Chapter 1434 Case Analysis Meeting
It took a full 24 hours from yesterday morning to now, and all the people didn't close their eyes.
Lu Chuan completed the on-site investigation yesterday afternoon and came back to the laboratory to do footprint identification and analysis. The footprints on the scene were quite messy. Lu Chuan was basically busy all night and finally basically sorted out the footprint identification and analysis report at eight or nine o'clock in the morning.
At the same time, the identification of the deceased has basically been completed, and the autopsy report from the forensic doctor is basically completed.
In addition to Lu Chuan, other main persons in charge were also present in the conference room, including Ren Qiang, Zhang Hui and Wang Shuai, forensic doctor Zhang Kai and Yang Sen.
Lu Chuan still looked at it for a week. Of course, although everyone was a little tired, they were in good spirits.
This is how it is to solve a case, especially when major criminal cases are the easiest to find clues at the beginning, the golden case is solved. 72 hours refers to the three days from the incident to the next.
Because the traces left on the crime scene within 72 hours are relatively clear, this clarity is likely to decrease as time goes by. Also, the mentality and mentality of the case handlers will reach their peak within these 72 hours. Once they pass, their energy may be gone. The staff was very tired after several days. Even if some clues were found, they were likely to be ignored due to various negligence or mental and physical fatigue.
At present, the investigation and handling of the case can be said to be relatively smooth. Although the clues from all aspects have not been fully benefited, Lu Chuan has already had some important directive clues, such as the confirmation of the identity of the dead person was completed immediately. From this point of view, the investigation and handling of the case has exceeded half of the progress.
These cases are different from general criminal cases, where the suspects take the deceased. It is more ritualistic to put it in a specific posture, so the reason why the other party does this is the motivation for the other party to commit the crime.
Stills of the suspect posing the deceased as Swan Lake, and the deceased is a senior student in the dance academy.
From this point of view, this is related. It is very likely that there is an intersection between the deceased and the suspect, and there is a high possibility of mutual understanding.
In addition, the early investigation of the missing person Wang Min has made some progress. At present, the Criminal Investigation Detachment has accepted the investigation by the police station below, which should be relatively some clues accumulated in the early stage.
"Zhang Kai, let me talk first, and report to you the specific situation of the autopsy, especially some discoveries and investigation results of the joints."
Generally, at the first case analysis meeting, Lu Chuan asked the forensic doctor or on-site investigation, and first reported the basic situation.
In the case analysis meeting, everyone will brainstorm based on the existing situation.
However, other factors such as this brainstorming and speculation about the direction of the case and the motive of the suspect, such as the crime, are not unreasonable, but have some basis.
Some basic situations at the crime scene, some scientific conclusions drawn by the on-site investigation, and the forensic doctor's death time and cause of death, etc., are all important basis for everyone's discussions next. Therefore, every time when the case analysis is conducted, Lu Chuan habitually asks the forensic doctor and the on-site investigation to speak first.
Zhang Kai has been to the Criminal Investigation Detachment for a while. He has been here since Shen Yan left the Criminal Investigation Detachment, so he arrived. It's almost a year now.
I am very familiar with everyone, so if there is no class, he and Lu Chuan have known each other for a long time.
"The death time was around 10:30 p.m. the day before yesterday was due to mechanical asphyxiation caused by the evil police." "Let's talk about the cause of this form found by the deceased at the crime scene."
Zhang Kai turned on the projector and put some joints of the body. List them in photos, which indicate that the suspect was burned with boiling water and then repeated. Adjusting the shape of the joints eventually formed the Swan Lake stills.
"The time for corpses to be stiff is generally peaked at 24 hours at room temperature, but the temperature of the corpses will affect the time for corpses to be stiff. The suspect changes the local stiffness time by burning the joints through boiling water, and only in this case can the shape of the corpses be changed without destroying the joints."
Zhang Kai introduced in detail the detailed reasons why the body was found in the warehouse where the crime was stills, as well as the reason for the redness on the joints of the body.
After Zhang Kai finished the report, Lu Chuan pointed to several photos on the projection and told some of the conclusions he had obtained last night.
"About the identification results of the forensic doctor, we can basically draw three conclusions. First, the suspect should be more proficient in dance and is likely to have a professional dance background."
Everyone agrees with this conclusion.
The ability to put a corpse in the shape of the stills of Swan Lake and stand in a standing state, this control of the center of gravity control of the dance posture is very high. Last night, Wang Shuai and his team immediately conducted an interpersonal investigation of the deceased after confirming the identity of the deceased.
While learning about the relevant situation while chatting with the deceased's teacher, Wang Shuai specifically asked about the difficulty of this Swan Lake shape.
In fact, generally speaking, it is quite difficult for professional dancers to dance out of the swan dance style, and it is also very difficult. This is a branch of ballet that requires long-term practice. The most important thing is that the duration of the ballet style is an important indicator to consider whether this movement is proficient.
The newest ⊥Xiao⊥Speak⊥Send⊥Six⊥9⊥Book⊥⊥⊥⊥Back⊥⊥⊥⊥!
When a person stands on one leg and remains still, it is difficult not to mention other shapes, let alone maintain the relevant shape and then keep it still, which has a very high control over the body muscles.
Therefore, Lu Chuan found out that the suspect had a professional dance background, and everyone recognized this conclusion.
"The second conclusion is that the deceased has conducted very in-depth research on the stiffness of the corpse. By pouring the joints with boiling water, the time for the corpse to be stiffened is delayed, and then the relevant dance shapes are posed through this method. Most people don't know this method at all."
After listening to this, everyone agreed with Lu Chuan's point of view, because even if they deal with corpses and cases all year round, to be honest, no one knows that there is such a detail.
If it is not forensic doctors of their own, if it is not handled, there are quite a lot of experience and they don’t know such details at all, so how did the other party know.
Of course, what kind of profession is, it must be reflected in the investigation. It is not impossible to infer that the other party is a forensic doctor.
Lu Chuan then analyzed.
