2026 Islamic Center of San Diego shooting

On May 18, 2026, a shooting occurred at the Islamic Center of San Diego (ICSD), the largest mosque in San Diego, California, United States. Two teenage gunmen, identified as 17-year-old Cain Lee Clark and 18-year-old Caleb Liam Vazquez, fatally shot a security guard and two staff members outside the mosque before fleeing. Subsequently, they shot at a landscaper in a drive-by shooting and committed suicide in a nearby neighborhood. Clark and Vazquez recorded a live video of the shooting, and a racist manifesto that appeared to have been written by them was found online during investigation. Authorities said the incident is being investigated as a hate crime.
