In less than two days, Jiang Yuan and his team had matched all the fingerprints and footprints involved in the factory area.
They ruled out footprints that clearly did not match Huang Shuijing's height, age, weight, and health level. The owners of the remaining footprints totaled three people and were soon confirmed; one was a local scavenger, one a resident nearby, and another a worker from a nearby construction site.
For the police, this was an expected but also relieving outcome. After all, if a daring adventurer had indeed decided to take a dump there, it would have been hard to make sense of it.
On the other hand, the remaining footprints and fingerprints were being matched one after another.
During the investigative phase, conclusive evidence is often sufficient, but as this case progressed to the litigation stage, Qinghe City's prosecutors followed, necessitating more comprehensive information.
