The little catcher in the police station

"Just passed, so I thought of going to the grassroots to exercise, and combining theory with practice can improve myself!"

It is true that a lot of knowledge can be learned from books, but knowledge that is divorced from reality will become empty talk in the end, which will only make people laugh.

"Yes, it seems that your opportunity has come. I just joined the team today to take you to learn about a special case."

Hearing what Jiang Hao said, Bai Xiu immediately became interested: "Is there already a case?"

"Well, you'll know by then!"

Thinking that she will soon be able to get in touch with real case handling, Bai Xiu is both worried and somewhat looking forward to it.

After all, she didn't come to be gilded, but she really wanted to go to the grassroots level to practice.

"Huh? Xiao Jiang, have you brought your apprentice?"

When Jiang Hao walked into the office with Bai Xiu, Wang Shaodong immediately cast glances back and forth, making Bai Xiu a little embarrassed.

"Let me introduce, this is a new member of our special case team, named Bai Xiu, a psychological tester, and this is the captain of the Criminal Investigation Brigade, Wang Shaodong!"

"Hi Wang Dui, my name is Bai Xiu, please take care of me."

Bai Xiu followed Jiang Hao and introduced herself to everyone.

"Okay, we are short of a psychological profiler here, and it's time to come, please take a seat!"

Even though it was Wang Shaodong's Criminal Investigation Brigade, it didn't have the luxury of being equipped with a psychological profiler.

Although the Western world has already used criminal psychology to solve crimes more than 100 years ago, it has only been 30 years since this concept was introduced to China, and its development is not very mature.

But who doesn't like these profilers who can analyze the suspect's behavior, motivation, psychological characteristics, etc. based on some details of the case?

Finally, the police identified the real culprit based on the description of the suspect's psychology and image drawn by the profiler.

Once this kind of news is reported, it can cause a great sensation, making everyone feel mysterious about this profession, and also have an inexplicable preference.

Seeing that Bai Xiu is a psychological profiler, Wang Shaodong immediately became interested.

"I have just graduated with a Ph.D., and I still have a lot to learn from all the seniors here."

Bai Xiu hurriedly said modestly.

"By the way, how is your investigation going? I'm done!"

Jiang Hao has not forgotten the purpose of his visit today, and the three cases he investigated are all completed, it is time to summarize and analyze!

"It's coming to an end, but it doesn't affect our progress."

"Okay, then let's find the common ground first. Based on the characteristics of the Hanjiang female corpse case, I have summarized the following points. Let's study it together. If I have missed anything, you are welcome to add it!"

As the leader of the expert team, Jiang Hao was already the actual leader of the case, so he did his part to guide everyone into his analysis.

And Bai Xiu was new to this case, so she took out her notebook seriously and recorded it.

"First of all, the murderer does not rob money or sex. From the fact that he does not touch any of the victim's belongings, we can see two points. The first point is that he only wants to kill the victim, and the second point is an implicit condition. The deceased had her ID in her bag, which means the killer didn't mind, the police knew the identity of the deceased."

"Wait a minute, I have a question."

When Jiang Hao said this, a police officer below immediately raised his hand to question.

"Speaking!"

"You said the murderer didn't mind us discovering the identity of the deceased, but in fact, we didn't know the identity of the deceased at first, and we only found out through her lover Tang Zhenhua, so how can you just infer that the murderer doesn't mind?"

"Very good, please sit down!"

Jiang Hao originally thought that this inference was easy to come by, but he didn't expect that some people still couldn't understand it. He thought it was easy, but that was just his thought, and it didn't represent everyone.

So, he decided to be more specific:

"Indeed, when we found Du Fang's body, there was no Bao Bao at the scene, because the body was taken to another place by the current, and during this process, Bao Bao unfortunately sank to the bottom of the river.

Afterwards, the salvage team salvaged the bag, and the valuables in the bag were not lost, which also proved my judgment.

Even if Tang Zhenhua's confession is not passed, we will soon be able to find the ID card in the salvaged bag and know the identity of the deceased, so I have my inference. Is there any problem? "

Seeing everyone shaking their heads, Jiang Hao finally concluded: "So, the first feature is that the murderer will not intentionally hide the victim's ID information, and he will not be greedy for money."

With this one condition, the vast majority of cases can be screened out. After all, there are not many cases that do not rob money or sex, and do not hide the corpse.

"Next, the second commonality is sharp instrument injury. After forensic dissection, the sharp instrument pierced the body by ten centimeters and forced the main artery. Even if Du Fang was not drowned, he would have died of excessive blood loss later.

It is not difficult to see from this that the murderer has a certain amount of research on the structure of the human body, and he shot decisively, killing him with one blow, unlike a novice.

So I guess, he must have killed people like this before, and he has overcome the fear in his heart, so that he will not hesitate when things are imminent. "

"According to the above points, let's take a look at the cases in hand, see if there are any that meet the above characteristics, and if there are any, let's discuss them together!"

After Jiang Hao re-emphasized the distinctive features of [2 Hanjiang Female Corpse Case], he looked at everyone.

Chapter 778 Bai Xiu's First Show

The twenty or so cases before were just the results of preliminary screening. After so many days of re-investigation, everyone was familiar with many details, so the screening was not difficult!

After comparing the cases in everyone's hands, basically [-]% of the cases were 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 happened eight years ago [8 Garbage Dumping Case]. The victim, Chen Cuixian, was 11 years old, 5cm tall and weighed less than 26 kilograms.

She was a female body found in a trash can by a sanitation worker when she was taking out the trash in the morning. After a forensic autopsy, the victim showed no signs of being violated. She had a fatal wound on her body and six other knives in other parts of her body. hurt.

It can be seen that this should be the murderer's first crime. The method of killing is not very skilled. Although the person was stuffed into the trash can, the police did not extract fingerprints from her body. The murderer should have worn gloves at the beginning. "

"The second case was the [6 Kaikai Road Murder Case] ​​that happened six years ago. The victim, Feng Guangmei, was female, 4 years old, 14cm tall and 28kg in weight.

When he was found, he was lying in a bloody suit in the green belt. All the belongings left at the scene were not lost. He was stabbed three times, one of which pierced the alveoli, which was fatal.

If this is also the case committed by the same murderer, then at this time, he has overcome the panic when he killed the first time, and his shots have been sharper. "

"The third case was the [3 Broken Bridge Case] ​​three years ago. The victim Tao Miao, female, was 6 years old, 21cm in height and 31kg in weight.

When she came home at night, she was followed by someone, she was stabbed to death, and her body was thrown under the broken bridge.

Due to the hot weather, the deceased wore cool clothes, but there was no trace of violation on his body, and valuables such as mobile phones were also left at the scene. Since there were few clues at the time, the case has not been solved yet. "

Among the three cases mentioned by Jiang Hao, two were relatively early, and he investigated it himself. As for the previous case, he ruled it out because it was a case of burglary and property in the home was confiscated. Pirates do not meet this characteristic and are therefore excluded.

"The above is the situation that everyone has concluded. Through the investigation, it was found that, together with the recent case, all the victims did not know each other, and the social relationship was not the same. However, they also It’s not that they have nothing in common, they’re all in the flesh business.”

As soon as the voice fell, everyone immediately talked about it. After all, this is a very crucial clue:

"Is the suspect their client?"

"Not necessarily, how does Du Fang explain? She has already gone ashore to be a mistress!"

"As the saying goes, a cousin is ruthless and an actor is ruthless. Maybe the murderer has no money, so he will kill him."

……

Seeing that everyone was talking more and more outrageous, Jiang Hao quickly stopped and said, "Everyone's guess is also a direction of our investigation. I don't completely deny this guess. Bai Xiu, what do you think?"

After all, Bai Xiu came here for the first time, and she also heard the basic situation of the case she just described, so she wanted to see what she, a doctor of psychology, had learned in school at this time.

Bai Xiu, who was named by Jiang Hao, was not at all embarrassed. She knew that she was testing herself at this time, so she sorted out her thoughts and said:

"First of all, I agree with Team Leader Jiang's point of view. The murderer in the Du Fang case is indeed a contradictory personality. He didn't rob money or sex. The reason why he killed her was more like a sanction, or A method of trial, he is extremely conceited, so he doesn't worry about the police identifying the victim.

As for ordinary crimes of passion, evidence is everywhere at the scene, and the police can basically solve the case within 24 hours, but he strikes cleanly, and the location of the shot is also deliberately missed, obviously prepared, so such psychological quality, obviously This is not the first time a crime has been committed. "

Jiang Hao nodded. Bai Xiu just listened to some content, and she could quickly get some logical relationships of the cases in her mind. She indeed has some talent. It seems that she is not incapable of making connections. Ability, didn't he slap Zhao Kaijun in the face in the end?

So he gave Bai Xiu an encouraging look, and continued to ask, "Is there any more?"

"Ok!"

Bai Xiu still had a lot to say, so she continued to say:

"As for the three cases selected now, we cannot be [-]% sure that the murderer is the same person, because the murderer's modus operandi has not yet formed, or in other words, there is no fixed and distinctive method.

Therefore, these cases can only be regarded as similar methods and can be investigated, but one cannot blindly believe that they are the same murderer, otherwise they may fall into a dead end.

But here, we boldly guess that the murderer is indeed the same person. Then, based on these several cases, we can boldly assume some characteristics of the suspect:

Judging from the target chosen by the murderer, he should have suffered serious psychological trauma. It may be that he lost his mother in his early years, or his mother's indecent behavior was known to him, or his girlfriend betrayed him. Another possibility is I contracted some sexually transmitted diseases when I went to prostitutes, so I had some thoughts of revenge in my heart. "

Seeing that everyone listened to her analysis seriously, Bai Xiu felt very happy, and her sense of accomplishment immediately came up, and she became more and more enthusiastic as she spoke:

"Since the victims have all engaged in special occupations, the murderer is unlikely to commit the crime randomly. Therefore, they must know each other. To achieve precise killing without leaving traces, it is necessary to observe the surrounding environment. It's definitely not something that can be decided immediately, so the murderer should also be very familiar with the surrounding environment.

Finally, the murderer chose a sharp blade as the murder weapon, and most of the victims were attacked from behind. This phenomenon shows that the murderer is not tall, and there may be a possibility of being killed by a woman.

When he committed the crime for the first time, he chased after the victim and stabbed him several times. At that time, he didn't know whether the victim could resist him. fatal.

Therefore, the murderer's height should be under 175cm, thin, reticent, and weak in social skills, but extremely conceited and very strong in self-esteem, which is a typical contradictory personality.

My analysis is over, and I have some humble opinions. Welcome everyone to criticize and guide! "

After finishing speaking, Bai Xiu didn't forget to bow to everyone, instantly filling everyone's impression of her.There was bursts of applause at the scene, and Jiang Hao couldn't help sighing:

As expected, she studied psychology, so she made everyone's first impression of her very accurate.

Chapter 779 Working Overtime Tonight

Bai Xiu clearly knew that since she was a newcomer, she had to lower her posture and be more well-behaved, so that she could easily blend into this strange environment.

After all, who would refuse a modest and lovely beauty school bully?

Amidst the applause, Bai Xiu sat back down again, then looked at Jiang Hao, and found that he also nodded affirmatively to herself, and she was overjoyed.

Now you know I'm great!

indeed,

After Jiang Hao listened to Bai Xiu's analysis, he also felt that something became clear.

Even he didn't pay attention to some details.

Well, this doctor is not in vain!

"That's right, Xiao Jiang, it seems that your expert team is really full of talents, and they are all young people. It's really the waves behind the Yangtze River pushing the waves ahead. We, the waves ahead, can only be photographed on the beach by you!"

Wang Shaodong couldn't help applauding at this time. Bai Xiu was able to deduce the basic situation of the murderer through these details just based on the clues she just learned. Such an ability is indeed beyond the reach of ordinary people. .

As expected, a psychological profiler has two brushes.

"Ahem, Captain Wang, is it a joke that our expert team is short? Our top priority now is to find the suspect first and bring him to justice!"

Jiang Hao didn't answer the conversation, but instead changed the topic and brought his attention back to the case itself.

"Yes, with the full cooperation of your expert team this time, I believe we will be able to find new clues soon."

Perhaps because another psychological profiler came, Wang Shaodong's confidence in solving the case was strengthened again.

"Then today's analysis meeting will come here first. We will divide into four teams this time. Based on the characteristics of the suspects that Bai Xiu just mentioned, in these four cases, we will search their interpersonal relationships on a large scale and find people who meet these characteristics. .”

Jiang Hao finally summed it up, and then took the lead in picking the first case, which was regarded as the responsibility of their expert team, and the other three cases were handed over to Wang Shaodong and the others.

After everyone clarified the mission, they began to split up.

Jiang Hao took all the files of the [11 Trash Can Throwing Corpse Case] ​​and began to sort out possible suspects.

"Bai Xiu, let's go, let's go too!"

As soon as he got in the car, Jiang Hao saw that she was wearing a police uniform, so he asked, "Do you have casual clothes?"

"Um, yes, do you need to change into casual clothes?"

Bai Xiu had heard before that when criminal police officers handle criminal cases, they usually wear casual clothes most of the time, and they seldom drive police cars out to handle cases.

"Yes, go back and change. From now on in our expert group, most of the time will still be casual. We are not on TV, so we don't need to dress properly."

"Okay, team leader, please take me back to the dormitory, so I can change my clothes."

After Jiang Hao sent her back to the dormitory, he waited in the car for a while, and at the same time he was sorting out his thoughts. He was following up this case in the early stage, and he knew a lot about it.

Therefore, from the previous understanding, he did not find that the kind of person that fits Bai Xiu's speculation, but either Bai Xiu's speculation was wrong, or the other party was hiding very deeply, and his level of digging could not find him out. .

In short, no matter which possibility it is, he has to try it one by one to know. After all, eight years have passed, and he still needs to use the elimination method he is good at to thoroughly investigate.

While Jiang Hao was thinking, Bai Xiu came over after changing her clothes. Without the foil of the police uniform, she instantly transformed into a student girl. She was wearing a plain top, paired with a pair of jeans, and simply put on some lip gloss. The overall look is refreshing and refreshing, very academic style!

"How would I look in this suit?"

Bai Xiu stood in front of the car window and asked Jiang Hao in the car. After all, it was her first time participating in an action, so she didn't know how she would dress like this.
