The next morning, Joel obtained the hallway surveillance footage from Capital University's security department.
The recording clearly showed Chen Lili entering the jewelry design classroom at 7:18 p.m., almost an hour after the last class had ended. She remained inside for six minutes before leaving with her phone in her hand.
Although there was no camera inside the classroom, the footage proved that she had entered when she had no legitimate reason to be there.
More importantly, she had lied when she signed the classroom access register.
According to the register, Chen Lili had left the jewelry design building at 6:11 p.m. and had not returned.
The university security department preserved the original recording. A certified copy was given to Mo Shian's intellectual-property lawyer, while another remained with the university.
Weiwei did not report Chen Lili immediately.
