A 75-page document tied to San Diego shooters Cain Lee Clark, 17, and Caleb Laim Vazquez, 18, called for the political system’s destruction and an “all out race war” after the pair killed three people Monday.
The writings preached anti-Islam, antisemitism and hatred toward Blacks, Latinos and LGBTQ+ people, and investigators say they drew heavily on the “great replacement” theory and earlier mass killers including Brenton Tarrant.
FBI officials said the teenagers met online, are probing how they were radicalized, and are examining a possible livestream from inside their BMW showing combat gear and Nazi symbols.
