Serious Crime Unit 1

Chapter 805 The Death of the Criminal Police Captain (4)
Cheng Guihui is a very generous person. His income is no worse than those of the bosses. He has a 7-story house in Guanxia Village, with each floor of 120 square meters. The first to sixth floors are rented out. He and his wife Wu Fang lives on the 1th floor. The monthly rent for each floor is 6 yuan, totaling 7 yuan. With a salary of 2500 yuan, the annual income is more than 15000 yuan.He also works as a consultant for several security companies. This money is gray income and it is difficult to calculate clearly, so he has a lot of capital.

Judging from the activities that night, Qu Dalin was the most suspect. He might have appeared at the dinner to get close to Cheng Huihui, because the other three people were Cheng Huihui's friends for many years, and it was unlikely that he would betray him.

Qu Dalin made his fortune by selling liquefied petroleum gas. He was a liquefied petroleum gas dealer in Linhai Town, Jiangbei District. Even though it was just a small town, it had a population of nearly 8, so it brought him a steady stream of income. When he was young, He hung out in the underworld, and then slowly became a small businessman with a legitimate reputation.

Therefore, Jiang Yiming took Zhou Ting to visit Qu Dalin first.

Linhai Town is located in Jiangxi District, adjacent to Tianyuan Village. Zhou Ting turned the car from Jiangxi Avenue into Huanghua Road. Linhai Town is on the edge of Huanghua Road. Qu Dalin’s store is in Block A on the first floor of Linhai Building. The store is spacious and bright , the decoration is also relatively high-end, as if it sells electrical appliances instead of liquefied gas.

Qu Dalin is tall, about 187 centimeters, with relatively regular facial features, but the skin on his face is rough, and his eyes are sharp, making him look a bit fierce.He was sitting behind the cashier in the store. When he saw them walking in, he quickly stood up from his chair to greet them: "Captain Jiang, where did the strong wind bring you here today?"

"Since you know me, I don't want to be polite..."

"The two police officers are heroes in the hearts of the citizens and our patron saints. Who doesn't know you? Come, come, come, please sit down and I'll make tea for you." He said with a smile.

"There's no need to make tea, I'm in a hurry to handle the case... You should know about Cheng Gui's murder, right?"

"I know, his wife even called me to scold me for inviting him to the Night Cat Nightclub for a drink, which led to the murder of captains. Where is this? If I knew he would be killed that night, I wouldn't waste those unjust accusations. Money. I spent almost 1 yuan that night." He seemed a little distressed.

"He is not on duty now and has no power. Why do you ask him to do it?"

"You can't say that. He is not on duty, but his apprentice is. One of my cousins ​​got into a fight with someone and gave him a second-degree minor injury. At the time of the incident, the Linhai Town Police Station dispatched police, and the police station handed over the case. To the Jiangbei District Criminal Police Team, we are preparing to file an investigation. We have reached a settlement agreement with the other party. The other party will not sue us because we paid the other party 80 yuan in compensation..."

"This matter will definitely be filed. Reconciliation is possible, but this is a criminal case and it is impossible to withdraw it."

"So, I want to make some accommodations through Captain Cheng, because the Criminal Police Captain is his apprentice. If he is willing to come forward, he should not be able to file the case."

"We don't care about this. We came here to be killed."

"What? Do you doubt that I have returned after killing Cheng?" He opened his eyes as big as a cow and looked at Jiang Yiming in disbelief.

"We don't suspect that you killed Cheng Huihui, and you couldn't have killed him, because when he died, you and Liang Yichang went to the Royal Bathing Center for a sauna. We suspect that you might have called the murderer to kill Cheng Huihui, because only you knew It’s time to come back home.”

"How could I do such a bad thing?" He looked very innocent.

"Firstly, we want to know about your relationship with Cheng Guilai; secondly, we want to know your call records that night. Of course, we can also go to the mobile company to investigate; thirdly, did you find anything special about Cheng Guilai that night? For example, being afraid, or drinking to drown your sorrows, etc.”

"First, Captain Cheng and I had just met, and there was no relationship; second, I only had one phone call with Liang Yichang that night; third, I didn't find anything unusual about Captain Cheng. He kept drinking with me and having fun. I'm very happy, except for us men, he refused all the wine offered by the lady." He answered very logically.

Jiang Yiming and Zhou Ting went to the mobile company to check Qu Dalin's call records and found that he had indeed only called Liang Yichang once that night.Lu Yingying then checked whether Qu Dalin had sent any information or emails through WeChat, QQ, and email backstage. The result was that he had not. Therefore, Qu Dalin's suspicion was basically eliminated.

Wu Jiang and Xiao Ke went to see Du Shaowei, the film policeman of Tianyuan Village, and asked him to go with them. Du Shaowei became a film policeman just three years after graduating from the police academy. He felt very lucky to be able to investigate the case with them. He especially admired it. Xiaoke is brave, good at fighting and not afraid of sacrifice.Du Shaowei said that Kaoshan Lane is a long alley leading to Laishan. There are 160 families living in it, with a permanent population of nearly 1000 and a larger floating population. Because there is no portrait of the suspect, he can only check the suspect's height and weight, and Qingshan Brand electric bicycle, this job is more difficult.

Wu Jiang judged from the surveillance video that the murderer was 170 centimeters tall and weighed about 55 kilograms. From the analysis of the murderer's gait, Wu Jiang believed that he was a middle-aged man who had been engaged in manual labor for many years, about 40 to 46 years old, more Like a farmer, of course, that's not accurate, but it's not a huge difference.

If the suspect's footprints can be extracted, they can be analyzed using a gait analyzer.Human movement is the result of the nervous system controlling the rhythmic contraction of more than 1000 muscles, driving more than 200 bones, and coordinating movements around more than 100 joints.So it has its own rules.

The gait analyzer is the most commonly used equipment for detecting macroscopic movements of human limbs. It mainly studies the technology and device for gait analysis through image processing of human movement images obtained by ordinary cameras.The content involves the detection and analysis technology of human body movement trajectory, ground support reaction force and surface electromyography signal, which is very practical in criminal investigation.Unfortunately, no traces of the suspect were found at the scene.

Many middle-aged and elderly people were sitting at the entrance of the backing alley, chatting, playing cards, and chess. Wu Jiang asked more than a dozen people if they had found any suspects and suspect cars that met the requirements. One of them, a recently retired man, said that he had seen this car and rode it. The person driving the car looks very similar, and seems to live at the other end of the alley, but I don’t know which family.

The uncle lived at the entrance of the alley and was a local. He did not recognize the cyclist, which meant that the suspect was from out of town. He was only renting here temporarily. They felt that this person was suspicious, so they came to the bottom of the alley. They wanted to ask someone, but there was no one there, so they had to knock on the door of a landlord.

The person who opened the door was a young woman in her 30s. Wu Jiang handed her the simulated photo of the electric bicycle and the suspect. She thought for a moment and said: This cyclist seems to live in House 74, but she can’t. affim.

After they thanked her, they went to the door of House 74 and rang the doorbell. The doorbell rang for a long time before someone asked through the intercom: "Who are you? Who are you looking for?" His voice was hoarse, old, and breathless, like Be a sick person, or an elderly person.

"Are you Uncle Huo? I am Du Shaowei, the policeman from Tianyuan Village. I know your son Huo Lai. Could you please open the door? We need to know the situation from you."

"Come up." After the door lock rang, the door opened automatically. Du Shaowei knew that Huo Lai lived on the sixth floor, so he went straight to the sixth floor. His footsteps were light and agile, and he soon arrived at the sixth floor to greet him. Theirs was Huo Lai and his father.

After entering their home, Huo Lai invited them to sit down and drink tea. Wu Jiang said he didn't have time to drink tea, so he handed him pictures of people and cars and asked him if there were any tenants' electric bicycles like this in the house?After seeing the photos, he said that there was a tenant on the first floor who had a Qingshan brand electric bicycle.

Because Huo Lai was only about 165 centimeters tall, Wu Jiang had already ruled him out. The suspects in the surveillance video were accurately calculated by computer, and the error would not exceed 2 centimeters.

As soon as Xiao Ke heard that the suspect lived on the first floor, he immediately said to Wu Jiang: "No, if we woke up the suspect when we called the door downstairs, he might have run away by now. I really regret not staying downstairs." Guard.”

"Don't worry, he can't run away. There are surveillance cameras everywhere now, and some places even have facial recognition monitors installed. Where can he run away?" Wu Jiang comforted Xiao Ke, looking very confident, "If you are worried, , you go and wait at the suspect's door first," Xiao Ke went downstairs after hearing this.

Wu Jiang asked Huo Lai to take out the copy of the suspect's ID card and show it to them. Huo Lai turned around and walked into the room, opened the drawer, searched for a while, found the copy of the suspect's ID card, and then handed it to Wu Jiang , Wu Jiang said he wanted to borrow this copy, and Huo Lai agreed.

Wu Jiang looked at the copy and thought that the bareheaded photo on the ID card looked a bit like the outline of the suspect, so he asked Huo Lai to go downstairs with them and help call the door. After Huo Lai hesitated for a while, he seemed a little reluctant, but in the end he decided Go downstairs with them.

Huo Lai quickly called away the man named Xie Xiangyun. It was already 9:30 in the morning and he was still sleeping. He was woken up from his sleep. When he saw the police looking for him, he was very surprised, but he didn't Ask them why they are looking for him. Maybe he thinks silence is golden?
Xie Xiangyun is nearly 170 centimeters tall and weighs about 60 kilograms, but this does not mean anything because the suspect will intentionally wear thick clothes and pants, and sometimes deliberately wear height-increasing shoes, in order to interfere with the police's handling of the case.Of course, this situation is relatively rare because height-increasing shoes are difficult to move around.

"Xie Xiangyun, we are here to understand the situation from you. You must cooperate with us."
