Chapter 681: Rotting Corpse in the Rain

The clouds on the horizon are bright red.

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

Some gray dark clouds constantly sacrificed themselves to pounce on the red clouds, then lost some of their parts and retreated dejectedly.

Sometimes, some gray clouds would be spit out by the red clouds, floating on the edge of the large dark clouds, unable to blend in, unable to get away, and weak.

Tao Lu exhaled a large puff of smoke, as if he wanted to assist the dark clouds, and his whole body was full of discomfort.

Huang Qiangmin was tired of accompanying him, sighed, and said: "Tao Zhi, why don't you go back to the office to rest first, I will call you when there is a result?"

"I can't rest well if I go back, it's better to stay here." Tao Lu didn't want to leave. He was waiting for the result of Jiang Yuan's case selection. If he left now, what if Jiang Yuan also went off work?

Huang Qiangmin made another cup of tea for Tao Lu, drank two sips of water himself, and then said: "Jiang Yuan is serious. When he was in Ningtai, do you know how he selected cases?"

"How to select?" Tao Lu really became interested. "In order." Huang Qiangmin laughed.

"In order?" Tao Lu was a little confused.

"Just take out a stack of files and solve the cases in order." Huang Qiangmin curled his lips and said: "You don't know that during that period, everyone in our county was running around. Arresting people everywhere, the county procuratorate and the court were too busy, and some of the jurisdictions could be changed, so they were sent to Qinghe City and so on. The whole city was busy!"

Tao Lu's eyes were shining when he heard it. What kind of immortal policeman is this! He must have walked out of CCTV.

Huang Qiangmin continued: "Jiang Yuan is now seriously selecting cases. I guess he is afraid that he can't solve a big case, and he is also afraid that the case he chooses is not serious enough. He is a little entangled."

After he said this, Tao Lu not only felt comfortable, but also a little grateful-Jiang Yuan is really considering himself.

Who else would specially select such a big case except for considering him?

Solving a case is not a TV series. If you can't solve the case after taking it, it will be very troublesome. In fact, now the cases are all lifelong responsibility. Even when you retire, someone may come to your door with a notebook and ask you about the case of the year. And when you think of an important piece of evidence, it is the time when the assassin is about to come.

For ordinary criminal police, a murder case is a murder case. Solving a big case is certainly worth bragging about, but it really takes a big heart to take the initiative to go for a big case.

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

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

Huang Qiangmin smiled and nodded, and started chatting with Tao Lu about love again. Soon, Cui Qishan, Xiao Si and Li Jiang, who came to the special case team to handle the formalities, joined 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 about to vomit from smoking, he saw a super tall black shadow walking out of the office.

Tao Lu immediately poked the cigarette butt deep into the flowerpot.

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

Tao Lu naturally took the file, calmed down, and couldn't help but smile. He was a little worried about gains and losses at this point. A criminal investigation detachment leader who would make mistakes whenever he did something and whose heart would stop beating when he heard the phone ring in the middle of the night, whoever wants to do it can do it.

After doing this for a while, Tao Lu took a closer look at the file.

Although it was a major case, Tao Lu was still shocked by the content of the file: "The case of a rotting corpse in the rain?"

As we all know, crimes committed on rainy days are more difficult to investigate. There are several key points, such as evidence is easily washed away by rain, the efficiency of equipment such as cameras will also be reduced, and in addition, when it rains, there are relatively fewer pedestrians and the vision is poor, so it is not easy to have eyewitnesses.

This principle is basically understood by people who have studied criminology a little. Cases such as the Hong Kong Butcher on a Rainy Night were all carried out under the cover of rainy days.

It is natural that there are always some criminals who think they have a good plan and choose similar methods to commit crimes. But there are not many cases that can survive into the backlog.

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

When the victim of this case was found, he was located on a small road with few people. The path leads to an abandoned quarry. Nowadays, there are few cars and people passing by. It was the villagers nearby who occasionally passed by and smelled the stench. Then they went to see and found the huge corpse.

After the criminal police team arrived, the first thing they noticed was that the area around the corpse had been carefully cleaned. Then, according to the forensic identification of the time of death, it was determined that it was raining on the two days when the body was dumped.

But if it was just that, the case would not be named "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 before and after the time of death - the forensic strength of the capital is strong, and it is completely possible 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 prostitutes who accompanied guests on tours.

The sameness of the three cases, plus the fact that each body and the area around the body were carefully cleaned, and the victims were all sex workers that the serial killer liked the most, made the time point of "raining" stand out.

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

And the murderer's actions also show that his killing is planned, not impulsive.

It is actually difficult for normal people to have three enemies that they still need to kill after careful consideration.

Therefore, this murderer is essentially for killing, not for profit. Such speculation naturally attracted a large number of police forces from the Criminal Police Detachment, especially after the third case occurred. Tao Lu not only deployed troops, but also asked for foreign aid from ministries and commissions and other places.

But none of them could solve the case.

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

However, the fourth case appeared again three years ago. It was also a prostitute who accompanied the guests on a tour, and the body was also dumped in the wild. It was also dumped in the rain and the crime scene was carefully cleaned.

Then, the murderer hid again.

Tao Lu had never thought that Jiang Yuan would choose this case, and couldn't help but say: "It's true that the case you chose is a serious case, but isn't it too difficult?"

His eyes swept to Huang Qiangmin. Didn't you say that Jiang Yuan was choosing a serious case that was easy to solve and valuable? How did it become such a difficult serious case?

Huang Qiangmin understood Tao Lu's eyes, coughed twice, and first used rhetoric to defend: "Let's say, among the serious cases in the backlog, are there any easy to solve? They are all serious cases that have not been solved, and it is not necessarily that big cases are more difficult than small cases, right

"The resources invested in major cases may be a hundred times or a thousand times that of small cases!" Tao Lu said: "The case of the rotting corpse in the rain was also examined by a heavyweight technical expert from the ministry. If it is true..."

"How long did the technical expert examine it?" Jiang Yuan didn't ask who it was, and didn't wait for Tao Lu to finish speaking, and interrupted him slightly impolitely.

Tao Lu recalled with a little surprise, and said: "It took more than an hour in total, and then he gave us more than an hour of technical analysis. ”

“More than an hour is only enough to read the files and photos. If you spend more time looking at the photos, you will have to skip through the files. "Jiang Yuan is too familiar with the working mode of technical experts, because he also works in this way. For most of the cases that come to him, it is considered very respectful to invest more than an hour.

Technical experts give appropriate technical guidance or counseling according to the existing conditions, which is similar to teachers giving students lectures. The main purpose is to inspire and support, and it is impossible for them to help you solve the case directly - this service can only be Huang Qiangmin-style.

Therefore, it is better for technical experts to be from home. Even if they are one level lower, the work they do in a few hours or days is not necessarily worse than that of technical experts. 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 level is already high enough, and may even be better than the technical experts that Tao Lu found.

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

Tao Lu hesitated for a moment, and then said: "It is agreed that the case will be decided by you, so it will naturally be decided by you. Did you see something? "

"I still doubt it for the time being, but" Jiang Yuan took the file, paused, and said: "The third case is most likely a copycat crime!"

"Imitation? How?" Tao Lu was shocked, there was too much information in it.

You don't have to be a serial killer to know that to copycat crimes, you must first know the details and methods of the person being imitated, but China is different from foreign countries. Cases like this serial killer will not necessarily be announced to the public before they are solved, or even after they are solved. The announcement is also some general things, and rarely involves details.

So, if the third case is a copycat crime, how did the murderer know the details?

Tao Lu thought about it carefully and was terrified!

Thinking further, if the third case is a copycat crime, what is the fourth case?

Jiang Yuan directly opened the file at this time and said: "Many details of the third case are in place. When I first saw it, I didn't immediately notice the difference. However, when I saw the autopsy photos, the difference between the two murderers was huge. Although they all used daggers, the weight, shape, blade state and hardness of the daggers are different, and the users' force application methods are even more different. In this way, even if the stabbing positions are similar, it is still possible to distinguish that the murderer is not the same person. "

Jiang Yuan's level of trace tool identification has reached LV6. When used at the crime scene, it can be seen what tools and methods were used to cause various traces. This skill is currently mainly mastered by trace examiners.

Although forensic pathology mastered by forensic doctors also needs to infer the tools that caused the injury, this alone is inferior to trace tool identification.

In fact, Jiang Yuan's forensic pathology has also reached LV4. Even in the capital, he can still be called a technical expert.

Tao Lu doesn't understand technology, but he understands what Jiang Yuan said. After a little thought, he asked the last question: "Could it be an accomplice?"

"It's not ruled out, but it doesn't seem 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 reopen the case. "

Tao Lu nodded in confusion and shock.

Huang Qiangmin couldn't help but smile 6 degrees. What he liked to see most now was the criminal police captains in other cities looking at his own Jiang Yuan with shock and stupidity.

"It's worthy of being a big city. The cases are more fancy than those in our small county." Huang Qiangmin kept smiling.
