Cheng Wei snorted and said, "Do you see the blood footprints on the windowsill?"
Zhou Qianxin looked down and found that there were indeed a few blood footprints on the windowsill, and immediately responded: "I saw it, it's quite obvious."
"yes."
Cheng Wei bowed his head, pointed out the window and said: "There are several rows of sewer pipes, cable pipes and other pipes not far from the window sill of the master bedroom, the diameter of the pipes is quite thick, and there are also a few bloody palm prints and blood footprints on it.
I guess the killer used this pipe to escape the scene. ” "No" Zhou Qianxin was shocked: "This is the sixteenth floor, if you are not careful, or if you don't have the physical strength to get out of your hand, you will definitely die if you fall." ” "Killing people in such a brutal way as beheading, if he doesn't escape and is caught by us, he will really die, and he will definitely be shot."
Yuan Youchong's voice came from behind him: "And sliding down the pipeline, it seems to be risky, but in fact, the technical content is not high, and it is much easier to slide down than to climb up, as long as you are brave enough, you can do it, so you can escape."
The two turned around at the same time, Zhou Qianxin patted her chest and said, "Team Yuan, when did you come in and walk without a sound, it scared me." ” "It's not long since I arrived."
Yuan Youchong waved his hand: "Continue to talk about the case."
In the past few years, there have been many cases of thieves using outdoor facilities and equipment such as gas pipes and water pipes to burglary and rob, and the news has reported it several times, so you should all have an impression. ” "It is the rise of mobile payment in the past two years, people rarely put a lot of cash at home and on their bodies, and the pipes of newly built buildings are no longer external but hidden or semi-submersible into the walls, resulting in a great increase in the difficulty and risk of climbing the pipes, and this kind of modus operandi has gradually been abandoned by them."
"For the sake of a little possessions, someone can risk climbing the peripheral pipes, let alone the murderer trying to escape the scene."
"I can't tell."
Cheng Wei frowned: "The murderer was not surrounded immediately after the killing, he is not cornered, there is no need to take this risk."
"But there's surveillance in the hallway."
Yuan Youchong said: "He must have had a lot of blood stains on his body after he killed someone, which is too obvious under the surveillance, and it is easy for us to lock on." ” "It doesn't make sense."
Zhou Qianxin answered: "When he enters the room, he will also be photographed by the surveillance, so it is pointless to leave in this way." ” "Then, what if he didn't go through the corridor into the room" Yuan Youchong pointed out the window: "He can slip down from the sixteenth floor through the peripheral pipe, so why can't he go to the top floor, sneak to this height through the pipe, and then come in through the window sill?"
"This" Cheng Wei was dumbfounded, hurriedly leaned half of his body out of the windowsill, and after carefully observing it for a while with a flashlight, he retracted his body and said with an ugly face: "Indeed, there are a few dust footprints on the upstairs section of the pipe, and the murderer did enter the room using the method that Team Yuan said." ” "Moreover, there is a small section of volley windowsill outside the window, about 30 centimeters wide, enough to settle and rest, and the volley window sill is next to the peripheral pipe, if the murderer is tired and his hands and feet are weak, he can take a break on the volley windowsill, which greatly reduces the risk and difficulty of climbing."
Yuan Youchong snorted and said, "Then I'll ask Lao Yu to go downstairs and search to see if I can find any clues."
Lao Cheng, give him a trace inspector. ” "Okay."
So, he picked up the walkie-talkie and told Yu Chen about it.
Zhou Qianxin's face was black: "No, Team Yuan, you are too lazy to run for just a few steps, and you have to use a walkie-talkie" He shrugged his shoulders, just wanted to explain a few sentences, but suddenly remembered something, simply didn't explain, and asked directly: "By the way, Xiao Zhou, I forgot to ask, this suite is separated from your house by a few households, you can be regarded as neighbors, do you know her?"
"I don't have any impression, maybe I've met a few times."
Zhou Qianxin smiled bitterly and shook her head: "Living in this kind of unit building, not to mention that there is a corner in the middle of a few households, even if it is door to door, I am afraid that you may not be able to know each other, at most you have taken the elevator." ” "In addition, I often don't go home for your cases, I live in the detachment for a week, and I don't have many opportunities to meet my neighbors."
"Yes."
Yuan Youchong obviously didn't have much expectation in this regard, so he waved his hand and said: "It's okay, it's not difficult to confirm the identity of the victim, look for something like an ID card."
"Her name is Bi He, after all, Bi, the lotus of the lotus, is twenty-five years old this year."
Cheng Wei said: "Her wallet is on the bed, and in addition to her ID card, there are more than 600 yuan in cash and a few bank cards. ” "In addition, she is married, married the year before last, has no children for the time being, her husband's name is Lu Yuping, and the marriage certificate, real estate certificate, household registration book, etc. are on the third floor of the bedside table, and there are necklaces, bracelets, old mobile phones, old tablets and other objects in the cabinet."
"Married" Yuan Youchong's eyes narrowed slightly: "What about others, who are not at home in the middle of the night, on a business trip or working overtime, I asked people to quickly contact him and ask him to come over."
You will complete the site investigation work as soon as possible. ” "No problem."
Half an hour later, the on-site survey was completed.
Cheng Wei reported: "There are no traces of violent damage to the doors and windows at the scene, but considering that the murderer is likely to have come in from the windowsill, combined with the windows in the living room and another bedroom, although the windows are closed, they are not locked, and they are opened right as soon as they are moved. ” "Several fingerprints and bloody fingerprints were found on the window, but there were no lines on them, so it can be seen that the murderer wore leather gloves or rubber gloves throughout the whole process of entering and leaving the bedroom and committing the murder, and his sense of anti-investigation was strong.
In addition, blood fingerprints were also found on the lock of the living room door, which shows that the living room door was opened by the murderer. ” "The victim's property has not been lost, and there are no traces of rummaging at the scene, which can rule out the possibility of murder for money, burglary, or robbery and homicide.
There were signs of a struggle at the scene, but there were not many, so it is assumed that the victim was quickly controlled by the murderer, in other words, the victim had little power to resist in front of the murderer. ” Judging from the length of the shoes and the walking stride, the height of the perpetrator is about 1.85 to 1.9 meters, and the body should be relatively strong and agile.
Well, it's about the same as Team Yu. ” "That's pretty much it."
After he finished reporting, Zhou Qianxin also said: "No suspicious murder weapon was found at the scene, the kitchen knives and fruit knives in the kitchen were still placed in the distance, and they were not moved, the murder weapon should have been brought by the murderer, and he was taken away when he left." ” "In addition, no nylon rope or other restraints were found at the scene, and it is estimated that they were also taken away by the murderer, except for the lower half of the victim's body, there were only spilled internal organs on the bed, and a towel with a little blood and saliva."
