Serious Crime Unit 1

Chapter 1142 Greed (35)
Lu Yingying walked into Jiang Yiming's office. He felt very happy every time he saw her, because it meant that she might find new clues. Lu Yingying was the leader of the visual investigation team, so any doubtful points found in the surveillance video would be handled by her. Come and report to him.

"Yingying, have you found any new clues?" Jiang Yiming asked with a smile. His smile was so bright, it seemed like there was honey in his mouth.Lu Yingying immediately realized that Jiang Yiming was in a very good mood, but she didn't know what the happy event was.

"Captain Jiang, your smile is very charming today. Is there something particularly happy for you?" Lu Yingying asked.

"Really? I've been practicing to keep my emotions invisible, but I didn't expect you to see it. I'm so dazzling... New clue?"

"Captain Jiang, you haven't answered me yet." She stood aside waiting for his answer without putting down her laptop. She was teasing him.She would occasionally act coquettishly in front of him, even though he was her leader.

"Well, I should share my joy with everyone. Wanqing is pregnant..."

"Ah! Great! Climbing snow-capped mountains, crossing grasslands, and walking on the [-]-mile Long March, I finally reached the Holy Land of Revolution. Congratulations! Congratulations! I'm going to be a father soon, and I want to treat you to dinner. Congratulations on your successor." She Really happy for him.

"Okay, after the 9 case is solved, I will invite everyone to have a feast at the Seaview Hotel." The Seaview Hotel is located in the middle of the Gold Coast, opposite the Coast Hotel. It is the best place to enjoy the sea view and is also a four-star hotel. The seafood there is unloaded directly from the fishing boats and is very fresh.

"Wow, wow, I love the Buddha Jumping Over the Wall over there. I'm going to give you a good meal this time! Back to the topic, we found a suspicious person in the surveillance video of Wolong Community. Please take a look at the surveillance video." She put down her notebook Turn on the computer, click on the player, and a surveillance video appears in front of you:

A man of about 30 years old, carrying a backpack made of soft fabric, walked from the corridor of the community to the lobby of Tianya Building, then walked to the right and disappeared from the surveillance video. It was 9:10 pm on September 1.On the right is the stairwell. He most likely took the stairs to avoid the surveillance video of the elevator.

"Yingying, why do you think this person is suspicious?"

"First, this person is wearing a mask and a cap. In the days when the new coronavirus is raging, it is normal to wear a mask. However, the season has entered the white dew, the sun is not so hot, and wearing a cap is not normal; second, in his backpack The capacity of the bag is exactly the size of a bottle of wine. Judging from the appearance, the bag contains something rectangular. Third, he chose to take the stairs instead of the elevator. The main reason is that the elevator monitor is closer to him, so, He chose to climb the stairs, but the only regret was that there was no monitor installed in the stairs; fourth, he left Tianya Building 41 minutes later, which was just enough time for him to open the door, exchange wine at Feng Zhiyu’s house, and climb the stairs."

"So many of the conditions are very consistent with the suspect's characteristics. That's great! Can you restore his face?"

"No, I've tried it with the software. His face is covered by an extra-large mask. However, access to Wolong Community is relatively strict. Visitors need to register their detailed identities. You can go to the duty room at the door to find the person's identity. "

"Has the suspect's height and weight been calculated?"

"After calculation, this person is 168 to 170 centimeters tall and weighs about 70 kilograms. The surveillance video was taken during the day. The suspect's clothes, pants, shoes, and gait are all very clear, so I don't think it is difficult to find him. .”

"I'm just afraid that he bribed the security guard on duty. You should know that a pack of good cigarettes can bribe the security guard. Even a few flattering words from a beautiful girl can bribe the security guard, so that someone can go in without registering a detailed identity. People with fake ID cards." Jiang Yiming said.

"I used the suspect's exposed face to make a three-dimensional portrait. However, it may not be realistic. However, the general outline is clear and close to the suspect's true appearance." She picked up the mouse and clicked on the icon on the desktop to see the portrait of the suspect. appear before your eyes.

The suspect has a thin face, high cheekbones, deep eye sockets, small and lively eyes, fair skin, thick lips, and half-long hair. He looks a bit like Jay Chou and is quite handsome.

"There are four gates in Wolong Community, southeast, northwest and northwest. Are there monitors on these four gates?"

"Yes, we are checking which gate the suspect entered through. If the suspect climbs the wall and enters, he cannot be photographed. The perimeter of the community wall is about 1.8 kilometers. There are many surveillance blind spots within this 1.8 kilometers."

"Is there any surveillance video in the corridor from the elevator on the 12th floor of Tianya Building to Feng Zhiyu's house?"

"No. You know that the more monitors you install, the higher the cost. There are already 500 monitors in the entire Wolong Community. There is no need to install such dense monitors."

"We assume that the suspect climbed in through the fence, then he will definitely leave shoe prints or fingerprints on the fence. I have seen the fence there. It is made of light green wall paint. The wall paint has good traces. Carrier."

"Yes, the next step is up to you. Our visual investigation team is checking the surveillance videos of the four gates of Wolong Community. I believe there will be results soon." After finishing speaking, Lu Yingying put away her laptop and went out. She suddenly looked back and said with a smile. , "Don't forget to treat us."

Jiang Yiming asked Wu Jiang and Xiaoke to inspect the wall of Wolong Community, both inside and outside, to see if the suspect climbed the wall and entered the community.He and Zhou Ting took the suspect's three-dimensional photo and screenshots of the surveillance video to visit the security guard on duty at the time.

Wolong Community is located at No. 21 Huangsha Road, Jiangdong District. Turn from Jiangdong Avenue into Feiying Road and walk to the end of Feiying Road to reach Wolong Community.This community is relatively close to the city center and the Gold Coast. You can enjoy the sea view if you live in a high-rise building, so the housing prices are very high and the security conditions are also very good.

Jiang Yiming and Zhou Ting entered from the north gate. The gate was blocked by a smart barrier. The security guard at the gate refused to let their car in. Of course, the security guard didn't know it was a police car. Zhou Ting parked the car at the door, got out of the car and walked into the security room. , handed the ID to the security guard, and then he realized that he had offended the criminal police officer of the city bureau and quickly apologized to him.

"There's no need to apologize. We're here to find someone. What's your name?" Zhou Ting asked.

"My name is Lu Liangshan. I have only been working here for half a year. I don't know you, so..." He was still full of apologies.

"If a stranger comes to visit, do you need to register identity information?"

"This is necessary. We will not let them in without registration status or the owner does not call us to explain. Otherwise, our wages will be deducted, and in serious cases, we will be fired." Luliangshan is tall and thin, 30 He is about [-] years old, with a dark complexion and rough skin, like someone who has been working outdoors for many years.

"Do you want to sign in when you go to work?"

"Of course. We have to clock in and out of work. We work in three shifts. There are two people in each shift. They are mainly responsible for guarding the gate and are not responsible for patrolling the community."

"Then you should know who is on duty at 10pm this month, right?"

"Of course we know. We signed in with our fingerprints, which are entered into the computer system and stored permanently. If you want to know who was on duty at that time, you have to check the records on the computer to find out." His voice was loud and clear.

"Then please turn on your computer and check who was on duty at that time."

"Okay." He walked to the desk, sat down on the executive chair, turned on the computer and started checking. Since there was a specific time, he quickly found out that Lu Liangshan and Wei Linsheng were on duty at that time.

"Were you on duty at that time?"

"Yes."

"Look, do you know this person?" Zhou Ting took out the screenshots and photos of the suspect and handed them to him.

"I don't know. Is the person in the video screenshot and the photo the same person?"

"Yes. Please take a look at the surveillance video captured in the lobby of Tianya Building in your community." Zhou Ting took out the tablet computer from his bag and opened the surveillance video for him to see.

After watching the surveillance video, he said: "I know this person. He has no registered identity information. He is a friend of Wei Linsheng. He said that Feng Zhiyu invited him to drink. So, we let him in. He also gave us every One pack of Furong King cigarettes per person.”

"Are you sure? What's his name?" Jiang Yiming suddenly became excited.

"Yes, it's him. I asked Wei Linsheng, but I don't know his name or where he lives."

"Since he is Wei Linsheng's friend, Wei Linsheng should know where he lives, right? You call Wei Linsheng here, we want to question him."

Lu Liangshan took out his cell phone to call Wei Linsheng, but the phone was turned off.Lu Liangshan felt strange. Normally Wei Linsheng would not turn off his phone, and he never said he wanted to resign. How could he turn off his phone?Lu Liangshan called the security captain to ask about Wei Linsheng's whereabouts. The security captain said that Wei Linsheng resigned three days ago.

When Jiang Yiming heard this, his heart trembled: Will Wei Linsheng be silenced?Wei Linsheng had to be found quickly, so Jiang Yiming called Lu Yingying and asked her to locate Wei Linsheng's cell phone immediately.After a while, Lu Yingying called Jiang Yiming and said that Wei Linsheng's cell phone appeared in Room 1 of the Royal No. 203 Hotel.Jiang Yiming called Wu Jiang and Xiao Ke and told them not to investigate the wall because the suspect had been identified, and asked them to go to the Royal No. 1 Hotel to look for him.

When they arrived at the hotel room 203, a man named Qian Hao was sleeping. He found four criminal police officers standing in front of him and asked curiously: "Why are you looking for me? I haven't broken the law."

"What's your name?" Jiang Yiming saw that his figure and appearance were 80% similar to the suspect in the surveillance video, which was extremely suspicious.

"My name is Qian Hao."

"Why is Wei Linsheng's cell phone on you?"

"He went back to his hometown in Sichuan. He wanted to buy an iPhone 12, so he sold the phone to me. Is this wrong?" he asked calmly.

"We suspect that you are related to a murder case. We need to ask you to go to the Municipal Bureau's Criminal Police Team. Let's go." Jiang Yiming felt that he looked harsh but was weak at heart.

"Murder? That's ridiculous. Who am I murdering?" he said with a sneer.

"Feng Zhiyu! You know it all, stop pretending. Let's go." Jiang Yiming motioned to Xiao Ke and Zhou Ting to take him away by force.He wanted to resist, but his hands were tightly held by the two of them and he couldn't move at all. He could only struggle pointlessly. In the end, he felt that his actions were futile and had to give up.

After Qian Hao arrived at the criminal police team, Jiang Yiming put him in the interrogation room.Discuss with everyone how to find evidence of Qian Hao's murder.Wu Jiang said: At present, the fastest way is to identify good money through his gait.Because gait, like fingerprints, is exclusive.

So, Wu Jiang and Xiao Ke asked Qian Hao to walk several times in the interrogation room, film his gait, and analyze it with a gait meter. Because Qian Hao went to Wolong Community at 9:10 pm on September 1, the surveillance video , so they had a comparison object. They input the gaits on the two surveillance videos into the gait meter for comparison, but the result was disappointing: the people who went to Wolong Community on the afternoon of September 9 were not rich!
After listening to Wu Jiang's report, Jiang Yiming felt incredible: "Old Wu, did you make a mistake in the comparison?"

"Absolutely impossible. If you look with your eyes, you may make a mistake, but if you use a gait meter to compare, it is impossible to make a mistake. Human movement is the rhythmic contraction of more than 1000 muscles controlled by the nervous system, driving more than 200 bones to rotate around The result of coordinated movement of more than 100 joints. The similarity between the two recognition results is less than 40%."

"Is there any way to change the gait?" Jiang Yiming felt that Qian Hao was playing tricks, and based on his many years of criminal investigation experience, he believed that Qian Hao was the murderer.

"Well... your question made me suddenly realize: Qian Hao may have worn a gait correction device when he went to the crime scene to exchange for Wuliangye wine on the afternoon of September 9, thus changing his gait. Today he is not wearing a gait correction device. gait, so his gait is completely different from the gait when he went to the crime scene. He is really a cunning guy!" Wu Jiang suddenly felt a chill on his back, because in the past they often used gait recognition equipment to convict suspects, so , will anyone be wronged?The judge will accept the results obtained by the gait recognition device as strong evidence.

"What if Qian Hao denies wearing a gait corrector?" Jiang Yiming asked.

"Aren't there Lu Liangshan and Wei Linsheng who can testify? Even though they didn't see Qian Hao's face, they heard Qian Hao's voice." Xiao Ke rushed to answer.

"The problem is that Lu Liangshan and Wei Linsheng did not see Qian Hao enter Feng Zhiyu's house to exchange Wuliangye wine. Qian Hao could admit that he went to Wolong Community at that time, but did not admit that he exchanged the wine in Feng Zhiyu's wine cabinet. If Qian Hao had not thought of it, his lawyer I can think of this problem." Jiang Yiming believes that these evidences can only prove that Qian Hao went to Wolong Community at that time, but cannot prove that he exchanged Feng Zhiyu's Wuliangye wine.

"Yes, at 9:10 in the afternoon on September 1th, the sun was very bright, and Qianhao had to climb 12 floors. He would definitely be sweating, and when he went into the house to change Wuliangye wine, he would be nervous, so, definitely He will be sweating all the time, and the DNA of the three body fluid samples we extracted from the scene did not match in the database. I think among these three body fluids, there should be money and good sweat." Xiao Ke said excitedly.

"Well, this is a good idea. First, pay him to extract biological samples, make his DNA, and then compare it. Once the comparison is successful, there will be ironclad evidence. First, there are two witnesses, Lu Liangshan and Wei Linsheng; second, there are two witnesses: Lu Liangshan and Wei Linsheng; There is surveillance video; third, there is his DNA at the crime scene, which has formed a complete chain of evidence." Jiang Yiming patted Xiaoke on the shoulder and praised him.

Luo went into the interrogation room, extracted Qian Hao's saliva, and immediately used it for DNA comparison.At the same time, Jiang Yiming invited Lu Liangshan to the criminal police team and asked him to listen to Qian Hao's voice and identify Qian Hao's body shape and appearance.At first glance, Lu Liangshan was sure that Qian Hao was the person who said he was going to find Feng Zhiyu that day. After hearing his voice, he was even more sure that it was Qian Hao.

Jiang Yiming found Wei Linsheng through the Chengdu Shuangliu District Criminal Police Team. He admitted that Qian Hao said he was going to find Feng Zhiyu on the afternoon of September 9, and said that he was carrying a rucksack with something in the shape of a wine bottle when he came out. Afterwards, the wine bottle was still in the backpack.

The next day, Luo Jin made Qian Hao's DNA and took it to the evidence library for comparison. Sure enough, it matched the sweat DNA collected from the crime scene, which showed that Qian Hao had been to the crime scene.When everyone heard about it, they finally breathed a sigh of relief.Because tomorrow is the National Day Golden Week, and Luo Jin and Ye Jiayin will hold their wedding at the Coast Hotel on October 10th.If the murderer hadn't arrived, everyone might not have been able to attend Luo Jin's wedding, let alone have a holiday.

"Good money, tell me, why did you murder Feng Zhiyu?" Jiang Yiming, Wu Jiang and Lu Yingying were interrogating him.

"What evidence do you have to prove that I murdered him?" he asked in a strong-armed tone, his hands trembling slightly. He tried his best to stop the trembling, but he couldn't. After all, this was a life-and-death situation.

"Will we come to interrogate you without evidence? Do you know Feng Zhiyu?"

"No. How could I know him?"

"Then have you been to his house? For example, went to his house to steal?"

"I'm an upright gentleman, and I never do any sneaky things. I don't know where his home is."

"Very good. This is what we are waiting for. Let me ask you one more thing. Where were you at 9:10 pm on September 1th?"

"How can I remember something that happened so long ago?" He pretended to be confused while trying to stay calm.

"But Lu Liangshan and Wei Linsheng, the security guards of Wolong Community, both testified that you walked into Tianya Building and walked from the stairs to the 12th floor, carrying a small backpack with something like Wuliangye wine in it. After 41 minutes, You came out again, and the surveillance video there proves that."

"I was wearing a big mask..." He suddenly realized that he had made a mistake, which was tantamount to admitting that he had gone to Wolong Community, so he stopped quickly.

"Although you were wearing a big mask and a peaked cap, Wei Linsheng is your friend. Not only did he recognize you, but he also let you in without registering your identity information. This is a witness that cannot be refuted. There is more than one certificate.”

"I just went there, what can you do to me? Can't I just go there and play?"

"Of course it's okay to play, but not to kill people. We collected sweat at the crime scene, made DNA, and compared the DNA of your saliva together. The results were exactly the same, which means you climbed 12 floors Floor, you were sweating profusely. When you entered the crime scene, your sweat kept flowing due to nervousness and fell to the ground. With this key piece of evidence, you will be doomed and narrowly escaped death. Now we will give you a chance to confess, and the judge will consider the verdict. You have a reprieve from death. If you refuse to confess, the death penalty awaits you, so think about it carefully."

When he heard about the money, his mind went blank, his whole body was shaking, and he couldn't stop at all. Big beads of sweat broke out from his forehead. He was extremely desperate... He weighed it for a long time and finally confessed his murder motive.

It turned out that Qian Hao met a beautiful girl on the Internet, whose online name was Xinruo Fireworks. After chatting with her for a while, he felt that Xinruo Fireworks suited him very well. He soon fell in love with her and also had a video chat with her. , of course this is a fake video produced by Feng Zhiyu.As a result, the two quickly fell in love.

Next, Xinruo Yanhua used various reasons to borrow money from him, saying that her mother had chronic nephritis and needed a lot of money for treatment. If she had no money, she would have to wait to die.She often cried to him, and because of the video chat, he believed her. Over the past two years, he sent her 35 yuan, spending all his savings. Not only that, he also borrowed 10 yuan from a friend and remitted it to her. .

He kept asking her to meet, but she used various reasons to shirk it. Finally, he finally realized that he might have been deceived by her, so he asked a friend to check her IP address, but he could not find it because her IP address Encrypted.

Later, she asked him to buy her a birthday gift, so he used her trick and bought her a gold necklace to send to her. He followed the courier to the door of her community. Unexpectedly, a man came to collect the courier. He was Feng Zhiyu. He felt extremely insulted, and it turned out that the person he was dating was an ugly man several years older than him.

From then on, he vowed to kill him, otherwise, it would be difficult to relieve the hatred in his heart.So, he started following him and found out that he was a network engineer and also knew where his family lived.He discovered that he loved drinking Wuliangye wine, so he bought dimethylmercury on the dark web, injected it into Wuliangye wine, and then rubbed his fingerprints on Feng Zhiyu's door and asked someone to copy them online. Model of his fingerprint.

On September 9th, he saw Feng Zhiyu and his wife going to work, so he put on a gait correction device and got to know Wei Linsheng and asked him to let him in. So, he walked into Tianya Building and climbed up the stairs for 10 seconds. Building, he used a fingerprint model to open the door of Feng Zhiyu's house, sneaked in, and changed the wine in the wine cabinet. As a result, Feng Zhiyu was finally killed by him, and he was extremely happy.He will never regret killing this scumbag!This is what happened.

"Why didn't you call the police? Let the police catch him. Isn't it tantamount to committing suicide?"

"Police? There are at least millions of scammers in China. Have the police caught them all? Haven't you heard the shameless words of the scammers: There are too many fools in China and not enough scammers. I believe in myself more. I think the only way is to let him down. Only hell can relieve hatred. Even if the police catch him, they will only sentence him to one or two years in prison, which will not relieve his hatred at all."

Jiang Yiming sighed deeply, not knowing what to say.As long as human beings exist, scammers cannot be eliminated, no matter how many police officers are there, it will be useless. This is a very real thing.
