Authorities investigating the deadly shooting at the Islamic Center of San Diego said that the two teenage suspects, identified as Cain Clark and Caleb Vazquez, allegedly left behind a 75-page manifesto filled with racist, antisemitic and anti-Islam rhetoric.
The document, titled 'The New Crusade: Sons of Tarrant,' referenced mass killers, extremist ideology, and even Donald Trump, and praised white supremacist violence.
Federal investigators are treating the shooting as a likely hate crime, and are reviewing electronic devices, online activity, and social media accounts to determine how the suspects became radicalized.
The suspects, 17 and 18 years old, died from apparent self-inflicted gunshot wounds after fleeing the scene, leaving three people dead.
The victims, Amin Abdullah, Mansour Kaziha, and Nadir Awad, have been praised by community leaders and police for helping prevent a far larger massacre.
