Lei Zheng said: "In that case, the problem may be on the murderer's side, Officer Wang, you investigated the surrounding videos, did you find any suspicious characters?" ”

Wang Mingqi said: "I found out, the murderer left at five o'clock in the morning, he wore a hat and lowered his head, the security guard said that he took a nap at the time, and did not see the murderer's appearance, we followed and found that the murderer left on an electric motorcycle, and he couldn't find it after crossing an intersection, which was basically the same as the previous five times." ”

Lei Zheng said: "The murderer left at five o'clock, and the deceased's husband came back at six o'clock?" That's too much of a coincidence, isn't it? ”

Wang Mingqi said: "We are also a little suspicious, but we investigated and found that the deceased's husband called the deceased at nine o'clock last night, saying that he would come back early in the evening and ask the deceased not to lock the door, and the murderer may have learned the information from it and left the scene in time." ”

Lei Zheng asked, "Did the deceased's husband work a long night shift last night?" ”

Wang Mingqi seemed to be annoyed by the question, and he said in a somewhat unhappy tone: "The deceased's husband went on a business trip to another place, and because things went well, he came back early. ”

Lei Zheng asked, "When was he expected to come back?" ”

Huang Lewei came over and said, "Let me come, Captain Wang, you go to the door." ”

Wang Mingqi said: "Go, go, you go by yourself, the husband of the deceased was expected to come back for almost a week." ”

Lei Zheng said: "It seems that this is probably the reason why the murderer acted in advance, the murderer knows so much about the situation of the deceased's family, and can easily enter the deceased's home, Officer Huang, have you launched an investigation into this?" ”

Huang Lewei smiled: "Don't be so polite, call me Ah Wei, we have investigated, the door lock of the deceased's house has no traces of damage, but the lock of their house is relatively simple, and the possibility of being unlocked by technology is not ruled out, of course, it is possible to follow the entry or have a key, and it is possible to deceive the door by express delivery, etc., the husband of the deceased cannot confirm whether the key at home has been copied, he said that the deceased is more likely to be gullible and is more likely to be deceived into opening the door." ”

Lei Zheng said: "Assuming that the deceased's husband called back at nine o'clock before the deceased had not been kidnapped, then the murderer should have rushed to commit the crime after getting the news, then the time is at least after nine o'clock, and it may not be so easy to deceive a woman who is alone at home, right?" ”

Wang Mingqi said: "It's hard to say, some people are not alert. ”

Lei Zheng said: "Well, based on these five cases, I found that the murderer knew the deceased's family situation very well, and I suspect that he had entered the deceased's house, otherwise it would be impossible to even know the direction of the deceased's bed, and one of the reasons why the murderer chose the target is likely to be the direction of the bed." ”

Xie Huiqing frowned, then let go again, she said: "Yes, this is probably a feature that we have all overlooked, based on the dial theory, if the position of the bed is not right, the murderer will not be able to pose in the correct direction, which should be very important to the murderer." ”

Lei Zheng said: "Yes, so he knows the deceased's family well, and he also knows the roads around the crime site well, and the time when he stepped on the spot may be much earlier than the time of the crime, so you can't find any trace of him when you check the recent footage." ”

Huang Lewei nodded and said: "It seems that this is indeed the case, but it is a pity that neither the community video, nor the Skynet video nor the video of the transportation department have been kept for more than two months, most of them are within a month or even only ten days, and we have no way to check further." ”

Lei Zheng said: "Then check from other aspects, the murderer has left us a lot of clues, but unfortunately we can't interpret it for the time being, based on the current situation, I think the murderer should have entered the deceased's home in a peaceful way, he has a certain funeral experience, he also knows how to pick locks, maybe he has been a locksmith registered in the Public Security Bureau, his current profession is relatively free, and it is easier to gain trust...... You can look for and approach targets everywhere ......"

Huang Lewei frowned and said, "Is it a courier or a salesman?" ”

Lei Zheng shook his head and said: "No, it's not a holiday, the courier won't be busy until after eight o'clock in the evening, as for the salesman, it is estimated that normal women will not let him in at such a late hour." ”

Huang Lewei said: "It's a pity that there is no monitoring in the corridor, otherwise we can know how the murderer entered the door." ”

Lei Zheng thought about it, and suddenly walked out, Xie Huiqing, Huang Lewei and Wang Mingqi followed, only to see Lei Zheng looking for something in the corridor, Wang Mingqi said: "They all said that there is no monitoring, what are you looking for?" ”

Lei Zheng said: "I found the distribution box." ”

Lei Zheng came to the end of the aisle, where the lights were very dim, so Huang Lewei took out a flashlight and shone it on the lid of the distribution box.

Lei Zheng said: "On the ground, look, this place is very clean, and the murderer should have left traces here, so he cleaned it up." ”

Wang Mingqi scratched his head in annoyance, he only paid attention to the inside of the deceased's house, but he didn't notice that the murderer had done a ghost outside the door.

The distribution box was carefully opened by Lei Zheng and Huang Lewei, only to see that everything inside was normal, Huang Lewei brushed it with his fingerprint, and found nothing.

Lei Zheng said: "Maybe the murderer restored everything to its original state when he left, we can imagine that when he was surfing the Internet or watching TV in the middle of the night, suddenly the power went out at home, and then someone knocked on the door and claimed to be a community electrician, saying that the whole building was out of power, and it was suspected that there was a problem with the circuit in your house, and you couldn't open the door?" ”

Huang Lewei and Wang Mingqi both thought about it, and Wang Mingqi said: "I will go to the balcony first to see if there is electricity in the neighbor's house." ”

Xie Huiqing said: "That's because you are a police officer, and you are more vigilant, but ordinary people are not so vigilant, and many similar cases are violated because women casually open the door to outsiders at night." ”

Wang Mingqi nodded helplessly and said, "Now I probably know how the murderer entered the deceased's house, so what?" We still don't know anything about the murderer. ”

Lei Zheng said: "Maybe the murderer is an electrician?" Ah Wei, go and check, whether the five crime scenes belong to the same area, and whether the same group of people are responsible for circuit maintenance? ”

Xie Huiqing said: "In the same way, Xiao Huang, you can check the departments of cable telephone, cable TV, tap water, and pipeline gas to see which company's maintenance staff is responsible for these places at the same time." ”

Lei Zheng said: "The deceased once let the murderer into the house, which means that it is likely to leave a record of maintenance or new installation, and compare and investigate to see if there is a corresponding." ”

Wang Mingqi said: "It shouldn't be a wired phone, because there are no wired phones at the five sites, only this one and that transgender person's home uses piped gas, which should also be ruled out, in addition, I think we should also check the delivery records of the big shopping malls, they are generally the same people sent to the whole city, according to my observation, these five sites have some relatively new major appliances, and they must be delivered to the door." ”
