There is still a lot of things they have to do now.

First: First, extract all the surveillance monitors around the wall, and perform a screen to check whether the suspect can be found.

Second: The apartment administrator gave the identity information of the owners who stayed in the apartment. They wanted to compare these people with those who entered and exited the apartment every day to see if there were people who did not belong to the apartment but came to the apartment that day.

Third: Shi Xinyu's record of Huang Shanshan's ID card was released, and they also needed to investigate the people who entered Huang Shanshan's room on the hotel that day.

Although they are all surveillance tasks, the workload of this job is actually very large, especially if you keep staring at a screen and keep watching so bored, it is really tired and boring. If you are not careful, you may be neglected.

Back to the bureau.

Zhong Tianzheng made a very simple work plan.

Shi Xinyu continued to check the surveillance of the hotel where Huang Shanshan was staying in. He personally checked the information of the people in the apartment and the surveillance personnel entering and leaving that day. This was the most difficult, so he had to check it himself.

As for the surveillance on the road, he distributed it and asked Ah Xiang to take the lead and take the other police officers to watch it. This surveillance only needs to find people in the corresponding time period. Although the number of surveillance monitors is large, the time period is clear and it seems that it is not inefficient.

"Let me check with Ah Xiang."

Shi Xinyu appeared in front of Zhong Tianzheng, and she spread her hands helplessly: "The surveillance cameras on the other side of the hotel are gone."

Zhong Tianzheng frowned: "Man-made damage?!"

"As long as the validity period is one month, the content in them will be gone in one month." Shi Xinyu shook his head helplessly: "Huang Shanshan last checked in a room was more than a month ago. In other words, this information can no longer be searched."

"Okay."

Zhong Tianzheng had no choice but to arrange them and took out all the tenants' check-in registration personal information copied from the apartment administrator, and took pictures of the portrait one by one.

"Si..."

Zhong Tianzheng reached out to light a cigarette, looked at the computer screen with his eyes squinted, and quickly tapped the right-click of the arrow key, and recorded the appearance of everyone who appeared on the screen.

At this time, he entered a very strange state again.

In the mind.

The grandmaster-level space conception power has constructed a space. The appearance of everyone who has appeared in front of him appears in the space, unfolding in rows downwards, forming a square formation.

The digital Zhong Tian was standing at a high place overlooking the characters appearing below, and couldn't help but be astonished.

He once again discovered the terrifying aspects of the grandmaster-level space conceptual power.

Anyone whom the people captured by one's own vision appeared one by one in the space of the master's level of space conception, as if a real person was standing in front of him, very real.

soon.

All the tenants who have registered the information for the entire building have been viewed.

Zhong Tianzheng opened the surveillance video at the entrance of the apartment copied by Axiang and started to play at twice the speed. He captured everyone entering and leaving, and then quickly compared with the people in the space. The efficiency was very high, just like a high-speed comparison machine.

Fortunately, the surveillance cameras installed in the apartment are all 1080P image quality ultra-clear cameras, and the image quality is pretty good, which relieves some of the pressure on Zhong Tianzheng to view the surveillance.

soon.

On the day Huang Shanshan died, all the surveillance of people entering and leaving the entire apartment building was checked.

During this day.

Among the people who appeared in the surveillance, there were twelve people in total. They did not belong to this apartment, but they had entered the apartment.

Among these twelve people.

Six of them belong to six express delivery companies, and they all left shortly after they came in. These people can be investigated first.

And among the remaining six people.

There were three people who left the apartment after about 10 o'clock that night.

This time period.
