Rainy nights are a natural bug in modern criminal science.

The Lockard principle of material exchange that is often mentioned by people - when two objects come into contact, material transfer will occur, which will take away something and leave something behind - it is the foundation of criminal investigation.

Most criminal investigation techniques follow the Lockard principle of material exchange. Under this principle, the beauty of the world is like elementary mathematics, as if everything is self-consistent and has solutions.

Time is a heavy blow to the principle of Lockard's material exchange. As time goes by, many evidences will gradually disappear and then disappear.

But the confrontation time itself is the most familiar and receptive part of human beings...

It's different on rainy nights.

It can sweep away evidence and change the crime scene on the day of the crime.

The rainfall from the sky, falling on the corpse, the ground, and even the suspect's body, may wash away the evidence. However, when it exchanges the transferred rainwater, it obviously cannot bear criminal responsibility.

There are many famous major and mysterious cases that happen on rainy nights, and it is not without reason.

Of course, rainy nights also have disadvantages, but no matter how you find a compensation, once a murder occurs on a rainy night, it will be at least more than +1.5.

Some ordinary and ordinary cases may be small cases with difficulty of about 0.5. With the blessing of a rainy night, they may become 2.0 difficulty, which is enough to make policemen below the backbone level helpless.

In the famous butcher case on a rainy night, the murderer, as a taxi driver, killed four women one after another. He was named because the crime was mostly committed on rainy nights.

This case has a huge impact and can be said to be the most famous serial murder case in the Hong Kong area. There are countless police forces mobilized. Not to mention the various cases during the case, from the perspective of hindsight, the murderer is neither professional nor smart. Because he was arrested, he took photos of the body and organs to the photo studio to wash them.

There is no need to be too professional or smart. The murderer will never do such stupid things if he has read a detective novel.

But such a stupid person, with the blessing of a rainy night, actually avoided the positive investigation of the Hong Kong police force, which is known as professional.

However, no one joked about the Hong Kong team. Because the more famous Scotland Yard, the FBI, or the Tokyo Search lessons all have similar embarrassing stories.

Obviously, for Liu Jinghui, who claims to be Shannan Mos, the murder case on a rainy night was really a very exciting point.

"How is the murderer's method of killing people, abandoning corpses, and cutting off the uterus?" Liu Jinghui did not look at the photos carefully, but instead diverged from his own thinking. Whenever he thought of it, he asked Jiang Yuan.

Jiang Yuan closed his eyes and recalled for a moment, saying, "The incision is strong and the marks are neat. The murderer is most likely to be a male and strong. As for the operation of uterus dissection, it is not based on anatomical structure. It is basically based on brute force. The order of dissection should be taken from the abdomen, and there is no process of searching. It means that you know the location of the uterus. Can this be considered a proficient technique?"

"If you have a skillful technique, does it mean that it is not the first time you have killed someone?" Liu Jinghui asked this question, then looked at Cui Qishan and others next to him, and said, "I see that your previous investigations have also had such speculations?"

"Yes, we have also looked for some of the previous cases, especially those that occur on rainy days, or those who have uterus cut off, but we have not found any suitable cases for parallel connection." Cui Qishan answered quickly.

Serial connection is the secret to solving cases, especially after setting up a special task force and having enough manpower, it is common to find old cases.

Liu Jinghui nodded slowly: "Where is the case outside the capital?"

"No, it is a very bad behavior to cut organs. There are elements like rainy nights. If there is a similar case, you don't need to look for it. You will know if you ask me." Xiao Si, who answered this time, pointed outside and said: "The flow of people in the capital is complicated, and it is very likely that people from other places are committing crimes. The key is that the victim is a local from the capital and works in the capital. How can he be selected as a victim?"

Liu Jinghui said: "The action of dissection of the reproductive organs is often very symbolic. The murderer chose this victim, probably not because of his identity or interpersonal relationships. Of course, this is also a speculation...a previous investigation..."

"The victim has an aunt who participated in an illegal church, but she has not reached the point where she wants to kill people. At most, she is cheating money and sex... As for other aspects, if the murderer chooses randomly, there will be investigations in this direction, and there will be no results..."

"Let's reorganize the evidence." Jiang Yuan did not ask Liu Jinghui to continue asking.

They themselves have no corresponding understanding of this case, and just asking, the efficiency of obtaining information is too low.

With Jiang Yuan's words, everyone in the room read the file according to their usual directions.

Wang Chuanxing continued to serve Jiang Yuan alone, showing him photos of various corruption and corrupt bodies, as well as various traces of the scene.

There are many former, while there are very few latter, and most of them are traces around them, and they may not be left by the murderer or victim.

When Cui Qishan looked at the traces in Jiang Yuan, he said: "It often rains heavily in the capital. The night before the body was found, the rain was very heavy, and there was wind. The area where the body was located would pass through water. Even if there were footprints or something, it might not be left."

"You still keep the clothes on the corpse, right?" Jiang Yuan tapped the screen at this time.

"It's been kept, but it also corrodes most of it. Remember it should be cotton fabrics or something." Cui Qishan said, looking at Jiang Yuan with hope and asked, "Can forensic botany be used?"

For the criminal police, Jiang Yuan’s forensic botany is a bit like a big move. Even if he cannot defeat the enemy with one move, he can at least get some blood.

Jiang Yuan was amused by Cui Qishan's tone and said, "You can take some spore powder for later use. If you really want to find a pollen map, you will have to fight. You don't have a complete plant map, right?"

"What you are talking about." Cui Qishan quickly admitted. Jiang Yuan said that "a big fight" and he would dare to take the blame, because he was afraid that he would be a big fight by the bureau.

The newest ⊥小⊥小⊥ said⊥⊥⊥⊥⊥⊥⊥⊥⊥⊥!

"Then let's go here first. I'll go see the corpse. If others are there, please arrange it?" Jiang Yuan directly gave Liu Jinghui the order.

Liu Jinghui responded without hesitation, and then skillfully began to arrange different people, from surveillance videos to alarm calls, transcripts, etc., to investigate one by one.

Jiang Yuan’s special team has done too much similar cases. Although the task force in front has done so much work, if you want to restart the task force, you must do the investigation that can be done. Otherwise, those who are suspicious will delay their efforts. Of course, this is also a resource that Jiang Yuan’s special team has. Ordinary guest soldiers cannot afford this set.

Jiang Yuan went to the forensic building to see the body.

The corpses two years ago were always stored in an ice coffin because the case was not solved. Until yesterday, they were frozen and hard.

This method can maintain the original appearance of the corpse to the greatest extent, just like the zombie meat that is often mentioned on the market. Think about the remains of chickens, ducks and pigs, which can be kept for twenty or thirty years, and it is not surprising that human bodies have been preserved for more than two years.

Unfortunately, when the body was found, it was already slightly corrupt. After it was frozen and melted, the muscles and other tissues gradually became odorous as they bleed.

Jiang Yuan had already made preparations and had full body protection, so he started the secondary dissection without saying a word.

Zhan Kan arranged people and started to burn hot water.

The secondary anatomy can be done very limitedly, and it will be almost done to get something from the location where you can still sample it.

After finishing this step, Jiang Yuan sent someone to throw the remaining corpses into hot water and start to remove bones.

Finally, the anatomical table turned into pieces of gray-white bones.

Jiang Yuan swept over from top to bottom.

"Is the victim 38 years old?" Jiang Yuan picked up a rib and suddenly asked.

"The file is 38 years old." Wang Chuanxing quickly answered.

Jiang Yuan shook his head: "This corpse is only about 33 years old."
