Lu Chuan believed that the reason for the crime was possibly committed by a local person or someone who had lived in the area for some time, was simple: the disposal site chosen by the perpetrator.
Although Lu Chuan had not been to the scene, photos in the file showed that the section of the sewage river where the killer disposed of the body was not open-air. The section where the body was disposed of was an underground river, some distance away from the open-air section.
If it weren't for a dog owned by a cleaner that bit through the box containing the body and pulled out a piece, this case might not have been discovered at the time.
Thinking about it, Lu Chuan had nothing much to do, so he took out the photos to study again.
However, after looking for a long time, Lu Chuan shook his head. Without fingerprints, it was really hard to handle.
