Teen Charged as Adult with Murder in San Diego Mosque Attack
A North Carolina grand jury indicted 17-year-old Sarah Lindsey Santiago on August 31 on three counts of first-degree murder and conspiracy for allegedly aiding two gunmen in a deadly California mosque attack. Prosecuting authorities confirmed Santiago will be tried as an adult for her alleged role in assisting the shooters as they broadcast the assault live, distributed hate material, and procured equipment worn during the killings.
Grand jury details online coordination and planned secondary targets
Court documents released by prosecutor James O’Neill’s office allege that Santiago actively assisted 18-year-old Caleb Vazquez and 17-year-old Cain Clark during their May 18 rampage at the Islamic Center of San Diego. Vazquez and Clark killed three men, including an on-duty security guard, before taking their own lives.
Indictment records show Santiago purchased a patch featuring a pro-Nazi “Sonnenrad” symbol for Vazquez, which he wore throughout the shooting. Beyond facilitating the live internet broadcast and disseminating the attackers’ written manifesto across the web, the grand jury determined that Santiago collaborated with the gunmen on unrealized plans to attack a Jewish temple and African-American high school students.
The formal charges link directly back to the May 18 violence at the Islamic Center of San Diego, establishing legal accountability for out-of-state digital facilitators in mass casualty incidents.
