Teens Shoot Up San Diego Mosque, Killing 3 - Here's What to Know

Three men were shot and killed Monday outside the Islamic Center of San Diego (ICSD) in what authorities are investigating as a hate crime, marking one of the deadliest attacks on a US mosque in recent memory. The two teenage suspects, identified by law enforcement as 17-year-old Cain Clark and 18-year-old Caleb Vazquez, both from San Diego, were subsequently found dead in a nearby vehicle from apparent self-inflicted gunshot wounds.

Police received the first reports of an active shooter at 11:43 a.m. at the mosque, located in the Clairemont neighborhood roughly eight miles north of downtown. Officers arrived within four minutes to find three men already dead in front of the building. The victims were a mosque security guard and two staff members of the Al Rashid Weekend School, an Islamic studies and Arabic language school housed within the ICSD complex.

"It is extremely outrageous to target a place of worship. Our Islamic centre is a place where people come to pray, celebrate and learn."

The security guard's heroism

San Diego Police Chief Scott Wahl called the security guard's actions "pivotal" and said he likely prevented greater loss of life. "At this point, I think it's fair to say his actions were heroic," Wahl told reporters. "Undoubtedly, he saved lives today." None of the students, teachers, or school staff inside the complex were among the victims, the imam confirmed all were safely evacuated.

Hate crime evidence

Investigators found anti-Islamic writing inside the BMW where the suspects were later discovered dead. Hate speech had also been inscribed directly on one of the firearms used in the attack, according to multiple law enforcement officials. One of the suspects left a suicide note at home that contained writings referencing racial pride. A firearm used in the shooting had been taken from a parent's home.

The mother of one suspect had called police Monday morning, before the attack, to report her son missing along with her car and her firearms. She told dispatchers her son appeared suicidal and had left a note. Officers were already speaking with her when reports of the shooting began coming in, and they immediately responded to the mosque.

"We are actively investigating this as a hate crime," Chief Wahl said at an evening press conference. "There was definitely hate rhetoric that was involved." No officers discharged their weapons during the incident; bomb technicians later cleared the suspects' vehicle.

Political and community response

President Donald Trump and California Governor Gavin Newsom were both briefed on the shooting. San Diego Mayor Todd Gloria pledged that "no resource will be spared" to protect religious institutions, telling the Muslim community: "Hate has no place in this city." Los Angeles Mayor Karen Bass called the attack "outrageous and heartbreaking," noting it occurred on the first day of Dhul Hijjah, a sacred period in the Islamic calendar.

The NYPD announced increased patrols at mosques across New York City. The Los Angeles Police Department similarly deployed additional officers to mosques and Islamic centers throughout the region. The Council on American-Islamic Relations (CAIR) condemned the shooting as a "horrifying act of violence" and said no one should fear for their safety while attending prayer or school.

The FBI is assisting San Diego police. San Diego County District Attorney Summer Stephan said state prosecutors are also involved. The ICSD announced it will remain closed until further notice, describing it as "an extremely painful and traumatic day for our congregation, students, staff, and the broader San Diego community." The center said counseling resources will be shared in the coming days.
