Notes From A Criminal Investigation 5 Chapter 8

Chen Yang pointed at Owen and said, "You still insist on saying this, you crow's mouth, take it back quickly. Last time, I said something unlucky, and now it has come true."

Owen followed the custom of the detachment and said "Puh, Puh, Puh" three times to the sky, which was considered to be taking back the unlucky words he had just said. Everyone knew that this method of "taking back unlucky words" was a bit nonsense, but everyone was willing to believe it, so they all adopted this method, which was considered a tradition of Jiangzhou Public Security.

Thirteen investigators from the Serious Cases Unit took four vehicles and arrived at the scenic Bayue Combat Training Base of Jiangzhou Public Security Bureau at 8 a.m. on March 17. At 9 a.m., the combat training base held an opening ceremony, and more than 200 police officers gathered on the playground. The spring class is more comfortable than the summer class. In spring, more than 200 police officers stood on the playground, feeling the spring breeze and the sun, which made people feel refreshed. In summer, the sun is scorching and the mountain wind is hot. Standing on the playground to attend the opening ceremony is really sour and refreshing.

The opening ceremony officially began. First, the national flag and the combat training base flag were raised. Secondly, under the leadership of the instructor representative, all the participating police officers reviewed the police oath and the training instructor representative took the oath. Thirdly, the principal of Bayue Combat Training Base gave a speech, encouraging all the trainees to obey arrangements and follow commands, and to develop the strong ability to be able to come when called, fight when they come, and win when they fight.

After the ceremony on the playground, the police officers moved to the lecture hall, where Director Gu of the Political Department of Jiangzhou Public Security Bureau convened a pre-training mobilization meeting for all the police officers. Owen sat in the first row, and next to him was Chen Haodang, a police officer from the Municipal Political Department.

At 11 o'clock, the opening ceremony ended. Chen Haodang followed Owen to the dormitory and joked: "The conditions at the base are simple. Are you used to living here?"

Owen said: "No matter how simple the conditions are, there are still two people in one room, which is better than the housing conditions at the School of Political Science and Law."

Chen Haodang said: "We were students then. Now it's different. It's hard to go from extravagant to frugal. Many police officers can't adapt."

Owen bared his teeth and said, "Do you have a misunderstanding about the living environment of our grassroots police officers?"

Chen Haodang did not answer the question directly, and said: "In the near future, I will be the deputy director of the Chengxi Police Station. I will probably be in charge of criminal investigation. If I encounter a case in the future, I will have to ask you for advice."

"It's pretty quick to become an official."

"We are the bricks of the revolution, we will be moved wherever we are needed. I haven't handled any cases since I started working, so I need to catch up now. You, the detective, need to give me some guidance."

"It's best for me and Team 1 not to show up. If we do, it will be a major case. An arson case just happened in Chengxi New Town, and Team Teng and the Second Major Crimes Team took over."
 
"Yes, I'm afraid I'll have to go down soon, just because of the arson."

At this point, Chen Haodang received a call and stood up subconsciously, saying, "Director Gu, I'm in the police dormitory, chatting with them and understanding their ideas about participating in combat training. OK, I'll come right over." After hanging up the phone, he sat on the bed again and said, "I'll have dinner with the leaders and go down the mountain after dinner. After I get to the west of the city, please come a few more times to cheer me up."

When Chen Haodang hurried out, Jiang Keyang hummed a song and entered the dormitory. The two did not exchange pleasantries, but just said hello. Knowing that Chen Haodang was going to be the deputy director of Chengxi Police Station, Jiang Keyang sat on the bed and sighed: "It is better to be close to the water and get the moon. The people around the leader are of high quality. The team leader has made great contributions many times, but he still holds a position without a staff. The deputy director of the police station is a real official leading cadre."

Owen was calm about this and said, "I don't care about so many things. Just do your own thing."

After the opening ceremony, the serious, intense, united and lively combat training life officially began.

After the first year of operation, the base launched two new systems in the new semester. The first is to combine police management with cultural education for police officers, start from the little things in life, establish a management log, implement the "three roll calls and three inspections" system every day, record the police officers' attendance, discipline, housekeeping and hygiene, etc. truthfully in the work log, and announce the conduct assessment every day; the second is to incorporate instructors into the training squadron, who not only undertake teaching tasks but also have management responsibilities.

At the same time, key students were selected to serve as deputy squadron leaders to cooperate with the instructors.

The two new systems are a supplement to the original system. After implementation, the police officers who participated in the training quickly changed from working status to combat training status. Owen, who graduated from Shannan Political Science and Law Criminal Investigation Department not long ago, quickly adapted to the management mode of the combat training base. The police officers who graduated a long time ago returned to the classroom-like environment and experienced the combat training life of "three roll calls and three inspections", and they all complained bitterly. In general, the front-line police officers often face danger and train more seriously. The non-front-line police officers are relatively lax and have a weaker sense of substitution during training.

On the morning of the fourth day of the training, the second squadron came to the playground. There were cushions on the playground, and a sturdy police officer with a big scar on his cheek was standing at the edge of the playground. Owen stood in the team and quietly winked at the instructor in front of him. This sturdy police officer was Fan Yong from the special police detachment, Fan Shaer who had worked in the 105 special task force. After the combat training base was established, Fan Yong was hired as an instructor at the base, mainly responsible for grappling and fighting training.

On the playground, Fan Yong wore an instructor's armband on his left shoulder, full of energy and spirit, and practiced Shannan Police Physical Grappling Boxing for the participating police officers. He has been training for a long time, and he is full of energy and agile, which won applause. After performing a set, he said in a loud voice: "Police officers should be rational, peaceful, civilized and standardized when on duty, and they should be supervised by the people. Therefore, verbal and bare-handed stopping of illegal and criminal acts that need to be stopped on the spot is very important. We pay attention to control when stopping criminal acts, and control ability is more important than striking ability. I used to have a colleague who was very good at anti-joint skills and often defeated the enemy with one move, but was scolded by criminals as despicable and shameless. We must have this kind of despicable and shameless ability, so that we can protect ourselves and control the scene. Please ask this student to step out."

Fan Yong was called Fan Sha'er in the 105th special task force and was famous for his bravery. Today's words made Owen feel that he should be looked at with new eyes after three days of absence. After being called by Fan Yong, he stepped out of the line and stood on the soft mat in the middle of the playground.

Fan Yong's eyes wandered among the students, and finally stopped at a tall man. This was a policeman from Changgui County, at least 1.85 meters tall, very burly.

After the burly man stepped out, he stood face to face with Owen.

Fan Yong said: "They are both strong men. If you don't have grappling and fighting skills, it's not easy to control each other with brute force. If you are proficient in grappling and fighting, the situation will be different. Now, you can try to control each other."

The police officer of Changgui County was a retired cadre of the army. He was strong and confident. After the instructor issued the order, he reached out to grab Owen's wrist. Owen had practiced the joint-locking technique, and he was quick-eyed and quick-handed. He grabbed the middle finger of the police officer of Changgui County in a flash and sank his body. The police officer of Changgui County was careless and lost the battle. Following Owen's action, he could only squat down and had no power to fight back.

Owen then let go of his opponent and took a step back.

Although Owen reduced his strength when arresting him, the Changgui County policeman still felt pain, shook his middle finger and glared at Owen.

Fan Yong had expected this result, and said in a loud voice: "Both students have good physical fitness and are evenly matched, but the taller student suffered a loss and his joints were captured. In fact, he was controlled. The student who captured the joints was my former colleague, Owen, who is often cursed by criminals and is the leader of the serious crime group of the Municipal Criminal Police Detachment. During the Spring Festival, he led his team to capture a murder fugitive in Jinjiang Temple. The fugitive was carrying a gun at the time, and if he did not have excellent grappling and fighting skills, the consequences would be unpredictable."

"sharp."

"Wow, Detective."

Most of the students had heard of the name of Owen, the leader of the Serious Crime Unit. When they learned that the student who was "grabbing the middle finger" was Owen, they could not help but sigh in admiration. The police officers of Changgui County worked in the Criminal Police Brigade. When they learned that the person in front of them was the leader of the Serious Crime Unit, they were convinced and no longer felt aggrieved.

After the training, Owen and Fan Yong got together.

Owen said: "You are really a fool. You chose a tall and strong opponent for me. If I can't beat him, I will be embarrassed on the spot."

Fan Yong smiled happily, the scar on his cheek trembling, and said: "In the special police detachment, there are only a handful of people who can beat me. To be precise, there are only two who can beat me. One is a retired special forces soldier, and the other is a former Sanda athlete. I really can't beat these two. In terms of combat effectiveness, I can rank third in the city. With my level, you can sneak attack me in the old criminal police building. The students I picked out look tall and strong, but in fact they have fat on their bellies and slow movements. They can't escape your claws at all. If I don't have the ability to judge people, how can I be the deputy captain?"
 
The 105th Task Force is a brand of the Jiangzhou Municipal Public Security Bureau. Owen and Fan Yong were both members of the first batch of the task force. They had been in the same trench and were very cordial when they met. There was no way to drink at the combat training base, so the two agreed to have a big drink after the training.

The Serious Cases Unit is responsible for investigating major cases in the city. It is the sharpest of the sharpest, and the probability of encountering danger is relatively high. It is very conscious in training. Owen served as the deputy squadron leader as a trainee. After discussing with the instructors, he often increased the training volume for the Serious Cases Unit and practiced the tactics of the assault and attack team in a targeted manner. After ten days, the tactics of the Serious Cases Unit have improved greatly and won unanimous recognition from the instructors at the combat training base.

When Owen was working in the 105th case team, he had repeatedly met members of the Criminal Police Brigade at case analysis meetings. When he first served as a team leader, he was an alien who broke into the first team and had a lot of estrangement from the investigators of the Serious Cases Team. But after experiencing the Wu Yu case and the Erdaoguai Black Bone case, and conducting combat training together, he gradually integrated into the group. Now, most investigators of the Serious Cases Team even regard the 105th case team as a department of the Criminal Police Brigade, similar to the Exploration Technology Room and the DNA Room.

There are bound to be some unpleasant things in the beginning of collective life, and there are complaints everywhere. However, every time the collective life is about to end, everyone will always miss the days of eating, sleeping and training together. Time flies, and it is March 28th in a blink of an eye. The training will end the next day.

After the participants had dinner, the Serious Case Team, led by Owen and the tactical instructor, went to the stadium to practice group tactics again, and did not return to the dormitory until nine o'clock. After returning to the dormitory, Owen took the time to take a shower, and then went online to check the emails sent by Zhou Tao. Zhou Tao sent the "Social Relationship and Behavior Trajectory Comprehensive Table" recently produced by the 105 Special Case Team for Qin Yong, Julian, Jin Chuantang, Zhang Jiahong and Li Xiaofeng. The investigation of the 105 Special Case Team during this period has generally reached a dead end. Zhu Lin, Wang Hua, Zhou Tao and Yi Sihua traveled to two provinces and four cities, and investigated and visited more than 20 relatives and friends of Julian and Yang Guojian. Julian's whereabouts came to an abrupt end after he disappeared, and there was no news until he was declared dead. There was no breakthrough in the investigation as a whole, and it can only be said that relevant information was collected.

After reading this email, another email came in with a simple content: Captain Zhu will go through the retirement procedures tomorrow.

Owen quickly called Zhu Lin and asked, "Master, are you retiring tomorrow?"

Zhu Lin said: "We will handle the formalities tomorrow."

Owen said: "After retirement, Master is still a criminal investigation expert employed by the bureau. I will still look for you if I need anything."

Zhu Lin said with a smile: "Retirement is a path that everyone must take. As long as you work, there will be such a day. If you need me, I am in good health and can go to the scene at any time."

After reading the email and making the phone call, Owen was in a slightly depressed mood. Before lights out, Jiang Keyang, who was chatting in the next dormitory, came back to chat with Owen for a while, leaning his head on the pillow, and his breathing became even. Owen sat in front of the window, looking up at the light moonlight outside the window, listening to the snoring of his comrades, and didn't want to fall asleep for a long time.

At 6:30 in the morning, the phone beside the bed rang. It was definitely not a good thing for the phone to ring at this time. Owen and Jiang Keyang woke up at the same time, turned over and reached for the phone. Jiang Keyang's phone did not ring, but Owen's phone rang.

After answering the phone, Owen said to Jiang Keyang who was getting dressed: "Hurry up, there is a case and we need to go to the scene."

Jiang Keyang had already buckled his belt and asked, "What case requires a team to go out?"

Owen said calmly, "Team Two is working on the arson case, Team Three is in Changsheng, and the new case is now the turn of Team One. Body parts were found on the Elephant Hill behind Jiangzhou College, and they were chopped into pieces. We have to leave early and cannot attend the graduation ceremony this morning."

Jiang Keyang but.toned up his clothes quickly and said, "The team leader went to the base to ask for leave. I'll go get Zhang Guoqiang and Du Feng."

Owen took out his notebook and wrote: At 6:10 am on March 29, body parts were found at Elephant Hill.

Soon, the three vehicles left the Bayue Combat Training Base and arrived at the Elephant Slope on the back mountain of Jiangzhou University fifteen minutes later.

The car arrived at College Street, and Owen and others walked along the college alley to the south entrance of Elephant Hill. Elephant Hill is one of the hills in the city, and it is named because the top of the hill is shaped like an elephant. Elephant Hill has a pedestrian walkway from south to north, connecting the college alley in the south and the central avenue in the north. There are many small paths like capillaries in the middle of the pedestrian walkway, forming a spider-like trail system on the hillside. Elephant Hill is a place for citizens to exercise. Every morning and evening, many citizens take a walk and exercise. Elephant Hill is also a famous lover's hill. It is easy to get to Elephant Hill from the back door of the college, and many student couples leave unforgettable memories here.

The pedestrian paths at both ends had been blocked by police officers from the Dongcheng Police Station. After showing their credentials, Owen and his companions walked up the mountain along the southern slope. After walking for a few minutes, they met Qian Gang, deputy director of the police station, and a young police officer.

Qian Gang did not exchange pleasantries, but said to the detectives from the Serious Case Unit, "Around 6:10, a young woman went up the mountain to walk her dog. The big golden retriever picked up a transparent plastic bag from the bushes and brought it to the young woman. The contents of the transparent plastic bag were all pieces of meat and a palm. The young woman was so scared that she could not walk, so she sat on the ground and called the police. I have arranged for the police to take her to the police station to take a statement."

The young policeman had a small mark of vomiting on his chest and his face was pale.

Qian Gang said self-deprecatingly: "We found three packages of body parts, each weighing from a few pounds to more than ten pounds. I guess there are still many body parts on the mountain. The murderer is a pervert. One package was intestines, which were neatly cut, tied with ropes, coiled together, and put in a plastic bag. The three policemen in our police station all vomited. I haven't seen such body parts for many years, and I almost vomited."

Owen asked: "How many bags did you find?"

"Three bags. According to the pattern of dismemberment cases and the weight of the bodies, there must be more body parts."

"Is the body part of one person or several people? Is Elephant Hill the place where the body was dumped or the scene of murder?"

"It's impossible to judge right now. I have to ask the station to send more people to block the north-south passages and clear out all the citizens on the hillside path." Qian Gang retched and called the station to dispatch reinforcements.
 
Owen and his companions walked up several dozen meters when their cell phones rang. It was Gong Jianmin who called and asked, "What's the situation at the scene?"

Owen said: "I just arrived at the scene and met Director Qian. The initial judgment is that this is a vicious dismemberment case. Three bags of body parts have been found so far, and there must be more on the hillside. The murderer dumped the body at night. The body parts were put in a plastic bag and thrown into the grass, which was relatively hidden. People who exercised in the morning did not find it, and it was later picked up by a dog. The entire serious case team is here, and we will immediately look for other body parts."

Gong Jianmin said, "I'm in a meeting at the municipal party committee and can't come for the time being. Team Chen will come soon. Team leader Teng and Team 2 Miao Wei are investigating the arson case. Team 3 Li Ming has work to do. Team 1 will handle this case. You will be in charge of the command. The dismemberment case has a very bad social impact and will definitely cause panic. We must solve the case as soon as possible and give an explanation to the victims and the people of the city."

Investigators from the Serious Crime Unit, police officers from the police station, auxiliary police officers and public security activists completely blocked both ends of the road leading up the mountain, no longer allowing pedestrians to pass, and then began to search for other body parts along the trail and check the citizens on the Elephant Hill trail.

Plastic bags containing body parts were constantly being discovered, with their locations marked.

Chen Yang, executive deputy chief of the Criminal Investigation Brigade, arrived at the scene with reinforcements.

Technicians began on-site investigation.

At the end of 2010, Jiangzhou Municipal Public Security Bureau reformed the criminal technology department according to the requirements of the superiors. Lao Tan was appointed as the deputy chief of the criminal police detachment and the chief of the sixth brigade (technical brigade). Five professional laboratories were established, namely the forensic laboratory, the trace inspection laboratory, the document and audio-visual material inspection laboratory, the physical and chemical inspection laboratory and the forensic evidence laboratory. The technical brigade also hangs the sign of the Municipal Public Security Judicial Appraisal Center, which is consistent with the past.

When Xiao Lin, director of the trace examination room, led technicians to investigate the scene, Director Li and Tang Liu from the forensic room, Zhang Chen from the DNA room and others also entered the core scene.

Old Tan walked around the core scene and returned to the small pavilion on the top of the hill. He said to Chen Yang and Owen, "We found nine bags of body parts on the mountain, but no head. From the body parts found, it was initially determined that the victim was a young man, and the victims were the same person. The murderer was very calm, and the body parts were cut along the joints, and the cuts were very neat. The plastic bags were of the same model, which were ordinary garbage bags used in daily life."

Chen Yang said: "This is the third case of dismemberment I have encountered since I joined the Criminal Police Detachment. Generally speaking, in murder and dismemberment cases, the criminals are often familiar with the victims. This is what we often call relationship crimes. The dismembered are mainly women. In this case, a young man was dismembered, which is relatively rare. There are several reasons for dismemberment. One is to evade investigation and hide the crime, which is similar to the act of burning the body in the Erdaoguai black bone case; the second is to vent inner anger through dismemberment; the third is to satisfy perverted desires. Only by finding the reason for dismemberment can we determine the direction of investigation."

Owen looked down at the scene, the location of the body parts appeared in his mind, and he said: "The murderer cut up the body, put the body parts in a transparent plastic bag, and threw them on the busy Elephant Hill without deliberately hiding them. The murderer is not trying to evade investigation, it is very likely that he was venting his anger, or he has a perverted mentality."

At this time, screams were heard from deep in the forest. A couple hid in the deepest forest of Elephant Hill. After the police began searching, they followed the trail to play hide-and-seek with the police, preparing to shake off the police and leave Elephant Hill to avoid trouble from the police. Unexpectedly, a head was seen hanging under a big banyan tree on a remote trail. The breeze blew, and the head was shaking gently. The facial features seemed to be shaking, especially the mouth opening and closing, as if it was talking.

The girl was so frightened that she turned pale and crawled into her boyfriend's arms. The boyfriend was a fool and brave. He was very curious when he saw the head, so he quickly took out his camera and took a few pictures.

"Don't take pictures, it's scary."

"I'm a medical student. I've dissected a lot of corpses, but I've never encountered one in the wild."

"So perverted, I'm scared."

The boyfriend had a strong desire to protect his girlfriend. After taking a photo, he hugged his girlfriend and walked out of the alley. When he saw two policemen, he pointed behind him and said, "There's a head hanging over there."

One of the two policemen was Yan Feng, and the other was Tan Daguo. Tan Daguo was looking for people along the path, and Yan Feng stopped the couple and asked them to accept the investigation and not leave for the time being.

When the investigators arrived at the scene, in addition to investigating the scene, they also had an important task to investigate the people at the scene and find the suspects. The couple was most afraid of being in trouble with the police, but they did not expect to be blocked by the police and cried out in bad luck.

Tan Daguo soon saw the head hanging on the banyan tree, and hurriedly called Inspector Zhang Guoqiang, and then stayed at the place where the head was hung.

Zhang Guoqiang and the director of the investigation room, Xiao Lin, arrived at the same time. Xiao Lin kept taking photos, and the auxiliary police officer who assisted in the search squatted nearby and vomited.

Owen received the call and rushed to the place where the head was hung from the top of the slope as fast as possible. On the banyan tree, a human head was hung by a white plastic rope, and there were a few drops of blood under the head. The victim had been killed for six or seven hours, and his deformed facial features still retained an expression of anger and fear.

Owen looked up, took a deep breath, and said, "Xu Hai!"

Chen Yang, who was following behind him, panted and said, "He is Xu Hai, are you sure?"

Owen said with certainty: "It was Xu Hai. Emma had dealt with him before, and I have met him many times."

Qian Gang followed closely behind Chen Yang, took a look at the head, turned his head, retched several times, and said: "Yes, it's Xu Hai. Xu Hai is well-known in the area. He has r@ped and molested girls many times and has been taking pictures of women's skirts on Golden Sky Street for a long time. He was not yet fourteen years old when he committed the crime, so he does not bear criminal responsibility and has been at large outside."

Chen Yang stared at the head and said, "I know about Xu Hai's bad deeds. Is he fourteen years old now?"

Qian Gang said, "I remember that he turned fourteen in May. Xu Hai is a celebrity in our area, notorious. Whoever God wants to destroy will be driven crazy, so it was inevitable that he would get into trouble. It's just that he didn't even turn fourteen and it turned out to be so tragic. I really didn't expect it."

Owen said: "Director Qian and Lao Du will take people to Xu Hai's home now to see what the situation is at home."
 
"I will go down the mountain immediately, call the people from the neighborhood committee, and go to his house." Qian Gang immediately left the hillside and went straight to Xu Hai's home with Du Feng's team.

Xiaolin walked around the banyan tree, looking for footprints under the tree and checking the trunk for signs of climbing. This big banyan tree is located deep in a path. The Municipal Park Management Office that manages the Elephant Hill has set up a small leisure area under the banyan tree, with a stone table disguised as a tree stump and four stone chairs.

Owen said: "Xiao Lin, be careful when you untie the rope. This kind of rope may contain the murderer's skin tissue."

"Well, it's difficult to extract skin tissue from this plastic rope. It mostly depends on luck." Kobayashi observed for a while and began to carefully remove the head.

Chen Yang said: "The body parts were cut so neatly along the joints, and even the intestines were neatly folded and packed in bags. What a deep hatred this must have. The murderer is most likely a family member of the victim that Xu Hai had violated."

Owen was completely in the case-solving mode, and all other distracting thoughts were completely buried deep in his mind. He said, "Except for the head hanging on the big banyan tree, the body parts found were all distributed on both sides of the main walking path up the mountain. That is to say, the murderer walked up the mountain along the main path and casually threw the body parts in the woods and grass on both sides of the path. He was very calm. The act of hanging the victim's head shows that the suspect did not want to hide the matter, but wanted to publicize it in a big way. The head was hung under this banyan tree, which also shows that the murderer knew this place."

He called Jiang Keyang to his side and said, "It seems that this case was a vent of anger by dismembering the body. There are many surveillance cameras installed on College Street. If the murderer wants to move the body parts here, he must have a means of transportation. Lao Ke, your team should check the surveillance points near College Street, make more copies, and try to extend the time as much as possible."

Jiang Keyang took Wu Qiang, Yuan Laian and Ma Xiaobing to retrieve the surveillance video.

A light breeze blew, and there was a faint smell of blood in the air. Chen Yang wrinkled his nose and said, "It's a pity that there is no surveillance on the Elephant Hill, otherwise it would be obvious. I will tell the municipal government to install surveillance inside the park as well."

More than 20 minutes after Qian Gang and Du Feng set out, Du Feng called back, his voice excited: "We found the murder scene, in Xu Hai's bedroom. When we arrived at Xu Hai's door, Xu Hai's grandparents were still asleep. We knocked hard on the door and they woke up. After waking up, they looked dazed. They must have been drugged. The murder scene was in Xu Hai's room. Xu Hai's bed was covered with blood. The suspect used four quilts to cover the bed. There was so much blood that all four quilts were soaked. There were three basins under the bed, and they were all full of blood."

Owen said: "Protect the scene and don't let Xu Hai's family enter Xu Hai's room."

Chen Ming, Lao Tan, Owen, Director Li of the Forensic Department and Director Xiao Lin of the Investigation Department went to Xu Hai's home together, while the rest of the staff continued to search the hillside.

When Chen Yang, Owen and others went down the mountain from the south slope entrance, a crowd had already gathered outside the cordon. A reporter from Jiangzhou Evening News appeared in the crowd, ready to interview Owen and others. After training at the Bayue Combat Training Base, Inspector Zhang Guoqiang and Owen had already reached a tacit understanding. After looking at each other, Zhang Guoqiang, Yan Feng and others used their bodies to block the reporters. Chen Yang, Owen and others quickly went down the mountain and headed straight for Xiangyang Community.

A large group of people gathered in the courtyard of Xiangyang Community, discussing the matter. When Owen bent down and prepared to get through the cordon, an elderly man asked, "Comrade, what happened to Xu Chongde's family?"

Owen stood still within the cordon and said, "I just arrived and don't know the situation yet. Is there a large floating population in your community? Is there any surveillance?"

The elderly man said: "We live in an old neighborhood, there is no gate, everyone can come and go as they please. The surveillance cameras are all on the street, not inside the courtyard."

"Why not contact the property management company?" Owen followed veteran investigators such as Zhu Lin on countless investigations and visits. He accumulated experience unknowingly and knew how to get the information he wanted most.

The old man rolled his eyes at Owen and said, "You are a well-fed man who doesn't know the hunger of a hungry man. This is an old neighborhood, and the residents are all poor. Every penny counts, and at least half of the people are reluctant to pay a few cents per square meter in property management fees. The street held several meetings and called a property management company for us. The property management company came, but couldn't collect the money. After working for less than two months, they clapped their hands and stopped caring about us. You are from the government, right? I'm telling you that for a neighborhood like ours, the government should pay for the property management company."

After a few words, Owen learned the basic situation of the community, which was exactly the same as what he had known before.

When entering the unit door, Owen received a call from Zhang Guoqiang.

Zhang Guoqiang said: "The team leader's judgment is correct. The murderer did dump the body along the main north-south road. After we set the search target near the main north-south passage, we found 18 plastic bags. The meat and bones in the bags weighed more than 130 kilograms. Due to the loss of blood and water, it is basically consistent with Xu Hai's weight."

Owen said: "Hurry up and send the body parts to the funeral home, and have them pieced together by the forensic department. Xu Hai's grandparents both took sleeping pills, and the body parts need to be tested by the physical and chemical laboratory."

As I entered Xu Hai's house, a strong smell of blood hit me in the face. It was much stronger than the smell of blood at Elephant Hill, making it hard to breathe.

An elderly man in his seventies sat on the sofa with a dazed look on his face.

Old Tan said: "Many people come here to play mahjong every day. There are a lot of footprints in the living room. There is no way to identify the suspect through footprints. Xu Hai's room has been cleaned and no valuable fingerprints or footprints were found. The doors and windows are intact and there are no signs of breaking the doors or windows. There are no signs of climbing near the window. The most likely possibility is that he entered through the main door."

Owen asked: "Is it someone I know who committed the crime?"

Old Tan said: "Judging from the traces at the scene, the suspect should be an acquaintance. Xu's house is a family mahjong room, and the latest mahjong was closed at 12 o'clock yesterday, which means the incident happened after 12 o'clock."

Chen Yang glanced at the old man in the living room and asked, "What's going on with them?"

Old Tan said: "The man is Xu Chongde and the woman is Duan Jiaxiu. They were probably given sleeping pills and are sleeping very soundly. They have no idea what happened last night."

The suspect gave the old man sleeping pills, killed and dismembered the man at home, cleaned the house and left, finally dumped the body at Xiangxiangpo and hung the head on a tree. The suspect's psychological quality was too good, so good that it was abnormal, which made Owen gasp.
 
Du Feng came out of the inner room and saw Owen. He said, "Yesterday afternoon, that is, the afternoon of March 28, there were three mahjong tables at Xu Hai's house, and four tables in the evening. There were 20 to 30 people playing mahjong at Xu Hai's house."

Owen asked: "Do Xu Chongde and Duan Jiaxiu usually take sleeping pills?"

Du Feng said: "I asked about this. They don't have the habit of taking medicine. After taking the sleeping pills, they slept very deeply and didn't hear any movement."

Old Tan said: "We are going to check the water cups of Xu Hai's grandparents, the purified water bucket, the water cup in Xu Hai's room, two beverage bottles, cigarettes, and biscuits to find out how the suspect put the sleeping pills in."

Owen asked: "Have you checked the knives in your home?"

Old Tan said, "There is no blood on the surface of the knife in Xu Hai's house. We are going to take it back for a closer look."

Xu Chongde heard the policemen whispering and came to his senses. He walked to Chen Yang like a sleepwalker and said, "You are an official, right? What happened to my grandson? Do you think he is not dead? Xiao Hai is dead, how can I explain to his parents? How could a living person be killed suddenly when he was at home? He was a good boy, often doing good things and being filial to his parents. You must solve the case, otherwise how can I explain it?"

Xu Hai is a devil in the eyes of everyone, but a good boy in the eyes of his grandfather. The contrast between the two is so great that Owen sighs inwardly.

Owen ignored Xu Chongde and went to Xu Hai's room, standing at the door to observe the situation inside. The room showed a very contradictory state. The bed and the ground were full of blood, and there was no dust on the table. The items were placed very neatly. Although there were many small sundries, they were in order. All the garbage was put into the trash can, and there was a plastic bag in the trash can, which was exactly the same as the garbage bag containing the body parts.

Du Feng pointed to the chair beside the bed and said, "Xu Hai's coat and underwear are all there, but his laptop is missing. On his underwear was Xu Hai's iPhone, which we temporarily confiscated and took back to check the last contact." There were clothes on the chair, folded quite neatly, with coats at the bottom and underwear at the top.

"Oh my Xiaohai! How am I going to explain this to your parents! I'm going to jump off the building soon. We'll die together. It will be cleaner if we die. Oh my Xiaohai!" Duan Jiaxiu had been lying in bed, her head dizzy. Before going to bed yesterday, she spoke a few words to Xiaohai through the door, and then fell asleep. She slept very well the whole night, but she didn't expect that when she woke up in the morning, something had happened to her grandson. She took a look at her grandson's room, stumbled back to her bedroom, and couldn't get up again. She was dizzy, and answered each question asked by the police. When the police left the room, she felt like she was in an endless nightmare. She didn't wake up from her self-paralysis until the phone rang. Seeing her son's number on the caller ID, she felt as if she had been electrocuted. She came out of the bedroom, came to the door of her grandson's room, sat on the ground, and cried.

Owen heard the earth-shattering cry coming from behind him, turned his head and took a look, and emphasized again: "Seal off Xu Hai's room, no one can enter or leave, and temporarily confiscate his computer, mobile phone, notebook, exercise book and other items."

He stood in the center of the house and observed its structure. It was an old-fashioned three-bedroom, one-living room house with a somewhat irregular structure that did not look square. The living room had been converted into a mahjong room with four mahjong tables. There were two bedrooms, one for Xu Hai's grandparents and the other for Xu Hai's room.

While observing the structure of the house, he turned on the high-definition camera mounted on his chest and recorded everything he saw.

The police dog training center brought in a bloodstain search dog named Binger.

Bloodstain search dogs use the specific smell of human blood as their target of sniffing, and can be used for on-site human bloodstain odor search operations without the need to set up a smell source on site. This technology is used in on-site investigations and investigative interviews of murders and other cases where bloodstains are left behind, and can quickly confirm whether human blood is left behind, and is closely integrated with DNA testing technology.

When Owen was studying at the University of Political Science and Law, he viewed police dogs as tools and did not truly view them as comrades. After close contact with Owen and Wangcai in the Criminal Police Building, he completely changed his mind and viewed police dogs as comrades from then on. The black bloodstain search dog could sense Owen's kindness and, in a rare move, wagged its tail at someone it met for the first time.

The police officer with the bloodstain search dog was a little surprised and said, "It seems that you are a dog lover. Binger is very smart and can distinguish between good and bad."

Owen said: "In the old Criminal Police Building, there were Owen and Wangcai. We had a pretty good relationship."

The policeman immediately realized who the young man in front of him was and said, "You are Owen. I have heard of your great name for a long time."

Owen did not take up the topic and said, "Generally speaking, finding the first scene is the key to the whole case. This case is different. The first scene and the scene where the body was dumped are very clear. Let's see if we can find the place where the murderer went after dumping the body through the possible traces of blood."

The police took Bingge out of Xu Hai's room and began to look for traces of blood.

The bloodstain search dog Binger lost its way soon after leaving Xu Hai's room. After arriving at the Elephant Hill, it shouted excitedly and went straight to the banyan tree. It accurately found the big banyan tree where the head was hung, and then found another discarded body bag. Unfortunately, the bloodstain search dog Binger was unable to find the suspect's whereabouts after he left.
