Department of Psychology Forensic

Chapter 85 Everything you experience must have traces!
"Every general teacher has his own story. We must fully understand the general teacher who teaches us medical knowledge, and do a good job of preview before class."

Han Na's tone changed from the dignified one just now, and gradually became more serious. Compared with the previous dean, she now looks more like a teacher.

What she said is also something that every medical student needs to pay attention to when attending the general teacher's class. They must make sufficient preparations before class and fully understand the general teacher's situation.

This is like before performing an operation on a patient, one must have a clear understanding of the patient's vital signs, and one must not be careless in the slightest, otherwise major problems may occur.

Of course, as a forensic doctor, the idea is the opposite. There is no way to know the relevant information of the corpse before the autopsy. Instead, they need to find as much information as possible during the autopsy.

Forensic science students and medical students are interlinked in many medical theories, but they are diametrically opposed in thinking.

Zhou Zheng already had an internship at the Forensic Medicine Center of the Municipal Bureau, and he was no stranger to dead bodies. This time, he came to see Mr. General out of respect for the body donors.

not to mention……

He felt that the general situation of the teacher was very similar to someone he knew.

"This general teacher was dismembered by the murderer after his death, so the theme of this class is 'Mutilated Corpse'. I hope you can all gain something from this class."

Han Na's voice kept ringing from the stereo. After bowing and saluting, the medical students sat back in their seats, and all their eyes were focused on the middle of the auditorium.

Immediately, Zhou Zheng's eyes lit up. He didn't expect to have an unexpected harvest. He thought that this was just a teaching for medical students involving general teachers, but he didn't expect to jump on the corpse.

Whether it is a normal corpse or a mutilated corpse, these will be identified by a forensic doctor. This is obviously a class related to forensic science.

Now he still has an unresolved corpse throwing case in his hands. This matter hangs in his heart, and he has no way to let it go. This makes him more interested in this class.

All of a sudden, the audience focused on Han Na, listening to her dignified and serious narration.

"In any stage of human society, the practice of dismembering corpses has appeared, and dismemberment is regarded as an act of desecration of the human body!"

"The act of dismembering corpses often occurs in murder cases. According to the internal statistics of our forensic department, on average, 10 out of every 3 murder victims will be dismembered, which is a very high proportion of corpses."

"Of course, not all cases of mutilated bodies are homicides. There are also cases of accidental death, such as accidents encountered at work, misfortunes encountered during sports, relatively serious traffic accidents, and suicides by lying on the rails, etc. , there is a possibility of dismemberment of the corpse.”

Han Na speaks at a moderate speed and speaks fluently. It can be seen that there is no sign of reciting scripts. This level of courses can be played at will.

The students at the scene also listened with great interest. After all, what Dean Han Na said was different from the knowledge that could be learned in books. It belonged to the experience of forensic work for many years.

For other medical students, they are more interested in enriching their knowledge. However, for Zhou Zheng, Dean Han Na is in the leading position of forensic medicine. What he said about forensic medicine has a lot of meaning for him. great help.

Gradually, Zhou Zheng listened more seriously, his brain was running fast, and he kept Dean Han Na's words firmly in his heart while he kept thinking.

"Let's imagine from the perspective of the murderer, what is the purpose of dismembering the corpse?"

After Han Na finished speaking, her eyes swept across the crowd. From her point of view, the seats in the auditorium were filled with darkness, and no one's face could be seen clearly. However, she still did this for the purpose of Just to give people time to think.

The students at the scene were still immersed in the solemnity of Teacher Dati's arrival. In addition, Teacher Dati was still lying on the corpse bed in the auditorium covered with a blue cloth, and no one really dared to talk to him.

However, this has no effect.

Hanna raises this question just to get the students to think, not to interact.

"Actually, the answer is very simple. I believe most of you have guessed it. Dismemberment of corpses is one of the many ways to dispose of corpses. The goal of disposing of corpses is the same, that is, to cover up the fact of murder, to try to evade the sanction of the law."

After Han Na gave an explanation, she began to pace back and forth in the auditorium. The course was getting better and better, and the whole person's thinking state had entered the state, as if she was not lecturing to medical students, but to the grassroots of some counties. Forensic lectures.

"So, here comes the question, how to dispose of the corpse so that it won't be discovered?"

Hannah asked another question.

The scene was still silent.

In fact, this question, for many people at the scene, is indeed a bit out of line.

Except for students majoring in forensic medicine, what medical students usually learn is how to cure diseases and save lives, not kill and dismember the dead.

Jianghai Medical University has a forensic major, but the proportion of students majoring in forensic medicine is very low. More than 90% of the students in the school are regular medical students.

"I believe that after hearing this question, some of the students here will come up with a nearly perfect theory of killing in their hearts, but this is impossible!"

"Everything that has been experienced must have traces!"

"For anyone who wants to dump the body, it is impossible to hide his criminal behavior!"

Han Na's tone gradually showed a sense of majesty in a high position for a long time. It was a kind of confidence that came from within, as if what she said was the truth.

"Even under the most favorable conditions, disposing of dead bodies is inconvenient because of the size, weight and unmovable nature of the body."

"The scene of throwing corpses is often found in the second scene, and there are very few criminals who threw their bodies at the first scene."

"However, few do not mean none. Criminals who throw their corpses at the scene of the first crime often have very limited choices of locations. They are generally concentrated in the following places..."

When Han Na said this, she stretched out her hand and began to rub her fingers on it.

"Under the bed, in the cupboard, in the closet, in the bathroom, in the attic, in the pantry, in the garden dirt, in the shed, in the garage, in the chimney, on the patio, etc." The circumstances of the dumping of the corpses at the scene were all told.

"In fact, the proportion of corpses dumped at the scene of the first crime is very low. Most murderers are very anxious to remove the corpse from the crime scene, and they hope to keep themselves as far away from the evidence as possible."

"At this time, the murderer will face a series of practical problems."

"Can you move a whole corpse?"

"Will the process of moving the corpse be discovered?"

"Where will the body be moved?"

"How to deal with the dead body when we get there?"

"This is a series of issues to consider. Often when the murderers encounter such a problem, the first thought that pops up in their heads is to dismember the corpse and divide it up."

Han Na directly stated the entire chain of thinking, so that even medical students who are not majoring in medicine can clearly understand the change in the murderer's mentality after the murder.

Zhou Zheng listened more seriously.

Now he is facing the case of dismembering corpses on the cross-sea bridge, which is a case of dismembering corpses, dismembering corpses and throwing away corpses, which coincides with the topic of Dean Han Na's lecture today.

Just hearing this, he already felt the strong rhythm of thinking, and he faintly felt that after listening to the whole content of Dean Han Na's class, he would definitely gain something.

At present, there are no more body parts in the cross-sea bridge dumping case, and the information of the victim has not been confirmed. It is at a stage of no clue.

"After the murderer decides to dismember the body, he will face a series of problems."

"What kind of tools do you need to dismember the corpse?"

"Is this tool found in the field or is it a work-related carry-on?"

"Where does the knife start when dismembering a corpse?"

"During the dismemberment process, the corpse will leave a lot of liquid, how to deal with this liquid?"

"After the dissection is over, what kind of container and method should be used to carry the corpse?"

Han Na said one sentence after another. When she raised these questions, the students at the scene were thinking along with her thinking, substituting themselves into the perspective of the murderer.

This is a rare course experience.

They have not experienced such a course before.

It is quite a novel experience.

"If the murderer had premeditated the killing, then he might have thought about how to dispose of the corpse in advance. However, the vast majority of homicides are murders of passion, so the murderer cannot be so thoughtful."

"Once the murderer realizes that the victim is dead, all kinds of questions flood into his panicked mind, whether it was intentional or accidental."

"The vast majority of murderers have no experience in this field. It may be their first and only time to kill and dismember a body. They will inevitably expose a lot of clues and evidence in the process."

Suddenly, when she was talking about this, Han Na stopped, her voice stopped abruptly, and the scene became extremely quiet.

"The content of this lecture is a little bit off. I believe that some of the students here must be students of forensic science. This class will still be helpful to you."

"As for more medical students, the purpose of this class is to help them get a better understanding of this general teacher who was dismembered by the murderer."

"Dismemberment was a method of escape and was not a factor in the homicide."

"The logic of dismembering the body is to break the body down into manageable parts, so that it is easier to move the body away from the crime scene without attracting attention from others."

"According to the big data collected by our forensic department, the murderer and the victim in most dismemberment cases knew each other."

"As I said just now, the corpse throwing scene is often at the second scene, that is, the place where the non-homicide occurred, but the dissection scene often occurs at the first crime scene, and most of these places are in the murderer's place." home or the home of the victim."

"The murderer's tools for dismembering corpses are usually obtained locally. In most cases, they are knives in the kitchen. This is one of the few tools that can be obtained in normal people's homes with the ability to dismember corpses."

"Here I have to mention a key location, the bathroom!"

"The design of the toilet allows the liquid to drain easily, and it is also very convenient to clean up the scene, so this is the place where the murderer often chooses to dismember the corpse indoors."

"So, for indoor dismemberment cases, the on-site investigation usually focuses on the inspection of the bathroom."

"The above-mentioned dismemberment behaviors are collectively referred to as defensive dismemberment."

As Han Na talked, her thoughts diverged, she raised her right hand, separated her five fingers, and swayed towards the crowd in the auditorium, attracting everyone's attention.

"Based on a large number of investigations and the criminal's intentions, we have summarized five types of dismemberment behavior, most of which are defensive dismemberment."

"Defensive dismemberment mainly refers to the fact that the reason for the murderer's dismemberment is to dispose of the corpse as conveniently and quickly as possible, and the purpose is to destroy evidence and cover up the crime."

After finishing speaking, Han Na looked at the watch on her wrist and recycled the topic.

"All right."

“It’s a bit off topic to tell everyone this.”

"Next, let's witness this general teacher together!"

"She will continue to lead everyone to progress in the next study."

Having said that, Han Na slowly pulled back the blue cloth covering the corpse bed under the eyes of countless medical students in the auditorium.

Suddenly, a corpse wearing a shroud appeared in everyone's sight.

This is a female corpse, which has been shaved. From the outside, it seems impossible to directly see the place where the dismembered body was dismembered. It seems to be sleeping and lying quietly on the corpse bed.

young!

This was the unanimous thought that popped up in the minds of the medical students present.

I hope that when they study with the general teachers, those general teachers are not young. Due to the particularity that the general teachers need to apply for body donation in advance, it is rare to see young general teachers.

however……

After this face was reflected in Zhou Zheng's eyes, his pupils shrank sharply.

Sister Yanyan!
This person was Li Yanyan who had been dissected by them in the dissecting room before!

"How did Sister Yanyan become a general teacher?"

Zhou Zheng was quite shocked, which meant that Li Yanyan had applied for body donation a long time ago.

Because of this, after being dissected and autopsyed, her body was not sent to the funeral parlor for cremation, but was frozen and sent to Jiang Medical University.

For a moment, Zhou Zheng was in a heavy mood, and he couldn't hear the connection process clearly, so he saw people start to disperse.

Zhou Zheng suddenly came back to his senses. He rubbed his forehead, thinking that it might be because of the whole night last night that he was not very energetic.

He walked quickly towards the auditorium against the flow of people, until he came to Han Na.

"Dean Han, I have a question. Is this general teacher a defensive corpse?"
