At seven o'clock in the evening, Yu Chen and others returned to the detachment and held a seminar on the case.
The detachment, especially the serious case brigade, is like this, when there is no case, it is very idle, and when there is a case, it rotates 24 hours a day.
Therefore, for the criminal police, strictly speaking, there is no definition of off-duty at all, because no one dares to guarantee that there will be no cases falling on their heads after work, on the contrary, the night is still a time for high incidence of crime.
Therefore, it is more appropriate to call it "on call at home" when you leave work.
In the conference room, Yu Chen looked around and saw that all the members of the serious case group, Fan Yuhong and two technical policemen, Cheng Wei, Lao Hu Laoqiao and Zhou Qianxin were all present, so he coughed lightly and said: "Everyone suffers a little tonight, work overtime, and when the case is solved, I will invite everyone to dinner."
A simple sentence can be regarded as an opening statement, and then, he looked at the probationary criminal police officer who had just been assigned to the serious case team and was responsible for visiting the investigation, and asked, "I heard that the source of the corpse has been determined."
"That's right."
The trainee participated in this kind of serious case meeting chaired by the detachment leader for the first time, and was very excited, and immediately said: "The victim's name is Ban Yingying, female, 26 years old this year, married, with a son, and her husband's name is Cao Haolin. ” "The victim currently works in a bar and is a bartender by profession.
We went to the workplace to check, called up the surveillance, and found that she had come home from work at 11 o'clock last night.
The husband claimed that he did not see his wife return. ” Zhou Qianxin nodded: "The time is right."
According to the results of the autopsy, the victim died between 1 and 2 a.m. today. ” Yu Chen snorted and gestured to the trainee to continue.
"After our visit and investigation, we found that Ban Yingying and her husband Cao Haolin have a deep grudge.
How to say it, Cao Haolin has always disagreed with Ban Yingying working in a bar, thinking that kind of place is mixed, and it is not good to say.
Ban Yingying believes that her salary is quite high and she does not want to resign. ” Just because of this, the two quarreled many times, but according to the neighbors, they were more restrained and did not rise to the level of domestic violence.
We believe that this Cao Haolin has a certain suspicion of committing the crime, but now it seems that it can be ruled out. ” "Oh" Yuan Youchong spoke: "What do you say?"
"Last night, at about eight o'clock, after Cao Haolin coaxed his five-year-old son to sleep, he has been playing games in the living room at home until three o'clock, playing a stand-alone game, and seeing that his wife has not come back, he went to sleep, and he has not gone out during the period."
Yu Chen's eyebrows tightened: "How can I prove that his son is asleep if he hasn't gone out of the stand-alone game he plays, and there are no netizens who are online at the same time, I'm afraid" "Surveillance can prove it."
The trainee hurriedly said: "Cao Haolin has a cat at home, he often likes to see what the cat is doing at work time, so he installed a smart camera in the living room at home, and the picture is still quite high-definition, it can be seen that he has never left the computer desk except for going to the toilet." ” Gu Yandong, the leader of the "camera" group, couldn't help but sneer: "Who would install surveillance for a cat, I think it's just an excuse to see the cat, and it's true to supervise whether his wife is stealing."
Zhou Qianxin raised her eyelids and said lightly: "You don't know anything about cat slaves.
Suck is addictive, I can attest.
Moreover, I also have cameras at home, and there are more than one, just so that I can see my rice balls and zongzi in my free time. ” For this straight man of steel, Zhou Qianxin has always had no good feelings.
Gu Yandong was choked by her, and immediately remained silent and stopped talking.
Yu Chen immediately came out to talk around: "Okay, this question is not important.
Now that Cao Haolin has a perfect alibi" Speaking of this, he suddenly paused and turned his head to look at Fan Yuhong: "Old Fan, with your experience, is there any possibility of cost for the monitoring screen of this kind of smart camera?"
"Yes, but you can only record a certain piece of footage in a fixed or loop, and it's easy to see through."
Fan Yuhong said: "The smart camera, in fact, is essentially a camera that can be connected to the Internet, although it can hack in, but at best it can only secretly shoot some videos, or simply fix and loop the picture." ” After thinking for a while, Yu Chen asked again: "Is it possible to record a video in advance and then change the time?"
Fan Yuhong hesitated for a while, discussed with the two technical officers on the side, nodded and said, "There is a certain possibility, but it should be able to be investigated." ” "It should be" Yu Chen frowned, and then said to the trainee: "The video copy is back, and it will be sent to the technical team later."
Oh yes, go back and get the camera back, and give it to Lao Fan. ” "Understood."
The trainee said: "In addition, we also intercepted the surveillance video along Ban Yingying's way home from work, and found that Ban Yingying entered a 500-meter-long unmonitored alleyway after leaving the bar and never came out. ” "After the comparison of past surveillance videos, this roadway is the only way for Ban Yingying."
Yuan Youchong touched his chin and said, "In other words, her place of work is not far from her home."
Yes, less than two kilometers, she usually walks home, occasionally stopping at the door of her community for a barbecue or inviting friends to sing.
We investigated, Ban Yingying did not ask anyone that day, and when she walked into this lane, she should have gone home directly. ” "The investigation is quite detailed."
Yu Chen said: "Then, the victim should have been abducted by gangsters in this unmonitored alleyway."
Lao Cheng, you report your work, and then immediately take someone to the scene to investigate, and report it immediately if you find clues. ” "Understood."
Cheng Wei stood up and said: "The scene of the dumping of the body was almost washed away by the rain, and the only row of suspicious footprints found was newly left. ” "We also inspected the sack containing the body parts, and extracted several fingerprints, all of which were left by the informant, who had stains on his hands, and was curious to open the sack to check the fingerprints.
In addition, there are three bloody fingerprints, but there are no lines on the fingerprints, and it is speculated that the murderer was wearing rubber gloves when committing the crime and dumping the body. ” "Basically, that's all the clues we've gathered so far."
Yu Chen pondered for a while, waved his hand and said, "Okay, you can take someone down to work first." ” Seeing him leave with Lao Hu Lao Qiao, Yu Chen looked at Zhou Qianxin again: "Did you find anything in the forensic department?"
"Let's not talk about the time of death, the cause of death and the physical characteristics of the victim, let's talk about some of the data on the murder weapon that has been identified."
Zhou Qianxin shook her head and said: "The murder weapon is a chopping weapon with a blade length of about 22 to 24 centimeters and a certain thickness and weight. ” "By the way, one more point, the murderer washed the body with clean water."
