Wang Gang!
The killer turned out to be him, the principal of the Experimental Primary School back then.
Qin Meili confessed quite a lot, and the Dark Fragrance Clubhouse she ran didn't just have Wang Gang as a client.
But speaking only of this case, since Qin Meili had already come clean, there was no need to wait until the next day.
That very night, Wang Gang was dragged out of his own bed by the police and taken in.
In the interrogation room, Wang Gang was still wearing his pajamas, with handcuffs on his wrists.
As for killing Zhang Mengyao back then, Wang Gang made a full confession.
According to Wang Gang, that year when Zhang Mengyao left school she didn't go home; she was waiting for him at a deserted spot outside the school.
"Zhang Mengyao had only just started working when I took a fancy to her, but I was the principal, it wasn't possible to just say something to her directly. The people from the Dark Fragrance Clubhouse got her for me."
