"Let's look at the height and appearance of the four known victims." Yu Zheng opened the next slide.
"Li Liwei, 31 years old, 166cm tall and 51kg in weight.
"Wang Wei, 24 years old, 165.5cm tall and 49.5kg in weight.
"Wang Qianqian, 24 years old, 167.5cm tall and 53kg in weight.
"Ding Jing, 26 years old, 167cm tall and 52kg in weight."
He smiled again: "The four victims are all young women with beautiful appearances, but the most crucial point is that the four of them are all very close in body."
He wrote down the third common denominator—“physique.”
"Why didn't I think of this!" Xiao Zhou turned his head to look at Jiang Chengyi in surprise. No wonder Team Jiang specially asked him to highlight the victim's height and weight. It turned out that Team Jiang had already noticed this.
"Let's look at the next one."
Two cartoon stickers side by side appeared on the screen, both with butterfly patterns, the one on the left was worn and dim, and the one on the right was bright and new.
After staring at the butterfly for a few seconds, Yu Zheng turned his head and cast an admiring look at Jiang Chengyi: "This is the clue that interests me the most, and it is also an important entry point for profiling the criminal. Because this kind of physical evidence is very inconspicuous, it is very easy to be ignored in the process of handling the case. Fortunately, Jiang team did not make such a mistake, not only did they go to Wang Qianqian's house for a second search, but also kept it as physical evidence. "
Xiao Zhou Yu Yourongyan: "Jiang team is my senior, and he was the top student in our school back then."
Yu Zheng smiled, then continued: "Although this kind of butterfly sticker can be bought everywhere in the market, it cannot be considered that the murderer put it into the victim's home, but considering the sense of ritual at the scene of throwing the corpse, I Let's assume it was distributed by the murderer.
"The sticker on the left was found from Wang Qianqian's house. The second sticker was pasted on the door of the witness surnamed Lu who ran into the fake Deng Man.
"Coincidentally, judging from the surveillance video, the woman who was at the door of the witness surnamed Lu that night was very similar to Li Liwei's dress - wearing an orange H brand silk scarf, coat, ankle boots, if I remember correctly, the information The above shows that Li Liwei was also wearing this dress when she was killed. Of course, if the Jiang team just took over Li Liwei's case and looked through Li Liwei's case, it is estimated that they would not have noticed this. Unfortunately, because the murderer knows how to avoid the blind spot of surveillance, Failed to trace.
"However, based on this, it is not difficult for us to associate that what the witness who called the radio station said was not fabricated, and there was indeed someone who pretended to be Li Liwei to haunt at night. Direct and objective evidence."
Lao Qin suddenly realized: "According to what Dr. Qin said, the fake Deng Man that Dr. Lu bumped into that night is likely to be the murderer. According to Dr. Lu, the time when he met that person was after one o'clock in the morning, and the time of Wang Qianqian's murder was 23: From 00-1:00, the murderer committed the crime and was accidentally bumped into by Dr. Lu. The murderer was afraid that he would be exposed, so he started to follow Dr. Lu the next day, put up butterfly stickers, and listed her as the next target?"
Xiao Zhou wondered: "No, the murderer imitated Li Liwei and stole Wang Wei's clothes. It's all right, but didn't that Deng Man commit suicide? Why did the murderer imitate Deng Man eight years later, and what was the purpose?"
"That's why I said that the cause of Deng Man's death must be suspicious." Lao Qin said to Yu Zheng, "Dr. Yu, please continue."
Yu Zheng turned his head to look at the screen: "Unfortunately, three years have passed since Li Liwei's case, many physical evidences have been lost, and no butterfly stickers were found in Ding Jing's house, but this does not prevent me from believing that this is a signal left by the murderer. Because if this link is missing, the meaning of the corpse floating in the water will become unclear. Next, let me ask a key question - Team Jiang, you have seen the witness surnamed Lu, can you tell me How tall and heavy she is."
"167cm, about 50kg." Jiang Chengyi answered quickly.
"What about the appearance?"
"pretty."
Yu Zheng couldn't wait to applaud: "Very good. The murderer is a perfectionist, and he has been strictly implementing his series of requirements for selecting victims over the years. If he just wants to kill witnesses, the murderer will not distribute butterfly stickers to witnesses surnamed Lu. Distributed, it shows that he is already considering whether to list the witnesses surnamed Lu as the object of the next ceremony."
Jiang Chengyi couldn't sit still. Lu Yan is staying at home at the moment. Although his mother, sister-in-law Liu, and the driver are all there, and the driver has been trained, he still feels uneasy after thinking about it.
After pondering for a few seconds, he called Xiao Zhou to come forward and whispered a few words.
Seeing that Xiao Zhou was reluctant to leave, he assured Xiao Zhou: "You go first, and I will let Lao Qin listen to the recording materials for you when you come back."
After Xiao Zhou left, Dr. Yu continued: "Butterfly, called 'psyche' in Greek, has a double meaning of love and soul, and also symbolizes transformation and rebirth.
He walked over to the whiteboard and drew a butterfly pattern, then said to Lao Qin, "please play back the slideshow."
When the image was frozen on the white waterproof bags of several victims, he asked Lao Qin to stop.
"According to several witnesses, the body of the victim was floating in the middle of the lake. Because it was wrapped in white waterproof material, it looked white and dazzling even at night. According to the information, the person who found Ding Jing's body of the witnesses once used the 'fetus floating in amniotic fluid' to describe the sighting scene. I think if the murderer hears this description, he should be very proud, because he has basically presented the criminal beauty he wanted. In fact, from the photos Look, the victim is not only like a fetus, but also a little like a chrysalis, but no matter what kind of image the murderer wants to present, there are hints of 'new birth', 'rebirth', and 'transformation'. Water, there are 'hatching', 'incubation' The meaning of 'washing', 'cleaning'."
Jiang Chengyi captured one of the words: "Reconstruction?"
"Yes. The murderer selected a group of people as the target, followed and killed the other party, and reluctantly fine-tuned the corpse dumping site. From researching buoyancy, purchasing packaging materials to investigating the corpse dumping site in advance, the murderer has gone through almost every step of precision. He calculates again and again, again and again, until he achieves the desired effect. We all know that the learned mechanisms of criminal motives are divided into reinforcement mechanisms, self-reinforcing mechanisms and punishment mechanisms. From this series of cases Look, in the past few years, the murderer has completed the evolution from the reinforcement mechanism to the self-reinforcing mechanism, the criminal impulse has gradually escalated, and the frequency of crimes has become higher and higher."
"No wonder." Lao Qin scratched his head, "It has been three years since Li Liwei's case with Wang Wei in City B, and four months later, Wang Qianqian's case came out, and only a few days have passed between Wang Qianqian and Ding Jing. In other words, the next victim will appear soon? Team Jiang, we have to catch this pervert quickly."
Dr. Yu: "Continuing to say, from the cycle of selecting victims - setting up the scene - imitating victims, the murderer has achieved a high degree of affirmation of his own behavior, and from this series of behaviors, he has gradually accumulated more and more criminal pleasure. I Guess, after every successful crime, he rewards himself in some way."
After speaking, he pulled out the chair and sat down, smiling like Mona Lisa: "Everyone should have heard of the case of Arthur Shawcross, after this murderer was born, eleven women have encountered this demon one after another. At that time, it was precisely because of the psychologist's profile that the murderer was finally caught, but this case is fundamentally different from that type of sexually perverted serial murder case.
"The first and fourth victims showed no signs of being sexually assaulted. Second, except for the strangulation marks on the neck, the corpse was not damaged and preserved quite intact. Third, after the death of the victim, the murderer seemed to imitate it intentionally. What the other person is wearing. Assuming that last point is a way for the murderer to intoxicate and reward himself, I have reason to believe that there is another intention involved in his motives—replacement.”
Some people said they didn't understand: "Dr. Yu, this is too convoluted, can you explain it to us in vernacular."
Dr. Yu was approachable, and immediately changed to a slightly more popular expression: "OK. Let's go back to the four victims themselves. In addition to being similar in physique, these women should also have other things in common, such as gait, and add them together to make the murderer. A criminal association is produced, but these points alone are not enough to initiate the murderer's 'criminal stimulus situation'.
Lao Qin couldn't hold back, and interjected: "From the information we just found, at the beginning of the Winter Solstice website, maybe it was for fun, Ding Jing was the first to make a wish on the website, that is to say, including Ding Jing. Including Jing, the four victims have all made wishes on the Winter Solstice website. Dr. Yu, even if you say, the victim's wishing behavior may not be directly related to their murder, but it does not mean that it is irrelevant. Can you give us an analysis on the website?"
Dr. Yu wrote the word "Wish" on the whiteboard.
"Very well, let's try to add another hypothetical factor - the Winter Solstice website. Everyone here must know that there is only one kind of person who can satisfy the desires of human beings in both Western and Eastern cultures. In the West, we call him God, in the In the East, we call it God."
Silent.
Yu Zheng's eyes faintly revealed the brilliance of a hunter: "I don't know which year the murderer started the crime, but judging from his insistence on choosing women of the same physique as his targets, the victim's physique will change. Reminds him of a certain woman he knows and hates—wife, mother, superior, teacher, female relative, etc., and this is the first condition he must meet in his selection of targets.”
Jiang Chengyi pondered and said: "In the past eight years, the Winter Solstice website has accumulated more than 100 users who have drawn the most difficult card to draw, but so far only four victims have appeared. I thought it was a bit puzzling, but With that in mind, it makes sense.”
Yu Zheng: "That's why I said that this criminal is a perfectionist. For him, crime is a complete and continuous process, and several elements are indispensable. I speculate that the murderer wants to gain control from the victim. Therefore, this element is realized by satisfying the wishes of the other party. Although the Winter Solstice was founded eight years ago, it was not until three years ago that the first victim, Li Liwei, who satisfied all the elements appeared. It is said that it was not until three years ago that the murderer had enough financial strength to satisfy the wishes of the victim and then commit a series of crimes. Do you have any objection to this?"
Lao Qin nodded hurriedly: "Dr. Yu, please continue."
"Okay, let's talk about the second point. After committing the crime, the murderer wraps the victim's corpse into a fetus or chrysalis and throws it into the water. From a psychological point of view, this behavior implies 'destruction', 'transformation', 'rebirth' and 'Washing the other party's sins' and imitating the other party's clothes means 'admiration' or 'replacement'. Judging from the calmness of the murderer when he committed the crime, I tend to prefer the latter - substitution.
"In addition, based on some unknown incentive, the murderer firmly believed that the target he selected did not 'need to exist' in the world and must be 'rebuilt'. After satisfying the other party's wishes, he believed that he had The relationship of the other party has changed, and he has become the master of the other party, who can arbitrarily dominate and even destroy the other party's life. After completing the chrysalis/fetus ceremony, he believes that the other party's sins have been washed away, and he has become a new born, so he Only after the fact will have the pleasure of imitating the other person's dress and repeating the process."
Jiang Chengyi put down his pen and presented the paper in his hand to Yu Zheng, asking him to correct him: "Look at what else you need to add."
Yu Zheng squinted his eyes and wrote on the paper: 1. Male. 2. Have a good economic foundation. 3, thin body. 4. High cultural literacy. 5. Exclude gangs from committing crimes.
After the analysis just now, there is no need to repeat it with a long discussion, everything is in it.
"Excellent." He nodded again and again and said to Jiang Chengyi very sincerely, "Jiang team, this is the most complicated criminal motive case I have come across in recent years. I have developed a strong interest in the criminal's personality. If caught Criminal, I hope to have an in-depth conversation with the criminal."
Jiang Chengyi shook hands with him: "Thank you Dr. Yu for your help. With your profile, we plan to narrow down the scope of finding the murderer. If we encounter other problems, we may trouble Dr. Yu."
"You're welcome." Yu Zheng's eyes lit up, "I don't need to say hello from Team Jiang, I will take the initiative to follow up on this case."
Lu Yan was sitting on the sofa talking to Jiang Chengyi's mother. Although she always kept a decent smile, she knew how hot her face was.
I don't know if Jiang Chengyi did it on purpose. She didn't tell her where the washing machine was when she left. While she was still walking around the house with the sheets, Jiang Chengyi's mother came.
The most embarrassing thing is that when Sister Liu took the sheets, Jiang Chengyi's mother "accidentally" caught a glimpse of the large pool of traces, and suddenly her mouth became round in surprise.
Lu Yan was at the side, so embarrassed that she could not wait to get into the cracks in the ground. Last night, she and Jiang Chengyi came back and forth five or six times without taking protective measures.
Jiang Chengyi's mother seemed very excited. First, she immediately instructed Mrs. Liu: "Put what we brought into the refrigerator in a while."
Then he pulled her to sit down on the sofa, and looked at her with a smile: "Good boy, what do you want for lunch? Fly in the sky, walk on the ground, as long as you want, Mrs. Liu can do it for you. Auntie is nothing else. If you choose, choose your cooking skills, Mrs. Liu has been by my side for so many years, and she has long been honed."
Although Lu Yan's face was still hot, she tried to make herself smile as naturally as possible: "Auntie, I don't pick anything, everything tastes delicious."
"It's so good." No matter what Lu Yan said or did, Jiang Chengyi's mother was extremely satisfied, "It's not like Jiang Chengyi, Yanyan, you don't know, now he's a lot older, he was picky when he was a child, just a little bit He won't eat anything that smells fishy."
Naturally, she changed her name and called Lu Yan "Yanyan", and she became a little closer without realizing it.
Seeing Lu Yan smiling, Jiang Chengyi's mother said, "Jiang Chengyi called his father's secretary in the morning and asked the secretary to help you book air tickets and hotels for the two of you. This kid has a good eye. Salzburg. But then he seemed to be busy, and he didn't set a specific time. What, the two of you are planning to travel recently?"
Salzburg
Lu Yan was taken aback. When she was still in high school, she read a novel once and saw that the place was so beautifully described in the book.
"Maybe I want to give you a surprise." Jiang Chengyi's mother seemed to regret her blunder, and immediately smiled and blinked, "You can quietly pretend that you don't know."
Saying that, he pulled her up and smiled: "Come on, let's talk inside. Auntie has something good for you."
Not long after entering the room, Xiao Zhou came, and Lu Yan rushed out of the room to open the door for Xiao Zhou.
Jiang Chengyi was busy until the evening before coming back. As soon as he came back, Mrs. Liu started cooking.
While waiting for the meal, Jiang Chengyi's mother talked to Jiang Chengyi, and Lu Yan sat on the side and drank tea with a smile, thinking about the things Jiang Chengyi's mother gave her. It has been more than an hour since just now, and her face is no longer hot at every turn, and she can think about the problem relatively calmly.
However, Jiang Chengyi is so stubborn, will she be tied to the bed and do whatever she wants? Just thinking about it makes it impossible.
Although Jiang Chengyi has been talking to his mother, Yu Guang always pays attention to Lu Yan. Seeing that Lu Yan is unusually quiet and has a confused expression from time to time when drinking tea, he can't help but wonder.
After dinner, it's past eight o'clock.
Jiang Chengyi came back after seeing off his mother and Xiao Zhou. Seeing that the living room and dining room were empty, Lu Yan did not know where to go.
He walked to his room, she was not there, came out, knocked on the door of her room, and heard her answer in a dull voice: "I'll take a shower first."
He stood at the door for a while and had to go back to his room.
After thinking about it, he simply went to the bathroom to take a shower.
But after washing and waiting in the room for a long time, Lu Yan didn't move.
Although he really wanted to stretch for a while, he thought that Lu Yan said that she was taking a shower, but he still couldn't stretch it and opened the door to go out.
Lu Yan had already taken a shower, but facing the "good things" in the bed, she felt a little ashamed in addition to having difficulty in choosing.
After picking and choosing, I finally chose the most conservative set of white lace to wear, and put on ordinary pajamas on the outside. Then I packed up and walked to the door.
As soon as he opened the door, he saw Jiang Chengyi standing outside, just about to knock on the door.
"What are you doing?" He looked at her, his voice was a little dull, his shirt and trousers were much more conservative than hers. The crystal lamp in the corridor, with heavy light and shadow, illuminated his unusually handsome face.
"Why?" She pretended to be calm, and when she came out, she naturally closed the door behind her.
