Department of Psychology Forensic

Chapter 37 Reflection on the Ceiling
The ringtone of the mobile phone is set extremely loud, not the maximum volume, more like a modified stereo.

Rao everyone at the scene was mentally prepared, but after hearing such a ringtone, they were still taken aback.

"Fur Elise!"

Zhou Zheng narrowed his eyes slightly, and understood for a while, just as he guessed, the so-called illusion of creating a dead body playing the piano was created by the ringtone of the mobile phone.

"This phone ringtone should be recorded by myself!" Feng Yu frowned and said, "It's not like the downloaded one, it sounds like a piano music recorded and set as a ringtone."

"It should be like this, that's why the effect of confusing the real with the fake has been achieved to a certain extent." Zhou Zheng nodded and said.

"The ringtone of the mobile phone is still a ringtone after all. There is no way to perfectly replace the piano music, so you will find this flaw. I have to say, your kid's sense of smell is really keen." Feng Yu patted Zhou Zheng on the shoulder and said stubbornly: "But , even if you don't find it, our trace inspection can find it."

"That's natural." Zhou Zheng smiled slightly, and said along the way: "This case is still counting on you!"

"You..." Feng Yu laughed as well. He was a little bit competitive just now, and wanted to prove that the trace inspection department was no worse than the forensic department, but Zhou Zheng's answer instantly dispelled these emotions.

"Feng Yu, thank you for today. I need to check the call history of the SIM card. If there is no accident, the last two calls were made by the murderer..."

When Zhou Zheng said this, his face suddenly changed, and he suddenly thought of something.

"I still have something to do, let's go first!"

Zhou Zheng ran away quickly, and the people in the trace inspection department were stunned, not knowing why he was in such a hurry.

Zhou Zheng quickly ran back to the forensic center, returned to his desk, skillfully turned on the phone, and panted heavily from time to time.

"Zhou Zheng, what's wrong with you?" Cui Jun asked suspiciously.

"I remember one detail that needs to be confirmed." Zhou Zheng immediately logged into the backend of the intranet, entered the file of the case, and accurately found the part of the confession.

"Did you find anything?" Cui Jun's curiosity was aroused.

"I'll find out soon." Zhou Zheng opened the records of Wang Suanan and Sun Xiaoqing, his eyes flicked rapidly, and finally fixed on one of the lines, saying, "I found it!"

"What's going on?" Cui Jun stood up from his seat, walked quickly to Zhou Zheng's side, and looked at the screen, his curiosity was completely aroused.

"According to Sun Xiaoqing who found the body, she said that the campus has been haunted recently. Some students from the dance department heard someone playing the piano the night before, and it was the song "To Alice". When I was in the room, I found that there was no one in front of the piano, so there were rumors that a ghost was playing the piano." Zhou Zheng stared at the transcript and said.

"There's nothing wrong with this world!" Cui Jun scoffed at this statement.

"Master, that's not the point!" Zhou Zheng said in a deep voice, "Just now I came back from the Trace Inspection Department, and I have already proved that the sound of the piano came from the ringtone of the mobile phone. If the rumors Sun Xiaoqing heard are true, then at least it proves the truth." The phone was already inside the piano last night."

"I understand what you mean. This way we can be sure that the murderer had a premeditated plan, and maybe the victim was not dead when the plan was made." Cui Jun reacted instantly.

"Not only that, just now when I went to the criminal police team for a meeting, Team Xia said that the murderer entered the teaching building of the Art Department with an umbrella at around 6:[-] in the morning, and sprayed the camera. It's been a day already!" Zhou Zheng's eyes were shining brightly.

"This is really not a small discovery!" Cui Jun knew exactly what this meant.

"When Team Xia and the others come back, I will synchronize the news. In order not to arouse suspicion, the murderer may not have opened an umbrella or used spray when he entered the teaching building yesterday. This set of actions is to separate the mannequins from the deceased. The head was brought in, so there may be images of the murderer on the surveillance video." Zhou Zheng said seriously.

"That's right, this is a major breakthrough, and it may be possible to identify the murderer in one fell swoop!" Cui Jun looked at Zhou Zheng with admiration in his eyes, and then said: "Take a step back, even if you can't confirm the identity of the murderer, You can also narrow down suspicions to those in the video footage."

"That's what I mean." Zhou Zheng nodded and said, "It's a pity that the surveillance video has not been synchronized to the system, otherwise I can use this time to watch it again."

"This kind of thing can't be rushed. If you have the heart, why not take this time to think about it and find out what clues you can find." Cui Jun patted Zhou Zheng on the shoulder and returned to his work position.

"En." Zhou Zheng nodded, and began to re-examine the file. The case is still under preliminary investigation, and the existing information is very scarce, so he can only watch it repeatedly to find the missing places.

……

At 18:[-] in the evening, Jianghai City Bureau, Criminal Police Office.

Zhou Zheng came here early, besides the original criminal police team, there were also people from the trace inspection department, as well as the deputy director Qin Wangde he was familiar with.

Standing next to Qin Wangde was another middle-aged man in a police uniform. This man was nearly 1.9 meters tall, with a muscular body. You could feel his muscles full of power through his clothes. His expression was extremely serious, as if he There is a feeling of not being angry and arrogant.

Director of Jianghai Municipal Bureau, Ma Yan.

Zhou Zheng had seen a photo of Director Ma Yan on the display wall in the corridor of the Municipal Bureau, as well as some of his resume and honors.

"Let me first report on the case of the model puppet dumping."

Xia Yan got up and walked to the side of the small whiteboard, and began to tell the information collected during the previous meeting, and integrated the information from the forensic department and the trace inspection department together.

After he finished introducing all these, he paused for a while and began to get into the topic.

"In the past few hours, we have conducted a blanket investigation in 31 colleges and universities across the city, and found a total of 3 missing female students who could not be contacted."

"Two of them are students of Jianghai Normal University, and the other is a student of Jianghai Medical University."

"Because it is the May Day holiday, students will not be checked by the dormitory administrator if they do not return home at night, so it is very common for female students in each dormitory not to return to the dormitory, which adds a lot to the investigation work Difficulty."

"As of now, these three people are still in a state of being out of contact..."

When Xia Yan said this, he took out three photos and pasted them on the background wall of the small whiteboard.

"Number one, Xu Ruoyang, a third-year student majoring in tourism management at Jianghai Normal University. According to the information provided by her roommate, she claimed to meet her boyfriend during the holidays. She has not contacted her so far, and there has been no response from her mobile phone or social account."

"No. [-], Xie Yushan, a sophomore majoring in geographic information science at Jianghai Normal University. According to the information provided by her roommates and classmates, she also went to see her boyfriend, and she has been disconnected so far."

"No. [-], Han Na, a third-year nursing student at Jianghai Medical University. According to the feedback from her roommate, she is going to see her boyfriend just like the previous two."

"Whether it's their roommates, classmates, friends, or teachers...all have never met their boyfriends, and they don't even know their names. They are very mysterious."

"It's just based on the feedback from No. [-] Xie Yushan's classmate that her boyfriend seems to be very rich and spends a lot of money."

"During the investigation, it was discovered that the three girls all have a common feature, that is, they are relatively strong, not the kind of character that is particularly dependent on others, and their academic performance in school is also very good."

"At present, we have sent the hair tissue extracted from the three-person dormitory to the laboratory for testing. If any of them match the DNA of the head, we will find out the identity of the deceased."

"As for the other two, we will also keep an eye on them."

Xia Yan reported the results of the afternoon's investigation in a rigorous manner. Although only three people were dug out, they were selected from more than 30 college students, and they were the result of racing against time.

"Everyone has worked hard." Ma Yan nodded and said a word of comfort.

"It should." Xia Yan said in a deep voice.

"Do you have anything to add?" Ma Yan asked blankly.

"Yes." Feng Yu got up and walked over. After standing in front of the whiteboard, he looked in Zhou Zheng's direction, exchanged glances with the latter, and nodded silently.

"When we inspected the scene, we found a mobile phone inside the piano, and the ringtone of the mobile phone was the song "To Alice". This is equivalent to confirming a way for the murderer to let the corpse play the piano." Feng Yu explained.

"Yeah." Ma Yan nodded, thinking in his eyes, and asked, "Is there any more?"

"I only found these so far." Feng Yu shook his head.

"I still have some discoveries."

At this moment, Zhou Zheng got up immediately, walked onto the stage quickly, and said, "I will make some additions about the ringtone of the mobile phone."

In an instant, everyone's eyes on the scene were focused on Zhou Zheng, and even Director Ma Yan's eyes were full of interest.

"The murderer used ringtones to attract people to the scene. This is a mentality that he hopes to arrange the scene to be discovered. Then at that time, the murderer should be near the scene."

Zhou Zheng explained his logic as quickly as possible.

"According to Sun Xiaoqing's notes, some dance students heard the piano piece "To Alice" last night. We should conduct an in-depth investigation in this place."

"Who were in the dance class last night?"

"Has anyone ever left?"

"Did they see anyone or anything unusual after they heard the phone ring?"

"In short, if it can be proved that they heard the ringtone of the mobile phone last night, it means that the mobile phone was placed in the piano earlier, and the murderer may have appeared in the surveillance screen when he was laying out the layout."

After Zhou Zheng finished speaking, the audience fell silent, and after a while, whispers broke out in the crowd, all discussing this matter.

"This is a very good angle. The murderer has arrived at the scene in advance and did not destroy the surveillance in advance, so the murderer's figure will be in the surveillance. As long as we investigate one by one, it will be fine. This will greatly shorten the scope of investigation." Ma Yan nodded in praise.

……

Jianghai Normal University.

The evening wind in early summer blows the lonely campus. After what happened during the day, the school has entered into security, and the students have been arranged to return to their dormitories.

After all, if such a thing happened once, it would have an extremely bad impact on the school. Of course, the school didn't want any other accidents to happen again.

At this time, two security guards are walking on the campus. Starting today, they have added the job of patrolling the campus.

"Have you heard that our campus is haunted now!" said one of the security guards.

"Are you kidding? There's nothing wrong with it. It's just people scaring people. The police have already intervened. It won't be long before the case will be solved."

"Didn't you hear about the ghost playing the piano last night? It is said that when the corpse was found today, it was the piano music played by the corpse." The security guard continued.

"You! I advise you to think less about messy things. People are not afraid of crooked shadows. You have no shame in your heart. What ghosts are you afraid of!"

"Old Wang, see if there is light over there!" The security guard suddenly pointed to the No. [-] teaching building in the distance, which is the digital multimedia teaching building, which belongs to the computer major classroom.

"Are you scaring me?"

"No, look, we locked the building almost an hour ago, and I remember turning off the lights over there!" The security guard's face was ugly.

"Well... don't tell me, it seems that there is indeed light."

"Old Wang, tell me, could it be the ghost on our campus!" The security guard's tone became more nervous.

"Where is the ghost? I think someone took advantage of the chaos to steal. If something is lost, it is our responsibility. Let's go and have a look now."

"I'm a little scared!" The security guard didn't want to go.

"You have the guts to be a security guard! If you can't do it, quit your job early and go home to spend time with the kids!"

"No, look, it doesn't look like a light. Why is it bright and dark from time to time, flickering back and forth!" The security guard already regretted mentioning the light, so he just pretended he didn't see it.

"Let's see it!"

The two security guards quickly ran towards the direction of No. [-] teaching building. The night in early summer didn't get dark so fast, and it wasn't so easy to find the light seeping through the windows in the hazy night.

But... now is an extraordinary period, the security guards are relatively concentrated, and the other windows are dark, so that little bit of light stands out.

From a distance, the lights and shadows on the three windows on the fifth floor of No. [-] teaching building are dancing. It looks like some shadow is flickering, but it keeps changing, making it hard to see.

As the two security guards got closer and closer to building No. [-], their angle of looking at the window also changed, becoming an angle of looking up.

From such an angle, the two found to their surprise that the constantly rhythmic light reflected the shadows of the two people.

The shadows of the two people are reflected on the ceiling, flickering in and out of light.
