Since Zhang Xiuwen and Wang Yuan'e are uncles and sisters-in-law, she was naturally surprised when she knew that Zhang Pei bought *** for Wang Yuan'e. At the same time, the relationship between the two was tense, so Zhang Xiuwen didn't want to mention a word about Wang Yuan'e in front of Zhang Pei.

Ma Hongwen quickly sorted out the reason why Zhang Pei said that the two "definitely don't know each other".

At the same time, the investigators also provided other important clues.

After a technical appraisal of the indoor environment where Wang Yuan'e lived, and found that there were no traces of outsiders entering or leaving, Ma Hongwen instructed some case-handling personnel to continue to investigate outdoor clues, that is, to continue the investigation in the community where Wang Yuan'e lived, trying to confirm whether there were any suspicious people entering and leaving Wang Yuan'e's house on the day of the crime.

In Ma Hongwen's view, there is always the possibility of "artificially made" traces at the scene, but it is unlikely that the outdoor clues will be artificially altered.

According to the autopsy, Wang Yuan'e died at about 3:30 a.m. Because the case happened too late, during the household visit, the residents of the community said that they fell asleep at the time, and they didn't see it and didn't know if anyone had entered or left Wang Yuan'e's house.

The community where Wang Yuange lives is not low-grade, and monitoring equipment is installed. However, in 2008, the monitoring network was not perfect, and only the people entering and exiting the gate of the community could be seen from the monitoring, and each unit building could not be observed in detail and specifically.

However, through the surveillance video, as long as someone appears for a period of time before and after the crime, even if it only appears at the gate of the community, this person is also suspected of committing a crime. In the middle of the night, at the time of the crime, everyone else was sleeping at home, but you appeared at the gate of the community not far from the scene of the crime, who is suspicious if you are not suspicious?

Soon, the investigators found a man who came out of the community in the surveillance video. What surprised the investigators even more was that although the picture at that time was pitch black and the man's face could not be seen clearly, under the illumination of the headlights at the entrance of the community, the surveillance video clearly captured the license plate number of the vehicle on which the man was on.

According to the license plate number, the investigators quickly tracked down the man.

After investigation, the man was not a resident of the community, so what was he doing before he came out of the community? The suspicion of committing the crime has further increased.

During the interrogation, when faced with this question from the police, the man responded with silence. The suspicion of committing the crime has increased significantly.

In the end, when the interrogator casually asked the tentative question of "what kind of grudge do you have with Wang Yuange, and why do you have to kill him", the man was shocked and revealed the truth.

According to the man, he was leaving his girlfriend's house and returning to his home. Because his wife was on a business trip, he suddenly returned home after changing his itinerary, but he didn't see anyone else, and called him to ask him what he was doing, he said he was playing cards, and said that he would go back immediately.

At the same time, because his girlfriend's husband also works in the public security system, his girlfriend once mentioned to him that her husband seemed to suspect that she had someone outside.

Therefore, when facing the menacing police officer, the man's first thought was: This may be a "trick" used by his girlfriend's husband, as long as he doesn't admit it, this kind of thing is not to catch a woman in bed, and no one can do anything about them.

That night, the husband of the man's girlfriend went to the police in another place.

After investigation, what the man said was true.

After a farce, Ma Hongwen proposed a new direction of investigation.

Since there were no traces of a struggle at the scene, it is more likely that the murderer was an acquaintance under the premise of assuming that Wang Yuan'e was "killed by him".

At the same time, the "murderer" did not appear in the surveillance video at the gate of the community. From the perspective of the combination of the two, if there is a "murderer", then before the crime, the "murderer" is very likely to use the identity of an acquaintance and appeared in Wang Yuange's community. This can only be done on the basis of being fully familiar with the community environment and knowing the blind spot of the community gate monitoring.

In the process of the original household visits, when the case-handling personnel learned about the situation from the residents of the community, of course, they not only asked them "did they see any suspicious people entering and leaving Wang Yuange's house on the day of the crime", and other questions, but also asked questions such as "In Wang Yuange's house, did anyone usually come to visit the door".

But this aspect has not gained much. Just from the mouths of the residents of the community

learned that before Wang Yuan'e "became famous", it seems that several men occasionally appeared in his house. As for what these men look like, the ghost remembers, and what their names are, and the ghost knows.

On this basis, Ma Hongwen began to arrange for sorting out Wang Yuange's social relations, focusing on investigating acquaintances who were close to him, and trying to identify the people who had visited Wang Yuange's house.

acquaintance, and once visited Wang Yuange's house. Only those who meet these two conditions at the same time are suspected of committing a crime. This is another of Ma Hongwen's investigative ideas.

Wang Yuan'e has no regular job, and makes a living by renting out the façade and real estate left by his parents, and he is also a small "charter company".

Therefore, the police can only understand, contact, and find people who are close to Wang Yuan'e by visiting his hometown and the school he attended based on his upbringing, including Wen Tao. After interviewing, investigating, and verifying, these people had no motive or time for committing the crime, and they were all ruled out as suspects of committing the crime.

At the same time, it was confirmed that the "men" in the mouths of the residents of the community belonged to the list of relatives and friends who were excluded from the suspicion of committing the crime.

Therefore, the clues of the investigation among the residents of the community were also interrupted. Ma Hongwen's other direction of investigation seems to be about to be declared dead.

Among the many case-handling personnel, there is a person named Duan Ming, who has a further view on the basis of Ma Hongwen's given investigation ideas.

Duan Ming believes that based on the fact that the traces of outsiders at the scene were cleaned up and the surveillance equipment was successfully avoided before and after the crime, the "murderer" should have a fairly high level of counter-reconnaissance, which fully reflects his professional ability to cover up the "murder".

There is no doubt that the average person does not possess this ability.

Therefore, it is very likely that the "murderer" is not only Wang Yuan'e's "acquaintance", but also "acquaintances" who have been invited or hired as "professionals", or as Wang Yuan'e's acquaintances, they themselves have "mature experience" in this area and can complete all this independently.

Judging from the investigation of Wang Yuange's few relatives and friends, they are all ordinary people, have no criminal records, and have sufficient alibi evidence.

If the crime is committed alone for an acquaintance, then this person should not be among the target groups that the police have investigated.

In any case, it is also possible that Wang Yuan'e's acquaintances hired "professionals", or also called "professional killer" helpers.

While other investigators continued to track down and investigate Wang Yuange's relatives and friends, Duan Ming decided to try to verify it from the idea that Wang Yuange's acquaintances had hired "professional" helpers.

As an acquaintance, he can knock on Wang Yuan'e's door in the middle of the night, and then look for an opportunity to put an excessive amount of *** in Wang Yuan'e's water cup or drink, and after he drinks and falls unconscious, he will call in the "professional" who has been following him and standing outside Wang Yuan'e's house, and he is responsible for hanging Wang Yuan'e on a rope to complete the process of faking "suicide", and is responsible for removing relevant traces at the scene.

Even, this person can enter the door and greet Wang Yuan'e openly as a "friend of a friend", and then cooperate with his employer under Wang Yuan'e's nose to disguise "murder" as "suicide".

The more "sophisticated" people such as "professional killers", the more they will "step on" near the scene before committing the crime and familiarize themselves with the environment, which is an inevitable requirement for professionalism. This person did not appear in the surveillance video in the short period of time before and after the crime, because he was already fully familiar with the community environment and knew the blind spot of the surveillance at this time.

But before that, is it possible that the "murderer" appeared in the video without fully understanding the location of the community surveillance? No one is sure.

Even if it appears, it is too difficult to screen out who is the suspect in the video of people coming and going.

Duan Ming thought it was necessary to give it a try. In his opinion, handling cases is the same as taking exams, and sometimes if you want to get good results in the exam, a clear mind and good luck are indispensable.

Duan Ming retrieved the surveillance video of Wang Yuange's community, and then nested alone in the office, and after watching it sleeplessly for a day and a night, he finally noticed a person riding a battery car and wearing a red dress

Woman. The woman was wearing a dress, but gloves and a hat. It's a bit strange to dress up like this.

What's even more strange is that this woman had only appeared twice on the third day before the crime, around 1 p.m. and around 5 p.m., and neither before nor after. In other words, it is very likely that this person is not the owner of the community, but to be sure, further household visits are needed to verify.

Although, the property management staff and residents of the community looked at the screenshot of the video of the woman held by the police, and they all said that before this, they had never seen any woman in the community dressed like this. But whether this woman is a resident of the community or not, no one can be sure. After all, the woman's face was not revealed. With a red dress and gloves and a hat, no one dares to pack a ticket.

At this time, other case-handling personnel questioned that maybe this woman was a family of relatives and friends, who came to visit the door at noon and afternoon, and then the owner who visited the door happened to be not at home when we visited and investigated.

Some people also suggested that maybe the woman in red was a resident of the community, but she had only moved here for a short time, so everyone didn't know her, and when we visited and investigated, she happened to be far away.

These hypotheses all explain the strange behavior of this eccentric woman, and the possibility of such a thing is real.

In the end, Duan Ming eliminated all doubts with a bundle of cucumbers.

The woman was riding in the front basket of the battery bike, always holding a bundle of cucumbers.
