Crack, Crack.

In the corner of the living room of Room 2084, the camera placed on a tripod was shining with light. The technicians in the criminal technology room were busy collecting evidence.

There was almost no place to stay indoors. Officer Wang Fengnian stood in the corridor with a decisive 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 deliveryman uniform arrived at the 20th floor at 15:43 pm. He first knocked on the door of Room 2082, talked with a young man for more than ten seconds, and went to Room 2084, and in the name of delivering takeaway, the victim Zeng Weiming opened the security door."

A young operator reported: "After the security door was opened, the man quickly covered Zeng Weiming's mouth, entered the house, and brought the security door with him. Until 19:24, Officer Wang, Officer Wang, no one had entered and exited Room 2084 before you opened the security door.

The on-site appraisal results of the forensic team showed that the suspects should have murdered two victims from 16 to 17 o'clock, and climbed down from the 20th floor at around 18:30, leaving the community gate at 18:48.

There are no relevant orders for Room 2084 in the takeaway system, and the suspect is wearing a motorcycle helmet and mask with a fake license plate. It is difficult to identify the identity during surveillance. We have contacted the traffic management department to see if we can find the motorcycle the suspect is riding.

As for the victim's family, we are in touch as soon as possible."

Officer Wang nodded, looked at his home number, and felt scared.

The suspect prepared a fake motorcycle license plate in advance and printed out a fake takeaway order note. The methods were cruel and ferocious, clean and neat, without making any noise, and also made anti-reconnaissance measures.

This seems to be a premeditated crime of vendetta, but before knocking on the security door of Wang Fengnian's Room 2082, the suspect also took a look at the takeaway note - that is to say, the suspect is likely to have the mentality of harming one or the other, and wants to try it out with 2082 before murdering Zeng Weiming and Wang Fangni in Room 2084 to warm up.

It was almost the same as the most brutal suspect murdered his daughter...

The young operator said: "The only person who has met the suspect head-on is the classmate of your daughter, Officer Wang. Now the criminal technician is doing a job of sketching and restoring the suspect's portrait with him."

Wang Fengnian nodded, "Go and have a look."

Officer Wang opened his security door and saw his wife and daughter hiding in the bedroom and whispering to each other. The acquaintance who was walking the dog together the day before was gone, but the next day was so unacceptable.

Li Ang sat in the living room, wearing a gray-brown deer hunting hat on his head and a bottle of yogurt in his mouth. He found Wang Congshan's paintings with a triangle bracket from somewhere. While pondering, he quickly painted on the bracket drawing board with a pencil.

The young technician who was supposed to conduct criminal sketches sat next to him and looked at Li Ang's painting with curiosity.

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

The technician was startled, "Sorry, Team Wang, this young comrade can sketch himself, and his skills are very good, so I just let him draw it by himself."

"You can still sketch?" Wang Fengnian cast doubtful eyes.

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

"This painting is ACADEMIC academic style. I used to learn about the sketches of French copperplate painter Bernard Romain Julien for a while,"

Li Ang casually explained: "If time allows, I can also imitate Leng Jun's hyperrealism to use a colorful oil painting version."

Look, you can do it.

Wang Fengnian took a sketch. The man in the picture had a huge body, deep wrinkles on the eyebrows, thick and long fingers in gloves, and black boots covered with mud.

The characters' helmets, clothes, gloves, pants, and boots all extend a long line, pointing to some Taobao product words.

"The suspect is planning a crime, with clean and neat means and extremely high psychological quality. He is likely not a deliveryman. His uniform, gloves and boots are quite new, and it is very likely to be purchased on an online shopping platform. The sales of deliverymen's uniforms on the online shopping platform will not be too high. Collecting order numbers within six months, combining the order numbers of gloves and boots with similar styles, and comparing them with each other, can greatly narrow the range of suspects."

Li Ang said: "If the suspect is out of anti-reconnaissance awareness and has really joined the delivery staff before, then you can also compare the travel situation of the delivery staff in Yin City that day to find out all the people with criminal conditions. You can even find the list of delivery staff who have been fired for a long time in the past and find the shareholders of delivery staff who meet the requirements.

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 mailed to different foreign addresses, and then integrated to Yin City - in that case, the search will be much more difficult."

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

"Interests and hobbies." Li Ang replied seriously: "When we were in elementary school, our school often held various publicity conferences, such as drowning anti-drowning publicity conferences to invite drowning wronged souls to give speeches, and at the criminal law publicity conferences to invite death row prisoners to give speeches,

I have wanted to be a glorious police detective since then."

God invited the drowning soul and the corpse specimens to give a speech. Is your school a primary school writing Laoshan Taoist temple?

Wang Fengnian, who was feeling a little bit fucked, had already begun to adapt to Li Ang's brain circuit running rhythm, but just nodded and said nothing.

Li Ang sighed in his heart. Despite the slogan that murders must be solved, Li Ang was still pessimistic about the possibility that police officer Wang Fengnian could capture the suspect.

No matter whether the murderer is a monster, a ghost or a player, his whereabouts are strange and changeable means are not something that Police Officer Wang can deal with. If the murderer is a player, his anti-reconnaissance skills will be full. There are posts on the player forum that teach anti-reconnaissance skills to help players learn to hide their identities and hide their traces.

I just hope that Officer Wang can use official resources and find more clues.

Li Ang thought to himself, looking at Wang Fengnian with a fiery gaze, which made the latter feel furious.

"...... Go and record the transcript." Officer Wang asked his subordinates to put away the sketch.

After driving Li Ang to the police station to record the transcript, Wang Fengnian took Li Ang home again. After learning that he was alone, he specifically reminded him to pay attention to safety in the past few days. During this period, police officers would secretly protect him to prevent the crazy criminal suspect from attacking the witness.

Li Ang nodded in a slight way, opened the door and entered the room. Before the light was turned on, he saw a head with long hair hanging from the ceiling.

Chai Cuiqiao, who was hanging upside down on the ceiling, stretched out her palm and said in an ethereal and resentful voice: "I promised to come back soon? Let's play with me-mobile-phone-"

You are so tall, you are so beautiful. Li Ang took out his smart phone and shook it in front of Chai Cuiqiao, and said in a deep voice: "Go out with me tonight. I have something to do. After the matter is done, I will buy you a new one."

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