Because the victim's facial features were well preserved, the police quickly found out her identity. The victim's name is Jiang Lu, 24 years old, and she is a white-collar worker in an advertising agency.

It is understood that Jiang Lu's family conditions are very good, his father is a foreign company executive, his mother is a bank president, and he has been living a life of superior material conditions since he was a child, and has developed the habit of spending money lavishly. Although her parents have tried their best to control her expenses, she still can't quit spending money indiscriminately, often buying luxury goods, and especially showing off her wealth.

According to Jiang Lu's friends and colleagues, Jiang Lu is a severe "mobile phone dependent", and as long as she has a little free time in her life, she will feel uncomfortable if she doesn't brush Weibo and Moments.

Like many young girls, Jiang Lu also likes to post some private photos on the Internet, and the degree is much more serious than ordinary people, and she has no awareness of protecting personal privacy at all. The police looked through the photos uploaded by Jiang Lu in the last month and were surprised to find that the photos included almost all the details of her life. For example, when and where she bought beautiful bags, clothes and jewelry, which handsome guy went on a date with which high-end restaurant, what she ate, and what movie she watched, she had to send them all out, for fear that others would not know what she was doing.

The police speculated that the murderer should have found this eligible target from the Internet, easily obtained Jiang Lu's personal information, found her home address, and illegally infringed on her.

In order to get more clues, at 9 o'clock in the evening, the task force came to Jiang Lu's house. As soon as I opened the door, a familiar smell of blood hit my face.

Qi Ruonan was the first to walk into the scene with the survey box. As soon as she glanced at the situation in the living room, she sighed regretfully and said, "Alas, it seems that it is still very risky to show off your wealth online. The killer chose her as a target, not only because her facial features were up to standard, but also because she was eyeing her family's belongings. ”

Xiang Feng followed Qi Ruonan into the living room and teased her: "Don't you girls just like to post all kinds of photos on the Internet?" Something a little bigger has to be clockwork. The most unbearable thing is to take pictures before eating, and if you don't take good pictures, you don't let others move chopsticks, and having a meal with you can simply kill people. ”

"If you're troublesome, don't eat with girls! There are so many things, you deserve to be single. Qi Ruonan made a grimace at Xiang Feng, then looked back at Gu Song with a smile and asked, "Senior brother, you are so understanding, you shouldn't be troublesome for girls to eat and take pictures, right?" ”

"Oh......" Gu Song replied absentmindedly, but his attention was completely off the two bickering people. Seeing that Qi Ruonan was bored, Xiang Feng gloated and raised his eyebrows at her and said, "Our Detective Gu is busy with work, so he doesn't have time to take care of your little girl." ”

Qi Ruonan pouted, not caring about Gu Song's coldness in his heart, and continued to reason with Xiang Feng: "Is there anything wrong with sharing your life status with your family and friends appropriately?" As long as it's not as excessive as Jiang Lu. And when you send photos, you should also pay attention to the settings of personal privacy, and you can't let strangers view your photos casually. In today's society, there are too many perverted people, and at some point, the photos we post on the Internet will be used by others to do bad things. ”

"Jiang Lu is a living example." Xiang Feng said as he took out the tools from the survey box. "I've seen the photos she posted on the Internet, and it's a bit ostentatious. Even if nothing happens this time, sooner or later it will be remembered by the thieves outside. ”

"Therefore, girls must learn to protect themselves. Especially for women who live alone, you must not open the door to a strange man. After Qi Ruonan finished speaking, he also opened his survey box and prepared to start work. At this time, Gu Song suddenly called her at the door of the bathroom, "Xiao Nan, come over for a moment." ”

Qi Ruonan immediately walked over when he heard the sound, stood at the door and observed the situation inside.

The bathroom is about seven or eight square meters, with a coffee-colored marble sink with a pattern on the right hand side of the door, a fully automatic toilet on the left hand side, and a rectangular jacuzzi directly opposite. Judging by the dark red blood stains that dried up on the ground and walls, this should be the scene of the first murder of the murderer.

Qi Ruonan first took a few photos with a DSLR camera, and then walked inside to check them carefully. "This kitchen knife is the tool used by the murderer to shred the corpse, right?" Qi Ruonan picked up a bloody knife from the ground, turned it over and looked at it, and said, "This is the German Zwilling brand, one of the best knife brands in the world." The blade of this knife is very sharp, and cutting vegetables is not a task at all, but it still takes some effort to chop up corpses. ”

"I remember that in the six cases of corpse mutilation a few years ago, Wei Chiliang lured the victims to his villa to commit the crimes. There is a basement in the villa that is dedicated to killing, and it is equipped with all the tools in it, and it feels like those scenes from the American drama "Criminal Minds". ”

"Time has passed, and Wei Chiliang no longer has his own 'independent studio', so he can only simplify the means of committing the crime and use local materials. This knife must be something from the victim's house, and it is estimated that no clues can be found from it. ”

"It's not much hope." Gu Song frowned, what he was thinking about was not to find out more clues from the murder weapon, but to change the murderer's modus operandi again. However, perhaps, as Qi Ruonan said, the reality no longer allows Wei Chiliang to kill people as recklessly as before, and his modus operandi can only be forced to change. But why burglary again? When did Yu Chiliang change from a perverted murderer to a burglar? Is he really so short of money now?

After thinking for a moment, he said to Qi Ruonan: "No matter what, let's put the knife away first." The murderer disposed of the body here, and the stay was certainly not short. You are delicate, look for it again, and see if he has left any clues. ”

"Leave it to me." Qi Ruonan replied confidently, and as soon as she finished saying this, she sighed depressedly, "However, we now know the identity of the murderer, even if we find something, it can only prove that he killed another person, and it can't help us find his whereabouts!" ”

Gu Song shook his head and said, "Don't make a conclusion about this matter too early. I think there are still some strange things about this case, and we must not let our guard down. ”

"Strange? What's wrong? Wei Chiliang has already made his purpose very obvious, he is blatantly provoking the police and insulting the dignity of our police in R City. ”

Two hours later, Qi Ruonan and Xiang Feng carefully inspected the entire house, inside and out, and the result, like the previous two cases, did not find any valuable fingerprints and footprints.

It is estimated that the victim's lost cash, watches and jewelry may be worth more than one million yuan, ranging from items purchased by the victim with her parents' money to gifts from her former boyfriend.

In addition, according to the photos posted by the victim during his trip abroad during the New Year's Day, a stone brown RIMOWA suitcase was missing from the victim's home, and it was presumed that the murderer had taken it to transport the body. The police have sent people to search the suitcase throughout the city, hoping to get some valuable information from the suitcase.

After the technical department finished investigating the first crime scene, the autopsy report from Forensic Doctor Chen also came out.

Based on the analysis of the corpse, stomach contents, and investigators' investigation information, the victim's time of death was around 10 p.m. yesterday. The cause of death was a sharp cut in the neck, resulting in a ruptured carotid artery and blood loss, and the tool of the crime was the Zwilling kitchen knife that Qi Ruonan brought back from the victim's home.

Although the murderer's methods of killing and dismembering bodies have changed somewhat compared with the serial homicide case a few years ago, the police do not believe that this case was imitated by others because the killer followed the unique criteria of selecting the victim and left a provocative note at the scene of the dumping of the body. Counting the "Lanting Villa Murder Case" and the "Guanghua Community Double Corpse Case", this is the third case committed by Wei Chiliang when he returned to R City. Combined with the six cases between 2012 and 2013, the number of lives tragically killed at the hands of Wei Chiliang has reached ten.

According to the victim's best friend, the two had dinner together last night and were separated in the underground garage of the mall at around 9:10. According to the community surveillance video, the time when the victim entered the underground garage was 9:37, that is, at about this point in time, the victim was unfortunately attacked by the murderer.

The victim's best friend also said that although Jiang Lu has a flamboyant personality, she is not a girl who is completely unvigilant. At around 10 o'clock in the evening, Jiang Lu would not open the door to a man she didn't know, because she herself knew that there were a lot of valuable things at home. However, since the murderer is a scheming person, he must have a way to trick Jiang Lu into opening the door for him. Or, he could also ambush Jiang Lu's house in advance, and forcibly enter the house while she opened the door with the key to go home, such a case has not happened before, not to mention that the murderer still committed the crime with a gun.

Community surveillance footage shows that at 10:42 p.m. last night, a man wearing a dark blue windbreaker dragged a stone brown suitcase out of the gate of the community.

Judging from the video, the man was wearing a beanie, sunglasses and a mask, covering all his facial features, and he couldn't see what he looked like at all. But judging from the figure, this person is more similar to the man who stole the access card near the Lanting community. At that time, Qiao Sheng went to the community to find out about the situation of the aunt who lost the card, and learned that the person who stole the things was also wearing a dark blue trench coat.

After leaving the gate of the community, the man dragged his suitcase all the way to the north, and disappeared when he came to a small road without surveillance.

The victim's neighborhood was about seven kilometers away from the place where the body was dumped, and the killer was dragging a heavy suitcase, which was impossible to reach on foot, and must have taken some kind of transportation that night. At present, the police are collecting a large number of road surveillance to track down the whereabouts of the suspicious man.
