Criminal Investigation Notes

The old site of Huadu Middle School at 6 o'clock in the evening, the sun is setting in the west.

A team of forensic and forensic personnel came to a walnut forest in the back. The walnut forest was lush with lush vegetation.

This walnut forest is neither big nor small.

After Huadu Middle School was relocated, few people came here.

Xing Jing carried the test box and asked Shang Qinghan who was standing beside her worriedly: "Director Shang, where did Bureau Tan get the tip?"

Shang Qinghan is the director of the forensic examination room of the Huadu General Bureau. He is 35 years old this year. He has already read thousands of corpses, and he is calm. He looked at the surrounding environment indifferently and said: "The order directly issued by the Tan Bureau should be There's a reason for that."

Xing Jing frowned slightly. She felt that the order she received today was a bit vague. She received a report that there might be a female corpse buried in this walnut forest. As for who this female corpse belonged to, when was it killed, and where was it buried? No one knows who reported it.

But it was such a simple order, but Bureau Tan asked them to investigate carefully. Director Shang became serious after answering a few phone calls, and then asked all of them to put down their work, except for those who were out on duty. Everyone brought it here.

Under such circumstances, Xing Jing was even more curious about the source of this news. She tentatively asked while wearing gloves, "Can we gain anything today?"

Shang Qing said coldly: "Then we will find out after checking."

More than 20 people began to search inward from the periphery of the walnut forest.

As long as someone has been there, there will be traces left.

Even if the time spans months, or even years, there will still be some clues left.

Footprints stepped on, scratches on the ground, dripping blood... all these clues can't hide from the eyes of professional books.

Soon someone found something in the west of the walnut forest, and said through the walkie-talkie: "Director Shang! The plants here have been crushed."

Shang Qinghan hurriedly walked over. In that area, the direction of plant growth was a bit strange, the ground plants would chase the light, and the branches and leaves of the plants in that area were dumped in one direction, and then turned a corner due to the sunlight. towards the sun.

This is obviously a trace formed after being dragged by a heavy object.

Those plants didn't die because of the drag, but because the crushing changed the direction of their growth.

After Shang Qinghan's identification, he asked a few physical evidences to take pictures here, and then dispatched the others: "Follow the direction of the traces, and focus on searching."

Soon, they found a trace of soil being turned over not far ahead.

Although that place has already been carefully filled in, and the nearby footprints have been erased, it can still be seen that it is different from other places.

"It should be here!" Shang Qinghan made a decision, "You should take pictures immediately, save the evidence, and then dig."

More than a dozen physical records and forensic doctors have been busy, pulling up the blockade, and everything is proceeding in an orderly manner.

Xing Jing couldn't imagine that something was really buried under the forest.

There were male colleagues, and the girls didn't have to do it themselves, and soon someone dug up the land with buried traces.

Twenty centimeters, fifty centimeters... As the digging got deeper and deeper, the traces of the burial became more and more obvious, but it was only after more than one meter of digging that there was still no trace of the body.

The sun gradually went down and the temperature dropped, Shang Qinghan's expression became more and more serious.

Wu Jian He Wei has always done a lot of research on soil. Looking at the soil dug nearby, he said, "Such a deep pit was formed after being dug several times."

Xing Jing leaned down, fearing that someone would have to dig deeper: "The murderer is really patient..." She had worked for so many years, but this was the first time she had seen such a deep burial.

Shang Qinghan said, "The murderer doesn't want others to find the body."

When the excavation reached nearly two meters, the smell of rotting corpses poured out, and someone finally said, "The corpse was dug up!"

Two more people went down to the big pit and helped to clear the body out. Xing Jing probed to see that the body was partially boned, but it could be judged from the clothes that the victim was a young woman, and the time of the murder was this spring.

Xing Jing suddenly remembered something by the reflection of the light, she pulled up the mask: "This dress... Could it be that the victim is... Pei Weiwei?"

After saying the name, Xing Jing's voice trembled, and she felt her eyes warm, and then she felt tears rolling in her eyes. As a forensic doctor who has been paying attention to this case, she never thought that Pei Weiwei's body would be dug up today.

The girl who had been missing for more than 100 days was finally found... She couldn't help crying with excitement.

Pei Weiwei, welcome home...

"Pei Weiwei? That long-lost girl, Pei Weiwei?"

"I just watched the interview with her parents the other day."

"It's most likely her. I remember that Pei Weiwei wore such a coat when she disappeared."

"After searching for so long, I finally found it..."

"Was she really killed by Song Rongjiang?"

Everyone's emotions suddenly became excited, and Director Shang said rigorously: "The identity of the victim cannot be completely determined yet. You should transport the body back as soon as possible for autopsy and comparison."

Although he said so, Xing Jing clearly felt it, Director Shang let out a long sigh, and the stone in his heart finally fell to the ground. He urged again: "Xing Jing, look at the scene and I'll report to Bureau Tan."

Xing Jing said yes, and then she looked at the back of Director Shang turning her head to make a phone call, and guessed in her heart that the police had been investigating for so long and found nothing. Where did Bureau Tan get the news?

Is there really someone in this world who can detect the secrets in the hearts of those murderers?

At eight o'clock in the evening, Lu Junchi's car finally got off the highway and stopped outside a hotel.

Before Su Hui hoped to be able to rush back to Huadu that day, so after Lu Junchi completed the handover, the two did not eat dinner and drove back.

Now that it is not far from the Chinese police, Lu Junchi once again offered to invite Su Hui to dinner, but Su Hui did not refuse.

Lu Junchi chose a Cantonese restaurant with good reviews and ordered a few light dishes.

Lu Junchi was hungry, but Su Hui didn't eat much.

Lu Junchi said apologetically, "Mr. Su, is this meal not to your taste?"

Su Hui shook his head, lowered his head and drank water: "The food here is delicious, I've never been a big eater, you don't mind."

Having said that, he coughed a few times.

When Su Hui sat like this, his waist was a little painful again. At this moment of good and bad, he didn't dare to exert force at all.

Lu Junchi was almost done eating, he put down his chopsticks, wiped his hands with a tissue, and then raised his head and said to Su, "No matter what, I have to thank Mr. Su for this case. Without your guidance, the case would not have been like this. Well, it was cracked so quickly."

Su Hui turned his head: "Don't thank me, I just happened to help a little."

In fact, every time he met Lu Junchi during this period of time, there was a certain chance, and he followed a case unknowingly.

Lu Junchi said again: "Mr. Su, there is one thing I don't quite understand. In this case, I feel that you are using some criminal mental derivation, and the accuracy rate is very high, but when you first met, why did you reject it? What about the Criminal Minds profile?"

Su Hui was stunned for a moment, and then explained: "Captain Lu, you misunderstood. I don't reject criminal psychology profiles. I just think that those psychological profiles must be based on the actual case."

When I met Lu Junchi that time, the time was short, and he didn't have time to explain many reasons.

Seeing that Lu Junchi was a little puzzled, Su Hui held a cane and continued to explain: "I personally don't think criminal psychology profilers can sit in the office. Just relying on some photos and documents, it is impossible to draw correct results. With the investigation, As more and more information about the murderer is known, and the information is confirmed to be true, criminal psychology can exist as an auxiliary means."

Su Hui's statement at this time, combined with the example of this case, Lu Junchi somewhat understood.

Whether he started to visit Director Liao or asked Su Hui, he asked them to stand on the periphery of the case to guide them. When he didn't know enough about the criminals, the profiles he got were like those that Director Liao told him. result. Even if there is correct information in it, it is mixed with wrong information and has no practical significance.

Therefore, at that time, Su Hui repeatedly reminded him that the profile results at this time cannot be regarded as the real results, and must be combined with the actual situation.

However, as the case progresses step by step and more and more cases are known, criminal psychology profiling can play a certain role.

Lu Junchi asked again, "Mr. Su, why do you object to the existence of the Action Analysis Team?"

Su Hui's eyelashes blinked, he lowered his head and took a sip of water: "Because at that time, that department had gone astray..."

Lu Junchi couldn't help but wanted to refute him: "You can't say that. After all, that department was the hard work of other people back then, and they did give a lot of useful guidance..."

Su Hui Junxiu's face was expressionless, but his hand clenched the cup unconsciously: "It is this kind of occasional correctness that makes them more unaware of their own problems."

Su Hui was afraid that he didn't understand and gave an example: "In fact, in the history of criminal psychology profiling, there have been many such cases. For example, when the police traced the Green River killer, the profiling analysis gave and The result of the murderer is completely different. The profiler believes that the murderer may smoke, drink alcohol, and may have a criminal record. This analysis results in the grassroots police passing by the murderer many times. This is because the police believe too much and rely on criminal psychology. The consequences of writing."

Having said that, Su Hui seemed to be reluctant to discuss those matters, so he raised his head and changed the subject: "Have your serious crime team encountered many serial killers?"

Lu Jun said lately: "There are always some. You should have heard of the most recent one, the murder driver Song Rongjiang, and the other one is Fu Yunchu."

Su Hui hummed.

He had just met Song Rongjiang today, and later played against Fu Yunchu.

These two people have their own peculiarities, their motives, ways and crux of crimes are different, but at the same time, they have many things in common.

Pretentious, crazy, cruel, in their world, other life is as small as dust...

They are all butchers in this city, raising their butcher knives in the face of innocent women.

No matter Pei Weiwei or Ning Ke, those women who were murdered are living lives, they have parents and families. They shouldn't have been treated like this, they shouldn't have had this outcome.

Lu Junchi continued: "When I first returned to China, I found that many parts of the country rejected the idea of ​​serial killers and were very scared. They are a bit taboo against doctors and hope that such people will never appear, but at the same time, they contradictly hope that the police can quickly arrest them. Arrested."

But in fact, it is inevitable that there will be such people in every country and time.

Every time the police encounter and fight against such a murderer, it is a complicated and difficult process.

Su Hui: "It's normal. It took many years to come into contact with the concept of serial killers in China. People's first reaction to something they don't understand is to deny its existence, as if it doesn't exist if it is denied. Same."

Even criminal psychology has its roots in the West.

The acceptance and research of these theories in China are many years later than those in foreign countries. Today, when he lectures to the students, everyone listens with a curious attitude. It was not until the case of Pei Weiwei that they felt that the vicious murderers lived near them.

They may be in the same city as us, breathing the same air.

Lu Junchi said: "I have also heard that some, such as the neighboring country next door, have always claimed that their country has no serial killers."

Su Hui nodded: "Until the appearance of the chessboard killer."

It was the appearance of chessboard killers that forced the police in neighboring countries to face up to the existence of serial killers.

Because of those wrong concepts, the chessboard killer was only discovered for several years because of his evildoing, and his appearance also slapped those ignorant people in the face.

Lu Junchi said: "I personally think that if the environment is more stable and our police work harder, it will be more peaceful. On the contrary, despair and madness at the bottom will erupt. The law pronounces a sentence, and it is easy to kill a person. But how to trace the source? It's actually harder to understand what happened and find more ways to avoid killing."

People must realize that by studying the psychology of serial murderers and facing them squarely, more innocent lives can be saved.

This is the advancement of modern criminology.
