The news of the murder of Yu Chilong, a wealthy man in R City, quickly spread on the Internet, and the related reports that followed also made the front page headlines of major media websites.

For a time, the police in R City were pushed to the forefront of public opinion. While people are asking the police to find out the truth and catch the murderer as soon as possible, another fatal question raised by this case has also been put on the table: where did the serial killer Chi Liang go? He killed six people with brutal means, and the police allowed him to run away from society for two years, when will he be arrested?

Seeing comments like this, the leaders of the R City Public Security Bureau were all under tremendous psychological pressure. In fact, they were afraid to hear the name Wei Chiliang, because this person had already humiliated the police in R City too many times. They also don't want to let a demon continue to wander outside and continue to do things that harm society and the interests of the people. But how easy is it to say that he was captured in the middle of nowhere?

For more than two years, they have never given up the pursuit of Wei Chiliang. But if a clever and cunning criminal like him really wants to hide it from the police, they may really have nothing to do with this person.

However, they must put Yu Chilong's case first now. As for tracking down Wei Chiliang's whereabouts, they announced to the outside world that they would intensify the search, but in fact they could only do it step by step.

Regarding this matter, Qiao Sheng's personal opinion is that the murder case in Lanting Villa and the whereabouts of the serial killer are two different things on the surface, but there is a subtle connection between them.

Nowadays, the Internet is so developed and the speed of information transmission is so fast, no matter where Wei Chiliang escapes, as long as he is still in the modern human society, he should know the news that Yu Chilong was killed through some channels.

As the son of Yu Chilong, Yu Chiliang may be attracted by this sensational news, secretly return to R City, and may even approach the scene of the crime. For the police, this may also be an excellent time to capture Wei Chiliang.

On the afternoon of January 14, 2016, the R City Criminal Police Detachment made a comprehensive summary of the information it had learned about the "Lanting Villa Murder Case".

Through further autopsies, the medical examiner pinpointed the victim's time of death between 7 p.m. and 10 p.m. on January 9, 2016. The victim had obvious restraint injuries on his wrists and ankles, as well as multiple coercion injuries on his body, all of which were detected as life reactions, which were injuries before death. The victim was stabbed thirteen times in the chest and abdomen with a single-edged knife about 3 centimeters wide, two of which were fatally stabbed in the heart of the victim.

Referring to the time of the victim's death, the police conducted a detailed investigation of the entrance registration information of the Lanting community and the monitoring information at the entrance, inside and around the community.

Lanting Community is a high-end community in R City, where many rich people live in it, and the security work is very good. People must swipe their cards when entering the entrance of the community, and visiting relatives and friends and other door-to-door service staff must register their personal information at the entrance of the community before they are allowed to enter (including the registration of vehicles entering the door). If the suspect's family does not live in this community, then theoretically speaking, he must register at the entrance when he enters the Lanting community.

The police recorded all the people who had registered from the morning until 7 p.m. on January 9. Of the 109 people, 57 people remained, excluding children and women (considering the murderer's ability to subdue and injure, it is very unlikely that the murderer was a woman). Among them, there were 21 people who visited relatives and friends, and after verification by the police, all of these people's circumstances were true, and none of them were suspected of committing crimes.

In addition, there are a total of 36 other door-to-door service personnel, such as tutors, hourly workers, maintenance workers, and delivery workers, whose door-to-door service information has also been verified by the owners. Combined with the information provided by the community's surveillance footage, only 5 of the 36 people left the community after 7 p.m. The police need to do further research on the stay of these five people in the community and their identity information.

Because the victim had no close relatives around, the police were unable to accurately verify the missing belongings in his home. However, according to information obtained from the bank, Wei Chilong had purchased 12 500-gram gold bars from the bank in the first half of 2015. The police speculated that the gold bars should have been hidden in the safe in the study, and the murderer forced Yu Chilong to open the safe and take the gold bars away.

In addition, what the police learned from Shen Li, a part-time worker, was that the victim often wore a Rolex watch worth about 200,000 yuan before his death, but this watch disappeared from the scene of the crime and was suspected to have been taken by the murderer.

Yu Chilong was originally the owner of Xinlong Real Estate Development Company, and his business was booming, and he had a place on the rich list of R City for a long time. But after his son Yu Chiliang became a serial murderer and was wanted by the police, Yu Chilong was deeply shocked and his life changed dramatically.

As the father of a serial murderer, Yu Chilong inevitably suffered strong criticism from public opinion and lost face. The incident seriously affected his business. It didn't last long, he couldn't stand the pressure, sold the company at a low price, and since then he has avoided people's attention and lived a reclusive life.

In the two years from the beginning of 2014 to the time before he was killed, Yu Chilong had almost all contact with the outside world, and even relatives and friends did not have much contact. Except for walking the dog and buying groceries, he rarely goes out and doesn't talk much to the neighbors around him. He was afraid of being disturbed by the outside world again, afraid of hearing people slander him with vicious language, and even curse him to death.

Perhaps in order to atone for his son's sins, Yu Chilong began to eat fasting and chant Buddha in 2014, dedicated to goodness, and completely abandoned the luxurious and hedonistic life of the past.

Due to the failure of the business and the serious shrinkage of assets, Yu Chilong's second wife left him two years ago and got along with another man. The man who was once so glamorous has fallen to this point because of the mistakes made by his son, which is indeed sympathetic to think about it.

Although the state presented at the scene of the crime is a typical burglary and homicide, considering that the victim has been in the business for decades and has complicated interpersonal relationships, the possibility of an acquaintance committing the crime cannot be completely ruled out at present.

In addition, the killer's excessive injurious behavior and the way he treated the Labrador Retriever indicated to a certain extent that the killer may have been an acquaintance of Yu Chilong.

According to the information obtained by the Criminal Technology Division, the murderer did not break the door lock when he entered the villa, and there were no signs of climbing on all the windows, which means that the murderer entered the villa from the main entrance openly. If the killer doesn't have the key, then the victim must have opened the door for the killer himself. If the murderer is an acquaintance of the victim, the problem is well explained. Otherwise, at least at the first glance of Yu Chilong, the murderer's dress and appearance did not make him vigilant.

Combined with the autopsy report of the medical examiner, no resistance injuries were found on the victim's body. So how did the killer quickly subdue the victim, tie them up, and make them resist? The answer is most likely that the murderer had a gun.

The killer did not leave any valuable fingerprints and footprints at the scene of the crime. His purpose was clear, his modus operandi was clean, he quickly subdued the victim and went straight to his family's belongings. Aside from the puzzling fact that he locked the victim's dog in an underground warehouse and prepared plenty of water and food for it, all other aspects show that the killer was a cunning and vicious person with a lot of experience in committing crimes.

In the next two days, the police began to methodically check the victim's social connections, and once again checked the identity information of the community registration personnel on the day of the crime, and also kept a close eye on the movement of the stolen property. In addition, Qiao Sheng also sent several groups of people to closely monitor the surrounding situation of the Lanting community.

At noon on January 16, 2016, investigators Fan Cong and Zhao Xiaolin were sitting in the car in a bored daze. The two of them had just finished lunch, and in the warm sunshine, they couldn't help but feel sleepy. The replacement workers still had three hours to come, but they had already entered the state of leaving work early.

Although Lanting Community is located in the suburbs of the city, far from the city center, the urban supporting facilities in this area are very well built, and there are several other high-end communities with good quality around it, which are very popular.

During the lunch break, vehicles and pedestrians pass by from time to time around the neighborhood, and the restaurants on the street are doing brisk business, presenting a peaceful and peaceful scene in front of you, as if the murder of a few days ago had never happened here.

Fan Cong's car was parked on the side of the road diagonally opposite the main entrance of the community, and near the other secondary entrance, Qiao Sheng also arranged for other colleagues to squat. They had only one purpose, that is, to find out the person suspected of being Wei Chiliang in the passing crowd.

In fact, the eyesight of a few of them alone is definitely not reassuring. Qiao Sheng also sent people to keep an eye on the surveillance video around the community 24 hours a day. Once the target is spotted, the surveillance team that has been squatting in the vicinity of the community in advance can move quickly.

"Huh? Xiaolin, look at that person! Fan Cong suddenly pushed his sleepy partner and pointed in a direction. The latter yawned, straightened up, and looked across the road. His eyes were not as sharp as Fan Cong's, and he observed intently for a few seconds, and asked quite puzzledly, "Who are you talking about?" ”

"Oops, you look through a binocular. At two o'clock, about 80 meters away from us. Dark blue jeans, black sweatshirt, the one with a hat. ”

"Oh, I saw it." Zhao Xiaolin asked while observing, "Is there anything wrong with that person?" ”

"Don't you think he's a bit like ......"

"Wei Chiliang?" Zhao Xiaolin asked suspiciously. "The face is a little blocked, and I can't see clearly. In this way, I contacted my colleagues in the monitoring team and asked them to confirm it through the video. If that person is really Wei Chiliang, we will ......" Before Zhao Xiaolin finished speaking, Fan Cong had already taken out his mobile phone and dialed a person's number.

"Hey, Team Qiao, we found a suspicious figure near the main entrance of the Lanting community."

"Brother Cong, what are you doing?" Zhao Xiaolin looked at him in surprise, "We haven't confirmed the identity of that person yet, why did you report the situation to the captain so quickly?" Fan Cong glanced at him, ignored him, and only heard Qiao Sheng ask emotionally on the other side of the phone, "Did you find Wei Chiliang?" ”

"Well, sort of. But ......"

"What's wrong? What's the situation? ”

Fan Cong paused slightly, his expression suddenly became very serious, and even Zhao Xiaolin, who was sitting in the co-pilot, couldn't help but become nervous.

"Why don't you speak?" Qiao Sheng urged anxiously.

Fan Cong took a deep breath and replied slowly: "That person looks a bit like Wei Chiliang, but I think he is more like Gu Li......"
