Cheng Wenming has been serving as the deputy detachment of the criminal police for all these years since his legs regained consciousness.

Although he has an administrative position, he rarely cares about the work in management, and he is single-minded in studying, guiding, or directing the investigation of major criminal cases in the city, especially the leader of the detachment, and it is better to say that he is a criminal policeman with a higher administrative rank and police rank.

He has a specialization in the art industry, and he is definitely a good hand at pondering difficult cases.

There was so much truth in his analysis that he was almost misled by him.

Li Jiaqi mentioned the current head of the criminal police detachment for the second time, Han Bo realized that he was a little preconceived, picked up the case materials again, looked at them carefully for nearly ten minutes, and suddenly raised his head: "Lao Cheng, you are all old criminal policemen, you should have seen the crime scene investigation technology, one of the classifications of the scene is the first scene, the second scene and the third scene."

The first scene refers to the scene where the deceased was killed, and the second scene is the scene where the body is dismembered or dumped. If there is no dismemberment, then the scene of the body is the second scene, and if there is an act of body dismemberment, then the scene of the body is the third scene, because the third scene is often scattered when the body is decomposed.

Your previous inferences were made on the basis of determining that the place where the body was found was the first scene, that is, the murderer took the little girl to a small park to commit the crime, not the small remote park in the Nanzhou district where the murderer committed the crime in the urban area and then moved the body. These two conclusions are two conclusions of completely different nature, which directly determine the direction of the investigation of the case!"

The old leader's remarks were exactly the same as those of his immediate boss at the case analysis meeting.

The reason why the task force does not pay attention to the speculation that acquaintances committed crimes is that they believe that the small park is the scene of the dumping of corpses (the second scene).

Cheng Wenming trusted his instincts and stopped talking.

Although Wang Jiefang participated in the investigation, he was not a member of the task force, so he was not very easy to express his opinions, so he lit a cigarette and remained silent.

Li Jiaqi went out of the scene and examined the body of the murdered little girl, and had a certain right to speak, so she couldn't help but say: "Han Ju, it is not easy to transport a corpse from the city to a small park, although the girl is not tall and weighs not too heavy, at least we found no traces of throwing the body at the scene." ”

"The point is, again, there is no evidence that the small park is the first scene!"

Han Bo held up the case file and said very seriously: "Although there have been cases of acquaintances committing crimes and covering the victim's face when committing crimes, this situation is indeed not universal. Especially in the case of having the DNA information of the murderer, having checked the social relationship between the victim and the victim's parents, and almost ruling out the possibility of acquaintances committing the crime, if I were the head of the task force, I would not agree with your point of view. ”

"Han Bureau, but I think it may really be an acquaintance who committed the crime!" Cheng Wenming realized that he could no longer be silent and insisted on his opinion again.

"You are an old detective, experienced, I trust your instincts, trust your judgment. But this is solving the case, not anything else, and it is necessary to speak with facts, not just trust between individuals. ”

Han Bo put down the materials, flipped out a few photos taken during the scene investigation, and said meaningfully: "The nature and motive of the crime have been determined, you should conduct in-depth and detailed research on the crime scene, capture the clear traces of the scene, dig out shallow information, find and collect all the clues that the murderer may have left, and then verify your speculation." ”

"There was hardly any trace of the site other than the cremation. Li Jiaqi couldn't help but interject again.

To everyone's surprise, Han Bo suddenly smiled, looked at Li Jiaqi with a smile and said, "Jiaqi, you are a person who has been married and had children, or a forensic doctor, not a little girl who doesn't know anything. If you can find the branches or leaves stained with sperm spots, and can confirm that the *** extracted from the genitals of the murdered girl is left by the same person, then it can prove that the small park is not the scene of the dumping of the body, but the first scene. ”

Not everything can be "put away freely", such as ***!

Not to mention that the murderer will be very nervous when he rapes, that is, an ordinary person will have *** overflow after passion under normal circumstances.

What's more, if the body is dumped, the murderer will not be able to blatantly carry or carry the body to the small park, and will definitely carry it in a bag or other things. In other words, if the murderer*** can be detected from the branches or leaves at the scene, it is unlikely that it will naturally spill from the body of the little girl who was killed.

Li Jiaqi's face turned red, and she subconsciously raised her hand to cover her mouth.

Zhou Suying was also embarrassed, and hurriedly stopped pretending to watch the projection.

Wake up the person in the dream with a word, Cheng Wenming's eyes lit up, and he said excitedly: "Why didn't I expect it, Han Ju, you have helped me a lot, I will let Fang Hailong inspect the branches and leaves collected from the scene!"

"This is the authorities' obsession with bystanders, so when investigating some difficult cases, you must not drill the horns," Han Bo smiled slightly, and pointed to a stack of photos in his hand: "The scene is well protected, which is worthy of praise." If you hadn't collected the branches and leaves at that time, even if it was stained with the murderer's sperm, you wouldn't have had a chance to verify it now that you think about it. ”

This is not as simple as the authorities are obsessed with bystanders, and they have invited several criminal investigation experts, aren't they bystanders?

The old leader definitely has a way to solve the case, and Zhou Suying couldn't help but quip: "Han Bureau, you're not praising us, you're praising yourself." ”

"Praise myself, I'm not that arrogant. ”

"I'm not kidding, you're really praising yourself, these rules to protect the scene were set by you back then, and we have been following the rules, isn't this praising yourself?"

"What I set was required by my superiors! When it comes to rules, there are many rules and regulations, even if they were set by me back then, the key lies in their implementation. Han Bo didn't want to brag about himself, signaled Cheng Wenming to be busy, and got down to business: "To investigate the social relationship of the victim, not only to investigate the social relationship in the real world, but also to check the virtual world, whether the victim has a QQ number, whether he usually goes online, whether he has made netizens, these situations must be clarified." ”

The old leaders are all deputy bureau chiefs, thinking that he will no longer participate in the investigation of specific cases when he becomes a big leader, and thinking that his current job is to listen to reports and give instructions, but I didn't expect it to be so powerful.

Wang Jiefang was full of emotion, ashamed of himself, and said embarrassedly: "I checked, there is a QQ number, which is full of classmates, and no unknown netizens have been found." ”

"Where did you find it?"

The school did not allow students to bring mobile phones, and her parents were worried that playing with mobile phones would affect their studies, so they did not buy her mobile phones. But someone in the same class secretly brought a mobile phone with her QQ number on it. ”

"What's the use of just registering an account, how does she usually go online?"

"Sometimes I borrow my classmates' mobile phones and have time to go to Internet cafes with my classmates, and the security department has punished them for the Internet cafes opened by minors. In addition to borrowing classmates' mobile phones and going to Internet cafes, during holidays, especially winter and summer vacations, I use my home computer to surf the Internet with the permission of my parents. ”

"How can you confirm that she only has a QQ number, what if the second one. ”

"Han Bureau, we considered the possibility that she made netizens and was brutally killed by netizens, and the technical detectives and Internet police checked her home computer and found no traces of other QQ account logins. ”

Han Bo groaned: "Dad is in business, Mom works in the Second Courtyard of the city, just a baby daughter, the usual pocket money, the New Year's money should not be less, if she likes to surf the Internet and like to chat QQ, it is entirely possible to secretly buy a mobile phone and secretly run a mobile phone number." ”

"It's possible, the key is that no one has seen it, and I haven't found it at her house. ”

"When I was in school, there was a female classmate in the class who liked to make small reports, and she would poke her ass at the teacher, and I believe you also encountered it when you were in school. Mobile phones are just like the villain books we read at that time, they will be confiscated if they are known by teachers, and it is also troublesome for parents to know. Judging from these materials, the victim is precocious, and it is entirely possible to secretly buy a mobile phone and not let others know, and then check to see if she has it. “

"Okay, tell Lao Cheng later, and let Lao Cheng arrange someone to investigate. “
