564 Angels Can Lie Too

Facing Lin Xinyi's killer move, Qianjian Jiangdai quietly fell silent.

She didn't say anything more to argue.

The previous tit-for-tat momentum was also swept away.

This is undoubtedly an admission of defeat.

Witnessing this scene, all the famous detectives present had subtle expressions.

They were all amazed at the novelty of Lin Xinyi's moves.

At the same time, I was shocked to find that:

Lin Xinyi once said that "detectives will lose their jobs sooner or later" seems to be being realized step by step.

After all, like today...

From the beginning to the end, Lin Xinyi used the three tricks of checking the property rights of the house, finger drug testing and base station monitoring to crack the traps set by the two famous detectives.

Except for the "finger drug test" which cannot be imitated by normal people, the other two tricks are all tricks that elementary school students can learn to use.
