Two teenage gunmen opened fire outside the Islamic Center of San Diego on Monday, killing three men before fleeing and fatally shooting themselves in a parked car blocks away, an attack police are now investigating as a hate crime after discovering anti-Muslim writings and hate speech scrawled on a firearm.
Five people died in total: the three victims outside the mosque and the two suspects, who were found dead from apparent self-inflicted gunshot wounds in a white BMW. San Diego Police Chief Scott Wahl told reporters that officers arrived on scene just four minutes after the initial call, calling the response "the most dynamic and impressive response I have ever seen in policing" across his 28 years in law enforcement.
Among the dead was Amin Abdullah, a mosque security guard whose actions Wahl credited with preventing a far worse outcome. The chief did not mince words about what Abdullah did before he was killed.
The timeline that emerged from police briefings reveals a grim sequence, and a narrow window that closed before anyone could stop the attack.
Around 9:42 a.m., San Diego police received a call from a concerned mother reporting a runaway juvenile. Breitbart reported that the mother told police her son was missing, suicidal, and possibly armed, with weapons and her vehicle gone from the home. Officers began searching and elevated the threat level after speaking with her.
Roughly two hours later, at 11:43 a.m., dispatchers received reports of an active shooter at the Islamic Center of San Diego on the 7000 block of Eckstrom Avenue in the Clairemont neighborhood. Officers arrived by 11:47 a.m. and found three adult men dead from gunshot wounds outside the center.
They immediately entered the building and an adjacent school to hunt for the shooter. No children were physically harmed.
At 11:52 a.m., new calls came in from the 7100 block of Salerno Street, just two blocks away, reporting that a landscaper had been shot at from a passing vehicle. The landscaper survived; the bullets missed.
Minutes later, officers were directed to the 3800 block of Hatton Street, where they found the white BMW stopped in the road. Inside were the two suspects, both dead. By 1:06 p.m., the San Diego Police Department posted on X: "The threat at the Islamic center has been neutralized."
Police would not clarify whether the runaway juvenile call was connected to one of the suspects. That gap in the public record remains open.
A law enforcement source identified the suspects as 17-year-old Cain Clark, a wrestler at Madison High School, and 18-year-old Caleb Velasquez. The New York Post reported that investigators found anti-Islamic writings, anti-Muslim hate messages, and racial pride language in what appeared to be a suicide note. Hate speech was also found written on a firearm.
Chief Wahl confirmed the hate crime angle publicly. Just The News reported Wahl telling reporters:
"At this point, there was definitely hate rhetoric that was involved."
The FBI is assisting in the investigation. Police have not yet disclosed how many firearms were recovered, which weapon bore the hate speech, or the identities of the two other victims killed alongside Abdullah.
The attack bears a disturbing resemblance to a recent attack on a Michigan synagogue in which a suspect rammed a vehicle into the building and exchanged gunfire with security, another strike against a house of worship where armed protection proved decisive.
Wahl reserved his most pointed praise for Amin Abdullah, the security guard who was among the three killed outside the mosque. The chief said Abdullah "played a pivotal role in assisting" and that without his actions, "this could have been worse."
AP News reported Wahl's fuller assessment of Abdullah's conduct:
"It's fair to say his actions were heroic. Undoubtedly he saved lives today."
Police did not detail exactly what Abdullah did, but the implication was clear: the guard confronted the gunmen and bought time for others inside the center and the adjacent school. No children were physically injured in the attack.
The episode is a stark reminder that armed security at vulnerable institutions is not a luxury, it is often the last line between a targeted attack and a mass casualty event. Across the country, deadly shootings targeting religious communities and public institutions have forced congregations and organizations to invest in protection that government alone cannot provide.
San Diego Mayor Todd Gloria issued a statement Monday night:
"Today, our city was shaken by a violent act at the Islamic Center of San Diego and my heart is with every person touched by this tragedy. No one in our city should ever have to fear for their safety in a house of faith and a place of learning."
Gloria also thanked the San Diego Police Department, fire-rescue personnel, and every first responder "who moved toward danger to bring this threat to an end."
Wahl struck a similar tone, telling reporters: "All of our kids are safe. Our hearts go out to the families who, in this moment, are being notified of what has happened to their loved ones."
The mosque's imam told reporters that there was no ongoing threat but urged people to stay away from the Islamic Center of San Diego while the investigation continued. The site was closed for the rest of the day.
Several questions remain unanswered. Police have not publicly confirmed whether Clark or Velasquez was the subject of the earlier runaway juvenile call, or whether the two-hour gap between that call and the shooting represents a missed opportunity to intervene. There is also a discrepancy in the suspects' reported ages: initial accounts described the pair as 17 and 18, while a police timeline entry referenced a 17-year-old and a 19-year-old. Authorities have not resolved the inconsistency.
Investigators have not disclosed how the suspects obtained their weapons, how many firearms were used, or whether any prior contact between the suspects and the mosque existed. The nature of the "generalized hate rhetoric" Wahl described, whether it pointed to an organized ideology or a more diffuse radicalization, also remains unclear.
The broader pattern of targeted violence against faith communities, from high-profile shooting cases that raise troubling questions about warning signs to incidents that leave neighborhoods reeling, makes these unanswered questions more than procedural loose ends. They matter for prevention.
With both suspects dead, there will be no criminal trial. That makes the investigative phase all the more important. The public deserves to know whether the warning signs were missed, whether the two-hour gap between the mother's call and the massacre could have been closed, and whether any system, school, social media, law enforcement, had earlier contact with the suspects that should have triggered intervention.
Hate-fueled violence against any house of worship is an attack on the religious liberty that sits at the foundation of American life. Conservatives understand this. The right to worship freely, whether in a mosque, a synagogue, or a church, is not negotiable, and those who target it deserve the full weight of public condemnation regardless of the victims' faith.
The heroism of Amin Abdullah, a man who stood between armed attackers and the people inside his mosque, deserves to be remembered long after the news cycle moves on. His willingness to confront danger is the kind of courage that communities scarred by sudden violence need, and that no policy paper can replace.
Three men went to a house of worship on a Monday morning and never came home. A security guard gave his life so others could keep theirs. The least their city owes them is a full accounting of how it happened, and an honest reckoning with what, if anything, could have stopped it.
