The Definition and Characteristics of Serial Killers

A serial killer is defined as an individual who commits at least three murders over time, with a cooling-off period between the acts. This distinct definition highlights crucial differences from spree killers or those who kill within a specific timeframe, such as soldiers. Serial killers often exhibit specific patterns in their choice of victims or modus operandi, which can be dictated by psychological factors. Understanding these characteristics helps clarify how serial killers operate and why they might go undetected for extended periods.
