civil forensic

Chapter 681
The clouds in the sky are bright red.

The gathered dark clouds desperately squeezed their positions, but they could only circle around the edge.

Some dusty dark clouds kept sacrificing themselves and pounced on the red cloud, and then part of them was taken away, and then retreated dejectedly.

Sometimes, some gray clouds will be spit out by the red clouds, and they will float on the edge of the big dark clouds, unable to blend in or escape, and they are weak.

Tao Lu exhaled a big mouthful of smoke, as if he wanted to assist Wu Yun, and his whole body was showing signs of weakness.

Huang Qiangmin was tired from accompanying him, sighed, and said, "Tao Zhi, why don't you go back to the office to rest first, and I'll call you when the results come out?"

"I can't rest well when I go back, so it's better to stay here." Tao Lu is unwilling to leave, he is waiting for the result of Jiang Yuan's selection of cases, if he leaves now, what should Jiang Yuan do after get off work?
Huang Qiangmin remade a cup of tea for Tao Lu, took a sip of water himself, and said, "Jiang Yuan is serious. When he was in Ningtai, do you know how he picked the case?"

"How to choose?" Tao Lu really became interested.

"In order." Huang Qiangmin laughed.

"In order?" Tao Lu didn't understand.

"Just take out a stack of files and solve the case in order." Huang Qiangmin curled his lips and said, "You don't know that at that time, our entire county was running around, and everyone was running around. Arresting people everywhere, the county bureau's procuratorate and If the court is too busy, and some jurisdictions can be changed, send them to Qinghe City and the like, the whole city is busy!"

Tao Lu's eyes were about to shine, what kind of fairy policeman is this!It came out of CCTV.

Huang Qiangmin continued: "Jiang Yuan is serious about selecting cases now, probably because he is afraid that he will not be able to solve a major case, and also afraid that the selected case is not serious enough, so he is a little entangled."

When he said this, Tao Lu not only felt better psychologically, but was even a little grateful—Jiang Yuan was really thinking about himself.

Except for his consideration, who would specifically choose such a serious case.

Solving a case is not a TV series. It is very troublesome to solve a case that cannot be solved. In fact, the current case is a life-long responsibility system. Even if you retire, someone may come to your door with a notebook and ask you about the past. circumstances of the case.And when you think of some important evidence, that's when the assassin is coming.

For ordinary criminal policemen, a murder case is a murder case. It is certainly worth bragging to solve major and serious cases, but those who take the initiative to go to major and serious cases really need a big heart.

In fact, those who can solve ordinary homicide cases are already the elite among the elite.

Tao Lu lit another cigarette, handed another one to Huang Qiangmin, and said with a smile, "Don't worry, take your time, I can wait."

Huang Qiangmin smiled and nodded, and started chatting with Tao Lu again.Soon, Cui Qishan, Xiao Si and Li Jiang, who came to the task force to handle formalities, joined in the chat, and the atmosphere in the smoking area became gloomy again.

The sky gradually darkened.

The lights in the office were dazzling.

When Tao Lu was smoking and getting a little nauseous, he saw a super tall black figure walking out of the office.

Tao Lu immediately poked the cigarette butt deep into the flower pot.

"Tao Zhi." Jiang Yuan shouted politely, and then said: "I picked a case, take a look."

Tao Lu took the file naturally, calmed himself down, and couldn't help but smile. He didn't know where he was, and he was a little worried about gains and losses. A criminal investigation detachment who would make mistakes as long as he did things, and his heart would stop beating when he heard the phone ringing in the middle of the night. Long, whoever wants to do it can do it.

After doing this for a while, Tao Lu looked at the file carefully.

Although it was said that it was a serious case, Tao Lu was shocked by the contents of the dossier: "The case of rotting corpses in the rain?"

As we all know, crimes committed on rainy days are more difficult to investigate.There are several key points here. For example, evidence is easily washed away by rain, and the efficiency of cameras and other equipment will also be reduced. In addition, when it rains, there are relatively fewer pedestrians and poor visibility, making it difficult to find witnesses.

This truth is basically understood by anyone who has studied a little bit of criminology.Cases such as the butcher on a rainy night in Hong Kong were all carried out under the cover of rainy days.

Naturally, there are always some criminals who choose similar methods to commit crimes.But among them, there are actually not many cases that can be accumulated.

"The Case of the Rotting Corpse in the Rain" is one of them.

The victim of the case was found on the side of a deserted path.The path leads to an abandoned quarry. There are no cars or people passing by now. It was the nearby villagers who occasionally passed by and smelled the stench. When they went to look, they discovered the giant body.

After the criminal police team arrived, the first thing they noticed was that the area around the corpse had been carefully cleaned up. Based on the forensic identification of the time of death, it was determined that it was raining during the two days when the corpse was thrown away.

But if that was the case, the case would not be titled "in the rain". Instead, two similar cases were discovered in succession in the next two months.

The body was dumped in the wild, and it was raining around the time of death—the forensic doctors in the capital are strong, so it is no problem to determine the time of death on a certain day.After the identities of the victims were confirmed one after another, there were also similarities: all three were stray warblers traveling with guests.

The sameness of the three cases, combined with the careful cleaning of each body and its surroundings, and the fact that the victims were the serial killer's favorite sex workers, makes the "rain" moment stand out. up.

Knowing how to use the weather and choose vulnerable victims, this kind of obviously professional murderer will naturally receive extra attention.

The actions of the murderer also show that the murder was planned, not impulsive.

It is actually very difficult for a normal person to have three enemies that still need to be killed after careful consideration.

Therefore, this kind of murderer is essentially committing crimes for the sake of killing, not for profit. Such speculation naturally attracted a large amount of police force from the criminal police detachment, especially after the third case occurred. Tao Lu not only dispatched troops, but also Please use foreign aid from ministries and commissions and other places.

But they failed to solve the case.

Fortunately, after the three cases, no similar cases occurred in the next half year, which made Tao Lu and others think that the murderer had disappeared.

However, the fourth case resurfaced just three years ago.It’s the same wandering warbler who accompanies tourists, the same dumping of corpses in the wild, the same dumping of corpses on rainy days and the careful cleaning of crime scenes...

Then, the murderer went into hiding again.

Tao Lu didn't expect Jiang Yuan to choose this case at all, and couldn't help saying: "It's true that the case you chose is a serious case, but it will be too difficult."

He glanced at Huang Qiangmin, didn't you say that Jiang Yuan was picking a serious case that was easy to solve and valuable?How did it become such a difficult case?
Huang Qiangmin could understand Tao Lu's eyes, coughed twice, and first used words to defend: "Let's just say, are there any serious cases in the backlog that are easy to solve? They are all serious cases that have not been solved, and it is not likely Big cases are more difficult than small cases, right..."

"The resources invested in major cases and special cases may be a hundred times, a thousand times that of small cases!" Tao Lu said: "The case of rotting corpses in the rain was also reviewed by heavyweight technical experts from the ministries and commissions. If it is true..."

"How long have the technical experts been watching?" Jiang Yuan didn't ask who it was, and didn't wait for Tao Lu to finish speaking, and interrupted him in a slightly impolite way.

Tao Lu was a little surprised, recalled it for a while, and said: "It must have been more than an hour to read it, and then gave us a technical analysis for more than an hour."

"More than an hour is only enough to read the dossier and photos. If you look at the photos for a longer time, you can only skip through the dossier." Jiang Yuan is too familiar with the working mode of technical experts, because he That's how it works too.For most of the cases that come to you, you can devote more than an hour to it, which is already a great deal of face.

Technical experts give appropriate technical guidance or counseling based on existing conditions, which is similar to a teacher giving lectures to students. The main purpose is to provide inspiration and support, and it is impossible to help you solve the case directly by doing it for you—this service can only be provided by Huang Qiangmin. style.

Therefore, it is better for a technical expert to be his own. Even if it is a lower rank, the work that takes a few hours or a few days to do is not necessarily worse than that of a technical expert.Of course, if you are strong enough and can get guidance from high-level technical experts, the effect will definitely be better.

Jiang Yuan's rank is already high enough, maybe even better than the technical experts Tao Lu found.

However, most people have not been able to clearly understand this point.

Tao Lu hesitated for a while, and then said: "You decide the agreed case, and naturally it's still up to you. That...have you seen something?"

"I still doubt it for the time being, but..." Jiang Yuan held the file, paused, and said, "The third case is likely to be a copycat crime!"

"Imitation? Why..." Tao Lu was shocked, the amount of information in it was too much.

You don’t need to be a serial killer to know that to commit an imitation crime, you must first know the details and methods of the imitation target’s crime. The situation will definitely be announced externally, and the announcement is also something on the big side, and rarely involves details.

So, if the third case was a copycat, how did the killer know the details?

Tao Lu thought about it and was terrified!
Thinking further, if the third case is a copycat crime, what is the fourth case?
Jiang Yuan opened the file directly at this time and said: "Many details of the third case were in place. When I first read it, I didn't immediately notice the difference. However, when I saw the autopsy photos, the two murderers The difference is huge. Although all daggers are used, the weight and shape of the daggers, the state and hardness of the blade are different, and the way the user applies force is even more different. In this way, even if the stabbing position is similar, it can still be stabbed It was identified that the murderer was not alone."

Jiang Yuan's trace tool identification level has reached LV6. When used at a crime scene, one can see what kind of tools and methods were used to create various traces. This skill is currently mainly mastered by trace inspectors. .

In the forensic pathology mastered by forensic doctors, although it is also necessary to infer the tool that caused the injury, this alone is not as good as the identification of trace tools.

In fact, Jiang Yuan's forensic pathology has reached level 4, even in the capital, he can still be called a technical expert.

Tao Lu didn't understand technology, but he could understand what Jiang Yuan said, thought for a while, and asked the last question: "Could it be an accomplice?"

"It's not ruled out, but it's not like it. Moreover, the fourth case used the same murder weapon and method, which is quite special." Jiang Yuan moved his stiff neck and said, "I think this discovery is enough to restart That's the case."

Tao Lu nodded ignorantly, and was shocked.

Huang Qiangmin's mouth couldn't help but reveal a 66.6-degree smile. What he likes to see most now is the captains of criminal police from other cities looking at his Jiangyuan in shock and stupidity.

"As expected of a big city, the cases are more fancy than those in our small county." Huang Qiangmin kept smiling.
