Serial crimes are often premeditated. Perpetrators typically prefer to operate in familiar areas, adhering to the "three-no" principle.
Not too far, not too close, and no repeat locations.
Not too far means the perpetrator generally won't commit crimes in distant places, especially those they are unfamiliar with. This stems from a psychological need for a sense of security.
Not too close is also easy to understand. Committing a crime right on one's doorstep is high-risk, as it's easy to run into acquaintances. As the saying goes, "A rabbit doesn't eat the grass around its own burrow."
No repeat locations means the crimes will not occur in the same place. Any location where a murder has occurred will have heightened security, and the public will be more vigilant, increasing the risk for the perpetrator.
