Chen Jiang continued to operate the projection and the screen was enlarged.
"But he did not take the elevator, but entered the stairwell, and then he never appeared again. Until the time of the crime, we never found out that this person appeared in the surveillance."
"Also, everyone, please pay attention. This man has three bottles of pure water in his hand, which is the brand of pure water found on the roof of our crime scene."
Damn it!
Everyone was excited.
In the surveillance video, this person entered the corridor from the 17th floor, holding three bottles of pure water found at the crime scene.
What's going on?
"How was the subsequent investigation?"
someone asked anxiously.
“Very interesting.”
Chen Jiang started operating monitoring.
"Dead. This person disappeared in the corridor on the 17th floor and never appeared in the surveillance again, so we started to investigate the surveillance of the entire building. Find out where he went."
"The interesting result is that we checked the surveillance cameras in the entire building. During that time period, no surveillance cameras captured the existence of this person, which means that the other party has the possibility and time to commit the crime. If the other party was in the corridor on the 17th floor After entering the ventilation duct and reaching the rooftop, there is really no surveillance that can capture him during this process.”
Chen Jiang continued to explain.
"We guessed that the other party might have been prepared. In fact, although Tang Meijuan jumped to her death three days ago, the suspect had already committed suicide a day in advance to avoid surveillance or police investigation. Have you entered the rooftop through the ventilation duct one day in advance and waited?”
"We will continue to investigate this possibility. If this possibility is true, then the other party should have stayed on the rooftop for one night. After contacting Tang Meifang on the second day, he left Tang Meifang alone. Appeared on the rooftop, Then kill the other person.”
"But there is a problem here. The relevant police station personnel and us arrived at the scene very soon after Tang Meijuan committed suicide. In other words, it is impossible for the other party to stay on the rooftop during this time period. He has passed through the ventilation system The pipe left.”
The faster Chen Jiang spoke, the more excited he became
"So if the other party left the rooftop after Tang Meijuan's death, then he is likely to reappear in the ventilation duct on the 17th floor about half an hour after Tang Meijuan's death."
"But we investigated the surveillance video in the corridor after Tang Meijuan's death and found no suspicious persons. This means that the suspect most likely did not appear in the corridor after coming out of the ventilation duct on the 17th floor, but left along the stairs. "Yuanyuan Building"
"But..."
As Chen Jiang said, he opened another surveillance video.
"The monitoring arrangement in your distant building is very complete. Although there is no monitoring between each floor in the corridor, there is a monitoring on the top floor, which is the 22nd floor, leading to the rooftop, and on the negative 1st floor, which is the underground parking lot. There is also a surveillance camera at that location in the garage. Take pictures of everyone who comes out of the stairs and enters the garage. Everyone, watch this surveillance camera.”
The monitoring time showed that about 45 minutes after Tang Meijuan's death, a figure appeared and flashed past the monitoring room. "We reviewed the entire surveillance data and found that this person came out of the stairway after Tang Meijuan's death. This person appeared in the garage on the first floor. Although the quality of the surveillance picture is not very good, we finally found it. Got this.”
Monitoring the quality of the picture, due to lighting and lighting reasons, the figure photographed at the stairway on the negative 1 floor is a bit blurry. It can only be seen clearly that the other person is probably wearing black clothes, but because he is also wearing a hat, his cheeks are not See clearly.
"If the other party leaves from the negative 1 floor, there are only two ways to leave the building. Either he returns to the lobby and leaves through the main entrance, or he drives away, because the garage on the negative 1 floor cannot allow pedestrians to pass. Yes, you can only drive away.”
"Then we checked after the other party appeared in the garage on the negative 1st floor. All the vehicles that drove out of the far building after that time period found an interesting thing. Look at this car."
This time it is not a surveillance picture, but a high-definition photo, which is exactly the photo exported from the parking lot management system. It's a Mercedes-Benz SUV.
"Only the license plate number is captured in this photo, but the driver is not captured. Are you sure he is this person?"
someone asked.
Chen Jiang shook his head: "This is the photo we just discovered this morning. The reason why we locked this photo is because we didn't confirm it at the beginning because the camera in the parking lot couldn't capture the driver's face, let alone minus 1 There was only one figure in the building’s surveillance camera, and the other person’s face was not captured, but this car is very special.”
"This car is the car of the boss of the engineering company where Tang Meijian works."
Um?
Many people suddenly became alert.
Check out the 16-9 book bar and see the correct version!
"No, didn't this boss say he didn't go to the company that day? Why was his car suddenly driven out that day?"
"Yes! According to our preliminary investigation results, the boss of this company never came to the company after work on the second day. Instead, he said he had been at the construction site. However, this person's car drove out after Tang Meijuan's death. The underground parking garage of Yuanfang Building, so we conducted a detailed investigation on the boss’s actions and found that he did not go to the construction site at all!”
"Furthermore, we compared the figure of the figure found in the surveillance camera on the negative 1st floor to be very similar to the figure of the boss of the engineering company where Tang Meijuan works, so we initially judged from the clues currently known that this project where Tang Meijuan works The boss of the company is most likely the suspect.”
"That's not simple. Didn't we find a hair in the ventilation duct? The DNA verification has been completed. Bring this person over and take a blood test to directly verify the DNA. We will know, and there is also pure water!"
"We also extracted some DNA information from the pure water, and compared it with him. If it is him, then the water should be what he drank, and then he will not be able to run away."
Chen Jiang nodded and looked at Lu Chuan.
"Bureau Lu, we also mean to investigate this person directly."
In fact, Chen Jiang and the others don't have time now, otherwise their group would go directly to investigate and extract the relevant information.
But it's not too late now, as long as the identity of the other party is confirmed and the investigation is done, it only takes a matter of minutes. (End of chapter)
