List of rampage killers (familicides in the Americas)

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.
