Chapter 12: An Ordinary High School Student

"The deceased Henry Zhang, male, 18 years old."

"The identity is a third-year student of Qingcheng High School."

"The total attributes of the three items in the preliminary test are as high as 10, tsk tsk, you are only inferior to Gu Dui, what a pity you are a good seedling!"

Gu Sinan snorted coldly: "Old Xu, get to the point."

Xu Zhiyong was not angry, and continued: "According to the preliminary investigation, the body spots on the deceased have spread, and it is speculated that the time of death should be after school last night, that is, between 19:00 and early morning. Waiting for forensic test results."

Gu Sinan nodded.

Xu Zhiyong squatted down, his expression gradually became calm, and his voice was steady, as steady as an old dog.

"The cause of death should be the knife on the neck. The knife killed him cleanly. There were no traces of fighting at the scene. It seems that the murderer should be a veteran, and it is very likely that he was a...professional. Otherwise, with the attributes of the deceased, and On the premise of insisting on exercising, it is impossible to be killed instantly without any reaction."

"There is no other discovery at the scene, there is no trace of moving the body, and the shape of the blood spray is not interrupted. This should be the first scene."

"The scene is a secret room?" Gu Sinan looked around and asked slowly.

Xu Zhiyong sighed softly: "It can be said that it is, or it can be said that it is not. The deceased lived alone all year round, and his parents were not around. The door lock is only a three-level security algorithm. Even if it is us, with ordinary equipment, it only takes 12 minutes. The password can be deciphered, if the murderer came prepared, this door lock is useless to the murderer."

"Okay!" Gu Sinan didn't say a word of nonsense, and directed the scene directly: "Everyone, carefully search all the corners where the murderer may leave traces."

"Yes! Team Gu!"

"Old Xu, who reported the case?"

"Here, over there, it is said that he is a classmate of the deceased."

Xu Zhiyong pointed to the corner of the house.

Gu Sinan looked in the direction Xu Zhiyong pointed, and there was an "average" high school student buried behind the crowd.

His unremarkable appearance makes it easy to accidentally ignore him.

The high school student's expression was a bit cramped. Seeing Gu Sinan, he shrank into the crowd like a "frightened bird".

Gu Sinan, who has a keen intuition, deciphered the above information from a short meeting.

...

...

"Name?"

"Irin."

"gender?"

"Sister, I don't seem to have grown to the point where male and female are indistinguishable..."

"Stop talking nonsense, what can I ask you? Gender?" Gu Sinan sternly shouted.

"male……"

"age."

"18."

"You were the first to discover the body? How did you have the code for the dead man's door lock? What is your relationship with the dead man?" Gu Sinan asked three questions in succession with his mouth like a machine gun.

"This..." Yi Lin was taken aback for a moment, then pointed at the helpless Xu Zhiyong beside him, and said in a low voice, "This uncle has already asked this question once."

The corners of Xu Zhiyong's eyes twitched, he couldn't stand it anymore, and stopped Gu Sinan who was about to explode: "Captain Gu, I checked this student just now, he was a classmate of the deceased, and he had a good relationship with the deceased before his death, and he was considered honest in the eyes of his classmates. That kind, parents have been working abroad for a long time, so there is no problem with their status.”

After a pause, Xu Zhiyong handed the tablet to Gu Sinan, pointed to the content on it and continued: "As for why he came to the deceased's house, it was because the deceased hadn't gone to school all day, and the head teacher asked him to come to the deceased... I confirmed with the teacher of the deceased that this is indeed the case. Well, there is no doubt."

When Gu Sinan heard this, he let out a little surprise, then stared straight at Yi Lin, and remained silent.

She is very clear about the "doubts" that Xu Zhiyong said,

What is meant.

In many classic murder cases, in order to eliminate his own suspicion, the murderer will often do the opposite, take the initiative to find the body, and involve himself in the case.

If this kind of tactic was placed at the beginning of the last century, it might still work.

But up to now, this has been a rotten routine mastered by every criminal investigator.

Hmph, this is the first lesson of anti-routine subjects for criminal investigators.

one second.

three seconds.

Erin looked away.

"Don't you dare to look me in the eyes? There are ghosts in your heart?" Gu Sinan's eyes lit up.

"No." Yi Lin shook her head.

"Then why don't you dare look into my eyes?" Gu Sinan took a step forward, approaching Yi Lin.

Yi Lin was silent for a moment, then turned her head suddenly, and asked the young police officer who was closest: "Are you afraid of her?"

"Afraid, ah no no no, not afraid, not afraid." The young police officer subconsciously said what was in his heart, but immediately changed his words with a sarcastic smile.

Gu Sinan: "..."

Xu Zhiyong: "..."

"Here, it's nothing. I'll check elsewhere first." Feeling that the atmosphere was not quite right, the young police officer who knew he had said something wrong wanted to slap several times, and slipped out with a random excuse. .

"Heh." Yi Lin sighed suddenly, then smiled helplessly: "All right, I'll tell the truth."

Gu Sinan was slightly taken aback.

Even Xu Zhiyong, an experienced criminal policeman, couldn't help being stunned when he heard Yi Lin's tone change.

Could it be that he had misjudged himself?

"I'm actually not a good friend of Henry Zhang at all." Yi Lin looked at Henry Zhang's body not far away: "He is relying on the fact that his total attributes are much higher than mine, and he keeps asking me to run errands and do homework. In the eyes of other students, I may be his good friend, but in fact, Henry Zhang didn't regard me as a friend at all, I actually know it very well. How can ordinary people like us deserve to be friends with geniuses?"

The voice was a little bit downcast, desolate, and also a bit helpless to reality.

"Since you have a bad relationship with the deceased, why did you come to him?"

Gu Sinan quickly realized that there was a doubtful point in the information Xu Zhiyong provided before.

Yi Lin remained silent, just took out a completed history homework from the schoolbag behind her, and handed it to Gu Sinan.

"First of all, this is the head teacher's order. Secondly... I have to return the homework to him." After a pause, Yi Lin smiled wryly: "If I knew in advance that this kind of thing would happen, even if I was killed, I wouldn't be here. Come in at a time like this."

Upon hearing this, Gu Sinan casually flipped through a few pages of neatly written history homework, fell silent, and fell into deep thought.

At this time, another police officer came with a palm-sized tablet computer in his hand.

"Gu Dui, the images stored by the AI ​​housekeeper have been downloaded."

"good!"

Gu Sinan didn't talk nonsense, and directly checked the video data recorded by the AI ​​housekeeper.

Home from Henry Zhang...

exercise……

Then a girl came in halfway...

Then something indescribable happened...

"Tut tsk tsk." Xu Zhiyong instantly showed a knowing expression of an old driver.

Gu Sinan gave Xu Zhiyong a hard look, then poked his finger on the screen hard, fast forward, fast forward, fast forward, finally skipped the unsuitable scene, and continued to look down.

Henry Zhang enters the gym...

Until 22:18.

The image is abruptly interrupted.

"Gu Dui, I just went to check here. Since 22:18, the circuit in the community has malfunctioned, but now it seems that the murderer cut off the power, so it's... gone."

"No backup power?"

"This AI butler is just a home version, and the home version of the AI ​​butler generally doesn't have a backup power supply." The young policeman explained helplessly.

...

When the image reappeared, the time was 23:49.

Henry Zhang has become a cold corpse.

In addition to Henry Zhang's body, there are no traces of the murderer in the room.

Gu Sinan remained expressionless and continued to fast-forward until he saw the scene where Yi Lin entered the door and found the dead body.

"What about surveillance in the community?"

"I have asked people to get it as soon as possible, but I may have to go back to the game to study it slowly."

"What about the forensic doctor?"

Xu Zhiyong looked at the time: "Should arrive in 20 minutes."

"Give them another ten minutes, if they don't come within ten minutes, they won't be used in the future."

"..."
