Domestic right-wing extremists have killed over 300 people in the United States in the last 10 years, a new study finds, with a deadly attack at a Walmart in El Paso, Texas, closing out a decade marked by white nationalist terror.

There were 42 murders in the U.S. committed by extremists in 2019, according to the Anti-Defamation League’s annual “Murder and Extremism” report published Wednesday. Of those murders, 38 were committed by people subscribing to far-right ideologies.

The bulk of last year’s domestic extremist murders occurred during the August massacre at a Walmart in El Paso, when a 21-year-old white man — who allegedly posted a racist screed online about the white nationalist “great replacement” conspiracy theory — shot and killed 22 people in one of the deadliest anti-Latino hate crimes in American history.

There was also the April 2019 shooting at a synagogue in Poway, California, when a 20-year-old man opened fire on a crowd of about 100 parishioners. He killed one woman and injured three others before his gun jammed. He later called 911 and reportedly told the dispatcher that Jews were trying to “destroy all white people.”

These murders, according to the ADL’s report, helped make 2019 the sixth-deadliest year for extremist-related violence since 1970. The four preceding years, from 2015 to 2018, were four of the five deadliest years on record for extremist violence in the U.S.

All told, domestic right-wing extremists murdered 330 people from 2010 to 2019. According to the ADL, that number accounts for 76% of the 435 domestic extremist murders during that time.
