Because of the relationship between the serial murders of female artists, Jun Youyao began to follow Chi Yuling in the police station all day and night, either in front of the autopsy table or in the laboratory.

It really allowed them to find some useful clues on the corpse.

All three deceased individuals had benzene residues in their fats that were far higher than normal.

"What does that mean?" Liao Yanbo obviously didn't quite understand what these values mean.

Jun Youyao replied: "It shows that there is a high probability that the victims have been locked up in an environment where the TVOC exceeds the standard." ”

He didn't wait for him to continue to ask her what TVOC was, and explained directly: "TVOC refers to organic matter with a saturated vapor pressure of more than 133.32Pa at room temperature, its boiling point is between 50C and 250C, and it can be evaporated in the form of air at room temperature, its toxicity, irritation, carcinogenicity and special odor will affect the skin and mucous membranes, and cause acute damage to the human body, mainly classified as benzene, alkanes, aromatic hydrocarbons and so on. ”

"Generally speaking, the main sources of TVOC are outdoors, fuel combustion and transportation, while indoors they come from combustion products such as coal gas and natural gas, smoke from smoking, heating, as well as adhesives, coatings, paints and so on in buildings and decorative materials, including furniture, home appliances, cleaning agents, and even emissions from the human body itself."

She said and handed him a test sheet, "Due to the surprise of physiological structure, TVOC has a greater impact on the female body, and the fat component in the female body is larger, and harmful substances will be stored in the fat after absorption." The benzene content in the fat of the three victims exceeded the normal value, and then I examined their throats and eyes one after another, and each of them had a certain degree of dry throat and dry eyes, and their liver and hematopoietic system were damaged to a certain extent, and they had allergic reactions, which were all symptoms of being harmed by TVOC. ”

Jun Youyao didn't say it too difficult, Liao Boyan nodded and asked, "Miss Jun, what do you think this question illustrates?" ”

Although they had only worked together for two days, Liao Boyan could see that this young girl was very sensitive, so he couldn't help but want to refer to her opinion.

"I made a comparison chart based on the data of the victims' physical aging." Jun Youyao took out a drawing from his briefcase, on which a number of curves were marked in red, blue, and black.

"The red line represents the average aging process of the three of them in five days, the three black lines represent the benzene content of the human body with normal metabolism at 2.5 mg/m3, 5 mg/m3 and 10 mg/m3 at the same time, and the three blue lines are the benzene content values at 2.5 mg/m3, 5 mg/m3 and 10 mg/m3 at the normal metabolism of the victims, respectively, according to the metabolism rate of the victims." ”

Finally, she pointed to one of the blue lines and said, "The last one is the closest to the amount of benzene in the victim's body." ”

"TVOC concentration 10mg/m3?" Liao looked at the value marked at the left end of the blue line.

Jun Youyao nodded: "Given that our murderer is not a stupid person and has no habit of killing people outdoors, then we can infer a point from this value, the murderer may have recently renovated the house within three months, and was miserable by the decoration company, and they used decoration materials that did not meet international standards." ”

Indoor TVOC concentrations are usually between 0.2 mg/m3 and 2 mg/m3, and in improper decoration construction, it may be dozens of times higher. Due to the strong volatility of TVOC, under normal circumstances, 90% of the paint can be volatilized within 10 hours after application.

Liao Boyan's eyes lit up when he heard this, and he snapped his fingers with the report, "We can check all the decoration companies in the imperial capital, especially those with non-standard construction, and see who they have helped with decoration in the past three months?" ”

"It's also a good idea to check paint suppliers and adhesive suppliers by the way, some people choose to source their own raw materials when decorating." Jun Youyao added.

Liao Boyan was grateful, "Thank you so much for you and Professor Chi, this is really helpful." ”

Jun Youyao shook her head, "It's all about catching the murderer as soon as possible, and you don't want to thank us." By the way, according to Mr. Shen's profile, have you screened out suspicious people? His profile lock range is quite small, so it shouldn't be difficult to troubleshoot, right? ”

"Yes, yes." Liao Boyan also did not mean to hide it, "According to Consultant Shen's profile of the criminal, we initially locked up four people. ”

He opened the drawer of his desk and pulled out a report and placed it in front of her.

Jun Youyao took a quick look at it, and there were two men's resumes and investigation descriptions in this report, both of which were preliminarily consistent with Shen Qianxing's profile of the criminal.

Both of them are mature and attractive men, with a certain influence in the entertainment industry, and both have medical-related experience, one studied at a well-known medical school but later dropped out, retook the art of directing, and has made several movies in recent years that are not popular but have a decent reputation.

The other is an amateur photographer, who used to be a doctor, and his patient died of a medical malpractice because of his improper operation, so he was dismissed from the hospital, and by chance he got involved in the photography circle, although he was not a professional, but he was still called "one of the photographers who can capture the beauty of male artists" by insiders, adding that this person is a gay.

Jun Youyao scanned the information of these two people, looked up and asked him, "Judging from the information you have so far, which of these two people is more suspicious?" ”

Liao Boyan sighed abruptly, "Both of these people have alibis, this one Hu, he has been filming movies in other places at the time of the crime, and the crew can testify to him, confirming that it is impossible for him to conduct research and kill people in the imperial capital some time ago and then throw away the body, as for that Yang, on the day Cai Li disappeared, he was photographed dating a male model in a bar on Qinghai Road, and stayed at the male model's house that night, and the male model had already testified for him. ”

"So these two people are no longer suspected, that is, the case has entered a dead end again." Jun Youyao thought of the situation in his previous life and was not surprised by this situation at all.

If the killer could have been locked down so easily, the case would not have been pending ten years later.

It's not that Shen Qianxing's profile is problematic, but the profile is not a clear evidence after all, criminal psychology is the process of collecting data, analyzing and interpreting the data from the perspective of psychology to understand the crime problem in society. The scientific research of criminal psychology has three obvious characteristics: first, the research objects are complex and heterogeneous; second, research is more influenced by personal factors; The third is the uncertainty, contingency and uniqueness of the research object.

These characteristics also contribute to the fact that sometimes there are many problems left out in the offender's profile.

So even if there are more people in this case now, who she has never been involved in in her previous life, it doesn't seem to lead the whole thing in a brighter direction.

Also, it's not that she will always find out about the victim's problem, her appearance is at most to expose this clue early.

What makes Jun Youyao a little anxious is that there are not only three people who suffered in this serial murder case in her memory, but five, which shows that if they can't catch the murderer as soon as possible, at least two or even more victims will die at the hands of the murderer.

"Have you reported any missing female artists recently?" One of the characteristics of this murder case is that the victims disappeared for a period of time before their bodies were dumped.

Liao Boyan nodded: "At present, there are indeed three whose whereabouts are unknown, but it is not certain whether they are missing, their economic company said that they took a period of vacation to repair before, and they may have gone on vacation, and in order to avoid harassment from the outside world, they usually cut off contact with the outside world, and they will not appear until the end of the holiday." ”

"But we checked the entry and exit records of those three people and made sure that they are still in China."

Jun Youyao unconsciously tapped the folder with her finger and asked, "Can I ask who these three are?" ”

Although I don't understand why she asked this, Liao Boyan still nodded and replied: "A young model named Shu Zhouzhou, 21 years old, the phone was turned off three days ago, and no one can be found at home, but her colleagues and friends said that her private life was chaotic, and she disappeared twice in three days, and this is not the first time; One is named Yu Wen, 20 years old, a rookie actor, who proposed to the company a week ago that he would go out for a period of time to experience life and hone his acting skills, but he has not heard from him since; The last one is also an actor, Yuan Ruojin, but she is 27 years old, and she is also more famous than the previous two, she just finished filming a TV series recently, and asked for leave to go on vacation, and her agent hasn't called her for four days. ”

Shu Zhouzhou?

Not impressed.

Yu Wen?

Neither is it.

Yuan Ruojin?

Yuan!

"Team Liao, if you believe me, you can focus on finding Yuan Ruojin's whereabouts, I think she may have been taken away by the murderer."

Liao Boyan was puzzled when he heard this, "Can I ask why?" According to the law of the murderer's selection of the victim, shouldn't she be the first to be excluded? ”

Jun Youyao thought about it and found a reasonable explanation for her words: "You just mentioned that Yuan Ruojin's agent called her for four consecutive days, but no one answered, which shows that she is not usually a person who willfully plays missing, so even if her agent knows that she is going on vacation and may just turn off the phone for quiet, she still subconsciously feels that something is wrong." ”

"Besides, the range of choice of the victim itself is not inevitable, the murderer in this case is a high-IQ organized criminal, he selected the victim for experiments, not to meet his mental or physical needs, so for the sake of experimental materials, he will lower his selection criteria."

"And in addition to Yuan Ruojin's age being a little older, she has a little more to attract the murderer than the other victims."

Liao Boyan was busy asking curiously: "What is it?" ”

"She's stronger." Jun Youyao recalled the information about Yuan Ruojin, "She used to be a volleyball player and changed her career to become a martial arts actress, and she has a physical advantage that other young girls don't have. ”

Liao Boyan seemed to be empowered by Daigo, clapped his hands and stood up, "Miss Jun, you're right, I'll let someone check Yuan Ruojin immediately." ”

Jun Youyao also stood up, she had already done everything she could.

Now it is probably only left to pray that God will let the fourth victim show up as late as possible.

Liao Boyan thanked her again and patted the document she had just given him, "I also hope that this clue provided by Miss Jun can provide us with a new direction of investigation." ”

"Good luck."

***

God probably didn't hear Jun Youyao's prayers, and on the fourth day after the third victim was found, not only did the fourth victim appear, but even the fifth victim appeared as well.

At six o'clock in the morning, when Chi Yuling received the notice, he and Jun Youyao were testing alanine aminotransferase in the victims' livers all night, trying to find out what kind of human experiments the murderer was conducting.

"Youyou, bring the tools, we have to go to the scene." Chi Yuling put down his phone and looked at Jun Youyao, who was staring at the microscope seriously.

Jun Youyao raised his head and frowned, "There is a dead person again?" ”

Chi Yuling looked solemn, "Team Liao said that two female bodies were found in the fitness area of Jinping Community on the outskirts of the city. ”

"Two?" Jun Youyao was surprised.

When they arrived at the scene, the cordon was full of people, including the media.

When Liao Boyan's little policewoman saw them, she hurriedly ran over to greet them, and the little policewoman was the first one to see the victim's aging a few days ago, named Xu Jia.

"Professor Chi, Miss Jun, you are here." Xu Jia was sweating profusely and looked very anxious.

Jun Youyao glanced at the crowd blocked by the police outside the cordon, frowned and asked, "Why did so many media come?" The PR department didn't intervene? ”

In the first three murders, public opinion was blocked.

Xu Jia sighed, "It's not that I didn't intervene, but I intervened but the effect was not good, the reason is that you will know when you see the victim." ”

Jun Youyao heard the meaning of her words, it seems that one of the two victims this time may not be an ordinary artist.

She thought she was mentally prepared, but she really didn't expect to see acquaintances among the victims of this case, and there were two of them - the deceased were Qin Zhiya and An Susu.

She stood on the trampled lawn, watching the cold and white bodies of the two people being thrown to the ground like rag dolls, they should have been very scared before they died, and there were still frightened expressions on their faces.

But that's not right.

How could it be An Susu and Qin Zhiya?

In her previous life, she had never heard that these two people would die in this murder case, could it be because of her butterfly? She sunburned her wings too hard and fanned these two out of the game?

And putting aside Qin Zhiya, a well-known female artist, what's going on with An Susu? She can't get along with the entertainment industry at all, how could she die at the scene of a serial murder of a female artist?

What went wrong?

“…… Youyou? What's wrong with you?" Asked her for tweezers and a physical evidence bag for a long time and didn't see her react, Chi Yuling looked at her with some confusion from her head, and it was really rare to see this child wandering on a critical occasion.

Jun Youyao came back to her senses, saw the teacher's worried gaze, and hurriedly shook her head and replied, "It's okay, the tweezers and the evidence bag, right?" I'll take it right away. ”

Now is not the time to analyze why Qin Zhiya and An Susu became victims, she put on rubber gloves, opened the portable toolbox, and quickly handed the tweezers and physical evidence bag to Chi Yuling.

He quickly collected small objects left on the surface of the corpse, such as broken hairs embedded in the corpse's fingernails.

"Mr. Chi, can you tell the time of the victim's death?" Liao Boyan finally finished dealing with a wave of media at this time and walked to the two of them.

Chi Yuling replied after measuring the liver temperature: "According to the liver temperature and corpse spots of the two corpses, this deceased should have died between 2 and 4 o'clock in the morning last night, and the other has already appeared corpse green, she should have been dead for more than 24 hours, and the exact time of death needs to be further autopsied to determine." Both victims, like the previous three victims, had part of their left chest cut off their flesh and had their hearts removed, but it is uncertain whether they were committed by the same killer. ”

Death for more than a day is Ansusu.

Jun Youyao opened the eyes of heaven and observed the two corpses, Qin Zhiya's situation was indeed consistent with the first three victims, the appearance of death, and the cause of death were all the same.

But ansul......

"Team Liao, have these two corpses been touched?" Jun Youyao squatted in front of An Susu's corpse, and when she and the teacher arrived, the two corpses were lying side by side, very neat.

"How do you know?" Liao Boyan was a little surprised, and did not understand how she could see this, until the forensic medical officer arrived at the scene, the police and forensic technicians would not move the body without permission.

Jun Youyao didn't answer, "What did you say first?" What were they supposed to be? ”

"That's right, the first discoverer was an old scavenger, and when he found them, the bodies were covered with a Persian carpet, so he didn't find two corpses here at first, he wanted to pick up the blanket, grabbed a corner and pulled, but he didn't expect that part of the carpet was pressed by the corpse, and when he pulled, he not only exposed the corpse, but also pulled the corpse, so you guessed right, the corpse was indeed moved."

Jun Youyao nodded clearly, "An Susu's corpse should be the one wrapped in the carpet, right?" ”

Liao Boyan was shocked again, not only because she was right, but also because, "Do you know this deceased?" ”

He had just confirmed that among the two deceased, Qin Zhiya was a celebrity in the entertainment industry and the eldest lady of the Qin family, while the other person was not an artist, but the youngest daughter of An Qinglian, president of An's Group.

By the way, Jun Youyao and the An Group do seem to be related, and he felt stupid as soon as he asked this question.

Jun Youyao saw that he looked like 'I asked a stupid question', and knew that she didn't have to answer his question, but she still said: "My mother is married to her father, so we are also nominally ...... Sisters. ”

Of course, this sentence was explained to Chi Yuling, and he, an old man who was addicted to medicine, obviously did not deliberately pay attention to the private affairs of his students.

Only then did Chi Yuling understand why she was distracted just now.

It turns out that there is still this relationship.

But looking at this child's appearance, her relationship with this An family should not be good.

"Miss Jun, you asked about the location of the corpse, did you find any problems?" Liao is more curious about this now.

"Well, there's a little discovery." Jun Youyao picked up An Susu's hand, "Her corpse spots are deposited on the front in a large area, which shows that she was originally thrown here face down, but when we arrived, she was lying flat, and there is the blanket on her body, which has never appeared in the first three cases, she is very special, so special that the cause of her death is different from everyone else." ”

Liao Boyan and Chi Yuling were surprised when they heard this, "The cause of her death?" ”

"Qin Zhiya won't mention it for the time being, but An Susu definitely didn't die of myocardial infarction like the previous three victims, she died of air embolism."

She opened the position of An Susu's chest, her heart was removed, but her lungs were still there, and Chi Yuling quickly noticed the problem, "The murderer injected a large amount of gas into her heart, and the air entered the blood vessels to cause air embolism, and the body's blood flow was interrupted and died." ”

"Obviously, this murderer knows a little medical knowledge, but he doesn't know it thoroughly, he knows how to kill people with this method, but he doesn't know that this method can find out the cause of death of the victim as long as the forensic doctor examines the blood vessels and lungs."

"To sum up, I think the murderer of An Susu and the murderer of the female artist serial murder case may not be the same person, this is a somewhat stupid imitation murder."

“……”

The bodies of the two victims were quickly transported back to the police station, but Liao Boyan was entangled by the crazy media, and Qin Zhiya's death finally put the case on the cusp of public opinion.

The media are like bee eagles that smell the sweet smell of honey, aiming their long guns and short guns at the police and the families and friends of the victims, and you don't need to imagine what kind of bloody storm will ensue.

After the media reported that the murderer's murder was limited to female artists in the entertainment industry, the female artists in the entertainment industry were panicked, and they all seemed to be suffering from victim paranoia, and sometimes they would call the police and say that they were being followed, which brought a lot of work to the police in the imperial city.

This is a later story, so I won't show it for the time being.

Soon after Qin Zhiya and An Susu's bodies were sent to the police station, the Qin family and An Jinyu arrived, An Qinglian and An Wanwan did not appear, they were not in the imperial capital, and it was estimated that it would take several hours to get to the scene.

Director Li personally brought them over to identify the corpses, and it was Qin Zhiya who saw them.

The Qin and An families are considered in-laws, so An Jinyu also followed.

At that time, Jun Youyao was wearing a neat autopsy uniform, hat, gloves, and mask, so none of these people noticed her when they entered the door.

She saw Qin Rong in this group of people.

She hasn't seen her since Ai Fusheng auctioned off Pingren Hospital.

She looks more beautiful than before, just like her facial features have grown, more beautiful and dazzling, youthful and dazzling, and more and more close to the Internet celebrity face of later generations, given that her real identity is not Qin Rong but Huang Tiantian, her face should have been knifed again, the corners of her eyes were opened, the apple muscles were filled, and the chin was sharpened.

She was leaning on An Jinyu's shoulder at this time, sobbing constantly, the tears on her face were rolling down like a spring, and everyone felt that she was grief-stricken because of her sister's tragic death.

She cried so much that she was depressed and painful, and I felt pity for her, which made people feel related.

In terms of acting skills, in addition to Mo Chenxi's drama essence, she was convinced of Qin Rong, I heard that she has now officially entered the entertainment industry, and recently got an important supporting actress role in the new movie directed by Zheng Bao Guoda, and her sister Qin Zhiya is the heroine, Mo Chenxi is the male lead, and a number of big names have confirmed to join the cameo.

Big production, famous director, top traffic star, this film became popular before it was filmed, and Qin Rong also took advantage of this to stir up a wave of popularity.

But now that the film has not started filming, the heroine Qin Zhiya is dead.
