Two teenage gunmen opened fire on Monday at the Islamic Centre of San Diego, California, killing a security guard and two other men outside the mosque before the suspects were found dead, apparently from self-inflicted gunshot wounds, police said.
San Diego Police Chief Scott Wahl said local law enforcement and the FBI were investigating the attack on the largest mosque in San Diego County as a hate crime.
However, no precise motive or precipitating incident for the gun violence has been publicly suggested by authorities.
All of the children attending a day school at the mosque complex were accounted for and safe after the shooting, which erupted at about 11:40am PDT (1840 GMT), officials said.
At an evening news conference, Wahl disclosed that the mother of one of the two suspects had called police about two hours before the shooting to report that her son, whom she described as suicidal, had run away from home, taking three guns she owned and her vehicle.
According to the chief, the mother said her son was with a companion and the two were dressed in camouflage. Police initiated efforts to track down the youths and were dispatching patrols to a nearby shopping mall and the son’s high school as a precaution when calls came in reporting the mosque shooting.
The chief declined to disclose the contents of a note he said was found by the runaway’s mother.
Prior to the shooting, police were not made aware of any “specific threat” to the mosque or any religious centre, school, shopping area, or any other place, Wahl said.
Police instead were confronting a case of “generalised hate rhetoric and hate speech,” which together with reports of a runaway teenager with multiple weapons wearing camouflage “triggered a much bigger threat assessment”.
The attack came the week before Eidul ADha and the Hajj pilgrimage.
“We have never experienced a tragedy like this before,” Taha Hassane, the imam and director of the Islamic Centre, told reporters. “It is extremely outrageous to target a place of worship.”
Scores of law enforcement officers called to the scene encountered the bodies of the three men affiliated with the mosque shot dead. Officials credited the slain security guard as likely having helped prevent further bloodshed.
A short time later, police discovered the bodies of two teenage males, aged 17 and 18, in a vehicle in the middle of a street, dead from apparently self-inflicted gunshot wounds. Police originally put the age of the older youth at 19.
Wahl said 50 to 100 police officers from across the San Diego area immediately responded to the first “active shooter” call and within four minutes had converged on the mosque, located in the residential-commercial Clairemont district of California’s second-most populous city.
Footage from local television stations showed dozens of patrol cars on a highway bridge, police in tactical gear armed with rifles perched on the roof of the mosque near its dome, and armed officers on the ground making their way through the complex.
Wahl said no shots were fired by law enforcement during the episode.
At about the time they were responding to the attack, shots were also fired at a landscaper a couple of blocks away, and investigators are treating the incidents as connected. The landscaper was not injured, Wahl said, adding that the man was wearing a helmet that may have deflected a bullet.
Five hours after the shooting, the police chief said investigators were still piecing together details of what may have ignited the violence and how it transpired.
The Islamic Centre is the largest mosque in San Diego County and houses the Bright Horizon Academy.
