Lu Chuan led the investigating detectives from the Criminal Police Brigade to the crime scene again.
"Bureau Lu, there is indeed no doubt at the scene. No obvious signs of climbing were found on the windows."
When Zhang Xiaoman discovered the body, he violently opened the door of the rental house. After Lu Chuan came to the scene to investigate again, he found that the door was locked from the inside.
In other words, after killing Chen Yaju, the criminal suspect not only locked the door from the outside, but also locked it from the inside.
This is a little strange.
If the criminal suspect locked the door directly in the house after killing Chen Yaju, then the only way for him to leave here is through the window.
But the only window in the room was only about 20 to 30 centimeters in length, width and height, which could not allow an adult to pass through.
Judging from the cause of death of the victim Chen Yaju and the injuries on her body, there is no doubt that the other party was an adult. .
And there is a high probability that he is a male
Since the other party is an adult male, it is impossible to escape through this window, and the on-line investigation police of the Criminal Police Brigade also specially looked at this window. It was covered with a layer of dust, and there were no traces of stepping on it. Although the wall was worn out, , but there are no traces of being stepped on.
Lu Chuan himself has seen the opening of this window and the Criminal Police Brigade. He has learned a lot from being with him for more than a year, and his technology can be said to have advanced by leaps and bounds.
This is also the main reason why Lu Chuan is assured that the other party will directly conduct on-site inspections.
The ground was very solid. Lu Chuan walked through every inch of the crime scene and found no hidden grids.
And according to the landlord, the solid building below had only one basement floor, and below that were some pipes and the original foundation.
It's even more impossible upstairs.
Because there are people living on the first floor upstairs.
Of course, it is impossible for the criminal suspect to lift the floorboard and escape upstairs, so there is no possibility in the sky or the ground that it is not locked.
This made everyone somewhat confused as to how the murderer left the room after killing someone.
As for this window, Lu Chuan had carefully observed that it could actually be automatically locked from the inside, which meant that if someone closed the window from the outside, the window would naturally be locked from the inside.
This is why Lu Chuan and the modern detectives of the Criminal Police Brigade are studying this window, because if the other party can leave the window and close the window outside, then the window will naturally become awkward. But the problem is that this window is too small to allow an adult to pass through, and there are no traces of stepping around it. So it is impossible for the other party to leave from here.
"What about footprints and fingerprints?"
Lu Chuan asked.
The report he received last night was that only the deceased, her husband Zhang Baohai and some footprints of her children were found in the room. Of course, these footprints are relatively blurry, but the equipment can still identify them, after all, it took too long.
"There are not many findings in terms of fingerprints. There are some vague fingerprints that are basically locked on Zhang Baohai."
"However, there are still some fingerprints that cannot confirm the identity of the owner. On the one hand, the fingerprints collected were too broken for too long. On the other hand, although the body of the deceased Chen Yaju was not completely decomposed, it is very difficult to extract the fingerprints on the fingers. Difficult, we have not done further comparison yet.”
Bu Chuan nodded. He rarely directly participates in technical work now, unless there is something extraordinary. Too much time has passed since the scene of these cases, and it is very difficult to extract some valuable clues and information. This is something I know better than anyone.
In addition, what the criminal police said now was only some vague footprints extracted at the scene. In fact, there were some clear footprints. For example, two people, Zhang Xiaoman and Wang Dapeng, broke into the door and actually caused a lot of damage to the scene.
The two men broke into the door without any sense of on-site protection and found the body rushing directly into the house. Inside, it was probably to confirm the identity of the corpse, and there were traces of them left everywhere in the room.
In addition, after the neighbors heard about the death here, many people came over. There were also some footprints left by these people in the house. Of course, it would be much better after the people from the police station came and sealed the scene.
As for the door, it is still relatively strong, and no traces of cutting or subsequent modification were found, which means that it is impossible for the other party to remove the door and then escape to create the illusion of a secret room murder.
Lu Chuan stayed here for more than an hour during the second on-site inspection, but did not gain much.
The investigation of the case seems to have reached a deadlock.
Chen Yaju's husband and daughter were originally suspected, but now the suspicion is basically very small.
The estrangement between Zhang Xiaoman and her mother is not just because the other party is suspected of seducing her husband.
Another important reason is that Zhang Xiaoman feels that her mother is in her 40s, but she is still not living a stable life, and even wants to elope with others, so they feel it is very embarrassing and they have never told outsiders about it. Afraid of being laughed at by others.
The reason why she didn't contact Chen Yaju was because she was afraid that the other party would really elope with her and she didn't know how to face this matter.
As for Chen Yaju's husband Zhang Baohai, it seems that he has more reasons to trust him, and the reason why he has not contacted Chen Yaju for half a year.
After all, his wife ran away and eloped with someone else, so it would be easier for the news to spread.
After Lu Chuan returned to the criminal police brigade, there was originally a suspected clue, but now there is a clue.
Wang Zhaokai and the others found two other men in Chen Yaju's mobile phone.
One or both of these two men may have a close relationship with Chen Yaju. The person Chen Yaju originally wanted to elope with may be one of these two men.
"Bureau Lu, these two people have been found."
In the office, Wang Zhaokai reported the situation.
"Chen Jiang has just brought these two people back, and then conducted the inquiry. What happened was that the two people were not very far from Chen Yaju's rental house. One lived above them, and the other was just a few steps away. In a community two to three kilometers away.”
When Lu Chuan heard this, his eyes lit up.
"What's the specific situation?"
"These two people were relatively cooperative during the inquiry. They did not hide the fact that they knew Chen Yaju. One of them had a relationship with Chen Yaju, and the two had transfer records."
According to what the other party said, this man promised Chen Yaju that he wanted to take her away from Haizhou City. Of course, he actually wanted to deceive him. However, the so-called elopement or marriage partner by Chen Yaju should be this man. (End of chapter)
