"The deceased Xiao Yang, male gender, 18 years old."

"I am a third-year student in Qingcheng High School."

"Enrollment In the first test, the total attribute of the three items is as high as 10. tsk tsk is only inferior to Squad Leader Gu. What a pity it is a good seed!"

Gu Sinan coldly snorted: "Old Xu, let’s talk about the main point. "

Xu Zhiyong was not angry, and continued: "According to the preliminary investigation, the corpses on the deceased have spread. It is speculated that the time of death should be after school last night, that is, between 19:00 and early in the morning. , More specific time of death may have to wait for forensic test results."

Gu Sinan nodded.

Xu Zhiyong squatted down, his expression gradually became calm, and his voice calm, as steady as Old Dog.

"The cause of death should be this blade on the neck. It was killed with a single knife. There was no trace of fighting on the scene. It seems that the murderer should be a veteran, and it is likely to be a...professional. Otherwise. Based on the attributes of the deceased and the premise of insisting on exercising, impossible was killed in a flash without any response."

"There was no other discovery at the scene, and the corpse had no traces of movement, and the blood was sprayed in the same shape. There is no interruption, it should be the first scene here."

"The scene is a secret room?" Gu Sinan asked slowly, looking around.

Xu Zhiyong sighed softly: "You can say yes, you can also say no. The deceased lives alone all the year round and his parents are not around. The door lock is only a Level 3 security algorithm. Even if it is our people, use Normal equipment, it only takes 12 minutes to crack the password. If the murderer is prepared, this door lock is completely useless to the murderer."

"Good!" Gu Sinan is no half. Nonsense, direct the scene: "Everyone, carefully search all corners where the murderer may leave traces."

"Yes! Squad Leader Gu!"

"Old Xu, yes Who reported the case?"

"Here, over there, it is said to be the classmate of the deceased."

Xu Zhiyong pointed to the corner of the house.

Gu Sinan looked in the direction that Xu Zhiyong pointed out. In between, a high school student who looked "normal" was buried behind the crowd.

His unremarkable appearance makes it easy to accidentally ignore him.

The high school student's expression has several points of cramped. Seeing Gu Sinan, he looked like a "frightened bird", with his body retracted into the crowd.

Gu Sinan, who is intuitive and keen, interprets the above information from a short encounter.

……

……

"Name?"

"Yi Lin."

"Gender ?"

"Sister, I don’t seem to have grown to be male and female..."

"Stop talking nonsense, what do you say. Gender?" Gu Sinan board Face coldly shouted.

"Male..."

"Age."

"18."

"Are you the first to find a dead body? Why do you have the code for the door lock of the deceased? What is your relationship with the deceased?" Gu Sinan's mouth was like a machine gun, and he asked three questions in a row.

"This..." Yi Lin was taken aback for a moment, then pointed to Xu Zhiyong with a helpless expression next to him, and whispered: "This Uncle has already asked this one time earlier."

Xu Zhiyong's eyes twitched, and he couldn't stand it. He stopped Gu Sinan who was about to attack: "Squad Leader Gu, I checked this student just now. It was a classmate of the deceased. He had a good relationship with the deceased. In my eyes, it is the kind of honest and timid. My parents have been working abroad for a long time and there is no problem with their identity."

After a while, Xu Zhiyong handed the tablet to Gu Sinan, pointing to the content above and continuing. "As for why he came to the deceased’s house, it’s because the deceased didn’t go to school all day, and the head teacher asked him to court the death... I just confirmed with the deceased’s teacher that there is indeed such a thing. There is no doubt."

Gu Sinan hearing this, lightly exclaimed, then stared straight at Yi Lin, silent.

She knows very well what Xu Zhiyong's "suspicious point" refers to.

In many classic murder cases, in order to eliminate their own suspicion, the murderer will often go the other way, actively discovering the dead body and getting himself involved in the case.

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

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

Hmph, this is the first lesson of the criminal investigator’s anti-routine subject.

One second.

Three seconds.

Yi Lin looked away.

"Dare to look in my eyes? There is a ghost in my heart?" Gu Sinan's eyes lit up.

"No." Yi Lin shook his head.

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

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

"Afraid, ah no no no , I'm not afraid, I'm not afraid." The young police officer first subconsciously said what was in his heart, but immediately smirked and changed his words.

Gu Sinan: "..."

Xu Zhiyong: "..."

"This, it's okay. I'll check it elsewhere first." When the atmosphere was not quite right, the young police officer who knew he had said the wrong thing wanted fiercely to slap a few times, found a reason and slipped out.

"Heh." Yi Lin suddenly sighed, then laughed helplessly: "Okay, I'll tell the truth."

Gu Sinan was slightly taken aback.

Even Xu Zhiyong, an experienced veteran detective, couldn't help being stunned when Yi Lin's tone changed.

Is it possible that the secret path has gone wrong by yourself?

"I'm actually not a good friend of Xiao Yang at all." Yi Lin looked at Xiao Yang's body not far away: "Isn't he just relying on his total attribute to be much taller than me, so he keeps letting me run errands and do homework In the eyes of other classmates, I may be his good friend, but in fact, Xiao Yang didn’t treat me as a friend at all. I actually know very well. How can ordinary people like us be worthy of being friends with geniuses?"

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

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

Gu Sinan soon thought of the information Xu Zhiyong provided before that there was a suspicious point .

Yi Lin remained silent, but took out a written history homework from his schoolbag behind him and handed it to Gu Sinan.

"First of all, this is the order of the class teacher. Secondly...I have to return the homework to him." Paused, Yi Lin smiled wryly: "If you know in advance that... this kind of thing will happen, even if you kill him. I won't run in at such a time."

Gu Sinan hearing this, turning over a few pages of neatly written historical homework, was silent and lost in thought.

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

"Squad Leader Gu, the images stored by AI steward have been downloaded."

"Okay!"

Gu Sinan is no nonsense, just check AI steward directly The recorded image data.

Going home from Xiao Yang...

Exercise...

Then a girl came in halfway...

Then something happened The indescribable thing...

"tsk tsk tsk." Xu Zhiyong instantly showed an old driver's clear expression.

Gu Sinan fiercely glared at Xu Zhiyong, then poked his finger on the screen, fast forward and fast forward, finally skipped the unfavorable shots for children, and continued to look down.

Xiao Yang enters the gym...

Until 22:18.

The image is suddenly interrupted.

"Squad Leader Gu, I just checked here. Starting from 22:18, the circuit in the community failed, but now it seems that the murderer cut off the power, so... "No backup power supply?"

"This AI steward is only a home version, and the home version of AI steward generally does not have a backup power supply." The young police officer explained helplessly road.

……

When the image reappears, the time is already 23:49.

Xiao Yang has become a cold corpse.

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

Gu Sinan continued to fast forward with no expression on his face, and kept seeing Yi Lin entering the door and finding the corpse.

"What about monitoring in the community?"

"It has been taken as soon as possible, but may have to be returned to the bureau to study it slowly."

"What about the forensic doctor?"

Xu Zhiyong looked at the time: "It should be there in 20 minutes."

"Give them another ten minutes. If they don’t come within ten minutes, they won’t need to come in the future. Coming."
