Bab 2287: The criminal's identity

The command vehicle drove on the quiet road in the middle of the night. For safety's sake, two police cars followed behind.

"I found it!" Xu Qin held up her phone and told Zhao Yu,"the search team found a downward passage behind the ventilation room. They have already gone in to investigate. The passage is connected to the building's drainage system, and it is connected to a thousand meters away!

"Look ..." She showed the video on her phone to Zhao Yu and Ding Lan, then explained,"the search team said that this sewer is quite well-developed, so it obviously has other uses!"

"Oh ..." Zhao Yu looked at the video, then nodded and said,"it seems that there is really a problem with Mr. Li!" The sewers are either used to transport prohibited items or to escape!"

"The search team found some professional equipment inside, which can basically prove that the criminals entered the building from here," Xu Qin said.
