Gu Sibei saw that everyone in the monitoring room was waiting for him to speak, so he didn't keep them in suspense any longer and said bluntly,"
"According to the modus operandi and the layout of the crime scene…"
"Killer, male, student of our school.”
"His height is between 173-176 cm.”
" Around 23 years old."
"He's skinny and doesn't come from a good family.”
"He likes to pursue perfection and has a serious obsessive-compulsive disorder.”
"You have a girlfriend or someone you have a deep crush on.”
"He's a little paranoid and eccentric. His academic results should be very good.”
"I usually like to wear dark colors, such as black and dark gray.”
"He didn't have any interactions with the deceased, but he had a competitive relationship. We can start from Professor Qi.”
"Also, there should be a precedent of assaults before this case. You can check from the school if there were any cases of people fainting after being attacked but not losing anything.”
Everyone fell silent.
Xiao Liu hesitated for a while, but still opened her mouth to ask the question in her heart," Why is it a man? Wasn't the victim not raped? And it might not be a young man, it could also be an employee of the school, right?”
Gu Sibei smiled at Xiao Liu." The murderer didn't defile the victim because he thought the victim was dirty, so he took off the victim's clothes.”
"Even the hair on his body has been shaved clean. This can also prove that the murderer has a morbid obsessive-compulsive disorder. Otherwise, he wouldn't even let go of his hair.”
"Usually, when the victim's clothes are stripped, everyone will naturally think that they must have been defiled. However, the murderer did not do this. His purpose was to humiliate the victim and at the same time, show his loyalty to the person he liked.”
"Of course, we can't rule out the possibility that he's trying to confuse the police.”
"As for why it's a young man…"
"Because of the symbol and the blood on the wall.”
Shayi blurted out in surprise," God Gu! Do you know what that symbol is?”
Gu Sibei smiled." I thought it looked familiar and thought it was an ancient totem. I remembered it later."”
"That's the symbol of Capricorn among the twelve constellations!”
Of course, Gu Sibei didn't remember it, but he found it in the encyclopedia on his way here.
After all, people were like this. The more familiar something was, the more it was on the tip of their tongue. The more they couldn't think of it and couldn't say it.
Also, the 200,000 Worship Points could not be wasted. They had to be used to their full potential.
Gu Sibei continued," Professor Qi had previously given a lecture on analyzing the effects of the twelve zodiac signs on people from a psychological perspective.”
"I think the murderer should have been in class at that time.”
"In addition, the blood stains on the wall are very evenly distributed. The direction and strength are consistent.”
"Generally speaking, only a young man would be able to pay attention to the details on the blood wall after spending so much energy killing the victim.”
"Unless this old man or old lady is usually a fitness expert. But obviously, there is no one in our school who meets these conditions.”
Sand One was speechless.
Shayi opened his mouth in shock after hearing these words.
He knew it! God Gu said he understood a little! It meant that he was very professional!
The other police officers were also dumbfounded.
This was comparable to the classic cases he learned in the police academy!
Gu Chen thought about it suspiciously for a moment before beckoning Xiao Liu to whisper a few words to him.
Xiao Liu nodded and called another policeman to go out with him.
Just as she reached the door, she bumped into Li Tao, who was sweating profusely and running back anxiously.
“duang！”
Xiao Liu was knocked back a few steps.
Li Tao lost his balance and almost fell with the lunch box in his hand. Fortunately, Gu Sibei quickly pulled him back.
"Thank you! Thank you!"
Li Tao quickly thanked him. When he looked up, he saw Gu Sibei staring at his bruised arm.
She quickly pulled her hand away and pulled down her sleeve." I'm sorry, I'm sorry. I was in a hurry and didn't look at the road. I didn't see you guys walk out.”
Gu Chen saw Li Tao pulling up his sleeves in a panic.
Gu Sibei's gaze was still locked on Li Tao's arm.
There was something wrong with this Li Tao. Why was he so afraid that others would see his injury?
No!
This bruise looks a little familiar…
Gu Sibei thought for a moment and came up with an answer.
The shape of the bruise was the same as the heater at the crime scene!
After school started, the school gradually removed the heater in the classroom and replaced it with two floor-to-ceiling air-conditioning units.
The music classroom was rarely used, so the original heater was kept.
Judging from the extent of the bruise on Li Tao's arm, it was a new injury.
The school didn't allow employees to leave the school until the weekend.
Unless…
Li Tao went to the music classroom!
"God Gu? God Gu! Are you looking for something again?" Shayi turned around and saw Gu Sibei staring blankly ahead. She quickly went over.
"I'm fine." Gu Sibei smiled.
Gu Chen looked at Gu Sibei with appreciation. This kid could tell too. Interesting!
Then, he quietly noticed Li Tao's flustered expression.
Seeing that Li Tao was fine, Xiao Liu greeted him and left in a hurry with another policeman.
Shayi's mind was filled with the characteristics of the murderer that Gu Sibei had just mentioned. She was so careless that she didn't notice anything wrong with Li Tao.
Seeing Li Tao put the lunchbox in front of his computer on the rest table, Sha Yi immediately walked over.
He smiled and patted Li Tao's shoulder." Big Brother, you're really fast. Since you're back, hurry up and help us adjust the surveillance camera again.”
"We did as you said and didn't touch the machine in this room at all. We definitely can't let you be punished! Let's hurry up, we're in a hurry!”
Li Tao was so frightened that he trembled. He quickly replied," Hey, hey, I'll adjust it immediately."”
"From yesterday afternoon until today afternoon before the end of class, we'll play all four screens at the entrance of the teaching building, the hall of the teaching building, the stairs on the first and second floors.”
After Gu Sibei finished speaking, he pulled out a chair and sat beside Gu Chen.
Shayi gasped." Oh my god, 24-hour surveillance. How long do we have to watch?"!!”
