Criminal Investigation Notes

At six o'clock in the evening, the former site of Huadu Middle School, the sun was setting.

A team of forensic and physical examination personnel came to a walnut forest behind, where the walnut forest was lush and lush.

This piece of walnut forest is neither big nor small.

After the relocation of Huadu Middle School, there have been few people here.

Xing Jing was carrying the testing box, and asked Shang Qinghan standing next to her worriedly: "Director Shang, where did Bureau Tan get the tip?"

Shang Qinghan is the director of the Law Inspection Office of the Huadu General Administration. He is 35 years old this year. He has already read thousands of corpses. There must be a reason."

Xing Jing frowned slightly. She felt that the order she received today was a bit vague. Why did she receive a tip that there might be a female corpse buried in this walnut forest? No one knows who reported it.

But it happened to be such a simple order, but Bureau Tan asked them to investigate strictly. Director Shang became serious after answering a few phone calls, and then asked all of them to put down their work. Everyone brought them here.

Under such circumstances, Xing Jing was even more curious about the source of the news. While wearing gloves, she asked tentatively, "Can we gain something today?"

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

More than [-] people began to search inward gradually from the periphery of the walnut forest.

As long as someone has been there, it will leave traces.

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

Footprints, scratches on the ground, dripping blood...all these clues cannot escape the eyes of professional biologists.

Soon someone found something on the west side of the walnut forest, and said through the intercom: "Director Shang! The plants here have signs of being crushed."

Shang Qinghan hurried over. In that area, the direction of growth of the plants was a bit weird. The plants on the ground would chase the light, while the branches and leaves of the plants in that area fell in one direction, and then turned a corner because of the sunlight. towards the sun.

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

The plants did not die from being dragged, but because the crushing changed the direction of growth.

After Shang Qinghan's appraisal, he asked several physical evidence to take pictures here, and then dispatched other people: "Everyone follow the direction of the traces and focus on searching."

Soon, they found a trace that the soil had been turned not far ahead.

Even though that place had been carefully filled and the nearby footprints were erased, it was still different from other places.

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

More than a dozen biologists and forensic doctors got busy and set up a blockade, and everything was proceeding in an orderly manner.

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

There are male colleagues, and the girls don't need to do it themselves, someone soon dug up the land with traces of burial.

Twenty centimeters, fifty centimeters... As the excavation got deeper and deeper, the traces of burial became more and more obvious, but there was still no trace of the corpse after digging for more than one meter.

As the sun gradually set and the temperature dropped, Shang Qinghan's expression became more and more serious.

Wujian He Wei has always done a lot of research on soil, looked at the soil dug nearby and said: "Such a deep pit was formed after being dug several times."

Xing Jing leaned down, and if she dug further, she might be as deep as one person: "The murderer is really patient..." After working for so many years, it was the first time she saw such a deep buried corpse.

Shang Qinghan opened his mouth and judged: "The murderer doesn't want others to find the body."

When the excavation reached nearly two meters, the smell of rotting corpses came out, and finally someone said: "We dug up the corpse!"

Two more people went down into the pit and helped to clean up the corpse. Xing Jing probed to see that the corpse was partially ossified, but it could be judged from the clothes that the victim was a young woman who was killed this spring.

Under the illumination of the light, Xing Jing suddenly remembered something, she pulled up the mask: "This dress...could the victim be...Pei Weiwei?"

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

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

Pei Weiwei, welcome home...

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

"I just watched an interview with her parents a few days ago."

"It's probably her. I remember Pei Weiwei was wearing 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 agitated, and Director Shang said strictly: "The identity of the victim is still not completely confirmed. 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 breath, and the stone in his heart finally fell to the ground.He urged again: "Xing Jing, take a 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 his head to make a phone call, and guessed in her heart, the police had investigated for so long before but found nothing, where did Bureau Tan get the news?

In this world, is there really someone who can pry into the secrets of those murderers?

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

Previously, Su Hui hoped to return to Huadu that day, so after Lu Junchi completed the handover, the two of them drove back without having dinner.

Now that the Chinese police were not far away, Lu Junchi once again proposed to invite Su Hui to dinner, and 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, "Ms. Su's food doesn't suit your taste?"

Su Hui shook his head, lowered his head and drank water: "The food here is quite delicious. I don't eat much, so you don't mind."

Having said that, he coughed a few times.

When Su Hui sat like this, he felt a little pain in his waist.This state of good and bad for a while made him dare not use force at all.

Lu Junchi had almost finished eating. He put down his chopsticks, wiped his hands with a paper towel, 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 be as it is. It went well, it was solved so quickly."

Su Hui tilted his head: "You don't need to thank me, I just happened to help a little."

In fact, every time he met Lu Junchi during this period, it was by 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 deduction of criminal psychology, and the accuracy rate is also very high. But when we first met, why did you reject it?" What about criminal mind profiling?"

Su Hui was taken aback, and then explained: "Captain Lu, you have misunderstood. I am not against criminal psychological profiling. I just think that those psychological profiling must be based on the actual facts of the case."

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

Seeing that Lu Junchi was a little confused, Su Hui held his cane and continued to explain: "I personally don't think that a criminal profiler can sit in the office. Only some photos and documents can't get the correct results. And with the investigation, Criminal Minds can exist as an adjunct to the fact that more and more is known about the killer and the intelligence is confirmed to be true."

Su Hui's statement at this time, combined with the examples of this case, made Lu Junchi somewhat understand.

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

So at that time, Su Hui reminded him repeatedly that the profiling results at this time should not be regarded as real results, and must be combined with the actual situation.

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

Lu Junchi asked again: "Mr. Su, why do you oppose the existence of the action analysis team?"

Su Hui's eyelashes flickered, 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's handsome face was expressionless, but his hands clenched the cup unconsciously: "It is this occasional correctness that makes them even less aware of their problems."

Su Hui was afraid that he would not understand and gave an example: "Actually, in the history of the application of criminal psychology profiling, there are many cases like this. For example, when the police traced the Green River killer, the profiling analysis gave and The results of the murderer are completely different. The profiler believes that the murderer may be smoking, drinking, and may have a criminal record. Such analysis results have caused the grassroots police to pass the murderer many times. This is why the police believe too much and rely on the criminal psychology profile Write about the consequences."

Having said that, Su Hui seemed unwilling to discuss those anymore, and raised his head to change the topic: "Do you usually encounter many serial killers in your serious crime team?"

Lu Junchi said: "There are always some. You should have heard of the most recent one, that is the murderous driver Song Rongjiang, and there are others, that is Fu Yunchu."

Su hummed.

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

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

Conceited, crazy, cruel, in their world, other lives are as insignificant as dust...

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

Whether it's Pei Weiwei or Ning Ke, those murdered women are living lives. They have parents and families.They didn't deserve this kind of treatment, and they didn't deserve this kind of result.

Lu Junchi continued: "When I first returned to China, I found that many places in the country were very repulsed by the idea of ​​serial killers, and they were very frightened. They were a little bit taboo, and hoped that such people would never appear, but at the same time, they had the paradoxical hope that the police could quickly arrest them. Arrested and brought to justice."

But in fact, no matter in any country or at any time, it is always inevitable that there will be such people.

Every time the police encounter such a murderer, it is a complicated and difficult process to deal with them.

Su Hui: "This is 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. It's like denying that it really doesn't exist. Same."

Even criminal psychology originated from the West.

The acceptance and research of these theories in China is many years later than that in foreign countries.To this day, when he gave lectures to the students, everyone listened more with a curiosity-seeking attitude. It was not until Pei Weiwei's case that they felt that those vicious murderers were living near them.

They may live in the same city as us and breathe the same air.

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

Su Hui nodded: "Until the Chessboard Killer appears."

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

Because of those erroneous ideas, Chessboard Killer was discovered after several years of evil, and his appearance also severely slapped those ignorant people in the face.

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

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

This is the progress of modern criminology.
