Chapter 46 Autopsy


Chapter 46 Autopsy

Lin Sheng sighed: "Oh my God, this is the most outrageous case of hiding a body in cement that I have ever seen!"

Xu Yiqing also shook his head: "Don't say it's you, it's my first time seeing you."

Xu Yiqing had seen too many ordinary corpse dismemberment cases and corpse-hiding cases in cement, but this was the first time he had seen the death of the deceased so much later than the time when the statue was built.

It's like burying a person alive in concrete... But when the concrete base was built, He Yunke wasn't even missing.

Besides, this was a corpse dismemberment. The murderer mixed the body fragments into the cement, which resulted in the dismemberment.

He looked around at the concrete remains piled in the corner of the autopsy room. When they were delivered, the cement was in pieces here and there, and highly decomposed corpses were firmly buried in each part.

Lin Sheng couldn't help but wonder: "How did the murderer do it?"

Xu Yiqing thought for a moment and said: "I don't know, we are not detectives after all. But I think as long as the murderer can be caught, the method of committing the crime will definitely come to light."

The most important responsibility of the medical examiner is to ascertain the cause of death and provide sufficient evidence for the criminal police to handle the case. In this way, it was worthy of the deceased to lie down on the autopsy table.

Lin Sheng was recording the autopsy report. He asked: "Does the identity of the corpse indicate that the deceased is He Yunke?"

Xu Yiqing replied: "The blood relationship cannot be determined based on DNA alone. We must be foolproof and have absolute evidence to determine the identity of the deceased."

Lin Sheng asked: "What should we do? The body has rotted like this."

Because he was a forensic doctor who switched to surgery midway, and his career was short, Lin Sheng lacked experience when facing many major and important cases.

At least there hasn't been such a bad corpse dismemberment case in Jiangcheng for a long time, and the corpse has been highly decomposed, with only some rotten organs and muscle tissue separating it from being completely skeletal. It can be said that this is the first time Lin Sheng has faced such a badly decomposed corpse since he became a forensic doctor.

Xu Yiqing said: "Then I will teach you two methods to confirm the identity of the deceased even in a highly decomposed state. The first method is used when there is information about the suspected source of the corpse, such as the body being claimed, or the decomposing corpse found in the residence. .”

He walked to the dissecting table and straightened the skull with both hands: "Overlap the skulls and compare the skull of the unknown corpse with the head photo of the suspected deceased. Take photos in the same direction and angle and then overlap them for observation. Focus on the mouth, nose and eyes. The position of the eye socket, nasal septum and gums are determined. ”

Lin Sheng silently made a note in his mind to increase his ability to be independent in the future.

"But Brother Xu, if we can already determine the blood relationship, is it still necessary to do a cranial superposition?" He thought for a while and sighed: "It would be great if fingerprints could be extracted."

The body of the deceased was highly decomposed, and the fingers were almost entirely covered with grease left by decay. In this case, the possibility of extracting fingerprints was zero.

Xu Yiqing was confident: "This is the second method...you go and prepare the dichlorotoluene solution."

Lin Sheng did as Xu Yiqing said and brought dichlorotoluene solution.

Xu Yiqing said: "Soak the corpse's fingers in the solution, wash them several times, and then apply them with acetone."

Lin Sheng applied acetone to the fingers of the deceased that had been washed with solution many times. After the acetone dried, he suddenly found that fingerprints reappeared on the fingers of the corpse that were originally full of grease!

"Yes!"

He scanned the extracted fingerprints and transmitted them to the Investigation Division of the Criminal Police Brigade.

Soon the logistics police gave feedback that the fingerprints of the deceased basically matched those of He Yunke!

After confirming the source of the corpse, Xu Yiqing did not show any relief. Instead, he sighed softly: "Now the source of the corpse information can be written about the deceased He Yunke."

He Yunke is really dead.

You have to investigate the truth behind that photo piece by piece.

And just as Du Yu was worried, the people in the photos died mysteriously one after another, and the unfortunate curse would fall on him without knowing when. After the identity of the deceased was determined, the focus of the autopsy became the cause of death.

In ordinary criminal cases, the vast majority of forensic doctors determine the identity of the unnamed corpse, and then leave the rest of the work to the criminal police, who investigate the murderer and motives based on the deceased's interpersonal relationships, and finally ask the murderer to explain the crime process.

So the people who are most tired and stressed about homicide are the police.

But in Jiangcheng, Xu Yiqing will do everything within his duties to the extreme and try to lighten Du Yu's work as much as possible.

As long as the identity of the corpse, the cause of death, the time of death, and even the tools and motives of the crime were obtained, he omitted all the information that could be obtained from the corpse, which greatly relieved the pressure on the criminal police.

Xu Yiqing and Lin Sheng stood next to the minced meat and human bones made into human figures, and began to examine any details that could determine the cause of death.

Lin Sheng first went to observe the broken bones of the corpse. He held it in front of his eyes and looked at it carefully. Then he touched the section and said, "It's a saw. The murderer used tools like saws to dismember the body. The bones were not chopped, but sawed." And the murderer is very experienced and calm, and knows how to cut the body apart with the least effort... The fractures are all at the weakest parts of the bones."

Xu Yiqing examined the few remaining muscles and tissues and concluded: "The murderer froze the body before dismembering it. Frozen meat is more convenient to handle with a saw, and the body of the deceased has tissue dissolution left by thawing."


Lin Sheng wrote in the autopsy report: "The body had been frozen, and the murderer had a freezing container that could hold the entire person."

After finishing writing, he began to check other bone injuries. Because the corruption was so serious, superficial injuries could no longer be investigated. The cause of death had to start with the wounds left on the bones.

Check out the 16-9 book bar and see the correct version!

It was ultimately determined that there were two main injuries to the bones of the corpse——

There were cracks and scars on the skull, and tiny nicks on the tibia and ribs, all of which could have been fatal!

Xu Yiqing said: "We must first determine whether these wounds were caused before death or during the dismemberment process... Let's do bone grinding."

Lin Sheng said: "I will do it. I am good at this."

Bone grinding, as the name suggests, is to cut the bones near the wound into bone slices about one millimeter thick and observe them under a microscope.

If it was a scar left by the murderer before He Yunke's death, then the bleeding around the scar would penetrate into the bone, and hemoglobin would appear under a microscope. On the other hand, if the traces are formed after freezing and dismemberment or during the decay process, there will be no heme in the bone grinding films.

Lin Sheng took a fine whetstone and started working on it. The bone grinding piece he made was very standard, comparable to a textbook.

"Brother Xu, there are small dots of heme on the bone grinding disc!"

Xu Yiqing nodded: "Then it is certain that the wounds were formed before death, and such dense wounds in the fatal parts can be preliminarily determined to be the cause of death."

Lin Sheng recorded the new findings and carefully observed the wounds on the skull, tibia and ribs: "The bones are all sharp wounds, similar to those made by an axe. But at this depth, it would be too shallow for an axe. .”

He frowned and thought. The ax was originally designed for slashing, so the mechanical design was more labor-saving.

Even people with less strength, such as women and teenagers, can easily split a person's skull, causing a penetrating injury to the skull instead of just leaving such scars on the bone surface.

Xu Yiqing thought for a moment and said: "It's something similar to a machete. It cuts open the skin and flesh, and then leaves scratches on the bones."

So what kind of knives are most common in cities and can leave similar wounds?

The two looked at each other and said in unison: "Chop knife!"

He Yunke was stabbed several times in the head, neck and chest with a kitchen knife. He eventually died of excessive blood loss!
