Teenage shooters kill 3 at San Diego mosque, die by suicide; hate crime investigation ongoing
Consensus Summary
On May 19, 2026, two teenagers, Cain Clark (17) and Caleb Vasquez (18), opened fire at the Islamic Center of San Diego, killing three men—Amin Abdullah (51), a security guard, Mansour Kaziha (78), a mosque elder, and Nadir Awad (57), a neighbor—before dying by suicide in a nearby vehicle. The attack occurred hours after the mother of one shooter called police, warning her son was suicidal and armed. The shooters, radicalized online, left behind writings expressing broad hatred toward Muslims, Jews, LGBTQ+ individuals, Black people, and other groups, leading authorities to classify the incident as a hate crime. Security footage and police accounts confirm Abdullah engaged the shooters, activated lockdown protocols, and delayed their entry, saving the lives of 140 children inside the mosque’s school. Investigators recovered 30 firearms, a crossbow, and tactical gear from the shooters' residences, with the FBI and San Diego Police continuing to piece together their motives and connections. The tragedy has reignited debates about Islamophobia and gun control in the U.S., with political figures and Muslim advocacy groups condemning the violence and calling for stronger protections for places of worship.
