Dangerous Personality

This was the first time Shen Xinghe appeared in front of them.

This face was superimposed with the face on the ID photo, and it was also superimposed with the figure of the person standing at the window of Guangyuan cafeteria a few days ago.

On the day of the news broadcast, the auntie in the cafeteria was sobbing at the small TV in the cafeteria while cooking meals for the students enthusiastically.

The hand holding the dinner plate by the window moved, and along the way, there was a face wearing glasses.

He glanced at the TV next to him, and said, "Thank you."

"Do you know why we are looking for you?"

"not very clear."

"You don't have classes at Guangyuan, and you haven't asked the teacher for leave. What are you doing at the car dealership?"

"Interested in auto repair."

"You are now in the third year of high school, and your grades are also the first in the whole year. Are you interested in auto repair?!"

"..."

In the interrogation room, the teenager was wearing an off-white woolen sweater. He was calm and gloomy. Through the glasses, the criminal police opposite him couldn't see the look in his eyes.

Since he was involved in car repairs these two days, Shen Xinghe had a band-aid on the second knuckle of his index finger.

He rubbed the pad of the other finger on the bandage a few times, and then said lightly: "The class in school is too boring."

Interpol: "You don't take the exam?!"

Shen Xinghe: "Guarding should be fine."

There was silence.

Shen Xinghe said that this is not showing off, but just telling a plain fact: "That's why I said it's too boring, I want to find something to do."

The criminal policeman raised his voice a little: "Find something to do, you can't do what you want to do, why not become a car mechanic?"

Sitting opposite Shen Xinghe, he really didn't look like a suspect.

He has excellent grades, looks good, and is young, the age when he should sit in the classroom and study—although the murderer in the previous cat murder case was younger than him, but because of his young age, he couldn't control his emotions. Emotions, the dislike of his younger brother is very obvious.

But this cannot be seen in Shen Xinghe.

He said without emotion: "I said, I'm interested."

"Why didn't you notify the teacher?"

"Because the teacher won't let me out."

He was very firm in the matter of auto repair, and the interrogator changed the question: "Your mobile phone was confiscated by the teacher. What page did you browse on the mobile phone at that time?"

Shen Xinghe replied fluently: "News, pushed by mobile phone."

"Follow the news so much?"

"An accident happened in a nearby school, and the whole city is paying attention."

"..."

The large glass window in the observation room was very close to Shen Xinghe, and the young man seemed to be sitting in front of them. Chi Qing and Xie Lin could clearly see Shen Xinghe's expression through the glass.

Xie Lin said: "He is very calm, even if someone is caught, this matter may still be a bit difficult."

Not long after, Ji Mingrui withdrew from the next room: "This kid is too calm, that mouth can't be pried away!"

It was his overly calm reaction that made everyone present realize that even if someone was caught, they still hadn't got enough evidence to identify him.I originally thought that a student who is still in high school, where can it be so difficult?

I didn't expect it to be really difficult.

Shen Xinghe seemed to be sure that they didn't have conclusive evidence yet.

Xie Lin squeezed Chi Qing's hand through the glove, held it in his hand and played with it for a long time, when he suddenly thought of something.

Chi Qing also thought of one thing: "I'll try to touch him in the past."

Although he has no interest in what other people are thinking, and has no intention of spying on anyone, he occasionally thinks of Yu Lan's big gentle eyes.

It seems that something has changed unconsciously.

At some point, he no longer loathes, nor fears.

Xie Lin didn't let go of his knuckles: "Do you know what the power of science is? Modern science can also read whether he is lying."

At this point, Xie Lin turned his head and said to Ji Mingrui, "Give him a lie detector test."

In general, they rarely use a polygraph unless it is absolutely necessary.

Most of the people who were interrogated were still able to reveal clues from their emotions and conversations. When the lie detection step was used, there was really nothing they could do about the other party.

Xie Lin: "A lie detector cannot be used as evidence, but it can give people a sense of pressure. When a person knows that he is lying will be detected by machine sensors, can he speak so nonchalantly? His pulse, heartbeat , heart rate, blood pressure, respiration, which one will 'betray' him?"

The cold machine was quickly put on the table, and Shen Xinghe followed instructions to put his right hand finger on the sensor, and then his wrist was tied with a red bandage.There are several wires connected to the polygraph, one of which leads to the computer. On the computer screen on the table, something similar to an electrocardiogram appears, which is responsible for collecting data in different bands.

If the data is abnormal, the band will change accordingly. When the line changes from green to red, the machine will make a beep.

The conversation continues.

Going back to the first sentence, the criminal policeman in front of Shen Xinghe asked the question again: "You really don't know why we are looking for you?"

Shen Xinghe only gave the machine a look when he was putting on the device, and then looked away indifferently, then he repeated the answer just now: "Not sure."

Interpol: "South China City where you transferred?"

Shen Xinghe: "My family's job has changed."

Interpol: "Have you heard of Honghai No. [-] Middle School before?"

Shen Xinghe said: "Before the accident, I didn't pay much attention to it."

"..."

Shen Xinghe's tone of voice remained unchanged, and the frequency bands on the computer screen fluctuated up and down in small increments.

After a while, he said again: "... can I have a glass of water."

Shen Xinghe's brows and eyes were cold, he didn't actually have much affinity, but the eyes on the bridge of his nose neutralized that feeling, suppressed that indifference, and made him look more refined.He rested his fingers on the wall of the water glass and took a sip of water in a leisurely manner.

At the same time as the glass of water was handed to him just now, there was also a death file of Honghai No. [-] Middle School.

The cover of the file says four different times.

Four lines were written in black pen, each representing the time of death of a person.

At the same time as he put down the water glass, the criminal police turned to the first page according to the instructions of the people in the observation room next door.

The first page is Wang Yuan who was found in the woods.

"Do you know this person?"

"I don't know," Shen Xinghe put down the water glass, glanced at Wang Yuan's photo calmly, and said, "I don't know why you want to show me these."

The band continues to float up and down the horizontal line slightly.

Even if Wang Yuan's photos and death records were right in front of him, the machine couldn't capture any fluctuations in him.

The lie detector never went off.

Everyone couldn't help but frowned.

"If it was really him who did it," Ji Mingrui encountered such a person for the first time, "then his psychological quality is nowhere to be found. He has an impregnable fortress, and he is impeccable."

Even Xie Lin, a weirdo who looks at people with a microscope, failed to capture details useful to the case from his reactions, and had to admit a fact: "It may be useless to interrogate him, we still have to go to the Find evidence."

"His motive for killing is obvious. It is related to the death of his younger brother Xu Xingzhou. In other words, there must be something strange about Xu Xingzhou's death. The person who knows this most well is Jiang Yiyun, who was the last one the murderer wanted to kill but failed to do. gone."

Interrogations were useless, and lie detectors were of no use.

They don't have time to spend any more time here with him.

Xie Lin reminded Chi Qing: "Put on your coat, it's quite cold outside at night, let's go to Jiang Yiyun's house."

However, just when a few people were about to leave——

To everyone's surprise, the bands on the computer screen changed a bit.

"Wait—" Ji Mingrui glanced forward and saw the curve, "His heart is beating faster."

Although it was very small, far from the level that triggered the "beep", it did speed up.

Chi Qing noticed the file in front of Shen Xinghe: "The file in front of him has already turned two pages, just turn one more page..."

Xie Lin: "Just turn one more page to find the last victim's information."

They knew who the last victim was.

It was "Yu Yang" that the murderer thought.

Among these few people, the murderer was the only one who wanted to let go.

If this conversation can expose Shen Xinghe's flaw, then Yu Lan on the last page may be that flaw.

Shen Xinghe lowered his eyes, watching the criminal police opposite him turn to the last page of the file.

His eyes fell on the first line of the victim's name.

The paper was not completely turned over, half of the name was covered.

Yu...

When the last page slowly fell, the following word appeared: Lan.

Yu Lan's photo is posted on the upper right corner of the profile page.

The girl has big eyes, smooth hair, light makeup, and very light lipstick. She was a little shy when she took a picture of her ID card and looked at the camera.

Shen Xinghe's pupils dilated slightly.

Only at this moment, a completely different expression appeared on his face, and his hand on the sensor moved unconsciously.

Among the several different curves, one fell down in the shape of "—" and lasted for a second.

Ji Mingrui's upper body was almost stuck to the big glass in front of him, and he was closer to the computer screen in front of him. He shouted: "There is a reaction, his heartbeat stopped for a second!"

The criminal policeman is experienced, he caught the pause and fall of that second from the corner of his eye, and chatted with him about the deceased on the page: "She was the victim of the fire case some time ago, you follow the news so much, you should have seen it too. , the fire was very big that day, and she was waiting for someone to go to a movie that she had been looking forward to for a long time in the building, but something happened that day, an accident happened, and the door was locked. call for help..."

In the end, the criminal police stared into the boy's eyes and asked word by word: "Do you know her?"

After Shen Xinghe's heart skipped a beat, it suddenly lost its balance.

The curve on the computer screen is no longer as smooth as before—even though the boy sat there, his complexion and expression were the same as when he first came in, he looked as if he was really an intruder, this It was all just a misunderstanding, and when the interrogation was over, he would go back to school and continue his lessons.

After a while, Shen Xinghe opened his mouth to the page full of words, his voice was slightly stuttering: "I... don't know."

In this conversation, he said a lot of "don't know".

But this "don't know" is different from all the previous don't know.

Because it was the second he spoke.

The lie detector, which was so silent as if it had malfunctioned, made its first sound:

"--drop."
