Han Chen stood under the lamp, his jacket was unbuttoned, and his shoulders were wide and waist narrow, and his legs were slender. His expression was very calm, but with a bit of the usual indifference, not like smiling Yan Yan like when he and Jin Xi were alone.
"The age and appearance of the suspect are not assumed. But he was able to carry a 50-60kg body from the road to the forest with his bare hands, and he paid attention to not leaving any obvious footprints and marks, indicating that he did it very easily. Therefore, he It should be a strong, strong grown man."
When Jin Xi heard the first sentence "Don't assume age group and appearance", the corners of her mouth curved. This man... on purpose!
But when she heard the back, she suddenly fell into a trance. She found that Han Chen, who was engaged in traditional criminal investigation, had a different brain circuit than hers. He's really good at capturing the logic hidden in the details and drawing conclusions that don't coincide with hers, but make sense.
Han Chen continued: "Secondly, the suspect showed adept and stable crime-killing skills, and this is definitely not the first time he committed a crime. Therefore, we have searched the city for information on unsolved homicides and disappearances in the past five years. , found that there were similarities in four cases. Because the time interval was long, they were distributed in various sub-bureau areas, and some bodies were not found, so they were not reported to the provincial department in the form of serial killings by the sub-bureaus.”
The criminal police officers in the audience were in an uproar, and Jin Xi was also slightly startled.
She understood what Han Chen said. If only four crimes have been committed in five years, the time and place are scattered, and the high-IQ murderer must have various cover-ups, it is indeed possible to escape the attention of the police and not link these cases together.
But Han Chen is such a keen person. With these three cases for comparison, it is easy to grasp the clues of the past and establish that the same person committed the crime, right
This also means that the number of people killed by "he" may reach 7!
"In the current three cases, no valuable surveillance footage and witnesses have been found. However, we will immediately expand the search area and search for the archives of the previous four cases." Han Chen said.
The criminal policemen nodded frequently, but Jin Xi secretly sighed.
Han Chen's trick sounds simple, but it works! By inference, the face for him to collect evidence suddenly expanded. You haven't been photographed for the three crimes you committed, but what about the four pushes forward? Can you guarantee that there will always be no mistakes? Especially in the early committing crimes, even if he is a criminal with a high IQ, he is rusty and is likely to leave loopholes.
And as long as Han Chen finds one of the loopholes and clues, can he find someone out of nowhere
Thinking of this, Jin Xi, as a person from the criminal psychology school, suddenly felt a little sad.
She talked so much, drew so much, racked her brains to quote scriptures, and reasoned and analyzed rigorously, so that she could outline all aspects of the suspect. How easy is this? But maybe Han Chen will throw out a surveillance video at that time and capture the person directly...
She raised her head and looked at him on the stage.
In this way, maybe he can really find the murderer faster than her.
... Men who engage in traditional criminal investigation are really annoying!
"Thirdly, according to the analysis of the injuries on the victim's body, he must have suffered long-term abuse before death. Therefore, the suspect needs an independent residence to carry out the abuse and killing. After the victim's death, a large amount of water is needed to wash off the blood on the ground, and the Prevent blood from seeping in. So if he lives in a building, it must be on the bottom floor.
The deceased must have screamed for a long time before he died, but in the autopsy report, no traces of tape or cotton were found on his face and throat. It shows that the sound insulation of the suspect's residence is very good. Even a villa will have neighbors around. Therefore, he either lives alone in a remote suburb; or he has made special modifications to the room. It will not be other noise disguise, as that would easily lead to complaints from neighbors.
Screening the data of all remote independent houses in the suburbs of the city; screening the engineering data of the first floor or the negative first floor undertaken by the decoration company in the city within three months before the first case occurred five years ago. The requirements of suspects must be very high, which are different from those of ordinary people. The decoration company will definitely be impressed by him. "
The detectives under the stage were quiet and listened attentively. Jin Xi is also thinking: Yes, the deceased was not silenced, but he would definitely scream when he was abused. This is probably the "logical paradox" that Han Chen said before. A very subtle point, but it is these small paradoxical points that point to the truth.
She actually wanted to stand up and say: It must be a converted villa! Because according to the suspect's portrait, how could he live in a wilderness hut. But thinking about the traditional criminal investigation genre like Han Chen, it must be rigorous enough not to let go of any small possibility. Well, okay, the big deal is to turn around and persuade him to search the villa first.
"Fourth, one of the important physical evidences in this case is the nurse's uniform. These three sets of nurse's uniforms are exactly the same in size and style, and they are new after preliminary testing and have not been washed. Compare the nurses' clothes, try to identify the manufacturer, and then find out the source of purchase. This is what we have at present."
At this time, a criminal policeman asked, "Team Leader Han, are the three handbags that Bai Jinxi mentioned just now also important evidence?"
Jin Xi also stared at him intently. Yeah, not to mention the tote bag, such an important thing.
As a result, he pondered for a while, and replied: "Handbags are expensive, we found shopping receipts at the homes of the three victims, and also retrieved videos from shopping stores. They were all alone or with female friends. I went to buy a handbag, and the time, style, and place of purchase are different. At present, there is no correlation. Therefore, it is not a key detection direction at this stage. "
Everyone heard it clearly, but Jin Xi was also a little disappointed. Because as a "souvenir", she also expects to dig out more clues from the handbag, such as all red bags, all GUCCI bags. But now it seems that the suspect simply took the souvenir, which is indeed not of much criminal investigation value.
Just as she was thinking, Xiao Zhuan, who was beside her, suddenly approached with admiration and said in a low voice, "Xiao Bai, your boyfriend is really amazing!"
Jin Xi smiled slightly, glanced at him, and asked, "Then who do you think is better between me and him?"
This question really made Xiao Zhuan embarrassed. He thought about it and replied, "It's not the same. Your reasoning sounds exciting! But the boss's reasoning... listens to calm people's hearts."
Jin Xi was stunned, looked at him, remained silent for a moment, and finally said, "Xiao Zhuan, what you say sometimes... it really doesn't look like you said it."
Xiao Zhuan was stunned before he reacted, with a happy expression on his face: "What is it? This sentence is very profound, isn't it!"
