Zhuang Yi got up and zoomed in on the details of the picture: "It is not difficult to see that the victim has various wounds, some of which are very brutal. To restore it, there may be slaps, kicks on the abdomen of the suspect, and wounds on the head. Injuries, etc."
He pointed to another picture, "The scars here indicate that the murderer violently dragged the victim."
Having said that, Zhuang Yi zoomed in on a few more pictures of the victim's face: "But look at this again, the makeup is very carefully painted, the foundation covers up the scars on the face, and the lipstick is applied so that it completely covers the lips, the inside is dark and the outside is shallow. , is overly natural, and I can say that most men do not achieve this level of proficiency.”
"And here..." Zhuang Yi pointed to the detailed picture of the second case, "The murderer put clothes on the victim and carefully tucked them in. There were several ropes on the victim's clothes, among which The way one bow is played is completely different from the others, so it can be seen that it is the murderer."
At this time, the female corpse on the projection had a delicate face and neat clothes, which confirmed his statement. Tian Ming nodded lightly when he heard this. They have been investigating the case for some time, but many of the details have not been carefully analyzed.
As Zhuang Yi spoke, he also circled some other details with a red pen: "These... and these, may all be done by the murderer... But isn't it surprising? These behaviors are like paying attention to appearance. Only a perfectionist would do it, a violent man, a brutal murderer, why would he do these things. What is the purpose of him doing these things?”
No one answered, there was silence in the conference room, and all the police officers present fell into deep thought. In the case, these details are indeed very strange and cannot be explained by common sense.
Lu Siyu looked at the projection. He had noticed these details before, but he didn't think of a good explanation for a while. At this time, he turned his head and waited for Zhuang Yi to continue.
"Looking at these pictures, it is not difficult to imagine that a person is kneeling in front of the female corpses, helping them with makeup, and tidying them up carefully and cleanly... But before that, he has completed all the criminal processes, normal When the prisoner reaches this point, he either turns around and leaves contentedly, or thinks about how to hide the corpse, and what motivates the murderer to organize the victim's makeup?"
"These are two completely different behavioral modes. One is rough and violent, the other is nuanced." Looking at the projected photo, Gu Ju said.
He also felt that there seemed to be some indescribable strangeness in those pictures. Now that Zhuang Yi has analyzed it, he finally understands where the abnormality is.
"About this case..." Zhuang Yi paused and said, "I have a bold guess. We may have two suspects."
"Two?" Gu Ju repeated these two words, frowning and wrapping his arms.
This Professor Zhuang, as expected, was so speechless that he threw out such a terrifying theory as soon as he came up. However, such a conclusion, under his previous foreshadowing, makes people feel reasonable.
"I put forward this theory because I found two contradictory behavioral logics in these live photos. One is unbridled, unrepentant, and intensified violence; the other is regret, pity, guilt, remorse..."
Zhuang Yi talked eloquently, like a professor who lectures to students in a university, he walked to the front row and put his arms on the table: "It is true that these two emotions can appear in one person, but because of These two emotions are contradictory. According to common sense, one should be strengthened and the other should be weakened. It is like the more sad a person is, the more happy it is impossible to be at the same time... "
Everyone present looked at the photos of the three groups of victims. As he said, in the three cases, the girls were getting younger and younger, and the injuries were getting heavier. Correspondingly, their costumes also became more and more serious. more refined. When he arrived at Wang Xiaopei, he was meticulous and spent a lot of time.
"But now, with the progress of these three cases, these two opposite emotions are progressing. The more violent, the more guilt, and the newest victim, the murderer even risked being discovered. , to make up for the victim's makeup."
Speaking of this, Zhuang Yi concluded: "That's why I came to a possible conclusion that there may be two murderers we are looking for."
Then he analyzed in detail, "We can know from various details that the main culprit is a male, aged between 20 and 30. According to the shoe print measurements on the scene, the height should be about 1.75 meters, with a medium build. , his muscular build, his enough violence, broken ribs, bleeding eye sockets, strangulation, all illustrate it well."
"The support person may be a thinner female or male who is responsible for baiting the victim to let their guard down. Or he simply doesn't show up at the scene of the murder and just waits until the end of the crime to clean up the mess. He may be weaker. Female, also cannot rule out the possibility of male. He should be coerced, or semi-coerced, not completely willing, he is careful, timid, perfectionist, he is using behavior to make up for the harm done by the murderer to the victim. He will give After the victim was dressed and made up, he felt pity and guilt, and would cover the victim's face with his clothes. He may have lacked the care of his parents since he was a child, could not live independently, and was dependent on the principal."
Zhuang Yi said here and summed up: "These two people, one is active and the other is passive, like a pair of embarrassed combination."
After he finished speaking, the expressions of Tian Ming and others changed. Such an inference was a situation they had never considered in the past few months. But what Zhuang Yi said seemed to make sense.
"Strangulation and assault are very private crimes, and there are few accomplices." Gu Ju frowned deeply, "Then why do you think this happened?"
Zhuang Yi continued: "People's relationships are intricate and complicated. Such a combination may be a family relationship or some kind of internal relationship, such as a wife who was abused to help her husband, or an older brother helping an out-of-control younger brother to clean up the mess, or a mother who could not The son who controls his own violence, maybe even a father and son…”
Zhuang Yi turned around and said: "If you think it's unbelievable, I can give some examples. In the past, there have been cases where a pregnant wife went to help her husband hunt for beauty. The murder of a pig farm in Vancouver was done by a brother. As for the parents' help There are countless examples of sons covering up the facts of murder."
When Zhuang Yi said this, he turned to look at the projection: "Of course, these are just my personal thoughts after seeing the pictures, the theory is not very mature, it's just a hypothesis, and the specifics have to wait for the police to investigate. I hope There can be actual physical evidence, or testimonial testimony can justify my theory."
At first, everyone didn't quite believe it, but after he gave those examples, several people nodded and accepted this possibility. This behavior pattern is understandable.
Lu Siyu was silent on the side, and recorded Zhuang Yi's statement on the paper.
Song Wen lowered his head and pondered for a moment, but still felt that there was something inexplicable about the two people committing the crime, and a flash of light suddenly flashed in his mind: "That... Is it possible that the murderer of this case has dual personalities?"
The conference room was quiet again for a while, and even Gu Ju began to frown and ponder. If the murderer had a dual personality, it seemed that Zhuang Yi's previous analysis could be satisfied.
Tian Ming's stubborn man thought this kind of argument was a bit incredible, "Song team, you're saying this is a bit too special..."
However, Zhuang Yi interrupted Tian Ming's words and cast an approving look at Song Wen: "This idea is very good, and I have also considered this situation."
When Zhuang Yi got here, he turned to face the crowd and answered the questions in their hearts: "Double personality, the scientific name is called 'dissociative identity disorder'. In fact, although dual personality is rare, it is not uncommon. Consider this situation Go in, it's very comprehensive. It's just…”
Zhuang Yi paused and continued to explain: "Dual personalities, you cannot choose or switch personalities at any time."
"Most of the personality transitions are carried out randomly. The regular transitions are closely related to traumatic events. When encountering large stimuli, stressful events, or extreme relaxation, For example, close to sleep, after hypnosis, the fixed change will occur."
"In this case, the gentler character with a sense of guilt appeared after the crime. If we assume that the murderer really has multiple personalities, then at this time, his emotions are often down but not relaxed enough, and his nerves are tense. When I was here, I repeatedly reasoned here, but I couldn't find the point of his personality stress transformation and the reason for the stress transformation."
Having said this, Zhuang Yi pulled the whiteboard and said, "I analyzed the psychological process of the murderer's crime. According to the theory of psychodynamicist Lewin, we divide the psychological motivation into six basic links: need, tension, valence, Vector, obstacle, balance."
"These six stages can be well applied to this case. Needs are physiological needs. Tension is internal tension. Valence is subjective experience. Vector is a measure of conflict. Obstacles are our rule of law. , the law, the power to hinder behavior. At last there is balance, and the murderer is satisfied.”
Zhuang Yi drew a circle on the whiteboard and wrote the six states respectively.
"People's behavior develops from need to balance. I think by the time the victim dies, the final equilibrium is over. Only before the next attack will the next cycle occur. In other words, ordinary people It is understandable to say that the murderer should be in the state of a sage at this time, and there is absolutely no reason or possibility for conversion."
"So I don't think this situation fits well with the three cases that have occurred."
Song Wen nodded and accepted this explanation. Without stress points, it is impossible to complete the fixed personality transformation. If the fixed personality transformation is not carried out, the characteristics that are formed in each case cannot be created. The theoretical assumption of dual personality has obvious loopholes in this case, and it is untenable.
The case analysis was almost the same, Gu Ju turned around and asked Tian Ming, "Team Tian, what do you think about this?"
Tian Ming said: "Although there is not enough evidence on the scene to prove that the suspects are two people, I think Professor Zhuang's analysis is in line with the situation at the scene."
"Thank you Professor Zhuang." Gu Ju pondered for a moment and said, "This theory is a bit interesting. I think this analysis is reasonable. It cannot be ruled out that there are two or more murderers. You will investigate the case next. When the time comes, you can take this situation into account and conduct an investigation to see if there is any gain.”
Then he looked at everyone and said, "You are all elites of the Municipal Bureau. You must work together to catch the perpetrator as soon as possible. You must race against time to ensure the safety of the citizens."
