Zhao Dong was completely confident in Guan Feng's footprint identification and said, "In that case, it's not advisable to alert them for now. You need Gao Dacheng and the others to continue the investigation, especially the campus surveillance! Confirm Dean Chen's whereabouts during this period. You'll come with me to the monitoring center."

Guan Feng nodded and said, "With the detachment leader leading the way, I feel even more confident!"

Zhao Dong waved his hand and said, "Don't even try!"

The two headed straight for the city's monitoring center.

Fifteen minutes later.

The two arrived at the monitoring center building.

Director Wang, who was in charge of the monitoring center, immediately stepped forward, shook hands with Zhao Dong, the head of the criminal investigation detachment, and asked with a smile, "What brings Chief Zhao here?"

Zhao Dong introduced Guan Feng's identity: "This is Captain Guan from the Major Crimes Unit. He's here to investigate a murder case."

Director Wang was surprised by Guan Feng's age. Upon hearing that it was a murder case, his tone became serious, and he said to Zhao Dong, "Please come in! We have retrieved the relevant surveillance footage as you requested. As for the specific time, that depends on you!"

Zhao Dong nodded and followed Director Wang to a side hall.

This is a small room.

It's a small space of a dozen square meters, with a computer and a chair, and four large screens on the wall.

Guan Feng looked at the screens and after a moment locked onto two of the cameras.

Those are security cameras located outside the school park.

Guan Feng pointed to the two cameras and said, "Team leader, these are the two cameras!"

Zhao Dong said, "Director Wang, can we retrieve it now?"

Director Wang immediately said, "Sure! This area is now separate from the lobby, so it won't affect the surveillance. You can access it anytime."

Guan Feng didn't stand on ceremony and sat down to retrieve the information.
