For three consecutive days, the police station, the criminal investigation department, and several assisting departments have been operating around the clock.
Autopsies, crime scene analysis, interviews and investigations, searching for the initial crime scene, the murder weapon, the victim's social network; even Su Qing's old classmates from his transferred school days were under secret investigation.
But unexpectedly, not a single clue emerged; whether it was the autopsy or the crime scene analysis, there were no leads.
This time, the killer was exceptionally well-prepared, leaving not even a single fingerprint; they couldn't even find the initial crime scene. The police speculated that the initial crime scene wasn't nearby, and perhaps the killer drove over to dump the body. However, there were no suspicious vehicles found when reviewing surveillance footage, let alone the murder weapon.
