Chapter 570 Details Discovered
Although the body is ready-made, Lu Chuan has no way to conduct a direct inspection for the time being because the body is in a frozen state and has to wait until it softens.
Before this, Lu Chuan conducted a general inspection of the surface of the corpse.
The forensic capabilities of the Tianzhou City Criminal Investigation Detachment are quite good.
Forensic doctor Sun Jian and forensic doctor Wang Changjiang from the Haizhou City Criminal Investigation Detachment are also old acquaintances and have similar abilities.
It can be ranked above the middle reaches in the whole province.
Sun Jian's ability is slightly higher than Wang Changjiang.
So, Lu Chuan didn't have much doubt about Sun Jian's autopsy report. He just had some details that needed to be confirmed again.
On the one hand, I am worried that Sun Jian has omitted something, and on the other hand, I want to compare it with the QZ City 116 case.
Although three years have passed since the 116 case, the tracking and investigation of the case in QZ City has not stopped during these three years.
The families of the five student victims would not let this case go unanswered.
Lu Chuan wanted to determine some information by comparing some details of the two cases.
The superficial examination of the body was quickly completed, and the autopsy report made by Sun Jian was very detailed.
While waiting for the body to soften, Lu Chuan had been communicating with Sun Jian.
"Lower body friction injury?"
"I didn't pay special attention to this at the time."
Sun Jian's answer was also what Lu Chuan expected.
The female victim showed obvious signs of being violated. Since no relevant body fluids were extracted, this clue was not particularly important, or could be said to be a directional clue.
Lu Chuan asked whether there were any friction injuries on the deceased's lower body. The most important purpose was to compare it with some findings of the 116 case in QZ City.
Why has the 116 case not been solved in the past three years?
One of the most important reasons is that the venue is very clean!
The provincial department’s trace inspection team went out and found no valuable clues at the scene.
Such as hair, dander or footprints and fingerprints.
The suspect was on high alert at the time.
According to the description in the file, the other party climbed over the school wall.
On this side of the wall is the girls' dormitory.
The murderer climbed up from the security window to the third floor with his bare hands along the second floor.
There is no anti-theft window on the third floor, and the other party entered the dormitory through the window to commit the crime.
The traces of the entire crime are very clear, but the camera next to the school wall at that time was malfunctioning and damaged.
The murderer wore gloves throughout the crime.
The footprints were wiped away with a mop in the dormitory before the other party left.
More importantly, all investigators found only the body hair of six students at the scene, but no trace of the murderer.
This is the reason why the case has not been solved so far.
After a while, the body softened completely, and Lu Chuan focused on checking the traces on the lower body.
“There are friction wounds around and on the upper part.”
Lu Chuan's guess was confirmed. The female victim did have friction injuries around her lower body.
"This..."
"Under normal circumstances, the murderer will only cause such frictional injuries after the body hair is shaved off."
This is why , Tianzhou City Criminal Investigation Detachment did not find the reason for the murderer’s body hair.
Because the other party scratched it off.
After confirming this, Lu Chuan left the autopsy room and went to the special meeting room of the serious crime team.
Song Mingguang and Wang Song have begun to act separately, only Li Donglin is still there.
"Li Chu, I want to go to Qinzhou." Qinzhou?
“Want to go to the scene of the 116 case?”
Lu Chuan nodded: "There are some speculations, but we need to go to the scene to verify."
"And, of course, the survivors...can we meet them?"
Li Donglin had originally arranged for Lu Chuan I went to Qinzhou, but I didn’t expect it to be so soon.
While Lu Chuan set out to investigate Case 116 in Qinzhou, other groups also made some progress.
The first thing that came back was the bank card information investigated by Song Mingguang.
As expected by Li Donglin, the victim had more than three bank cards in his name.
“There are 5 bank card information under the victim’s name, three of which we found at the victim’s home.”
“The three bank cards we found belong to the three victims respectively. Among them are the salary cards of adult men and women, and one bank card is a mortgage card. "The other two bank cards contain fixed amounts of 30,000 yuan and 40,000 yuan respectively." br>
“On the day and the next day, someone withdrew the money in the bank card from the automatic teller machine.”
The information Song Mingguang brought back was very important.
Judging from the current situation, the bank card must have been taken away by the murderer.
As for the other party's method of withdrawing money, Li Donglin had already thought of it. The murderer was not the first time to kill someone, and he was very careful during the crime. It was impossible to go to the bank, so he could only withdraw money through an ATM machine.
As long as you withdraw money through an automatic teller machine, video surveillance evidence will definitely be left behind.
“Where is the monitoring?”
"It's already being retrieved. I'll report to you as soon as I get it!"
Li Donglin hung up the phone before Song Mingguang could take a breath.
Wang Song also called.
"Director Li, we found some clues in the surveillance of a supermarket."
Facts have proved that the crime team is the crime team, and its ability to handle cases is indeed awesome.
Wang Song found an important clue in less than a day out.
Half an hour later, all the case investigators who currently had no tasks gathered in the conference room.
Wang Song played a one-minute surveillance video.
“Based on the physical characteristics of Lu Chuan’s footprint identification and analysis, we screened all the videos passing by a supermarket and a dental clinic on the left and right sides of the community.”
Although there is no surveillance at the entrance of the victim’s community , but a supermarket and a dental clinic were opened on the left and right sides respectively.
This supermarket and dental clinic have their own surveillance equipment installed, which can capture street information passing by the supermarket and dental clinic.
Theoretically, if you enter the gate of the community where the crime occurred, the other party must pass through the supermarket or dental clinic.
Unless the suspect comes directly opposite the main entrance of the community, this way he can avoid the surveillance of supermarkets and dental clinics.
However, there is a lot of traffic at the entrance of the community, and there is a one-meter-high railing in the middle. The three people crossing the road attracted quite a lot of attention.
The other party will most likely not choose this method.
In addition, the other party does not know that there are surveillance cameras inside supermarkets and dental clinics, which can capture the situation on the street outside the store.
So, from a probability perspective, the other party should leave clues in these two surveillance cameras.
“Look at this guy!”
The person who appeared in the surveillance is a slightly fat middle-aged man.
“Before and after the incident, a total of more than 500 people’s surveillance videos were screened.”
Of course, this so-called screening was not completed by Wang Song alone.
In fact, before Wang Song arrived, the Tianzhou City Criminal Investigation Detachment had already discovered these two surveillance cameras, and used the information in these two surveillance cameras as important clues to investigate all personnel.
