Among all types of crimes, random crimes are the hardest to solve.
Because random incidents leave very few clues behind, unlike meticulously planned cases. Meticulously planned cases seem to leave no useful traces, but actually, the more they do, the more mistakes they make.
To erase their traces, the murderer must do some things outside of the crime itself.
These actions, in fact, often provide the police with more investigative leads during crime solving.
More than a decade ago, Haizhou City experienced a series of vicious robbery-murder cases.
The suspect acted in a completely unpredictable manner, targeting different victims, stealing varying amounts of money, and committing crimes at different locations.
The police investigated all intertwining clues of time and space concerning the suspect but found no patterns, eventually concluding that the perpetrator acted randomly.
