Yuan Chen and the criminal police team also felt something was wrong. There were obvious signs of being tampered with at the crime scene, and all the cash on the two deceased persons was also taken away.
This was the scene of a robbery, but how did the murderer get into the rental house of Su Mei and Li Jiaojiao? This rental house only had a simple wooden door, but there was no sign of any damage or technical unlocking.
The two bolts of the door lock were open when Yuan Chen kicked it off. To put it simply, the door was locked from behind before Yuan Chen kicked it open.
"Secret room murder?" I blurted out the words from Conan.
"It didn't count at first, because it's possible that the murderer had the key to the house, opened the door to commit the murder, and then locked it when he left. After all, I've done something before where the victim lost his key and was picked up by the criminal and followed him into the house.
A robbery case." Yuan Chen pouted and said, based on the clues they had at the time, the only answer seemed to be that the murderer used a key to open the door and commit the murder.
The conclusion given by the forensic doctor is that the time when the two were killed should be from February 6th to February 9th, before the New Year's Eve to the third day of the Lunar New Year. If it is really like the case that Yuan Chen handled before, then we only need to investigate
Just check the people entering and exiting the small building between No. 6 and No. 9. Coincidentally, although this self-built small building is in a remote location, there are surveillance cameras looking down on the front, rear, left and right of the small building. This is
This means that as long as someone passes by this road, they will definitely not escape Yuan Chen's eyes.
"I have never seen such a wealthy surveillance agent in my eight lifetimes." Yuan Chen was confident and seemed to be able to find the murderer immediately.
On the morning of February 15th, Yuan Chen and his colleagues ran to Heping Village to collect surveillance. Before lunch, they had copied all the surveillance materials and brought them back to the bureau. Except for the gate of the small building and the three main probes at the front and rear,
He also made a copy of the security surveillance cameras in the surrounding areas, the anti-theft surveillance cameras at the supermarket entrance, and the ATM machine surveillance cameras. Yuan Chen didn't leave any blind spots, and he was very confident that he would be able to uncover the killer from the surveillance cameras.
But until 3 o'clock in the morning when Yuan Chen checked the surveillance for the seventh time, there was not even a decent suspicious object in the camera, let alone the murderer. There was a dead silence in the criminal police team. No one had ever handled such a case. Who could
I also couldn't understand how two living people could be killed without anyone noticing. The police never believed in perfect murder cases, but in the current situation, there seemed to be an invisible killer at the murder scene.
What a ghost!
When Yuan Chen was about to watch all the surveillance cameras again, his master, Old Shen, asked him to stop. "Stop looking, there is no murderer in the surveillance cameras." Old Shen patted him on the shoulder.
Lao Shen was from Sichuan, and he was the squadron leader of Yuan Chen in the criminal police team he joined after being transferred from the army. The two of them were transferred back to China in the same year. On the eighth day of the Lunar New Year, he was on the road. When he came back, he learned that a murder case had occurred in his jurisdiction.
.Lao Shen said that Yuan Chen was too impatient and didn't even know he was being played around by the murderer.
The police have different investigation methods for different types of cases, which are called "investigation ideas" in the words of reporters, but Lao Shen is willing to call them "routines". Sometimes using "routines" can greatly reduce the preliminary investigation work and improve efficiency. But there are
Sometimes being constrained by this kind of "routine" thinking will confuse the eyes of the police. Yuan Chen's original single-minded character is the easiest way to end up in a dead end in solving crimes.
When Lao Shen mentioned this, Yuan Chen thought of the strange thing about the knife wounds. These 11 wounds always made him feel a little uncomfortable, because if the murderer was him, then he would definitely not stab him like this. Lao Shen thought this was the killer.
A bureau was set up for the police to lead the police to the wrong road. Yuan Chen suffered in the team all night with full of discomfort.
How did the murderer enter the crime scene without leaving any traces?
............
"Why don't you come to me, kid? If you want to solve the case, come here." When the forensic doctor Old Ding yelled at Yuan Chen, he seemed to be yelling at his own son.
Lao Ding is the treasure of the criminal police team. The captain must be polite when he sees him. Generally speaking, big shots usually have bad tempers and like to be lazy. Regardless of men and women, this seems to be a common problem among excellent forensic doctors. If you let
If he appears on the scene in the middle of the night, he will definitely call in the new forensic boys. However, once the body passes through Old Ding's hands, he will definitely be able to provide you with many unexpected things.
"During the autopsy, I found that the murderer's murder method was very sophisticated. The victim's carotid artery was cut with two knives. He should have been a doctor, butcher or other specific knife-wielding profession, but there are also doubts about this knife edge. We found that Su Mei
The body of Li Jiaojiao was on top of Li Jiaojiao at that time. I speculate that the two were very close to each other at the time. The murderer probably killed Li Jiaojiao first and then the taller victim."
Everyone had seen the knife wounds on the corpse. Yuan Chen could only put his doubts in his stomach and feel uncomfortable, but Lao Ding saw more details from it and put forward speculations that could change the case.
There are specializations in a profession, that's the truth.
"Su Mei's other stab wounds were concentrated on the upper body, while Li Jiaojiao's 6 wounds were concentrated on the lower body. This is very likely that the murderer inflicted follow-up wounds on the two of them after they fell. Generally, follow-up wounds indicate that the criminal and
There was a huge conflict between the victims, and they used it to vent their anger. The stab wounds on Su Mei's body were in line with this characteristic, while Li Jiaojiao's last stab was very casual, but judging from the distribution area of the stab wounds, it was very much like covering up herself.
The anger was deliberate." Old Ding's words made Yuan Chen's discomfort disappear. Although there was no complete evidence, Yuan Chen had an unprecedentedly strong sixth sense.
The murderer was basically targeting Su Mei.
At 8:30 pm on February 16, Yuan Chen had just investigated the call records between Su Mei and Li Jiaojiao since February. As expected, Li Jiaojiao's main call recipients in February were parents and friends, and he did not find anything suspicious.
But Su Mei's recent call records are quite intriguing.
Su Mei has many more call partners than Li Jiaojiao, including small bosses, college students, white-collar workers, and gangsters, and they are all male. Living in Heping Village, there are generally two types of women who frequently talk to these men: one is
The other kind of promiscuous women like Zhao Li and Li Jiaojiao are called old bustards, and Su Mei belongs to the latter.
It was indeed a little late to find out the victim's occupation the day after the incident, but it was not too late. Disputes over prostitution, forced buying and selling, or even lack of "service" could all lead to homicide. The police had already prepared such cases long ago.
