"Otherwise, everyone is busy, and we have nothing to do, so let's say no, let's do some work."
"You're right, but I didn't say we didn't work.
"Forensic medicine is a very professional discipline, not to mention you, even if it's me, I only know a little bit and dabble in it, but I can't help if I want to help, and I can't help it.
"In that case, why do we have to stay here and help Lao Cheng.
Although the professionalism of trace examination is relatively strong, it is a compulsory subject in the police academy, and I have studied it, and my grades are not bad, which can help a lot. ” "Yes."
Yu Chen thought for a while, and said: "In some ways, trace inspection and reconnaissance skills in the army are actually related to and even the same, and reconnaissance is also a skill that officers and senior soldiers must master, and I am also good at it." ” "That's not it."
Yuan Youchong raised his eyebrows: "So what are we doing here?"
"Yes, yes, you're right."
By six o'clock in the morning, the sky was already bright, and they could be regarded as having basically completed the "preliminary survey" work.
Of course, after dawn, there is a certain amount of interference with the trace inspection.
For trace inspection, good lighting has many advantages, but it is mainly conducive to observing the macro environment of the site and checking the damage of the entire site, while some microscopic clues are easier to find in a dark environment.
For example, many fluorescence reaction experiments, as well as violet lamp observation methods to observe subtle clues such as fingerprints and ground hair, need to create a dark environment as much as possible to shield from ambient light interference.
Therefore, for a night, they did not think about connecting the cut cables to restore the power supply in the villa, they were all working with flashlights, and it was not until dawn that they sent a criminal police officer who was more proficient in electrician skills to connect the cables.
In the end, the conclusion was the same as before: the murderer had carefully cleaned the scene, and the traces left behind were basically not worth investigative identification, but it was certain that he had been in and out of various bedrooms more than once.
The three rooms where the fire broke out were also investigated, but to extinguish the fire, how could it not damage the scene, even if the fire fighters had been as careful as possible, it still did not help, at least the fire scene was like this.
Counting the objects in the three rooms, restoring their furnishings before the fire, and finding out the specific location of the fire point and the trend and direction of the spread of the fire is the limit.
As for Zhou Qianxin, after completing the examination of the corpse table, with the help of the criminal police, she put eight corpses into a body bag and carried them onto the corpse transport vehicle of the forensic department, and pulled them back to the criminal investigation detachment.
There were eight corpses, and the inspection task was quite heavy, she didn't delay for a moment, and even the inspection results reported to Yu Chen and Yuan Youchong were very concise, with only one sentence: there was no discrepancy from the conclusion reached before, and the time of death of the eight victims was quite close.
Of course, on-site investigation cannot only be traced and autopsied, but also a lot of peripheral work, such as visiting neighborhoods, obtaining surveillance in the community, and so on.
Because it was late at night, the task of the visit was not large, and it was handed over to Xiao Wei and other three policemen, who did not get many valuable clues, and only confirmed the news that Xiao Wei got at the beginning: the victim's family did have two drivers and three nannies.
And this, the technical team has been determined before the two of them, and even the name, age and identity have been known, and it has also been found that Lu Shanshan lives in the villa where the crime occurred, Bai Guoxin occasionally stays overnight, and the other three basically go back to their homes after dinner.
In addition, Zhao Yanghong also left a fairly detailed transcript, which is very detailed, and it is speculated that he should not be lying.
After all, lies, especially those that come up on the spur of the moment, often have serious or no details at all, and if they are made up, they will be full of loopholes.
Of course, it would be too arbitrary to rule him out of suspicion just once, and further investigation will be needed to determine whether he was lying.
After counting the clues obtained so far, Yu Chen frowned and said: "I investigated all night, but the clues obtained were pitiful.
I expected that this case would be difficult to handle, but I didn't expect it to be so difficult.
Old Yuan, do you have any ideas?"
"Don't worry."
Yuan Youchong said: "The colleagues who went to monitor have not yet replied, and they may have made important discoveries." ” "Come on."
Yu Chen didn't have hope at all: "The cables in the villa have been cut, what can the monitoring find?"
"Heh," Yuan Youchong pouted: "Old Yu, are you busy and dizzy, are they going to adjust the monitoring in the villa or do you think that the monitoring installed in the villa, such a private thing, can be networked with the security monitoring of the community property" "Uh" Yu Chen was stunned and shook his head.
"As a mid-to-high-end villa park, this community still attaches great importance to security, and the monitoring coverage rate is quite high, maybe we can take pictures of some suspicious people, and this is what we need, whether we are mentally retarded."
"Yes, yes, yes."
Yu Chen didn't bother to argue, only a little strange wondered: "However, they only need to focus on investigating the monitoring around this dormitory, it stands to reason that the workload is not too big, why haven't they replied until now?"
Yuan Youchong's neck was a little stiff during the activity, and at the same time said: "Yes, there are a lot of people we sent to monitor and monitor, and the workload assigned to each person is not large, so it stands to reason that there should be a result soon, but they have not replied for a long time, why?"
"You guy" Yu Chen knew that he was taking the test himself, so he had to smile bitterly, and after thinking seriously for a while, he said with some uncertainty: "There is only one explanation, they have a suspicion, but they can't be sure, so they watch the surveillance video repeatedly." ” "That's right."
Yuan Youchong stopped his movements and said, "So, the longer they haven't recovered, the more likely they are to find something, just wait, they should surprise us." ” As soon as the voice fell, Yu Chen's walkie-talkie rang: "Call the team, call the team" "Received" He heard that this was the voice of a detective sent out, so after glancing at Yuan Youchong, he immediately asked with some excitement: "Did you find out" the torture and murder :
