Department of Psychology Forensic

Chapter 16 Surveillance Video
As soon as these words came out, everyone in the room looked at Zhao Lei's phone, even Zhou Zheng did the same.

Zhou Zheng frowned tightly. He hadn't seen the surveillance video yet, but this incident alone made him feel that the case seemed more complicated than he had imagined.

Immediately, Zhao Lei picked up his phone and played the surveillance video he just received.

There is also a time display in the lower right corner of the video.

The screen starts at 5:1 on May 22. A red Porsche 32 drove into the underground parking lot of Changhuwan Community. The driver did not get off the car immediately after parking.

The monitoring screen is not so clear, and the faint light flickering inside can be faintly seen from the windshield.

"it's him!"

Zhao Lei pointed to the corner of the monitoring screen, and he could see a man wearing a black leather jacket and jeans, with a peaked cap on his head, and a baseball bat in his right hand, walking back and forth.

"This person is very suspicious!" Xia Yan stared at the figure pacing back and forth like a falcon, and said, "In the video, we can't see his eyes, but I can be sure of his moving posture. Keeping an eye on that Porsche, this person has a certain sense of prevention, but his ability is limited after all, exactly the same as the robbers who have been caught in the past.

Zhou Zheng stared at the video screen silently, didn't speak, and didn't know what he was thinking.

The video screen continues.

Time seemed to be trapped in reincarnation. The red Porsche 911 remained silent. If it weren't for the flickering lights and shadows that could be seen through the windshield, one would have thought there was no one inside.

"Zhao Zhiyong stayed in the car for so long!" Xia Yan muttered helplessly, when the door opened, it was already 22:39, and Zhao Zhiyong stayed in the car for a full 7 minutes.

After Zhao Zhiyong got out of the car, it immediately affected the nerves of everyone in the room. Everyone knew very well that this was the penultimate video of Zhao Zhiyong before his death. The last video was the surveillance video in the elevator, and nothing was wrong. .

As Zhao Zhiyong left the car and walked towards the elevator entrance of Building 2, the dodging figure also followed.

Screen so far.

The end time is 22:41.

It happened to be the time when Zhao Zhiyong entered the elevator monitoring screen.

"This person is suspected of committing a major crime!"

Xia Yan stood up suddenly, his voice was loud, like a shark smelling blood, his whole body became excited, after all, this was an important clue.

"From the last surveillance footage, it can be confirmed that this person followed Zhao Zhiyong, but he did not appear in the surveillance footage. He should have climbed the 17th floor from the fire exit. This is somewhat different from our judgment. If it wasn't for the support provided by the monitoring screen, things wouldn't be so easy." Xia Yan said excitedly: "Zhao Lei, now you bring the surveillance video to the information department and ask them to analyze the person's height and body data. There are already clues, and it seems that the case will be solved soon!"

"Yes!" Zhao Lei immediately got up and ran outside.

"Zhou Zheng, what do you think?" Xia Yan turned to look at Zhou Zheng.

"It's hard to tell now..." Zhou Zheng shook his head, the appearance of the surveillance video disrupted his speculation, and said: "Let's collect evidence first, I have some ideas in my mind, but the evidence can't prove it, and it's a bit contradictory , no matter how the reasoning is, it is not as solid as the evidence.”

"Then..." Xia Yan thought for a moment, then said, "Let's continue the investigation first?"

"Well, I also need to rearrange my thoughts." Zhou Zheng nodded.

"Okay, let's do this first." Xia Yan clapped his hands, attracted the serious attention of the scene, and said: "Now we have a new direction, you summarize all the materials of Ding Hao and Wang Wenxin, and then follow Compared with that figure, if I guessed correctly, it is one of these two people."

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

"Captain Xia, I'm going back first. I'll meet you in the afternoon." Zhou Zheng got up and left the criminal police office.

For a while, the criminal police team watched Zhou Zheng leave without saying anything, but they understood that Zhou Zheng did not go so smoothly this time, and it seemed that such magical moments did not happen every time.

……

After Zhou Zheng returned to the forensic center, he sat on a chair outside the dissecting room, which was reserved for the victim's family.

According to the process, a family member of the victim can watch each autopsy, but few people can withstand the bloody scene, so most of the family members present will sit on chairs outside the dissection room and wait.

"It doesn't make sense!"

Zhou Zheng rubbed his temples with both hands, his brain was running fast. Before that surveillance video appeared, he was still very confident in his inference, but that surveillance video negated his previous inference, and he couldn't help but think He said to himself, "Is it really just a coincidence?"

"No, no, no, there is a problem here..." Zhou Zheng's brain was working quickly, and the evidence he collected was constantly emerging from his brain.

The bloodstains during the on-site inspection, the injuries during the autopsy, the victim's social relationship, and the surveillance video that was abrupt to reasoning.

Zhou Zheng was thinking quickly, piecing together these fragmentary information into a complete picture, which kept flashing back in his brain.

"Zhou Zheng, why are you sitting here? You have something on your mind!" At this moment, Cui Jun's voice sounded, and he sat beside Zhou Zheng. Seeing a gentle smile, "Is it the excitement from the dissection just now?"

"Master, how many people do you think are the murderers?" Zhou Zheng asked suddenly.

"Why do you ask that?" Cui Jun was stunned for a moment, but he didn't expect that Zhou Zheng was not stimulated by the autopsy, but was thinking about the case in his heart.

"I just want to hear your opinion." Zhou Zheng pursed his lips and said.

"Actually, you have an answer in your heart, and my answer is the same as yours." Cui Jun replied with a smile.

"However, there are some other situations that make me not so confident in my judgment." Zhou Zheng said in a deep voice.

"You're just too nervous. This kind of thing won't trouble you. Bureau Qin told me about you. I didn't expect that chicken-eating monster Wang Fan to be drawn by you. Even when I knew that thing was drawn by that After I ate the guy, I felt a chill, and you can think of such a strange possibility, which shows that your talent is extraordinary." Cui Jun comforted.

"However, I did not participate in Wang Fan's case. All I saw were the details investigated by the excellent members of the criminal police team, and the special features marked by you during the autopsy, Master, that is, the skin preparation. My murderer may not use it for other purposes." Zhou Zheng frowned, sighed and said: "Now I am following this case personally, and when I summed up these materials and information by myself, I realized how difficult it is, and there are too many factors. I can't figure it out."

"Zhou Zheng, you can be affected because you think too much, and I didn't find the murderer's problem because I didn't think too much. When making a report, things like skin preparation can be done. As subtle as possible, this is what forensic workers should do, and they should not leave any details, because they may become clues to solve the case, but..." Cui Jun changed the subject and said: "From the perspective of criminal investigation, whether it is traditional criminal investigation based on evidence or psychological profiling based on behavior, what you have to do is analyze the effective details, not all the details. Filter and eliminate the interference items inside."

"Interfering items..." Zhou Zheng was thoughtful. In the past, when he was exercising criminal psychology, it was like doing a question. There would be information on the question stem, and the answer could be made based on this information. In reality, there may not be such a wealth of information, and some information may not be useful.

"This is the same as our forensic doctor's autopsy to determine the cause of death. If we want to find the ultimate truth, we need to eliminate other interference items. Let me just give you an example. traces of arsenic, do you think that the cause of his death was poisoning?" Cui Jun asked.

"No." Zhou Zheng shook his head and said, "A small amount of arsenic has been taken in the body many times, and the course of the disease can last for several years. If Zhao Zhiyong's blood contains a small amount of arsenic, it can only prove that he has taken poison or someone injected him. Poison, but it didn't affect the cause of his death." Zhou Zheng's eyes suddenly widened at the end of his speech, and the eyes flashed fiercely.

"It seems that you have figured it out." Cui Jun patted Zhou Zheng's shoulder and said, "When I was young, I also liked to investigate cases with criminal policemen. The belief in bringing the murderer to justice with my own hands, I have encountered your problem before, because when we collect clues, we will try to collect as many clues as possible, but some clues are not very important for investigating the case. It’s not helpful, it’s just distractions, and you have to block those distractions.”

"Master, I understand, thank you!" Zhou Zheng suddenly realized.

"After the detailed autopsy of Zhao Zhiyong's case, what happened at the murder scene can be restored. This is the last words of the deceased passed on to us through the corpse. The forensic doctor's inference on the restoration of the scene should avoid being affected by interference items, especially some information may be what the murderer wants us to see." Cui Junyu shared his experience over the years with great earnestness.

"I understand!"

Zhou Zheng nodded continuously. He realized his problem, which is also a problem that many fresh graduates often encounter when they are employed. The transformation of theoretical knowledge and practical experience, the knowledge he has learned in the past stays at the theoretical level. When you are in the middle of a case, it is easy to be confused by the authorities.

This is like a student who has appreciated the works of many artists. He has clearly studied the artist's methods and characteristics, and is at the stage of gaining confidence in knowledge. However, when it is his turn to create art, he will encounter difficulties one after another. Instead, prone to self-doubt.

"Zhou Zheng, you are a student of Fan Guoliang. You want to learn his calmness. Now that you have figured it out, can you draw the portrait of this criminal suspect?" Cui Jun's eyes flickered with curiosity, and he came here The original intention was not to comfort Zhou Zheng, but just happened to catch up with Zhou Zheng's emotional problems. He wanted to ask about Zhou Zheng's portrait and witness the magical criminal psychology for himself.

"The existing intelligence samples are a bit small, but some can still be drawn." Zhou Zheng nodded, and said: "The murderer, male, has a strong physique, is over 180 tall, knows the victim, and has a very deep hatred. Wan District is very familiar, the place of residence is not too far away, there should be a car, this is a premeditated murder, and it should be the first time the murderer commits the crime, if he is not caught, it is likely that he will not commit another crime in the future. "

"That's all?" Cui Jun couldn't get enough of what he heard.

"There are too few intelligence samples, there is only one case, and there is no way to find the characteristics of the murderer from the specific rules in it, but the characteristics of this case are also very clear, that is, vendetta. There is no need to endure these three psychological stages anymore. When they kill people, they have already satisfied their desire for revenge, and vent their emotions to the corpse, and they will get great satisfaction in their hearts." Zhou Zheng said: "The portrait of criminal psychology belongs to the sample. The more people there are, the easier it is to find connections, and it is more suitable for complex serial murder cases. The murderer in this case may not continue to commit crimes in the future, so it is still necessary to investigate from the social relationship of the victim Zhao Zhiyong. Being able to kill so cruelly must not be simple hatred. There should not be many people who hate Zhao Zhiyong like this."

"Your direction is right, let's continue like this, go to the criminal police team for a meeting in the afternoon, it can be considered that our forensic center has participated in solving the case." Cui Jun said with a smile.

"Master, why don't you help solve the case?" Zhou Zheng asked curiously. He learned from Cui Jun's words that the latter also worked with the criminal police team to solve the case.

"It happened a long time ago. Some accidents happened. It's not important to mention it." Cui Jun waved his hand, saying that he didn't care, but some unnatural changes occurred between the eyebrows exposed outside the mask .

"I see."

Zhou Zheng immediately heard that there was a story about Cui Jun, but the latter obviously didn't want to talk about it at this time, so he stopped asking, lest it backfired and annoyed people.

"Master, I will go to the criminal police team again. This time I want to see the surveillance video of the elevator for myself. I still don't think the murderer will climb up to 17 flights of stairs before killing the man. Maybe there is something missing."
