Chapter 5 Chapter Four

Since the incident occurred last night, that is, December 6th, the case was named the 126 Extraordinary Murder Case.But at this time, Gao Dong obviously did not expect that this case would be renamed the 126 Extraordinary Serial Murder Case in a short time. In the evening, Gao Dong had just received the preliminary autopsy report from the forensic laboratory, and immediately called a meeting of the members of the task force. In addition to the leaders of the county bureau and the entire criminal investigation team, the other dozen or so people who attended the meeting were all brought over by him from the city bureau, because the police in small county towns can pass ordinary criminal cases and have little experience in major cases. And he also believed in the ability of the people he brought.

The local people are mainly responsible for investigating, visiting and collecting information. Gao Dong turned on the projector and said, "I won't say much about the importance of this case. It is said that the provincial department will report to the ministry soon. We must hurry up and find the murderer as quickly as possible. Some comrades are like me, from the city bureau. , I couldn’t get to the scene in the first time in the morning, let’s take a look at the general situation of the case first.” He pressed the remote control of the projector, switched the screen, and continued: "This is the photo of the deceased Li Aiguo when he was found."

In the picture, Li Aiguo, who is in his forties, tilted his head and opened his eyes, lying on the driver's seat with no expression on his face. There was a large amount of dark red blood on his chest and heart, which flowed down to the driver's seat. "There was only one obvious trauma on Li Aiguo's body, and the wound was right in the heart. According to the forensic doctor's guess, the murderer probably stabbed Li Aiguo's chest with something like a three-edged spear, and it was right on the heart. Li Aiguo probably did not exceed half of the wound. Dead in minutes."

"Let's take a look at the other photos. The interior of the car is clean and there are no traces of fighting." Speaking of this, many people have discussed how they killed people without fighting. Gao Dong coughed, indicating to discuss later, and continued: "In the drawer of the passenger seat, there are 20,000 yuan in cash, and there are some high-end cigarettes and alcohol in the trunk. The murderer has not touched it after the murder. Obviously, the murderer Killing is not for money." He switched to another picture, which was the front view of the car. On the windshield in front of the car, there was a banner with white cloth and red letters on it, which read, "Kill enough for the chief, fifteen, but not enough for the chief."

He did not comment on this picture, and continued to change photos from various angles of the car. After finishing, he said: "The deceased, Li Aiguo, was drinking and playing cards with some friends in the hotel last night. According to his friend's confession, they met at about half past ten Afterwards, Li Aiguo drove away alone. According to the monitoring at the intersection of Haiyan South Road and Fengqi Road, Li Aiguo's car entered Fengqi Road at 10:52, but the camera at the entrance of the community did not capture the Audi car entering the community. It shows that Li Aiguo was killed in front of the community after driving into Fengqi Road, and the specific time of his death should be around 10:55. The result of the forensic examination of the death is also consistent with it."

"Li Aiguo's wife confessed that Li Aiguo called her at about 9 o'clock last night, saying that she would be back late after playing cards at night. Li Aiguo's wife didn't feel anything unusual, so she went to bed first. She didn't know what happened until this morning. I went to check in the afternoon. According to his call records, he did make a phone call with his wife around 9 o'clock last night." "At present, there are several difficulties in this case. After the murder, the murderer wiped the fingerprints on the inside and outside of the car with a cloth. Since Li Aiguo had never fought with the murderer, Li Aiguo's nails, body and inside the car were not found. The murderer's hair, dander, fiber and other objects. The footprints on the cement floor outside the car were deliberately destroyed by the murderer. The murderer left footprints on the floor mat inside the car, but the floor mat was taken away by the murderer. After the murder, the murderer , fled to the ditch along the farmland next to it, and where it came up from, it is temporarily impossible to find out. According to the forensic description, the murderer probably had a flat-bottomed iron shoe cover on his feet at that time, so a string of flat-bottomed 47 Large footprints. The flat-bottomed iron shoe covers make the pressure of the murderer's body weight on the ground even, so it can only be inferred that the murderer's weight is between 120 and 140 catties, and his height cannot be judged. That is to say, until now So far, the murderer has not left any physical evidence."

"Are there any witnesses?" a policeman asked. Gao Dong shook his head and said, "The incident happened near late at night. There were few people on this Fengqi road, but now it's winter, so there are even fewer people walking on it. According to the security guard in Fengqi community, he was sleeping in the security room at the time and didn't listen. There is unusual movement outside." Director Guo Hongen said: "That is to say, up to now, the murderer has not left any personal or physical evidence during the entire killing process?" Gao Dong nodded: "Exactly."

The meeting room was full of sighs, and everyone was whispering and discussing how to solve the case without evidence. Gao Dong glanced at everyone, coughed, and the discussion stopped. He continued: "According to his friend's description, Li Aiguo drove home last night alone, and the surveillance cameras also showed that there was no one in the passenger seat. , but at the time of the incident, the murderer was obviously in the passenger seat. So we can restore the whole incident. Li Aiguo drove home alone after the show ended at 10:30 last night. After entering Fengqi Road, I don’t know For some reason, it stopped halfway before reaching the gate of the community, and opened the safety lock inside the car, opened the door to let the murderer get in the car, the murderer sat in the passenger seat, and then killed him."

Captain Chen of the county team said: "How did the murderer kill Ju Li? Even if the murderer had a three-edged spear, but the space inside the car is small, how could he stab the stab into Ju Li's body without a fight? It is right in the heart, and the position is unbiased, but there are no wounds in other parts of the body." Gao Dong said: "The answer can only be that before the murderer stabbed the spear into Li Aiguo's heart, Li Aiguo had already stopped moving and completely lost the ability to resist. Because if Li Aiguo could move, the murderer would have no choice but to stab it just right. The location of the heart was cut, and no wounds were left on other parts of the body. Even if the murderer was really lucky, Li Aiguo still had the ability to resist within a few tens of seconds after being stabbed. It is impossible that there were no signs of a fight. I will go to see the After passing Li Aiguo's body, I found that Li Aiguo's neck below the root of the ear had a small burn mark. I discussed it with Chen Forensic Doctor. It should be that the murderer took a high-voltage electric shock rod and stunned Li Aiguo with the electric shock rod first. , aim at the heart, and stab it with a gun. Of course, it has been more than half a day since his death this afternoon, so the forensic doctor can’t use body fluids to identify whether Li Aiguo received an electric shock before his death. This is our inference and the most reliable possible inferences."

The meeting room was full of sighs, because in this ordinary county town, no one had ever encountered a murderer. First, he was stunned with an electric shock baton, and then directly stabbed into a deadly organ. Ordinary criminal homicides are mostly accidental homicides, even premeditated revenge homicides, the means are very crude, often with axes, hammers, sharp knives and other weapons. Using an electric shock baton to stun first, and then inflict fatal injuries that can cause instant death is a very straightforward method, and it leaves the least traces of the crime. Gao Dong said: "The basic case has been introduced here. There is no physical evidence for the time being, and we don't know anything about the murderer's age, gender, and physical characteristics. Everyone can put forward any opinions on this case and brainstorm."

Zhang Yiang, Gao Dong's key staff member, said: "After the murder, the murderer didn't take any money or property, which means it was a vendetta. I think we can start from the perspective of the deceased's social relationship." The discussion started again, and there were many discussions about who had hatred against the deputy director of the Public Security Bureau. When it comes to talking about it, there are many people who have hatred against Li Aiguo, but it seems that the hatred that would kill people to vent their anger can't be imagined at once.Besides, even if there is a grudge, how many people have the courage to kill the deputy director of the Public Security Bureau. This is obviously a major case that must be solved, and the death penalty is the death penalty. Another old criminal policeman had a different opinion: "In my opinion, the murderer left the words on the windshield. It doesn't necessarily mean that the murderer had a grudge against the deceased. It may be someone who hates society and takes revenge on civil servants." Gao Dong interjected: "It's enough to kill the chief of the fifteenth, but the chief is not enough to make up for the section chief." When he said this again, even though the conference room was full of experienced old policemen, he still felt a chilling haze. .He snorted coldly and said, "The murderer spoke very loudly. This incident shocked the leaders at the provincial and municipal levels. The leaders were worried that they would continue to commit crimes according to the murderer's tone. I don't care if the murderer hates society or not. He's under arrest!" These words were resounding, and everyone knew that when this case came out, everyone was under heavy pressure. In fact, it was not Gao Dong who was under the most pressure on the scene, but Guo Hongen, the director of the bureau. Because according to the practice of the public security system, murder cases must be solved.If there is a murder case that is not solved, the person in charge is likely to be transferred.Even if the relationship with the person in charge is strong, it will be troublesome to get promoted in the next few years, and competitors will always bring this matter up. So now in many places, when there are criminal cases, especially homicide cases, they often try their best not to file the case, so there are a lot of news about "suicide". One of the important reasons for this is that "homicide cases must be solved" in the public security evaluation system.Therefore, the detection rate of homicide cases in our country is as high as 90%. ——Because many places practice "nothing can be broken, nothing can be built". And this time, it was a huge murder case, and it would definitely be solved.If the case cannot be solved in the end, even though Gao Dong is the supervisor, he can also excuse it as co-organizer. After all, Baixiang County has nothing to do with him.But Director Guo Hongen, as the person in charge of the jurisdiction, couldn't escape at all.He was originally sent to the department to train and accumulate qualifications. He had no experience in solving major criminal cases before, so now he can only pin his hopes on Gao Dong. Gao Dong glanced at everyone, softened his tone, and comforted: "Everyone don't need to be nervous, we are just beginning to analyze the case now, don't put pressure on yourself, let's continue talking. I think it is possible to say that the murderer is for revenge on the society , the murderer has a personal enmity with Li Aiguo, or it is possible that the writing is to divert our attention and make our investigation angle turn to those elements who hate society. These two possibilities cannot be determined for the time being." Zhang Yiang said: "I think the biggest doubt now is that when Li Aiguo's car drove to Fengqi Road, it was almost in front of the house, why did it stop, and let the murderer get in the car again, and he was not wary of the murderer's actions." Gao Dong nodded and said, "That's right, this is the focus of attention. According to our driving habits, if we drive on a road with little traffic in the middle of the night, what circumstances will prompt people to stop halfway?" One person said: "Go to the toilet by the side of the road?" Immediately, someone retorted: "We are almost home, how could it be possible that we can't hold back for a minute or two?" Gao Dong said: "What's even weirder is that Li Aiguo actually let the murderer get into the car. When you drive on the road in the middle of the night, under what circumstances would you allow people outside the car to get into the car?" Zhang Yiang said: "The murderer is an acquaintance of Li Aiguo?" Gao Dong said: "I can't be 100% sure, but the possibility is relatively high." Director Guo Hongen said: "It seems that we still need to investigate Li Aiguo's social relations carefully." Gao Dong said: "This is one piece of work. Another piece of work. Judging from the murder carefully prepared by the murderer, the murderer stayed on the road ahead of time to watch Li Aiguo go home. Judging from the circumstances of the crime scene, there is only one murderer. The problem now is Yes, how did the murderer know that Li Aiguo would come home late last night? There are three possibilities. In the first case, some of the friends who played cards with Li Aiguo last night were accomplices. In the second case, the murderer has accomplices who are following Li Aiguo , while the murderer was in ambush on Fengqi Road in advance. In the third case, the murderer had been following Li Aiguo for many days to kill Li Aiguo, and he knew Li Aiguo's behavior and habits very well. He had followed Li Aiguo in advance yesterday and knew that he was playing cards in a hotel. It may be quite late, so I ambushed on Fengqi Road in advance. Now we need to determine whether the murderer's entire murder operation was completely organized by him alone, or whether there were other accomplices." Team Chen asked, "How to check this?" Gao Dong said: "No matter what the situation is, the murderer must have been followed and checked many times before the crime happened. There are so many surveillance cameras on the roads in the county, and there will definitely be traces." Guo Hongen said: "I'll arrange people to investigate immediately." Gao Dong said: "This job is a lot of work, let's put it aside for now, we have more important things these days. Team Chen, in the afternoon, I will ask you and the traffic police to get the surveillance cameras on Haiyan South Road and Haiyan North Road. Reached?" "Well, got it, they only keep fifteen days of footage." "Fifteen days, that's enough. What about the monitoring at the gate of the community?" "Take it too, they only keep it for ten days." "Ten days is about the same. By the way, how is the quality of these three monitoring?" "They are all high-definition cameras used on high-speed roads. Because it is a civil servant community, and some leaders of the traffic control department live in it, so when it was first built, the living safety of its surroundings was considered, so the three cameras were all high-definition cameras, which are better than those in the urban area. The surveillance in other places is fine." Gao Dong nodded in satisfaction: "Then how is the light on Fengqi Road at night?" "Very ideal, less than 20 meters on both sides, there is a street lamp on each side, and the lighting brightness is much better than other road sections." The surrounding supporting facilities of the civil servant community are really good. Gao Dong continued: "That is to say, these three surveillance cameras can clearly capture pictures at night?" "Well, the surveillance video is very clear, but..." Team Chen worried, "But the surveillance cannot capture the crime scene." Gao Dong said: "Before the murderer commits the crime, he will definitely go through surveillance." "If the murderer also came from the ditch before committing the crime, wouldn't the surveillance be able to capture it?" Gao Dong said affirmatively: "This is impossible. First, the murderer had already been guarding Fengqi Road before committing the crime. It was too early before committing the crime. If the murderer came from the ditch, it would easily attract the attention of passers-by. Second, the water in the ditch is knee-deep. If the murderer's pants are wet, the dead will be alerted. Of course, you may say that the murderer's pants are wet and he hid in a corner to dry them, but it's too much trouble to do so. Yes, there are great hidden dangers, and it does not conform to the murderer's clean and neat modus operandi." Gao Dong said: "Have you noticed the terrain where the crime happened? The crime happened in the southern section of Fengqi Road running north-south. At the intersection of the southernmost end of Fengqi Road and Haiyan South Road, there is a surveillance probe. In the middle of Fengqi Road , which is the main entrance of the community, there is a probe. There is also a surveillance probe at the intersection of the northern end and Haiyan North Road. Although there is no probe at the crime site, the entire Fengqi Road is monitored at both ends and in the middle, and the community is on one side. The high wall is too high for the murderer to climb, and there is barren fields on one side, the murderer will not go through the barren fields when he comes. That is to say, the entire Fengqi Road is a completely closed area." Gao Dong glanced at everyone and found that everyone hadn't followed his train of thought. He emphasized his tone: "The murderer must have entered Fengqi Road before committing a crime. There are surveillance cameras at both ends and in the middle of Fengqi Road, so the murderer must have entered Fengqi Road." It will definitely be recorded by the surveillance probe. Team Chen and my people will focus on the investigation together. After 6:00 last night, every person and every car entered Fengqi Road and did not leave the next probe, or the vehicle got off halfway. People, it means that this person is stranded on Fengqi Road, then he is the murderer!" As soon as these words came out, the meeting room was instantly excited. Gao Dong was indeed an experienced criminal investigation expert, and he quickly found out the direction of a death case that had no witnesses at all. Every vehicle and person that entered Fengqi Road that night, as long as they entered Fengqi Road through one probe, and did not leave Fengqi Road through any probe within a short period of time, it means that the person stayed on Fengqi Road. Obviously, if this person stayed on the road, he must be the murderer. Once this line of thinking is clarified, the future work will have a direction. Fengqi Road is not a major road, and the number of people traveling by car is limited, so the investigation should not be too difficult. Just when everyone was full of confidence that they had a direction, Gao Dong received a call. After the call, he was silent for a moment, and finally said: "Li Aiguo lost the June 4th gun on his body, and the holster is in the car drawer. There were five or six rounds, which were also taken away." Guo Hongen pursed his lips and did not speak.After all, he is a leader-level figure and cannot let others notice his anxiety. Everyone was silent. Gao Dong coughed lightly, and said, "The murderer has a gun in his hand, so he must be arrested as soon as possible. Now there are five aspects of work to be done. First, Team Chen, you are in charge of making arrangements. Immediately do what I said to check Fengqi Road." Three monitoring, this is the most important job at this stage. In the past few days, everyone will stay in the bureau and take turns working overtime, and work hard. Second, Guo Bureau, I need you to arrange some people here, check the road monitoring in the whole county, and see Some time before the incident, was there any suspicious vehicle following Li Aiguo's car? Third, Zhang Yiang, please contact the evidence experts of the Provincial Public Security Bureau to re-identify all the remains at the crime scene to see if you can find Find out some clues. Fourth, Team Chen, you should arrange someone to be responsible for recording detailed statements for Li Aiguo's friends last night, as well as his relatives and friends, listing the complete social relationship, and investigating his social relationship. Is there any abnormal behavior? Fifth, Bureau Guo, I still want to trouble you. There are not enough manpower now. We need to call in some experienced police officers from the lower-level police stations in various jurisdictions, and carefully visit the surrounding area to see if anyone saw him that night. People who have experienced abnormalities. Alright, let’s start from the aspects of monitoring, physical evidence, witnesses, and social relations, mobilize the entire police, go all out, and solve the case as soon as possible!”
