In the corner of the living room of Apartment 2084, cameras mounted on tripods flickered. Technicians from the Forensic Science Division bustled about, collecting evidence.
There was scarcely any room to stand indoors. Officer Wang Fengnian, his face grim, stood in the corridor discussing the case's progress with his colleagues.
"According to surveillance records from the elevator and hallway cameras, a man in a yellow and black delivery uniform arrived on the 20th floor at 15:43. He first knocked on the door of Apartment 2082 and, after speaking with a young man for about ten seconds, proceeded to Apartment 2084. Under the guise of delivering food, he got Zeng Weiming to open the security door," a young operative reported.
"After the security door was opened, the man quickly covered Zeng Weiming's mouth, entered the apartment, and closed the door. Until 19:24, when you, Officer Wang, opened the security door, no one else entered or exited Apartment 2084.
