Serial murder

Serial murder refers to the act of killing two or more people, typically over an extended period, with a cooling-off period between the murders. Unlike mass murder, which occurs in a single event, or spree murder, which involves multiple murders in a short timeframe without a break, serial murder is characterized by a pattern of criminal behavior. Serial killers often have psychological issues and may choose victims based on specific criteria. The motives can vary, including psychological gratification, power, or revenge, and they often elude capture due to their careful and calculated approach to committing crimes.
