A 17-year-old North Carolina girl faces murder charges for livestreaming a May 2026 attack on a San Diego mosque that killed three men, authorities said.
The girl, identified in court records as Sarah Lindsey Santiago, was arrested in late August 2026 and indicted by a Forsyth County grand jury on three counts of murder and one count of conspiracy. She is accused of recording and distributing live footage of the attack, which targeted the Islamic Center of San Diego, and of publishing the manifesto of the shooters, Caleb Vazquez and Cain Clark.
The Attack and Its Aftermath
The shooting occurred on May 18, 2026, when Vazquez, 18, and Clark, 17, stormed the San Diego mosque, killing security guard Amin Abdullah, caretaker Mansour Kaziha, and Nadir Awad. The attackers, who had planned to later target a Jewish temple and a Black high school, took their own lives hours later in a car near the mosque. Authorities said the girl was not physically present but aided the attack by livestreaming the violence and distributing the shooters’ manifesto.
The law in North Carolina is clear: A person may be guilty of a crime, although he or she personally does not do any of the acts necessary to constitute the crime,
said Forsyth County District Attorney Jim O’Neill, who emphasized that aiding and abetting carries the same penalties as direct participation. The girl, who could face life without parole if convicted, was also accused of purchasing a white supremacist patch for one of the shooters to wear during the attack.
Radicalization and Online Networks
O’Neill described the shooters as part of an underground subculture of hate
that uses encrypted platforms to radicalize individuals. It’s an echo chamber of intense hate against different cultures and religions,
he said, noting that Vazquez and Clark’s manifesto expressed animosity toward all racial, religious, and political groups.
The FBI’s Charlotte Field Office, which led the investigation, said the case highlights the dangers of online radicalization.
Legal and Ethical Implications
The indictment raises questions about legal liability for digital bystanders. O’Neill argued that sharing live footage of violence constitutes complicity, stating, The goal of publishing the livestream was to ‘memorialize the two terrorists.’
He urged parents to monitor children’s online activity, noting that the girl had access to extremist content through social media and messaging apps.
Community Response and Unanswered Questions
The San Diego community mourned the victims, with members describing them as heroes who protected 140 children at the mosque’s school during the attack. The shooters had stockpiled 30 guns and a crossbow, according to the CBS News report. The Vazquez family, in a written statement, said Caleb had been on the autism spectrum and had struggled with identity issues, which they believed contributed to his radicalization.
While the girl’s trial date has not been set, the case has sparked debates about the legal boundaries of digital participation in violence. However, no further details about potential federal charges or the girl’s defense strategy have been released.
