It's indeed not enough to suggest there's an issue with Xu Zhao's parents' company, but seeing Xu Zhao's name here, it's hard not to connect everything through these documents.
Zhao Kehan looked grim, saying, "So, is there possibly a fourth killer?"
He continued to review the documents of Su Chen's roommates.
Sheng Qin is not worth discussing, being the wealthy daughter of the Sheng Family, with no grievances against the people in dorm 4508, she lacks the motive for committing a crime.
Tu Weiwei also has nothing to do with dorm 4508; she has been quite plain from childhood, with nothing noteworthy that would catch Zhao Kehan's attention.
It wasn't until he turned to Sun Ling's file that Zhao Kehan suddenly stood up, startling those around him.
"Captain Zhao, what's wrong?"
"Did you discover any new clues?"
"Is there really a third killer? Who could it be?"
