Compared to the substantial evidence discovered at the crime scene investigation, the progress of the field team's interviews and inquiries was quite unsatisfactory.
The neighbors upstairs, downstairs, and next door all reported that they hadn't seen anything suspicious recently, and they weren't very familiar with Yang Qianqian, who lived there.
The surveillance equipment in the residential area had only one camera at the main entrance, but its clarity was not high.
The field team had gone to the property management office to make a copy, and the details still needed to be analyzed back at the station.
The crime scene investigation team collected so much that it took them the entire afternoon to finish up.
After sealing off the scene, the members of the criminal investigation team returned as the sun had already set; it was already past 6 PM when they reached the station.
