"The deceased, Xiao Yang, was male and 18 years old."
"I am a third-year student at Qingcheng High School."
"The total three attributes of the initial entrance test are as high as 10. Tsk tsk, they are only slightly inferior to you, Captain Gu. What a pity that you lost a good seedling!"
Gu Sinan snorted coldly: "Old Xu, tell me the important point."
Xu Zhiyong was not angry and continued: "According to the preliminary investigation, the body spots on the body of 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 morning. The more specific time of death may be
Waiting for the forensic test results.”
Gu Sinan nodded.
Xu Zhiyong squatted down, his expression gradually became calmer, and his voice was as steady as an old dog.
"The cause of death should be the stabbing on the neck, killing him with one stabbing, clean and neat. There are no traces of struggle at the scene. It seems that the murderer should be a veteran, and most likely... a professional. Otherwise, based on the attributes of the deceased, and
As long as you keep exercising, you won't be killed instantly without any reaction."
"There were no other findings at the scene, there were no signs of the body being moved, and there was no interruption in the shape of the blood spray. This should be the first scene."
"Is this 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 are not around. The door lock is only a three-level security algorithm. Even for our people, using ordinary equipment, it only takes 12 minutes.
The code can be cracked. If the murderer comes prepared, the door lock will be useless to the murderer."
"Okay!" Gu Sinan directed the scene without any nonsense: "Everyone, carefully search all corners where the murderer may have left traces."
"Yes! Team Gu!"
"Old Xu, who reported the case?"
"Well, over there, it is said that he is the deceased's classmate."
Xu Zhiyong pointed to the corner of the room.
Gu Sinan looked in the direction Xu Zhiyong pointed, and saw an "ordinary" high school student buried behind the crowd.
His ordinary appearance makes it easy for people to ignore him accidentally.
The high school student's expression was a bit awkward, and when he saw Gu Sinan looking at him, he looked like a "frightened bird" and shrank back into the crowd.
Gu Sinan, who has keen intuition, deciphered the above information from a short interview.
…
…
"Name?"
"Yirin."
"gender?"
"?"
"Gender?" Seeing that Yi Lin lowered her head and didn't answer, Gu Sinan raised her voice and asked again.
"male……"
"age."
"18."
"You were the first to discover the body? How did you get the password for the deceased's door lock? 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 stunned for a moment, then pointed to Xu Zhiyong, who looked helpless next to him, and whispered: "This uncle has already asked these questions once."
Xu Zhiyong's eyes twitched and he couldn't stand it anymore. He stopped Gu Sinan who was about to have a fit and said, "Captain Gu, I just checked this student. He is a classmate of the deceased. He had a good relationship with the deceased before his death. He is considered honest and honest in the eyes of his classmates."
That kind, my parents have been working abroad for a long time, so there is no problem with my identity."
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 did not go to school all day, and the head teacher asked him to come to the deceased... I just said
I have confirmed with the teacher of the deceased that this is indeed the case. Well, there is no doubt about it."
Hearing this, Gu Sinan let out a light sigh, then stared straight at Yi Lin, silent.
She knew very well what Xu Zhiyong meant by "doubts".
In many classic murder cases, in order to eliminate his own suspicion, the murderer often goes in the opposite direction, actively discovers the body, and involves himself in the case.
This kind of trick might still have worked if it had been used at the beginning of the last century.
But now, this is a routine that every criminal investigator has mastered.
Hum hum, this is the first lesson in anti-routine training for criminal investigators.
One second.
Three seconds.
Yi Lin looked away.
"Don't you dare look into my eyes? Is there something wrong in your heart?" Gu Sinan's eyes lit up.
"No." Yi Lin shook her 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 her head and asked the nearest young police officer: "Are you afraid of her?"
"Alas, ah, no, no, not afraid, not afraid." The young police officer first said subconsciously, but immediately smiled and changed his mouth.
Gu Sinan: "..."
Xu Zhiyong: "..."
"Here, there's nothing wrong. I'll check somewhere else first." Sensing that something was not right in the atmosphere, the young police officer who knew he had said the wrong thing wanted to slap him in the face a few times, and casually found an excuse and slipped out.
.
"Heh." Yi Lin suddenly sighed, then smiled helplessly: "Okay, I'll tell the truth."
Gu Sinan was slightly startled.
Even Xu Zhiyong, as an experienced veteran detective, couldn't help but be stunned when he heard Yi Lin's change of tone.
I secretly wondered if I had made a mistake?
"Actually, I'm not a good friend of Henry Zhang at all." Yi Lin looked at Henry Zhang's body not far away: "Isn't he just relying on his overall attributes to be much higher than mine, so he keeps asking me to run errands and do my homework. In the eyes of other classmates,
I may be his good friend, but in fact, Henry Zhang does not regard me as a friend at all, and I actually know it very well. How can people with ordinary attributes like us deserve to be friends with geniuses? "
The voice sounded a bit downcast, desolate, and helpless to reality.
"Since you had a bad relationship with the deceased, why did you come here to find him?"
Gu Sinan quickly thought of a doubtful point in the information Xu Zhiyong provided before.
Yi Lin remained silent, but took out a written history assignment from the schoolbag behind her and handed it to Gu Sinan.
"First of all, this is the class teacher's order. Secondly... I have to return the homework to him." After a pause, Yi Lin smiled bitterly: "If I knew in advance that... this kind of thing would happen, I wouldn't be here even if I was beaten to death.
Come running in at this time."
When Gu Sinan heard this, he flipped through a few pages of neatly written history homework and fell silent, lost in thought.
At this time, another police officer came over with a palm-sized tablet computer in his hand.
"Team Gu, the images stored by the AI Butler have been downloaded."
"good!"
Gu Sinan didn't waste any time and directly checked the image data recorded by the AI butler.
Going home from Henry Zhang...
exercise……
Then a girl came in halfway...
Then something indescribable happened...
"Tsk, tsk, tsk." Xu Zhiyong instantly showed a knowing expression like that of an experienced driver.
Gu Sinan glared at Xu Zhiyong fiercely, then pressed her finger hard on the screen, fast forward, fast forward, fast forward, finally skipping the scenes that were not suitable for children, and continued reading.
Henry Zhang enters the gym...
Until 22:18.
The image is suddenly interrupted.
"Captain Gu, I just went to check here. Starting from 22:18, the circuit in the community broke down. But now it seems that the murderer cut off the power supply, so it was... gone."
"No backup power?"
"This AI Butler is only a home version. The home version of AI Butler generally does not have a backup power supply." The young police officer explained helplessly.
…
When the image reappeared, the time was 23:49.
Henry Zhang has become a cold corpse.
Apart from Henry Zhang's body, there were no traces of the murderer anywhere in the room.
Gu Sinan continued to fast forward with no expression on his face until he saw the scene where Yi Lin came in and found the body.
"Where is the surveillance in the community?"
"I've asked someone to pick it up as soon as possible, but I may have to go back to the bureau to study it slowly."
"Where's the forensic doctor?"
Xu Zhiyong looked at the time: "Should arrive in 20 minutes."
"ten minutes."
"..."
