Chapter 1237 Bone Removal
Rainy nights are a natural bug in modern criminal science.
The often-mentioned Locard principle of exchange of materials - whenever two objects come into contact, material transfer will occur, that is, some things will be taken away and some things will be left behind - it is the foundation of criminal investigation.
Most criminal investigation techniques follow the Locard principle of material exchange. Under this principle, the world is as beautiful as elementary mathematics, as if everything is self-consistent and has a solution.
Time is a heavy blow to Locard's principle of material exchange. As time goes by, many pieces of evidence will gradually disappear and then disappear.
But fighting against time is the most familiar and resigned part of human beings...
Rainy nights are different.
It can wash away evidence and alter the crime scene on the day of the crime.
Rainwater falling from the sky, falling on corpses, the ground, or even on the suspect's body, could wash away evidence. The rainwater transferred back by the rainwater in exchange obviously cannot be held criminally responsible.
There is a reason why many famous major cases and mysteries happened on rainy nights.
Of course, rainy nights also have their disadvantages, but no matter how you make up for it, if a murder happens on a rainy night, the difficulty is at least +1.5.
Some ordinary, unremarkable cases may have originally been small cases of difficulty around 0.5. With the blessing of a rainy night, they may directly become a difficulty of 2.0, which is enough to make police officers below the backbone level helpless.
In the famous Rainy Night Butcher case, the murderer, who was a taxi driver, killed four women one after another. The case got its name because most of the crimes took place on rainy nights.
This case had a huge impact and can be said to be the most famous serial murder case in Hong Kong. Countless police forces were mobilized. Not to mention the various things that happened during the case, from the perspective of hindsight, the murderer was neither professional nor smart. He was arrested because he took photos of corpses and organs to a photo studio for development.
You don't have to be very professional or smart. If the murderer has read a detective novel, he won't do such a stupid thing.
But such a stupid person, with the help of the rainy night, actually evaded the direct investigation of the so-called professional Hong Kong Police Force.
However, no one laughs at the Hong Kong team, because the more famous Scotland Yard, FBI, or Tokyo Investigation Division all have similar embarrassing stories.
Obviously, for Liu Jinghui, who calls himself Shannan Moss, the murder case on a rainy night is indeed a very stimulating point for him.
"Murder, abandonment of body, and removal of uterus, how did the murderer do this?" Liu Jinghui did not look at the photo closely, but let his thoughts wander. He asked Jiang Yuan whatever he thought of.
Jiang Yuan closed his eyes and thought for a while, then said, "The incision was strong and the cut marks were sharp. The murderer is most likely a male and strong. As for the operation of removing the uterus, it was not performed according to the anatomical structure. It was basically done by brute force. The order of removal should be from the abdomen. There was no searching process, which means that the location of the uterus was known. Can this be considered a skilled technique?"
"If the method is sophisticated, does it mean that this is not the first time he has killed someone?" Liu Jinghui asked this question, then looked at Cui Qishan and others beside him and said, "I saw that your previous investigation also had such a guess?"
"Yes, we also looked through some of the previous backlog cases, especially those that occurred on rainy days or those involving hysterectomy, but we couldn't find any cases suitable for series and parallel connection." Cui Qishan answered quickly.
Connections in series and parallels are the secret to solving cases, especially after a task force is set up and there are ample manpower, it is common to look for old cases.
Liu Jinghui nodded slowly: "What about cases outside the capital?"
"No, organ harvesting is a very bad act. There is also the element of a rainy night. If there are similar cases, there is no need to look them up. You will know everything by asking." Xiao Si answered this time. He pointed outside and said, "The flow of people in Beijing is complicated. It is very likely that outsiders committed the crime. The key is that the victim is a local of Beijing. He went to school and worked in Beijing. How was he chosen as a victim?"
Liu Jinghui said: "Removing reproductive organs is often a very symbolic action. The murderer probably chose this victim not because of his identity or interpersonal relationship. Of course, this is also a guess... the previous investigation..."
"The victim has an aunt who attends an illegal church, but she didn't kill anyone. She just cheated them of money and sex... As for other aspects, if the murderer was chosen randomly, we have also investigated this direction, but there is no result..."
"Let's reorganize the evidence." Jiang Yuan did not let Liu Jinghui continue asking.
They themselves don't have the corresponding understanding of the case, and it is too inefficient to obtain information just by asking questions.
After Jiang Yuan said this, everyone in the room started reading the files according to their usual directions.
Wang Chuanxing continued to serve Jiang Yuan alone, showing him various photos of deformed and decayed corpses, as well as various traces at the scene.
There are a lot of the former, but very few of the latter, and most of them are traces in the surrounding areas, and they are not necessarily left by the murderer or the victim.
While Jiang Yuan was looking at the traces, Cui Qishan said, "It often rains heavily in the capital. The night before the body was found, it rained heavily and there was wind. The area where the body was was flooded, so even if there were footprints, they probably wouldn't be left behind."
"You still have the clothes on the corpse, right?" Jiang Yuan tapped the screen at this time.
"It's still there, but most of it has corroded. I remember it was cotton or something." Cui Qishan said, looking at Jiang Yuan hopefully and asked, "Can forensic botany be used?"
To the criminal police, Jiang Yuan's forensic botany is a bit like a big move. Even if it can't defeat the enemy in one move, at least it can make the enemy lose some blood.
Jiang Yuan was amused by Cui Qishan's tone and said, "You can take some pollen for future use. If you really want to find a pollen map, you'll still have to make a big fuss. You don't have a complete plant map, right?"
"You're right." Cui Qishan admitted hastily. Jiang Yuan had already said "make a big fuss", and if he dared to respond, he was afraid that he would be made a big fuss by the bureau.
"Then let's go here first. I'll go check out the body. As for the others, can you make arrangements, Director Liu?" Jiang Yuan directly gave the order to Liu Jinghui.
Liu Jinghui agreed without hesitation, and then skillfully began to arrange different people to investigate one by one, from surveillance videos to police calls, transcripts, etc.
Jiang Yuan's backlog team has handled too many similar cases. No matter how much work the previous task force has done, if you want to restart the task force, you must do all the investigations you can. Otherwise, you will be suspicious and waste your time. Of course, this is a resource that only Jiang Yuan's backlog team has. Ordinary guest troops cannot afford this.
Jiang Yuan went to the forensic building to see the body.
The body from two years ago had been kept in an ice coffin because the case had not been solved. Until yesterday, it was frozen solid.
This method can preserve the original appearance of the corpse to the greatest extent, similar to the so-called zombie meat on the market. Considering that the remains of chickens, ducks, and pigs can be preserved for 20 to 30 years, it is not surprising that human remains can be preserved for more than two years.
Unfortunately, when the body was discovered, it was already slightly decomposed. After being frozen and thawed again, the muscles and other tissues gradually turned into rotten meat as they thawed.
Jiang Yuan had already made preparations. After putting on full body protection, he began the second autopsy without saying a word.
Zhan Kan arranged some people to start boiling hot water.
There is very little that can be done during a secondary autopsy. It is enough to take something from the places where samples can still be taken.
After this step was completed, Jiang Yuan had the remaining body parts thrown into hot water and began to remove the bones.
Finally, what was placed on the dissecting table were gray-white bones.
Jiang Yuan scanned from top to bottom.
"Is the victim 38 years old?" Jiang Yuan picked up a rib and suddenly asked.
"The file says he's 38 years old," Wang Chuanxing replied quickly.
Jiang Yuan shook his head: "This corpse is only about 33 years old."
