The twenty or so cases before were just the result of preliminary screening. After so many days of repeated investigations by everyone, many details are basically familiar with, so screening is not difficult!
After a period of comparison of the cases in our hands, 90% of the cases were basically ruled out. In the end, everyone selected three cases that were similar to this case.
Jiang Hao finally began to summarize:
"Let's analyze these four cases. The first one occurred in the [11.5 trash can throw a corpse case] 8 years ago. The victim Chen Cuixian, female, 26 years old, 161cm tall, and weighs less than 90 kilograms.
She was a sanitation worker who found a female corpse in the trash can when she was taking out the trash in the morning. After being examined by a forensic autopsy, there was no sign of infringement on the victim. She had a fatal injury on her body, and there were six knives in other parts of her body.
hurt.
It can be seen that this should be the first time the murderer committed the crime. He was not very skillful in the murder method. Although the person was stuffed into the trash can, the police did not extract fingerprints from her. The murderer should have worn gloves at the beginning."
"The second case occurred 6 years ago [4.14 Development Road Murder Case]. The victim Feng Guangmei, female, 28 years old, 158cm tall and 85 kilograms.
When he was discovered, he was lying in a bloody clothing in the green belt. The items he had left on the scene were not lost. He was hit by three stabs, one of which pierced the alveoli, which was fatal.
If this was also the case of the same murderer, then at this time he had overcome the panic when he first killed someone and made a little more fierce move."
"The third case was the [6.21 Broken Bridge Case] three years ago. The victim Tao Miao, female, 31 years old, 168, and weighs 110 kilograms.
She was followed when she was going home at night, and she was killed by a knife, and her body was thrown under the broken bridge.
Due to the hot weather, the deceased was wearing cool clothes, but there were no signs of infringement on his body. Valuable items such as mobile phones were also left on the scene. Since there were very few clues at the beginning, the case has not been solved yet."
Among the three cases that Jiang Hao told, two of them were earlier, and he found out that they were found by himself. As for one case before, they were ruled out because they were committed in the room and that there were property in the house.
Theft does not meet this characteristic and is therefore excluded.
"The above is what everyone summarized. Through investigation, it was found that, in addition to the recent case, all the victims do not know each other, and social relations are not even together, but they are also
It’s not that they have no common ground, they are all engaged in flesh and blood business.”
As soon as the words were finished, everyone was talking about it. After all, this was a very critical clue:
"Is the suspect their client?"
"Not necessarily, how can Du Fang explain? She has already gone ashore to be a mistress!"
"As the saying goes, cousin is ruthless and actor is unrighteous. Perhaps the murderer has no money and will kill him."
...
Seeing that everyone was getting more and more outrageous, Jiang Hao quickly stopped him and said, "Everyone's guess is also a direction for our next investigation. He does not completely deny this guess. Bai Xiu, what do you think?"
After all, it was Bai Xiu's first time here, and she also heard about the basic situation of the case she just told. At this time, she also wanted to see what she learned in school, a doctorate in psychology.
Bai Xiu, who was named by Jiang Hao, was not embarrassed at all. She knew that she was testing herself at this time, so she sorted out her ideas and said:
"First of all, I agree with Team Leader Jiang's point of view. The murderer of Du Fang's case is indeed a contradictory personality. He does not rob money or lust. The reason why he killed her is more like a sanction, or rather
He was extremely conceited in a way of trial, so he was not worried about the police identifying the victim.
For ordinary passionate crimes, there is evidence everywhere at the scene. The police can basically solve the case within 24 hours, but he started with neatness and deliberately chose the position of the action. Obviously, he was prepared. Therefore, such psychological quality is obviously
This is not the first time that the crime has been committed."
Jiang Hao nodded. Bai Xiu could quickly have some logical relationships in his mind after just listening to some content. He was indeed talented. It seems that it is not incapable of having relationships. If he really didn't have any.
Ability, but in the end, I slapped Zhao Kaijun in the face?
So he gave Bai Xiu an encouraging look and continued to ask: "Is there any?"
"Um!"
Bai Xiu still had a lot of things to say, so he continued to say:
"And the three cases selected now are actually not 100% sure that the murderer is the same person, because the murderer's method of committing the crime has not been formed, or in other words, there is no fixed and distinctive technique.
Therefore, these cases can only be regarded as similar techniques and can be investigated, but we cannot blindly believe that they are the same murderer, otherwise they may fall into a dead end.
But here, we boldly speculate that the murderer is indeed the same person. So, based on these cases, we can boldly assume some of the characteristics of the suspicion:
Judging from the target chosen by the murderer, he should have suffered severe psychological trauma in his heart. It may be that he lost his mother in his early years, or that his mother had an undecisive behavior and was known to him, or that his girlfriend betrayed him. Another possibility is that
I contracted some venereal diseases while visiting prostitution, and I had some thoughts of revenge in my heart."
Bai Xiu was very happy when he saw everyone listening to his analysis carefully. The feeling of accomplishment suddenly came up, and he became more and more excited as he spoke:
"Since the victims have been engaged in special professions, the murderer is unlikely to commit a random crime. Therefore, they must know each other, and to achieve precise killing without leaving any traces, and to observe the surrounding environment,
It is definitely not something that can be decided just by slapping your head, so the murderer should be very familiar with the surrounding environment.
Finally, the murderer chose the sharp blade as the weapon, and most of the victims were sneak attacked from behind. This phenomenon shows that the murderer is not tall and may be killed by a woman.
When he committed the crime for the first time, he chased and stabbed the victim several times. At that time, he didn't know whether the victim could resist him. He was also worried. It was not until he became skillful in the technique that he turned into a knife.
fatal.
Therefore, the murderer should be less than 175cm tall, thin, taciturn, weak social skills, but extremely conceited and very strong self-esteem, which is a typical contradictory personality.
My analysis has been completed, some humble opinions are welcome to criticize and guide you!”
After saying that, Bai Xiu did not forget to bow to everyone, which instantly made everyone's impression of her full. There were bursts of applause at the scene, and Jiang Hao couldn't help but sigh:
It turns out that I studied psychology and grasped everyone's first impression of her tightly.
