The surveillance cameras showed that Lu Ning and Li Nian had indeed entered the alley one after another. This at least proved that Qian Shu and Li Lang had lied about not having seen Lu Ning.
However, the situation inside was unknown. This was because the surrounding area was an old neighborhood, and it was already not easy to find a surveillance camera that overlooked the road. Almost no one was managing this area, so it was even more impossible for there to be surveillance cameras inside civilian houses in the alleys.
Other than the three of them, only one person could provide a glimmer of hope in this matter; when the police were checking the surveillance cameras, they saw another man stop his car and enter the alley. It looked like he had chased after the two girls.
First, they retrieved the video and showed it to the two people making the accusations—both of them said they did not know him. Then, they showed it to Li Nian right after that.
