Department of Psychology Forensic

Chapter 35 The Murderer Will Kill?
After Zhou Zheng walked out of the forensic center, he went straight to the office of the criminal police team of the Municipal Bureau.

When he walked to the door of the office, he met a familiar figure.

Qin Wangde, deputy director of the Municipal Bureau.

"Uncle Qin." Zhou Zheng immediately greeted him. There is no one else in the corridor now, so there is nothing wrong with calling him this way.

"Xiaozheng, did you find anything over the corpse?" Qin Wangde also saw Zhou Zheng, and his expression didn't look very good, so he asked immediately.

"This is the forensic report." Zhou Zheng raised his hand and handed the document to Qin Wangde, shaking his head and said: "No more body parts have been found yet, and there are only so many things that can be identified based on the head, and there is nothing substantial. clue."

"This case is a bit tricky. The news has spread in Jianghai's university towns. The social influence is very bad, and our work pressure is also very high. I hope you can use the knowledge you have learned from Lao Fan to help us solve the case as soon as possible." Qin Wang There was exhaustion in De's voice.

"I will try my best." Zhou Zheng nodded heavily.

"Go, show the report to Xia Yan and the others. They are just about to have a meeting to summarize the information. You should follow along and listen to it. Everyone will brainstorm and find out the murderer." Qin Wangde patted Zhou Zheng on the shoulder and delivered the forensic report. Handed it to Zhou Zheng again, and then left with heavy steps.

"Ah."

Zhou Zheng watched Qin Wangde leave, he could clearly feel that the pressure on Qin Wangde's shoulders was heavy.

A series of homicides occurred during the short May Day holiday, which is a great challenge for the Jianghai Municipal Bureau.

Immediately, Zhou Zheng gently knocked on the door, pushed it open and entered the criminal police team's office.

As soon as he entered, he could feel the smoke lingering inside. Xia Yan was talking about the case in front of the small whiteboard.

"As of now, we have not confirmed the identity of the victim."

Xia Yan's voice echoed in the office. When he saw Zhou Zheng walking in, he nodded his head and continued talking.

"Because the incident occurred during the holidays, the art students of Jianghai Normal University did not have the habit of going to self-study. There were not many people in the entire teaching building, and no witnesses were found at all."

"The surveillance video retrieved shows that the murderer entered the teaching building of the art department with a black umbrella. Under the cover of the umbrella, he was completely invisible."

"The murderer is very familiar with the surveillance location in the teaching building of the Art Department. After entering the teaching building, he used an unknown canned spray to spray the camera under the surveillance, causing the surveillance camera to reflect light and not record anything. "

"The only thing that is certain is that the murderer was wearing a pair of black gloves."

"I think the murderer should have entered the teaching building first, sprayed the three surveillance cameras on the corpse throwing route, and then brought the mannequin upstairs."

"The exact time of dumping the body cannot be determined, but it is certain that it was between 6:38 and 9:51 this morning after the murderer covered the camera and before the reporter found the body."

"There is only one security guard on duty in the security room at the entrance of the teaching building. According to his confession, no suspicious person has been seen entering the teaching building. However, during this period of time, he once went to the bathroom to squat in the bathroom, but the specific He couldn't remember the time, and the murderer probably used this time to enter the teaching building to throw the body."

Xia Yan said one sentence after another, this was one of the few gains they had made during their investigation in the morning, and the whole case was still at a stage where they were at a loss.

"Our criminal police team has so much information at the moment, let the colleagues from the trace inspection department talk about it." Xia Yan nodded to Feng Yu who was sitting on the chair.

"Yeah." Feng Yu got up straight away, with the report in his hand, but he didn't hand it over to them, but walked to Xia Yan's position just now.

"The scene of the crime was in the piano room on the third floor of the teaching building. We extracted a total of 78 different fingerprints from the piano, glass, desktop, blackboard, walls, etc. in the classroom, and we are still comparing the repetitions among them. , however, no traces were extracted on the doll model at all, so..."

When Feng Yu said this, he pursed his lips, his expression was not particularly good.

"From the perspective of my work experience, I think the murderer is a cautious person. He didn't leave fingerprints on the model. He should be wearing gloves. Team Xia also said just now that the murderer in the video wore black gloves. We extracted The fingerprints obtained may have nothing to do with the murderer."

"We have extracted some subtle cosmetic residues from the fabric of the model's skirt, and we are comparing the chemical composition with the cosmetics extracted from the face of the deceased."

"If it is determined to be the same, it should be left behind when the murderer took the head, but if they are different, it may play a certain auxiliary role in investigating the murderer's residence."

"No trace of blood was found at the scene."

"There are many footprints at the scene, and they are incomplete. They are being identified, but there may not be much valid information. After all, this is a classroom, and it is normal for people to leave footprints."

"When we inspected the piano in detail, we found a mobile phone inside the piano. The mobile phone was in a locked state, with sufficient battery power and a SIM card inside. It is now being inspected by the physical evidence department."

"That's all we've found so far."

Feng Yu suddenly took a deep breath, his face suddenly became serious, and his eyes became a little complicated.

After Xia Yan and Feng Yu finished their investigations one after another, the criminal policemen at the scene all looked very ugly.

The difficulty of this case is beyond their imagination.

At least so far, they don't even know the identity of the victim, and the investigation of the case has reached a deadlock.

"Zhou Zheng, is there any result of the autopsy?" Xia Yan asked Zhou Zheng.

Instantly.All the eyes in the room were focused on Zhou Zheng, and everyone's eyes were shining with anticipation.

The more exciting the case is, the more they want to get a certain direction to solve it urgently.

"The cause of death was mechanical suffocation." Zhou Zheng raised his hand and handed the compiled forensic report to Xia Yan, saying, "That's all I can see."

"Is there no identifiable information about the source of the corpse?" Xia Yan asked.

"Female, long hair, no plastic surgery." Zhou Zheng thought for a while and said.

"That's all?" Xia Yan asked unwillingly, "What about your age?"

"Judging from the wear and tear of the teeth, the age is not very old, it should not be more than 30 years old, but I can't be sure." Zhou Zheng pondered: "There is too little information about the corpse. There is only one head, and it is still a damaged head. Even if there was any useful information on it to determine the source of the corpse, it was destroyed by the murderer."

"call……"

Xia Yan couldn't help taking a deep breath, now that after integrating the information, it can be said that he doesn't know anything.

"Now our first priority is to determine the identity of the deceased. Only after knowing the identity of the deceased can we proceed to the next step of the investigation." Xia Yan said: "Now we will expand the scope of the investigation, not only to investigate the disappearance of Jianghai Normal University female college students, but also to investigate the missing female college students in universities throughout Jianghai City."

"Yes." The criminal police at the scene responded immediately.

"I understand that such a workload is very heavy, but now we can only use the most stupid method." Xia Yan said in a deep voice.

"Understood." None of the detectives were fools, and they understood that there was basically no breakthrough in the case. Even if it was the most stupid method, at least there was still a little way at the moment. We were not afraid of the stupid and tiring method, but we were afraid that it would not work in the end.

"Zhou Zheng, do you have anything else to say?"

Suddenly, Xia Yan looked at Zhou Zheng again. After the case of Wang Fan and Zhao Zhigang, he was very confident in Zhou Zheng's sensitive judgment, so he still wanted to seek Zhou Zheng's opinion before acting.

"I really have no way to provide more information about the victim, but I can draw a little portrait of the murderer." Zhou Zheng's expression was serious, and the appearance of the scene kept flashing back in his mind.

"Oh?!"

Xia Yan's eyes suddenly brightened. The essence of handling a case is to catch the murderer. He is now eager to find out the identity of the victim, and he also wants to use the victim to investigate the murderer.

But it would be great if they could have information about the murderer directly, allowing them to investigate the murderer while investigating the victim, greatly reducing time consumption.

"Tell me quickly!"

There was a touch of impatience in Xia Yan's tone.

Not only him, but everyone right now is waiting for the moment when what they need most is someone who can deliver leads when they reach a dead end in their investigation.

"The murderer, male, aged between 20 and 35 years old, physically strong, clean in appearance, neatly dressed, has certain obsessive-compulsive disorder or cleanliness, strong hands-on ability, withdrawn, or somewhat lonely, unmarried, probably has no girlfriend ..."

When Zhou was talking, his eyes were looking forward, but his eyes did not have a clear focus. His attention was focused on the scene in the piano room.

"The deceased died of mechanical suffocation, and there was no obvious trauma to the brain, indicating that the deceased probably died under the restraint of the murderer. The murderer can easily control the deceased, and the model can be taken to the third floor where there is no Being seen by others means that the body is stronger and more powerful.”

"Strictly speaking, the piano room is not a scene of throwing corpses, but more like a stage for the murderer to show off his works. This mannequin playing the piano is his masterpiece. Judging from the layout of the scene, the murderer is very patient and has hands-on skills. Very strong."

"The murderer has the ability to design the scene and execute it, which means he has plenty of free time, especially the time and space to dismember the corpse, which is difficult for a married person with a girlfriend to do."

"Judging from the expression of the deceased's makeup, the murderer is a relatively pessimistic person. His smile is just a disguise for the outside world. His life may not be as happy as he appears. He will disguise his appearance cleanly and decently, looking It will be very polite."

"This is a scene with a strong sense of ritual. The purpose of the murderer is not to throw the corpse, but to expose the corpse. He deliberately displayed the corpse in front of people, as if publishing his own work, so I think his heart is very I am lonely and hope to be recognized by more people.”

Zhou Zheng's brain was thinking very fast. He was afraid that people at the scene would disturb his thoughts by asking questions if they didn't understand, so he simply explained it during the portrait.

"He knows Jianghai Normal University very well. It is very likely that he is a student here, or has graduated from here, or has the conditions to come and go here frequently."

"This can be seen from the selection of the piano room."

"If you don't know much about this place, you may not even know that there is a piano room here."

"Moreover, the murderer is so aware of the location of the camera here, it doesn't seem like a simple stepping in advance."

"The piano room, or the teaching building of the art department, or Jianghai Normal University, this place will provide the murderer with a sense of security deep in his heart."

The brilliance in Zhou Zheng's eyes became bright and shining. When he said these words, the criminal policemen in the criminal police office also quickly recorded them in their notebooks.

"He is very likely to play the piano, and he is an art major, but he may not like playing the piano, just like the emotions he expressed through the face of the deceased, he is good at concealing his emotions."

"His family is in a good situation, with a house and a car, but he should be living alone now, and he has a separate space that belongs to him, which can be used to dispose of the corpse."

"He should be a soft-spoken but irritable person with a certain aggressive mentality, flexible mind and clear thinking. He will be a clever person on weekdays."

"The active exposure of the dead body is not only for showing off, but also for provocation."

"Who is he provoking?"

When Zhou Zheng analyzed this point, more question marks appeared in his head. These special phenomena at the scene have strong personal psychological marks, and it is relatively easy to analyze the murderer's psychology.

"Gone?"

Xia Yan was a little dazed at the end when he heard it. The case that seemed hopeless at first seemed to become much clearer after Zhou Zheng's portrait of criminal psychology.

"I can only see so much at the moment." Zhou Zheng nodded. He was also trying to analyze it, but lacked more information to support it.

"Zhou Zheng, you have evolved. You didn't draw much information about Zhao Zhigang's case. This case is so difficult, but you can still see so much!" Xia Yan praised.

"The more you do, the more mistakes you make. The murderer's carefully designed scenes just exposed his true thoughts in his heart." Zhou Zheng said seriously: "In your opinion, this case is more complicated than the case of Zhao Zhiyong's murder, but from From the perspective of criminal psychology, more information is given.”

"I probably understand." Xia Yan nodded, thinking silently in his heart.

The simpler the case, the easier it is to find evidence to determine the murderer. Such cases often have little room for criminal psychology.

However, corresponding to this, the more complicated and confusing the case, the more thoughtful the murderer had to spend when arranging it, and the easier it was to expose his instinctive psychological state.

"Right, one more thing."

Zhou Zheng suddenly widened his eyes, his pupils shrank slightly, and said: "The murderer's behavior is like an artist showing his own work, so after his work comes out, he should want to see the feedback of the work, so he should pay attention to it. The response caused by the case, and it is very likely that the work will be shown to the world again!"

"You mean..." Xia Yan's complexion became ugly, and he said under his throat, "The murderer will still kill?"
