Serious Crime Unit 1

Chapter 1116 Greed (9)
Unresolved second quarter

Genxia Village is located in the west of Jiangxi District, at the foot of Laishan Mountain, nearly 15 kilometers away from the city center. Many years ago, this village was a gentle hillside, with more than 1000 households scattered here and there. In the late 80s, villagers knocked down their bungalows one after another. Six to eight-story buildings have been built and rented out to migrant workers or businessmen. Therefore, the residents here are very mixed. Now there are more than 6 migrants living here.

Su Qidong, the landlord of No. 11 Lotus Lane, has just retired for two years. His wife died of breast cancer when he was 55 years old. He did not remarry. His son went to study in the United States. He is 36 years old and has not yet married, although he often urges her to do so. He quickly got married, but his son didn't listen.

He lives in a house he built himself. The house has 7 floors. He lives on the top floor and everything below the 6th floor is rented out to others. He is very leisurely and lonely. In addition to strolling around the village park, he occasionally hangs out with friends. After playing chess, he would go home and watch TV. He would cook, do laundry, mop the floor, and do housework to pass the time every day.

On the morning of July 2021, 7, he went to the vegetable market to buy vegetables and prepare vegetables for lunch and evening. When he walked to the 20th floor, he glanced at the iron door on the outside and found that it was not locked. The wooden door was also ajar, and he felt a little strange.

There is a young man named Jiang Nancong living on the 6th floor. He said that he is engaged in software development. He does not have to go to work every day. He only works at home. Part of his time is spent helping netizens upgrade games to make money, and sometimes he also makes money. He had been speculating in Bitcoin for more than three years. He told Su Qidong that he had earned several million yuan by speculating in Bitcoin, and persuaded him to speculate in Bitcoin as well, but Su Qidong was unmoved.

Su Qidong is an out-and-out farmer. Later, his farmland was requisitioned by the development zone. He turned from a farmer into a worker and worked as a worker on the assembly line for 20 years. Since he was good at learning new technologies, he was transferred to work in the laboratory of the factory and became a worker. A laboratory technician until retirement.

He can earn 9000 yuan in monthly rent, and the rent on each floor is 1500 yuan. His pension is 6000 yuan per month, a total of 15000 yuan. He is used to being thrifty, and can only spend 5000 yuan every month, leaving 10000 yuan. He has saved all his money, so he is not interested at all in stock trading, Bitcoin trading, futures and the like.

However, he likes to go to Jiang Nancong's room to chat. Although Jiang Nancong is not very eloquent, they can talk about many topics, especially national affairs. They talk the most about Taiwan issues and Sino-US relations.

Sometimes Su Qidong would invite Jiang Nancong to his house for a drink. After three rounds of drinking, Jiang Nancong began to use his eloquence. Compared with usual times, he became two people. He was eloquent, talking about international events and analyzing the politics of various countries around the world. , military, economy, and even the customs and customs of the people of various countries, as if he had traveled all over the world.From then on, Su Qidong looked at him differently, but he didn't expect that his mind was filled with so much knowledge.As a result, they became friends all year round.

Jiang Nancong mostly worked at night and slept during the day. It was only 8 o'clock in the morning, and his door was ajar, so Su Qidong felt strange.As he reached for the door, he shouted: "Xiao Jiang, Xiao Jiang, why did you get up so early today?"

But no one answered him. He opened the iron door, and then pushed open the wooden door. When the door was pushed open, he was shocked: he saw Jiang Nancong lying on the off-white marble floor of the living room, his body curled up, His face was pale with a hint of cyan, and there was a lot of blood flowing under his snow-white T-shirt, which was shocking!
Su Qidong felt that something was wrong and didn't know what to do, so he had to slowly approach him and reach out to touch his carotid artery. As a result, a chill came from his fingertips. He pushed Jiang Nancong, but there was no response. It was obvious that he had already Been dead for hours.Next to the body lay a single-edged dagger, stained with blood.

Su Qidong took a deep breath, tried to calm his racing heartbeat, and then took out his mobile phone and dialed 110.After the police officers asked him in detail about what he saw and the address, they told him to stay at the door and not let anyone in to avoid damaging the scene. They also advised him not to enter the scene again. They would immediately send criminal police to investigate.Su Qidong agreed.

20 minutes later, Jiang Yiming led the No. 1 crime team to the scene. They laid down the investigation steps, put on the equipment for the investigation site and entered the scene.The first person to enter the scene was Luo Jin. After a preliminary inspection of the body, he said to Jiang Yiming: "Captain Jiang, the person has been dead for a long time. Corpse spots and rigor mortis have formed. The spots are light and concentrated in the lower parts, indicating that The body has not been moved, this is the first scene, and the light spots on the body are caused by the loss of blood in the body of the deceased."

"How long have you been dead?"

"The deceased's corneas are still relatively clear. Judging from rigor mortis and corpse spots, he probably died between 0 and 1 o'clock this morning, about 8 hours ago. The deceased was hit in the heart by the murderer. I compared it with the dagger on the ground. A look at the wound confirms that the dagger is the murder weapon." Luo Jin raised an evidence bag with one hand and pointed to the dagger in the bag with the other.

"It seems that the murderer was very professional. The heart was protected by multiple ribs, but the murderer was able to kill the deceased with one knife."

"Yes, the murderer may be a doctor or a professional killer."

"Could it be suicide?" Jiang Yiming asked.

"It's unlikely. Suicides usually slit their carotid arteries or wrists. Very few people stab their own heart, and it's even more impossible if they can kill with one knife. If a suicidal person wants to stab his heart to achieve the purpose of suicide, he has to stab his heart a lot. It's going to be painful. I think it's a murder."

Zhou Ting used a video recorder to film the entire scene. Because multi-band light sources were used, the curtains were closed and the scene was dimly lit.

Wu Jiang was squatting on the pedal, using a multi-band light source to survey the floor.Jiang Yiming walked to him and squatted down and asked, "Old Wu, have you noticed anything?"

"The scene may have been cleaned, but there were two types of shoe prints left. One of the shoe prints was from a size 41 Crocodile brand leather shoe. This should belong to the landlord Su Qidong. I visually inspected Su Qidong's shoes when I came in. Height and weight, and he was wearing crocodile leather shoes. The other shoe print should be the murderer..."

"Didn't you say that the scene had been cleaned? Why are there still traces of the suspect's shoes?" Jiang Yiming asked doubtfully.

"I only said that the scene may have been cleaned, but I did not say that it must have been cleaned... The body was only two meters away from the living room door, facing the living room door. Both shoe prints were from the living room door to the deceased in a straight line. There are no shoe prints in other parts of the living room, why is that?"

"It means the murderer knew the deceased."

"Yes, the murderer knew the deceased. After he asked the deceased to open the door, he directly stabbed the deceased in the heart with a dagger. This shows that the deceased was unprepared. Otherwise, he would have subconsciously blocked the murderer's dagger with his hand. If the deceased resisted, he would definitely have It will leave scars on the hands, even a little scratch, which will be clearly displayed under multi-band light sources, but the hands of the deceased did not have any scars."

"How do you think the scene might have been cleaned by the murderer?"

"The deceased was wearing slippers, and the pattern on the soles was almost polished. They were shoes designed for indoor use. It was impossible to find out which floor tile the deceased had walked on. However, there were traces of being wiped with a mop or towel in areas where there were no shoe prints in the living room. , so I think the murderer may have cleaned the scene, of course, it is also possible that when the deceased was cleaning the living room, the murderer came in and stabbed the deceased fatally."

"Even if the site has been cleaned, there will still be tiny biological samples left behind, such as hair, sweat stains, dander, etc. You and Xiao Ke will investigate carefully, and I will go find the landlord to question." Jiang Yiming walked out of the site and was in charge at this time Wen Xiaorou, who was inspecting nearby monitors, returned.

"Team Jiang, there are only two roads outside the scene. One road is Lianhua Road. There are surveillance cameras within 80 meters of both ends of this road. The other road is Huagu Road. It is connected to Lianhua Road from west to east. Huagu Road There are also monitors within 70 meters of the road, and the scene is surrounded by monitors, forming a secret room. The murderer must go through these three monitors to enter the scene and commit the crime."

"Since there is a security monitor, it must be connected to the city bureau. You and Yingying go back to the team first to check if any suspicious people have entered the periphery of the scene at the time of the crime. I know this requires a lot of effort, but this is a tried and tested method. Method." "Okay." Wen Xiaorou thought: No. 11 Lianhua Lane is far away from the main street and is very remote, and the time of the crime was between 0:1 and [-]:[-] in the morning. There should be very few people entering the periphery of the scene, so the work is not difficult. .

Jiang Yiming questioned Su Qidong and learned from him that the deceased's name was Jiang Nancong. He was born on May 1998, 5. He lived in Room 5, Building 124, Mingzhu Community, No. 15 Linhu Road, Jiangnan District. He was still unmarried because of his relationship with his parents. No, he moved to Su Qidong's house.

His parents were mainly opposed to him not going to work, not falling in love, not getting married, and spending all day playing computer games. So whenever he came home, his parents would nag him about his marriage, which he couldn't stand. , so I rented a remote house and lived a homebody life all day long, ordering all my meals online.

It stands to reason that this kind of person will not offend others. He only indulges in the virtual world and makes money from the Internet.Su Qidong said that he rarely interacted with Jiang Nancong except during dinner time, because Jiang Nancong worked at night and slept during the day.

At nearly noon, everyone had finished investigating the scene, and the body collectors transported the body back to the Municipal Bureau's Forensic Medicine Center.After lunch, Jiang Yiming called Jiang Nancong's father and told him that his son was killed in a rental house in Genxia Village. His father's name was Jiang Shuiming, and he worked as a sales manager at a food company called Liuyuelou.

After receiving Jiang Yiming's call, he didn't believe it at first, then was shocked and angry, and finally burst into tears... This kind of crying always made Jiang Yiming sad. A young life was murdered, as long as he has a conscience Everyone feels sad.

Twenty minutes later, Jiang Shuiming's driver drove him to the Municipal Bureau's Criminal Police Team to find Jiang Yiming.Jiang Yiming took him to the forensic center to identify the body.After he saw the body that had not been put in the freezer, he kept shaking his head, completely disbelieving that his living son had turned into a corpse.

Seeing him shaking his head, Jiang Yiming thought that the deceased was not his son, so he asked: "Mr. Jiang, isn't the deceased your son?"

"Yes... it's my son... But, I don't believe he will be lying here... Who killed him? I must avenge my son, even if I risk my life!" he bit out. , his face was livid, and he looked terrible.

"It is up to us to avenge Jiang Nancong. Please believe in the ability of the No. 1 Crime Squad. The first priority for you and your wife is to take care of your health and get rid of your sorrow as soon as possible. After all, people cannot be resurrected, so please take care of yourself." ." Jiang Yiming comforted him patiently.

He didn't answer, he didn't know what he was thinking, and tears kept flowing.His driver was supporting him and silently comforting him.Jiang Yiming told him that in order to find out the murderer, an autopsy must be performed. Did he agree?He nodded in agreement.

Luo Jin's autopsy report came out the next day, and everyone sat in the small conference room for a case analysis meeting as usual.Everyone does not have the heavy pressure in the past, because this kind of direct murder case is relatively easy to solve. It is not as complicated as remote control killing, timed killing, drug killing, and accidental killing. As long as you find out who has the motive for killing, and then Just ask for the suspect's alibi.

Lu Yingying and Wen Xiaorou were sitting together, whispering, and they didn't know what they were talking about. Jiang Yiming glanced at them and said, "Everyone is in a meeting. The autopsy report has come out. The deceased Jiang Nancong was stabbed in the heart by a single-edged dagger at the scene. Death caused by hemorrhagic shock, the time of death was between 7:20 and 0:1 on July [-], please express your own opinions." Jiang Yiming did not let Luo Jin speak first this time.

"There are no signs of damage to the two main doors at the scene. Anti-theft nets are installed on the windows of two bedrooms, a living room, a kitchen and a toilet. There are no signs of damage to the anti-theft nets. Therefore, I think the murderer is a relative or friend of the deceased. Or an acquaintance." Xiao Ke said.

"Xiao Ke is right. We extracted three fresh fingerprints on the wooden door of the living room. After comparison, one of them belongs to the landlord Su Qidong, the other fingerprint belongs to Jiang Nancong, and the third fingerprint is unknown. It should belong to the murderer, but there was no successful match in the fingerprint database, so the murderer should be a first-time offender," Wu Jiang said.

"Old Wu, are the shoe prints correct?" Jiang Yiming asked.

"Two types of shoe prints were extracted on site. After comparison, one of them was Su Qidong's and the other was unknown. However, we extracted another half of the shoe print. This half of the shoe print was close to Su Qidong's. Next to the shoe print is the second half of the shoe print. The front half of the shoe print was damaged by Su Qidong's shoe print. This half of the shoe print is blurry and it is impossible to determine what size of shoe was left." Wu Jiang answered.

"Why is the pattern of the shoe print blurred?" Zhou Ting asked.

"One is because the pattern on the soles has been smoothed; the other is because the shoe prints have been wiped but not wiped clean, so half of the shoe prints are left. Oh, there is another reason. The owner of the shoe prints is There have been cases of shuffling before, and the murderer intended to interfere with police investigations, but this method is rarely used by criminals."

"Are there any fingerprints on the murder weapon?"

"There are fingerprints left by five fingers on the murder weapon, and some only have half a fingerprint left, but the fingerprints of the index finger and middle finger are complete and clear. These two complete fingerprints also appeared on the wooden door of the living room at the scene, because the wooden door It has been painted, so the fingerprints are very clear. I think the owners of these two fingerprints are highly suspected of murder." Wu Jiang looked at Jiang Yiming and said.

“Can the suspect’s height and weight be determined from the suspect’s shoe prints?”

"Yes, the suspect is wearing size 41 sneakers. The comparison results are Nike shoes released in the summer of 2019. The suspect is about 170 to 174 centimeters tall and weighs about 55 kilograms. The error will not exceed 2.5 kilograms."

"Is there a number on the dagger? Can you find out where it came from?"

"No, the murderer made a homemade dagger out of steel bars, but it is very sharp. In order to make it easier to hold the dagger, the murderer installed a wooden handle on the front end."

"Yingying, have you discovered anything?" Jiang Yiming turned his head slightly and looked at Lu Yingying and asked.Lu Yingying is the leader of the visual investigation team, so Jiang Yiming will ask her first.

"The monitors on Lianhua Lane in Genxia Village were installed by the Genxia Village Police Station and are connected to our municipal bureau. We checked the surveillance videos taken by the three monitors during the incident, but no suspicious people were found. We are ready to expand the surveillance. Maybe you’ll find something during the video recording.”

"Okay, you continue to check the surveillance video. Let's investigate Jiang Nancong's social background and look for the suspect starting from the motive of the murder. Jiang Nancong is a otaku, and his social background should be relatively simple. I believe this case will not be too difficult. ." Jiang Yiming said confidently, but this time he made a mistake in judgment, and the case was much more complicated than he imagined.
