In an interrogation room in the Jiangnan District Prosecutor's Office, the lights are bright.

Chen Geng stood in front of the table, pointing to the corpse assembled from the photos on the table, simulating the autopsy process.

"1. Comparing the hair collected in Liu Renna's apartment, after DNA testing of the deceased, it was found that the deceased was undoubtedly Liu Renna.

2. Although there were a lot of blood stains on the surface of the corpse, there were no obvious external injuries on the surface of the body.

The only external wound was here, all ten fingers of the deceased were severed, and the blood stains in various parts of the house mainly flowed from here.

Through the facet observation, the ten fingers of the deceased were cut off before the deceased's death.

However, the 10 severed fingers were not found at the scene. ”

When Chen Geng introduced this, Jin Yunhao immediately interrupted and asked his own questions:

"The murderer must have cut off ten fingers and hid them, there must have been a purpose, he was hiding some important information. What information can the forensic doctor tell from his fingers? ”

Chen Geng immediately replied: "Fingerprints, fingerprints and DNA are the most important means of identity identification. ”

Hearing the conversation between the two, Shen Donghai wondered: "Could it be that the murderer wants to hide the identity of the deceased?" ”

Chen Geng glanced at Shen Donghai as if he was looking at an idiot.

Kim Yoon-ho took care of his own people's face and explained: "No, the deceased was killed in his home, as long as the hair in the house is tested and compared with the deceased's DNA, it is easy to determine the identity of the deceased."

If analyzed from a psychological point of view, the murderer cut off the ten fingers of the deceased, and should experience the thrill of committing a crime from the pain of the deceased. As for why the ten fingers that were cut off were hidden. It is not known for the time being. ”

Chen Geng nodded. Agree with Kim Yoon-ho's analysis. Seeing that Kim Yunhao had no other questions, he continued to explain:

"3. The hands and feet of the deceased were entangled in duct tape and could not move freely.

4. The deceased's head was wrapped in layers of duct tape and could not breathe. Judging from the blood congestion in the deceased's eyes, the direct cause of death of the deceased was suffocation.

But there was a peculiar circumstance, after cutting off the tape on the deceased's head, it was found that the deceased's mouth was sealed with tape in advance. ”

Kim Yoon-ho concluded. And let Yin Guohong on the side be responsible for recording:

"The purpose of sealing the mouth of the deceased with duct tape in advance should be to allow the deceased to witness the whole process of his finger being cut off. It can be seen that the murderer was very excited when he committed the crime, which means that he was having a good time. ”

Chen Geng waited for a moment and continued to introduce:

"5. The time of death of the deceased was about 10 o'clock last night.

It's summer, but the bed where the deceased is lying is electrically heated. It is possible that the murderer wanted to speed up the decomposition of the deceased's body in this way and interfere with the forensic doctor's determination of the specific time of death.

However, combined with the confessions of nearby residents at the time, the time you arrived at the scene, and the situation of the corpse. The time of death of the deceased can be preliminarily determined.

6. From the surface of the corpse, there are no traces of strong resistance in the yin/tract of the deceased.

Observe the body's yin/canal. No signs of contraction of the uterus/cervix were found, and no estrogen was secreted. In the yin/tract, no male semen/fluid residue was found

That is, the deceased was not sexually assaulted in front of him.

7. At the scene of the murder, no hair or fingerprints other than the deceased were collected.

8. The footprints left on the floor at the murder scene were also owned by the deceased after identification.

In other words, the murderer did not leave any direct physical characteristic evidence at the scene of the murder.

This is the result of the autopsy. ”

After listening to Chen Geng's explanation in one breath, Kim Yunhao frowned and concluded: "The murderer did not sexually assault the deceased, and he did not leave any evidence of identity at the crime scene, which shows that he is very calm, extremely calm."

First, he excitedly cut off the deceased's ten fingers and let the deceased witness the whole process.

Then, it was very restrained and calm.

In the short time of committing the crime, the two emotions of excitement and calmness coexist, which is not something that ordinary people can do.

The murderer in this case is rare in his life. ”

After listening to Jin Yunhao's analysis, Yin Guohong, who was in charge of recording, nodded, and Shen Donghai also felt very reasonable, and looked at Chen Geng proudly.

But Chen Geng still has that cold look, during the autopsy, the prosecutor of the Grand Prosecutor's Office also analyzed these things, and he didn't think that Kim Yunhao was much more powerful than those people.

Seeing that there is no problem with Jin Yunhao, Chen Geng continued to simulate the second part of the autopsy.

"After an internal autopsy of the corpse, it was found and confirmed that:

1. An autopsy of the stomach of the corpse found that there was food residue, and according to the digestion of the food, the time of death of the deceased was about 10 o'clock, which was consistent with the time of death previously judged.

2. The deceased was indeed suffocated to death, and there is no possibility of death caused by other drugs.

However, it should be noted that the residual anesthetic was detected in the body of the deceased, and the dose was normal, which belonged to the conventional hand speed anesthetic dose. ”

"Anesthetics?" Kim Yun-ho was surprised: "Can you tell whether this anesthetic was injected before or after the deceased's death?" ”

Chen Geng replied: "Before death." Because these anesthetics have spread in the body of the deceased and are working. Therefore, it can be very confident that it was penetrated before the death of the deceased. ”

Shin Donghae interjected: "That's weird. According to your analysis, the murderer's purpose should be to inflict more pain on the deceased and find pleasure in it.

However, if the deceased is given an anesthetic, then the deceased will not feel undue pain.

How do you explain this? Isn't that a contradiction? ”

He asked the question that was on everyone's mind.

Kim Yoon-ho thought for a moment and came up with a hypothesis: "I don't know if you've ever heard of a famous experiment.

In Poland, a doctor of psychology named Norgland conducted an experiment on a death row prisoner in 1981.

Norgland took the condemned prisoner to a secret room, informed him in advance that he would be executed, then blindfolded, slashed the back of his knife across his wrist, and let out the ticking sound of water.

Death row prisoners did not bleed at all. But he eventually died. The doctor's explanation was: He died of fear.

This experiment is a mental test. It is also a form of hypnosis.

In fact. The prisoner did die of organ failure caused by excessive blood loss, even if he did not lose a drop of blood. He was first hinted at by all kinds of signs that he was going to die, and combined with what happened afterward, he was even more convinced that he was going to die.

So, under this mental suggestion and inner fear, his body reacted, and various organs failed and stopped working, and he died a natural death. ”

After listening to Kim Yoon-ho's story. Shen Donghai hurriedly asked:

"Boss, you're saying that the murderer also knew about the experiment. He deliberately administered anesthetics to the deceased and then showed the deceased to see his fingers cut off.

Later, although the deceased did not feel great pain, he saw that he was bleeding profusely, and he thought that he was going to die. Did she end up dying the same as the condemned prisoner in the experiment? ”

Kim Yun-ho didn't answer Shin Dong-hae's question, and instead turned his attention to Chen Geng, wanting to hear professional advice.

After Chen Geng looked at and compared the autopsy photos, he shook his head and said:

"The deceased's heart and other organs did fail. A large amount of adrenaline was also detected inside the organs of the deceased, after which the deceased was afraid. Naturally secreted by the body.

But this is not the basis for your guesses.

Because, if the deceased is in front of the murderer, simply suffocating to death, the above situation will also occur. ”

Seeing that Chen Geng's professional forensic doctor could not give a definite conclusion, everyone felt that this case was becoming more and more complicated.

Is Yoo In-na simply suffocated to death, or is she scared to death by fear in her heart as Kim Yun-ho analyzed. Or is it a combination of both?

None of them can give a definite answer.

But for the assumptions put forward by Kim Yunhao, Chen Geng was very satisfied.

He was a Ph.D. in psychology and had certainly heard of this famous experiment.

However, during the first autopsy, the prosecutor of the Supreme Prosecutor's Office did not mention this hypothesis, and Chen Geng could not make an accurate judgment.

In addition, he couldn't interject and didn't agree with those prosecutors, so he didn't talk too deeply about this uncertain topic.

It was only at this time that Chen Geng discovered that Jin Yunhao's professionalism was still good, at least on this issue, he was much stronger than those prosecutors in the Grand Prosecutor's Office.

He also felt like he had met a soulmate.

Although he can't do anything about this issue, it doesn't affect him to show his professionalism in front of Kim Yun-ho.

Picking out a few photos, he added: "Although, I can't give a definite judgment on this issue, but in order to make up for it, I offer you a new discovery."

Look here, this is an examination of the deceased's gastrointestinal tract after autopsy.

The deceased's stomach was very healthy before his death, and his health was much better than that of an ordinary adult woman. This is something I've never encountered when I dissect a Korean corpse.

In addition, the overall thickness of the deceased's gastric mucosa is much higher than that of a normal Korean woman, but it is within a reasonable thickness. It will not make the body uncomfortable.

Thickening of the stomach mucosa is usually caused by the body's regular ingestion of irritating foods.

However, there is also a situation in European and American countries, that is, often eating raw beef and mutton, or eating half-cooked beef and mutton, will also cause the gastric mucosa to thicken.

Because the stomach has to digest these raw meats that are not easy to be decomposed, it secretes a large amount of gastric acid, which stimulates the growth and thickening of the gastric mucosa.

Apart from this circumstance, I can't explain why the gastric mucosa in Liu Renna's stomach is so thick and does not affect her health at all. ”

Chen Geng's discovery was mentioned to the prosecutor of the Supreme Prosecutor's Office, but those people did not pay attention to it at the time.

Because this discovery has nothing to do with the cause of death of the deceased.

Coupled with the complexity of the human body, everyone's physical condition is different.

Therefore, those prosecutors didn't care about this, and even thought that Chen Geng was deliberately selling his professional knowledge and providing them with some boring information.

But Kim Yoon-ho doesn't think so.

The case can't be solved because the evidence has not been found and has been collected.

At this stage, he will not let go of any clues, evidence. (To read the latest chapter of this book, please go to [Wind and Rain Novels www.44pq.com]......)
