Click, click.

In the corner of the living room in Room 2084, a camera on a tripod flashes brightly. Technicians in the forensic technology room are busy collecting evidence.

With little room to stay, Officer Wang stood in the corridor with a grim face and talked to his colleagues about the progress of the case.

"According to the surveillance records of the elevator and the surveillance cameras in the corridor, a man wearing a yellow and black delivery man uniform took the elevator to the 20th floor at 15:43 in the afternoon, first knocked on the door of room 2082, talked with a young man for more than ten seconds, went to room 2084, and asked the victim Zeng Weiming to open the security door in the name of food delivery."

A young operator reported: "After the security door was opened, the man quickly covered Zeng Weiming's mouth, entered the house, and closed the security door until 19:24, Officer Wang, no one entered or exited room 2084 before you opened the security door.

According to the results of the forensic team's on-site identification, the suspect should have murdered the two victims at 16 to 17 o'clock, and climbed down from the 20th floor through the water pipe on the side wall of the balcony at about 18:38, and left the gate of the community at 18:48.

The takeaway system did not show the relevant orders for room 2084, and the suspect was wearing a motorcycle helmet and mask with a fake license plate, which was difficult to identify in the surveillance, and we have contacted the traffic management department to see if we can find the motorcycle that the suspect was riding.

As for the families of the victims, we are in contact as soon as possible. ”

Officer Wang nodded, glanced at his house number, and was afraid for a while.

The suspect made a fake motorcycle license plate in advance, printed out a fake takeaway order note, and the methods were cruel and vicious, clean and neat, without making any noise, and also did a good job of anti-reconnaissance methods.

This seems to be a vendetta-type premeditated crime, but before knocking on the security door of room 2082 of Wang Fengnian's house, the suspect also deliberately glanced at the takeaway note - that is to say, the suspect is likely to have the mentality of harming one more and one by one, and wants to use 2082 to try his hand and warm up before murdering Zeng Weiming and Wang Fangni in room 2084.

Almost, just closely, the murderous suspect murdered his daughter....

The young operator said: "The only person who has seen the suspect in front of him is Officer Wang, your daughter's classmate, and now the forensic technician is working with him to sketch and restore the portrait of the suspect." ”

Wang Fengnian nodded, "Let's go and have a look." ”

Officer Wang opened the security door of his house and saw his wife and daughter hiding in the bedroom and comforting each other - the acquaintance who had been walking the dog together the day before was gone the next day, which was really unacceptable.

Li Ang, sitting in the living room, wearing a gray-brown deer hunting hat on his head and a bottle of yogurt in his mouth, turned out Wang Congshan's triangular stand for painting out of nowhere, and while groaning, he quickly drew on the drawing board with a pencil.

The young technician, who was supposed to be doing criminal sketching, sat next to him and watched with curiosity as Leon painted.

The corners of Wang Fengnian's eyes twitched, "Xiao Zhang! What are you doing?! ”

The technician was taken aback, "I'm sorry Team Wang, this little comrade can sketch himself, and the technique is very good, I just let him draw it himself." ”

"You can also sketch?" Wang Fengnian cast a suspicious gaze.

"I understand a little." Li Angzi took a sip of yogurt, and turned the painting stand with a smile, even if Wang Fengnian didn't know how to sketch, he could roughly see that the lines of the portrait were clear, very regular, and the details were perfect, not like a quick sketch, but like a work of art in a gallery.

"This painting is in the ACADEMIC style, and I used to study it for a while from the sketches and portraits of the French copper engraving painter Bernard Romain Julien,"

Li Ang casually explained: "If time permits, I can also imitate Leng Jun's hyperrealism in a color oil painting version." ”

Look at what you can.

Wang Fengnian took the sketch, and the man in the mask on the picture was huge, with deep wrinkles in his eyebrows, thick and long fingers wearing gloves, and black boots stained with mud.

Next to the characters' helmets, clothes, gloves, pants, and boots, a long line is derived, pointing to some Taobao product words.

"The suspect committed a premeditated crime, his methods were clean and neat, his psychological quality was extremely high, and he was most likely not a delivery man. His uniform, gloves and boots are all brand new, most likely purchased on an online shopping platform. The sales of delivery uniforms on online shopping platforms will not be too high, and collecting order numbers within six months, combined with the order numbers of gloves and boots of similar styles, and comparing them with each other, can greatly narrow down the scope of suspects. ”

Li Ang said: "If the suspect really joined the delivery worker before this time out of anti-reconnaissance awareness, then you can also compare the travel situation of the delivery person in Yin City that day and find out all the people who have the conditions to commit the crime." You can even look up a list of delivery workers who have been fired for a long time in the past and find eligible co-tenants of delivery workers.

Of course, the suspect has a strong sense of anti-reconnaissance, and it is also possible that his gloves and boots are purchased on different online shopping platforms and different accounts, mailed to different foreign addresses, and then integrated and sent to Yin City - in that case, the search will be much more difficult. ”

Officer Wang Fengnian was stunned, "Where did you learn these things?" ”

"Hobbies." Li Ang replied solemnly: "When I was in elementary school, our school often held various publicity conferences, such as the drowning prevention publicity conference to invite drowning souls to give speeches, and the criminal law publicity conference invited death row prisoners to give speeches on the corpse specimens soaked in formalin.

From then on, I wanted to be an honorable police detective. ”

Why did God invite drowned souls and corpse specimens to give a speech, is your school reading as an elementary school writing Laoshan Dojo?

Wang Fengnian, who was faintly a little painful, had already begun to adapt to the rhythm of Li Ang's brain circuit, but he just nodded and didn't say anything.

Li Ang sighed in his heart, although there was a slogan that the murder case must be solved, Li Ang was still pessimistic about the possibility that Officer Wang Fengnian could catch the suspect.

Regardless of whether the murderer is a monster, a ghost or a player, his whereabouts are strange and his methods are changeable, and it is not something that Officer Wang can deal with - if the murderer is a player, his anti-reconnaissance skills will also be full, and there are special posts on the player forum to teach anti-reconnaissance skills to help players learn to hide their identities and hide their traces.

I only hope that Officer Wang can use official resources to find more clues.

Li Ang said secretly in his heart, and looked at Wang Fengnian with a blazing gaze, which made the latter furious.

“.... Go take a note. Officer Wang asked his subordinates to put away their sketches.

After driving Li Ang to the police station to record the record, Wang Fengnian drove Li Ang home, and after learning that he lived alone, he specially reminded him to pay attention to safety these days, and during this time, there would be police officers to secretly protect him and prevent the frenzied suspect from attacking the witnesses.

Leon nodded kindly, opened the door and entered the room, and before he could turn on the light, he saw a head with long hair hanging from the ceiling.

Chai Cuiqiao, who was hanging upside down from the ceiling, stretched out his palm, and said in an ethereal and complaining voice: "How about coming back soon?" Play with me—hand—machine—"

You're so big. Li Ang took out his smartphone and shook it in front of Chai Cuiqiao, and said in a deep voice: "Go out with me tonight, I have something to do, and I will buy you a new one after the thing is done." ”

"New phone?" Chai Cuiqiao floated down from the ceiling, blushing, kneading the corners of her skirt, "I have no experience, and it's not impossible, as long as you're not afraid of the cold." ”

"What do you think about all day?" Li Ang said with a dark face: "Follow me to catch the murderer." ”
