Could This Be the Truth? (2 in 1)

Mr. Wang told Chen Ge about the serial killings that happened twenty years ago. Part of the details matched the information that Chen Ge already knew of the crime. For example, the killer once drowned the victim at Eastern Jiujiang Dam. Then, the killer lured the victim into White Dragon Tunnel and strangled him inside the tunnel, and there was a citizen who saw the killer push the victim from the edge of a tall building. Due to the long distance, the witness did not get a clear look of either the killer or the victim. However, in each case, the victims were children of a very young age. They wore different clothes, but their body size and height were extremely similar. It gave off the inscrutable feeling that the same child had been killed multiple times.
