The pair “didn’t discriminate on who they hated,” Mark Remily, the lead FBI agent in San Diego, said Tuesday.
The writings, obtained by The Associated Press, include hateful rhetoric toward Jewish people, Muslims and Islam, as well as the LGBTQ+ community, black people, women, and both the political left and right. Both express beliefs that white people are being eliminated, and one writes about mental health struggles and being rejected by women.
Investigators also found at least 30 guns, ammunition and a crossbow at two residences after Monday's attack in San Diego and were trying to uncover whether the shooters had broader plans, Remily said. The shooters, Cain Clark, 17, and Caleb Vazquez, 18, killed themselves, according to police.
Family of the two teens could not immediately be reached for comment.
