March 22, 1978 - Benjamin Nathaniel Smith

Smith carried out his attacks over a holiday weekend, targeting victims across two states in a methodical progression that left two people dead and nine wounded before he turned the gun on himself. His actions were directly tied to his membership in the World Church of the Creator, a white supremacist organization whose ideology explicitly framed racial and ethnic minorities as targets. The span and coordination of the violence — three days, multiple cities, victims selected by identity — distinguished the rampage from more impulsive acts of hate-motivated violence.

During the weekend of July 4, 1999, white supremacist Benjamin Smith targeted ethnic and racial minorities (with victims including nine Orthodox Jews, two African-American men, and a Korean man), in a three-day drive-by shooting rampage in the U.S. states of Illinois and Indiana, after which he committed suicide.
