This is a list of mass or spree killers in the Americas, excluding the United States that committed a familicide. A mass murderer is typically defined as someone who kills three or more people in one incident, with no "cooling off" period, not including themselves. [1] [2] A mass murder typically occurs in a single location where one or more persons kill several others. [3] [4] [5]
The victims must have been largely the relatives of the perpetrator to be considered a familicide.
This list does not include serial killers, members of democidal governments, or major political figures who orchestrated such actions.
