Zhang Manyu!
After Zhang Manyu's remains were discovered, the police immediately launched a background investigation into Zhang Manyu herself.
The person who reported Zhang Manyu missing back then was her parents.
Of course, besides her parents, when Zhang Manyu disappeared, she also left behind a 9-year-old daughter.
But unfortunately, Zhang Manyu's daughter went missing three years ago after accidentally falling into the North River.
This means Zhang Manyu's only close relatives now are her parents.
And the two elderly are already in their 60s, in poor health, making it impossible for them to commit such a meticulous crime.
Moreover, if the two elders knew back then that Zhang Manyu was murdered rather than missing and knew who harmed their daughter, how could they do nothing?
So with Zhang Manyu's parents incapable of committing the crime and no other close relatives, who would seek revenge for Zhang Manyu?
