After Wang Zhonghai was caught by the police and brought to the station, he rambled about being abused by Situ Shuangshuang and the other two women. He admitted to the twisted acts of capturing, abusing, and killing women—he had no choice but to confess, as the evidence was irrefutable and left him with no room to deny.
Wang Zhonghai was nothing but a depraved scum. He wasn't someone with any honor or integrity, so after admitting his crimes, he easily ratted out the driver who sold him the girls.
The driver's surname was Han, his name Han Dong, and he was from the same village as Wang Zhonghai. They grew up together, sharing similar vices and getting along well.
Han Dong, unlike Wang Zhonghai, had no penchant for abusing women, but he loved money and was willing to do anything for it. As one of Wang Zhonghai's rare friends, Han Dong was aware of Wang Zhonghai's habit of abusing women.
