How do serial killers differ from mass murderers in terms of number of victims and timing?

• A. Serial killers kill four or more victims in one location across minutes
• B. Serial killers kill four or more victims on separate occasions
• C. Mass murderers kill four or more victims on separate occasions
• D. Mass murderers kill four or more victims in a single location

Answer: (B)

The key idea is how the killings are spaced in time and place. Serial killers conduct four or more murders across separate occasions, with a cooling-off period between each act. This means the murders happen at different times and often in different locations, over an extended period. Mass murderers, by contrast, commit four or more victims in a single location during one extended event, with little to no break between killings. So the statement about serial killers being four or more victims on separate occasions best captures the defining timing pattern. The other descriptions mix up the timing or location—for example, suggesting a single location or a single event for serial killers, or multiple occasions for mass murderers.
