"Oh, I suddenly felt aroused!"

Li Guangnian rubbed Chen Changfeng's neck with a tone of emotion and said, "I killed people on a rainy night. There were three victims one after another. The murderer's methods were cruel and he also had a strong sense of anti-reconnaissance. The bodies found are still in a state of corrupt state. Director Jiang himself has not been able to participate in the first anatomy. Although so... but..."

After all, Chen Changfeng was trained by his own team leader for several years and immediately called out with a conditioned reflex; "Yes, yes, agitation! Emotions became agitation."

"Then you are here to accompany Director Jiang. If you have any necessary things, please help with it. If you need to connect, you can do it quickly." Li Guangnian quickly issued a string of orders.

"Yes." Chen Changfeng habitually took it, without any bargaining.

"Director Jiang, then we will investigate the situation a few days before the victim's death." Li Guangnian smiled and said that he would leave.

"You should pay special attention to the professions of various people around him. Especially those who are exposed to various knives. Well, you should also pay attention to your hobbies." Jiang Yuan reminded.

"I understand. Now some people like to dance with swords and guns, just like some otaku, Gundam can't even understand, so they start buying Frost Sadness. What's the best thing to buy around the Warcraft..." Li Guangnian said a few words, waved his hand and left.

Cui Qishan and others also left one after another.

Chen Changfeng and others left, leaving only himself in the room, Jiang Yuan, Miao Ruixiang, Mu Zhiyang, Wen Ming and a person with so few corpses, whispered: "Our captain likes Director Jiang very much. When he hadn't had the chance to contact you before, he had read your story. This time he was very excited..."

"You can tell that you are very harsh." Mu Zhiyang closed the door of the dissection room and complained when he had time.

Chen Changfeng hurriedly said, "It hurts, but it doesn't hurt that much, and they are all familiar locations and are tired."

"This is considered a workplace bullying." Maki Shiyang said.

Chen Changfeng shook his head quickly: "No, our captain is a post-80s generation, the second dimension, and he works according to the template of Akagi Takaki. He is actually very good to me."

Mu Zhiyang curled his lips: "If you should resist, you still have to resist."

Miao Ruixiang next to him asked curiously: "What is Akagi Takaki?"

"It's a character in the comic "Slam Dunk"," Chen Changfeng explained.

Miao Ruixiang said he understood: "What is the story of "Slam Dunk"?"

...

When Jiang Yuan first dissected the male corpse, he took out all the photos of the wounds and placed them in front of him to read them carefully.

In the murder investigation, the weapon is always the top priority. When Jiang Yuan was young, Ningtai County's funds were so tight that Huang Qiangmin would drain the water from the river to find the weapon in order to search for the weapon. Shen Yaowei also traveled all over the garbage mountain to find the weapon.

In a murder case, either the police can tell the truth clearly or the truth clearly. If you can’t find the weapon, how can you tell it clearly?

Especially when it comes to the inspection and court process, whether there are weapons or not is a two-way environment. If you don’t mention the country, just take the United States as an example. Without weapons, how do you ensure that the big American police did not use the big recovery technique, how do you ensure that the suspect is not being punished, but how can you ensure that the stupid big American police will not make any mistakes in the investigation and that Li Dai Taoshou will not happen.

Of course, having a weapon is actually not enough to prove it, so many chains of evidence including the weapon are also needed to prove it.

In murder investigation, the weapon is often a key, especially in this chaotic situation, many traces on the body are washed away by the rain, and the darkness and suburbs make it difficult for surveillance to play a role. At this time, finding the weapon will naturally bring a series of clues.

Especially for this male corpse, when Jiang Yuan found that the wound was not caused by professional knives, he decided to try to find a weapon.

What Jiang Yuan mentioned is actually talking about "ordinary tools", and it is more likely to be ordinary tools held by professionals rather than professional tools held by ordinary people.

For Jiang Yuan, who has the "trace inspection-tool trace inspection (LV6)", this is the easiest clue he has seen to investigate.

Although the murderer's wound was not easy to make a weapon because he had been disturbed, it was at most a difficulty between LV3 and LV4. If it was a dissection, combined with glue injection or scanning, Jiang Yuan estimated that there was an LV3 perfection. If he had money, he could basically draw a similar conclusion.

Unfortunately, Shen Changfeng was responsible for the first dissection.

There is nothing to say about this. Donghua City is also limited to Qinghe City. When Jiang Yuan was not in Ningtai County, the local forensic doctor was either Miao Ruixiang or Wu Jun, and he was also limited to his strength.

Pathological anatomy itself is not difficult. After solving the problems of nausea and vomiting, after graduating from the ordinary forensic university, I became basically proficient after working for a year or two. I could write daily autopsy reports very smoothly. The key is that murder cases are difficult to find, and serial killers are even more scarce.

Although Shen Changfeng dreamed that one day he encountered a big case, he killed it out of nowhere and received applause from his colleagues and the second dimension, what he did was to die in a car accident, suicide, and accidental death, which meant that he had been working as a social screw in his entire career. Suddenly, a slightly decayed corpse appeared in front of him...

It is no longer easy to ask Shen Changfeng to make a judgment, and it is a bit unrealistic to ask him to be able to cover everything.

Fortunately, Shen Changfeng's basic operations are standardized. He took photos where it was time to take pictures, and there were videos throughout the autopsy. Young people who graduated from professional schools have this benefit, especially those who graduated from good schools. No matter how excited they feel, they can always be patient and complete the most basic work.

On the contrary, he cannot infer the appearance of the weapon based on the appearance of the wound, and such a thing should not be required by a certain forensic doctor.

A normal forensic doctor needs to develop an LV3 skill, and it takes 10,000 hours to start. But today's corpse requires the appearance of a weapon, tomorrow's corpse needs to be restored to the skull, and the day after tomorrow's corpse requires forensic anthropology. How could there be such a person in the grassroots unit?

In addition to Jiang Yuan, there are also various Eight Tigers.

As for the experts invited in Donghua City, they should have a tool identification level of LV3 or above, otherwise they will not be called an expert. However, it is difficult to identify the tool for this body, and the difficulty of secondary dissection is also high. In addition, the factor of decay, simple tool identification, even LV4, is probably not easy to use.

However, these are not difficult for Jiang Yuan.

In addition to the trace detection of LV6 and the trace detection of tool trace detection, there are also the skull restoration of LV4, the image enhancement technology of LV5, the image recognition and analysis of LV5, and the latter three models are much more difficult than a murder weapon.

You can do it well, but the steps you should do are not omitted.

Jiang Yuan first needs to sif the photos. Not only do the photos involving the wound, but also pay attention to the lens and distortion control. It is good for Chen Changfeng to calm down and complete the photo task, but there should be still a gap from the criminal photography of LV2.

After filtering the photos, perform quality assessment, Jiang Yuan then calibrates the photos that need to be used, that is, calculates the actual length corresponding to each pixel, and finally selects a reference point to align the photos from multiple angles in space.

When doing this step, Jiang Yuan used Agietashape.

That is, when I was doing this, a child around me who was studying hard and taking notes was slightly broken.
