Team Leader Zhou didn't waste a moment, heading out to bring Tang Weili back to the police station.
If there were no direct suspects in contact, the police might consider surveillance. However, Tang Weili was the victim's ex-boyfriend, which was a highly specific connection, immediately raising the degree of suspicion to 8 million.

On the other hand, although the case wasn't a locked-room murder, it was certain that the murderer had meticulously planned the killing.
The method of murder was fundamentally different from victims being stabbed or hit on the back of the head with a blunt object.
While stabbings or clubbings could be explained as crimes of passion, of course, a court might not accept this; but during a police investigation, as long as you act within the limits of the law, there's no need to think like the law.
