Serious Crime Unit 1

Chapter 1163 Death of Professor (10)
"Officer Wu, I haven't been out for half a month. Even when I buy groceries, I have them delivered to my door by Meituan's delivery guy, or I order food from 'Ele.me'."

"Do not you have to work?"

"I work at home, drawing comics for Qidian.com, QQ Reading, and Novel Reading Network. I have to work at least 12 hours a day, and sometimes I don't even have time to go to the toilet. I also paint oil paintings in my spare time. I draw comics for life. I paint oil paintings to realize my lofty ideals. I vow to become a painter like Van Gogh and let people all over the world appreciate me, respect me and worship me!" There was a special light in his eyes, just like a drug addict entering after taking drugs. Like the world of bliss.

"Young people, it's a good thing to have ideals, but you can't live a messy life... Tell me where you were at that time." Wu Jiang felt that people like him were simply blindly confident, unlike people who exist in real life, but I couldn't bear to pour cold water on him.

"Didn't I say that I haven't been out for half a month? How many times do you want me to repeat it before you can understand it?" He was a little impatient and wanted to drive them away.

"If you lie, you will be held legally responsible!" Xiao Ke said loudly. He really couldn't stand his bad attitude. This kind of person is not a lunatic, but at least half a lunatic. There is no need to be polite to him.

"I don't care. If you have the ability to arrest me, I can still be a painter in prison!" He and Xiao Ke were tit for tat.

"If you commit murder, you will most likely be sentenced to death. How can you be allowed to live in prison?"

"What evidence do you have to prove that I killed someone?" He tilted his head at Xiaoke, and Wu Jiang waved his hand to Xiaoke, signaling Xiaoke not to get involved with him.

"Who can prove that you were at home when the crime occurred?" Wu Jiang asked.

"I don't have a wife or children, and my parents don't live with me. No one can prove that I am at home. The only thing that can prove that I am at home is: I go to the Qidian Chinese website at 11 o'clock every night to update anime."

Wu Jiang knows that this kind of proof is useless, because online articles and online animations can be set to automatically upload.He didn't say anything, and walked out of Huang Weijun's living room with Xiaoke, and then went to the property management company to learn about the distribution of monitors in the community.

They learned from the property manager that a monitor is installed in front of the gate of each house. There are 88 houses in the community, each house has 7 floors, and the gate is the only entrance and exit.So, they called up the surveillance video at the time of the crime, but the surveillance video showed that from 2 pm to 20 pm on February 8, Huang Weijun was not seen entering or leaving the 12th gate.

The surveillance camera only captured the lights in Huang Weijun's home, but did not find him in the house because the curtains were drawn on the windows and doors facing the surveillance camera.If Huang Weijun had left home a few days earlier, hid elsewhere, and turned on the lights in the living room, it would have given people the illusion that he was at home.After he killed Liang Xuan, he fled the scene, hid outside for a few days and then returned home, so that he could evade detection.

Wu Jiang had no choice but to copy the surveillance video from February 2th to 15th to a USB flash drive, bring it back to the team, and show it to the visual investigation team.However, Wu Jiang intuitively believed that Huang Weijun was unlikely to kill Liang Xuan. First, the visual investigation team did not find him in the surveillance video in the lobby of Wenxin Building; second, Huang Weijun was tall and thin, with a pale face and a very weak appearance. To describe it, he might not have the strength to strangle Liang Xuan with one hand. Of course, this is not absolute, because some people are very good at pretending.

After the visual investigation team checked the surveillance video at the gate of the 10th building where Huang Weijun lives, it was found that Huang Weijun had not come out since he entered the house on February 2, and the door to the rooftop of the 13th building was locked. The keys are with the property management company.Therefore, Huang Weijun’s suspicion can be temporarily ruled out.

All clues are broken.Jiang Yiming believed that it was necessary to investigate the 28 people who entered and exited the lobby during the time of the crime, because there was a high probability that the murderer was among these 28 people.So, they divided into two groups, took the heads of 28 suspects, and visited the residents of Wenxin Building one by one.

Wu Jiang and Xiao Ke visited the residents from the 1st to the 14th floor, and Jiang Yiming and Zhou Ting visited the residents from the 15th to the 28th floor. They visited for a day. In addition to two families who went out for travel and business, they visited a total of 110 families and selected them. Find a suspect.

这个嫌疑人是乘电梯直达28楼的，时间是2月20日22:20:25，而28楼的四个住户都说不认识嫌疑人。他于23:05:55，从28楼进入电梯，一直到1楼，中间没有遇到任何人。

What was he doing on the 28th floor?Jiang Yiming thought that after taking the elevator to the 28th floor, he took the stairs to the 22nd floor and tricked Liang Xuan into opening the door and letting him in. Liang Xuan should know the suspect, and the food he bought might be used to entertain the suspect. Of course, Liang Xuan did not expect that The suspect actually came to kill him.

However, the suspect was wearing a large mask and glasses with large rims. It was unclear whether he was short-sighted or intentional.Lu Yingying took screenshots of the video and processed it with software. Although the avatar was clear, she could not recognize him.Lu Yingying had no choice but to input the avatar into the computer and use three-dimensional restoration technology to scan and reconstruct the avatar. In this way, the obscured face could be restored. However, because the suspect had very few exposed facial features, the three-dimensional reconstruction was There is a gap between the face and the person, and the similarity can only reach about 80%.

Another stupid way is to call up the surveillance video of the suspect along the way. However, if the suspect lives far away from the crime scene, or in another city, the workload will be very heavy. The visual investigation team has 6 people. , it took many days to check the surveillance video to find out where the suspect came from.

If the suspect comes from a certain village, it will be difficult to find the suspect even if you know that the suspect lives in this village, because many villages do not have monitors installed. In short, monitors are not omnipotent.

Jiang Yiming asked Lu Yingying to upload the suspect's profile picture to the police website so that police officers across the province could help find him.So Lu Yingying uploaded the suspect's approximate age, height, weight and profile picture to the police communication system.Judging from his height and body shape, the suspect is most likely the murderer, because in the surveillance video he appears calm, calm, and has strong steps, like an athlete or someone who has received professional training.

Police Communication is an information management system required for public security police to conduct mobile policing, also known as mobile policing system.It provides an information basis for the handling of emergencies and emergencies, can avoid the occurrence of major cases, and creates information conditions for the rapid detection of emergencies.It is suitable for all types of police personnel such as civilian police, traffic police, patrol police, criminal police, and security police, making the public security officers even more powerful when handling cases, and effectively improves the informatization level of the public security system.

Then Lu Yingying led the visual investigation team to search the traffic surveillance system along the suspect's path to see where he came from.Jiang Yiming, Zhou Ting, Wu Jiang and Xiao Ke took the suspect's profile picture and visited Liang Xuan's relatives, friends and colleagues to see who knew the suspect.

Wu Jiang and Xiao Ke went to Liang Ying and asked if they knew the suspect?Liang Ying said that she had never seen this person before.Wu Jiang told her to think carefully, which was crucial to solving the case.However, after thinking for a long time, she still shook her head and said she didn't know him.They had no choice but to ask Liang Xuan's other relatives and friends.

Jiang Yiming and Zhou Ting went to ask Qin Dong. After seeing the suspect's photo, Qin Dong said: "I seem to have seen this young man somewhere, but I can't remember it for the moment... I'm sorry, I may not have seen him, because A friend of mine is kind of like him.”

"Your friend? What's his name? What's his occupation?"

"His name is Susie. He is my college classmate and now works as an engineer at Liuying Chemical Plant. But he doesn't know Professor Liang. How could he become a suspect? And he is an honest and conscientious nerd. I can fight for him. Guaranteed, he won’t kill anyone.”

"People are unpredictable. Do you have any photos of him on your phone? If so, bring them up for us to see." Jiang Yiming thought for a moment and said.

"Yes, the sun was shining brightly on the Lantern Festival this year. I went to Dome Mountain Park with a few classmates for a picnic. There were 6 people in total, three boys and three girls. After eating skewers, we stood under the thousand-year-old yew tree in the park. Take a photo, look." Qin Dong handed the phone to Jiang Yiming.

Jiang Yiming looked at their group photo carefully. There were three girls in the front row. They were all squatting on the ground. There were three boys standing in the back row. Qin Dong stood in the middle and Su Xi stood on the right. His height was about 166 centimeters, because Qin Dong is 172cm, they form a good contrast.

Jiang Yiming used his thumb and index finger to stretch Su Xi's face to the limit and found that he was only 70% similar to the suspect. Because the suspect was about 172 centimeters tall, he could be eliminated.Jiang Yiming returned the phone to Qin Dong and said that Su Xi was not a suspect.

At this time, Jiang Yiming's cell phone rang. It was Guo Yiqing, the director of Jiangnan Avenue Police Station. He pressed the answer button and asked: "Guo, long time no see. What advice can you give me?" Jiang Yiming joked politely.

"Captain Jiang, you are my leader, how can I dare to instruct you? You should instruct me... That's it, our police officers have discovered the suspect you have on the police pass. If you want to find the suspect, come here Our police station, he is the police officer of Feicui Community, and he said there is a person who looks very much like the suspect."

"Okay, we'll go find you right away." After Jiang Yiming hung up the phone, he said goodbye to Qin Dong, and drove to Jiangnan Avenue South Police Station with Zhou Ting.After arriving there, Guo Yiqing introduced film police officer He Wenwei to them.Jiang Yiming took out the suspect's photo and showed it to He Wenwei: "Officer He, is this the person you saw?"

"It's very similar, but I'm not sure he is the person you are looking for." He Wenwei is 28 years old. After retiring from the army, he passed the examination and entered the police station.
