Serious Crime Unit 1

Chapter 1157 Death of Professor (4)
Jiang Yiming returned to the criminal police team. As soon as he walked into the office, Wen Xiaorou knocked on the door and came in. She sat opposite Jiang Yiming and said, "Captain Jiang, Xiao Xi from the visual investigation team and I went to Liang Xuan's house and found the instruction manual for the Rock brand electronic lock. and serial number, connected it with Bluetooth and electronic lock, and read the data at the time of the crime... cough..." Wen Xiaorou stopped and patted her white throat with her hand.

"Do you have a cold? If you have a cold, you should go to the hospital for examination. If you get COVID-[-], don't infect everyone." Jiang Yiming said seriously.

"How could I let the new coronavirus invade my body? Don't worry, I went for a nucleic acid test after work yesterday, and I went to get the test report this morning, which proved to be negative... At the time of the incident, Liang Xuan drove a total of four Second door, these four times, Liang Xuan opened the door from the inside to allow people to enter the scene."

"Oh? That means four groups of people entered Liang Xuan's home during the time of the incident?"

"This is not necessarily true. What if Liang Xuan goes out to throw away garbage? Or what if he goes out to collect express delivery? One thing is strange. The Rock Smart Lock can be set up for face recognition and can open the door remotely, but Liang Xuan has not set up face recognition. With only fingerprint recognition set up, facial recognition is supposed to be faster and more convenient.”

"Perhaps everyone has different habits and understandings. Is there any way to remotely hack into the door lock?"

"Of course there is a way, but you need to know the serial number of the door lock. However, I have checked it on the computer and there is no trace of hacker intrusion. Captain Jiang, have you gained anything?"

"No, we only did a preliminary investigation. One of the suspects is Shen Hui, the director of the research institute. I analyzed his micro-expressions and found that he must have lied to us, and he has an affair with Liang Xuan. contradiction."

"Can you also recognize micro-expressions? Tell me, let me learn, learn." Wen Xiaorou became interested.

"I also learned it from the psychology experts in the bureau, and I only learned trivial things... The human face is composed of 43 expressive muscles. People can lie, but the muscles on the face cannot, and the true inner reactions will pass through. The momentary subtle muscle movements are shown, especially the movement of the eyes and the size of the corners of the eyes...this is micro-expression."

"What micro-expressions of Shen Hui made you think he was lying?" Wen Xiaorou asked carefully.

"When Shen Hui answered the question, he shifted his eyes, leaned back, and took a deep breath. This was an escape reaction, indicating the fear and uneasiness in his heart. At the same time, he covered his chest with both hands and turned sideways, indicating that he was a This is a protective reaction, he is uneasy and protecting the secrets in his heart... Of course, what I learned is only 1% of the polygraph's identification ability."

"Wouldn't it be quick and easy to bring a portable polygraph to conduct interviews and investigations in the future?"

"Naive! First of all, we can't randomly test polygraphs on people we visit; secondly, polygraphs are not omnipotent. Do you remember the Du Pei Wu case?"

"Of course I know. This is a huge injustice that shocked the whole country. On the morning of April 1998, 4, at No. 22 Guotong North Road, Kunming, the police found two bodies of a man and a woman in a minivan. The man was Shi Lin. Wang Junbo, deputy director of the County Public Security Bureau, and policeman Wang Xiaoxiang, who was Du Peiwu's wife, had a relationship before his death and were shot to death at close range. The police suspected that Du Peiwu had killed them both to vent his hatred, so they arrested Du Peiwu. Torture was used to extract a confession, and Du Peiwu finally confessed and was sentenced to a suspended death sentence. Later, the real murderer was caught, and Du Peiwu was acquitted by the court on July 40, 2000."

"You have a good memory. Do you know why Du Peiwu, who is also a policeman, was tortured by the criminal police to extract a confession?"

"The main reason is that the investigators invited polygraph experts to conduct a polygraph test on Du Peiwu, and the results proved that Du Peiwu lied... I understand. You want to tell me: polygraph detection is not omnipotent. Why didn't I know this?" Wen Xiaorou rolled her eyelids up, showed a teasing smile, and then walked out of the office.

Wen Xiaorou is playful and cute, like a breeze that purifies the dull and turbid air, while Lu Yingying is calm and steady, more like the Dinghai Shenzhen.

Jiang Yiming and Zhou Ting went to the community where Qin Dong and Shen Hui lived to check the surveillance video.The monitoring facilities in their community are very complete. Although they do not cover all blind spots, monitors are installed at the main entrances and exits. By checking the surveillance video, it is proved that Qin Dong is not lying, because there is a monitor at the door of his house.

而沈辉则说谎了。沈辉住在江北区维也纳小区14栋12楼，电梯和大堂的监控录像表明：沈辉于2月20日20：05，开着自己的宝马车向市中心驶去，直到21日凌晨01:10才回家。沈辉为什么要说谎呢？难道他是凶手吗？
Jiang Yiming and Zhou Ting went to find Shen Hui again. Shen Hui saw the clues from Jiang Yiming's unhappy expression and felt uneasy, but still very politely invited them to sit down for tea and talked while drinking, acting very calm. "No, Shen Hui, why did you lie to us? Do you know the consequences of perjury to the criminal police? Don't think that we can't do anything to you because you are a deputy department cadre. Let me tell you, even if the provincial party secretary breaks the law, we He can be brought to justice. Tell me, where did you go in your BMW on the night of the 20th?" Jiang Yiming asked coldly. He had no patience for hypocritical people like Shen Hui.

"I'm sorry, I'm sorry, Captain Jiang, I was wrong. I didn't expect you to check the surveillance video of our community... I can't help it if I lie... Well, originally this was top secret, but in order to cooperate with your work, I I can only tell the truth. I just ask you not to make this matter public, otherwise, my future will be ruined in your hands..." His forehead was sweating. The weather was not hot, and the indoor temperature was about 21 degrees. Warm as spring.

"It depends on what you are going to do. If you break the law, we will not tolerate it. If it is not serious, we can let you go. We also understand that it is not easy for the country to train a professor." Jiang Yiming saw that he would cooperate and his tone relaxed. .

"This... I actually couldn't help it. That day, Hu Yuanhai, the director of the Provincial Department of Science and Technology, called me and asked me to accompany him to take a bath at the Phoenix Bath Center... Alas, I know this is against the rules, but... Under the roof, I have to bow my head, our institute needs the policy support of Director Hu..." he said with a sad face.

Of course Jiang Yiming knew what the Phoenix Bathing Center was doing. It was a notorious prostitution venue in the city. Due to its membership system, it required introductions from influential people to join the club, so it was difficult for the police to find strong evidence.I heard that all the girls there are college graduates and must not be over 26 years old. Their faces and figures are all the best, as strict as a director selecting actors.The police raided it several times, but gave up because there was no evidence. The main reason was that the boss had a very strong background; secondly, there was a remote monitoring system, which could identify all the police officers in the city. Once a police officer came to the door, the system would The police were called immediately, and the ladies quickly put on waitress uniforms and disguised themselves well.

Jiang Yiming asked to see Shen Hui's driving recorder, and Shen Hui had no choice but to accompany them to the parking lot, open the car door, and show them the video captured by the driving recorder. The surveillance video showed that Shen Hui died at 20: 38 entered the Huihuang Building and walked out of the Huihuang Building at 00:28 the next morning. The Phoenix Bathing Center is located on the 36th to 38th floors of the building. At the same time, he saw Hu Yuanhai and Shen Hui coming in and out together.

Jiang Yiming and Zhou Ting drove to Phoenix Bath Center to check the surveillance video. The security manager said: In order to protect the privacy of the VIPs, they did not install surveillance cameras.After hearing this, Jiang Yiming was a little annoyed: "According to the regulations of the public security department, all large public places must install surveillance cameras. Why don't you listen?"

"I'm sorry, Captain Jiang, I don't know about this. You can ask the boss." The security guard replied matter-of-factly, seemingly not taking Jiang Yiming's words seriously.

Jiang Yiming didn't want to get into trouble with the security manager, so he and Zhou Ting went to the security department of the building to check the surveillance video. Because there were a total of 8 elevators in the building, all of which were equipped with monitors. There were also two monitors in the lobby of the building. Everyone who entered and exited the building. They had to go through these two monitors, so they copied the surveillance video in the lobby to a USB flash drive and brought it back to the team for review by the visual investigation team.

"Captain Jiang, should we report Shen Hui and Hu Yuanhai's visit to the Phoenix Bathing Center to the disciplinary inspection team?" Zhou Ting asked.

"Let's report it to the Bureau, and let him make the decision. Anti-corruption is not something we are responsible for. It depends on whether the Bureau wants to report to the disciplinary inspection team. The issue of an official's life style may be major or minor, so do him a favor. The road to anti-corruption is long, and our most important thing right now is to arrest the murderer of Liang Xuan."

Wu Jiang and Xiao Ke went to check on a man named Fang Zhou. Fang Zhou appeared in the surveillance video of the lobby of Wenxin Building and was the food delivery boy of "Ele.me".He is 26 years old, of medium height, and fits the physical characteristics of the murderer. Moreover, he got off the elevator on the 2nd floor at 20:21 on February 11.

"Fang Zhou, we are from the Criminal Police Team of the Municipal Bureau. We need you to cooperate with us in investigating criminal cases. Please tell the truth, otherwise you will be legally responsible." Wu Jiang asked Fang Zhou while sitting in the private room of "Red Maple Restaurant".

"Okay, I will definitely cooperate. What's the criminal case?" His face was red and dark, his eyes were bright, and he was sitting on a chair in work clothes with an uneasy expression.

"The male owner of Room 2204 of Wenxin Building was killed."

"Ah?" he exclaimed, "how could it be? He is a good man. He always gives me some fruits to eat. He said that fruits can replenish the water lost in the body, because I am often too busy to forget to drink. Water. He also often taught me to be a kind person, be a good person first, and then you can do good things... What a pity..." Tears flowed from his eyes.
