After Li Huan finished speaking, Chen Bai frowned. If these three cases were done by the same person, then this person's techniques are constantly improving.
"Bai Hongwei, why don't we find the person who was in charge of these cases at the time? This case is very likely to be a serial murder case."
"OK!"
Bai Hongwei was very fast, and the people from Longpan City and Binzhou arrived quickly.
"Captain Lin, thank you for the hard work of traveling and traveling."
"It's okay. I heard that there was also a murder case involving a car on a rainy night here?"
Lin Tao is in his forties and has been a criminal police captain for twenty years.
"Teacher Qin, I didn't expect you to come too."
Song Anchun was a little surprised. They had cooperated with Teacher Qin on a case before. At that time, Teacher Qin found clues on a calf bone that had become severely bone-white and burned, and finally solved the case.
"Hey, hey, hey! They are working hard, but we are not, right?"
Zhou Xun got out of the car and looked at Bai Hongwei with an unhappy expression.
"Yes, yes, you have worked hard too. People drove hundreds of kilometers from Longpan City to come here. Why are you working so hard here when you only have more than 100 kilometers?"
Bai Hongwei and Zhou Xun have known each other for a long time, so they always talk about anything they have to talk to each other.
"Bai Hongwei, you have a consultant, and I also have a powerful consultant here."
Zhou Xun pointed behind him as he spoke, while Chen Bai was already discussing the case with the man.
"Professor Guan, what do you think of this case?"
"The murderer was very nervous when he committed the first murder, so he had no time to clean up the scene. However, even this time the murderer still did not leave any clues at the scene. And after two years, the murderer committed the crime again. At this time, the murderer has made obvious progress.
.”
As soon as Professor Guan said this, Zhou Xun hugged Professor Guan's shoulders.
"Two professors, I know you are all very concerned about the case, but can you let us in? It depends on the weather, but it will rain soon."
"Yes, yes, let's go in and talk!"
At this time, Bai Hongwei realized that everyone was still standing outside. After everyone sat down in the conference room, Professor Guan patted the girl sitting next to him with his hand.
"Xiao Wang!"
"yes!"
Xiao Wang stood up suddenly. Looking at the nervous look of the little girl, Chen Bai knew that this little girl must have just graduated from the police academy, or was a student who had not graduated from the police academy.
"That's right. We rushed to the scene quickly after receiving the report. I won't go into details of the case, but it is worth mentioning that the murderer was captured by a camera at an intersection while committing the crime."
After the girl finished speaking, she handed a USB flash drive to Li Huan.
"You see, it took the murderer a total of an hour to leave after committing the crime."
Professor Guan said, pointing at the video screen with the laser pointer in his hand.
"The first time the murderer committed a crime was in Longpan City, but at that time the murderer's method of committing the crime was not so clever. He just left the scene after killing. But when he committed the second crime, the murderer obviously improved his skills.
, and even cleaned up the scene after the massage. How are you doing? Do you have any video evidence?"
Chen Bai nodded and asked Li Huan to play the video.
"This video is a candid shot of the deceased in the car. We have analyzed it and found out that the murder weapon used by the deceased this time was a modified gas nail gun. But this time the murderer's modus operandi has obviously upgraded. I watched everything from killing to cleaning up the scene to
It only took about twenty minutes to leave."
After Chen Bai finished speaking, Professor Guan frowned. If this was the case, then the murderer would be more proficient in his crime methods.
"Actually, I have a feeling that the murderer is probably related to us."
"Is it related to us? Consultant Chen, what do you mean?"
Lin Tao was a little confused, but then Zhou Xun answered.
"You mean, the murderer might be a policeman?"
"No, what Consultant Chen means is that the murderer is most likely someone from the physical evidence appraisal or forensic center."
Binhai City has a mature system, and Wu Di and Song Anchun are leaders in this field, so they do not need any help for their work. However, in fact, comrades in many places will do it due to limited skills or lack of such professional equipment.
Seek their help to some extent.
"I'm going to check now!"
Zhou Xun has a quick temper, and when he heard Chen Bai deduced the news, he wanted to investigate first.
"Wait a minute, even if you want to go, you have to come with us! Also, have you investigated the victim's social relationships?"
After Chen Bai finished speaking, a little girl stood up from Longpan City and distributed the case files in her hands to everyone.
"The victims of the first case in Longpan City were a young couple. They had not graduated from college at the time. The boy drove out with his girlfriend in a car, and this happened. In fact, at the beginning of this case
At that time, we investigated it as a robbery and homicide, because the murderer took away the deceased's mobile phone when he committed the crime for the first time, but there was no result afterwards. Later, when we were investigating the social relations of the deceased, we accidentally discovered that the female deceased was being killed.
I had been threatened before because the deceased was working part-time as a model outside of school. Just after one job, the deceased received an anonymous letter."
As the girl spoke, she took out the evidence bag from the file bag and handed it to Li Huan, who scanned it and projected it on the big screen.
"The girl didn't take it seriously when she received the letter, but she didn't expect that the girl was killed not long after."
"God gave you beauty, not to please men. You should let those people see your soul."
Chen Bai looked at the threatening letter in front of him and suddenly thought that Qiao Zhenzhen had received such a letter before.
"Da Binzi!"
When the two letters were put together, Chen Bai immediately saw the problem.
"Chen Bai, what do you think this murderer wants to do?"
Bai Hongwei was a little confused, but before Chen Bai could speak, Professor Guan spoke first.
"Chen Bai, this person does have an extreme sense of feminism."
Chen Bai nodded. In fact, this group is not only here, but in all countries around the world. Most of them will say that they are fighting for the rights of women, but in fact they are just people who want to get something for nothing.
"Zhou Xun, where are you? Did you find anything?"
"Yes, we also discovered this when investigating the social relationships of the deceased."
Zhou Xun said as he also took out a letter from the evidence bag.
"The deceased here is the owner of a beauty store. Because her husband is not at home all year round, he had an affair with a boy in the store. I asked the employees in the beauty store and they all know about this."
Chen Bai looked at the three letters in front of him and intuitively told him that this case was not that simple.
"Chen Bai..."
Mu Bai opened the door to the conference room and was stunned when he saw so many people.
"Say what's going on!"
When Chen Bai saw Mu Bai's look, he knew there must be another case.
"Something happened again!"
It was raining heavily. Chen Bai held an umbrella and looked at the scene in front of him. A man and a woman were dead in the car. Both of them had a dagger stuck in their chests. The glass of the car window was all broken.
"Everyone, what do you think?"
"Copycat crime!"
Almost without thinking, everyone present said this answer in unison.
"Yes, it was a copycat crime. There was a man and a woman in the car on a rainy day. These elements all match, but the car was so messy and the blood stains were not cleaned. It seems that it was not the person who did it."
The social relationship investigation of the deceased soon came out. The female was Liu Ge and the male was Liu Daqing.
"This Liu Daqing is over fifty, but this Liu Ge is only thirty-one years old. Isn't the age gap between the two too big?"
Bai Hongwei was a little confused, but Chen Bai knew that this case had nothing to do with the case they wanted to investigate, so it must be resolved quickly now.
"Actually, this case is also simple. It is a simple case of hiring a murderer to kill someone."
"What?"
Everyone was a little surprised. There was no investigation yet. How could Chen Bai be sure that this was a murder-for-hire case?
"It's very simple. We first looked at the scene. There was a lot of blood in the car, but the main blood stains were on the driver's seat and passenger seat of the car. But when we found the deceased, they were in the back seat. This is because the murderer wanted to imitate
In the previous case, judging from the location of the knife on the two chests, someone should have suddenly blocked them back in the car when they wanted to get out of the car. And judging from the fact that the two people did not struggle, it is very likely that they were
Surprise attack."
"But even if that's the case, how can we judge that the murder was a paid crime?"
Lin Tao was a little puzzled, but Chen Bai didn't explain much at this time and just asked Li Huan to announce his investigation results.
"According to the investigation of Liu Ge's social software, a week ago Liu Ge had added a person who called me Brother Dashui. Afterwards, Liu Ge transferred Wugan to that person and asked them to kill Liu Daqing."
"Liu Ge's beauty shop was opened by Liu Daqing with money, and Liu Daqing also has dozens of shops that can collect rent under his own name. This old couple must not have any feelings. Liu Ge married
Liu Daqing is probably doing it for Liu Daqing’s money.”
After Chen Bai finished speaking, Li Huan continued.
"And the clerk at the beauty store who has always been confused with Liu Ge is named Li Sen. He just graduated from college this year. We found out that just this morning, Li Sen withdrew 16,000 yuan from Liu Ge's bank card.
Yuan."
"Let's go, let's go find this Li Sen first!"
Things are different now. It is much easier to find someone than before, so everyone quickly found Li Sen.
"Li Sen, if you tell the truth now, you can still get a chance to survive, but if..."
"I said, I said!"
Before Chen Bai finished speaking, Li Sen explained what happened. It turns out that Liu Ge and Liu Daqing were together just for money, but Liu Ge is very smart. She knew that she would definitely want Liu Daqing's money.
They couldn't wait until Liu Daqing died, so Liu Ge thought of a way, which was to find his sweetheart. The two planned to find someone to kill Liu Daqing. Anyway, Liu Ge and Liu Daqing were also legally married now, so Liu Daqing's property
They must all belong to Liu Ge.
"Is this the person you are looking for?"
Chen Bai said and took out Liu Ge's mobile phone. Li Sen nodded and confirmed that the person was the killer hired by himself and Liu Ge.
"Okay, you are quite honest, we can arrest you now."
Of course, since these people dare to kill people, they must not be simple characters, so everyone also formulated a simple arrest plan.
"What? You really don't need our help?"
Zhou Xun was a little worried. Although this case had little to do with them, they could help if they could.
"No, we can do it ourselves!"
Chen Bai smiled and declined. It would be such a waste if they needed help for such a thing.
"Okay, then let me see what you are capable of!"
Zhou Xun and Lin Tao are actually very curious. They have heard that the Binhai City Criminal Investigation Detachment is a group of people with extraordinary abilities. They haven't seen anything else yet, but it only took less than three hours from seeing the scene to finding the murderer.
This is still very impressive.
"Then we'll just watch from the sidelines!"
The killer Li Sen was looking for was named Huang Zhiqiang. He had been in prison for robbery before. After he was released, he had been watching the scene in a KTV. What Chen Bai and others discussed was that Bai Hongwei and others would pretend to be property personnel to check whether there were leaks in the house.
, enter the house directly after opening the door and arrest.
"The other parties are people with lives on their hands, so everyone should be careful."
At six o'clock in the afternoon, it is time to get off work. The reason why we chose to arrest at this time is to make Huang Zhiqiang relax his vigilance. Of course, on the other hand, it is also because we can take advantage of this time to avoid the presence of a few more cars in the community.
be found.
"Teacher Qin, are we really looking at you like this?"
"Don't worry, they can solve it."
At this time, Bai Hongwei had already led people upstairs, while Chen Bai stood at the door of the building, lit a cigarette, and waited leisurely.
"Aren't you going up?"
Professor Guan came to Chen Bai. Chen Bai took out his cigarette case and Professor Guan waved his hand.
"No, just leave such small things to them. I can advise you. I don't have a gun or a body armor. I'm still not suitable to go up at this time."
Professor Guan nodded, and Chen Bai thought for a while and asked.
"Professor Guan, based on these cases, what kind of psychology do you think the murderer has?"
"The murderer specifically picks this kind of person. There may be two reasons. One is the extreme hatred for this kind of person. The murderer may have been betrayed by his partner, or his partner was caught doing this kind of thing.
This is one possibility. Another possibility is that the murderer himself was once a lonely person. After he did such a thing, he regretted it very much. He might even be caught committing an act.
, this sense of humiliation has always been with him. Under the strong sense of humiliation, this person had a psychological change and committed murder."
While the two were talking, a man suddenly ran down from upstairs. This man just looked at Chen Bai, and Chen Bai knew that there was definitely something wrong with this man.
"Stop!"
The umbrella in Chen Bai's hand stabbed directly, and the man was knocked down before he could defend himself. Just as he was about to get up, Chen Bai side-kicked his chin, causing the man to faint immediately.
"Not bad at all!"
"I also graduated from the police academy!"
After bringing everyone back to the police station, Chen Bai immediately started the interrogation. Basically, without any effort, these people all confessed.
"Comrade police, I have important clues to report!"
Huang Zhiqiang knew that as long as he could tell some useful clues for them at this time, it would definitely be better than telling nothing at all.
"explain!"
"That's right, we still have one online..."
According to Huang Zhiqiang's explanation, they also had an upline who had been engaged in some illegal pornographic transactions for a long time, but this person was of no use to Chen Bai and the others, so Chen Bai directly handed Huang Zhiqiang over to Mu Bai.
"The problem now is still this case. We have now identified the murderer's weapon, and we basically know that the murderer came for the couple having a tryst in the car, but they still cannot identify the murderer."
In the conference room, Chen Bai and others were still watching the live video. At this moment, Teacher Qin suddenly asked a question.
"In the previous killings, the murderer directly broke the car window, but why did the murderer not only fail to break the car window this time, but instead lowered the car window on his own initiative?"
After Teacher Qin finished speaking, Chen Bai and Professor Guan also fell into thinking. The car windows would not automatically lower themselves without anyone operating them, but they did lower themselves at the scene of the crime. This also gave the murderer an opportunity to take action.
Opportunity.
"Actually, in addition to this problem, there is another problem that I have never been able to figure out."
After Chen Bai finished speaking, he took out the case files of the previous two cases.
"In the first two cases, the murderer used a hammer to smash the car window before committing the crime. Generally speaking, people who commit serial murders have strong labels, and they will never change their modus operandi.
But why did the murderer use an air nail gun to kill this time?"
After Chen Bai finished speaking, Professor Guan also added from the side.
"Yes, in fact, I have been thinking about this issue. The murderer probably had no experience in committing a crime for the first time, but even so, the murderer still used his strong anti-investigation ability to erase his traces, and the second time
The murderer showed obvious improvement the first time and quickly cleaned up his traces after the murder, but I also wonder why the murderer used a different weapon when he committed the crime for the third time."
While the three of them were thinking, Professor Guan suddenly noticed that when the murderer was cleaning up the scene, his raincoat was accidentally photographed, and there seemed to be some writing on the hem of the murderer's raincoat.
"Chen Bai, look here!"
Professor Guan pressed pause on the video, pointed at a place and said.
"Can you tell what the word is?"
Chen Bai squinted for a long time, but he couldn't see clearly what the words were.
"Li Huan, can you still sharpen the video to be clearer?"
"Brother, this is really my limit. The most I can do is sharpen the video like this. But I do know someone who is quite good at this kind of video sharpening."
