Gu Yandong shook his head: "No."
"No" Yu Chen was stunned for a moment, and asked strangely: "Xiao Zhou, Lao Cheng, and even Lao Yuan's side didn't find out that there was no gain, I can understand, how can there be no clues on your side, anyway, the suspect has to enter the unit building, otherwise he will go to the rooftop."
"Theoretically, that's the case" Gu Yandong's face was also very entangled: "But it's true that there is no clue, and I can't figure out how he got up" "Don't worry."
Yuan Youchong spoke: "Let's talk about it carefully, what's going on." ” "Hmm."
Gu Yandong bowed his head and said: "That's the case, before the monitoring was called, we also called up the information of the owners of the 11 buildings and 2 units, and learned about the situation like the security guard in charge of the unit." ” "How to say it, in recent years, the speculation group is too crazy, coupled with the rising housing prices, we Xin'an said that every inch of land is not an exaggeration, which has led to many newly built communities in the first house type are strange to death, it seems that when it was built, it was thought of using it to speculate rather than to live."
"For example, next to the Yaping Xinyuan Community, less than 500 meters away, a few years ago a new community was built, called Tianjiao Garden Community, you guess how strange the house type is 18 square meters dare to engage in a one-bedroom and a living room, the three-bedroom is not 50 square meters, and a large chase room, I can't get on 60 square meters, just ask if you are afraid" "Generally speaking, there are many things to consider when buying a house for self-occupation, including location, house type, decoration, property, etc., like this kind of strange house type, those rich people will not live at all even if they buy it, and they will either speculate or rent it out after buying."
"However, the unit price of the new community is still high, the property fee is also expensive, and it is often not cheap to rent out, so the occupancy rate of the new community is often relatively low, and the occupancy rate of Tianjiao Garden is not even 30%, and the vast majority of people either choose urban villages or old communities."
"Especially in a community like Yaping Xinyuan, which is half-new but not old, the house type is not bad, and there is an elevator, and the rent is not high, it is the most popular, and the occupancy rate is extremely high."
Yu Chen plucked out his ears and complained: "Having said so much, sparing such a big circle, you just want to say that there are too many residents in the unit where the crime occurred and it is difficult to investigate."
"Uh" Gu Yandong was a little embarrassed, smiled wryly, and said: "Yes, and the 11 buildings and 2 units are still the largest units in the community, and there are many residents." ” "You think, that building has 20 floors, and then there is the rooftop, the shops on the first floor, the 2nd to 20th floors are residential, 10 two-bedroom apartments on each floor, almost all of them are full, at least 170 households, plus guests, water and takeaways, how big is the flow of people every day."
"Hmm."
Zhou Qianxin answered: "I feel this very deeply, many times, I have to squeeze the elevator downstairs for a long time in the morning." ” Seeing Zhou Qianxin's rare echo of herself, Gu Yandong was surprised for a moment, and then quickly nodded: "That's right.
What's more, we also have to take into account the possibility that the murderer went to the rooftop to ambush a few days in advance in order to avoid being photographed by the surveillance. ” "It's not unreasonable."
Yu Chen thought for a moment and looked at Cheng Wei: "Has the rooftop been investigated?"
"Checked."
Cheng Wei immediately said: "There is a lot of dust accumulation on the rooftop, leaving a lot of obvious shoe prints, including the suspect."
However, the number of shoe prints is not too large, and there are no other special traces, so he should not stay for a long time, at least not more than half a day. ” Yuan Youchong snorted, and then said to Gu Yandong: "Okay Lao Gu, we also understand your difficulties, no need to explain anymore, just say the result." ” "Okay."
He flipped through his notebook and said: "From the morning of the 26th to the death of the victim in the early morning of the 27th, the surveillance of the three gates captured a total of 17 people who entered the unit building, and a total of 17 people who were more than 1.8 meters tall were visually measured. ” "Nine of them can be identified as residents of this unit and entered their rooms, although a few have been out a few times, but soon returned to their homes, which can be ruled out."
"The remaining eight people are food delivery, gas delivery or water delivery, and they leave after delivering the goods to the target households, which can also be ruled out as suspicion."
"If the scope of the investigation is relaxed to three days, the results are similar, the nine households are still fine, and the suspicion of some other service personnel can also be ruled out."
"In other words, within three days, those who entered the unit building where the crime occurred, were photographed by surveillance, and were visually measured to be more than 1.8 meters tall, were not suspected of committing a crime or had the conditions to commit a crime."
"This" Yu Chen listened to his words, and was also confused: "Strange, how did the murderer go up Lao Yuan, what do you think?"
"I can't say."
Yuan Youchong also frowned: "In this way, let the colleagues of the graphic investigation carefully monitor it again to see if any details have been missed." ” "That's all there is to it."
Yu Chen nodded helplessly, and then, he heaved again, and looked at Zhou Qianxin with the attitude of a dead horse as a live horse doctor: "Xiao Zhou, do you have any opinions?"
"I have an idea, but I don't know if it's reliable or not."
She frowned and said: "Those service personnel, it is okay to photograph them entering and leaving the building, and eliminate their suspicions, but if the suspicions of the residents are ruled out, it is a bit arbitrary." ” "Do you think, the murderer's sense of anti-investigation is particularly strong, so will he deliberately mislead us If the murderer is a resident who lives on the upper floor of the victim, then, is it possible, he deliberately found an opportunity to step on the rooftop and walk around, but he did not slip down from the rooftop at all, but from his own home" "No, it won't."
Cheng Wei interrupted her and said: "Climbing marks and shoe prints were found on the cement guardrail on the rooftop and on the volley eaves outside the guardrail, and the shoe prints of the peripheral pipes also appeared at the top, which is enough to prove that the murderer climbed down from the rooftop, and not to set up smoke bombs." ” "That's right."
Zhou Qianxin blinked and said, "Then I can't think of it." ” "Well, forget it."
Yu Chen was a little disappointed and said, "Then let the detective go through the surveillance video again."
Well, Lao Yuan, it's your turn, what have you found here?"
"Not either."
Yuan Youchong shook his head: "You have investigated the vicinity of the unit building where the crime occurred, and it should be very clear that when the murderer climbed to the bottom of the building, the blood marks on the soles of his shoes had already been scratched, and the blood footprints around the bottom of the building could barely be found with luminol reagent, but farther away, even luminol was gone." ” "The same is true around the flower garden, the murderer rubbed the soles of his shoes on the grass, and after walking a distance, he couldn't detect anything, and he couldn't determine the whereabouts of the murderer."
