Lone wolf attack

Self-planned mass murder by an individual

A lone wolf attack, or lone actor attack, is a particular kind of mass murder, committed in a public setting by an individual who plans and commits the act on their own. In the United States, such attacks are usually committed with firearms. In other countries, knives are sometimes used to commit mass stabbings. Although definitions vary, most databases require a minimum of four victims for the event to be considered a mass murder.
