As Du Dayong spoke, everyone below was recording, except for a few criminal policemen from Fucheng County.
Everyone knew that Du Dayong's analysis was carefully considered, and every newcomer knew that the veteran players and the leaders of their own squadrons all had thick notebooks, so they all followed suit, and everyone prepared thick notebooks.
The notebook begins to record.
"In my personal opinion, let's not rush to determine whether this case is intentional homicide due to embezzlement of property, retaliatory homicide, or other types of intentional homicide. At present, we are not able to determine the direction immediately. We are criminal police officers.
To understand the logic of crime, there must be external and internal causes for the formation of such a logic. Let’s start with the internal causes. We must first trace back all the social relationships of Cui Erquan, Luo Honggui, Cui Sheng, and Wu Gengxiang, and sort out all the social relationships of each person.
Once, if no consistent logic is found in the internal factors, we will also sort out whether the internal factors will lead to the formation of external factors. I believe that there will be the formation of external factors. Then these formation points can become the surface for us to detect, and it is also our
The key investigation directions that future investigation work will focus on.”
"He Wuwei, you will be responsible for checking the total income of this family tomorrow. From the raw materials they collected to their selling prices, after deducting all their costs, see how much spare money they have in addition to the bankbook figures. Such spare money is also
It determines whether the criminal suspect has enough motivation to kill four people in a row."
"But first of all, let me make it clear that this case can completely rule out the possibility of random crimes. Don't spend any energy and time here. Not to mention that the scene can be arranged. The suspect is a veteran criminal. Don't have such thoughts. I have already
I heard some new team members mention this. Please go back and think about the logic of the crime. If you don't understand it, you can raise it now and I will answer it for you."
Sure enough, a female police officer from the intelligence squadron raised her hand and said.
"Captain Du, my name is Lu Qianqian. What you just said is what I think. I mentioned it to our Captain Tang, but I think this possibility is still possible."
Du Dayong looked at this good-looking policewoman and nodded.
"Lu Qianqian, have you seen the photos of the crime scene?"
Lu Qianqian nodded after hearing Du Dayong's words.
"Was the murder weapon taken away or taken on site?"ωωw..net
"According to the preliminary and detailed forensic examination, it was taken from outside."
Lu Qianqian answered immediately.
"Did the suspect prepare the veterinary anesthetics in advance?"
"Yes!"
"Are there any signs of violent entry into the victim's residence?"
"No!"
"Then it can be considered that the criminal suspect at least knew that Cui Erquan and his wife were selling pickled vegetables, and at worst used this excuse to enter?"
Lu Qianqian blushed immediately!
Nod quickly.
"Were the two crime scenes entered peacefully? So after killing Cui Erquan and his wife, how long did it take to go to Cui Sheng's residence?"
"Judging from the forensic report, it lasted about one and a half to two hours!"
"How far is the distance between the two places?"
"About three kilometers!"
Lu Qianqian was sweating a little now!
"Three kilometers, how long would it take to get there by bike?"
"It takes no more than fifteen minutes on a bicycle, and no more than twenty minutes if it's at night. If it's a battery bike, it's faster! It takes about half an hour to walk, and fifteen to twenty minutes to run, which is relatively fast.
That kind!"
Du Dayong listened and nodded. This Lu Qianqian answered quite comprehensively.
"If someone kills someone randomly, how many tasks do you think the suspect needs to prepare for?"
"You need to have the most basic checkpoints, and then you have to prepare a series of tasks, transportation, murder weapons, and finally take away the children. You know, there is a return behavior here. After Cui Erquan and his wife were killed, the suspect
Instead of killing the child, he went to the residence of Cui Sheng and his wife and continued to kill Cui Sheng and his wife. This situation should be difficult to accomplish with a child, but it is not ruled out that the child was stunned, and then a person took it from Cui Erquan's place.
It is a crime of entering a house with a key and carrying a child on his back. But the possibility of this is very low. Here I admit that I have thought that this should be done by two criminal suspects, but all the on-site materials do not support my view.
, if there are two people, then Cui Erquan will definitely be on guard at that point in time, and the commotion at home should not be small, because judging from the victim's anesthetized state, it was not completed by two people, but by one person. If more
If there is a suspect, then Cui Erquan will not have no traces of struggle. What is more worth considering is that at that time, Luo Honggui should have been awakened. Similarly, we did not find any traces of struggle on Luo Honggui.
The most important point is that the four victims had the same anesthesia needle holes and the same wound incisions."
"This is what bothers me very much, so I will see the scene in person tomorrow and look for any omissions on the part of the suspect at the crime scene. But does my explanation above prove that this is not a case of random homicide?
