Details Emerge on San Diego Mosque Attack and Gunmen's Background
Background of the Attack
Recent court documents reveal that law enforcement had previously attempted to confiscate firearms from the residence of one of the attackers involved in the tragic shooting at the San Diego Islamic Center. This occurred over a year prior to the incident, following concerns regarding his mental health and extremist ideologies. The assailants, Caleb Liam Vazquez, aged 18, and Cain Clark, aged 17, executed the attack on a Monday, resulting in the deaths of three individuals before they were later discovered deceased from self-inflicted injuries. Investigators reported that the duo had planned a mass shooting at the mosque but were initially thwarted by a security guard. This guard, along with others in the parking area, alerted worshippers and emergency services, actions that are believed to have prevented additional casualties.
Legal Actions and Concerns
According to filings in the San Diego Superior Court, police in Chula Vista sought a gun violence restraining order against Vazquez's father, Marco Vazquez, in January 2025. An officer noted that the teenager had exhibited "suspicious behavior idolizing Nazis and mass shooters." This request was prompted by reports of online writings attributed to Vazquez. Authorities utilized a California law enacted after the Isla Vista shootings in 2014, which permits courts to temporarily restrict firearm access for individuals deemed a danger to themselves or others. Court documents indicated that Vazquez had previously been subjected to a "5150 hold," allowing for involuntary psychiatric evaluation for 72 hours.
Family's Response and Investigation
Police also highlighted that Marco Vazquez possessed several firearms and initially denied officers access to inspect their storage. In a court declaration, he asserted that the weapons were secured in a locked safe, inaccessible to his son. He expressed awareness of the serious allegations against Caleb, stating that he and his wife had proactively removed all firearms and sharp objects from their home. Marco later confirmed that he had transferred 27 of his firearms and two belonging to his wife to a licensed dealer for safekeeping. He denied any support for violent extremism, stating, "I never threatened anyone or supported any violent ideology such as Nazism, racism, school shootings, or mass shootings." The family claimed to have been monitoring their son's online activities and collaborating with his school to ensure he attended therapy regularly.
FBI Involvement and Radicalization
A law enforcement source disclosed that the FBI had been made aware of Vazquez's behavior prior to the attack, although the agency has refrained from commenting publicly. An investigation by a major news outlet revealed that both suspects had reportedly been radicalized through online extremist networks associated with white nationalism and neo-Nazi beliefs. Authorities indicated that the attackers left behind a 75-page manifesto filled with anti-Islamic and antisemitic sentiments, alongside calls for violence and societal upheaval. The writings reviewed by investigators included racist and anti-LGBTQ rhetoric, as well as admiration for past mass shootings and extremist groups. One excerpt allegedly linked to Vazquez advocated for "all-out race war for the purpose of societal collapse." It was noted that Vazquez had previously attended High Tech High School, as communicated in a letter sent to parents by the institution this week.
