Relatives of victims killed in the Islamic Center of San Diego shooting called for stricter rules governing online platforms after investigators linked the teenage attackers to extremist digital communities.
Three worshippers died Monday when Cain Clark, 17, and Caleb Vazquez, 18, opened fire at the mosque before taking their own lives. Families joined civil rights groups urging lawmakers and technology companies to curb dissemination of hate material that can accelerate radicalization.
FBI agents are analyzing online writings attributed to the suspects that contain antisemitic and accelerationist ideology. Discord said it cooperated with law enforcement by preserving relevant account data. Anti-Defamation League analysts said attackers increasingly stage violence for online audiences.
Community vigils drew hundreds of mourners across San Diego County. CAIR-California said it was disturbed but not surprised that anti-Muslim hate appeared to motivate the assault. Elected officials pledged support for the congregation while debating whether platform liability reforms could prevent similar attacks.
Mark Remily said investigators are analyzing manifesto material to prevent future attacks and understand how the teenagers became radicalized. Hussam Ayloush of CAIR-California said the Muslim community expected hate-motivated violence given rising anti-Muslim rhetoric nationwide. San Diego’s Islamic center houses the region’s largest mosque and an affiliated school serving hundreds of families.
