Department of Psychology Forensic

Chapter 36 The murderer is on the scene!

"very possible!"

Zhou Zheng nodded his head heavily, his brows furrowed tighter and tighter, and he said: "Judging from the scene that the murderer spent a lot of time arranging, there are extremely strong personal emotions. I can't tell what kind of emotions it is yet, but I I can feel that he may not have vented yet."

"Emotions..." Xia Yan also fell into thinking.

"That's right, it's emotions, and that face after makeup represents similar emotions!" Zhou Zheng said in a deep voice: "From the theory of criminal psychology, no one is born a criminal, nor will he be a criminal in a certain place." Suddenly becoming a criminal at a certain point in time, the incentives for criminal behavior are often accumulated over a long period of time, that is to say, it takes a period of time to ferment from planting the seeds of crime to growing into a real crime."

"I understand what you mean." Xia Yan nodded and said, "You want to say that the murderer's emotions didn't arise suddenly, but existed a long time ago, accumulated over time until now, so his emotions are not like this A case can be vented, right!"

"Yes, that's what it means. Moreover, he must have been stimulated by something recently. That incident may not be a big one. It was just a fuse that completely ignited his accumulated emotions for so many years and led him to embark on the road of crime. " Zhou Zheng said in a deep voice.

"Do you think the murderer and the victim knew each other?" Xia Yan suddenly asked a very crucial question. He stared straight at Zhou Zheng, his eyes flickering with thought.

"Not sure." Zhou Zheng shook his head and said: "If it is inferred from a conventional point of view, the murderer can throw the head of the deceased, which shows that he does not care about the victim's identity being exposed, which greatly reduces the possibility of acquaintances committing the crime. The murderer has serious psychological problems and is extremely prone to perversion, so it is not impossible to do something that is not within the scope of normal people's understanding, but within his own unique logic."

"I understand. For the time being, we cannot rule out the suspicion of an acquaintance committing the crime. We have to prepare with both hands to investigate." Xia Yan's face was extremely serious.

"I'm sorry, I can't help you much." Zhou Zheng said with his lips pursed. He knew very well that there is still too little information to provide in this case. The criminal police who want to screen the murderer is like looking for a needle in a haystack. is too big.

"What are you talking about? Sorry, if you hadn't provided us with the portrait, we would still have no idea at all. Now the scope has been narrowed down a lot, and after your analysis, we have a general understanding of the murderer. .” Xia Yan forced a friendly smile.

"Then I won't hinder you from handling the case. If you have any clues, remember to tell me. I'll think about contacting you right away." Zhou Zheng said seriously.

"Don't worry, you are our great strategist. As long as I find something, I will tell you as soon as possible, and we will keep in touch." When Xia Yan spoke, he immediately got up, clapped his hands to attract everyone's attention, and said: " You have also heard what Zhou Zheng said, and now we are investigating from two aspects at the same time, while investigating the suspect who fits the characteristics of the murderer, and investigating the disappearance of female students in various universities in this city."

"Yes." The detectives on the scene nodded immediately.

"Master, I'm a little puzzled." Zhao Lei suddenly raised his hand and said, "Now we can only confirm that the deceased is a young woman, but she may not be a female college student!"

"Zhao Lei, we have limited manpower. The scene arranged by the murderer is inside Jianghai Normal University, which has caused extremely bad influence. Now public opinion in society has begun to ferment, and various opinions are flying everywhere on the Internet. We must prioritize the investigation of female college students. Make sure the deceased is a female college student." Xia Yan explained.

"Then what if it's not?" Zhao Lei continued to ask.

"If we can confirm that the deceased was not a female college student, and confirm that no female college students in the city have any problems, then we can at least give an explanation to the society first, and try to reduce the panic of college students as much as possible before doing the next investigation." Xia Yan explained relatively patiently: "In short, this matter must be carried out with priority!"

"Understood!" Zhao Lei responded immediately.

"Everyone work harder from now on. Before 18 o'clock in the evening, we must have a phased conclusion." Xia Yan picked up the notebook in his hand, and led the criminal police team to walk through the office first.

After the criminal policemen in the criminal police team left one after another, Zhou Zheng was the only one left in the office.

"You people really don't treat me as an outsider."

Zhou Zheng walked out towards the door and closed the door when he left. During the two days of short internship here, his contact with the criminal police team gave him a new understanding of the criminal police.

In the past, even though he was a forensic major, he had learned a lot of relevant knowledge, and he also dabbled in traditional forensic science when he was studying criminal psychology, but all of that was ultimately reflected in theory.

Before coming here, he was just a student. Solving a case is like a question on a test paper. He only needs to fill in the answers.

But it's different now. After he personally inspected the scene, dissected the victim, met the murderer, and felt the complete crime, after these things, he felt more and more the sense of sacred mission derived from his profession.

Words for the dead, rights for the living.

Such words are like slogans before they are actually in this position, but only after witnessing the tragic appearance of the victim and judging what happened to the victim during the autopsy, the restless heart is hidden under the peaceful appearance .

Before he knew it, even Zhou Zheng didn't realize how he made it all the way. He had already returned to the forensic center and sat at his workstation.

His eyes were focused on the computer screen, looking at the photos of the scene repeatedly, feeling the sense of ceremony at the scene.

Gradually, time passed by every minute and every second, Zhou Zheng stared at the photos that kept turning over on the screen as if in a daze.

I don't know how many times these photos have been turned over.

Suddenly, he thought of something, picked up his phone, searched through WeChat, and found Wang Suanlian's profile picture.

【Is it ok to accept phone call? 】Zhou Zheng immediately sent a message.

【convenient】

Almost instant response, like living on WeChat.

Immediately, Zhou Zheng picked up the phone, pressed the voice call, and was connected just after it rang.

"Sour, I have some things that I need to ask you. I know this may be cruel to you. I hope you can give the exact answer as much as possible. If you are not sure, just say that you don't know." Zhou Zheng said quickly Said.

"Well, you can ask." Wang's sour tone was quite gentle, with a hint of shyness.

"I took a rough look at the transcript. You and Sun Xiaoqing were in the studio on the fourth floor this morning. Why did you go to the piano room on the third floor?" Zhou Zheng added after asking, "I know you are It’s said in the transcript, I just want to hear from you.”

"Well, in the morning, I asked Sun Xiaoqing to go to the studio to paint, because I want to paint when I am nervous, and painting can calm my heart. When we were about to leave, I just heard Lou The song "To Alice" sounded inside." Wang Suansu explained.

"Nervous? What made you nervous?" Zhou Zheng keenly caught the special place.

"Is this okay to say?" Wang's sour tone became even more shy.

"I'm not interrogating you, I'm just asking casually, you don't have to answer if it's inconvenient for you." Zhou Zheng immediately realized that the question was a bit off track, and it had nothing to do with the discovery of the body itself.

"It's okay, didn't I ask for your WeChat number? I'm going to send you a friend application, but I'm not sure if you'll pass it, so I'm nervous and want to draw..." Wang Suansuan's final voice became more and more serious. Small.

"Why are you nervous about applying for a friend from me? I'm not a bad person!" Zhou Zheng frowned slightly.

"People didn't say you were a bad person..." Wang's sour voice was as thin as a mosquito.

"Don't ask this, sour, I mainly want to ask you, are you sure what you heard is the piano music, not the sound from other equipment?" Zhou Zheng asked seriously.

"You...don't be like this...I'm scared!" Wang Suansuan thought of that song, and goose bumps couldn't help but appear on his body.

"It's okay, don't think about it, just pretend I didn't ask." Zhou Zhengneng could hear the panic in Wang Suansuan's tone, thinking that the latter had just experienced such a thing, it is indeed a bit cruel to ask now.

"Actually...it may not be the sound of the piano..." After Wang Suanan thought for a while, he said, "I just heard the song "To Alice", and it came from the direction of the piano room on the third floor, because At that time, Sun Xiaoqing told me a ghost story, and the place was still in the piano room, which made me subconsciously think it was a piano piece, but now that I recall it, it doesn’t quite look like it.”

"Then what do you think it looks like?" Zhou Zheng asked immediately.

"The phone ringtone, yes, it's a bit like a phone ringtone." Wang Suansu replied in surprise.

"Sure enough." Zhou Zheng nodded, his eyes flashed, and he asked, "When you were in the studio on the fourth floor, did you see any suspicious people, such as people walking in and out of the corridor?"

"I didn't pay attention!" Wang Suansu recalled: "At that time, my attention was all on my mobile phone and Huahua. There may be no one in the corridor. If there is someone, I can't be unaware of it!"

"Did you encounter any suspicious people when you came out of the studio to the piano room?" Zhou Zheng asked again.

"I'm so scared as you said." Wang Suan's voice became more and more frightened, and he said, "There should be no one. It's quite bright, and I don't see any figures!"

"Okay, that's all." Zhou Zheng stopped asking, and said, "Sour, thank you, the information you provided is very helpful. After I finish handling this case, I will treat you to dinner."

"No, it's okay, I can ask you." Wang's sour tone returned from fear to shyness.

"That's it for now. I still need to do some research here, so hang up." Zhou Zheng hung up the call directly.

Immediately afterwards, he dialed Xia Yan's cell phone number.

"Captain Xia, I know how the corpse plays the piano." After the call was connected, Zhou Zheng spoke first.

"Why didn't you scare me to death!" Xia Yan said angrily.

"Mobile phone! The murderer used a mobile phone! Captain Xia, do you still remember that there is a mobile phone with a sufficient battery and a SIM card in the physical evidence department. Feng Yu said that it was found in the piano. If I guessed correctly, the ringtone of the mobile phone is "" To Alice." Zhou Zheng ignored Xia Yan's complaints and hurriedly reported.

"This is a way..." After thinking for a while, Xia Yan said, "Who called then?"

"The murderer did it!" Zhou Zheng said, "He just wanted the scene he arranged to be discovered."

"It makes sense to say that, but how can he be sure that someone will go to the scene?" Xia Yan asked in confusion, then his tone changed, and he said coldly: "You mean... the murderer is at the scene!"

"That's right." Zhou Zheng nodded and said, "After we discovered this mobile phone, we never called again, which means that the murderer already knew that we had discovered the scene, so there is no need for the mobile phone to ring again. .”

"This is indeed a major discovery. I will urge the Physical Evidence Section to crack the phone as soon as possible, and then contact the telecommunications company to investigate the call records of the SIM card." Xia Yan said.

"Actually, we have an easier way to be sure immediately, that is to change the SIM card of anyone to that mobile phone, then dial his number, and test whether the ringtone of the mobile phone is that Beethoven's "To You". Alice." Zhou Zheng said eagerly.

"This is indeed a method. Let's go to Feng Yu to test it out. I'm going to check it out. I'm afraid it will be very late when I go back." Xia Yan said after thinking.

"Okay, I'll go talk to Feng Yu first, and I'll tell you the result when you come back." Zhou Zheng nodded.

"OK, that's it for now." Xia Yan hung up the phone.

……

Jianghai City Bureau, Trace Inspection Division.

When Zhou Zheng arrived here, everyone was busy. The office here was completely high-tech, with all kinds of instruments and equipment everywhere.

"Zhou Zheng, you're here. Xia Yan greeted me. We just got ready, so come with me." Feng Yu greeted Zhou Zheng who was at the door, but after walking a certain distance, he stopped and said goodbye to each other. Keep your distance.

"I'm sorry to trouble you." Zhou Zheng said in a deep voice.

"It should be." Feng Yu didn't say much, and led the way directly into the office.

At this moment, several people were surrounding a table, one of them was wearing white gloves, put the SIM card into the card slot, then inserted it into the mobile phone, and then nodded to the colleague next to him.

The colleague picked up his cell phone and made a call.

After a short delay, the screen of the mobile phone on the table lit up, accompanied by a very loud ringtone.

"Tick tock tick tock tick tock..."
